Abstract: A filed experiment were conducted on a clay soil during two successive seasons of 2008/2009 and 2009/2010 at Sakha Agric. Res. Station (N 310 00\ , E 300 59\ at an altitude 6m), Agric. Res. Center, Kafr-El-Sheikh Governorate, Egypt,. The experiments were carried out to find the effect of anhydrous ammonia injection with different rates i.e. 0, 25, 50 and 75Kg N/fed., compost i.e. 0, 5, 10 and 15m3/Fed. and biofertilizer inoculation (Bacillus polymyxa) as a N-fixer and their interactions on the production of wheat (Sakha 69), yield components and NPK uptake/plant.
The obtained results could be summarized as follows:
Regardless of compost and biofertilizer treatments, dry matter yield, NPK uptake per plant, number of spike/plant, number of tillers/plant, spike length, yield (grain and straw) and protein content increased with the application of anhydrous ammonia. However, the concentration of carbohydrate was decreased by increasing the rates of anhydrous ammonia.
Regardless of anhydrous ammonia and biofertilizer treatments the application of compost gave the same trend of anhydrous ammonia.
Regardless of anhydrous ammonia and compost the inoculation of Bacillus polymyxa also increased dry matter, NPK- uptake/plant, yield and yield components as well as protein percentage in grains.
Keywords: (Anhydrous ammonia, biofertilizer, organic compost, nitrogen, phosphorus, potassium, wheat.)
