Response Of Soybean Growth In Sandy Coastal Soil To Seaweed Compost And Biochar Application

Abstract The coastal area is sub-optimal land which poor in nutrients. Therefore it necessary to add organic matter increase nutrients content. research that has been conducted aims determine the effect of seaweed compost and biochar application on soybean growth sandy soils. was arranged a Completely Randomized Design consisting two factors. first factor dose compost, namely 0, 20, 40, 60. second giving biochar, without biochar. data were analyzed using Analysis Variance, if there significant difference, tested with Duncans Multiple Range test at 5% level. results showed interaction between significantly increased rate plant height. Biochar dry weight pod number. Seaweed only root weight. number nodules, length, harvest index not affected by
