摘要

A comprehensive field investigation was conducted during 2022–2023 and 2023–2024 to assess the effect of pruning and foliar feeding on the yield and quality of guava. The experiment was laid out in a factorial randomized block design (FRBD) with 39 treatments and three replications. The pruning treatment P1 (25 cm shoot pruning) exhibited significantly superior performance, with the highest initial fruit set/shoot (9.83), number of fruits/plant (174), fruit retention per shoot (7.93), yield/plant (25.10 kg), and yield/hectare (278.86 q/ha) recorded. Conversely, the lowest values for these parameters were recorded under P0 (no pruning). Among the nutrient treatments, N2 (urea @ 3%) recorded the maximum initial fruit set per shoot (10.14), number of fruits per plant (172), fruit retention per shoot (8.20), yield/plant (27.45 kg), and estimated yield/hectare (304.99 q/ha). With respect to fruit quality parameters, pruning at 50 cm (P2) resulted in the highest total soluble solids (TSS; 11.47 °Brix), ascorbic acid (235.96 mg/100 g pulp), total sugar (9.67%), reducing sugar (5.64%), and non-reducing sugar (4.03%). Similarly, in terms of foliar nutrient application, N6 (zinc sulfate @ 0.6%) had the highest content, followed by TSS (11.46 °Brix), ascorbic acid (245.05 mg/100 g pulp), total sugar (9.73%), reducing sugars (5.69%), and non-reducing sugars (4.04%). Minimum titratable acidity (0.38%) was recorded in N6, whereas the highest acidity (0.44%) was found in the control (N0).
