Abstract:
Rice (Oryza sativa L.) is one of the world's most essential and reliable food crops. The current global population is 7.3 billion people, with an estimated increase to 8.5 billion by 2030. As a result, it's expected that the world's need for grains would treble. It remains challenging to boost rice production levels, nevertheless. Integrated Nutrient Management (INM), a system of agronomy, uses both organic and inorganic fertilizer sources. INM's main objective is to use as little chemical fertilizer as possible. It also helps to boost revenue and reduce environmental risks. Nutrient conversion, microbial activity, and nutrient absorption are all regulated by plant roots. The root zone is hence prone to INM practice. Additionally, it increases the activity of bacteria. By employing INM technique, it is feasible to limit the disease infestation while regulating the amounts of potassium, nitrogen, and other essential elements. To increase soil organic carbon and production, apply organic manure along with the necessary amount of fertilizers. On the basis summarized results, it can be concluded that integrated use of nutrients viz., 50% recommended dose of NPK and Zn through chemical fertilizers and 50% N equivalent farm yard manure provided higher yield of scented rice which was comparable to 100% recommended NPK and Zn through chemical fertilizers alone.
