An experiment was conducted to evaluate the effect of hot water and chemicals on the quality and shelf life of Amrapali variety of mango at Agriculture and Forestry University, Rampur, Chitwan, Nepal. The experiment was laid out in completely randomized design with 6 treatments and 4 replications. Physiologically matured mango fruits (200±20 g) were treated with distilled water for 10 minutes, hot water @ 50°C for 10 minutes, hot water @ 55°C for 10 minutes, carbendazim solution @ 0.1% for 10 minutes and Sodium hypochlorite solution @ 100 ppm for 2 minutes. The untreated fruits were considered as control treatment. The highest total soluble solid (18.15°Brix), the lowest physiological loss in weight (24.20%) and the lowest spoilage loss (42.05%) were observed in fruits treated with hot water at 55°C. Therefore, the post-harvest treatment of mango fruits with hot water at 55°C for 10 minutes was found to be effective for maintaining the quality and shelf life of mango.

Coffee being one of the emerging crops with high potential to export to earn foreign currency, has been given due importance by the Government of Nepal. Among different agricultural goods produced in and exported from Nepal, the competitiveness of coffee has quickly increased in recent years, thus contributing to the improvement of rural livelihoods. This study was based on review of literature and analysis of secondary data/information. Statistical tools such as correlation analysis was also used to analyze data. According to the official records coffee production area has expanded from around 135.7 ha in fiscal year 1994/95 to 3052 ha in 2020/21 and the production has increased from 12.95 Mt. of dry cherry to 315 Mt. of green beans during the same period. Nepal’s coffee subsector is characterized by low productivity, low production and poor quality. Inter alia, it was mainly due to incidence of insect pests, production done by smallholder farmers in a widely scattered area creating problems in quality control and collection leading to higher cost. The good price, high demand and overwhelmingly organic system of production are the encouraging factors but the formidable challenge remains on fighting with white stem borer and providing incentives for small holder farmers throughout the relatively long gestation period of coffee crop. Apart from low production level, organic certification and quarantine requirements pose serious challenges to export. Coffee produced in Nepal is Organic & Fair-trade and is readily accepted as a Specialty Coffee in specific international markets.

The biological effectiveness of twenty-eight native isolates of Trichoderma along with two known species (Trichoderma viride and Trichoderma harzianum) were tested against Rhizoctonia solani using dual culture technique. Of them, seven isolates and the two species of Trichoderma were tested in pot culture under net-house conditions against wirestem disease of cauliflower caused by R. solani. Inhibitory effects on dual culture were statistically very significant for all tested Trichoderma. Thirteen Trichoderma isolates exhibited more than 90% bio-control index and twenty-three isolates had more or at par with T. viride and T. harzianum. In an in-vitro trial, isolate from Dhankuta (Pakhribas) was most effective against R. solani as evident by the highest bio-control index at 6 days after incubation. Similar to this, in an in-vivo experiment, tested isolates of Trichoderma contributed more or less in the plant canopy area, root length and shoot circumference attributes. Trichoderma isolates significantly contributed to root dry matter and biomass while there was a highly significant difference in reduction of disease severity. T. harzianum and the isolate from Dhankuta (Pakhribas) were most effective for the control of wirestem disease

A study was done in 2021 in the Kailari rural minicipality, Gauriganga municipality, Godawari municipality, and Dhangadhi sub-metro politian city of the Kailali district to analyze the economics of wheat production. A total of 200 samples (50 from each village) were selected by using a simple random sampling technique. Most respondents (91 percent) had agriculture as a primary occupation. The area under wheat (Triticum aestivum) cultivation per household was 0.6 hectare with no significant difference between super zone of the Prime Minister Agriculture Modernization Project and non-super zone areas. The average production per household was 1814.5 kg whereas the yield was 3.3 mt/ha. The average cost of production was NRs. 64,526.62 per hectare and the B:C ratio was found to be 1.492. The Cobb-Douglas function showed that fertilizer, pesticide, land preparation, irrigation, and threshing costs were significant contributing factors to wheat production. The return to scale was found to be 0.261. An Index of severity was constructed to study the problems of wheat production in the study area. Weed infestation, lack of fertilizers, and insect pests were found to be three major problems.

