Double furrow and single furrow planting and its effect on seed yield of common bean (Phaseolus vulgaris L.)

Abstract

Planting systems influence crop response in the final product. The objective of this research was to determine the influence of the double furrow planting system and single furrow planting on bean (Phaseolus vulgaris L.) seed yield. The research was carried out during the dry season in the period from February to April 2019 at the bean experimental and development center La Compañía of the Nicaraguan Institute of Agricultural Technology, located in San Marcos, Carazo, Nicaragua. La Compañía is located at an altitude of 470 meters above sea level with an average temperature of 24 °C and annual rainfall between 1 200 and 1 500 mm. A paired plot design was used, comparing plot A (double furrow) with plot B (single furrow). The statistical analysis was a Student's t-test. The cultivar used was INTA Rojo Extrema Sequía, generated by the Nicaraguan Institute of Agricultural Technology. The treatments were two planting systems, the first with a double furrow with 80 cm between rows and 40 cm between rows, the second with a single furrow at 60 cm between rows; both with 12 seeds per linear meter. The variables evaluated were number of pods per plant, number of grains per pod and yield in kg ha^-1. There are no statistical differences in yield and its components, so it is concluded that yield and yield components are similar regardless of the planting system.
