Yield gap analysis ‘Infarmers’ participatory seed production plot of lentil (Lens culinaris Medic.) at old alluvial zone of West Bengal, India

Abstract

A field study was carried out during rabi2016-17, 2017-18 through the demonstrations to analyse the yield gap of lentil in Dakshin Dinajpur district of old alluvial zone, West Bengal, India in real farm situation. Seed inoculation with rhizobium along with foliar spraying of supplemental nutrient NPK (19-19-19) and micronutrient Boron as solubor (20.5%B) at 25-30 DAS and 45-50 DAS in basal application of 20:40:20N: P2O5: K2O kg ha-1showed better seed yield (1092.18 kg ha-1 and 1115.24 kg ha-1 during 2016-17 and 2017-18 respectively) in comparison to the traditional farmers’ practice (783.94 kg ha-1 and 798.16kg ha-1 during 2016-17 and 2017-18 respectively) with decreasing technology gap as well as technology index. On an average of two years, demonstration package also fetched a good return per rupee of investment (2.19) in comparison to farmers’ practice (1.82).
