Abstract:

Pot experiments were conducted at the net house of Department of Soil Science, Sylhet Agricultural University campus, Sylhet during the period from November 2015 to May 2016 and November 2016 to May 2017 to find out the effect of fertilizer on the growth, yield and yield contributing characters of fine boro rice varieties. Two varieties (BRRI dhan50 and BRRI dhan63) and two fertilizer treatments (NPKSZn recommendation and 50% of NPKSZn recommendation) were included in the experiment. The recommended fertilizer dose was NPKSZn @ 138-22.4-63.5-13.5-1.3 kg ha-1. The experiment was laid out in a two factors Completely Randomized Design (CRD) with three replications and continued for consecutive two years. During 2015-16 the tallest plant (70.65 cm) and the higher no. of tillers hill-1 (13.73) was produced by BRRI dhan63 but during 2016-17 the higher no. of tillers hill-1 (15.54) was produced by BRRI dhan63. The tallest plant (70.86 cm and 57.67 cm) and the highest no. of tillers hill-1 (14.11 and 20.06) was produced due to application of NPKSZn as per recommendation. The higher grain yield of 39.20 g pot–1 and 78.21 g pot–1 and straw yield of 66.86 g pot–1 and 95.18 g pot–1 were recorded from the variety BRRI dhan63. The grain yield was significantly affected due to fertilizer application. The lower grain yield of 41.58 g pot-1 and 56.68 g pot-1 were observed in the NPKSZn fertilizers as 50% of recommendation. The higher grain yield 48.02 g pot-1 and 86.00 g pot-1 were recorded in NPKSZn due to recommended fertilizer application. The highest grain yield was also obtained due to effect of in the interaction of BRRI dhan63 with application of recommended NPKSZn fertilizer.
