Effect of humic acid on the reaction yield and yield components of barley foliar micronutrient fertilizer

To evaluate the effect of foliar application of humic acid on the reaction yield and yield components of barley foliar application of micronutrients, Factorial experiment in a randomized complete block design with three replications in the city Jovin (Hokmabad) was performed. Factors studied include the application of micro-nutrients at levels of tillering, stem elongation, flag leaf emergence, Tillering + stem elongation, tillering and stem elongation + + flag leaf flag leaf emergence and application of humic acid humic acid were both spraying and not spraying. . Foliar application of micronutrients, micronutrient fertilizer was used. The concentration of micronutrients and foliar application of humic acid was 2 per thousand. The results showed that foliar application of micronutrients on all features except for harvest index showed a significant effect. Most plant height and number of tillers per plant with two foliar application of micronutrients barley tillering and stem elongation stage, respectively. The application of micro-nutrients in stem elongation stage and flag leaf emergence, generates the highest number of tillers per plant, panicle length, number of grains per spike, grain yield and vegetable raw barley. . A foliar application of micronutrients in the flag leaf stage, produced the highest grain weight. Effect of foliar application of humic acid on all the features of the study was significant. Application of humic acid, plant height, number of tillers per plant, harvest index, yield and yield components, compared with no application of humic acid significantly improved. Humic acid spraying with micronutrients improve the climate response to foliar application of micronutrients and plant height, harvest index increased compared with foliar application of micronutrients alone. According to the results, two foliar application of micronutrients with humic acid elongation stage and flag leaf emergence to produce the maximum yield in the atmosphere in similar climatic conditions is recommended.
