The field experiment was conducted on guava cv. Hisar Safeda planted under different plant density to study the changes in nutrient composition of leaves after pruning and pinching. A significant difference was observed in N, P and K content due to different pruning levels and pinching numbers at different planting density of guava during rainy season. The highest N, P and K content was recorded in leaves taken from plants subjected to severe pruning up to 60% removal of shoot followed by 40 and 20% removal of shoot as compared to leaves taken from unpruned plants irrespective to pinching and spacing. Regarding pinching, the maximum N, P and K content was recorded in leaves taken from plants pinched twice, which was followed by leaves taken from plants pinched one time and the minimum in leaves taken from control plants with no pinching irrespective to pruning and spacing, while irrespective of pruning and pinching spacing also significantly affected the leaves nutrient composition as highest N, P and K content was registered in leaves taken from plants at 5x5 m spacing, which was followed by leaves taken from plants at 5x4 and 5x3 m spacing and the minimum in leaves taken from plants at closer spacing (5x2 m). The interaction between pruning and spacing was significant in respect to nitrogen content of leaves during rainy season, while other interactions were non-significant. However, the interaction effect due to pruning levels, pinching numbers and spacing was non significant in respect to P and K content of leaves during rainy season.
