Effects of different fertilizers on growth and yield components of Maize (Zea mays L.)

Abstract

A field experiment was conducted at the Demonstration Farm- College of Agricultural Studies, Sudan University of Science and Technology, Shambat during the Winter Season 2018\2019, to investigate the effect of foliar, DAP and their combination on growth and yield of maize (Zea mays).The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replication .The maize variety used was (Hudeiba2) .The treatments consist of three type of fertilizers: Di- ammonium phosphate (DAP) 120.Kg\ha, foliar (Micro nutrients') 240ml\ha, DAP with foliar, untreated control was used as comparison between treatments , parameters studied included : (plant height(cm), number of leaves per plant, leave area(cm2), stem diameter(cm), Dry weight(g), yield components (cob length(cm) cob diameter(cm) number of rows per cob, number of kernels per raw, number of kernels per cob, hundred grain weight(g), weight\plant(g). The results showed that foliar combination with DAP had significant effect on all parameters studied as compared to the control, it increases plant height by 31%,number of leaves 9%,leaf area 36%,stem diameter 44%, dry weight 207%, cob length 40%, cob diameter 14% number of kernels per row 51%, number of kernels per cob57%,weight plant 99%, except hundred grain weight effected by DAP it increases 28%, there were no significant different among fertilizers treatments on number of rows per cob.
