Growth and Yield Parameters of Triticale as Influenced by Methanol Foliar Application Under Water Stress

Triticale is mainly grown for feed grain, and biomass production for thatching straw and common human utilization. A combined analysis with split plot layout in two years of 2016 and 2017 with 5 replications was used to evaluate yield and yield components of triticale under different methanol concentrations and irrigation managements in Isfahan, Iran. Irrigation treatments consisted of irrigation on the basis of 70%, 80%, 90% and 100% crop water requirements, and methanol treatments as foliar application on the basis of 15% methanol concentration, 30% methanol concentration and control treatment (0%). Methanol application influence a hundred grain weight was significant. The maximum plant height, number of tillers, LAI, LAD, a hundred grain weight, grain yield, biological yield, harvest index and protein content was achieved in irrigation on the basis of 100% crop water requirement. The maximum plant height, number of tillers, LAI, LAD, one hundred grain weight, grain yield, biological yield, harvest index and protein was obtained in 2017. Foliar methanol application with 15% concentration had obtained the maximum plant height, LAI, LAD, a hundred grain weight, biological yield, SPAD and protein percentage. The results of this experiment suggest that methanol can aid in alleviating the effects of drought stress on triticale in climatic condition of Isfahan. It is concluded that triticale cultivars performed superior in 2017, with 15% concentration of methanol application and irrigation on the basis of 100% crop water requirement.
