摘要：A field study was conducted during the summer seasons of 2017 and 2018 to investigate the effect of various organic materials and inorganic fertilizers on the behavior of Egyptian hybrid rice (EHR1).The experiment was laid out in split-plot design in four replications,where main plots were assigned to NPK fertilizers and sub-plots were allocated to organic materials.The NPK fertilizer’s treatments were: full dose,2/3,1/3 of NPK recommended doses and control (without any mineral fertilizer application).The organic materials treatments were: Control (without any organic materials application),rice straw compost,farm yard manure,chopped rice straw and chopped rice straw mixed with farm yard manure.Our results demonstrated that,the application of NPK fertilizers along with rice straw compost and farm yard manure significantly enhanced grain yield and its attributes of Egyptian hybrid rice.The application of a full dose of NPK integrated with compost or farm yard manure incorporation enhanced the uptake of nitrogen,phosphorus and potassium.The sufficient application of NPK fertilizers coupled either with farmyard manure or rice straw compost could enhance soil organic matter content after harvest.
