Farmland surface soil mulching with plastic film is extensively used to enhance agricultural productivity in the Loess Plateau (LP). However, the effect of mulching on the key processes that dominate soil nitrogen dynamics is rarely assessed...

An experiment was conducted at research farm, Agricultural research sub-station, Hanumangarh, a
unit of Swami Keshwanand Rajasthan Agricultural University, Bikaner during Kharif season, 2016 to
study the effect of water and nitrogen application rates...

The intensive winter wheat (Triticum aestivum L.)–summer maize (Zea mays L.) cropping systems in the North China Plain (NCP) rely on the heavy use of mineral nitrogen (N) fertilizers. As the fertigated area of wheat and maize in the NCP has grown...

Soil salinization affects crop production and food security. Mapping spatial distribution and severity of salinity is essential for agricultural management and development. This study was aimed to test the effectiveness of machine learning algorithms...

Irrigated agriculture is the backbone of Central Asian economies and efficient
irrigation management is of crucial importance to the sustainable crop production. The ET-based irrigation scheduling method has potential to replace subjective daily...

This is the second part of a Special Issue on developments and applications of the Soil and Water Assessment Tool (SWAT) related to agricultural water and nonpoint source pollution management at a watershed scale (see Volk et al., 2016 for part I).

The choice of an appropriate crop and cropping systems is essential for achieving
higher yield, profit and resource use efficiencies. Yield, returns and water productivity
are important factors for determining suitability of crops and cropping...

About 41% of the Earth’s land area is classified as dryland wherein the farming system is characterized by approximately 300-500 mm of annual rainfall. The low rainfall, which is not only insufficient but irregular, constitutes a major challenge to...

The key success factors of the olive oil market are the enhancement and stabilization of olive yields, improvement of olive oil quality and reduction of production costs. There is great potential for cost reduction in terms of water saving in olive...

The study on “Evaluation of Cropsyst model for yield and water productivity of clusterbean” was conducted on farmers
field during kharif 2012 at village Mainawali in Hanumangarh district of Rajasthan. The soils of the area are alluvial and
