KcMod: a crop coefficient model [PDF]

open access: yes, 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.

Seasonal variation of evapotranspiration, Priestley-Taylor coefficient and crop coefficient in diverse landscapes

open access: yesGeography and Sustainability, 2021
Priestley-Taylor equation (PT) and the Penman-Monteith equation (PM) are commonly used methods for regional evapotranspiration monitoring, using the PT coefficient (αa) and PM crop/ vegetation coefficient (Kc).

The Effects of Deficit Irrigation Scheduling on Water Consumption and Water Use Efficiency of Millet in the Northern Shanxi Province

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Millet is a drought-resistance crop and widely grown in the northern Shanxi province of China. The scarce rainfall in these areas means that millet cultivation is mainly rain-fed, which hinders millet growth and compromises its yield ...
