Authors: Mahesh Pushpalatha , Ainapur Md. Mohsin , Pradeep Krishna
Published: September 2021

Pathology specimens are invaluable study adjuncts. While the storage and handling of these specimens may be cumbersome, their preservation in suspensions such as formalin for a longer period may result in objectionable odour, discolouration and irritation. These disadvantages can be overcome by an alternate technique called as “Plastination”. This technique is fast emerging as a method for conservation of pathological specimens. This review lays emphasis on the process, technique and potential uses of plastination in conservation of pathological specimens.

The study investigated the effect of head teachers’ support for teachers’ professional development on inclusive education implementation. Bartalanffy (1969) open systems advocates for head teachers to utilize management initiatives with partnerships to implement inclusive education. Descriptive survey was applied, and Chi-square tested the null hypothesis. Questionnaires were administered to 71 head teachers and 297 teachers, supplemented by document analysis. Interview was used on eight Quality Assurance Standards Officers (QASOs) and four Education Assessment Resource Centre Officers (EARCs). Quantitative data was coded and analyzed using descriptive statistics, and presented in frequency tables and bar graphs. Qualitative data was coded, transcribed and presented in narrative form. Both quantitative and qualitative data findings were discussed in juxtaposition with confirming or refuting the research evidence, and reinforcing the interpretation. The Chi-square results established that there was relationship between head teachers’ support for teachers’ professional development with inclusive education implementation. However, majority of head teachers and teachers lacked specialized skills in assessment of diverse learners, 77.5% and 80.5%; behaviour management, 74.7% and 79.1%; differentiated teaching, 80.3% and 81.1%, derailing teachers’ productivity and learners’ performance. Therefore, it was recommended that head teachers in collaboration with multi-agencies facilitate teachers’ inclusive education training in order to effectively implement inclusive education.

Bacterial blight (BB) caused by X. oryzae pv. oryzae is a destructive disease of rice and causes 30-50% losses to rice depending on the outbreak. Development BB resistant rice varieties have long been considered as one of the most effective approach to control the disease. However, the durability of host resistance is breaking down due to the change of pathotypes of X. oryzae pv. oryzae globally. Pathotypic analyses of 239 X. oryzae pv. oryzae Bangladeshi isolates on Near Isogenic Lines (NILs) containing resistance (R) gene (s) revealed the existence of eight pathotypes of X. oryzae pv. oryzae. Among eight pathotypes, pathotypes IV and V were considered as major comprising  maximum number of isolates, (30.13% and 23.01%, respectively), whereas pathotype VIII considered as minor consisting only 2.51% of total isolates. Pathotype, I showed highest virulence or aggressiveness compatible with all NILs, whereas pathotype VIII exhibited lowest virulence to these NILs. Bacterial blight resistant genes viz. Xa1 (75.00%), Xa11 (62.50%) and Xa21 (50.00%) showed resistance to most of the pathotypes while Xa4 performed worst as compared to all others R-genes. In pyramid lines, IRBBB63 (Xa5+Xa7+Xa13) and IRBB57 (Xa5+Xa7 +Xa21) showed resistance reaction and IRBB61 (Xa4+Xa5+Xa7), IRBB60 (Xa4+Xa5+Xa13+Xa21), IRBB54 (Xa5+Xa21), and IRBB53 (Xa4+Xa21) showed susceptible reaction to X. oryzae pv. oryzae pathotypes. These results collectively indicated the deployment of Xa1, Xa11, Xa4, Xa5, Xa7, Xa13 and Xa21 either alone or in combination against BB would be a best choice for the development of BB resistant rice varieties in Bangladesh.

