Rice (Oryza sativa L.) is a principal staple food, with significant production worldwide. In 2021, rice covered 161.77 million hectares globally, with India as the second-largest producer. For sustained output, rice (Oryza sativa L.), a major crop around the world, needs balanced fertilization. Overuse of fertilizers degrades the soil, requiring the use of bio stimulants as an alternative. This study evaluates AGMA Foliar (Kazuki Gold/Yoshi Gold) and AGMA Energy on rice cultivar IET 4786 (Satabdi) during the kharif season of 2021-22 at C-block farm, Bidhan Chandra Krishi Vishwavidyalaya, Kalyani, Nadia, and West Bengal. A randomized block design with seven treatments and three replications was used. Treatments included AGMA Kazuki Gold and Kazuki Energy applied at various stages. AGMA treatments significantly enhanced plant height, dry matter, grain count, and yield. Results indicated that T3 treatment (Kazuki Gold applied twice at 25-30 and 40-45 DAT) achieved the highest plant height (93.00 cm), dry matter (983.66 g m^-²), grain count (180.05 grains panicle^-1), and grain yield (5.26 t ha^-1), with statistical significance confirmed by F-tests at 5% level. T6 treatment (AGMA Foliar (Kazuki Energy) showed comparable results. Chlorophyll content was also highest in T3. Control plots consistently showed the lowest values. The study emphasizes the effectiveness of AGMA Foliar bio stimulant applications, which significantly improve rice growth, yield, and nutrient efficiency. It highlights their potential as sustainable agricultural inputs and suggests optimal application stages for maximizing benefits.
