Agro-economic research strategies to bridge yield gap of major crops in Bundelkhand region of India - Agricultural Situation in India - 79(2), May, 2022: p.34-49
The study analyses the yield gap in major crops of viz.; rice, wheat, gram and soybean of Bundelkhand Region of India. The study reveals that the yield gap III between potential yield and average farm yield was found more in cultivation of rice (11.73 q/acre), followed by wheat (6.7 q/acre), soybean (3.89 q/acre) and gram (3.49 q/acre). The yield gap II was found to be more than yield gap I in cultivation of rice, wheat, gram and soybean which denotes that the recommended technologies for cultivation of these crops have reached the farmers field but farmers could not adopt these technologies due to several socio-economic constraints. It is also observed that factors like use of high yielding varieties (HYVs) seed, improved method of sowing (rice), source of seed (rice and wheat), seed rate (soybean and gram), use of DAP (soybean and wheat), application of urea (wheat), treatment with fungicide and bio-fertilizers in rice and gram (Rhizobium, azotobacter and Phosphate Solubilizing Bacteria), irrigation (wheat, soybean and gram)and soil testing (rice and wheat) were found to be positive and significant, while area under irrigation (rice), size of land holding (soybean and wheat) and seed rate (wheat) were found to be negative and significant. This indicates that with the increase in the factors which are positive and significant, the yield of crop will increase and vice-versa. – Reproduced
