Utilization of Compost and Compost Tea for Improving Egyptian Hybrid Rice One Cultivar

Abstract

Presently, Compost and compost tea with additional chemical fertilizers increase the organic carbon and soluble salts of soil, finally enhance the productivity of Egyptian hybrid rice one (H1). A field experiment was conducted in two successive seasons 2015 and 2016 at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafrelsheikh, Egypt; to evaluate the influence of different chemical fertilizers (NPK) levels with combined compost and compost tea on yield, yield attributes, chemical compositions and quality of grains of Egyptian hybrid rice one. A randomized Complete Block Design with four replications was used. The results indicated that there were significant positive effects of chemical NPK fertilizers with compost and compost tea on number of panicles m-2 at harvest, filled grain percentage, 1000-grain weight, N uptake in grain and straw, phosphorus and potassium content as well as grain quality. Combination of chemical fertilizers with compost and compost tea were gave the maximum crop yield as well as all the previous characters higher than for the single application of organic or chemical fertilizer alone. Thus, it concluded that the applying N110P24K40 + compost as organic fertilizer + compost tea as bio-organic fertilizer could be used successfully to enhance the productivity of Egyptian hybrid rice one, without any significantly differences with N165P36K60 as recommended NPK doses. Integrated use of chemical NPK fertilizer with compost or compost tea positively affected the yield attributes and yield of hybrid rice and contributed in reducing chemical NPK fertilizers by 1/3 as well as minimizing the cost of inputs and environmental pollution.
