Field experiment was conducted at Agricultural College and Research Institute, Killikulam during Pishanam season (November- March) of 2015 – 2016. Higher number of tillers/m2, leaf area index (LAI), crop growth rate (CGR) and yield attributes like grains/panicle was realised with application of 75% N as inorganic fertilizer and 25% N as poultry manure attaining biological yield of 15250 kg/ha comparable with 25% N as vermicompost (14760 kg/ha) and was followed 25% N as green leaf manure (14290 kg/ha) and 25% farm yard manure (14090 kg/ha). 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 accomplished 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.
