Embedding the Spatial Heterogeneity of the Agricultural Landscape into Crop Model Parameters to Refine Sub-Regional Yield Predictions

Bregaglio, Simone; Ginaldi, Fabrizio; raparelli, elisabetta - 2022

Assimilating remote sensing data into crop models has unrivaled potential to enhance the accuracy of yield forecasting systems. The main benefit is the increased adherence of the simulations to observed vegetation dynamics related to farmers management and environmental drivers. Here we propose...

Rainfall Variability and Drought Incidences During Crop Growing Season in Selected Stations of Hadiya Zone, Ethiopia : Implication for Rainfed Wheat Crop

Geleta, Dame Yadeta; Abate, Melkamu; Birhanu, Shimelis - 2022

Ethiopian economy relies on Agriculture, but it is highly dependent on rainfall. Rainfall is highly varying spatially and temporally affecting cropping pattern and productivity. Drought incidences and prolonged dry days during crop growing season are the leading challenges of agricultural...

Simultaneously Improving Yield and Nitrogen Use Efficiency in a Double Rice Cropping System in China

Xu, Zhuo; He, Ping; Yin, Xinyou; Struik, Paul C.; Ding, … - 2022

The Nutrient Expert system (NE) has been proposed to improve yield and nitrogen (N) use efficiency (NUE) in the double rice cropping systems in China. However, the advantage of the NE system has yet to be quantified experimentally. A four-year field experiment was conducted in a double rice...

Effects of Nitrogen Fertilizer Rate and Plant Density on Short-Season Cotton Yield, Nitrogen Use Efficiency and Soil Fertility Using 15n Tracing Technique

luo, zhen; Hu, Qiuyue; Tang, Wei; Wang, Xiaowen; Lu, Hequan - 2022

Straw returning has been widely used as nitrogen (N) reduction measure in the North China Plain in recent years. But, little is known of the optimal plant density and N application rate of cotton under straw returning by now. In the present study, a short season cotton SCRC66 was used to study...

Appropriate Bandwidth Achieved High Yield Via Shrinking Maize Intraspecific Competition in an Additive Maize-Soybean Strip Intercropping

Liang, Bing; Ma, Yanwei; Shi, Kai; Chen, Guopeng; Chen, Hong - 2022

Maize-soybean strip intercropping has the advantages of alleviating the contradiction of arable land in China, improving the utilization rate of resources, high yield and sustainability. The key to exert these advantages is to stabilize the maize yield. However, interspecific interactions...

Regulating Plastic Film Mulching on Soil Temperature, Moisture and Functional Bacteria Enhances Winter Wheat Yield in the Loess Plateau of China

Zhao, Xiaodong; Qin, Xiaorui; Li, Tingliang; Gao, Huizhou; … - 2022

Ridge furrows with plastic film mulching (RP) and flat soil surfaces with plastic film mulching (FP) are two main film mulching methods in the Loess Plateau of China. Our previous study indicated that FP could improve wheat yield more effectively than RP, although the reason remains unclear. The...

Optimization of Sowing Date and Irrigation Schedule of Maize in Different Cropping Systems for Grain Mechanical Harvesting in the North China Plain

Wang, Jintao; Dong, Xinliang; Qiu, Rangjian; Lou, Boyuan; … - 2022

The increasing population, water scarcity, and labor cost demand more high-yield, water-saving, and efficient maize production. Grain mechanical harvesting, the quality of which is mainly influenced by grain moisture content, can improve the efficiency and decrease the harvest cost of maize...

Long-Term Film Mulching with Manure Amendment Increase Crop Yield and Water Use Eﬃciency But Decrease the Soil Carbon and Nitrogen Sequestration Potential in Semiarid Farmland

Zhang, Fangfang; Wei, Yanan; Bo, Qifei; Tang, An; Song, … - 2022

Plastic ﬁlm mulching and gravel mulching in combination with fertilization are widely used to increase crop yields and water use efficiency (WUE) in arid and semi-arid areas, but soil surface mulching may stimulate soil organic carbon (SOC) mineralization, therefore, ﬁlm mulching with manure...

Evaluation of the Concentration-Response Relationship between Film Antitranspirant and Yield of Rapeseed (Brassica Napus L.) Under Drought

Xiang, Jie; Vickers, Laura; Hare, Martin; Kettlewell, Peter - 2022

Drought can cause large yield losses of rapeseed ( Brassica napus L.), particularly during the flowering stage. Effective methods of crop management are required to improve the tolerance to drought. Film antitranspirants (AT) help to reduce water loss by forming a waterproof layer to block...
