Effects of plant population and row spacing on yield and components of yield of navy beans ( Phaseolus vulgaris L.)

Navy beans, cv. ‘Sanilac’, were grown in rows 0.2 m and 0.4 m apart, and at 48, 71, and 104 mm within rows. Number of seeds per pod and 100‐seed weights were not affected by the treatments used. Pods per plant and yield per plant were inversely correlated with yield per ha. Yield per ha generally increased with increasing plant density, especially with a decrease in row width, and the highest yields were obtained with the closest spacing in the narrow rows.
