EFFECT OF SOIL ENHANCER (XXL) ON THE MORPHO-PHYSIOLOGY, YIELD ATTRIBUTES AND YIELD OF BRRI DHAN 28 IN BORO SEASON

Abstract

The experiment was conducted at the Research field of Sher-e-Bangla Agricultural University, Dhaka during the period from December 2014 to May 2015 to find out the effect of XXL on the morpho-physiological attributes of BRRI dhan 28 (inbreed) in boro season. The experiment comprised of one factor viz. T1= No fertilizer (Control), T2=100% recommended dose of fertilizer, T3= 100% dose of XXL without fertilizer, T4=100% dose of XXL + 100% recommended dose of fertilizer, T5=50% dose of XXL + 50% recommended dose of fertilizer, T6=50% dose of XXL + 100% recommended dose of fertilizer, T7=100% dose of XXL + 50% recommended dose of fertilizer, T8=100% dose of XXL + 75% recommended dose of fertilizer. Significant variation was recorded for data on growth, yield and yield contributing parameters of experimental materials. The maximum plant height, leaf area, number of tillers hill-1, number of filled grains panicle-1 and weight of filled grains plant-1, SPAD value of leaf was found in 100% dose of XXL with 75% recommended dose of fertilizer treatment. The highest 1000 grain weight (22.98 g) was obtain from100% dose of XXL with 75% recommended dose of fertilizer treatment. The highest grain yield (7.65 t ha-1) was obtained from100% dose of XXL with 75% recommended dose of fertilizer treatment. The lowest grain yield (4.03 t ha-1) was obtained from control treatment.
