KcMod: a crop coefficient model

2010
This Program was written in July 2009 (by R.L. Snyder and A. Swelam), and revised in July 2010 and 2018 (by R.L. Snyder and E. Guerra). It aims to provide a practical tool for crop coefficient calculation according to local climate conditions, for both academic and non academic purposes.

Forage Sorghum Evapotranspiration and Crop Coefficients

5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA, 2010
Forage sorghum, especially brown mid rib (BMR) hybrids, offers attractive silage options in place of corn and has excellent ethanol conversions compared with other forage sorghums. The purpose of the study was to measure the evapotranspiration (ET), yield, forage quality, and water use efficiency of a fully irrigated BMR forage sorghum hybrid grown for

Revising Crop Coefficient for Washington Sate

2013 Kansas City, Missouri, July 21 - July 24, 2013, 2013
Abstract. Water shortages are expected to increase in the future due to the need to grow crops to feed a growing population, the increasing production of bio fuel crops, the desire to protect and restore waterways for fish, the competition for water among different sectors, and water shortages due to climate change effects.

Crop Coefficients for Arizona Landscape Trees

5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA, 2010
Water use of many landscape plants is not only a factor of how much water a plant needs, but rather how much it receives. Previous research has found that desert-adapted trees such as live oak, once thought to be a low water user, will readily consume several times the quantity of water considered necessary for such a plant.

YIELD-BASED, IRRIGATED ONION CROP COEFFICIENTS

Applied Engineering in Agriculture, 1999
Irrigation scheduling is one of the most important tools for developing best management practices (BMPs) for irrigated projects. Proper irrigation scheduling results in the high irrigation water use efficiencies necessary to conserve limited water resources. Information about crop coefficient (Kc), daily reference evapotranspiration (Eto), and daily

Irrigation crop coefficients for lowland rice

Irrigation and Drainage Systems, 1994
Meteorological and lysimetric data for a period of nine years were used to develop crop coefficients for rice grown under lowland conditions in a sub-humid tropical climate in India. The estimated crop coefficients were found to be higher than those values recommended by FAO.

Irrigation Crop Coefficients for Illinois Corn

Transactions of the ASAE, 1989
ABSTRACT Optimum scheduling of irrigations reduces costs, conserves water and reduces the likelihood of water quality problems. Crop coefficients are required for the estimation of daily crop evapotranspiration (ET) that is needed to schedule irrigations. Most crop coefficients have been developed in the Western U.S.

Determination of Crop Coefficient of Tea

Journal of Agricultural Engineering (India), 2009
Crop coefficient of tea was determined based on evapo-transpiration data (1996-2001) using weighing type lysimeter. Weekly reference crop evapotranspiration (ETo) was worked out for the same period by FAO Penman–Monteith (FAO 56-PM) equation using daily meteorological data.

Crop kites: Determining crop-water production functions using crop coefficients and sensitivity indices

Advances in Water Resources, 2016
Abstract The crop-water production function quantitatively evaluates the relationship between seasonal water use and crop yield and is used to evaluate optimal irrigation depth and assess the potential of deficit and supplemental irrigation. A simple and easily applicable methodology to develop crop- and region-specific crop-water production ...

Water use efficiency and crop coefficients of dry season oilseed crops

Agricultural Water Management, 2007
Abstract Eastern India receives higher average annual rainfall (1000–2000 mm) but 80% of it occurs within the June–September (rainy season), whereas the winter season (November–March) is dry. Due to a shortage of soil moisture, most rainfed areas of the region remain fallow during the winter season and cultivation (mainly rice) is confined to the ...
