Abstract
The productivity of beans is increased by selecting the best cultivar and applying fertilizers according to the needs of the plant. In addition, the application of high-yielding cultivar and N fertilizers with the right dosage could be used to increase the yield. Therefore, the objective of this study is to determine the effect of nitrogen sources on the growth and yield of two bean cultivars. A 5 × 2 factorial treatment was used in a randomized block design with three replications. The first factor is the Perkasa and Lebat-3 cultivar, the second is organic and inorganic nitrogen fertilizer, namely control, urea 100 kg ha-1, as well as 10, 20, and 30% concentrations of liquid organic fertilizer from leucaena leaves. The results showed that the use of liquid organic fertilizers derived from leucaena could be used as an alternative to nitrogen fertilization. Furthermore, the 20% concentration treatment produced the highest number of trifoliate leaves (8.81 leaves) and dry weight (4.52 g). Based on the results, the use of 20% liquid organic fertilizer with Perkasa cultivar showed the best effect on the number of pods per plant (13.38), and yield (846.67 kg ha-1). The technology of liquid organic fertilizers from leucaena leaves could be recommended for bean organic production.
