Effect of deficit irrigation on nitrogen accumulation and capsaicinoid content in Capsicum plants using the isotope 15N

Tilen Zamljen et al.

Summary: Greenhouse production of chilies requires constant irrigation and fertilization to maintain high yield and quality. Deficit irrigation techniques are being developed to address decreasing water availability due to climate change. Nitrogen uptake in chili plants can be hindered under deficit irrigation, affecting growth and yield. This study emphasizes the importance of nitrogen fertilization and irrigation techniques in optimizing chili fruit production and quality.

Optimizing irrigation and fertilization at various growth stages to improve mango yield, fruit quality and water-fertilizer use efficiency in xerothermic regions

Guangzhao Sun et al.

Summary: The study found that the factors influencing fruit yield and water use efficiency were irrigation amount, fertilization rate at the fruit expansion stage, and fertilization rate at the flowering stage, while the factors influencing water, vitamin C and carotenoid contents in fruit were irrigation amount, fertilization rate at the fruit ripening stage, and fertilization rate at the fruit expansion stage. Additionally, the factors influencing soluble solids and total sugar contents were irrigation amount, fertilization rate at the fruit ripening stage, and fertilization rate at the flowering stage.

Effects of irrigation and fertilization on grain yield, water and nitrogen dynamics and their use efficiency of spring wheat farmland in an arid agricultural watershed of Northwest China

Yue Li et al.

Summary: Inappropriate irrigation and nitrogen application can lead to low water and nitrogen use efficiency and severe NO3--N leaching in spring wheat fields. Adjusting irrigation depth and nitrogen application levels can improve soil water and nitrogen status, increase grain yield, and enhance water and nitrogen use efficiency. By optimizing irrigation and nitrogen fertilization, it is possible to achieve higher yields, economic benefits, and environmental sustainability.

Modeling and assessing water and nitrogen use and crop growth of peanut in semi-arid areas of Northeast China

Zhenyu Huang et al.

Summary: Water shortage and poor soil fertility are the main barriers to the sustainable development of peanut production in the semi-arid areas of Northeast China. Understanding the dynamics of soil water-nitrogen and crop water/nitrogen use is crucial for developing effective water and nutrient strategies. This study used an agro-hydrological model to simulate soil water and nitrogen status, as well as peanut growth, and found that the optimal irrigation amount for peanut cultivation in this region is 80-97 mm.

Effect of mineral N fertilizer and organic input on maize yield and soil water content for assessing optimal N and irrigation rates in Central Kenya

Stephen Okoth Aluoch et al.

Summary: This study assessed optimal nutrient and irrigation management practices for maize in central Kenya using field experiments and modeling simulations. The combination of fertilizer and manure resulted in the highest yield, while the combination of fertilizer and straw resulted in the highest soil water content. The model successfully predicted grain yield and changes in soil water content in different treatments, revealing the importance of soil moisture during the grain-filling stage.

Effects of different cropping systems on ammonia nitrogen load in a typical agricultural watershed of South China

Jie Jiang et al.

Summary: The excessive application of agricultural irrigation water and chemical fertilizer has led to non-point source pollution, which needs to be addressed for sustainable development. This study focused on the effects of different cropping systems on NH3-N pollution in the DRB and proposed a critical threshold for NH3-N emission. The findings suggest that crop rotation can reduce NH3-N load, and planting sequence affects NH3-N load to some extent.

Optimizing N-fertigation scheduling maintains yield and mitigates global warming potential of winter wheat field in North China Plain

Sunusi Amin Abubakar et al.

Summary: This study showed that scheduling 50% of nitrogen fertilizer as basal and 50% as topdressing through a drip fertigation system can significantly reduce greenhouse gas emissions and increase yield in winter wheat production. This method is recommended for sustainable wheat production with reduced risk of global warming in the North China Plain.

Interaction effects of irrigation and nitrogen on the coordination between crop water productivity and nitrogen use efficiency in wheat production on the North China Plain

Tianyang Ye et al.

Summary: This study investigates the effects of irrigation and nitrogen management on water consumption and crop yield in wheat production. The results show that increasing nitrogen application improves soil water utilization and reduces irrigation dependence, while irrigation increases crop water consumption. Furthermore, there is a significant positive relationship between crop water productivity and nitrogen use efficiency-yield.

Effects of drip irrigation nitrogen coupling on dry matter accumulation and yield of Summer Maize in arid areas of China

Liang Ma et al.

Summary: The study found that under the condition of irrigation at 3750 m3/hm2 and nitrogen application at 306.5 kg/hm2, maize plants showed optimal dry matter accumulation and yield performance, while increasing the irrigation level to 4500 m3/hm2 and nitrogen rate to 444.5 kg/hm2 resulted in decreased maize yield. The stepwise regression model for predicting maize yield revealed that GRavg had an extremely positive correlation with maize yield.
