Optimum Plant Population of Supersweet Corn

Few studies have been done to determine the range of ideal plant populations for supersweet corn. Ideal plant populations to maximize grain yield of field corn and useable ear yield of sweet corn are well established based on production area, cultivar maturity, soil, and fertility status. For sweet corn ideal plant populations are lower than for field corn because ear quality is a primary consideration. Ideal plant population for the normal sweet corn cultivar Golden Jubilee grown in the Treasure Valley of eastern Oregon and southwestern Idaho is thought to be 25,000 plants per acre.
