Narrow Row Corn Yields Depend On High Plant Population
University of Maryland agronomist Dr Rothgeb reports two years of field tests comparing 20, 30 and 40 inch rows with seed rates of 15 680 and 24 120 per acre under irrigated and non irrigated conditions. In 1965 higher populations outyielded lower ones. in 1966 drought favored lower populations in non irrigated plots but irrigated plots with higher populations still outyielded. Narrow rows showed little effect in 1966 when moisture was limiting, suggesting narrow row advantage requires yields well above 100 bushels per acre. The study ends with a quip about people who claim to understand everything.
