Weeds are plants whose existence is not expected by farmers because they interfere with cultivated plants. But there are weeds that can produce phenolic compounds such as Clidemia hirta L which can be used as bioherbicides. This study aims to determine the effect of Clidemia hirta L. leaf extract on the germination and growth of Praxelis clematidea weeds. The research was carried out from June 2021 to September 2021 at the Weed Science Laboratory and Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. This study used a completely randomized design (CRD) method with 6 treatments with concentrations of Clidemia hirta L leaf extract, namely 0; 1.5; 3.0; 4.5; 6.0; and 7.5%. Each treatment was repeated 6 times to obtain 72 experimental units. The observed variables are germination, crown height, root length, dry weight, and weed poisoning level. The data obtained were analyzed by analysis of variance and continued with the Least Significant Difference Test (LSD) at the 5% level. The results showed that the germination of Praxelis clematidea weed was significantly inhibited by the treatment of Clidemia hirta L leaf extract with a concentration of 1.5; 3.0; 4.5; 6.0; and 7.5%. While concentrations of 3.0%, 4.5%, 6.0%, and 7.5% Clidemia hirta L. leaf extract  inhibited the growth of Praxelis clematidea weeds in the greenhouse. Key words:  Clidemia hirta L., extract, Praxelis clematidea, germination, growth

The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. The conventional method of removing pulp from cocoa seeds is done mechanically by rubbing the seeds with rubbing ash. Conventional pulp removal has disadvantages, such as being less practical and potentially damaging the seed surface. Therefore, it is necessary to try chemically removing the pulp from cocoa seeds by soaking the seeds in a lime solution (CaCO3). This study aims to determine the effect of the duration of cocoa seed soaking in CaCO3 solution and different planting media compositions on seedling growth. The research was conducted from September to December 2021 at a plastic house in Labuhan Dalam Village, Tanjung Senang District, Bandar Lampung, and the Seed Laboratory, Faculty of Agriculture, University of Lampung, Gedong Meneng, Bandar Lampung. The study used a Completely Randomized Design (CRD) arranged in a factorial manner. The first factor was the duration of cocoa seed soaking in CaCO3 solution, consisting of no soaking, soaking for 30, 60, 120, and 240 minutes. The second factor was the planting media composition, consisting of a mixture of rice husk charcoal + manure, sand + manure, and sand + rice husk charcoal + manure. Each treatment combination was replicated three times, resulting in 45 experimental units. The observation data were analyzed using analysis of variance, and the mean differences were tested using the Least Significant Difference (LSD) test at the 5% level. The results of the study showed that the duration of cocoa seed soaking in CaCO3 solution had no effect on cocoa seedling growth. The planting media composition of sand + rice husk charcoal + manure had a significant effect on the best cocoa seedling growth compared to the planting media compositions of rice husk charcoal + manure and sand + manure. Soaking cocoa seeds in CaCO3 solution had no effect on cocoa seedling growth in different planting media. Keywords : Cocoa seeds, pulp, CaCO3, soaking, planting media

The purpose of this research is to find out the form of student errors and the factors that cause student errors in solving three-dimensional questions on the concept of distance to points, lines, and planes. This research is qualitative research with a case study approach. The subjects of this study were 65 students of class XII in one of the high schools in Bandung, West Java. The instruments used were three-dimensional test questions and interview guidelines. To analyze student errors in this study, the Nolting theory was used. The results of this study show that students' errors in solving three-dimensional questions are still relatively high, with a percentage of careless errors of 54%, concept errors of 65%, application errors of 3%, and test-taking errors of 37%. These errors cause these errors because students do not master the prerequisite material well, misunderstand the concept of distance, and the ability to see space is still relatively low and not thorough. Based on the results of this study, it can be concluded that the biggest error of students in the third dimension is the concept error in determining the distance of points, lines, and planes. Therefore, it is expected that educators can pay attention to errors and their causal factors so that similar errors do not occur.

