Study on the use of baby corn stover for soil fertility management was conducted at Kasetsart University, Kamphaengsaen Campus. Supersweet corn DMR No.1 seeds were planted on October 30, 1987. The population of 28, 856 plants per rai were obtained from growing 3 plants per hill in a 50 cm * 30 cm spacing. The representative sample plants were harvested at 50 days. The result showed that most of the average plant weight were of stalk and leaf blades. For the weight of ears, most were of the husk. It was found that most of the nutrients were several times more accumulated in the stover (i.e.stalk, leaf and tassel) than in the husked ear (i.e.ear, husk and silk). Comparing between the income and fertilizer expense that would give plant nutrients equal to that accumulated in those plant parts, selling off only ears with husk was more benificial. In the contrary, selling off corn stover was disadvantageous. Hence, it is recommended that for improvement soil properties especially its fertility, farmers should return corn stovers into the soil rather than selling them off as animal feed.
