Yield Components as Affected by Planting Dryland Maize in a Double-Skip Row Pattern

Abstract

Yield components of dryland maize (Zea mays L.) planted in a double skip-row versus solid pattern were compared at three plant densities in four trials. Ear and kernel characteristics were determined. No row-pattern by-population interaction occurred. Increased yield was because of increased kernel weight, size, and number, whereas decreased yield from skipping rows was due to shorter ears. Increasing plant density reduced ear length and kernel number. Double skip-row planting increased yield by promoting kernel size and weight in semi-arid environments. Skipping two rows and increasing plant density affected yield components that should be considered in making planting decisions.
