Abstract:
The present investigation entitled Effect of pre-harvest chemical treatment on post-harvest quality in guava (Psidium guajava L.) was conducted at college of agriculture, Latur during winter season 2021-2022. The work was conducted at Instructional-cum-Research Farm, P.G. Laboratory, Department of Horticulture, College of Agriculture, Latur, V.N.M.K.V., Parbhani (M.S). Fruit crops selected and research carried out in Randomized Block Design (RBD) with three replications and nine treatments during Kharif season, 2021. Treatment consisted of different concentrations of calcium chloride (1 and 1.5%), calcium nitrate (1 and 1.5%), salicylic acid (500 and 750 ppm) and chelated zinc (0.5 and 1%). The experiment was conducted in Randomized Block Design (RBD) with nine treatments and three replications. Fruits were stored at room temperature up to 9 days in which significant effect of calcium chloride @ 1.5% i.e. T₂ were observed for physical attributes such as maximum yield of fruit (17.76 kg/plant) at harvest, maximum fruit weight (140.94g), fruit specific gravity (1.033 g/cc) at 9^th day of storage at ambient storage conditions, where control treatment was lowest in all parameters.
