Special focus: Nutrient management improves yield, quality and nutrient use efficiency of crops: theory and application
Published 28 July, 2022
Nitrogen (N) and phosphorus (P) are essential for the normal growth and development of plants. To obtain high yields, excessive N and P fertilizers were applied in the agricultural production system, leading to ecological deterioration of the environment. With increased demand a for higher crop quality in addition to increased yield, understanding the mechanisms of N and P balance in plants, as well as that of other mineral nutrient elements, to improve nutrient use efficiency (NUE) in the agricultural system is vital. This special focus issue: Nutrient management improves yield, quality and nutrient use efficiency of crops: theory and application, reports the recent progresses in this area. It showcases the responses and improvement of tolerance to nutrient-deficiency stresses in wheat, maize, rice, rapeseed, and millet. The topics include not only molecular technologies but also cultivation methods for improving NUE. These papers enhance our understanding of crop responses to nutrient-deficiency stresses and benefit crop breeding and production for better nutrient management.