Authors: Mutammam Muhamad Badrul , Juniati Dwi , Khabibah Siti
Published: August 2023

Symbol sense is the intuitive feeling of calling out symbols in the process of solving problems. Professional teachers are teachers who have graduated from the Teacher Education Program (PPG). This qualitative descriptive study aims to describe the symbol sense ability of junior high school professional mathematics teachers. Three subjects are mathematics teachers who have passed PPG. Data were collected through six symbol sense tasks adapted from Jupri and Suspiyati and interviews. Assignments and interviews were analyzed using the triangulation method proposed by Miles, Huberman, and Saldana. The findings reveal that professional teachers tend to have good symbol sense abilities. In the second symbol sense characteristic, two out of three teachers display a poor symbol sense performance by manipulating the equation directly rather than reading the assignment in depth-first to get a better understanding so that they can complete the task correctly and efficiently. The teacher should improve his symbol sense ability.

Published: August 2023

The genetic divergence of forty bitter gourd genotypes was studied for sixteen different parameters by adopting Mahalanobis D2 statistics using Tocher's method. The genotypes were grouped into six clusters irrespective of geographic divergence, indicating no parallelism between geographic and genetic diversity. A maximum of 32 genotypes entered in cluster I, followed by 4 genotypes in cluster II. The cluster III, IV, V and VI had single genotypes each. The maximum inter-cluster distance was obtained between cluster II and VI (1620.05) while minimum distance was between III and V (103.32). Cluster V followed by cluster VI showed superiority for yield and other desirable traits, which indicate the potentiality of these diverse genotype collection for providing basic material for future breeding programmes.
Optimization of GA3 concentration for improved bunch and berry quality in grape cv. Crimson Seedless (Vitis vinifera L)
Authors: Satisha J , Pamu Sampathkumar , Upreti Kaushal Kishor
Published: August 2023

Crimson Seedless is a coloured seedless grape, gaining popularity in India for its attractive colour, bunch and berry quality with better shelf life. In cultivation of any seedless grape variety, application of GA3 at different stages is very much essential to produce good quality berries and bunches. However, this variety is highly sensitive to excess application of GA3 and practicing GA3 schedule similar to that of Thompson Seedless grapes adversely affects bunch quality. Hence, there was a need to standardize mild dose of GA3 just for rachis elongation which will help to reduce bunch compactness to a greater extent. Hence, an experiment was initiated to standardize concentration of GA3 for rachis elongation of Crimson Seedless grapes. Three different concentrations of GA3 {viz., 5 ppm (T1), 7.5 ppm (T2) and 10 ppm (T3)} were sprayed during pre bloom stage and compared with unsprayed control (T4). Among different treatments, pre-bloom spray of GA3@5 ppm could produce less compact bunches with highest average bunch weight, berry weight, berry length and TSS. However, bunches sprayed with 7.5 ppm and 10 ppm GA3 could also produce good quality bunches average berry weight and TSS was less. Because of severe coiling of rachis at 7.5 ppm and 10 ppm GA3 spraying, bunches were too straggly compared to spraying of 5 ppm GA3.  The control bunches without GA3 spray produced very compact clusters with less average bunch weight, berry weight, berry diameter and berry length.

Published: August 2023

Generation mean analysis study in bitter gourd was undertaken using six basic generations viz. P1, P2, F1, F2, B1 and B2 population derived from crossing gynoecious line (IIHRBTGy - 491) with two monoecious lines (IIHR Sel -19 -1 and IIHR Sel-78-4). The gynoecious parent was superior for node for first female flowering, number of fruits and yield/plant whereas the monoecious parents were superior for fruit length, fruit diameter and fruit weight. The superior performance of F1 over better parent indicated over-dominance of these traits. F2 plants were significantly diverse. B1 and B2 population exhibited mean value closure to their recurrent parents. Significance of one or more scaling tests, i.e. A, B, C and D in most of the traits revealed the presence of epistasis in both the crosses except for node bearing 1st male flower. Days to 1st female flower opening, node bearing 1st female flower, fruit diameter and yield showed presence of duplicate epistasis whereas days to 1st male flower opening, number of fruits per plant, fruit length and fruit weight showed complimentary epistasis in IIHRBTGy - 491 × IIHR Sel -19 -1 cross. Node bearing 1st female flower, fruit length, fruit diameter and yield showed presence of duplicate epistasis whereas days to 1st female flower opening, days to 1st male flower opening, number of fruits and fruit weight showed complimentary epistasis in IIHRBTGy - 491× IIHR Sel-78-4 cross. Additive gene action may be predominant for inheritance of node bearing 1st male flower.

