Precision agriculture relies heavily on information technology, which also aids agronomists in their work. Weeds usually grow alongside crops, reducing the production of that crop. They are controlled by herbicides. The pesticide may harm the crop as well if the type of weed is not identified. To control weeds on farms, it is required to identify and classify them. A convolutional network or CNN, a deep learning-based computer vision technology, is used to evaluate images. A methodology is proposed to detect weeds using convolutional neural networks. There were two primary phases in this proposed methodology. The first phase is image collection and labeling, in which the features for images to be labeled for the base images are extracted. In the second phase, the convolutional neural network model is constructed by 20 layers to detect the weed. CNN architecture has three layers, namely, the convolutional layer, the pooling layer, and the dense layer. The input image is given to a convolutional layer to extract the features from the image. The features are given to the pooling layer to compress the image to reduce the computational complexity. The dense layer is used for final classification. The performance of the proposed methodology is assessed using agricultural dataset images taken from the Kaggle database.

Authors: Cao Thi Xuan Lien
Published: July 2023

Blended learning combines conventional classroom activities and online learning using a variety of educational technology tools, Learning Management System (LMS) included. The purpose of this paper is to examine the perceptions of EFL teachers and students about the use of LMS in blended courses. A mixed research method was adopted to collect data from 14 EFL teachers and 130 EFL students at a public university in central Vietnam through a web-based questionnaire and follow-up semi-structured interviews. The findings show that LMS offers EFL teachers and students a variety of benefits, including effective course organization and management, diverse teaching methods, flexible learning and teaching activities, and enhanced engagement and autonomy among students. However, the use of LMS in blended learning is perceived to be challenging because of technical issues such as unstable Internet connection and lack of needed devices, limited technical experience and skills, and a lack of e-learning pedagogy. Therefore, some recommendations were also proposed to improve the effectiveness of using LMS in blended learning.
A COHERENT WAY OF SAMPLING - A RULE TO BUILD INSIGHTS
Authors:   AI, Data Science & Machine Learning  Accenture Hyderabad, India, Leburi Sai Manasa
Published: July 2023

No companies can serve without data these days. With huge quantities of data being generated every alternate from business deals, client logs and stakeholders, data acts as an imperative pillar that drives various firms. In this scenario, it is impossible to study the entire data population to draw conclusions that can help the business. Inferences drawn from the samples are intended to be generalized to the population, and sometimes to the future as well. Sampling is a statistical process that is concerned with the selection of the individual observation. It helps us to make statistical hypotheticals about the population. Sampling ensures convenience, collection of intensive and exhaustive data, suitability in limited resources and better rapport and it permits you to draw decisions about very complex situations.

Authors: Rom Mitchell
Published: July 2023

This article provides a critical insight into some of the key challenges that are found in Indigenous education at university. It achieves this through sharing the storied experiences of non-Indigenous pre-service teachers, academics and myself. Overall, the study found, through storying methodology, a total of 11 key challenges across interrelated areas of the university. These areas included the university classroom and the broader institution, as well as education policy, specifically the Australian Professional Standards for Teachers (APST) 1.4 and 2.4 by the Australian Institute for Teaching and School Leadership (AITSL). This paper will provide an in-depth insight into three key classroom challenges (1, 2 and 4). It will not address key institutional or policy challenges. Ultimately, this paper will argue that some schools in Queensland need to place a greater value on the inclusion of Indigenous knowledges and perspectives. A practical recommendation is also offered in this article to further strengthen Indigenous education at university.

Published: July 2023

Background: The increase in stunting continues to occur in this world, including in Indonesia. the need for the cooperation of various interests to reduce stunting interventions. Various studies have shown that stunting is a lack of nutrition caused by a low household economic structure.
Aim: This study aims to determine the management of improving household economic structure as an effort to overcome stunting with case studies conducted on stunted households in Kupang Regency, TTS Regency, and Manggarai Regency.
Method: This study uses a qualitative method. Data obtained through documentation techniques.
Findings: The results of this study indicate that the management of increasing the household economic structure must be carried out jointly and cannot be carried out by only one sector. Based on several studies, the cause of stunting is a lack of nutrition. Malnutrition is caused by a lack of household welfare, and household economic welfare is caused by low education. So that the main source is education which is still low. Thus, the management of improving the household economic structure needs to start with improving education in Kupang, TTS, and Manggarai districts.

