| dc.description.abstract | This research aimed to get optimal plant spacing and proper frequency in ridging to produce the best yields. This research was conducted in randomized complete block design factorial with two factors and three replications. The first factor is plant spacing which consist of six levels: 40 cm x 25 cm, 50 cm x 25 cm, 60 cm x 25 cm, 40 cm x 40 cm, 50 cm x 50 cm, and 60 cm x 60 cm. The second factor is ridging frequencies which consist of two levels: twice and three times ridging. The result of this research showed that plant spacing effected significantly the number of leaves, canopy width, leaf area index, plant dry weight per plant, pods wet weight per plant, pods dry weight per plant, seed weight per plant, number of filled pods per plant, number of harvested plant, pods wet weight plot, pods dry weight plot, and seed weight plot, whereas ridging frequency only effected significantly on plant dry weight per plant. Plant spacing 60 cm x 25 cm and 40 cm x 40 cm produced the best yields and suitable for use in plant cultivation. | en |
