Abstract
1. INTRODUCTION
Peanut (Arachis hypogea L.) i o be one of the most important leguminous crops in the World and in Egypt too because all parts of the peanut plant can be used. The peanut is grown primarily for human consumption and has several uses as whole seeds or is processed to make peanut butter, oil, and other products. The seed contains 25 to 32% protein (average of 25% digestible protein) and 42 to 52% oil. A pound of peanuts is high in food energy and provides approximately the same energy value as 2 pounds of beef, 1.5 pounds of cheddar cheese, or 36 medium- size eggs Woodroof, (1983).
Peanuts are consumed chiefly as roasted seeds or peanut butter in the United States compared to use as oil elsewhere in the world. Americans eat about 4 million pounds (unshelled weight) of peanuts each day. Approximately two- hirds of all U.S. peanuts are used for food products of which most are made into peanut butter. Salted and shelled peanuts, candy, and roasted-in-shell peanuts are the next most common uses for peanuts produced in this country. The remaining one- third of annual production is used for seed, feed, production of oil, or exported as food or oil.
Non food products such as soaps, medicines, cosmetics, and lubricants can be made from peanuts. The vines with leaves are an excellent high protein hay for horses and ruminant livestock. The pods or shells serve as high fiber roughage in livestock feed, fuel (fireplace ”logs”), mulch, and are used in manufacturing particle board or fertilizer.
Peanut production is affected by different factors such as climatic condition, soil fertility, water supply, varieties and plant population per/unit Varieties of peanut differed in growth habit where some of the mare semi- spreading and others are erect. Their root system may vary in volume and size and may be different capabilities to absorb nutrients, and there are many problems facing the production of peanut in newly cultivated sandy soil like unfiling pods, poverty of sandy soil, high loss of elements by leaching and its low field capacity.
Peanut cultivation is thrived in the reclaimed sandy soil. In addition, has the ability for improving the physical structure as well as the fertility such as soil types but in Egypt after built the High Dam we had a problem of plant nutrients and balanced fertilization containing micronutrients became, nowadays, of great importance.
So this present investigation was carried out to study the influence of nitrogen fertilization and foliar application micronutrients on productivity of peanut (Arachis
hypogaea,L.) Under sprinkler irrigation in newly reclaimed soils.
