The concept of critical nitrogen (Nc) concentration can be implemented to diagnose in-season plant nitrogen (N) status for optimizing N fertilizer management. The Nc dilution curves have been established for rice (Oryza sativa L.) grown in different climatic regions, yet no attempt has been made to develop the Nc dilution curve for double cropping rice regions. This study was undertaken to deve...
The food supply is being increasingly challenged by climate change and water scarcity. However, incremental changes in traditional cropping systems have achieved only limited success in meeting these multiple challenges. In this study, we applied a systematic approach, using model simulation and data from two groups of field studies conducted in the North China Plain, to develop a new cropping ...
Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...

Residual effect of straw biochar on grain yield and attributes in a double rice cropping system subtropical China | Rujie Lv, Yong Wang, Qiuju Yanhua Zeng, Qingyin Shang Agricultural Journals
The sustained stability of the arable land replanting index is crucial to national food security strategy. exploration temporal and spatial changes in great significance for agricultural development evaluation. This study investigates China’s from 2010 2019 using MODIS NDVI image data, S-G filtering, quadratic differentiation methods. results show that there are significant difference...
The Nigerian rice sector has made remarkable improvement in the last decade as production has increased significantly thereby reducing the gap between domestic supply and demand. In the last three decades, rice imports make up greater proportion of Nigerian imports as rice forms a structural component of the Nigerian diet. Past government inconsistent policies were not successful in securing go...
