Completely Randomized Design (CRD) with three replications was used. Initial juvenile population was 30.0±2.8 per 20g soil. The juvenile nematode population was counted 63 days after transplanting and biomass of plants was incorporated in soil. Population was again counted 11 days and 13 day after biomass incorporation. At final count of Juvenile nematode population, it was found highest in tomato (66.6 /20g soil). Highest control was achieved in marigold (2.3 juvenile/20g soil) followed by crotalaria (3.0 juvenile/20g soil. Marigold and crotalaria followed by oat in rotation with tomato were observed as best antagonist plants to control Southern root knot ...

The number of productive trees per unit area was found higher in Nirmalpokhari (55 trees), similarly the cost of production and return were also higher in Nirmalpokhari which were Rs.4427.48 and Rs14685.96 per ropani, respectively. Pre-harvest contract was the most common mode because of low risk associated .The marketing margin per Kg was found higher in Kristinachnechaur VDC (Rs.11.43) whereas the producers' share was found higher in Nirmalpokhari (54.42) indicating better marketing efficiency. Cobb-Douglas production function was used for the analysis of factor of production. Number of productive plants, labor, and manures were found to be significant factors affecting production in Kristinachnechaur while in Nirmalpokhari number of productive plants was found to be highly significant factors affecting production. The output elasticity of production was found to be less than one i.e. 0.952 for Kristi 0.725 for Nirmalpokhari , indicating decreasing returns to scale thus indicating enough space for the expansion of production with the proper utilization of productive resources.

Primary and secondary data were used for this study. All together 10 respondent farmers were selected for production related data, five retailers from Jumla and Nepaljung, one wholesaler from Nepaljung and 10 consumers for market study. Highest wholesale price was observed in May/June-June/July (NRs. 145/kg) while lowest was in Sept./Oct.-Oct./Nov. (NRs. 83/ kg). Similarly highest retail price (NRs. 185/kg) was in the month of June/July and lowest (NRs. 115/Kg) was in Sept./Oct-Oct./Nov. The average farm gate price of apple is too low (NRs.26.93/kg) as compared to wholesale, retail and consumers prices. The producers, traders, transporters, wholesalers and retailers were the main marketing actors of apple. Contractual system before and during production were observed in marketing. Price spread of Jumla apple was assessed with the different actors (contractors, traders, wholesalers, retailers and consumers) in value chain. Apple is the major commodity for income generation so better knowledge on production marketing and value addition through processing should be imparted to the farmers.

Twenty five farmers were surveyed to getthe necessary information. Per ropani cost of cultivation in the first year was Rs114,507. Cost of cultivation from the second year onwards was Rs 40,827. The gross average income was Rs1, 08,275. Thus the benefit-cost ratio in first year was negative and it was 1.65 from the second year onward. Most of the farmers sold tomato to middlemen. FM radio and daily magazines were the major source for daily price information. Market price of tomato was higher between August and October. The lack of quality seed was the major production problem and blight followed by nematode was the major disease and the pest affecting the production.