Authors: Lekhak Bindeswar Prasad
Published: July 2023

In the realm of development economics, foreign aid and economic development are interconnected concepts, both in theory and practice. Education, a fundamental human right, plays a pivotal role in shaping human capital and driving economic progress. With this in mind, the primary objective of this study is to explore the relationships between education aid and the various levels of schooling, namely primary, secondary, and tertiary, in developing countries. The effect of the primary, secondary, and tertiary level education aid of fifty developing countries with 19 years of panel data was investigated to determine the relationship with Primary Completion Rate, Secondary School Net Enrolment Rate, and Tertiary Gross Enrolment Rate, respectively. The study used the system GMM (One-step GMM and Two-step GMM). The findings suggest that a statistically significant relationship exists between education aid and various levels of education, and education aid effectively enhances the education outcome in developing countries. The findings also underline the importance of establishing sound economic foundations, addressing corruption, maintaining optimal Pupil-Teacher Ratio, and emphasizing female teachers. These factors collectively contribute to fostering an enabling environment for enhancing education outcomes in developing countries.
Language Contact in Bangladesh
Authors: Awal Abdul
Published: July 2023

This paper explores the significant diversity in Bengali, the predominant and official language of Bangladesh, primarily resulting from language contact, a prevailing concept in sociolinguistics. This paper scrutinises the historical influence of language contact on the evolution and development of Bengali from a sociolinguistic standpoint. Specifically, it traces the chronology of contact languages and the periodization of Bengali in Bangladesh. The author presents an overview of the current state of language contact in Bangladesh, considering influences from online media, virtual communication, and globalisation. The paper also critiques the limitations present in the existing literature on Bengali’s periodization. It further elucidates the intricate connection between language contact and the changes in the Bengali language. The study utilises a qualitative method, drawing from diverse sources such as academic articles, books, newspapers, public records, statistics, historical documents, and biographies, to deduce initial findings about the causes and impacts of contact languages in Bangladesh. One central theme is the examination of significant changes in Bengali resulting from contact languages. The paper seeks to investigate the sociolinguistic chronological history of contact languages in Bangladesh. Following an interpretivist paradigm, it views linguistic contact as a socially constructed reality, embodying multiple perspectives within Bangladesh. Besides underscoring the influence of virtual language contact on digital platforms in Bangladesh, the findings emphasise the crucial role of contact languages in the development and maturation of the Bengali language.

In this work generalized supplemented semimodules are defined which generalize generalized supplemented modules. We investigate some properties of these semimodules. We show that the finite sum of GS-semimodules is GS-semimodule. We also define WGS-semimodules and proved that a semiring S is semilocal if and only if every finitely generated semimodule is a WGS-semimodule. Furthermore, we prove that if A be a semimodule as well as Rad(A)≪A. Then A is a WGS-semimodule if and only if A/Rad(A) is semisimple.
Empirical Case Studies on the Economic and Political Effects of the Belt and Road Initiative in Pakistan, Kenya, Sri Lanka, and Montenegro
Authors:   Comparative Political Institutions of the World, Mark P. Jones, Dunsby Isabella Jia
Published: July 2023

The Belt and Road Initiative has had a wide range of effects on participating countries. Its economic and political implications continue to raise important questions about China’s global influence using soft power. The BRI initiative has the potential to accelerate globalization and boost domestic economies. This paper analyzes the BRI’s involvement in three geopolitical regions (Asia, Africa, and Europe) by examining the economic and political impacts of four internal BRI projects: Chinese Pakistan Economic Corridor (CPEC), Mombasa-Nairobi Standard Gauge Railway, International Hambantota Port, and Bar Boljare Highway. The analysis is conducted by examining different outcomes of each project using a predetermined rubric which considers economic (GDP, FDI, trade, social welfare, debt sustainability) and political (internal power, international relations) implications. The analysis of all four case studies conclude that Kenya and Pakistan have benefited from their respective BRI projects, while Sri Lanka and Montenegro’s BRI projects appear unsuccessful due to lack of strategy involved in their placement/creation. Furthermore, all four countries suffer from varying amounts of debt distress as a result of Chinese BRI investment. Lastly, the BRI provides outlets for Chinese involvement in internal power (especially in the case of Kenya and Sri Lanka), as well as strengthens Sino relations with participating countries.

