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.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10134J. Environ. Sci. & Natural Resources, 4(2): 51-54, 2011
