Importance of Organic Manuring and Mineral Fertilization for Wheat Yield and Its Components in El-Dakahlia Governorate .

Abstract

A factorial field experiment on wheat crop was conducted during two successive growth seasons of (2009/2010) ; (2010/2011) as two different On-farm trials sited in El-Dakahlia Governorate. The factors involved organic manuring from two biological treating composts of rates (0, 10 and 20 m 3 .fed-1) and NPKZn-mineral fertilization of the optimum recommended rates. The two experimental sites were clayey in texture have the average values of salinity index ECe = 3.8 dS.m-1 ; pH = 7.8 and the available soil forms of N , P , K and Zn nutrients were : 30 , 19 , 600 , 0.6 ; respectively. The obtained results indicated the following points : 1-Such soils have to be manured with composts and fertilized with optimum recommended NPKZn-mineral fertilizers for obtaining higher wheat yields. 2-Grain and straw yields have been increased significantly as a result of adding organic manuring (in forms of composts). Higher wheat yields were realized by applying (10 or 20 m 3 .fed-1) treatments. 3-The biological treated compost realized economically higher values of wheat yield relative to the untreated one. 4-The NPKZn-mineral fertilization with optimum recommended rates has increased the values of such wheat parameters. 5-The significant interaction effects of organic composting and NPKZn-mineral cofertilization indicated that : the highest yield and its component were obtained by applying the treatment of (bio-treating compost of 10m 3 .fed.-1). Along with optimum recommended rates of NPKZn mineral fertilizers.

Effect of Mineral, Organic and Bio Fertilization on Wheat Production in Two Different Soils

“…The application of organic residues and biofertilizers are considered as promising practices of improving the nutritive and productive capacities of such soils either directly or indirectly (El-Sirafy et al, 2012).…”

Effect of Organic Manure and Phosphorus Fertilization on Wheat Crop in Salt-Affected Soils.

“…On the other hand, Pfertilization from (calcium super phosphate source) reacts as source of Ca ++ for replacing Na + in such soils (Genaidy, 2011). Also, El-Sirafy et al, (2012) showed that wheat yield components have been increased by applying organic manure, bio-treated compost along with N, P, K and Zn mineral fertilization. So the objective of this presented research is to indicate the main effects of organic fertilization rates (as compost) and phosphorus fertilization (as calcium super phosphate) as well as interaction effects on wheat yield, wheat grains -N, P concentrations and protein content in slightly salt-affected soils.…”
