Impact of Aluminium on Nutrient Profile of Soil under Various Genotypes of Garden Pea

The aim of this study was to examine the influence of Al on nutrient profile of soil grown with various pea genotypes. 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.
