An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from June to November 2013 to study the effect of frequency of weeding and integrated nutrient management on the growth and yield of transplant Aman rice (cv. BRRI dhan49). The experiment consisted of five weeding regimes viz. control (no weeding), one weeding at 15 DAT, two weedings at 15 and 30 DAT, three weedings at 15, 30 and 45 DAT and application of herbicide (Manage 10 WP) and five nutrient management viz. BRRI recommended chemical fertilizers, cowdung at 10 t ha-1, poultry manure at 5 t ha-1, 50% BRRI recommended chemical fertilizers + cowdung at 5 t ha-1 and 50% BRRI recommended chemical fertilizers + poultry manure at 2.5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. We found that the morpho-physiological characteristics, yield contributing characters and yield of transplant Aman rice were significantly influenced by weeding regime and integrated nutrient management.
