Abstract: Field experiment was conducted at Agricultural College and Research Institute, Killikulam during Pishanam season (November- March) of 2015 – 2016. Higher Plant height, dry matter production, yield attributes and grain yield was realised with application of 75% N as inorganic fertilizer and 25% N as poultry manure (7160 kg/ha) comparable with 25% N as vermicompost (6920 kg/ha) and was followed 25% N as green leaf manure (6710 kg/ha). Higher physiological efficiency was attained when substituting 25% N as poultry manure and was followed by the same proportion of vermicompost. The highest net return with B: C ratio of 3.12 was attained by 25% N substitution as poultry manure while green leaf manure fetched highest B: C ratio of 3.26. From the above results, it could be indoctrinated that application of 75% of recommended N as inorganic fertilizer and substitution of 25% N either as poultry manure or green leaf manure is the desirable integrated nutrient management practice for achieving higher productivity and profitability under transplanted condition.
