Standardization of leaf nutrient status of Khasi mandarin by correlation of leaf nutrient status, fruit yield and quality

The experiment was carried out in 16 different selected orchards of the Aalo belt of Pasighat in Arunachal Pradesh. Soil and leaf analysis for all the selected orchards were done and correspondingly yield and yield attributing characters were recorded. Data were analyzed statistically using randomized block design (RBD) and correlation analysis for soil with leaf nutrient content and leaf nutrient content with fruit yield and quality were carried out. Correlation studies indicated that fruit yield and quality parameters were positively and significantly correlated with leaf N, K, and Ca content. Other elements like Mg, S, Mn, Zn, Cu and Fe had moderately positive effect on the fruit yield and quality parameters on both the years.
