Effects of integrated plant nutrient supply system (IPNS) on growth, yield, and performance of rice (Oryza sativa L.)

The Integrated Plant Nutrient Supply System (IPNS) offers a sustainable approach to enhancing crop productivity by combining organic, inorganic, and biological sources of nutrients. This study investigated the effects of IPNS on the growth, yield, and overall performance of rice (Oryza sativa L.) under field conditions. A field trial was conducted at agriculture research farm of Shri Durga Ji Post Graduate College, Chandeshwar, Azamgarh during Kharif season of 2024-25 under randomized block design with multiple treatment combinations including chemical fertilizers, farmyard manure, green manure, and biofertilizers. Key growth parameters such as plant height, tiller number, and leaf area index were measured, along with yield attributes like panicle length, grain number, and grain yield. The results suggested that IPNS significantly enhanced vegetative growth and yield attributes when compared to sole chemical fertilizer application. Among the treatments, the integration of 50–75% recommended dose of fertilizers (RDF) with organic and biological inputs yielded the best performance in terms of productivity and nutrient use efficiency. The findings underscore the potential of IPNS in achieving sustainable rice production by improving crop yield and maintaining soil health. The study concluded that IPNS not only enhances rice yield but also contributes to soil health and long-term sustainability, making it a viable strategy for integrated nutrient management in rice cultivation.
