Abstract

Increasing the YIELD of crops, especially corn, as the third most important cereal in the world and our country in terms of economy and consumption is particularly important. ORGANIC FERTILIZERS, as a natural input that produces humus and other organic residuals with no harmful side effects on environment, can be effective in enhancing the YIELD of SILAGE CORN, especially in the different environmental conditions. In order to investigate the effect of NITROGEN from both chemical and organic sources a study was conducted in a randomized complete block design with three replications at the Agricultural Research Station of KHOY in 2012. Experimental treatments were comprised of different types of fertilizers including urea in top-dress and spraying applications, micro-elements Librel BMX, liquid fertilizer developed for corn, and three types of ORGANIC FERTILIZERS; KN25 HumTak, KN60 HumTak and KN30 HumTak with 2.5, 6 and 30% of organic matter, respectively, which were sprayed on the leaves. All treatments were applied at the recommended concentrations either in soil (urea) or on leaves three times in 10-day intervals. Five characteristics of the plants including plant height, stem diameter, and dry weight of whole plant, leaves and stem were measured. Significant differences were observed among the mean of all characters in all treatments with control at P≤0.05. The greatest effect was calculated in mixture of Humtak 6% and top-dress urea with 21.21ton/ha of whole plant dry matter. The lowest effect was observed in the control treatment with 16.52 ton /ha of dry matter. Treatment Humtak 6% + top-dress urea produced the tallest corn plants with height of 296.8 cm. Regarding the results attained it was concluded that using a combination of organic and chemical fertilizers YIELDed higher production of corn in comparison with using only organic or chemical fertilizers.
