An experiment “Effect of pruning time, boric acid and potassium silicate on yield and quality of guava (Psidium guajava L.) cv. Lal Bahadur” was carried out at Horticultural Research Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, during the years 2023 and 2024. The experiment was laid out in Completely Randomized Design with Factorial concept having three repetitions and sixteen treatment combinations of three factors. A.) Pruning time (P₁: Last week of April and P₂: Last week of May), B.) Levels of boric acid as foliar spray (B₀: No spray-Control, B₁: 0.4% Boric acid, B₂: 0.8% Boric acid and B₃: 1.2% Boric acid) and C.) Levels of potassium silicate as foliar spray (S₀: No spray-Control and S₁: 4 ml/L Potassium silicate). From the two years of experiment, it can be concluded that pruning in last week of May enhanced the quality parameters and shelf life. In case of levels of boric acid, foliar application of 0.8% boric acid enhanced quality parameters along with shelf life. For levels of potassium silicate, foliar application of 4 ml/L potassium silicate increased quality parameters as well as shelf life.
