- Abstract
This study aims to determine the growth of sesame plants that applied biochar organic matter on coastal sandy land. The coastal sandy land area of Indonesia is large enough. It is known as one of the marginal lands that have low productivity due to dominant soil constituent material of sand (>80%) so that it affects the availability of water and plant nutrient negatively. To improve the water-holding capacity, an applied technology is urgently needed so that it can be used as a growing material of sesame. A novel technology through the use of specific biochar, activated coconut shell charcoal, was proposed. Due to its functions in optimizing growing medium, improving soil properties physically, chemically, and biologically as well as in holding water and providing nutrients, the used biological charcoal would work as biological soil amendments. It is expected that biochar can be continuous sources for plant needs. The experiment was factorial design laid out in Randomized Complete Block Design involved 14 treatments with three replications consisting of combinations of seven charcoal applications and two sesame varieties. The data were subjected to analysis of variance and Tukey's Honestly Significant Difference test were used as a post-hoc analysis (p<0.05). The experimental results showed that the optimum plant growth was obtained from the application of coconut shell charcoal at a dose of 10 ton/ha combined with chicken manure at a dose of 30 ton/ha, such as tallest in height, highest net assimilation rate, and had most flowers.