Fabrication and characterizations of high density Si3N4 - ZrO2 ceramics
Authors: TRAIPANYA Kamol , WASANAPIARNPONG Thanakorn , MONGKOLKACHIT Charusporn
Published: July 2023

Silicon nitride and zirconia were mixed with SiO2, MgO, Y2O3 as sintering additives and pressureless sintered at 1650℃ in N2 atmosphere for 2 h. The XRD results showed a-Si3N4 was partially transformed to b-Si3N4 with 3:3:5 weight ratio of SiO2 : MgO : Y2O3. However, at 5 wt% of ZrO2 addition promoted phase transformation of a-Si3N4 to b-Si3N4 while 35 wt% of ZrO2 completely transformed to b-Si3N4 phase. Si3N4 has a lower density than ZrO2, bulk density of samples increases in correlation with the amount of ZrO2. Because there was no difference in hardness and flexural strength between sintered Si3N4 samples with hardness of 13.41 GPa and 648.13 MPa along with increasing ZrO2 variation up to 55 wt%. Furthermore, with 75 wt% ZrO2, the hardness was reduced to 10.57 GPa and the flexural strength decreased to 208.16 MPa. SEM images of Si3N4 samples demonstrated the dense microstructure and 5 wt% ZrO2 showed homogeneous ZrO2 distributed among the Si3N4 grains. As a result, the hexagonal rod-like form of b-Si3N4 is clearly visible in 75 wt% ZrO2. Therefore, Si3N4 with ZrO2 can be sintered with the homogeneous microstructure of the a-Si3N4 to b-Si3N4 transformation and tolerable mechanical properties vary with ZrO2 content.

Durante el año 2007 la Biblioteca Nacional realizó un concurso de becas de investigación al que llamó “Félix de Azara”, homenajeando al viajero y naturalista español que dejó registros literarios y cartográficos de la región y que, en los tramos finales de la vida colonial, realizó una distribución de tierras en la frontera norte de la Banda Oriental, secundado por el entonces capitán de Blandengues José Artigas. El concurso convocó a proyectos orientados a recopilar y analizar los distintos modos de conocimiento de la región durante el siglo XIX: imágenes, mapas, descripciones, historias, relatos de viajeros. Un jurado integrado por Susana Cella, Patricia Funes y Julio Vezub seleccionó cinco proyectos para ser financiados, referidos al estudio de materiales que existen en los fondos patrimoniales de la Biblioteca.

Diego Galeano, en el marco de este concurso, escribió este libro sobre la cultura policial durante el siglo XIX. Si el tema es original no menos es el abordaje, que lejos de pensar los textos, discursos, imágenes, como indicios de una disposición unívocamente represiva, los trata como signos de una zona mixta y en debate, en la que no siempre es sencillo diferenciar los agentes de la ley de los cultores de la mala vida. Se puede leer este libro como una arqueología a través de la cual surgen los restos de una ciudadela antigua, aquella donde la vocación del pesquisa se articulaba con la disposición a satisfacer el deseo de conocimiento de las zonas oscuras de la urbe por parte del público.