Published: August 2023

Antigen-coated plate enzyme-linked immunosorbent assay (ACP-ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the presence and seed transmissibility of bean common mosaic virus-blackeye cowpea mosaic (BCMV-BICM) in farm- retained cowpea seed lots obtained from 46 locations, including markets and farms in major cowpea growing areas in the Ashanti and Brong Ahafo regions of Ghana. In the growout tests, virus symptomatic plants were observed in seedlings of 19 of the 46 seed lots tested under insect-proof screen-house conditions. All the symptomatic plants tested positive to polyclonal antiserum raised against BCMV-BICM in ACP-ELISA. The seed transmission rates based on symptoms ranged from 0 to 37.8 %. RT-PCR with primer pair designed to amplify the potyvirus Cylindrical Inclusion (CI) region resulted in an expected 720 bp DNA segment in 19 seed lots as a further confirmation of virus in the seed lots. The remaining 27 lots were asymptomatic and tested negative to BCMV-BlCM in both ACP-ELISA and RTPCR. The findings of this study revealed seed as the source of primary inoculum in the farmers’ fields and may aid in the implementation of control strategies such as discouraging farmers from retaining their own seeds for subsequent sowing and encouraging them to take appropriate measures in obtaining virus-free cowpea seeds from other sources.

Published: August 2023

Capsicum genus comprised of several cultivars is considered as an important spice crop worldwide. Roots play a vital role in a plant to mine water from the deeper layers of the soil. Although, characterisation for root traits have been made using different containers in many crops, such efforts for phenotyping root characteristics in Capsicum species are limited. Therefore, the experiment was initiated to find out the influence of container size on root characteristics and also to identify the appropriate container for high throughput phenotyping of Capsicum species for desirable root characteristics. Nine genotypes belonging to different Capsicum spp. were grown in three types of containers having different dimensions. Among the three types of containers, the bucket type container with dimension of 32 cm height 30 cm diameter with 23 kg soil media capacity was most suitable for phenotyping root characteristics compared to PVC pipe and pot type. Subsequently, 18 genotypes were phenotyped for plant growth and root characteristics in the bucket type container. The genotypes IHR 4517, IHR 3529, IHR 4501, IHR 4550, IHR 4491 and IHR 3241 with better root characteristics were identified.

Published: August 2023

Rose is a commercial flower crop widely grown across India. It is highly sensitive to salinity and alkalinity. In the process of identification of salt and alkalinity resistant rootstocks of rose cultivars, a survey was conducted in the rose growing areas of Uttar Pradesh (UP) and Rajasthan. Total of 28 representative surface soil samples were collected from rose fields of these regions, processed and analyzed for the soil quality parameters. Similarly water samples (20 samples) from the bore wells of these fields were collected and analyzed. The results revealed that most of the soils of rose growing fields in UP were alkaline (pH >8.0) with normal salt content (electrical conductivity, EC < 0.5 dS m-1). Many of these soils also had higher bicarbonates (> 3 meq 100 g-1). In case of Rajasthan, few samples had higher pH, EC, chloride (>2 meq 100 g-1) and bicarbonate contents. Exchangeable sodium percentage (ESP) of UP and Rajasthan samples ranged from 5.21-20.7% and 2.94-24.9%, respectively. In case of water parameters in these areas, pH was slightly in alkaline range, EC of some of the samples were high (>1 dSm-1). Sodium content was slightly higher than other cations. Soluble sodium percentage (SSP) of water samples was also slightly higher than normal range (0-50%). Few samples had slightly higher chloride above the threshold limit. From the results, it is concluded that soil and water quality of the rose growing areas of UP and Rajasthan is marginal and proper management/reclamation measures need to be carried out for sustaining the production system.

