Nitrogen (N) is one of the decisive elements for plant growth, crop biomass accumulation,
and yield formation of cereal crops. However, managing N in crop production and …

Improving the tolerance of crop species to abiotic stresses that limit plant growth and
productivity is essential for mitigating the emerging problems of global warming. In this …

Accurately and timely diagnosis of plant nitrogen (N) status is imperative for N fertilization
management and yield prediction of summer maize. This study was aimed to identify the …

Symptoms of nutrient deficiencies in rice plants often appear on the leaves. The leaf color
and shape, therefore, can be used to diagnose nutrient deficiencies in rice. Image …

Intensive vegetable production is commonly associated with excessive nitrogen (N)
fertilization and associated environmental problems. Monitoring of crop N status can …

Nitrogen is an essential nutrient in crop growth cycle and directly affects the photosynthesis
of crops. The leaf chlorophyll content (LCC) and leaf area index (LAI) are important for …

Water scarcity is a major concern for sunflower production in the semi-arid and arid regions
of the world. Potassium (K) application has been found effective to alleviate the influence of …

The development of rice cultivars with improved nitrogen use efficiency (NUE) is desirable
for sustainable agriculture. Achieving this goal depends in part on understanding how rice …

Potassium (K) is one of three main crop nutrients, and the high rate of potash fertilizer
utilization (second only to nitrogen) leads to high prices. Therefore, efficient application, as …

Intensification of greenhouse production is always closely related to massive nitrogen (N)
losses to the environment. Therefore, precisely assessing crop N status and optimizing N …
