Abstract
Two field experiments were carried out during the two successive seasons of 2000 and 2001 to study the effect of three rates of Nile compost (0.1 and 2 ton/fed.) with three rates of GA substance (0. 25 and 50 ppm) on growth, yield of cowpea and its some physical and chemical properties. The important obtained data are following:
1- Applying organic manure (Nile compost) at high rates (2 ton /fed.) resulted the highest values of growth characters, yield and its components and the contents of nutritional elements compared with the control treatment.
2· Addition of the external hormones G~ at 50 ppm obtained the best vegetative growth characters. the heaviest dry seeds yield (2.140 and 2.342 ton/fed. in the 1 it_and 2 nd seasons), the highest values of total carbohydrate, total protein, the concentration of N, P, K, Fe. Mn, Zn and Cu.
3- The best growth characters, heaviest pods. dry seeds yield, average weight of 100 dry seeds as well as the outnumber of pods/plant the longest pod, the highest values of total carbohydrate, total protein, the concentration of N. P, K. Fe, Mn, Zn and Cu all of them were resulted from that plants received organic compost at the highest rate (2 ton Ifed.) and addition of GA substance at concentration of 50 ppm.
