Comparison of different methods in estimating potential évapotranspiration at muda irrigation scheme of Malaysia [PDF]

open access: yes, 2012
Evapotranspiration (ET) is a complex process in the hydrological cycle that influences the quantity of runoff and thus the irrigation water requirements. Numerous methods have been developed to estimate potential evapotranspiration (PET).

Irrigation Scheduling and Fertigation of Pole Tomatoes by Using FAO-56 Penman-Monteith Method

open access: yes, 2013
Fertigation consists of application of irrigation water with plant nutrients to plants. Therefore, both application time and doses of plant nutrients and application time of irrigation and application amounts of water are highly important. Excess watering caused yield reduction because of leaching of plant nutrients below rooting depth and reverse ...
