Abstract

In order to investigate the effect of the amount of water in subsurface drip irrigation on water use efficiency, performance dates, yield components, and determine the best irrigation in two varieties of palm, a split plot experiment in a randomized complete block design with three replications for the second year experiment (2014-2015) was carried out in Behbahan agricultural Research Station. The main factor was the amount of water in subsurface drip irrigation at three levels based on 75%, 100% and 125% water requirement and sub-plots, the two Variety of Kabkab and Zahedi. in all quantitative traits except water use efficiency such as berry weight and the core, length, number of berries per cluster, date yield and water use efficiency, water levels, there were significant differences between treatments. As 2582.1 cubic meters per hectare consumption of water in the treatment of 75% water requirement in addition to saving water consumption by as much as 28.8 and 45.5 percent compared to 100 and 125% water requirement, The yield of the Treatment Research 6563.6 kg and water use efficiency was calculated as 2.542 kilograms per cubic meter. Two varieties of palm Kabkab and Zahedi also not significantly different in terms of yield and water use efficiency. So that in the hearts 6134.9 kg per hectare yield and water use efficiency was calculated 1.721 kilograms per cubic meter.