Assam lemon [Citrus limon (L.) Burm.], an indigenous lemon cultivar of Assam, is widely cultivated in warm southern slopes of the Himalayas in North-Eastern India. Since this cultivar of lemon is having a prominent trait of bearing fruits in several flushes throughout the year, it is essential to provide sufficient nutrition for obtaining optimum yield with good quality fruits. In the current experiment, a randomized block design having twelve treatments with three replications was followed to find out the response of lemon fruit yield and quality to foliar application of micronutrients during the year 2019. Among all, the treatment ZnSO4 (0.2%) + FeSO4 (0.2%) + Borax (0.2%) + CuSO4 (0.2%) gave the best performance in improving the yield and quality of fruits. The highest number of fruits per plant at the time of harvesting (73), yield per plant (11.5 kg), fruit fresh weight (158 g), fruit length (9.60 cm), fruit diameter (5.80 cm), juice content (152 mL/fruit), TSS (6.40 °B), ascorbic acid (49.10 mg/100g), total sugar (6.30%), reducing sugar (3.90%), non-reducing sugar (2.40%) with lowest titratable acidity(3.13%) were obtained which revealed that the yield and fruit quality of lemon depends on the application of different micronutrients.

Crop duration of the cultivated Pleurotus spp. is 45 to 50 days. P. djamor isolate woody-1 was collected as natural selection and was found to be short cropping duration variety with total cropping duration of 30 days but it is less palatable. It produced very thin, loose and non-rhizomorphic mycelia appearing light white color. Whereas, other commercial Pleurotus varieties such as P. florida and P. djamor MDU1 are long crop duration varieties and palatable producing thick, compact and rhizomorphic mycelia with bright white color. Co-segregation of non-rhizomorphic mycelial phenotype and short cropping duration trait of P. djamor woody- 1 in hybrid progenies was evaluated. Hybrid strains viz., H2W12 and H2W14 have thin, loose and non-rhizomorphic mycelium and they produced primordia in 9-10 days after spawning with total cropping duration of 29-32 days. Whereas, hybrid strain namely Pf1W2 has thick, compact and rhizomorphic mycelial phenotype and it produced primordia in 20 days after spawning with the total cropping duration of 47 days. This study indicated that genes governing short cropping duration and non-rhizomorphic mycelial pattern were tightly linked and co-segregated in the progenies. Thus, non-rhizomorphic mycelial phenotype of P. djamor woody1 can be used as a phenotypic marker for selection of hybrid cultivar having short cropping duration with other desired agronomic traits in future breeding strategy.

Mushrooms were considered as “Objects of mystery” by the primitive man, and were realized as food much before civilization. Mushrooms have been variously used in different cultures from being priced as “Food of Gods” in the Roman culture to tools of psychological sedation for the Mexican warriors. Most of the edible mushrooms are saprophytic growing on decomposed organic plant matter. Mushrooms play varied and important roles in human nutrition and health. They are unique nutrition dense vegetables with quality high protein, very low fat, zero cholesterol, low carbohydrates, low glycemic index, high fiber, good cardiac friendly sodium to potassium ratio and some unique bioactive compounds like ergothioneine and polysaccharides. These unique nutritive properties of mushrooms make them a recommended food for diabetics, body weight management, hypertension and cardiac well-being. The concept of selenium rich mushrooms for slowing down the progress of AIDS has been gaining importance in the recent years. Apart from being a healthy vegetable, the unique lignocellulosic waste-based production system of mushrooms makes them the most ecofriendly zero waste green technology with immense environmental benefits (Gupta et al., 2004, Jain et al., 2014 and & Pandey et al., 2014). Despite many environmental and nutritional benefits; mushrooms yet have not become a part of daily nutrition in the Indian diet and the per capita consumption still remains very low at 70 grams per annum. There is a need to educate and enhance the awareness among the people about the nutritional and health potential of mushrooms. There is also the need to draw the attention towards integrating mushroom technology in successful agro-residue management programs, livelihood programs, national nutrition programs and women empowerment and rural development schemes which ultimately culminate in providing better daily nutrition.

