Alternate wetting and drying (AWD) is a water management technique, practiced to cultivate irrigated lowland rice with much less water than the usual system of maintaining continuous standing water in the crop field. It is a method of controlled and intermittent irrigation.
The land equivalent ratio can be used whenever more than one type of yield can be obtained from the same area. This can be intercropping of annual crops (e.g. sorghum and pigeonpea) [1] or combination of annual and perennial crops e.g. in agroforestry systems (e.g. jackfruit and eggplant). [3]
A Crop Simulation Model (CSM) is a simulation model that describes processes of crop growth and development as a function of weather conditions, soil conditions, and crop management. [1] [2] [3] Typically, such models estimate times that specific growth stages are attained, biomass of crop components (e.g., leaves, stems, roots and harvestable ...
Crop rotation systems may be enriched by other practices such as the addition of livestock and manure, [17] and by growing more than one crop at a time in a field. A monoculture is a crop grown by itself in a field. A polyculture involves two or more crops growing in the same place at the same time. Crop rotations can be applied to both ...
Field Water Efficiency (%) = (Water Transpired by Crop ÷ Water Applied to Field) x 100; Increased irrigation efficiency has a number of positive outcomes for the farmer, the community and the wider environment. Low application efficiency infers that the amount of water applied to the field is in excess of the crop or field requirements.
field level : based on measurements of CO 2 and water fluxes over a field of a crop or a forest, using the eddy covariance technique [4] Research to improve the water-use efficiency of crop plants has been ongoing from the early 20th century, however with difficulties to actually achieve crops with increased water-use efficiency. [5]
Research is underway statewide to find fruits and vegetables that grow better in heat and humidity and to tap regenerative farming, which uses different crops and methods to reverse climate change ...
A field of sunflowers in Cardejón, Spain (2012) A field of rapeseeds in Kärkölä, Finland (2010) In agriculture, a field is an area of land, enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock. A field may also be an area left to lie fallow or as arable land. [1]
