A field experiment was conducted at the Agronomy Research Field, Department of the Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during Aman season (June to December) 2016 to evaluate the growth, yield and yield attributes of aromatic rice (cv. Tulshimala) under the fertilization of cowdung (organic manure) and zinc (micronutrient). The application of different levels of cowdung and zinc fertilizers considerably increased the number of total tillers hill-1, number of productive tillers hill-1, panicle length, test weight (g), grain yield hill-1 (g), straw yield hill-1 (g), grain yield (t ha-1), straw yield (t ha-1), and biological yields over control. However, the treatment combination of CD1Zn2 i.e. 10 t ha-1 cowdung and 12 kg ha-1ZnSO4 along with other recommended doses of inorganic fertilizers produced the highest grain yield (2.79 t ha-1) and straw yield (5.80 t ha-1) over other treatments.
