Effect of Planting Distance on Yield and Agronomic Characteristics of Red Kidney and Native White Beans in an Oxisol

Abstract

The effect of planting distance on yield and yield components of two field bean varieties (27R, a red kidney bean imported from Trinidad, and Bonita, a selected native white bean) were evaluated in a Coto clay, a Tropeptic Haplorthox. Planting distances included 30, 45, and 60 cm between rows. Mean yield differences between varieties and between planting distances were not significant. However, a field-wide average of around 2200 kg/ha was obtained, a satisfactory yield under prevailing conditions. Plant and pod weight did not differ between varieties, but with the 60 cm distance between rows they were heavier than with 30 cm and 45 cm. Bonita produced more pods than 27R; the lower number occurred with the 30 cm distance. Bonita produced an average of 5.5 seeds/pod; 27R, only 3.8. Both varieties appeared to be free of insect or disease damage.
