Abstract
The new virgin area in the extreme part of southern Nile Valley of Egypt (Toshky) is very important to produce a clean agriculture tree from pollution. In the southern valley, lands were not used for regular agriculture but they were left for natural cultivation whenever soil moisture was available. The climatic condition is dry and very hot in summer but cold in winter nights. The evaporation rate is very high in summer time; therefore, a suitable technique of water management is required to increase the efficiency of Irrigation water used for crop production. Agriculture is the most important sector for creating and establishing a new settlement. The aim of this work is to study a suitable land and water resource management for crop production under local climatic condition. The study is conducted during summer 2001 and 2002 in the farm of South Valley Agricultural Research Station - Toshky. Agricultural Research Centre. The design of the experimental field involves water application treatments (11: WR+20%, 12: WRi-10%, b: WR only, 14: WR —10% and 15: WR — 20%. The water requirement (WR= 3674m3/fd) is calculated from meteorological data in situ using Penman Monteith method. Salt content of Lake Nasser is 140 ppm. The water management is controlled daily by sprinkler irrigation system during different growing stages. Soil profile is shallow (70 cm down to bedrock). The texture varies from.sandy to loamy sand or sandy loam. Also, many fragments differing in shape, size and colour of various rocks and gravels are dominating on the soil surface and through the whole profiles. Total calcium carbonate varies from 10% to 16%. The soil is very low in organic matter. Soil salinity is low. The soil pH is about 9.0. As a result of soil physical and chemical properties as well as morphological features, the soil taxonomy could be classified as Typic xerofluvants, sand loam mixed. Hyper thermic. Concerning soybean plant, data of the statistical analysis indicate that the plants height, pods numbers. weight of plants and seeds weight are highly significantly related to irrigation water amount treatments. The highest yield was obtained with the highest amount of irrigation water.
