Enhancing productivity through climate smart agriculture under changing weather of rainfed farming system
Abstract: In addressing climate change impacts on agriculture,numerous factors influence a particular location specific adoption of Climate Smart Agricultural technologies. A field experiment was conducted at S.G. College of Agriculture and Research Station, Jagdalpur during kharif 2015 to 2017 and the soil was sandy loam, low in organic carbon (0.43%), available N (178 kg/ha), available P (21.4 kg/ha) and medium in available K (179 kg/ha) showing acidic (pH 6.8) reaction. Experiment was conducted in randomized block design having seventeen treatments in four sets with three replications. Foliar spray @ 2% of nitrogen at the time of flower initiation enhanced the grain yield of rice up to2098 kg/ha in test variety MTU 1010, whereas test variety was MTU 1001produced 1870 kg/ha. Harvested rainwater used for life saving irrigation (2 cm depth) at tillering stage had higher grain yield (1503 kg/ha), net returns (Rs. 41463/ha), B:C ratio (3.16) and WUE (1.10 kg/ha-mm). On other hands, spray of soluble fertilizer (19:19:19 NPK) along with 0.5% ZnSO4 on foliage recorded significantly more grain (2160 kg/ha) and straw yield(2480 kg/ha). Increasing rate of grain yield (6757 kg/ha), net returns (Rs. 57459/ha), B:C ratio (2.74) and RWUE (3.72 ka/ ha-mm) was also found under transplanting of 20 days old seedlings. Scooping created digging out soil with spade in between inter rows of maize recorded more grain yield by 44.5% (1731 kg/ha) than that farmers’ practice (930 kg/ha). Sowing Rice+Dhaincha (1:2) was another important contingent plan because crop sown with Dhaincha together using seed drill supported rice plant initially for growth and development.