Potato is a vital food source for the high hills of Nepal. The crop requires the right amount of nutrient at the appropriate time for optimal growth and production. However, the low availability, high cost, and inappropriate timing of applying nitrogenous fertilizers like urea have made it challenging for farmers to use the correct amount in their fields. Therefore, affordable and renewable sources of plant nutrients should be used to supplement chemical fertilizers. In addition to this, using organic sources can improve soil properties. To determine the effects of nitrogen supplied through different sources, an experiment was conducted in a randomized block design. There were eight treatments, each with a different combination of nitrogen supplied through urea and various organic sources as N1(100% rec N via Urea), N2 (50 % rec N via FYM + 50 % rec N via Urea), N3 (50 % rec N via PM + 50 % rec N via Urea), N4(50 % rec N via GM + 50 % rec N via Urea) , N5 (75 % rec N via FYM + 25 % rec N via Urea), N6 (75 % rec N via PM + 25 % rec N via Urea), N7 (75 % rec N via GM + 25 % rec N via Urea), N8 (Farmer practices (FYM 10 t ha-1)). The yield of potato tubers was significantly higher when recommended nitrogen was applied 50% through organic manure like poultry, FYM, and goat, and 50% through urea than other treatments, including farmer practice of using 10 t ha-1 FYM. However, the yield was statistically at par with nitrogen via sole urea. Additionally, the application of organic manures led to an increase in soil properties such as organic manure content, nitrogen, phosphorous, and potassium content. In conclusion, application of recommended nitrogen as 50% via organic manures like poultry, FYM, and goat, and 50% N via urea can enhance potato yield while also positively affecting soil properties.

Chemically managed plants impose environmental risks to humans and environment. Using biological approaches to control plant diseases is a more effective and environment friendly alternative. The biological approach to plant disease refers to controlling disease by using organisms like fungi, bacteria and viruses. This can be done by introduction or utilization of resident antagonistic living organisms. Biological control can be achieved through different forms of interactions between organisms and the interactions includes hyperparasitism, antibiosis, commensalism, neutralism, and competition. Various biocontrol agents commonly used against plant pathogens are Trichoderma harzianum, Trichoderma hamatum, Trichoderma viride, Trichoderma koningii, Gliocladium virens, Gliocladium roseum, Paecilomyces liiacinus, Coniothyrum minitans, Bacillus subtilis, Bacillus polymyxa, and Pseudomonas fluorescens.

Live fish businesses are likely to become more popular in Nepal due to their reliable source of food. The live fish food survey data was collected from a Google Form questionnaire in the Nepalese language. This study investigates consumers, retailers, and wholesalers in Nepal's live fish market to identify significant concerns that could be addressed in the decision-making of live fish professionals. Nonparametric tests are used for non-normally distributed data, and parametric tests are used for normally distributed data. The study found high mortality and administrative obstacles of 68.60% and 48.60%, respectively. If the wrong choice of aeration method and equipment is made, more fish will survive in the retailer's shop and during transportation time. Fish Models II and III will be an alternative to the current method of transportation, which shows that increasing the tank capacity by one standard deviation increases fish survival by 0.7 and 0.65 standard deviations, respectively. To increase the dissolved gas, the survey suggests that transportation and aeration methods should be improved. This increases the volume of transportation while using the same resources, meeting market demands.

This paper examines the impact of microfinance in agriculture and livestock in Dhading and Chitwan districts of Nepal. Municipalities within the districts were selected purposefully, and 60 respondents from each district were selected by simple random sampling method to comprise 120 respondents. The study showed significantly higher percentage of people participating in microfinance had self-sufficient food production. Probit regression analysis was done to estimate the impact of different predictor variables on farmer’s participation in microfinance. Although the production, income and gross margin of rice and wheat and gross margin of livestock was found statistically higher among the farmers participating in microfinance, the expense for rice and wheat was also found significantly higher among the farmers participating in microfinance. The result of Probit regression analysis showed six variables namely age of household head, caste/ethnicity, education of household head, agricultural credit, livestock unit (LSU), and annual household income were statistically significant for farmer’s participation in microfinance.