Published: September 2021

A study was carried out in Dailekh, Nepal with an objective to assess the mandarin orchard management practices and their level of adoption by mandarin growers of Dullu municipality. All together 60 respondents were selected for the household survey in major citrus-producing wards of Dullu by following the simple random sampling technique. Primary data were collected by administering the pretested questionnaire and; descriptive and inferential statistics were computed using Ms-Excel and SPSS. The result showed that the majority of the respondents were from Brahmin ethnicity (43.3%), middle-age group i.e. 35-49 years (53.3%), and male (70.0%). Furthermore, most of them belonged to medium size family of 5-8 members (60.0%) and were earning most of their income through agriculture (80.0%). The result of the study revealed the variation in the scale of adoption of different management practices. Most of the households had adopted pruning and applied farmyard manure (FYM) while the least of them had adopted mulching and applied chemical fertilizer. Chi-square test revealed that the factors such as age (p=0.042), education level (p=0.007), family size (p=0.029), and training exposure (p=0.001) were significantly associated with the level of adoption of these practices. Incidence of insect-pests and diseases (I=0.88), frequent occurrence of climatic hazards such as hailstorms (I=0.71), and limited irrigation facility (I=0.70) were the major problems of mandarin growing households. It is recommended that improving access to irrigation facilities, use of certified planting material, mulching application and use of appropriate dose of manure and fertilizer must be prioritized in the study area.

Published: September 2021

A field experiment was conducted at Horticulture farm of Nepal Polytechnic Institute (NPI) Bharatpur-11, Chitwan to study the effects of different doses of vermicompost on growth, yield and quality of radish (Raphanus sativus L. cv. Mino Early) from January 2020 to March 2020. Five different doses (0 ton, 5 ton, 10 ton, 15 ton, and 20 ton per hectare) of vermicompost were taken as treatments and the experiment was replicated four times. The experiment was set up in Randomized Complete Block Design (RCBD). The result of the study showed that there was a significant effect of different doses of vermicompost on plant height, the number of leaves per plant, spreading of the plant, root length, root weight per plant, root diameter, and root yield at harvesting. The maximum plant height, the maximum number of leaves per plant and maximum plant spreading in radish plant on vermicompost application was recorded every 30, 45 and 60 days after sowing (DAS). The maximum root length (29.60 cm), maximum root diameter (36.27 mm), maximum root weight (191.8 g), maximum biomass weight (241.6 g/plant), maximum root yield (47.9 ton/ha), were recorded on applying 15 ton/ha vermicompost at 60 DAS. The control treatment showed the minimum vegetative growth and yield. Among the different doses of vermicompost, the overall performance of radish was found better in 15 ton/ha of vermicompost. Statistical analysis showed no differences among (5 ton, 10 ton, 15 ton, 20 ton per hectare of vermicompost) applications. Hence, 5 ton per hectare of vermicompost application will be best for radish production in Chitwan.

A field study was conducted at research field of Spices Research Sub-Centre (SRSC), Faridpur, Bangladesh to find out the efficacy of weed management practices on the growth, yield, quality and economics of onion with the variety BARI Piaz-6. Thirteen treatments such as: T1-control as check (no weeding), T2-weed free, T3-one hand weeding (HW) at 45 days after transplanting (DAT), T4-two HW at 25 and 45 DAT, T5-three HW at 25, 45 and 65 DAT, T6-pre-emergence (PE) spray of pendimethalin 33 EC @ 330g a.i/litre + one HW at 45 DAT, T7- PE spray of pendimethalin 33 EC @ 330g a.i/litre + two HW at 45 and 65 DAT, T8- post emergence (POE) spray of pendimethalin 33 EC @ 330g a.i/litre at 25 DAT + one HW at 65 DAT, T9- PE spray of oxyfluorfen 23.5 EC @ 235g a.i./litre + one HW at 45 DAT, T10- PE spray of oxyfluorfen 23.5 EC @ 235g a.i./litre + two HW at 45 & 65 DAT, T11- POE spray of oxyfluorfen 23.5 EC @ 235g a.i./litre at 25 DAT + one HW at 65 DAT, T12- PE spray of pendimethalin 33 EC @ 330g a.i/litre + POE spray of oxyfluorfen 23.5 EC @ 235g a.i./litre at 45 DAT + one HW at 65 DAT and T13- PE spray of oxyfluorfen 23.5 EC @ 235g a.i./litre + POE spray of pendimethalin 33 EC @ 330g a.i/litre at 45 DAT + one HW at 65 DAT were compared by randomized complete block design with three replications. The study revealed that the weed management treatments under the study significantly influenced all parameters except total soluble solid content of onion bulb. Weed density had reverse effect on growth, development and yield of onion. Among the weed’s infestation, Cyperus rotundus (55-60%), Echinochloa crusgalli (10-15%) and Chenopodium album (8-10%) were predominant. The highest weed density (137.25 weeds/m2) were recorded from the T1. The lowest weed density (15.24 weeds/m2) were observed from T13. The T3 had the least weed control efficacy (23.56%). The maximum fresh yield (19.49 t/ha) of onion bulb were obtained from T2 followed by T13 (19.31 t/ha). The highest benefit-cost ratio (2.19) was calculated from the T13 closely followed by T12 (2.18). From this study it was concluded that Pre-emergence application (PE) application of oxyflourfen or pendimethalin + post-emergence (POE) application of oxyflourfen or pendimethalin at 45 DAT (days after transplanting) + once HW (hand weeding) at 65 DAT and also PE of oxyflourfen or pendimethalin + twice HW at 45 & 65 DAT exhibited good performance to control weeds in onion field.
Factors influencing adoption of major orchard management practices in mandarin orange of Gorkha: A case from mid-hills of Nepal
Authors: Poudel Ashutosh , Kattel Rishi Ram , Adhikari Gaurav
Published: September 2021

