Corn yields and evapotranspiration as influenced by moisture levels, nitrogen levels, and several climatic factors

Irrigation is most effective when used at the right time and in proper amounts. To make irrigation more efficient, means are being sought for predicting the proper time to irrigate and determining the amount of water required by each crop.

This study was conducted to ascertain the effect of nitrogen levels and moisture levels on the yield and moisture use by corn and the effect of climatic factors such as temperature, solar radiation, wind, sunshine, and humidity on evapotranspiration and evaporation from open pan and atmometers. The ultimate aim is to relate corn yield to certain climatic factors and to explore the possibility of guiding the farmers in scheduling their irrigation practices based on climatic data.
