An experiment was conducted at the department of Horticulture, Khalsa College, Amritsar(Punjab) during the year 2016-17 to study the role of foliar spray of NAA(50,75,100 ppm), 2,4-D (30,40,50ppm) and Urea(1%, 1.5% and 2%) on yield and quality of guava cv. Allahabad Safeda. The design of experiment was Randomised Block Design (RBD) with factorial arrangement. The results of the study indicated that foliar spray of 50 ppm 2,4-D was found to be the best for increasing yield(47.39Kg/tree). Maximum fruit length at harvest (8.90 cm), fruit weight(203.0 g) were recorded under foliar application of 100 ppm NAA. Various quality parameters namely total sugars(10.46%),reducing sugars(4.99 %), non-reducing sugars(5.47%) and TSS(11.050Brix) were also found to be improved with the application of 50 ppm 2,4-D.