The mid-hills of Nepal have immense potential for mandarin orange production. However, its productivity is declining over the years despite an increasing trend in the cultivated area. Since the proper adoption of orchard management practices has been associated with increased productivity, it is, therefore, an imminent requirement to sustain the mandarin orange production for long in the country. Therefore, a research survey was carried out to assess the adoption of major orchard management practices and identify factors affecting its adoption so that the insights from this finding would provide potential policy implications for the rejuvenation of the declining orchards.  Altogether, 93 households from Gandaki and Sahid Lakhan Rural municipalities, as well as Gorkha Municipality from Gorkha district were chosen for the study using a simple random sampling technique. Data were collected with a semi-structured interview which was analyzed using SPSS and Stata software. A seemingly unrelated regression (SUR) logit model was used for triangulating the effect of different variables on the adoption of major mandarin orange orchard management practices. The findings revealed that nearly two-third of the households reported citrus decline in their orchards. Further, the adoption of major orchard management practices was mostly found driven by regular access to extension agents, and the income generated from agriculture. Nevertheless, the adoption was plagued by the prevalence of citrus decline in the orchard. In light of these findings, participatory training programs related to the rejuvenation of declining orchards, regular advisory and extension services, and input subsidies to the smallholding farmers are suggested so that the adoption of major orchard management practices gets increased among the mandarin orange farmers.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during December 2017 to May 2018 to study growth performance of aromatic Boro rice (cv. BRRI dhan50) in response to nitrogen and potassium fertilization. The experiment consisted of four levels of nitrogen viz., 0, 50, 100 and 150 kg ha-1, and four levels of potassium viz., 0, 30, 60 and 90 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. The results revealed that nitrogen and potassium fertilization and their interaction exerted significant influence on growth performance of BRRI dhan50. Application of 100 kg N ha-1 produced the tallest plant (82.17 cm), the highest number of tillers hill-1 (10.08) and chlorophyll content (52.21) at heading stage. While, application of 90 kg K ha-1 produced the tallest plant (81.44 cm) at physiological maturity stage, the highest number of tillers hill-1 (9.66) and chlorophyll content (51.54) at heading stage. In case of interaction, the tallest plant (85.33 cm), the highest number of tillers hill-1 (10.83) and chlorophyll content (58.28) were obtained from 100 kg N ha-1 along with 90 kg K ha-1 at heading stage. Therefore, application of 100 kg N ha-1 along with 90 kg K ha-1 interaction appeared as the promising practice in aromatic rice (cv. BRRI dhan50) cultivation in terms of growth performance.

