In order to assess how leaf nutrient content affected the fruit yield and quality indicators of the pear cultivar "Patharnakh" in the central zone of Punjab, a study was carried out. The results of the study revealed that 13, 10, 30, and 30% of orchards had insufficient leaf N, P, K, and Cu, respectively. However, higher range of N (56%) and P (60%) was noted in leaf sample collected from the selected orchards. Leaf N and K has shown statistically significant and positive relation with tree spread, fruit size and fruit yield whereas, leaf Ca, Cu, Mn and Fe showed negative correlations with fruit yield in the surveyed orchards but results were statistically non-significant. Likewise, Leaf Ca found positive and significant correlation with tree girth and fruit firmness. The present study had shown positive relationships between fruit quality attributes and leaf mineral concentrations to highlight the importance of fertilizer management which will be help in production good quality pear fruits. Additionally, studies help in fertiliser application dosage estimation.

Fruit quality, Leaf nutrients, Pear , cultivar, correlation

One of the main elements affecting the production and quality of agricultural plants is plant nutrition. The growth and development of plants are determined by all necessary ingredients (Rathore, 1991). There is a correlation between a nutrient's content in the soil and in plants and the fruit production as well as its qualitative characteristics. This may be used as a guide to have the best quality and fruit yield possible. According to Awasthi et al. (1998), there is a correlation between apple yield and quality. The production and quality indices of the pear fruit under study are therefore affected by the nutrients in the soil.
