Field experiment was conducted to assess the effect of nitrogen and farmyard manure (FYM) on leaf content of pear cv. Punjab Beauty. The 15 treatments comprised of nitrogen levels i.e. 0, 200, 400, 600 and 800 g per plant and farmyard manure i.e. 30, 60 and 90 kg/plant. The nitrogen leaf content of pear increased with increasing doses of nitrogen whereas phosphorus and potassium leaf content decreased. The pear leaves nitrogen content was 2.43% with 800 g nitrogen/plant. The nitrogen, phosphorus, and potassium nutrient content of leaves increased with increasing doses of FYM. The maximum leaves nitrogen 2.41%, phosphorus 0.20% and potassium 1.37% nutrient content with application of 90 kg of manure/plant. The interaction between nitrogen and FYM is positive impact on leaves nutrient content. The nitrogen 2.51%, phosphorus 0.19% and potassium 1.35% was recorded with 600 g nitrogen and 90 kg/plant. Further, regression analysis revealed that leaf nitrogen content (R2 = 0.979) influenced the fruit yield and fruit weight significantly. It is concluded from this study that 600 g nitrogen along with 90 kg FYM was optimum doses for Japanese pear for better leaves nutrient status, higher fruit weight, and yield of pear fruit crop.
