Effect of Neem, Heglig Leaves aqueous extracts and Nitrogen fertilization on Striga and growth Yield of Wheat

Abstract

Pots experiment was conducted, during the summer season 2019, at the College of Agricultural Studies (CAS), Shambat, Sudan University of Science and Technology (SUST), Bahri Locality, Khartoum State. The experiment was carried out to determine the effects of the Neem (Azadirachta indica), Hglig (Balanites aegyptiaca) three different concentrations (2.5%, 5% and 10%) and effect of nitrogen is also three doses (40, 80 and 120kg/fed) on the growth and productivity of wheat cultivar (Imam). The experiment was designed with random sector complete with three replications. The results of the experiment showed that the number of Striga plants increased with the number of weeks after the transplant. After 8-14 week, all the concentration of the two plants above and nitrogen kg/fed increased significantly in plant height. After 14 weeks, concentrations of 5% and 10% Neem, Hglige and nitrogen (80, 120kg/fed) reduced the wet weight of the bud . the concentration of 10% of Neem, Hegilg and nitrogen 120kg/fed reduced the dry weight of gram of Striga parasite. The concentration of 2.5% of Neem, (2.5%, 5%) of Heglig and nitrogen 120kg/fed significantly increased the wet weight of wheat . the above concentration, in addition to nitrogen 40, 120kg/fed significantly increased the dry weight of wheat, the concentration of Neem, Heglig 10% and nitrogen 80,120kg/fed significantly increased the yield of cereals in g/plant and the grin yield kg/fed acre.
