Comparative yield gaps, economic analysis and constraints in frontline demonstrations of black Soybean ( Glycine max L. Merril) under Rainfed Conditions in Uttarakhand hills

Abstract

Soybean is an important kharif crop which play a vital role in nutritional and livelihood security in Uttarakhand hills. Considering the scope of improvement in productivity through the improved varieties and recommended production technologies, front line demonstrations were conducted by by Krishi Vigyan Kendra, Matela, Almora to know the yield gaps between improved package and practices under front line demonstration (FLD) and farmer’s practice (FP) of soybean crop under rainfed conditions. Front line demonstrations (FLDs) were conducted on farmers’ fields to demonstrate the impact of improved agro-techniques on production and economic benefits under rainfed conditions of Uttarakhand in Almora district during kharif season of two consecutive years i.e. 2016 and 2017. The technologies demonstrated in FLDs recorded additional yield over farmer’s practice. Under FLDs the grain yield of Soybean was increased by 42.72 per cent over FP. The extension gap, technology gap and technology index were calculated as 3.38 q/ha, 18.87 q/ha and 62.9 % respectively. Adoption of improved package of practices in Soybean cultivation recorded higher B: C ratio (1.96) as compared to FP (1.60). Yield enhancement and higher net returns wa sobserved under FLDs of improved technologies in soybean. Thus, the productivity of Soybean could be increased with the adoption of recommended improved package of practices. The study was very convincing to the farming community for higher productivity and returns
