The Effect of Distance from the Tricklers on Soil Salinity and Growth and Yield of Sweet Corn in an Arid Zone1


The effect of the distance between crop row and tricklers on growth and yield of sweet corn, and on soil moisture and salinity was studied. The max yield was obtained when the nozzles were located 5-25 cm from the plants. Less vigorous vegetative development resulted when the tricklers were at a distance of 50 cm. The salt concn in the 0 to 30-cm soil layer increased with distance from the trickle line. Soil water tension was almost constant throughout the irrigation cycle at distances between 5 to 35 cm, it was lower at 0 cm from the tricklers, and markedly higher at 50 cm from the irrigation line.
