Abstract
The field study was carried out to evaluate the effects methanol concentrations and seed inoculation with Azospirillum in water stress conditions. Experiment was conducted using a randomized complete block design with a split-plot arrangement of treatments and four replications. The first treatment factor was two levels of water stress (based on 40 and 70% depletion of available soil moisture)as the main plots. The second treatment factor was methanol concentrations at three levels (0, 14 and 28 % (v/v) methanol) andthe third treatment factor was the absence and presence of seed inoculation with Azospirillumlipoferum Stain 21 bacteriaas subplots.RY(Root Yield), SC(Sugar content), SY(Sugar Yield), WSY(White Sugar Yield), Na, K and N contents,WSC, molasses sugar, alkalite were verified. Results showed a significant different between different concentrations of methanol on RY, SC, SY, WSY, and N contents. The greatest RY (60.01 ton ha -1 ) was observed in plots with 28 % (v/v) methanol spraying. The maximum WSY was found in 28 % (v/v) methanol treatment, followed by 14 % (v/v) methanol spraying (6.97 and 6.46 ton ha-1, respectively). Results also indicated that RY, SC, SY, WSY, Na, N contents, molasses sugar and alkalite were influenced by different levels of irrigation. Normal irrigation had a higher RY than deficit irrigation, 60.63 vs. 47.64 ton ha -1 . Furthermore, WSY was
