The following points highlight the top two methods used for the estimation of crop evapotranspiration. The methods are: 1. Experimental Method 2. Theoretical Methods. 1. Experimental Methods: Estimation of ETo can be made using the formula: ETo = Kpan × Epan Where ETo is the reference crop evapotranspiration in mm/day, Kpan is a coefficient called […]

Article shared by :
In this article we will discuss about the total water requirement in growing a crop, with the help of a suitable formula. The water that is required to irrigate a field or plot of land growing the particular crop not only has to satisfy the evapotranspiration needs for growing the crop, but would also include […]
Variation of Crop Water Requirement | Irrigation | Agriculture
Article shared by :
In this article we will discuss about the need for variation in water requirement of crops, with the help of a suitable diagram. The total water need for various plants is known as delta. However, in planning the supply of irrigation water to a field crop, it is essential to estimate the water requirement of […]
