Online published on 21 March, 2016. Abstract The studies were undertaken on integrated plant nutrient management on guava (Psidium guajava L.) cv. Allahabad Safeda, during 2011–12 at JNKVV, College of Agriculture, Rewa, Madhya Pradesh. The results showed that plant height had highly significant positive association with canopy height. There was positive but non-significant association with girth of scion, plant spread N-S and volume of trees. Negative association was found with the circumference of rootstock and spread E-W. The number of fruits/tree had highly significant positive association with fruit yield. Negative association was found with average weight/fruit. Fruit yield/tree showed significant association with fruit yield/ha but non-significant association with average weight/fruit. Average weight/fruit was associated non-significantly with fruit yield/ha. The nitrogen content in leaf was positively associated with phosphorus content in leaf, potassium content in leaf, leaf chlorophyll content index and leaf area index. Total phosphorus content in leaf showed significant positive association with total potassium content in leaf. However, it was positive but nonsignificant with leaf chlorophyll content index and leaf area index. The potassium content in leaf was positively associated with leaf area index and leaf chlorophyll content index. Leaf chlorophyll content index was positively but non-significantly associated with leaf area index.
