Performance of GNV 1089 rice variety for yield and water productivity under direct seeded rice in Upper Krishna Command Area

Paddy is the major crop growing in upper krishna project command area. The growing of long duration rice varieties consumes more irrigation water than short duration varieties which lead to soil salinization and water scarcity problem among tail end farmers. Hence, ICAR-Krishi Vigyan Kendra, Yadgir conducted two years field trials on assessment of different varieties under different sowing methods during 2018 and 2019 kharif seasons. The design consist five genotypes viz, GNV 1089 (V1), RNR 15048 (V2), BPT 5204 (V3), GGV-05-01 (V4) and SIRI 1253 (V5) as main plot and different sowing methods viz., traditional transplanting rice (TTR) and direct seeded rice (DSR) as sub plot. A spilt plot design was used at different cluster villages at selected farmer’s field. The observations on crop yield and quantity of water applied were recorded. The pooled data of two seasons showed that, highest average grain yield 6184 kg/ha was recorded in GNV 1089 (V1) followed by GGV-05-01 (V4) and lowest average grain yield 5524 kg/ha in V3. The highest water productivity was recorded in GNV 1089 (5.90 kg/ha/ mm) under DSR and least was in BPT 5204 (4.30 kg/ha/mm). The study revealed that, more crop yield and water productivity can be achieved in short duration variety under DSR method. The highest B:C ratio (2.76) was recorded under GNV 1089 (V1) of DSR and lowest B:C ratio (1.30) under SIRI 1253 (V5) of TTR over rest of the treatments. There was a significant difference in B:C ratio of 1.46 under TTR over DSR method. The farmers were satisfied with GNV 1089 crop performance due to its early harvest and less consumption of irrigation water. Growing of GNV 1089 under DSR method in command area will reduces the water scarcity problem and increase the farm income by using less crop inputs.
