Impact study on climate resilient technology demonstrated in NICRA village-Choma kot in Vertisol of Rajasthan

Chaumakot in Kota district of Rajasthan is a water scarcity village. The annual rainfall is 780 mm. The soil of the village is clay loam heavy textured with pH 8.20–8.53, low in available nitrogen (145–160 kg/ha), organic carbon (0.48–0.50%), medium in available phosphorus (23–34 kg/ha) and high in available potassium (345–365 kg/ha). Climate-resilient technologies i.e. raised bed planting in soybean and wheat, short duration varieties of soybean (JS 95–60 and JS 93–05), in-situ moisture conservation by field bunding, Broad bed furrow, deep ploughing and inter cropping on soybean + maize (5: 2 rows) were demonstrated at farmer fields along with existing practices during kharif and rabi seasons of 2011–2013 under NICRA. Results revealed that raised bed planting in soybean and wheat gave the highest seed yield (18.25 and 61.92 q/ha) and B: C ratio (3.44 and 4.65), respectively in comparison to conventional sowing. Drought resistant variety JS 95–60 took minimum number of days for attaining maturity and gave higher seed yield(17.60 q/ha) and B;C ratio(3.18) over check variety JS 335. Cultivation of soybean and mustard after adaptation of moisture conservation technologies proved better with 43.42, 16.12 and 12.77% increased in seed yield of bunding-soybean, deep ploughing-soybean and BBF-mustard plots over the respective check. Inter cropping of Soybean + Maize (5: 2 rows) system produced higher profit (Rs 60, 360/ha) and B: C ratio (3.48) over sole soybean and maize and the system was found more efficient, profitable and suitable for rainfed situations. These climateresilient technologies will help the farmers to cope with such extremes situations.
