A total 420 faecal samples were examined microscopically by using Stoll’s ova dilution technique from June to December 2020. The number of eggs per gram of feces was calculated and it ranged from 100-500.The study showed that 100% sheep were found to be infected with one or more species of parasites. Four types of parasites were identified. In grazing animals, stomach worm, Paramphistomum worm, Fasciola and install feeding, stomach worm and Trichuris were found. The prevalence of parasites in grazing on 0 day was stomach worm 20%, Paramphistomum worm10% whereas in stall feeding it was stomach worm 15% and Trichuris 10%. In 15 days, in all grazing animals stomach worm was 10% and Paramphistomum worm 10% whereas in stall feeding it was stomach worm 5%. On 30th day, in grazing animals, stomach worm 15%, and Paramphistomum worm 10% were present, whereas in stall feeding it was stomach worm 10%, and Paramphistomum 10%. The highest prevalence of stomach worm was 20%, whereas Paramphistomum was the lowest with 10% as seen ingrazing animals. Stomach worm with 15% was the highest and theTrichuris with 10% was the lowest in stall feeding animals. Prevalence of parasites increased with the flock size on 0 day and ivermectin injection reduced the prevalence in 15 days and later it increased after 30 days of interval. The prevalence was higher in char area (35%) than the hilly area (15%). The sheep were more affected in grazing (25%) than stall feeding (20%). In conclusion, the use of ivermectin injection reduced the prevalence of gastrointestinal parasites up to one month in sheep.\u0000SAARC J.

Ten genotypes of summer growing chilli including one released variety viz., BARI morich-2; one advanced line viz., SRC- 517 and eight local cultivars viz., IAH-160, IAH-164, AHM-206, AHM-217, AC-63, AC-312, RAI-67, and RI-1(6) were characterized with a view to explore genetic diversity within these genotypes based molecular markers. Using eight microsatellite (SSR) primers across 10 genotypes, a total of 30 alleles with an average number of 3.75 alleles per locus were found. The number of alleles detected varied form three (CAMS-864, CAMS-880, CAMS-885) to five (CAMS-647). The allele size ranged from 160 (CAMS-075) to 289 bp (CAMS-864). All most all sets of primers showed high polymorphism (PIC value ≥0.6) except CAMS-880 and CAMS-885 which suggesting the greater genetic diversity in the genotypes. Gene diversity ranged from 0.460 (CAMS-885) to 0.740 (CAMS-647) and the highest and lowest value of Shannon's Information Index was registered in the same locus with their average value of 1.174. Higher level of genetic differentiation (0.971) and lower level of gene flow value (0.007) which were indicative of the presence of diversity among the genotypes.

The water table goes down to the level of 50 cm below soil surface during dry periods and soil pH falls to 3-4 causing acid sulphate condition. Hitherto several efforts have been made to ameliorate the paddy lands but no any economical solution is obtained. The National Science Foundation project to find out the feasibility of using natural hydraulic forces to increase water table to keep the acid sulphate forming minerals at bay and to cultivate rice in these paddy lands. Water table fluctuation in relation to water level in the drainage channel was studied over one year and there was found a very high correlation (r2=0.985) indicating a possibility of increasing water table by heading up water in the channel. Simulated pot experiment showed that increasing water table to 15 cm below soil surface allows rice to grow effectively, showing plant survival of 112 (53%) compared to 28 (15%) plants in control. Recorded plant height of Bg. 357 variety was 35 cm compared to 22 cm in different treatments and control, respectively. Soil pH also increased to a value closer to 6.0 in the treatment which is conducive for rice cultivation. However, the low values of plant survival and plant heights were due to unusual extreme low rainfall in 2020/21 Maha season compared to 10 years’ average.\u0000SAARC J.

The objective of this article is to identify the factors influence biogas adoption in rural households. The study aimed to look at the policy framework that needs to be put in place to promote biogas adoption as a cooking fuel in the study region. This study collected primary data by interviewing 118 respondents with a structured questionnaire (78 biogas users and 40 non-users) during July-August 2021. Respondents were women who cook for their families regularly. This paper based on a cross-sectional analysis of nine socio-economic and demographic parameters that may influence biogas uptake in Western Bangladesh. The dependent variable, biogas cooking fuel adoption status, was modeled as a dichotomous variable. To evaluate the relationship between independent variables with the dependent variable (biogas user and no-user), bivariate descriptive analysis (t-test for continuous data and chi-square test for categorical data) was performed. Then, a binary regression model was chosen to determine the adjusted effect of independent variables on biogas adoption decisions. The study found that the demographic factors such as income status of the women, education of household head, family size and total family income significantly and positively influence biogas adoption decisions. Contrary to the hypothesis, access to internet and total land area owned by the family show negative relation with biogas cooking fuel adoption status of the household. The outcome of this research added evidence to support energy policy with giving emphasis on subsidy, and adult education in rural areas.\u0000SAARC J.

All characters recorded higher PCV value over GCV thereby indicating the influence of environmental factors in their expression. High heritability observed in all the characters studied and high heritability coupled with high genetic advance found in the parameters viz. number of pods per plant, average pod weight, 100 seed weight and pod yield per plant. Correlation coefficient analysis showed pod yield had significant and positive correlation with number of pods per plant, pod length, average pod weight and 100 seed weight. Path analysis revealed that maximum positive direct effect w.r.t pod yield per plant was brought about by the parameters viz. 100 seed weight, days taken to marketable maturity, number of seeds per pod, number of pods per plant, average pod weight, pod width and pod length hence, should be given more importance for genetic improvement to bring about an increase in overall production of french bean through enhanced pod yield per plant.\u0000SAARC J.

The plant characters such as leaf area, plant height, number of leaves plant-1, straw weight plant-1, absolute growth rate, number of fruits plant-1, individual fruit weight and fruit yield were not affected up to 6 leaves defoliation irrespective of seasons and genotypes. Interestingly, photosynthesis, nitrate reductase and reproductive efficiency increased with increasing defoliation levels. Morpho-physiological parameters and yield attributes were better in 3 and 6 leaves defoliated plants over the control with being the highest in 6 leaves defoliated plant, which resulting the highest fruit yield. Heavy defoliation not only reduced source sizes but also decreased total sink (fruits) causing lower fruit yields. The lowest morpho-physiological attributes and fruit yield was recorded in 12 leaves defoliated plants.

They aid in improving crop health and yields while lowering production costs and eliminating the usage of toxic chemicals. They are effective tools for creating new sustainable agricultural products. Several botanicals and microbial biopesticides have been identified, isolated, processed, and used to eliminate hazards caused by Coleopteran, Hemipteran, Dipteran, Lepidopteran, Hymenopteran, and Thysanopteran insects. Several species of botanicals such as Neem (Azadirachta indica A.), Chili pepper (Capsicum annuum), Garlic (Allium sativum), Moringa (Moringa oleifera), Clove basil (Ocimum gratissimum), China berry (Melia azedarach), bitter leaf (Vernonia amygdalina) etc. and microbes such as Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae, Baculovirus (nucleopolyhedrovirus (NPV) and granulovirus (GV) ), Steinernema carpocapsae, Nosema, etc. have been used as biopesticides. Because biopesticides are successful in managing insect pests and diseases while also being safe to humans and the environment, they must be manufactured in the country and made available to farmers.\u0000SAARC J.
