ABSTRACT

An experiment was carried out at College of Agriculture, Science and Technology, Lafia, Research and Teaching farm in 2019 to ‘investigate the effects of combined treatment of ash+nodumax and Fertiplus 3-2-7 fertilizer on physiological growth and yield of Soybean. Routine analysis was carried out on the field in both cropping seasons using standard analytical procedures. The field was manually cleared and demarcated into plots measuring 2.5m x 2.5 m. Four ridges of 2.5 m long and a spacing of 0.75 m were constructed per plot with a 1m inter plot boundary. Three fertilizer sources; Nodumax+ash (combined), and Fertiplus 3-2-7 that served as treatments, were properly applied based on specifications. There were plots without fertilizer application that served as control. Treatments were replicated two times and laid out in a Randomized Complete Block Design. Soybean seeds of the variety TGX-1935-3f, TGX-1951-3f, and TGX-1904-6f were drilled into the ridges. The crop was grown to maturity within the season and harvested after twelve weeks. Data collected was subjected to the analysis of variance (ANOVA) using gens tat 12.1 edition. Significant difference among means was observed, and Fischer’s least significant difference was used to separate means. Results from this study showed that there was response to treatment application during the period of plant growth.The result showed that the highest records of all parameters were observed in combined treatment of nodumax+ash, which gave the best yield in terms of grain weight, while Fertiplus 3-2-7 treatment gave the best result in terms of vegetative growth.The result was thus concluded in this order: Combined ash+nodumax treatment >;fertiplus 3-2-7 treatment.
