Yield gap analysis of Rabi sorghum through frontline demonstrations in Haveri region of Northern Karnataka

The study was carried out during rabi season of 2016-17 to 2018-19. All the front line demonstrations were carried out in an area of 12 hectares with 30 demonstrations. The results of FLD’s showed that improved technologies consisting of use of improved variety, seed treatment with Azospirillium, balanced fertilizer application and integrated pest management recorded higher yield as compared to farmer’s local practice. The results indicated that on an average 20.52 per cent higher grain yield was recorded in demonstration plots than the local check. The extension gap, technology gap and technology index were 2.45 q/ha, 4.41 q/ha and 3.71 per cent, respectively. Average of three years data revealed that SPV-2217 variety under improved practices recorded higher grain yield of 20.64, 15.19 and 25.29 kg/ha during 2016-17, 2017-18 and 2018-19 and the recommended practice gave higher net returns of Rs 50,788, 15,468 and 51, 000 ha-1 and B:C ratio of 4.14, 2.44 and 4.06, respectively as compared to farmers practice.
