Agronomic Practices and Intercropping Systems

Agronomic Practices and Intercropping Systems is a research topic within Agronomy and Crop Science. Science Explorer counts 31k research works in it since 1950. 19.5% of them reached the world's top 10% most cited for their field and year.

This cluster of papers explores the practice of intercropping, where two or more crops are cultivated together in the same space, and its impact on agricultural productivity, soil nutrient management, crop diversity, and sustainability. The research emphasizes the role of rhizosphere interactions, nitrogen fixation, and resource use efficiency in enhancing crop yield stability and promoting agroecological practices.
