Abstract:

A long term field study was initiated in 1989 at Agricultural Research Station, Kathalagere, University of Agricultural Sciences, Bangalore in rice – maize cropping system as alternative to existing system with imposing various nutrients combinations of organic and inorganic source of nutrients. The results of 25th year crop rotation cycle indicated that treatment receiving 25 per cent “N” through paddy straw and 75 per cent NPK through inorganic fertilizers during summer (T9) (6.4 t ha-1 and 5.0 t ha-1) has increased yields in rice and maize, while yield reduction was noticed in control (3.2 and 2.1 t ha-1 in rice and maize, respectively) over period. Similarly, organic carbon content was improved by 0.72 per cent in treatment receiving 25 per cent “N” through paddy straw and 75 per cent NPK through inorganic fertilizers during summer (T9) and 0.70 per cent in plots (T10) 50% N + 50% N Glyricidia and 100 per cent NPK inorganic during summer. A reduction of organic carbon was notice in only inorganic source of nutrient. Adoption of integrated nutrient management (INM) practices and inclusion of light irrigated crop like maize after rice in summer season as alternative to existing rice -rice cropping system by application of inorganic nutrient source along with locally available organic nutrients source in limited irrigated condition save 25 per cent of recommended dose of nitrogen through incorporation of locally available organic source specially paddy straw/green manure crops as nutrient source for rice-maize cropping system.
