Abstract

The Research was carried out in order to study the effects of different levels of water application in DRIP IRRIGATION on yield and WATER USE EFFICIENCY of GRAPE in Golmakan Agricultural Research Station of Khorasan in 1999. Experimental design was factorial complete randomized block with 4 replicates. The factors were levels of water application (50, 75 and 100% of plant requirements) and DRIP IRRIGATION method (drip and T- Tape). Planting distances were 2 meters and rows distances were 2.5 m. Four rows including 6 trees in each one were selected for treatment. The GRAPE variety namely Soltani that enrooted previously was planted in March of 1999. The irrigation method was surface irrigation in 1999. But Drip and Tape were used in 2000. Water requirements of GRAPE were obtained from national document on water, considering shadow percent in each irrigation. Yild was not considerable during 1999, 2000 and 2001. The combined analysis results of yield in years 2002, 2003 and 2004 showed that there was no significant difference between Drip and Tape irrigation methods. But there was significant difference between different water application levels. The levels of 100, 75 and 50 % of water consumption were located in A, Band C of statistical group by yield of 8.597, 7.707 and 4.827 tons per hectare, respectively. It shows that the yield in 2 levels of 75 and 50 % water consumption decreased by 13 and 43% in comparison with the 100% water consumption level. There was no significant difference between irrigation methods where WATER USE EFFICIENCY was considered but water use percentage showed differences at 1% level. The highest record 75% found by water use with 1.844kg GRAPE/1m3 water efficiency followed by 50 and 100 present with 1.720 and 1.574kg/m3 respectively. It can be reported that WATER USE EFFICIENCY at 75 and 50% water consumption level was about 17 and 9% higher than 100%. According to the results, where shortage of water is not a problem, complete (full) irrigation and where we are facing to the shortage, 75% water use level is recommended with consideration to the yield, water consumption and WATER USE EFFICIENCY. Two irrigation methods are both applicable.
