  This study aimed to develop a cultivation protocol for tomato (Solanum lycopersicum) under 50% shade conditions in protected environments, targeting the mitigation of heat stress effects through the foliar application of Paclobutrazol (PBZ) to regulate plant growth while maintaining optimal yield. Six treatments, T1 (0 ppm, control), T2 (25 ppm), T3 (50 ppm), T4 (100 ppm), T5 (200 ppm), and T6 (400 ppm) were arranged in a Randomized Complete Block Design (RCBD) with five replicates. Foliar applications were conducted at 14-day intervals, and data on vegetative and reproductive traits were collected at corresponding intervals. Statistical analysis was performed using ANOVA, and mean comparisons were conducted via Dunnett’s test at a 5% significance level. The results demonstrated that PBZ significantly influenced vegetative and reproductive parameters of tomato, showing a signifi.. Read More»
