The effect of methanol and some micro-macronutrients foliar application on Maize (Zea mays L.) maternal plant on some of morphophysiological characteristics in a subsequent generation

In order to investigate the effect of the foliar application of various combinations on corn maternal plant on some of morphophysiological characteristics in a subsequent generation, an experiment was conducted in the factorial form based on RCBD with three replications during growing seasons of 2009-2011. Treatments were four growth stages Treatments were four growth stages (the 8-10 leaves, the tasseling, the seed-filling, all the stages), seven levels of foliar application (Methanol, Zn, B, Mg, N, Mn, a mixture of all combinations) and control as a separate plot. The analysis of the data showed a significant effect of the combination type of foliar application in different stages on the seed yield, grain filling rate and duration, 100 grain weight, and harvest index in a subsequent generation. The detailed results of the study showed that N-foliar application in all stages had the highest seed yield of a subsequent generation, while Mn-foliar application in all stages it had the lowest effect. Besides, the results also proved that Mg-foliar application in seed-filling stage had the highest grains filling rate whereas foliar application with a mixture of all combinations in tasseling had the highest grains filling duration. N-foliar application in all stages had the highest 100-grain weight. In addition, B foliar application in all stages and tasseling had the highest and lowest harvest index in a subsequent generation, respectively.
