Abstract

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