Authors: Kaduyu Issa , Musinguzi Patrick
Published: September 2021

This study evaluated the impact of irrigation and cropping on soil physicochemical properties at Kyekide small scale irrigation farm in Jinja district, eastern Uganda. Treatments included Land-use systems under perennial and annual cropping with and without irrigation for over 20 years. The hypothesis was that there were insignificant differences in physicochemical properties of the soil under irrigated and non-irrigated cropping systems. Soil physical properties except hydraulic conductivity was not significantly different with irrigation and cropping. The pH of the soils ranged from moderately acidic to neutral pH (5.17-7.40), with irrigated soils tending to be more neutral than non-irrigated soils. SOM content was higher in the irrigated soils and perennial soils than in the non-irrigated and annual soils. The soils were moderately deficient in N and severely deficient in P (mean values =0.175% N and 1.183mg kg-1 P) compared with the critical of 0.2% and 15 mg kg-1, respectively. Irrigated soils had a significantly higher Na+ content than non-irrigated soils, with a mean value of 2.985cmol/kg. The K+, Ca2+, and Mg2+ contents were higher in irrigated and perennial soils than non-irrigated and annual soils. The study suggested monitoring the soils under an irrigation scheme to prevent degradation due to increased salt accumulation or chemical fertility decline. Overall, monitoring of soil quality is vital in irrigation schemes to monitor the impacts of water on the environment.

Published: September 2021

The study was conducted in the Sheringal Valley of the Khyber Pakhtunkhwa Pakistan, to investigate the Bryophytes species of the area. It is the first attempt to document the Bryophytes species in the selected area. A total of 27 moss species (20 genera, 14 families), 16 liverwort species in 13 genera, 8 families and two species of hornwort have been reported from sheringal valley. Sheringal valley has a more typical tropical bryoflora, fewer thallose liverworts and moss taxes are also found. A richer habitat variety including dry and wet habitats, as well as its bigger area, seem to account for the higher number of the bryophyte species in sheringal valley. Most bryophytes in sheringal valley are epiphyllous (30%), saxicolous (20%), Corticolous (40%) and terrestrial (10%).

Horse purslane is one of the most spreading and problematic weed in Pakistan’s Punjab region during summer. A field experiment to check the interference of horse purslane (Trianthema portulacastrum L.) on growth and yield of soybean was conducted at research area of MNSUniversity of Agriculture Multan in summer, 2018 The experiment was carried out in Randomized Complete Block Design (RCBD) having three replications and comprising of ten treatments i.e. Weed free (whole season), horse purslane free till 20 Days after emergence (DAE), horse purslane free till 40 DAE, horse purslane free till 60 DAE, all weeds free 20 DAE, all weeds free 40 DAE, all weeds free 60 DAE, Weedy check (except horse purslane), weedy check (only horse purslane), weedy check (all weeds). According to standard procedure data of growth and yield parameters of soybean and weeds were taken.Data was statistically analyzed by using Fisher’s analysis of variance (ANOVA) method. Comparison of employed treatment means were done with honest significant difference (HSD), Tukey’s test at 0.05 probability. The maximum biological yield was achieved in plots kept weed free over crop growth cycle 6536.0 kg ha-1 and statistically minimum yield achieved inweeds free (whole season(5145.4 kg ha-1). While T7all weeds free till 60 DAE and T4horse purslane free till 60 DAE treatments attained 6345.8 kg ha-1 and 6251.8 kg ha-1, respectively.T9 (weedy check only horse purslane) horse purslane sole caused 10.81 percent more yield reduction as compared to T10 (weedy check all weeds). Based upon the study, it is suggested that horse purslane should be controlled in soybean fields till 45 DAE to get benefits as the control single weed is economical as compare to all weeds.
RESPONSE OF BITTER GOURD (Momordica charantia) TO CULTURAL AND CHEMICAL WEED CONTROL METHODS
Authors: Ilyas Mohammad
Published: September 2021