Published: July 2023

SETTING: Tertiary level hospital in Lusaka, Zambia.OBJECTIVE: To measure concordance between Xpert® MTB/RIF Ultra (Ultra) results of stool with and without transport media, and compare Ultra results from the two stool processing methods to Ultra and
culture results using gastric aspirates (GA).DESIGN: This was a cross-sectional study collecting stool and GA from children 0–5 years presenting with signs and symptoms of TB. Stool was processed for Ultra testing by two methods: the Simple-One-Step (SOS) on an aliquot of
stool and PrimeStore® MTM Molecular Transport Medium (PS-MTM) using a stool swab.RESULTS: A total of 114 children (median age: 17 months, IQR 7–30) provided both a stool and a GA sample. Stool Ultra results processed using the PS-MTM method showed high concordance
with stool Ultra results processed by the SOS method, with only 1/114 discordant results. Concordance with GA Ultra was high as well, as 9/13 Mycobacterium tuberculosis (MTB) cases detected were identified by all three methods.CONCLUSION: Ultra results from stool swabs collected
using PS-MTM were equivalent to results from stool using the SOS method and GA. Given that PS-MTM inactivates MTB and stabilises DNA without cold chain, using it for stool has the potential to increase access to a TB diagnosis for children in underserved areas.
Quorum Sensing in Pseudomonas aeruginosa: Mechanisms, strategies, and a novel inhibitor
Authors: Raj Aditya , Kirienko Natasha
Published: July 2023

Pseudomonas aeruginosa, an opportunistic life-threatening bacterial pathogen, uses quorum sensing signals to modulate the expression of virulent genes. These bacteria exhibit high levels of antimicrobial resistance, which reduces the effectiveness of current antibiotics, highlighting the need for treatments that do not induce selective pressure. A comprehensive understanding of the factors inhibiting quorum sensing in P. aeruginosa is necessary to design an alternative therapeutic strategy for long-term treatments that do not function by traditional bactericidal or bacteriostatic mechanisms. This manuscript is a literature review highlighting a novel, naturally occurring molecule with a high potential to inhibit quorum sensing and virulence. It covers methods by which the anti- virulent nature of this molecule can be verified and how it can be used as a supplement to traditional antibiotics and as a possible new stand-alone medicine.

Authors: Nowacek Jackson D.
Published: July 2023

Population modeling is an established, effective tool for assessing the effects of environmental conditions on a specific population. The model this paper outlines is based on the Green Sea Turtle (Chelonia mydas) population of the Northern Great Barrier Reef. The model shows the effects of variable temperature, light, nutrients, predation, and availability of food (seagrass) on the long-term health of the population. Several tests were run by adjusting variables such as initial seagrass levels, seagrass threshold, mortality rates, nest temperature, light, and nutrients. The model showed biologically and ecologically plausible reactions to each variable change.

O objetivo do presente estudo é refletir sobre epistemologias e sustentabilidade na Administração, no contexto colonial do antropoceno. As epistemologias oferecem formas particulares de abordar o conhecimento que, por meio das lentes teóricas dominantes, se vê miragens de "verdades" que apaziguam as muitas turbulências ambientais que são enfrentadas empiricamente. Argumentamos que a ecologia-mundo capitalismo moldou a ciência moderna e vice-versa, bem como as relações por meio das interações entre os primeiros capitalistas e os "selvagens". Defendemos que os debates sobre as questões epistemológicas e posicionamento de outras mentes em campos políticos da área científica são urgentes, a fim de ampliarmos os espaços para outros conhecimentos que se distanciam das restrições epistemológicas coloniais.

Background and purpose: Flavonoids are a group of phytochemicals found abundantly in various plants. Scientific evidence has revealed that flavonoids display potential biological activities, including their ability to alleviate inflammation. This activity is closely related to their action in blocking the inflammatory cascade and inhibiting the production of pro-inflammatory factors. However, as flavonoids typically have poor bioavailability and pharmacokinetic profile, it is quite challenging to establish these compounds as a drug. Nevertheless, progressive advancements in drug delivery systems, particularly in nanotechnology, have shown promising approaches to overcome such challenges. Review approach: This narrative review provides an overview of scientific knowledge about the mechanism of action of flavonoids in the mitigation of inflammatory reaction prior to delivering a comprehensive discussion about the opportunity of the nanotechnology-based delivery system in the preparation of the flavonoid-based drug. Key results: Various studies conducted in silico, in vitro, in vivo, and clinical trials have deciphered that the anti-inflammatory activities of flavonoids are closely linked to their ability to modulate various biochemical mediators, enzymes, and signalling pathways involved in the inflammatory processes. This compound could be encapsulated in nanotechnology platforms to increase the solubility, bioavailability, and pharmacological activity of flavonoids as well as reduce the toxic effects of these compounds. Conclusion: in Summary, we conclude that flavonoids and their derivates have given promising results in their development as new anti-inflammatory drug candidates, especially if they formulate in nanoparticles.
Effect of sintering temperature and time on corrosion characteristics of aluminum matrix composites
Authors: Mahdi Sahib M. , Ghalib Lubna
Published: July 2023

