Abstract

An experiment was set up to study the effect of irrigation water depth on tomato yield, water charge and net returns. Six different depths of water; 100, 125, 150, 175, 200 and 225 mm designated as treatment A,B,C,D,E and F were applied to six basins of the same size (2m × 2m), respectively at the Geriyo Irrigation Project during the 2011/2012 dry season farming. Tomato (lycpersicon esculetum) Pevabo variety was used as a trial crop. Irrigation interval of 7 days was applied throughout the season. The result shows that crop yield increased with increase in depth of water applied up to an optimum value of 125 mm per irrigation beyond which resulted in decrease in crop yield. An overall average crop yield of 11.7 t/ha was obtained for all the treatments. Highest net returns of $547.68/ha and irrigation water charge of $7.71/ha was recorded for the experiment.  The highest water use efficiency was found to be 8.46X10-3 t/ha/mm found at the 100 mm water depth. Correlation coefficient (r2) between the yield and the amount of water applied was found to be 0.863. Statistically using analysis of variance, the result showed that there was no significant difference among the crop yield at 5% level of significance. This means that crop yield is not influenced by the amount of water applied in the location. Irrigation depth of 125 mm is hereby recommended for tomato in the irrigation project for water saving and yield increase at Geriyo irrigation Scheme.
