Integrating soybean variety and biofertilizer management to improve nutrient uptake and yield in coastal regions facing climate change
Article Sidebar
Main Article Content
Abstract
The results showed significant interactions were found between soybean variety and fertilizer treatment for N, P, and K uptake, effective nodule dry weight, shoot dry weight, and root dry weight. The highest N uptake (0.67 mg), P uptake (0.14 mg), K uptake (0.70 mg), and shoot dry weight (36.55 g) were achieved when the tested soybean variety was supplied with the biofertilizer package AMF + Bradyrhizobium + K-solubilizer (P2). In contrast, Anjasmoro receiving Bradyrhizobium + phosphate-solubilizer + K-solubilizer exhibited moderate P (0.13 mg) and K uptake (0.68 mg) but produced the greatest root dry weight (3.81 g). Overall, the results indicate differential varietal adaptability to coastal soils, with biological inputs (biofertilizers/bioenzymes) outperforming chemical fertilizer in improving nutrient uptake, nodulation effectiveness, and plant biomass, highlighting their potential as sustainable inputs for soybean production in coastal environments.
