Buried archeological features show up as crop marks that are mostly visible using high-resolution image data. Such data are costly and restricted to small regions and time domains. However, a time series of freely available medium resolution imagery can be employed to detect crop growth changes to reveal subtle surface marks in large areas. This paper aims to study the classical Chinese settlem...

Through the website of International Water Management Institute, the referenced evapotranspiration (ET0) was found which was calculated by the meteorological data during 1961-1999 from 147 stations in Sichuan Province. Further, according to the crop coefficients of rice, maize, wheat, rape, the water requirements (ET) of main crops were estimated by using Food and Agriculture Organization (FAO)...

The aim of this study was to evaluate life cycle environmental impacts associated with the generation of electricity from biogas produced by the anaerobic digestion (AD) of agricultural products and waste. Five real plants in Italy were considered, using maize silage, slurry, and tomato waste as feedstocks and cogenerating electricity and heat; the latter is not utilized. The results suggest th...

Abstract Maize is the most important crop grown in South Africa, but yields can be severely reduced by extreme high summer average temperatures and low precipitation, potentially adversely affecting both domestic consumption regional food security exports. To help understand manage climate risks to Southern Africa it essential quantify present-day likelihood magnitude of extremes Africa’s maize...

efficient use of inputs and energy resources is one of the most important principals of sustainable agriculture. for this purpose, water and energy productivity of irrigated agroecosystems of major crops in kermanshah province were evaluated. the data was collected via questionnaire through face to face interview of 180 farmers of this province during summer 2010. results showed that water prod...

Nitrogen (N) is an essential nutrient widely used in maize crop production. The application of a high N rate commonly practiced by growers as "guarantee" optimal growth and yield. However, excessive nitrogen consumption can cause wastage, negatively impact plants, adversely affects the environment. This paper reports on supply leaf characteristics maize. Maize was grown experimental plot Depart...

Maize and soybean intercropping is a cereal-legume pattern that not only increases grain yield but also improves the nutritional value of silage. Experiments were conducted in summer season to compare composition forage silage quality mono-cropped maize intercropped maize-soybean harvested at two stages maturity. The main treatments one sole crop (SM) four patterns (one-row one-row (1M1S), two-...

The North China Plain is an important summer maize production region in China. Investigating spatiotemporal variation patterns of precipitation during the growing season will guide prevention droughts and floods ensure food production. Daily data from 1960–2020 were used to analyze changes precipitation, examine migration barycenters, quantitatively effects ENSO (El Niño-Southern Oscillation) w...
