Sweet pepper production using different nitrogen sources in subtropical climate

Abstract

Field experiment was carried out at  Dovan, Palpa of Nepal during May-June, 2010 to evaluate the efficacy of different nitrogen sources on growth and yield of sweet pepper cv. California Wonder. The experiment was laid out in Randomized Complete Block Design (RCBD) using seven treatments and four replications. Treatments were sole application of farm yard manure (FYM), goat manure, vermicompost, and their combination with urea, and only inorganic fertilizers. All treatments were based on fulfillment of required nitrogen to the crop. The results showed that application of FYM-50% + urea-50% increased vegetative growth, resulted into the highest fruit set (45.85%). Fruit weight was the highest (96.54 g) with the same treatment followed by vermicompost-100% (91.14 g). The highest fruit yield (13.524 t/ha) was obtained from FYM-50% + urea-50%.
