Effect of integrated nutrient management in rice (Oryza sativa L.) under SRI technique: A review

Author(s):

Abstract:
The system of rice intensification (SRI) is a rice crop management system developed in the 1980s in Madagascar, reportedly enhances yield through synergy among several agronomic management practices with less water requirement. This study was carried out to investigate the effects of rice cultivation methods and nutrient management on growth, physiology and grain yield of rice. The improvement in plant functions resulted into significant gain in grain production. In our earlier efforts, it was also observed improvement in phenotype and physiological functions under SRI compared to conventional method of transplanted rice. Overall, grain yield was increased by 34% with SRI practices due to significant improvement in morphology (Tillering and light interception) and physiology (chlorophyll content and photosynthesis rate) of crop than crops grown with conventional method. This was plausible reason for improvement in yield contributing characteristics and ultimately higher grain yield under SRI than from conventional transplanting method. Lower grain yield was obtained with organic fertilization than INM crop, but it would be of more significance in improving soil health and reduction in environmental hazards. It is also important to note here that organically fertilized SRI crop gave significantly higher yield than both organically and INM crops under conventional transplanted method.
