EFFECTS OF DIFFERENT TYPES OF FERTILIZERS ON GROWTH AND YIELD OF SOYBEAN (Glycine max. L Merril)

Abstract

A field experiment was conducted at the Demonstration Farm, College of Agricultural Studies, Sudan University of Science and Technology, Shambat during the season 2012/13, to investigate the effect of different types of fertilizers on 5 growth and yield of soybean (Clycine max L Merril). The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. The soybean genotype used was (1905 E). The fertilizers treatments consisted of four types of fertilizers: Urea 46% N (180 kg/ha), Compost (2.5 ton/ha), Chicken manure (2.5 ton/ha), Jatropha seeds cake (2.5 ton/ha), untreated Control was used as comparison between plant treatments. Parameters studied included: plant growth (plant height, number of leaves per plant, stem diameters and number of branches). yield components (plant weight, number of pods per plant, pods weight per plant(g), number of seeds per pod, number of seeds per plant, seeds weight per plant(g), 100 seeds weight(g), seeds production (kg/ha) and harvest index%). The results showed that chicken manure fertilizer had significant effect on stem diameter, number of branches, Plant height at 45, 60, 75 days after sowing and on number of leaves at 60, 75 days after sowing. The results showed that Jatropha seeds cake fertilizer had significant different on plant weight as compared to the control. Chicken manure fertilizer had significant different on number of pods per plant and seeds weight per plant as compared to the control. The results showed that nitrogen fertilizer had a significant difference on number of seeds per pod as compared to the control. There were no significant difference among fertilizers treatments on pods weight per plant, number of seeds per plant, 100 seeds weight, seeds production and harvest index%.
