Arx at Oilseed Research Program, Sarlahi, Nepal. The experiment was laid out in randomized complete block design (RCBD) with 7 treatments viz. rice husk, rice straw, black polythene sheet, Lantana camara, living mulch, sawdust and control in three replications with fertilizer dose 20:40:20 NPK kg per hectare. The disease was scored in 1-9 scale and severity and AUDPC was calculated. In 2020, Lantana camara mulched plot showed significantly the lowest disease severity and the lowest AUDPC value (66.67% and 1556) followed by rice husk (70.37% and 1556) and black plastic (70.37% and 1611) mulched plot. Similarly in 2021, Lantana camara mulched plot showed significantly lowest disease severity and the lowest AUDPC value (62.96% and 1500) followed by rice husk (66.67% and 1574) and black plastic (66.67% and 1574) mulched plot. Significantly the highest pod yield was obtained in rice husk mulched plot (2.35 t/ha in 2020 and 2.07 t/ha in 2021) followed by living mulch treated plot (2.13 t/ha in 2020 and 1.84 t/ha in 2021). The highest disease severity (81.4% same as rice straw and saw dust mulched plot) with highest AUDPC value (1981) was observed in plot with no mulch during 2020 where as in 2021, the highest disease severity (77.78 same as plot with no mulch) with highest AUDPC value (1889) was observed in rice straw mulched plot. This study shows that organic mulches like rice husk could be better option for reducing disease severity with better yield in groundnut. \u0000Int. J. Appl. Sci. Biotechnol.

Phytophthora nicotianae is primarily found in tropical and subtropical regions and infects tobacco plants by producing zoospores that swim to root tissue and form cysts. Symptoms of black shank include root and crown rot, wilting, leaf chlorosis, stem lesions, and pith necrosis. Management strategies for black shank include cultural practices, chemical treatments, and host resistance. Chemical fungicides, such as metalaxyl or mefenoxam, oxathiapiprolin, and fluopicolide, can be used but there is a risk of fungicide resistance. Fusarium wilt is characterized by yellowing, drying, and death of leaves, leading to the death of the entire plant. Control measures for Fusarium wilt include plant resistance, cleanliness, crop rotation, nutrition, nematode management, and fumigation or biofumigation. The most successful control of Fusarium wilt has been through the use of resistant tobacco cultivars. The impact of rotation crops and resistant plants on the pathogen populations in the soil must be evaluated and soil pH and calcium levels may also impact the disease. The presence of the fungus in a field can last for several years without a vulnerable host.\u0000Int. J. Appl. Sci. Biotechnol.

The first step towards harnessing the potential of these landraces in crop improvement programs is to identify the amount of genetic variation present among them. This research aimed to evaluate 18 cucumber accessions collected from different regions of Nepal and assess their agro-morphological variation in terms of yield and yield-associated traits under polyhouse condition. A research trial was conducted using Randomized Complete Block Design with two replicates at the National Agriculture Genetic Resources Centre (NAGRC), Khumaltar in 2019. The accessions were characterized using various qualitative and quantitative descriptors, with six focusing on traits related to the fruits of the plant and three on phenology and morphology. The results revealed significant variations among the genotypes for all studied traits. Bhaktapur Local was an excellent genotype for recording yield and associated traits, like fruit dimension, number of fruits per plant and yield per plant, making it the most promising genotype, however, Genebank accessions, such as NGRC08671, NGRC07716 and NGRC08668 could be excellent choices for yield associated traits. Correlation analysis indicated a positive relationship between yield and fruit length, fruit width, and total number of fruits per plant, while vine length was positively correlated with the total number of fruits produced per plant. This study identified several genotypes with desirable traits for yield and yield-associated characteristics, which could be valuable in the development of high-yielding cucumber varieties with superior morphological and agronomic traits in the future. \u0000Int.

Soil samples were taken annually (2016 to 2020) after harvesting on a thickness of 0 and 20 cm. In each plot, thirteen (13) samples were taken. After quartering, one (01) representative sample from each plot was retained. The samples were analyzed by optical emission spectrometry at the Food Quality Control Center Laboratory (FQCCL) in Ndjamena. The determination of heavy metal concentrations revealed relatively low levels for Ni, Zn, Cu, Cr and Fe. These levels are generally lower than the reference values for all the plots. Geoaccumulation indices (Igeo) and Contamination factor (Cf) revealed pollution indices. Pb and Cd show contaminations in traditional plots. The correlations (P < 0.05) observed in our study area are positive and significant. This study shows that the use of chemical inputs are sources of soil contamination by heavy metals.\u0000Int. J.

During the study, 162 goat farms located in Ghiring and Baradi of Tanahun districts in Nepal were surveyed, and a semi-structured questionnaire was administered to each farm. Farmers in this region prefer integrating livestock raising with crop production. The majority of the farms surveyed kept indigenous Khari goats, either in pure flocks or through crossbreeding. The types of goat farming were commercial (8.02%), semi-commercial (29.01%) and subsistence (62.96%). The nature of management practices for goat farmers was intensive (70.99%), semi-intensive (14.81%) and free range (14.20%). Farmers grazed their livestock in different locations, including their own land (48.77%), forests (22.22%), and other places (29.01%). The selection of fodder species by farmers varied depending on the availability of different species in the mid hills, reflecting differences in their perception and preference. Among the top fodder species highly preferred by the farmer in summer season are Ficus cunia followed by Bauhinia longifolia, Ficus hispida, Castanopsis indica and Ficus auriculata. Fodder species highly preferred by the farmers in winter season are Litsea polyantha followed by Drepanostachyum khasianum, Shorea robusta, Terminalia elliptica and Mangifera indica. Goat production is an essential aspect of subsistence farming, providing both meat and cash income. Consequently, this study recommends promoting locally preferred tree fodder species and supplementing them with feed during different seasons, based on their availability and local preferences. Such strategies can help to improve goat production and support sustainable livelihoods for farmers in the region. \u0000Int. J. Appl. Sci. Biotechnol.

Combined application of chemical and biofertilizer can reduce chemical fertilizer and enhance the yield under limited fertilizer availability. A field experiment was carried out to assess the combined application of chemical and biofertilizer on the growth and yield of spring wheat at Rampur, Chitwan from November 2020 to April 2021. The experiment was laid out in strip plot design with four nitrogen and P2O5 levels (0, 50, 75 and 100% of recommended dose) in vertical plots and three biofertilizer application methods (not applied, seed applied and soil applied) in horizontal plots with three replications. The research results revealed significant interaction between nitrogen and P2O5 levels and biofertilizer application methods. The highest grain yield (4624.48 kg ha-1) of wheat was obtained with 100% levels of N and P2O5 with soil applied biofertilizer at par with 75% levels of N and P2O5 with soil applied biofertilizer (4457.54 kg ha-1). The total nitrogen uptake was higher in biofertilizer applied wheat as compared with no application of biofertilizer although statistically not significant. The yield increment in 100% and 75% N and P2O5 levels with soil applied biofertilizer over same level N and P2O5 with no biofertilizer application were 10.96% and 29.60% respectively. The higher gross return, net return and B:C ratio were obtained with 75% and 100% N and P2O5 levels with soil and seed applied biofertilizers.
