Effect of Soil Enhancer (XXL) and Fertilizers on the Morpho-Physiological and Yield Attributes of Brri Dhan28 (Oryza sativa L.) In Boro Season

The experiment was conducted at the Research Farm of Sher-e-Bangla Agricultural University, Dhaka to find out the effect of soil enhancer (XXL) and fertilizers on the morpho-physiological and yield attributes of BRRI dhan28 in Boro season. The experiment comprised one factor viz. T1= 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 and T8=100% dose of XXL + 75% recommended dose of fertilizer. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Significant variation was observed in different morpho-physiological and yield contributing characters of rice with XXL and fertilizers. Among the different XXL and fertilizers doses, 100% dose of XXL + 75% recommended dose of fertilizer provided the best result of rice with the increased of plant height (20.94%), SPAD value (17.46%), tillers hill-1 (61.84%), leaf area (38.43%), panicle length (8.44%), filled grain panicle-1 (33.91%) and 1000 grain weight (3.75%) over than control. The highest grain yield (7.65 t ha-1) which was (89.83%) higher than that of control treatment. It meant that BRRI dhan28 performed well with 100% dose of XXL + 75% recommended a dose of fertilizer applied.
