Effect of bio-inoculants on leaf nutrient status of apple cv. Red Delicious

Significant differences were recorded for total leaf nitrogen, phosphorous and potassium in response to the different fertilizers treatments. The effect of fertilizer regimes on leaf nitrogen resulted in significant difference in which treatment F1 recorded maximum leaf nitrogen (2.04 %) followed by F3 (1.99 %) and F4 (1.95 %). The interaction effect of phosphate solublizing inoculants and nitrogen fixing inoculants on leaf nitrogen recorded significant increase. However, there was non-significant differences in leaf phosphate and potassium in response to these two inoculants. Significant results were recorded in response to interaction effect of nitrogen fixing inoculants and fertilizer regimes. Effect of nitrogen fixing inoculants, phosphate solublizing inoculants and fertilizer regimes recorded a significant increase in leaf nitrogen.
