Abstract
Monsoon crop of guava is hit by fruit fly during July-August that results into huge loss to the producers. Spray of urea and Naphthalene acetic acid (NAA) is used to drop flowers and fruits of monsoon crop to get higher yield of winter crop. This study was carried out at Fruit Orchard of Horticultural Research Station, Bahawalpur during 2015-2017 to determine the optimum concentration of selected chemicals to drop flowers and immature fruits of monsoon crop. Plants with distilled water spray were treated as control (T1). Other treatments included urea @ 5% and 10% (T2 & T3), NAA @ 0.05 and 0.1% (T4 & T5) as 1st spray and repeated the same spray after fortnight, combination of urea (5%) as 1st spray followed by NAA (0.05%) as 2nd spray (T6) or urea (10%) 1st spray followed by NAA (0.1%) as 2nd spray (T7). Consolidated means of parameters over two years’ study indicated that the highest fruit yield (68.6 kg/plant), the maximum weight per fruit (168.3 g), number of fruit/plant (375), pulp content (55.5%), pulp thickness (1.05 cm), total soluble solids (14.3 °Brix), ascorbic acid content (176.7 mg / 100 g pulp) and total sugars (7.6%) were obtained as a result of highest flower drop (96.7%) and fruit drop (76.9%) with lowest fruit set (2.9%) from non-target monsoon fruiting in response to 0.1% NAA (T5) sprayed twice at fortnight interval, proceeded after the application of 0.05% NAA two spray fortnightly (T4). The plants under control remained at bottom with respect to parameters i.e. flower and fruit drop, at top with highest fruit setting in monsoon crop that led to the lowest yield of winter crop.
