Abstract
The guava has tendency to bears flowers and fruits throughout the years but quality of fruits is highly influenced improper crop management practices and bahar season. The fruits of ambe bahar is poor in quality due to lack of nutrients availability and irregular orchard management practices. To carry out this new strategy to sustain the quality of guava through combination of nutrients and growth regulators, the present study was carried out during 2018-19 in 20-years-old orchard on mrig bahar season using foliar application of zinc sulphate (0.5%), borax (0.5%), GA3 (50ppm), and NAA (40ppm) 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 50ppm GA3 significantly increased the leaf nutrient composition (1.09 % leaf N, 0.014 % leaf P, 0.89 % leaf K, 28.50 ppm Zn and 23.70 ppm B). The qualitative parameters of guava fruits also increased by borax and GA3, over untreated control.
