The Effect of Deficit Irrigation on Seasam Growth, Yield and Yield Components in Drought Conditions on base of sustainable agriculture
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 10
Abstract
In order to determine the best irrigation frequency on economic production of sesame in Jiroft area an experiment was conducted as Randomized Complete Block design with seven treatments in three replications from 2010, for two years. In this experiment treatments were consist of I1) irrigation frequency on the basis of farmer conditions, I2) irrigation frequency after 90 mm evaporation from pan, I3) irrigation frequency after 120 mm evaporation from pan, I4) irrigation frequency after 150 mm evaporation from pan, I5) irrigation frequency after 180 mm evaporation from pan, I6) irrigation frequency after 90 mm avaporation before flowering phase and irrigation frequency after 180 mm evaporation from pan after flowering phase and I7) irrigation frequency after 180 mm evaporation from pan before flowering phase and irrigation frequency after 90 mm evaporation from pan after flowering phase. After harvest, yield (kg/ha) and yield components were measured. Results showed that irrigation frequency treatments had significant effect on yield, yield components, plant height and number of branch. by increasing time distance between irrigation frequency yield, yield camponents and plant growth decreased so that maximum of these parameters obtained from I2. However the most important finding happened in I7, that according to sever water deficiency conditions in area, along with saving 1000 m3/ha water could produce considerable yield after I2,that yield difference between I2 and I7 treatments was 100 kg/ha.
