Contribution of High-Yield Seeds to The Production, Yield and Area of Major Food Crop Production
This study aims to assess the contribution of HYVs to the production and yield of main food crops (rice, wheat, bajra, maize, jowar) in Punjab and Pakistan. The study is based in the last 44 years on secondary results. For this reason, a comparison is made between period I and period II of the growth rates of yield, production and area, from period II to period III and from period I to period IV. The study demonstrates that the effect of HYV seed on main food crops in growth, yield and region is mixed. HYVs make a remarkable contribution to wheat production, production area and yield growth. Various micro grade studies have confirmed the growing yield characteristics of new seed varieties in India. The implementation of HYVs led to expansion, in period II, of rice and maize production and return growth rates. In Jowar's case, despite having reduced its area and production in the second period, its yield was increased due to the adoption of HYV seeds.
