Abstract

Under high saline conditions, a field experiment was carried out to investigate the role of different rates of compost and N fertilization on yield and nutrients uptake of rice (Oryza sativa L. cv. Sakha 101) cultivated in Sahal El-Hossynia Agric. Res. Station Farm in El-Sharkia Governorate, Egypt and irrigated with drainage water from El-Salam canal during summer growing seasons 2014/2015. Compost was added to soil at two rates (5 and 10 ton fed-1) in combination with three rate of N fertilization (35, 50 and 70 Kg N fed-1). The obtained data indicated that increasing N fertilization from 35 to 70 kg N fed-1 increased significantly straw, grain and 1000 grain weight of rice. The high yield values (2.88 ton fed- 1(straw), 2.11 ton fed-1(grain) and 35.50 g (1000 grain weight) can be obtained under a high level of the N fertilization and compost rate (70 kg N fed-1 and 10 ton fed-1, respectively). As well as increasing of N, P, K, Fe, Mn and Zn uptake of straw and rice grain attributed to increasing N fertilization rate especially under high level of compost (10 to fed-1). Nitrogen fertilization rates under two levels of compost didn’t affect on most nutrients content, except N and P which increased when N fertilization increased under high level of compost (10 ton fed-1).
