Mean numbers of leaves recorded from maize fertilized with cow dung, N.P.K and the control, taken at weekly interval for four months are as shown in Table 1. Result at one week after sowing did not show significant variation in mean number of leaves counted on maize grown from cow dung. N.P.K and on those that did not received fertilizer at all. At two weeks after sowing numbers of leaves was significantly higher in maize plants that were treated with cow dung and N.P.K than the control. Number of leaves at fourteen weeks after sowing was highest for N.P.K and lowest for the control. Maize grown with N.P.K are significantly higher number of leaves compared to the other treatments where there was also significantly higher number of leaves on maize treated with cow dung than the control, similar results was obtained at four weeks after sowing. Mean stem diameter at one week after sowing result showed that maize was significantly thicker when fertilized with N.P.K compared to those treated with cow dung or those that were not treated at all (Table 2). Application of cow dung also produce plant with significantly thicker diameter than those that did not
