A field experiment was conducted during the summer season of 2024–25 at the Instructional Farm, Khudmudi, College of Horticulture and Research Station, Mahatma Gandhi University of Horticulture & Forestry, Durg (C.G.), to evaluate the “Influence of Different Plant Growth Regulators on Yield Attributes of Pumpkin (Cucurbita moschata)”. The experiment was laid out in a Randomized Block Design (RBD) with ten treatments and three replications. Treatments comprised different concentrations of plant growth regulators, namely NAA (50, 75, and 100 ppm), GA₃ (25, 50, and 100 ppm), and Ethrel (100, 150, and 200 ppm), along with a control treatment. The study revealed that application of plant growth regulators had a significant influence on yield and economic parameters of pumpkin. Among the treatments, foliar application of Ethrel at 200 ppm proved most effective, recording the maximum number of fruits per plant (3.25), highest average fruit weight (2.80 kg), maximum fruit yield per plant (8.97 kg), fruit yield per plot (53.80 kg), and total yield (314.61 q/ha). This treatment also recorded the highest economic return with a maximum net profit (Rs. 1,92,418.00) and benefit-cost (B:C) ratio (3.24). These findings indicate that the use of plant growth regulators particularly Ethrel at 200 ppm plays a crucial role in improving both the productivity and economic viability of pumpkin cultivation.
