An experiment was conducted on seven year old tree of guava cv. Apple Colour at Mandsaur, (M.P.) to study the effect of nutrients spray on morphological, yield and quality attributes of guava. The plant height increased (0.42 m, 0.39 m and 0.41m), with urea @ 2%, zinc sulphate @ 0.8% and their interaction (urea @ 2% x zinc sulphate@ 0.8%), respectively. The spray of urea @ 2% resulted in canopy spread E-W and N-S direction (0.89 m and 0.86 m), reducing sugar (5.90 %),non reducing sugar (4.15%), the maximum no. of fruit/ tree (238.57), fruit weight (178.50 g), yield per tree (42.19 kg), while spray of zinc sulphate @ 0.8 % resulted in canopy spread E-W and N-S direction (0.86 m and 0.86 m), reducing sugar (5.84%), non-reducing sugar (4.06%), the maximum number of fruit/ tree (234.52), fruit weight (175.25g) and fruit yield/ tree (40.92 kg), respectively. The treatment having foliar spray 1.5% urea and 0.6 % zinc sulphate proved the second best in respect of these parameters.
