Growth and Yield Production of Canola as Affected by Organic and Mineral Fertilizers Application under Drought Stress Conditions

Field experiment were carried out at the Research and Production Station of National Centre, Nubaria region, Behiera Governorate, Egypt during 2019/2020 to study effects compost zinc foliar application on growth yield production canola under drought condition. The water stress treatments (75 40% holding capacity, WHC) occupied main plots rates (0, 2, 4 6 ton fed-1) allocated random in sub-plots with a rate 0, 50 100 ppm. Data noticed that increase associated increasing SPAD red RWC both irrigation where 75%WHC scored highest values than 40 %WHC. Results indicated was characters plant height, number branch, pods 1000 seeds weight as well as, seed yield, biological affected by their interaction normal treatments. Also, data illustrated tolerance indices (SSI, STI, GMP, YI, YSI, MP, TOL HM) Compost Zinc sulphate. attained after 6.0 fed-1 spray ZnSO4 concluded that, is important for enhancing parameter
