The study involved growing two tolerant pea (Kashi Samrath and Kashi Samridhi) and two susceptible (Matar Ageta-7 and AP-3) genotypes with increasing added rate of Al (0, 12 ppm and 24 ppm) in soil. Al application in soil resulted in significant decrease in nutrient availability of soil mainly nitrogen, phosphorus and potassium. The addition of Al caused decrease in soil pH causing a negative effect on the yield of susceptible pea genotypes. However, in tolerant genotypes, there was no significant effect on yield, despite a decrease in soil pH and an imbalance of nutrients. Keywords: pH; aluminium interaction; Pisum sativum. 1. INTRODUCTION Garden pea (Pisum sativum var hortense) is grown worldwide for its quality protein in the human diet. Among biotic and abiotic stresses affecting pea yield, aluminium (Al) toxicity is a major problem, particularly in acidic soil condition. Worldwide, soil acidity problem Original Research Article
