Effect of Variety and Urea Super Granule on Growth and Yield of Wheat

Abstract

The experiment was carried out at Agronomy Field Lab of Bangladesh Agricultural University (BAU), Mymensingh during the period from November 2009 to March 2010 with a view of finding out the effect of appropriate dose of USG on growth and yield of wheat. Three wheat varieties viz. Shatabdi, Bijoy and Prodip and 6 levels of nitrogen (T₀, T₁, T₂, T₃, T₄ and T₅) were applied as treatments in this study. Among the application of USG on morpho-physiological and growth characters of wheat, the maximum plant height (98.33 cm), number of spikelet (21.33) and sterile spieklet (19.87) were found from V₃T₅. Similarly, V₂T₃ produced the highest no. of spikelet spile^-1 (11.50) and grain yield (2.75 t ha^-1) whereas similar treatment also showed the maximum no of non effective tiller (1.07) with V₁T₃.The treatment combination of V₂T₂ were recorded the highest on 1000-grain yield (51.98 g), no of non sterile spike (2.07) and no of grains spike^-1 (48.87). The highest no of total tiller hill^-1 (5.13) and effective tiller (4.33) were taken from the treatment combinations of V₁T₅. The highest straw yield (4.67 tha^-1) was recorded in V₂T₄.
