Effect of Different Levels of Methanol on Spring Planting Potato Under Fertilizer Manegement

In order to study the different levels of methanol foliar application on spring potato under experimental fertilizer management in 2016 in a training farm in Hirmand, split-plot experiment was conducted in a completely randomized block design with three replications. Experimental treatments consisted of 7 levels of fertilizer including 100% NPK fertilizer vermicompost manure nano fertilizer a combination of 50 percent NPK + 50 percent vermicompost 50 percent NPK + 50 percent manure Manure and 50% NPK fertilizer + 50% of nano fertilizer were the main factors and different levels of methanol at four levels (0 10 20 and 30 volumes) as a minor. The results of analysis of variance of the test data showed that the interaction of fertilizer management and methanol foliar application had a significant effect on all traits except day to 50% flowering day to day full coverage day to tuber mature and carbohydrate of the tuber. The results of the comparison of the mean interactions showed that in the application fertilizer and nano of combined with 20% volumetric methanol consumption the highest large tuber and total yield (28.05 t.ha-1) were obtained. Also highest amount of carbohydrates and the lowest amount of catalaze and peroxidase were obtained from this treatment. It can be concluded that for increasing and improving the quantitative and qualitative properties of potato the use of fertilizer and nano of combined with 20% volumetric methanol solution is recommended.
