Abstract:
A field experiment was conducted at the experimental orchard of CCS Haryana Agricultural University, Hisar, Haryana during year 2020-21 and 2021-2022. In this study 63 guava cv. Hisar surkhatrees planted at a spacing of 6×6 m were subjected to foliar sprays of boron, magnesium and iron at the time of fruit set and again after one month to study the effect of foliar sprays of boron, magnesium and iron on yield and quality of guava. The experiment was carried out in Randomized Block Design with 21 treatments and 3 replications. The foliar sprays of boron, magnesium and iron significantly influenced vegetative characters of guava. Plant height, plant spread, canopy volume, length of lateral branches, length of terminal branches, leaf area and leaf area index were found to be maximum under the treatment T₂₁ [FeSO₄ (0.5%) + H₃BO₃ (0.5%) + MgSO₄ (0.5%)]. However, stem girth was non-significantly influenced by the nutrient sprays.
