Effect of foliar spray of zinc sulphate and gibberellic acid (GA3) on growth, yield of guava (Psidium guajava L.) c.v. Allahabad Surkha

Author(s): Kuldeep Singh and Dr. Saket Mishra
Abstract: The present experiment was conducted at Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. Prayagraj during the session 2023-2024. The experiment was laid out in randomized block design with three replications, and the study consists of Ten treatment combinations including control by using “Effect of foliar spray of zinc sulphate and gibberellic acid (GA3) on growth, yield and quality of guava c.v. Allahabad Surkha.”. The best treatment was T9 (Zn 0.35% + GA3 100 ppm) & T8 (GA3 100 ppm) which shows highest values in all the parameters viz., Number of days to anthesis (12), Number of flower/plant (80.44), Fruit set (%) (70.92%), Fruit length (8.22 cm), Fruit weight (g) (182.24 g), Number of fruit/plant (60.11), Fruit yield/plant (12.27 kg). All the treatments were significantly superior in their flowering, fruit yield and quality of guava cv. Allahabad Surkha over control (T0) and (T9). Increase flowering, fruit yield and quality was might be due to the increased duration of fruit quality during winter season.