Aluminum matrix composites outperform traditional alloys in terms of mechanical properties and corrosion resistance. Silicon carbide is the main reinforcing material in aluminum-based composites that have developed rapidly in recent years. In this investigation, aluminum-silicon carbide composites were prepared through powder metallurgy with 10 and 20 wt.% of silicon carbide reinforcement. The influence of the SiC content, sintering temperature, and sintering time on the corrosion behavior of prepared Al-SiC composites in 0.5 M hydrochloride acid solution was assessed. The surface microstructure was characterized by scanning electron microscopy with energy dispersive analysis and X-rays. The experimental results demonstrated how the sintering parameters can affect the corrosion characteristics of sintered samples. The electrochemical analysis curves showed that when increasing the sintering temperature and sintering time, there is a possibility of self-repair of damaged passive film on the surface while further reinforcing of the composite with silicon carbide prevents penetration of chloride ions. The SEM images and EDS analysis of composite surfaces after being corroded in 0.5 M HCl revealed that increasing the sintering temperature and prolonging the sintering time reduce the pitting corrosion of composites.

Published: July 2023

Introduction: Chronic rhinosinusitis is an important disease of the upper respiratory system which substantially reduces patient quality of life and the methods of symptomatic treatment are tremendously limited.

Aim: The aim of this study was to evaluate the next therapeutic option which is a combination of respiratory rehabilitation and subterraneotherapy.

Material and methods: The study covered 57 patients of whom 15 were men and 42 women. The average age of patients was 60 +/- 10.87 (standard deviation). 44 patients finished 15 days of therapy which covers full-time treatment. The average age of these patients was 59.7 +/- 11.6 (standard deviation).

Results: In the study group, there was a statistically significant reduction among all analyzed symptoms of chronic rhinosinusitis. The general severity of symptoms decreased from 5.66 cm to 2.57 cm (p < 0.001), blockade/congestion of the nose from 5.49 to 2.23 cm (p < 0.001), anterior nasal discharge from 5.33 cm to 2.5 cm (p < 0.001), posterior nasal discharge from 6.04 cm to 2.71 cm (p < 0.001), facial pain/pressure from 3.43 cm to 1.45 cm (p < 0.001), headache from 3.73 cm to 1.19 cm (p < 0.001) and reduction or loss of smell from 4.17 cm to 1.94 cm (p < 0.001).

Conclusions: Such a notable improvement in all analyzed symptoms led us to conclude that respiratory rehabilitation, especially such conducted in adequate climatic conditions, should be a valuable therapeutic option in the symptomatic treatment of patients with chronic rhinosinusitis.

Published: July 2023

Renal cell carcinoma accounts for about 2-3% of all malignancies. It is characterized by a high frequency of metastases, which are most often observed in the lungs, bones, liver, brain and regional lymph nodes. Literature highlights the rare occurrence of renal cancer metastases to the head and neck, even though it is the third most common cancer that metastasizes to the head and neck.Below we present a case report of metastases of clear cell carcinoma from a kidney to the organs of the head and neck. The analysis was carried out retrospectively based on medical records of a patient hospitalized at the Department of Otorhinolaryngology, Head and Neck Surgery of the Medical University of Warsaw in the years 2009-2019. We describe an 81-year-old man after left-sided nephrectomy due to clear cell carcinoma, with numerous distant metastases, who was diagnosed with metastases to the left submandibular salivary gland 8 years after primary surgery, followed by a diagnosis of metastasis to the right submandibular salivary gland 3 years later. The patient underwent 2 radical procedures to remove the submandibular salivary glands. Due to the presence of lung metastases, treatment with a tyrosine kinase inhibitor was also implemented.

