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 climate-resilient technologies will help the farmers to cope with such extremes situations.
