Effect of urea super granule on the performance of cabbage in Young Jamuna and Brahmaputra Floodplain Soils of Tangail

Abstract

A number of experiments were conducted at the Farming Systems Research and Development (FSRD) site, Palima, Tangail for three consecutive years to evaluate the efficiency of USG application in comparison with prilled urea on the yield and yield attributes of cabbage (cv. Atlas-70). There were five treatments, T₁= N₁₉₅ (recommended N dose for HYG, used as prilled urea), T₂= N195 (recommended N dose for HYG, used as USG), T₃=N₁₇₅ (N 10% reduction of recommended N dose as USG), T₄= N₁₅₅ (N 20% reduction of recommended N dose as USG), and T₅= N₁₀₅ (Farmers' N dose used as prilled urea). Treatments T_l-T₄ received recommended dose of other nutrients (P₅₆K₁₆₂S₁₃Mo_0.6CD_3t) and T₅ received P₂₅K₉₀S₀Mo₀CD₅₁ Yield and yield-contributing characters of cabbage significantly responded to the application of USG. The highest head yield (78.1 t/ha) was obtained with the recommended dose of N as USG, and 10% (77.1 t/ha), and 20% (72.0 t/ha) less than the recommended dose of N as USG also produced higher yield than recommended prilled urea-N. Application of USG was found more efficient than prilled urea and the treatment N₁₉₅P₅₆K₁₆₂S₁₃Mo_0.6CD_3t (recommended N as USG for HYG) was found profitable for cabbage cultivation in terms of yield and the treatment N₁₇₅P₅₆K₁₆₂S₁₃Mo_0.6CD_3t (10% N reduction of recommended N dose as USG) was found profitable in terms of economic returns.
