Response of Bread Wheat Varieties (Triticum aestivum L.) to Irrigated Water Quality

Abstract

This study was conducted to investigate response of four bread wheat varieties (Iraq , Ibba 95 , Ibba 99 and Sham 6) to irrigated water quality (wastewater and fresh water). The study was included field experiment conducted in two locations, the first in Multaka-Al-Hawija district-Kirkuk, while the second was in Kirkuk city center . RCBD design in split plot with three replicates was used in the study, the main plots represented by the varieties while the water quality occupied the sub plots . The results showed that the Iraq variety was superior in yield component in both locations and single plant yield in Multaka location, wastewater irrigation treatment was superior in traits No. of days to maturity and plant height in two locations, No. of spike/plant and No. of spikelets/spike in Kirkuk location . Ther wase a significantly interaction between varieties and water quality in most traits were studied in two locations . Multaka location was superior in traits : plant height, No. of spike/plant, 1000 grains weight and plant grain weight . This study illustrate that Iraq and Ibba 99 varieties had a good response to water quality and there wasn't any negative effective for wastewater on all studied traits .
