Abstract: An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Bangladesh during the period from November 2013 to March 2014 to study the effect of different types of organic manure (no organic manure, cowdung, compost and litter) and mulching on (non-mulch, water hyacinth, rice straw and black polythene) the growth and yield of carrot. The experiment was conducted in a Randomized Complete Block Design with three replications. Application of organic manure and mulching significantly influenced the growth and yield of carrot. Cowdung resulted in the highest gross yield (39.05 t/ha) whereas, the plants received no organic manure produced the lowest for the same (33.03 t/ha). The highest gross (39.12 t/ha) and marketable (35.79 t/ha) yield was obtained from the black polythene mulch while the lowest was obtained from non mulched plot. Cowdung with black polythene mulch produced the highest yield (42.75 t/ha) followed by that of application of litter with black polythene mulch (41.46 t/ha). The lowest (32.00 t/ha) was recorded from the control.
