Studies on correlation among vegetative parameters, yield parameters, fruit quality parameters, soil and leaf nutrient status of mango (Mangifera indica L.) cv. Alphonso

Abstract

Correlation studies were carried out in Alphonso mango with different physical and chemical parameters during 2017-19 at College of Horticulture, Bangalore. The data on correlation coefficient of yield and its component characters reveals that yield per tree was significantly and positively correlated with number of fruits per panicle (0.94*), soil nutrients and leaf nutrients, while negative significant correlation with days to maturity (-0.72*). TSS showed negative significant correlation with acidity (-0.96**) and spongy tissue (-0.96**) while positive significant correlation with total sugars (0.93**), reducing sugars (0.88**), shelf life (0.96**) and leaf nutrients. Acidity showed negative significant correlation with total sugars (- 0.97**), reducing sugars (-0.79**), non-reducing sugars (-0.53), shelf life (-0.97**) and leaf nutrients, while positive significant correlation with spongy tissue (0.98*). Reducing sugars showed significant positive correlation with shelf life (0.84**) and non-significant positive relation with non-reducing sugars (0.08) and leaf nutrients.
