Abstract

An experiment was conducted to study the fruit yield and growth rate of guava with the application of different rates of NPK fertilizers along with constant doses of Gypsum and FYM at a private farmhouse located at south-east of Gharo, Sindh – Pakistan during year 2012-13. The fruit yield in terms of plant height (3.08 m), length of fruit (6.92 cm), breadth of fruit (6.01 cm), weight of fruit (110.45gm), number of fruits per plant (375.92), was recorded maximum in plants which were treated with T₉. Same treatment also showed the superior fruit quality traits evaluated in terms of TSS (9.28%), Vitamin C (44.70 mg per 100 ml of juice), and Firmness (5.91 kg/cm²) with lower acidity (0.48 %).