Experiments were conducted at the farm of the University of Agriculture Peshawar in 2012 and 2013 to evaluate the effect of different weed control methods in bitter gourd. The treatments comprised of four mulches (Rumex crispus, Silybum marianum, news papers, and saw-dust), a herbicide i.e. Stomp 330 EC (pendimethalin) applied as pre-emergence, a hand weeding and a control treatment (weedy check). Data were collected on weed biomass, number of plants ha-1 and fruit weight. The parameters were significantly affected by the applied treatments during both the years. Weed biomass in 2012 and 2013 was the highest (2971 and 3595 kg ha-1, respectively in the weedy check treatments and lowest in hand weeded plots (68 and 83 kg ha-1) in 2012 and 2013, respectively. Moreover the effect of the mulching treatments and the herbicide treatment were statistically at par with each other and different from the weedy check. The highest number of plants ha-1 (9773 and 8077) and fruit weight plant-1 (756 and 657 g) were recorded in the hand weeded treatments in 2012 and 2013, respectively. Hand weeding was followed by the treatment of Stomp 330 EC with the respective values in the two years as 8834 and 7301 plants ha-1, and 667 and 580 g plant-1 in 2012 and 2013, respectively. Moreover, the performance of the mulching treatments was also significantly more effective than the weedy check plots. Mulches of S. marianum and R. crispus reduced the weed biomass to 1072 and 1615 kg in 2012 and 1297 and 1954 kg in 2013 as compared to the weedy control with weed biomass of 2971 and 3595 kg ha-1 in 2012 and 2013, respectively. The respective no. of plants ha-1 for the mulches of S. marianum and R. crispus were 8548 and 8489 in 2012 and 7065 and 7016 in 2013 whereas and the fruit weight plant-1 was 435 and 396 in 2012 and 378 and 344 g in 2013. Keeping in view the good performance of weed biomass as mulches, the cost of production and the environmental safety, the hand weeding and herbicide use cannot be preferred alone for use as weed management tools. Therefore, the herbicide use and hand weeding should be used only on casual basis or in emergency; and the mulching methods should be adopted in the long run as mulching method is not only good for weed control but also for maintaining the soil fertility, moisture conservation, and environmental safety.
SEED POLYMORPHISM OF RHYNCOSIA CAPITATA (ROTH) DC. ENHANCE ITS TOLERANCE TO VARYING TYPE AND INTENSITY OF SALT STRESSES
Authors: Abbas Tasawer
Published: September 2021

Increasing soil salinity due to climate change complicating weed management. Rhynchosia capitata is becoming an increasing problem in summer crops, such as cotton, soybean, pearl millet and mungbean worldwide. Study was conducted to evaluate the impact of four types of salts stresses (NaCl, Na2SO4, CaCl2 and NaHCO3) at six different levels (0, 50, 100, 150, 200 and 250 mM) on R. capitata seeds of different sizes including small, medium and large. Results revealed that R. capitata can germinate over a wide range of salt stress but as the salinity level was increased to 250 mM the germination percentage and seedling growth decreased significantly. Larger seeds have more potential to germinate and grow vigorously at an increased salt concentration as compared to medium and small seeds. Salt stress caused 40-73%, 59-96% and 40-100% inhibition in seed germination, seedling length and dry weight, respectively. Among various salt stresses CaCl2 showed less inhibition of R. capitata. The higher tolerance of this weed to wide range of salt stresses is alarming factor under current and anticipated increase in salinity, as it will disturb management plans by changing critical completion period and threshold level due to more adaptability of weed under stress than crop plants.
A, The ESTIMATION OF ECONOMIC THRESHOLDS OF JUNGLE RICE (ECHINOCHLOA COLONA L.) AND FALSE AMARANTH (DIGERA ARVENSIS FORSSK.) IN DIRECT SEEDED RICE
Authors: Ehsan Amir , Safdar1 Muhammad Ehsan , Ali Amjed
Published: September 2021

ABSTRACT There is little understanding about ecological interference of weeds in direct-seeded rice. To get estimates of economic thresholds of two weeds in direct seeded rice, two-year field trials were conducted at research area of College of Agriculture, University of Sargodha, Punjab-Pakistan. Treatments included 0, 22, 44, 66 and 88 plants m-2 densities of each of Echinochloa colona and Digera arvensis laid out in randomized complete block design. Augmented densities of E. colona (0, 22, 44, 66 and 88 weed plants m-2) enhanced its plant dry biomass up to 348 and 353%; and relative competitive index maximally to 80 and 77% in years 2015 and 2016, respectively. While the corresponding increases in plant dry weight and relative competitive index of D. arvensis were 367 and 360% and 79 and 82%. The enhancement in N (up to 258 & 257 %), P (up to 220 & 232%) and K (up to 293 & 301%) uptake in years 2015 and 2016, respectively were made by E. Colona whereas the corresponding increases in N, P and K assimilation by D. arvensis were as far as 265 & 257%, 238 & 233% and 305 & 298%, respectively. The declines in growth and yield of rice were observed in response to growing number of both the weeds. Rice grain yield losses ranged between 9.8 to 80% and 28 to 80% by E. Colona and D. arvensis. The economic thresholds of false amaranth and jungle rice were estimated to be 1.6-1.4 plants m-2 and 2.2-2.6 plants m-2, respectively.

