Irrigation Water Productivity and Water use Efficiency of Sugarcane Plants under Drought Conditions (Case Study in Farabi Agro-Industry Lands)

摘要

This study was aimed to evaluate the productivity and performance indexes of sugarcane biomass` irrigation water use, at its growth different ages in 2009-2010 cropping year, in Farabi agro-industry farms. During this study, based on the age, four farms were selected for each plant. These farms had the highest performance among different ones. Performance rate, plant evapotranspiration, and total quantity of irrigation water were determined during the plant growth period and, based on their amounts, irrigation water productivity index and the average water use efficiency were 2/64 to 3/399 kg/m3 and 25/43 to 38/35 kg/ha.mm, respectively.
