Response of Dwarf Cavendish banana to nitrogen fertilization on heavy clay soils

D.H. Dawood¹, A.A. Salih¹ and I.A. Ali¹


Abstract:

Cultivation of banana in Sudan extended to the heavy clay soils of the Central Clay Plains, which are inherently low in nitrogen and organic matter. A six years study was undertaken to determine optimum nitrogen requirements of Dwarf Cavendish banana on these soils. Seven nitrogen levels were compared on three plant crops ,and three first ratoons. The response to N application was similar in the six seasons of the study, indicating that application of 138 g N/mat is the optimum level. This corresponded with leaf lamina N content of 3.30/0. Potassium leaf content was reduced with higher N applications. Maximum yields were attained when leaf lamina content of nitrogen and potassium were equal, indicating the importance of balanced fertilization on these soils.
