EVAPOTRANSPIRATION RATE OF RADISH (Raphanus salivus L.) PLACED - INSIDE AND OUTSIDE THE NET HOUSE AT MINDANAO STATE UNIVERSITY- GENERAL SANTOS CITY

The evapotranspiration rate of crops are highly affected by meteorological factors and environmental condition. Thus, this study aimed to determine the following objectives: the evapotranspiration rate of radish for whole cropping season placed inside and outside the net house; the peak evapotranspiration rate; and the difference in evapotranspiration rate of radish placed inside the net house and placed outside the net house in Agricultural and Biosystems Engineering Complex, Mindanao State University —General Santos City. The study used descriptive statistics and Complete Randomized Design (CRD) with two (2) treatments, replicated three (3) times. The treatments were: inside and outside the net house. The data gathered for crop evapotranspiration rate placed inside and outside the net house were graphed and peak ETc rate was determined. The average ETe rate placed inside and outside the net house were 7.82 mm/day and 7.85 mm/day. Peak ETc rate placed inside and outside the net house were 12.9 mm/day. Even though ETc rate placed inside and outside the net house have a difference of 0.03 mm/day, still it is not significantly different at 5% level of significance and also it is almost negligible. Since measurement of evapotranspiration rate of crops are highly affected by environmental factors, it is recommended to measure these meteorological parameters three times daily. Future study may focus on the crop maintenance such as amount of irrigated water and environmental condition such as solar radiation and wind speed. Also, the researcher may set some of these factors as experimental variable
