and 48%; Figure 6-4). The frequency with which crops were planted in gardens was not significantly 

 different between years (x^ = 11.510, d.f. = 10, P = 0.319). 



Gardens typically contained several crops. In 1989, the average number of crops planted per 

 garden was 5.9 (SE = 0.25, n = 150 gardens, range = 1-12 crops per garden; Figure 6-5). In 1990, 

 the average number was 3.9 (SE = 0.47, n = 40 gardens, range = 1-11 crops per garden). The 

 number of crops planted per garden was significantly different between years (x' approximation = 

 13.773, d.f. = 1, P = 0.0002). 



Crop phenologv . Although planted at the same time, seeds in a particular garden may not 

 germinate at the same time or develop at the same rate. This may affect wildlife use of gardens if wild 

 animals select for or against certain plant species or plant parts (e.g., com cob or sweet potato tuber).