Abstract-Tyrosinase is a key enzyme of melanogenesis which determines the mammalian skin, hair and eye colour. Hyper-pigmentation leads to various skin disorders like melasma, sunspots, age spots and freckles. Moreover, abnormal skin pigmentation is a serious aesthetic concern which leads to psychosocial problems. Thus to achieve melanin inhibition, inhibition of tyrosinase might be an effective approach. To this end we prepared methanolic (MeOH) extracts from leaves and roots of Allium sativum (AS) and Mentha piperita (MP), which were further processed for 1:1 fractional distillation to prepare methanolic n-hexane (MeOH_n-Hx), methanolic ethyl acetate (MeOH_EA) and methanolic chloroform (MeOH_CHCl3) extracts, aiming to evaluate tyrosinase and anti-oxidant activities in-vitro. Our results confirmed that all MeOH-crude AS and MP extracts showed significant anti-oxidant activity with IC50 values ranging from 0.05 ± 0.2 mg/ml to 4.3 ± 2.3mg/ml. Moreover, AS and MP all 16 extracts have significant anti-tyrosinase activity with IC50 range from 0.014 ± 0mg/ml to 1.205 ± 0.07mg/ml. Interestingly, AS leaf MetOH_EA, AS leaf MetOH_CHCl3, AS root MetOH_EA and MP leaf MetOH_CHCl3 showed significant anti-tyrosinase activity even higher than positive control kojic acid. AS leaf MetOH_CHCl3 extract being the most potent among all tested extracts is proposed as potential candidate to treat tyrosinase rooted hyper-pigmentation in future.

Authors: YASEEN TABASSUM
Published: September 2021

The present study was conducted to assess the allelopathic potential of Zizypusmauritiana against some crop species. Plant materials of Z.mauritiana were collected from Ahmad Abad District Karak and dried at room temperature (25-30˚C). Allelopathic studies conducted by using aqueous extracts from various parts including mature leaves, bark, fruit rain water and mulching in various experiments invariably retarded the germination, plumule, radical growth, fresh and dry weight of Trictium aestivm, Zea mays, and Cicer arietinum., used as a test species. The aqueous extracts obtained after 48 h were more inhibitory than 24h. Leaves were more toxic than fruit and bark. Rain water and mulching experiments also proved to be inhibitory. It is suggested that the various assayed parts of Z.muritianahave strong allelopathic potential at least against the tested species. Further investigation is required to see its allelopathic behavior under field condition against its associated species and to identify the toxic principle.

Weed management practices included 1) Control, 2) Hoeing 15 days after sowing 3) Hoeing 15 and 30 days after sowing 4) Hoeing 15, 30 and 45 days after sowing, and 4) Herbicide (nicosulfuron) were kept into the subplots. The results revealed that chisel plough + rotavator has significantly reduced weeds m-2 (122, 101 and 125 weeds m-2), weeds fresh weight (19.73 g m-2, 116.35 g m-2 and 252.56 g m-2) and weeds dry weight (6.83 g m-2, 38.69 g m-2 and 80.61 g m-2) at 30, 45 and 60 days after sowing, respectively. The operation of chisel plough + rotavator has produced tallest plants (221.22 cm) with maximum grain rows ear-1 (16), grain yield (3586 kg ha-1) and shelling percentage (78.14%). Among weed control methods, hoeing 15, 30 and 45 days after sowing revealed maximum plant height (226.41 cm), grain rows ear-1 (16), grain yield (3604 kg ha-1) and shelling percentage (79.11%). All weed control methods have showed significant reduction in weeds m-2, weeds fresh weight and weeds dry weight. Interaction was also found significant for weeds m-2 at 60 DAS and grain yield of maize. Lowest weeds (56 weeds m-2) at 60 DAS and highest grain yield (4569 kg ha-1) was recorded when seedbed was prepared with chisel plough + rotavator with 3 hoeings (hoeing 15, 30 and 45 days after sowing). It is concluded that treatment of chisel plough + rotavator and hoeing 15, 30 and 45 days after sowing has significantly produced maximum grain yield of maize crop.

