However, a field experiment was conducted at El-Riad province close to El-Burouls Lake, Kafr El-Shiekh Governorate. The main target of this work is to evaluate the effect of soil amendments viz. gypsum at application rate of 50% of gypsum requirements (GR=10.4 t/fed), sugar lime (equivalent to GR), farmyard manure (FYM) at a rate of 20 m3/fed.), gypsum+FYM, FYM+sugar lime and a control with unconventional (reuse of agriculture drainage water ECiw 4 dS/m) or non-saline (0.82 dS/m) irrigation water on some soil properties and yields of rice and wheat in a sodic soil (pH >8.5 and ESP 43%). The obtained results showed that the application of soil amendments increased the yield of ... 전체 초록 보기
