Food security is one of the main challenges facing humanity, and increasing crop yields is critical to meet the growing global food demand. Grain production in China has remarkably improved since its founding in 1949, but the growth remains uneven across regions. The goal of this research was to...

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...

Understanding the causes of spatio-temporal variation in crop yield across large areas is an important step forward in closing yield gaps and producing more food and fibre for the growing global population. While there has been much focus on using data-driven models to predict crop yield, there...

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...

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...

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...

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...

Accurate crop evapotranspiration simulation is vital for reasonable irrigation planning. The two-step method for crop evapotranspiration estimation has been widely used for irrigation water demand management. However, in the two-step method, the crop coefficient ( K c ) is typically taken as a...

The potential spreading of antibiotic resistance genes (ARG) into agricultural fields and crops represent a fundamental limitation on the use of organic fertilization in food production systems. We present here a study of the effect of spreading four types of organic soil amendments (raw pig...

Rice is produced in 72% of the departments in Colombia. Recent extreme events have raised concerns about the relationship between weather and rice production, since aproximately 35% of the hectares where rice is grown rely exclusively on rainfall for the crop’s water needs. This study provides...

A 7-year multisite field experiment was performed to assess the relative importance of climate, soil, and microbial properties in crop production in a wheat cropping system under contrasting fertilization management (i.e., continuous organic vs. chemical fertilization). The results showed that...

Fertilizer and seasonal precipitation in dryland crop production is critical for maximizing yield. Low rainfall dryland crop production globally is vulnerable to climatic variability. This work introduces and evaluates previously unconsidered alternative management practices to increase crop...

Farmers in developing countries like Bangladesh face different kinds of rice production risk, which influences yield variability. This study investigates the technical efficiency and production risk of Boro and Aman rice production season in Bangladesh by using stochastic production frontier...
