Abstract:

An experiment was conducted at the Field Research Site of the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur-1706 during November 2011 to March 2012 to study the response of wheat to foliar application of urea fertilizer. Three fertilizer treatments were maintained in the 3m × 2m experimental plots in a Randomized Complete Block Design (RCBD). A non-fertilized control was compared with two foliar fertilized treatments receiving 20 kg ha-1 of N in soil at crop emergence and also received foliar spray of 1% and 2% urea in each time at 36, 53 and 68 Days After Sowing (DAS). Soil Plant Analysis Development (SPAD) value was taken from middle portion of the latest fully developed leaf of tagged plants at 3 day interval from 36 DAS using Minolta Chlorophyll meter upto 89 DAS. Perusal of the data revealed that significant effect was found in total dry matter production, leaf area index and SPAD values for chlorophyll content. Significant increase was recorded in number of effective tillers m-2, spikelets spike-1, grains spike-1, thousand-grain weight and grain yield with foliar application of urea. Foliar application of 2% urea resulted in maximum number of effective tillers m-2, spikelets spike-1, grains spike-1 and grain yield. Maximum thousand-grain weight was recorded from 1% urea spray which was statistically similar to that of 2% urea foliar spray. It was concluded that foliar spray of 1% urea solution at tillering, jointing and booting stages along with 20 kg ha-1 of N at crop emergence helped in enhancing yield and yield components of wheat.
