Ridge planting and population arrangement and density on dean yield

Abstract

This research was carried out in Araruna, Arara and Lagoa Seca, Paraiba, Brazil, in order to study the following aspects of Phaseolus vulgaris crop: planting system (ridges and flat planting) plant spacing and plants/hill. The treatments were combined in a factorial experiment 2 x 4 x 3 in a randomized complete block design with four replications. Data on final stand, grain production (kg/ha), pods/plant, seeds/pod and weight of 100 seeds were collected. The "ridge planting system" outyielded the conventional "flat planting system" in 200 kg/ha and appeared to have a more stable production over different plant populations tested. The best treatment combination was the "ridge planting" with three plants per hill spaced 20 centimeters, with a production of 1,164 kg/ha. In this spacing, the flat system also gave the highest yield (1,045 kg/ha).
