A.B. M. Sharif Hossain, M.A. Hakim and Justus M. Onguso    

Abstract: A field experiment was carried out to study the effect of manure and fertilizers on the growth and yield of potato in the village Narayanpur under Small Scale Water Resource Sector Development Project (SSWRDSP), Local Govt. Engineering Department, Khulna, Bangladesh. Potato was grown with different combination of manures and fertilizers or without combination. The highest plant height was 71.2 cm and lowest was 46.2 cm at 100 Days After Emergence (DAE) when potato was grown with cowdung + Mustard Oil Cake (MOC) +N+P2O5+K2O and without manure and fertilizers respectively. However, maximum number of shoot per plant, no. of tuber per hill, yield of tuber per hill, tuber size in diameter were 5.0, 9.0, 365 gm and 14.5 cm respectively when potato was grown with cowdung +MOC+N +P2O5 + K2O as compared to that of other combinations. In addition, the highest yield was 24.3 t ha 1 and percent infected plant by late blight disease was highest (20) when potato was grown with cowdung+MOC+N+P2O5+K2O and without manures and fertilizers respectively. Whereas, lowest tuber yield was 12.6 t ha 1 and lowest percent infected plant was 7 in case of without manure and fertilizers and with cowdung +MOC+N +P2O5+K2O, respectively.
