Answer: Your corn may need more nitrogen fertilizer. Corn loves nitrogen so add lots of composted manures in spring and sidedress the corn with 10-10-10 when it's 4' high and again at tasseling to stimulate large ears to grow. Your peas probably had powdery mildew last year that caused them to dieback. It was cool and wet in early summer and powdery mildew loves those conditions.
