Abstract
Ameliorating cultivation for maximizing plant prodction, particularly in desert soils, is considered to be of a prime importance, especially in developing countries, like Egypt, suffered from the shortage of cereals which represents the main food. The main target of present study is to evaluate the effect of garbage manure on the growth and yield of wheat plants cultivated in two different desert soils. Trials to improve its fertilizing properties by the application of sheep manure and/or biofertilization with associative N2-fixers and P-dissolver were carried out. Organic carbon, total nitrogen, microbial densities and activity in wheat rhizospheric soil were also determined periodically. These were carried out in the presence of different doses of inorganic N-fertilizer.
