Abstract

Increased productivity of black soybeans continues to be pursued by improving appropriate cultivation technologies, including by providing organic fertilizer. This research aimed to assessing the response of growth and production of black soybean plants to various types of organic fertilizers. The study was conducted in the form of a field experiment in Gowa Regency from March-June 2019. The experiment was designed with a randomized completed block design consisting of four treatments, namely: without organic fertilizer, organic fertilizer from rice straw, organic fertilizer from banana stems and organic fertilizer from gamal leaves. Each treatment was repeated four times, so as to get 16 experimental units. The parameters observed were plant height, number of pods per plant, pod weight per plant and pod weight per plot. The results showed that the administration of organic fertilizers obtained better growth and production of black soybeans. Fertilization with organic fertilizer from Gamal leaves obtained the highest yield of black soybean seeds, 2.46 tons ha-1.

Abstract

Soybean is including a major protein source with a relatively higher consumption rate. Similarly, various efforts have been adopted towards boosting production, including selecting high-yield species and soil fertility improvement using fertilizers. This research aims to increase soybean production by employing the appropriate variety and phosphate fertilizers to improve soil fertility. This experiment was conducted in Takalar, South Sulawesi, between April-July 2019. The split-plot design method was applied with three replications. Consequently, the main plot encompasses the treatment of three varieties, termed Argomulyo, Anjasmoro and Gema, while the subplots relate to phosphate fertilization, comprising three levels, including fertilization with a dose of SP-36 at 50, 100 and 150 kg.ha-1. The results showed that the modifications in variety and phosphorus fertilization significantly influenced soybean production, as Argomulyo obtained the maximum rate of 2.77 t.ha-1, followed by Anjasmoro at 2.45 t.ha-1. Furthermore, phosphate fertilization with a dose of SP-36 at 100-150 kg.ha-1 demonstrated the optimal soybean production as indicated by the maximum productive nodes and pods. Therefore, no interaction was observed between the various species and phosphate fertilization.
