| Abstract | ||
| Afield experiments were performed during 2020 and 2021rice grown seasons. The site of experiment was located at the northern part of delta, at Ehamoul district, Kafr Eshiekh province under salt affected soil irrigated by saline drainage water. The goal of study is addressing the impact of varying land levelling treatment wet levelling (L1), traditional levelling (L2) and lazer levelling in the terms of lazar levelling (L3) and different urea treatments urea, (N1) sulphur coated urea (N2) and urea+ rice compost straw (N3) on soil salinity, soil physical properties, rice growth, rice yield attributes rice grain yield, water productivity and NPK% in rice grain. The main findings were displayed as following. The apply various land levelling significantly varied in their influence in all studied parameters related to soil and plant. Lazar levelling at dead level (L3) develop the best results since it significantly, reduced salinity level, ESP with improving soil physical properties, especially aggregation concept which reflection higher rice growth, yield attributes and yield as well as water productivity and NPK% in rice grain. Various urea form application markedly different in its impact on studied soil and plant parameter during current trail in both seasons. The urea plus rice compost straw was the best urea form improving soil quality and fertility which giving the higher values of studied growth parameters, yield attribute, and rice grain yield as well as NPK% in rice grain. The urea along with rice compost straw treatment significantly improved aggregation characteristic in both seasons but they did not have significant effect on the rest of characteristics in both seasons. The interaction showed insignificant effect with same trait. It could be concluded that lazar levelling with urea plus rice straw compost is recommended under salt affect soil to ensure high rice grain yield. | ||
