A field experiment was conducted at the research field of Regional Spices Research Centre, Bangladesh Agricultural Research Institute, Gazipur during November 2012 to April 2013 to determine the effect of integrated nutrient management (INM) in chilli cv. BARI Chilli-1 for achieving satisfactory yield of this crop. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications having eight treatments: RDF(120-60-100-30-1.5-1.5kgNPKSZnB/ha); CD@5t/ha+CF(IPNS); PL@3t/ha+CF(IPNS); CD based VC@5t/ha+CF(IPNS); PL based VC@3t/ha+CF(IPNS); CD based TC@5t/ha+CF(IPNS); PL based TC@3t/ha+CF(IPNS) and Absolute contro. Application of different combinations of fertilizer affected plant height, days to anthesis, days to 50% flowering, number of branches per plant, number of fruits per plant, fruit size, fruit yield per plant, single fruit weight, dry fruit yield, number of seed per fruit, 1000 seed weight, seed yield and seed germination influenced statistically but days to fruit setting did not influenced statistically. The highest yield of dry chilli (1.90t/ha) and the highest benefit cost ratio (2.19) was obtained with application of PL based TC@3t/ha+CF (IPNS).

To evaluate the integrated nutrient management on performance of chilli.
The experiment to study the effect of integrated nutrient management (INM) in chilli cv. BARI Chilli-1 was conducted at the research field of Regional Spices Research Centre, Bangladesh Agricultural Research Institute, Gazipur during December 2012 to May 2013.The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications having eight treatments: RDF(120-60-100-30-1.5-1.5kgNPKSZnB/ha); CD@5t/ha+CF(IPNS); PL@3t/ha+CF(IPNS); CD based VC@5t/ha+CF(IPNS); PL based VC@3t/ha+CF(IPNS); CD based TC@5t/ha+CF(IPNS); PL based TC@3t/ha+CF(IPNS) and Absolute control .The total amount of cowdung (CD), poultry liter (PL), vermicompost (VC), trichocompost (TC), TSP for P, ½ of MoP for K, gypsum for S, ZnSO4for Zn and Boric acid for B were applied during final land preparation. Urea for N was applied in 3 equal splits at 40, 55 and 70 days after planting (DAP) and the rest half of MoP was applied at 40 DAP. The unit plot size was 3 m x 2 m. The seedlings were planted on 16 January, 2013 with a spacing of 50 cm x 50 cm. Necessary intercultural operations were done throughout the cropping season for proper growth and development of the plant. Economic evaluation of different treatments was done considering the following rate of costs of the materials: Urea@20tk/kg, TSP@22tk/kg, MOP@15tk/kg, Gypsum@12tk/kg, ZnSO4@260tk/kg, Boric acid@140tk/kg, cowdung@2.5tk/kg, Poultry liter@ 3tk/kg, CD based VC@12tk/kg, PL based VC @12tk/kg, CD based TC 10tk/kg, PL based TC 10tk/kg and dry chilli @200tk/kg(According to the market price of the year 2013).

It is concluded that application of organic manure with integration of chemical fertilizer have significantly influenced the yield and quality parameters of chilli. However, plants with PL based TC@3t/ha+CF(IPNS) performed better in terms of yield and yield attributes and benefit cost ratio than that of other treatments. Therefore, a fertilization strategy that involves organic manure is crucial for nutrient exhaustive crops like chilli for commercial cultivation.