ABSTRACT Chemical weed control method caused environmental hazards and residual effects in crops and soil. Alternate approach to control weeds is getting attentions in sustainable production system. Use of aqueous extracts of weed is getting scientific attention as eco-friendly alternative to chemical herbicides especially under scenario of fast increasing herbicide resistance in weeds. To investigate the herbicidal potential of aqueous extract of winter weed of Sonchus oleraceus L. (Sow thistle) on summer weed Oryza punctate L. (red rice) seed emergence and initial seedling growth, a study was planned. In this study, seeds of O. punctate were incubated in seven concentrations (0, 0.25, 0.50, 1, 2, 4, and 8%) of different parts i.e. leaves, stem, flower of S. oleraceus. All the tested concentrations of various plant parts of S. oleraceus significantly inhibited the mean emergence time, emergence index, emergence percentage (%), time taken to 50% emergence as well as growth of O. punctata weed. However, maximum mean emergence time (5.26 days), minimum germination index (1.69), germination percentage (40%), root length (2.04 cm), shoot length (5.71 cm), fresh weight (59 g), dry weight (4.06 g) was noted at 8% concentration with fruit aqueous extract of S. oleraceus. Seed of O. punctata take maximum time to complete 50% emergence (3.33 days) under control where we applied distilled water. Results suggested fruit extract of S. oleraceus at 8% concentration can be used potential bio-herbicide for the control of O. punctate. Key words: Chemical, eco-friendly, herbicidal potential, fruit extract

The Admissibility of Scientific Expert Evidence Under Indonesian Criminal Justice System
Authors: Sulistyani Wanodyo
Published: September 2021

In many cases, such as corruption and forestry-related crimes, an expert has a significant role in explaining the impact of the crime. For instance, scientific expert evidence is required to disclose about the ecological destruction that occurred due to the defendant's criminal activities. In practices, the issue with scientific expert evidence is supposed to be about its admissibility in court. For this issue, the U.S. Court applies Rules of Evidence in considering the admissibility of scientific expert evidence at trial. Those are some requirements (prong test) to be met before expert testimony is admissible. In contrast, the Indonesian Criminal Procedural Law (KUHAP) or other laws do not set any prong test for presenting specialist scientific evidence to be acceptable. Lack of such proof may impact criminal justice process reliability and place expert under vulnerable position. Therefore, this paper will explore the issue on scientific expert evidence under Indonesian criminal law as well as its consequences and impacts for the Indonesian criminal justice process.

Published: September 2021

The regulation of Warehouse Receipt System (WRS) in Indonesia written in The Law No. 9 of 2011 concerning Amendment of WRS is expected to be useful and to facilitate farmers of WRS. However, in its practice, WRS in Indonesia was not yet able to improve the credit amount of banking with warehouse receipt as a guarantee. Malang Regency is one of the potential areas of farming products in East Java and once built WRS in 2012, so it is interesting to make this area as a research object in terms of reviewing WRS regulation in Indonesia. The issue is whether the purpose of establishing the law on WRS gave advantage and credit expediency, particularly for small farmers. This article is empirical legal research with a socio-juridical approach by describing the implementation of farm credit through WRS, describing the farmers’ utilization of WRS in Malang Regency, then, analyzing it using regulation of warehouse receipt in Indonesia and the theory of legal effectiveness. Overall evaluation of WRS in the mentioned area shows that some parties, such as farmers, unit cooperation village, and local government, are at a loss. The evaluation result of WRS regulation implementation cannot realize the goals of the law on WRS; those are giving easy, affordable, and fast access to farmers in getting capital. The WRS cannot give advantage for small farmers. The policy of WRS in Indonesia has not yet been able to help farmers to challenge the competition in the free-trading market through ASEAN Economic Community. The researchers suggest that the WRS regulation must be made and integrated with farmer’s policy so it can give advantage for small farmers.