Published: July 2023

Introduction: Myoepithelioma (ME) is a benign tumour in 40% of cases located in the parotid gland, accounting for <11.5% of all salivary gland tumours. Myoepitheliomas arise from myoepithelial cells, which are present in major and minor salivary glands, but also lacrimal glands, breasts, and sweat glands. They are seen more often between the fourth and fifth decade of life, without sex predominance. Patients mainly complain about painless, slowly growing mass. MEs in CT are characterized as well-circumscribed small, unilocular, round tumours with smooth or lobulated contours; they may contain enhancing nodules and non-enhancing areas and exhibit homogeneous signal intensities or densities based on MRI. Deep lobe parotid tumours may occasionally grow along the stylomandibular tunnel into the parapharyngeal region resembling dumbbell shape. Tumours of the parapharyngeal space are rare and account for 0.50.8% of all head and neck tumours. Patients have an intraoral mass or asymmetry of the palate, with difficulties in swallowing or phonation. Operative removal with capsule preservation is the treatment of choice. The approach depends on the size of the tumour: cervical, transoral, transparotid, mandibular osteotomy approach or a combination of these. MEs may be locally aggressive, especially in long-standing tumours or in tumours with multiple recurrences.

Case report: The authors present two cases of myoepithelioma in the parapharyngeal space.

Authors: Przekop Zuzanna , Milewska Magdalena , Szostak-Wegierek Dorota
Published: July 2023

The occurrence of dysphagia and malnutrition in patients with head and neck cancers is associated with sequelae that negatively affect the treatment process and its effectiveness. Therefore, it is important to perform screening of dysphagia and malnutrition in this group of patients. Screening tests should be quick to perform, easy to use, and cost-effective. The methods used should be validated on the target group of patients. For patients with head and neck tumours, such validation is provided by four dysphagia screening questionnaires and nine malnutrition screening questionnaires.

 Introduction: COVID-19 is a disease caused by pathogenic -coronavirus. As a relatively new disease, diagnosis of COVID-19 is highly problematic and because of non-specific symptoms the infection must be confirmed with molecular tests.

 Aim: Evaluation of the most common COVID-19 symptoms and statistical analysis of obtained data in order to confirm significant correlations between symptoms and age and sex of the examined patients.

  Material and methods: A questionnaire has been carried out among 751 patients of Center for Blood Donation in Gdansk and the Department of Otolaryngology in Gdansk. The patients were convalescents after SARS-CoV-2 infection. The presence of virus was confirmed by a positive PCR test of RNA of the SARS-CoV-2 virus of each patent. The study has been carried out since the beginning of the presence of COVID-19 in Pomerania region till April 2021.

 Results: Results of the questionnaires presented the most common general and otolaryngological symptoms of COVID-19. Collected data was statistically analyzed. Patients were divided according to age and sex. 30.2% of patients had severe clinical course of infection, 69.8% had mild clinical course. The most common general symptom associated with SARS-CoV-2 infection was fatigue, which was more common among women. Other common symptoms were loss of smell and taste, also more common among women, and muscle and joint pain. The most common other otolaryngological symptoms were sore throat and vertigo, all more frequent in men.

 Conclusion: The study presents the correlation between incidence of COVID-19 disease symptoms and age and sex of patients. Fatigue, loss of smell and taste and muscle and joint pain were the most common symptoms of the infection. Presented data highlights the meaning of further research on COVID-19 symptoms.

Published: July 2023

To improve nut yield and soil fertility, a study on nitrogen management was taken up on eight year old almond (Prunus dulcis L.) grafted plants of commercial variety Waris spaced at 3.5 x 3.5m and treatments were imposed in 2009. The results of long term experimentation clearly indicated that maximum mean nut yield (3.16 kg/tree and 2.71 tonnes/ha) was recorded with the application of 40 tonnes/ha FYM followed by 100% RDF + 10 tonnes/ha FYM (2.83 kg/tree and 2.41 tonnes/ha) and minimum (1.61 kg/tree and 1.73 tonnes/ha) was recorded in control plots (No fertilizer). The fertility status of soil also improved by application of organic and inorganic fertilizers, the available nitrogen, phosphorus and potassium content (46.13, 26.8, 38.67%) were estimated with the application of 40 tonnes FYM/ha in almond variety Waris under north western Himalayan region of India.

