As Indian agriculture is highly dependent on specific climate conditions, the research on the impacts of climate change on Agriculture in general and rice production in specific is a high priority in India. There is an urgent need to focus on climate resilient input management Practices for improving use efficiency and sustaining the rice and rice based cropping system across the country. The issues of Changing climate a combination of water and nutrient management practices were tested aimed at water and nitrogen saving. In order to Climate Resilient Management Practices in rice and rice based cropping systems towards enhancement of grain yield, two field experiments were conducted during Kharif 2013 and Rabi 2013-14 at Perunthalaivar Kamaraj Krishi Vigyen Kendra (PKKVK), Puducherry State experimental farm in a randomized block design with three replication. The treatments were consisted T1: split application of Nitrogen ( 50% basal+ 25% active tillering + 25% at flowering) in puddle soil; T2: Use of bio-fertilizer (Azotobactor and Azolla, to meet 50% of N requirement); T3: Crop residue retention (at least 30%) in cropping system to maintain organic carbon); T4: Non-puddled rice establishment to reduce water requirement; T5: Combination of T1+T2; T6: Combination of T1+T2+T3; T7: Combination of T2+T3+T4; and T8: Conventional method of rice cropping that were tested. The findings of two seasons, use of split application of Nitrogen ( 50% basal+ 25% active tillering + 25% at flowering) in puddle soil and use of bio-fertilizer (Azotobactor and Azolla, to meet 50% of N requirement) with addition of Crop residue retention (at least 30%) in cropping system to maintain organic carbon (T6) was performed excellent by registering higher yield attributes and grain yield of 6050 and 6820 kg ha-1 during Kharif 2013 and Rabi 2013-14 respectively. It’s may be due to use of split application of inorganic fertilizers, biofertilizers and crop residue.
