Abstract: Reproductive development and growth by crops is especially important for human welfare because we depend on cropfruits and seeds, directly and indirectly, for most of our food. Seed production by crops depends on vegetativedevelopment and growth, development of pollen and egg, pollination, and fertilization. The final size of individualseeds generally hinges on cell division within the embryo, followed by seed filling and maturation process.Environmental conditions prior to the shift to reproductive development usually affect by influencing photosynthesisper unit of leaf area, canopy development and interception of solar radiation per unit of ground area, and initiation ofpotential fruiting site; a strong positive correlation between canopy photosynthesis per unit of ground area and seednumber exists for most crops. For many crops where they are now grown, an increase of just a few °C significantlyreduce yield. Dependence on soybeans for food and feed has increased rapidly in many countries during the last 30years. Nutritionists believe that utilization of soybeans should continue to increase in order to provide betternourishment for people throughout the world. For this goal to be realize, present production areas must produce moresoybeans and new production areas must be established.
