Genetic progress has brought about a dramatic increase in yield potential per se for almost all production areas around the world. The present study examines the relationship of wheat yield with year of release, yield components, harvest index (HI), biomass production, and plant height. We used aggregative data from 1945 to 2010 to calculate genetic gain in(More)
The increasing food demands of a growing human population and the need for an environmentally friendly strategy for sustainable agricultural development require significant attention when addressing the issue of enhancing crop productivity. Here we discuss the role of integrated nutrient management (INM) in resolving these concerns, which has been proposed(More)
Continually increasing food demand from a still–growing human population and the need for environmentally–friendly strategies for sustainable agricultural development require innovation and further enhancement of cropping systems’ factor productivity. The system of rice intensification (SRI) has been proposed as a suitable strategy to improve rice yields(More)
