Influence of Granular Biostimulants on Growth and Yield Characteristics of Rice (Oryza Sativa) in New Alluvial Zone of West Bengal, India

Abstract

Rice (Oryza sativa), the primary food source for over half of the global population, is critical to food security but faces productivity challenges from suboptimal fertilizer use and associated environmental degradation in India. Addressing these issues necessitates innovative strategies that enhance crop performance while maintaining ecological balance. Biostimulants, known for their role in enhancing nutrient efficiency and crop resilience, offer a promising solution for optimizing fertilizer use and improving soil health. This study evaluates the efficacy of AGMA Bio Stimulant Granules on the growth, yield, and soil health of rice during the kharif season of 2023 at Bidhan Chandra Krishi Vishwavidyalaya, Kalyani, West Bengal. A randomized block design with eight treatments and three replications was employed, including combinations of AGMA granules with 100% and 80% recommended NPK doses. Results demonstrated significant improvements in growth parameters, yield attributes, and soil nutrient availability with AGMA application. Treatments T2 and T5, integrating AGMA granules with 100% and 80% NPK, respectively, achieved the highest grain yields, with T5 showing a 19% yield increase over the control. Soil health indicators, including organic carbon and available nitrogen, phosphorus, and potassium, improved significantly, while electrical conductivity decreased. The study concludes that AGMA Bio Stimulant Granules enable a 20% reduction in NPK fertilizer use without compromising yields, underscoring their potential to support sustainable and environmentally friendly agricultural practices.
