3. Plants grown in the greenhouse and transplanted to the field are sometimes shorter at maturity than plants grown from the same seed sown directly in the field. Very small, immature seeds from ears that are harvested at an early milk stage usually produce plants that grow to normal height and productiveness. This suggests that tall plants that are difficult to pollinate might temporarily be reduced in height advantageously. Possibly better means could be devised to do this, such as bending the plants to the ground in the early stages of growth and allowing them to grow upright. The basal part, could be held down by covering with soil, fastening with a wire staple or tying to adjacent plants.
