Influencia de la distancia entre plantas en el surco sobre desarrollo y crecimiento de diferentes caracteres de la planta y rendimiento de maíz colorado "Flint"

Abstract

In this experiment planned to study the effects of different within-row plant spacings on flint hybrid maize, it was found that the various plant spacings (from 5.0 to 95.0 cm between plants) influenced considerably the development and growth of different plant characters (height and diameter of stem, height of ear-insertion, ear number and weight per plant, weight per ear) as well as the yield per plant and per hectare. The higher distances (or low plant density), though favorable for optimum development of individual plant characters, did not result “optimum” for higher yields per hectare, thus the level of plant density giving negative and linear response for yield per plant but quadratic response for yield per hectare. A distance of approximately 25.0 cm between the plants in the row (58–60,000 plants density) resulted the highest yield of over 50.00 quintals per hectare.
