Effect of Integrated Nutrient Management on the yield performance of T. amanrice

From June to November 2022, we conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, researched how T. aman rice variety cv. BRRI dhan71’s yield performance changed when subjected to integrated nutrient management (INM). The experiment consisted of the following treatments- control (no manure and fertilizer) (T1), the recommended dose of inorganic fertilizer for the cultivars (T2 ), tricho-compost @ 5 tha-1 (T3), tricho-compost @ 2.5 tha-1 + 50% less of recommended doses of NPKS (T4), cowdung @ 5 tha-1 (T5), cowdung @ 2.5 tha-1 + 50% less of recommended doses of NPKS (T6 ), vermicompost @ 5 tha-1 (T7 ), vermicompost @ 2.5 tha-1 + 50% less of recommended doses of NPKS (T8), bone powder @ 5 tha-1 (T9), bone powder @ 2.5 tha-1 + 50% less of recommended doses of NPKS (T10). A three-replica Randomized Complete Block Design (RCBD) was used to set up the experiment. At full maturity, the crop was harvested and data was recorded on many characteristics. The experimental results demonstrated that the yield contributing features and yield of BRRI dhan71 were significantly impacted by integrated nutrition management. The tallest plants (PH) (105.67 cm), maximum total tillers hill-1 (TT) (11.41), maximum effective tillers hill-1 (ET) (9.55), maximum grain panicle-1 (GPP) (118.36), maximum grain yield (GY) (6.48 tha-1), maximum straw yield (SY) (7.55 tha-1), higher biological yield (BY) (14.03 tha-1) was found from T4 treatment. Tricho compost @ 5 tha-1 produced the second highest GY (6.05 tha-1) followed by GY (6.04 tha-1) obtained from T6. On the other hand, the lowest GY (4.07 tha-1) was recorded from T1, and also lowest PH (94.55 cm), minimum GPP (81.61), lowest SY (4.58 tha-1) and lowest BY (8.65 tha-1) were also recorded from T1. Research shows that INM has a significant impact on yield contributing traits and yield of BRRI dhan71.
