Production of tropical oyster seed in hatchery

Oysters have been collected from wild since long time ago for human consumption. Recent development in aquaculture has allows the production of its seed in hatchery. Factors favoring the oyster production are stocking density, water quality and the availability of live food. These factors can increase the growth and survival of the oyster. Fundamental knowledge on life cycle and biology of oyst...

Seed Physiology, Production & Technology

Detasseling is used in hybrid corn (Zea mays L.) seed production to ensure harvested seeds have the desired genetic complement. Both mechanical and hand detasseling result in loss of some leaf tissue and plant N. The objective of this study was to determine if seed yield and quality and N content of grain and stover were affected by leaf removal during detasseling. The treatments evaluated were...

Eggplant Seed Production

The varieties of Solanum melongena L. display a wide range of fruit shapes and colors, ranging from oval or egg-shaped to long club-shaped; and from white, yellow, green through degrees of purple pigmentation to almost black. Most of the commercially important varieties have been selected from the long established types of the tropical India and China. In the past, farmers maintained and suppli...

Groundnut Seed Production Manual

Seed is the basic input in agriculture. The quality of seed used by farmers determines the status of agriculture they practice. However, for maximum gain in productivity the use of both improved varieties and improved integrated crop management practices are required. Not only do they contribute to increasing productivity individually, but they also act synergistically. Seed of improved varieti...
