abstract
ICAR-Krishi Vigyan Kendra, Koppal, has conducted frontline demonstrations on salt tolerant paddy variety GNV-1109 for higher productivity under saline soils in Gangavathi blocks of Koppal District (Karnataka) during kharif 2022-23 and 2023-24 to demonstrate production potential and economic benefits of improved production technologies comprising salt tolerant variety GNV-1109 were compared with check variety (BPT-5204). The demonstrated variety (GNV-1109) observed 31.63 percent higher grain yield as compared to check variety. The extension gap, technology gap and technology index were 17.36 q ha^-1, 2.77 q ha^-1 and 3.69 percent, respectively. Further, demonstrated variety observed higher gross return (Rs. 1,51,599 ha^-1 ), net return (Rs. 83,804 ha^-1) and higher B:C (2.21) as compared to check variety. Therefore, GNV-1109 variety was suitable under saline soil conditions in Koppal district of Karnataka state.
