Abstract
A field experiment was carried out to study the effects of inorganic nitrogenous fertilizer and organic cowdung manure on growth and yield of carrot. Three different levels of urea along with three different levels of cowdung were employed in the investigation following randomized complete block design. The result revealed that the application of 150 kg N ha-1 as urea was found suitable for maximum gross and marketable yield (47.35 t ha-1 and 39.0 t ha-1, respectively), while 15 t cowdung ha-1 showed better gross and marketable yield (38.13 t ha-1 and 30.42 t ha-1 , respectively). Regarding the combined effect, the combination of 150 kg N ha-1 and 15 t cowdung ha-1 resulted in the best performance in gross and marketable yields (51.22 t ha-1 and 43.41 t ha-1, respectively). The net return (TK. 211142 ha-1) and benefit cost ratio (4.61) were maximum in the treatment combination of 150 kg N ha-1 in the form of urea and 15 t cowdung ha-1.DOI: http://dx.doi.org/10.3329/jbau.v10i1.12012J.

Highlights
Carrot (Daucus carrota L.) is a highly nutritious cool season root crop
A large number of scientists have studied the effect of inorganic nitrogenous fertilizer on growth and yield of carrot
At harvest the highest plant height (48.06 cm) was obtained when inorganic nitrogenous fertilizer was applied at the rate of 150 kg N ha-1 which was due to the fact that inorganic fertilizer released nutrients quickly and supplied adequate plant nutrients for better vegetative growth of the carrot plant
Summary
Carrot (Daucus carrota L.) is a highly nutritious cool season root crop. It contains appreciable amount of carotene, thiamin, riboflavin and iron (Sharfuddin and Siddique, 1985). Production of carrot in Bangladesh could be increased significantly through increase of per hectare yield. This can be done in many ways, of which the most important one is the judicious application of different fertilizers and manures. Application of different manures (Cowdung/Musturd oil cake) increases the yield of carrot. A large number of scientists have studied the effect of inorganic nitrogenous fertilizer on growth and yield of carrot. No scientist has studied the effect of cowdung on growth and yield of carrot. The present study was undertaken to study the effect of inorganic nitrogenous fertilizer and organic cowdung manure on growth & yield of carrot