Jasmine occupies predominant position among the flower crops in India in terms of area, production and productivity. The demand for jasmine flowers is growing day by day owing to its wide range of uses and there is a pressing need for improving the crop by exploring strategies to evolve diverse genotypes. The present study focuses on the hybridization of Jasminum spp with the objective of introgression of desirable traits that would aid in creation of wider genetic variability. Pollination is the basis in any hybridization programme. The main aim of this research study was to determine the suitable pollination methods among self, open and cross pollination and to assess the effect of the pollination methods on the fruit set and fruit characteristics. The results of the study revealed that the overall response of J. auriculatum was found effective with maximum fruit set percentage. J. auriculatum cv Parimullai yielded the highest fruit set of 76.43% under open pollination and the least fruit set rate of 2.14% under self-pollination. Among the possible cross combination involving J. auriculatum and J. grandiflorum cultivars as seed parents with various pollen parents, J. flexile showed considerable results. Cross combination of J. auriculatum x J. flexile recorded maximum fruit set revealing best cross compatibility while crosses involving J. sambac resulted in no fruit set indicating the prevalence of fertilization barriers that hinder hybridization.

Late blight (Phytophthora infestans) is one of the devastating diseases of tomato worldwide. Field trial was carried out in Kharif 2019 and 2020 in Hesaraghatta, Bengaluru, Karnataka, India, to estimate yield loss due to late blight and to assess extent of protection in resistant genotype during late blight epiphytotics. Yield loss was calculated as per cent difference in yield between fungicides treated and unprotected plots in three F1 hybrids NS501, Arka Rakshak, both susceptible genotypes and Arka Abhed, a resistant genotype. Over two years, average yield loss due to late blight was 79.47 per cent in NS501, 75.53 per cent in Arka Rakshak and 12.84 per cent in Arka Abhed. With lower mean AUDPC values (147.22 in 2019 and 469.17 in 2020) and with low yield loss, Arka Abhed provided affordable protection against late blight. Our findings indicate late blight as an economically important peril to be considered for tomato yield loss coverage under insurance scheme in Bengaluru region. Arka Abhed hybrid can be cultivated to avert yield loss risk associated with late blight epiphytotics.

Published: August 2023

Nutrition and planting geometry are the two key factors affecting the production and quality of cut stems in chrysanthemum. The present investigation was undertaken to standardize the nitrogen nutrition and planting geometry for chrysanthemum var. “Yellow Star” cultivated for cut flowers. The data revealed the proportionate increase in plant height, chlorophyll content, days to bud appearance and days to 50% inflorescence anthesis and length of cut stem with increase in nitrogen dose and row spacing. However, flower diameter, number of flowers per stem, cut stem diameter, vase life, and water absorbed by cut flower decreased proportionately with increase in nitrogen dose and row spacing. Application of N@100 Kg ha-1 to chrysanthemum planted at 20x10 cm spacing produced cut stems of acceptable length, more number of flowers of bigger size and optimum postharvest longevity. The amount of nitrogen can be reduced to 1/3rd to grow cut chrysanthemums planted at twice the row spacing for longer cut stems of appreciable vase life.

During the process of updating horticultural records of this genus in Egypt, five problems were identified: lack of publications, lack of clarity between species, numerous errors of identifications, loss of earlier documented records of identity, as well as, the introduction and cultivation of new plants during the 19th Century added to the complexity of the problem. In this study, the taxonomic aspects of genus Mimusops, were thoroughly studied to identify the most reliable characters for taxon delimitation. Our assessment was based on morphological characters representing habit, leaves, petioles, flowering pedicels, buds, floral parts, fruit and seed. Fieldwork have revealed the presence of four species, of which Mimusops kummel and M. zeyheri are new records. The latter species is represented in Egypt by M. zeyheri var. laurifolia. This variety has been neglected by many authors. Additionally, Mimusops elengi L. was believed to be cultivated in Egypt, but no materials have been encountered that could confirm it. The specimens earlier identified as M. elengi actually belong either to M. kummel or to M. laurifolia. A detailed description of the genus and species with photographs, an identification key, and synonymy for each taxon are provided.
