Abstract: Beladanga was chosen for this experiment on the basis of best performance in Saline Belt. This experiment was conducted with the objectives to identify the best source of nitrogen from organic and inorganic fertilizer, and their combinations for increasing growth, flowering fruit yield and quality of chilli. The experiment was designed with nineteen treatments and three replication. The selected manures were Cowdung manure, Neem cake, Poultry manure, Vermicompost, Phosphocompost and Mustard cake, easily available in this area were applied in different combinations with inorganic fertilizer (Urea) at three levels(25%, 50%, and 75%) to enrich growing media. Increasing dose of N (25 to 75%) from mustard cake induced flower early by 2-3 days with combination of urea. Maximum delay in flowering by 4 days were observed, when plants were manured with 50% N from cowdung and Phosphocompost with 50% N from urea. It was observed that all levels of nitrogen received from vermicompost showed very pronounced effect on flower production (250.20-260.20) of chilli. But best combination was obtained with 50% N from both the sources (Vermicompost and Urea) and produced 42.19% more flowers (260.20) as compared to control and lowest (120.60) no. of flowers was obtained with the combination of 25% N from Phosphocompost along with 75% N from Urea. Regarding no. of fruits per plant, the best combination of urea and vermicompost at 50% obtained 51.55% more fruits per plant (161) over control. Weight of individual fruit was highest (7 g) under treatment with 50% nitrogen both from vermicompost and urea and lowest weight was found under control (4.0g) i.e. without application of nitrogen. The plant produced average highest yield (1127.0g/plant) when treated with 50% N from VC + 50% N from Urea, whereas, lowest (312.0g/plant) performance was observed with the plant without nitrogen in control. During the Second year of the experiment, almost same trend was found in above mention parameters. The combination played an important role in vegetative growth and yield i.e. increased number of fruits per plant by 55.55%, increased weight of individual fruit by 42.80% and increased yield per plant by 261.21% more than control (without Nitrogen). The highest B:C ratio of 5.52 was also obtained in this combination, indicating the maximum economic benefit. But, regarding the qualityaspect,Neemcakeasasourceofnitrogen@25%playedavitalroleforimprovementofcapsaicin and ascorbic acid content in the fruit viz. capsaicin content, 114.20mg/g of dry biomass and ascorbic acid content, 185.50 mg/100g of green edible chilli and same trend was found in the second year also.
