Abstract

To study the effect of DEFICIT IRRIGATION on COTTON YIELD, determination of yield function and WATER USE EFFICIENCY, an experiment was conducted based on randomized complete block design (RCBD) with four replications on cotton (Sahel variety) in BayeKola, Agricultural Research Station of Mazndaran Province during 2002 - 2003. Irrigation treatments based on 0, 25, 50, 75, 100 and 125% of water requirement, affected COTTON YIELD significantly (P<0.01). The highest and lowest COTTON YIELD with 1679 and 3099 Kg/ha were obtained from I0 treatment (0% of water requirement) and I3 (75 % of water requirement), respectively; while the highest values of WATER USE EFFICIENCY were belonged to I0 and I1 treatments. There was no yield reduction in I3 with 25% less water requirement. While COTTON YIELD in I2 (with 50% water requirement) was decreased 15%, significantly as compared with I4 (100% water requirement). Thus, full irrigation is not necessary for cotton irrigation in MAZANDARAN PROVINCE, and irrigation with 75% of water requirement could be sufficient.
