Effect of population and row spacing on the performance of four corn (Zea mays L.) hybrids

Effect of population and row spacing on the performance of four corn (Zea mays L.) hybrids

Agron. J 61(3): 439-41. Bibl. 13

In field trials in 1966 and '67, 4 early maize hybrids were grown at populations of 30, 000, 45, 000, 60, 000 and 75, 000 plants/ha at each of 4 between-row spacings of 50, 65, 80 and 95 cm. Row spacings did not affect grain yield but each increase in population markedly increased grain yields, except in a dry year when the optimum population was 60, 000.
