Effects of phosphate dissolving bacteria and growth promoters on growth, yield and chemical composition of pigeon pea under different levels of phosphorus fertilization [electronic resource].

Includes reference.

Two field experiments were carried out during the two successive seasons 2004 and 2005 to study the effect of phosphate dissolving bacteria and spraing vitamin Bl, dry yeast and (vit. Bl + Yeast) on growth yield and chemical composition of pigeon pea. under different levels of phosphorus fertilization (0.0, 7.75, 15.50 and 23.25kg P20s/feddan) The results showed significant increases in plant height, number of pranches, number of leaves, stem diameter, number of pods/ plant, pods weight! plant, pods weight/ plot, 100-seed weight, seed weight/ plot and seed content of phosphorus by spraing plants by vitamin B1, yeast and their mixd use and using biofertilizer and phosphorus fertilization rates 15.5 and 23.25 P20s/feddan. Seed contents of dry weight, total nitrogen, potassium, total protein and total carbohydrates showed insignificant response under all treatments in both seasons.
