VARIATION OF GROWTH AND YIELD OF CHILLI WITH DIFFERENT DOSES OF NITROGEN IN LAMJUNG DISTRICT, NEPAL

Abstract

The study was undertaken to assess how the growth and yield of the NS-1701 chili variety were impacted by different nitrogen doses in the Lamjung district’s Rainas area. The study involved arranging five different treatment combinations within a Randomized Complete Block Design (RCBD), with each combination being replicated four times. The application consisted of doses (0 kilograms per hectare, 30 kilograms per hectare, 60 kilograms per hectare, 90 kilograms per hectare, 120 kilograms per hectare). Various parameters related to plant growth and yield were observed throughout the study timeframe. The data underwent statistical analysis utilizing Microsoft Excel and R-studio software. Duncan’s Multiple Range Test (DMRT) was applied to distinguish means at a significance level of 5% for the purpose of separation. Growth characteristics such as plant height and the quantity of branches, along with yield-related attributes like fruit length, number of fruits per plant, individual plant weight, and yield (tons per hectare), displayed noteworthy variations until the point of harvest. Among varying nitrogen quantities, the most pronounced plant height (82.40 cm), branch count (8.38), fruit length (11.41 cm), fruits per plant (116.55), per-plant yield (475.5 gm), and overall yield (31.70 t/ha) were achieved with the application of 120 kilograms of nitrogen per hectare. Across all characteristics studied, the analysis of variance (ANOVA) indicated a noteworthy disparity between the various nitrogen doses concerning both yield and growth parameters. Among the range of nitrogen doses tested, the utilization of 120 kilograms of nitrogen per hectare resulted in enhanced growth and yield characteristics. This outcome could be proposed as a beneficial approach for cultivating chili in both the Lamjung district and comparable agro-ecological circumstances.