The present study was conducted to assess the effect of water deficit coupled with salt stress on physiological traits and stress tolerance mechanisms of rice (Oryza sativa L.) varieties differing in salt tolerance. Two salt tolerant (CSR 10 and CSR 36) and two salt sensitive (IR 29 and Pusa 44) rice varieties were evaluated in different combinations of controlled water deficit coupled with salt stress conditions. The salt tolerant variety CSR 10 has shown the best morphological or phenological growth performance; while IR 29 performed the worst in terms of reduction in growth at 25 and 50% water deficit. At 50 and 100 mM NaCl along with 50% water deficit, 80% plants of IR 29 could not survive. Variety CSR 10 exhibited maintenance of higher total chlorophyll concentration (ChlT), relative water content (RWC), gas exchange characteristics and chlorophyll fluorescence attributes with lower membrane injury (MI) and thus ultimately showed better stress tolerance than other varieties.

Published: July 2023

The present experiment was carried out with an objective to find out the effect of surfactant on the efficacy of insecticides, because the use of insecticides for the control of onion thrips (Thrips tabaci Lindeman) is relatively less promising due to onion leaf pattern and texture. The minimum thrips population (6.48/plant) and thrips incidence (19.57%) were recorded at 15 days after spray in the fipronil 5 SC at 2 ml + surfactant at 0.5 ml/l of water, followed by lambda cyhalothrin 5 EC at 2 ml + surfactant at 0.5 ml (8.85/plant and 21.51%, respectively). While, imidacloprid 17.8 SL alone at 0.4 ml/l of water showed higher thrips population (21.78/plant) when compared to other treatments and which was found at par with untreated control. The efficacy of insecticides was significantly increased by addition of surfactant from 14.60 to 33.20 and 7.52 to 23.10% in minimizing the number of thrips/plant and thrips incidence %, respectively. The minimum thrips damage severity (1.36) and maximum bulb yield (254.83 q/h) with highest cost benefit ratio (1:6.84) was recorded in fipronil 5 SC at 2 ml + surfactant at 0.5 ml/l of water followed by lambda cyhalothrin 5 EC at 2 ml + surfactant at 0.5 ml (1.62, 249.50 q/ha and 1:6.14, respectively). Fipronil 5 SC and lambda cyhalothrin 5 EC without surfactant showed intermediate thrips damage severity (1.68 and 1.96, respectively), bulb yield (241.53 and 238.52 q/ha, respectively), and cost benefit ratio (1:5.68 and 1:5.26, respectively). The insecticides along with surfactant reduced the thrips damage severity (10.46–19.05%) and increased the bulb yield (1.97–5.51%) in different treatments when compared with the insecticides without surfactant. Along with insecticides the use of surfactant could be highly desirable.

A field experiment was conducted during rabi 2011 and kharif of 2012 to estimate the magnitude of heterosis and heterobeltiosis for fruit yield and its attributing traits in brinjal. Ten indigenous parental lines of brinjal were selected and crossed in a half diallel-fashion and the resultant 45 F1 hybrids (excluding reciprocals) along with their parents were evaluated for yield and its component traits in a randomized block design (RBD) with three replications. The observations were recorded on five randomly selected plants per replication for each genotype on eight important characters, viz. days to first flowering, days to 75% flowering, days to first fruit harvest, number of fruit clusters/ plant, fruit width (cm), number of fruits/plant, average fruit weight (g) and average fruit yield/plant (kg). Relative heterosis and heterobeltiosis provides an idea about the nature of gene actions involved in the genetic control of the concerned trait. Relative heterosis besides epistatic effects also indicate the presence of dominance effects (intra allelic interaction), while heterosis is indicative of over dominance. Analysis of variance and result reveals highly significant difference for almost all the characters. The heterosis and heterobeltiosis ranged from 23.33 to 197. 80% and from 21.06 to 166.03 %, respectively. The results of present investigation also revealed that the crosses P7 × P8 (PPC × Udaipur local) and P8 × P10 (Udaipur local and Pusa Bhairav) exhibited high degree of heterosis and heterobeltiosis for fruit yield and other yield attributing traits, viz. fruit weight, fruit width and number of fruits/cluster indicating the additive or synergistic effect of the component characters on fruit yield.
