Abstract: Field studies were conducted to examine the effects of Phosphorus fertilizer (P2O5) and intra row spacing on the growth components and grain yield of lablab (Lablab purpureus) varieties during 2022 rainy season at Sule Lamido University Kafin Hausa (12.1898°N, 9.9242°E) and Binyaminu Usman Polytechnic Hadejia (12.4506°N, 10.0404°E) Research and Teaching Farms.The treatments consisted of three levels of phosphorus fertilizer (0, 20 and 40kg haˉ¹), three intra row spacings (20, 30 and 40cm) using two varieties of lablab (Highworth and Rongai).The treatments were laid out using Randomized Complete Block Design (RCBD) and replicated three times.The resulst showed that application of P2O5 significantly increased plant height, number of leaves per plant, number of pod per plant, and grain yield at both locations.Grain yield was higher at 40kg P2O5ha -1 at Kafin Hausa while at Hadejia 20kg P2O5ha -1 gave satisfactory grain yield.Intra row spacing significantly affected number of leaves, number of pods, 100 grain weight and grain yield at both locations and 40cm intra row spacing prove to be superior to other spacings.The result also indicated that Highworth out yielded Rongai and recorded superior number of leaves, leaf area, number of pods, 100 grain weight and grain yield at both locations.Therefore, farmers in the study area could be advice to adopt Highworth variety, application of 40kgP2O5kghaˉ¹ and use of 40cm intra row spacing in the production of lablab.
