Impact of applying different sources of N fertilization on soil availability of macronutrients and wheat yield [electronic resource].

Includes references.

A field experiment was conducted at Ismailia Agric. Exp. Station through the winter season 2004/2005 to study the impact of organic, inorganic, N·fertllization and biofertilizers on NPK availability and wheat grain yield. The experiment was laid out in a split split design with three replications. The treatments were added before sowing as follows: organic fertilization was no compost and 5 ton compostHed. Nitrogen fertilizers were 50%, 75% and 100% of the recommended nitrogen doses. Four inoculation types were used: 1- no inoculation, 2- inoculation by Bacillus polymyxa; 3~ inoculation by Saccharomyces cerevisiae and 4- inoculation by mixture of Bacillus polymyxa and Saccharomyces cerevisiae. Wheat grains (Triticum vulagre) c.v. Giza 168 were sown on 1stt' November 2004. Six months after sowing plants of each plot were cut and grain yield (kg/fed) was achieved.
