Abstract: The effect of some alternative fertilizers, namely anhydrousammonia in comparing with urea, humic acid, rock phosphate andfeldspar on growth, yield and its components and nutrient uptake andits availability in soil after harvest for wheat plant (cv Beni Swif 1)were evaluated in a field experiment. The experiment was conducted atSids Agricultural Research Station (ARC) Beni Swif Governorate2010/2011 and 2011/2012 seasons in split plot design. Nitrogensources, i.e. anhydrous ammonia or urea at rate of 75 kg N/fed werelocated in the main plots. While, natural fertilizer treatments (without,humic acid, rock phosphate, and feldspar and their combinations atrates of 10, 300 and 400 kg/fed respectively) were added in the subplots.The results show that anhydrous ammonia significantly producedtallest and heaviest plants, more numbers of both spikes/m2 andgrains/spike as well as higher 1000 grain weight and grain and strawyields when compared with urea. Also, plants incorporated withanhydrous ammonia absorbed more N, P and K than that with urea.Injected the soil with anhydrous ammonia significantly improved soilavailable nitrogen after wheat harvest, while soil available P and Kwere not affected. The treatments effects of natural fertilizerscomparing with, without natural fertilizers on growth parameters (plantheight, dry weight/plant, number of spikes/m2, number of grains/spikeand grain and straw yields) could be arranged in the followingdescending order: humic acid > rock phosphate > feldspar. Combinedhumic acid with rock phosphate and /or feldspar were enhanced itseffects than sole applications. Humic acid, rock phosphate or feldsparyielded highest N, P and K uptake by grain and straw, when comparedwith control. Combined natural fertilizers with each other producedmore nutrient uptake than the single one. Humic acid applicationenhanced soil available N, P and K, however rock phosphate andfeldspar significantly improved soil available P and K, respectivelythan untreated control.