In the unilateral claim, every determination of a territory is the right of a sovereign state and does not require agreement with international organizations or other countries. Especially regarding the borders of a country, many international regulations require a joint determination (bilateral or multilateral). The norm will impact the absence of responses from another country, or such a country does not react because its interests were not disturbed. China's unilateral statement over the South China Sea has tried to dominate globally, and at the same time, there has been no stabilization of peace. It will likely continue, expand, and have long-term adverse impacts on the regional economic and security situation in the region. China's unilateral claims in the South China Sea have also resulted in other warring countries, strengthening their presence and claims. This research uses normative approach which examines the unilateral claims under international law in the South China Sea especially in the UNCLOS 1982 and other related international law instruments. As a result, for China, it is necessary to improve its current position, at least it needs to negotiate in the future. Countries which is involved in the South China Sea should clarify and submit territorial claims and maritime rights under international law, including the UNCLOS 1982.

Published: September 2021

The rate of sexual violence against children in Indonesia is very alarming. Perpetrators of sexual violence against children are usually adults close to the victim, including family members and neighbors. Sexual violence is a violation of human rights. Sexual violence deprives the victim of security and protection, the right to prosper physically and spiritually, the right to be free from torture or treatment that demean human dignity, and the right to live. Chemical castration stipulated in Law No. 17 of 2016 is a form of punishment that is not under criminal law policy in Indonesia, which is based on Pancasila and the 1945 Constitution. Chemical castration formulated in Article 81 Paragraph (7) is not following the values of Pancasila, especially the first principle, namely belief in One and Only God, and the second principle, just and civilized humanity. Substantially, the castration penalty causes an individual to lose the right to continue the lineage and fulfill basic needs as guaranteed in Article 28B paragraph (1) of the 1945 Constitution. The same thing is stated in Article 10, paragraph (1) of Law No. 39 of 1999 concerning Human Rights.

Published: September 2021

Currently, competitiveness is a priority indicator for any country and in order to secure achieving its high level, some measures were developed aimed at formation of favorable conditions for the creation and implementation of innovations. It is the implemented innovative projects that have a positive impact on the economic status of the state. Innovati v e potential is considered the “foundation” for innovation, since its structure includes all the fundamen- tal components, facilitating the passage through all the stages of the innovation cycle. The country’s indicators are formed from a set of economic indicators of the regions, so the policy of local self-government bodies of the subjects of the Russian Federation should be aimed at innovative development and, in partic- ular, at building up the innovative potential of the region. The article analyzes various interpretations of the definition of “innovative potential of the region” and considers its structure and main components . Also based on the difference in approaches to the definition, a terminological classification is compiled from the point of view of Russian and foreign scientists who are engaged in research in the field of innovation. It is known that high practical results can be obtained when there is a necessary theoretical basis for that, in which the essence of all terms is revealed.

A sportpszichológiai módszereket számos teljesítményhelyzetben alkalmazzák, így pl. előadóművészek és katonai/taktikai egységek munkáját is segítik sportpszichológusok. A katonák számára e teljesítményhelyzetek sokkal súlyosabb következményekkel járnak, mint a sportolók esetében. A sport és a katonaság nagyon sok szempontból hasonlít egymásra: részben az előbbi az utóbbiból származik, másrészt mindkét területen a csapatok is komplex, folyton változó környezetben összehangoltan kell, hogy együttműködjenek, kognitív és motoros készségeik használatával. Az USA-ban az 1990-es évek eleje óta készítik fel mentális tréning segítségével a katonákat, manapság a Comprehensive Soldier Fitness Performance and Resilience Enhancement Program (CSF-PREP) kezdeményezést alkalmazzák, amely a hadseregben dolgozók és családtagjaik egészségének és teljesítményének javítását célozza, valamint ennek keretében sportpszichológiai módszerek használatát kínálja, továbbá ezek kutatásokkal alátámasztott ellenőrzését végzi.
