Abstract:

The quality of guava (Psidium gujava L.) is highly laden by improper crop management, which can only be solved by the use of bio stimulants either through foliar feeding of nutrition or growth regulator application. To carry out this new strategy to sustain the quality of guava through the combination of nutrients and growth regulators, the present study was carried out during 2018-19 in a 20-years-old orchard using the foliar application of zinc sulfate (0.5%), borax (0.5%), GA₃ (50 ppm), and NAA (40 ppm) either alone or in combinations, comprised of 9 treatments and 3 replications under randomized block design. The results revealed that plants treated with 0.5% Borax along with 50 ppm GA₃ significantly increased fruit set (64.16 %), fruit retention (56.32%), fruit yield (65.63 kg/plant), and physical attributes of fruits compared to control.
