The Effect of Rate and Date of Seeding of Small Grains on Yields

Abstract

SynopsisOn irrigated soil in Western U. S., barley sown at rates of 30 to 40 pounds per acre yielded as well as at higher rates up to 140 pounds per acre. Rates of 50 to 60 pounds were adequate for other grains except when sown late. Lighter rates produced stiffer straw, larger heads and kernels, and higher test weight per bushel than the heavier rates. At late planting dates, higher rates helped control weeds and disease. Use of high grade, certified seed is urged for higher yields at lower rates.
