EFFECTS OF VARIETIES AND PHOSPHORUS RATES ON THE GROWTH AND YIELD OF SOYBEAN (Glycine max (L) Merrill) IN GOMBE SUDAN SAVANNA

Abstract

Field experiment was conducted during the 2023 rainy season at Teaching and Research Farm of the Faculty of Agriculture, Federal University of Kashere (Latitude 90 54’ 46’’N, Longitude 110 0’ 27’’E at 431 m above the sea level) Akko Local Government Area, Gombe State and at the Teaching and Research Farm of Federal College of Horticulture Dadinkowa, Yamaltu-Deba Local Government Area, Gombe State, Latitude 100 18’E and Longitude 11030 N and altitude of 218m above sea level. The treatments consisted of two varieties of soybean (TGX-1951 and TGX1448-2E) and four phosphorus rates (0, 20, 40 and 60 kg/ha), these were laid out in a Randomized Complete Block Design (RCBD) with four replications. Results of the study showed that soybean variety TGX1448-2E and 60 kg/ha of phosphorus rate significantly gave higher pod yield over TGX-1951 and the other phosphorus rates. The control treatment of no phosphorus applied significantly gave lower pod yield in this study. TGX1448-2E and phosphorus rate of 60 kg/ha should be used by farmers who grow soybean based from their performances in terms of pod yield from the study areas.
