A field experiment was conducted at the research field of Irrigation and Water management Division, Bangladesh Agricultural Research Institute, Gazipur during November 2012 to April 2013 to determine the effect of integrated nutrient management (INM) in onion cv. BARI onion-1 for achieving satisfactory quality seed yield. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications having eight treatments: RDF(115-55-75-20-1.5-1kgNPKSZnB/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. There were significant impacts of INM on the seed yield and yield contributing characters and quality parameters of onion i.e., seed yield, plant height, number of umbels per plant, number of florets per umbel, effective florets per umbel, 1000 seed weight, seed germination, root length, shoot length, seedling vigor index. The highest seed yield of onion (1.28t/ha) and quality seed was obtained with application PL based TC@3t/ha+CF(IPNS). The maximum benefit cost ratio (6.23) was obtained PL @3t/ha+CF(IPNS).

To identify the ideal integrated nutrient management package.
To study the effect of integrated nutrient management (INM) in onion (Allium cepa L.) cv. BARI onion-1 an experiment was conducted at the research field of Irrigation and Water management Division, Bangladesh Agricultural Research Institute, Gazipur during November 2012 to April 2013.The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications having eight treatments: RDF(115-55-75-20-1.5-1kgNPKSZnB/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, ZnO for Zn and Boric acid for B were applied during final land preparation. Urea for N was applied in 3 equal splits at 30, 45 and 60 days after planting (DAP) and the rest half of MoP was applied at 45 DAP. The unit plot size was 3 m x 2 m. The Bulbs were planted on 20 November, 2012 with a spacing of 30 cm x 15 cm. Necessary intercultural operations were done throughout the cropping season for proper growth and development of the plant. The recorded data on different parameters were statistically analyzed by using MSTAT software to find out the significance of variation resulting from the experimental treatments. The difference between the treatment means were judged by Duncan’s Multiple Range Test (DMRT) according to Gomez and Gomez (1984).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 seed of onion @800tk/kg(According to the market price of the year 2013).

It is concluded that application of organic manure with integration of chemical fertilizer significantly influenced the yield and quality parameters of onion seed. However, plants with PL based TC@3t/ha+CF(IPNS) performed better in terms of yield and yield attributes and gross margin than that of other treatments. The maximum benefit cost ratio (6.23) was obtained PL@3t/ha+CF(IPNS) Therefore, a nutrient management strategy that involves organic manure is crucial for nutrient exhaustive crops like onion seed production commercially.
