The debate surrounding organic versus inorganic fertilizer application in agriculture has long been a topic of discussion among researchers, farmers, and policymakers. Both types of fertilizers have their advantages and disadvantages, and the choice between them depends on various factors such as crop type, soil conditions, and environmental considerations. Organic fertilizers, derived from natural sources such as compost and animal manure, provide nutrients to plants slowly as they decompose, contributing to long-term soil health and fertility. On the other hand, inorganic fertilizers, also known as chemical fertilizers, contain concentrated forms of essential nutrients and provide readily available nutrients to plants, promoting rapid growth and high yields. However, excessive use of inorganic fertilizers can lead to soil degradation and environmental pollution.

Numerous studies have compared the effects of organic and inorganic fertilizers on crop yield, quality, and soil health. Research has shown that organic farming systems can achieve comparable or even higher yields than conventional systems using inorganic fertilizers while enhancing soil organic matter content and carbon sequestration. However, the choice between organic and inorganic fertilizers depends on various factors, and integrated nutrient management approaches, which combine organic and inorganic fertilizers, Offer a balanced approach to nutrient supply while minimizing environmental impacts.

The combined application of organic and inorganic fertilizers in agriculture offers a promising strategy to improve produce quality while reducing the chemical load in the soil. Research studies have demonstrated that integrated nutrient management optimizes nutrient availability to plants, resulting in improved yield and quality. By judiciously combining the benefits of both types of fertilizers, farmers can achieve sustainable cultivation practices that ensure higher yields, better quality produce, and long-term soil health.

Turmeric holds a significant position in Indian agriculture, both culturally and economically. India is the largest producer, consumer, and exporter of turmeric globally, contributing substantially to the spice's global market.

This article reviews the findings of experiments conducted at various location and agro-climatic condition to assess the combined application of organic and inorganic fertilizers on yield and quality characteristics of turmeric crop. The overall results indicating that the combined application of organic and inorganic application not only increase the yield but also improve the quality parameters like curcumin, essential oil content and antioxidant activity in turmeric. These findings highlight the importance of adopting INM strategies to enhance turmeric production sustainability and quality in a different agro-climatic regions.
