Abstract
Rice (Oryza sativa L.) is a staple commodity and the primary source of carbohydrates for the people of Indonesia. However, rice productivity in Indonesia remains relatively low compared to other major rice-producing countries. This study aimed to determine the optimal combination of paclobutrazol concentration and NPK fertilizer for improving the growth and productivity of rice plants. The research was conducted from December 2024 to February 2025 in Ngraho Village, Bojonegoro Regency, East Java. A Split Plot Design (RPT) was used with two treatment factors: paclobutrazol concentration (P) as the subplot and fertilizer combination (N) as the main plot. There were 16 treatment combinations, each repeated 3 times, resulting in a total of 48 experimental units. The best treatment combination was Urea (600 kg/ha) + SP36 (300 kg/ha) + KCl (200 kg/ha) + paclobutrazol at 600 ppm. This combination produced the most favorable results in terms of plant height, number of leaves, flowering time, number of panicles per clump, and dry grain yield per hectare. The treatment had a significant effect and is recommended for application in rice cultivation, particularly in areas with similar agroclimatic conditions. Further research in different locations and planting seasons is necessary to evaluate the consistency of these results. Keywords: Nitrogen, potassium, phosphorus, PGRs, retardant
