Fertilizer requirements of sweet corn

WEET CORN is the most important truck and canning crop grown in Illinois, and Illinois is the leading state in acreage and total production of this crop.Notwithstanding this prominence of sweet corn as a vegetable crop, comparatively little published in- formation is available concerning the many problems encountered every season in growing it.There is a particular dearth of reliable information in regard to the effectiveness of commercial fertilizers when used with sweet corn.Sweet corn is grown on a commercial scale in Illinois chiefly in certain parts of the central and northern sections of the state, where soil conditions are exceptionally favorable.Canners make a practice of contracting with only the most capable farmers who have good land and who rotate their crops with legumes.In spite of such care- ful choice of growers, sweet-corn yields are not as high as they should be, as is evident upon calculating the theoretical total yield that could be obtained from an acre on the basis of a single ear to the plant.
