Resumo-1 N levels (i.e. 164.8 and 163.5 cm, respectively) followed by 90 kg ha -1 N level (161.3 cm). The shortest plants of maize were found in the control plots. The maximum cob length (12.33 cm) was recorded in the sto mp and in the atrazine treated plots while the minimum cob length (9.83 cm) was found in the control plots. Maize gave the greatest grain yield (1.47 t ha -1 ) in the atrazine treated plots and the lowest grain yield (1.24 t ha -1 ) was realized in the control . In addition, the greatest grain yield of maize (1.5 t ha1 ) was found under the 160 kg ha1 N level. The interaction of all the herbicides with 160 kg ha -1 N level had produced the best grain yield of maize. As over all, atrazine was found to be the best herbicide for weed control in maize and the 160 kg ha -1 N level was found to be the best for increasing productivity of the crop.
