Abstract:
The Field demonstrations were conducted to study the performance of salt tolerant paddy varieties in sodic soil in Kaushambi district during Kharif season, 2019-20 and 2020-21 in NICRA village -Umarchha and other adjoining having venerability sodicity. Total Salt affected area under Rice-Wheat Cultivation -18500 ha in the district and a sodic field having pH range 8.9 to 9.2, EC 1.9 dS/m, ESP 39. The traditional/farmer paddy varieties NDR-350 and Pant-12 could not withstand owing to higher salt accumulation in root zone. KVK Kaushambi conducted a farmer field demonstration in 37.5 ha area at 99 farmer fields on salt tolerant paddy varieties viz., CSR 36 and Short duration CSR-43 in NICRA village Umarchha during Kharif season -2016-17 and 2017-18. Gypsum was used for reclamation purpose and Dhaincha as a green manure crop was raised in the selected field and incorporated in soil @ 50% flowering stage at before planting. Uniform cultural practices were applied to all the varieties up to maturity. Proper plant protection measures were taken according to the incidence of pest and diseases. Better growth and yield was observed in CSR-36 paddy varieties, maximum yield was recorded from Paddy varieties CSR-36 (48.5 q/ha.), which was followed by NDR -359 (39.2 q/ha) and CSR-43 (38.8 q/ha.), as compared to traditional/farmer varieties Pant -12 (34.40 q/ha.) respectively. Net return was recorded maximum of (Rs. 42999/-) CSR-36 followed by Paddy varieties NDR-359 (Rs. 29288/-), CSR-43 (Rs.28904/-) and least in Pant-12 (Rs. 22673/-). It was concluded In all, CSR-36 salt tolerant paddy varieties was superior in respect of yield and economically viable. CSR-43 short duration variety performed better than Pant-12 and equal to NDR-359 in terms of yield but CSR-43 beneficial due to short duration characteristics. Out of total potential area for upscaling in the NICRA village as well as adjoining villages ----% of the potential area for in village has been covered through this demonstration and -----% of the potential area was covered through convergence with line departments.
