Effect Of Coconut Biochar Biochar On The Growth And Productivity Of Odot Grass (pennisetum Purpureum Cv. Mott)
Effect of Coconut Shell Biochar on the Growth and Productivity of Odot Grass (Pennisetum Purpureum CV. Mott)
Introduction
The use of biochar from coconut shells has been proven to have a significant impact on the growth and productivity of odot grass (Pennisetum purpureum CV. Mott). This study aimed to investigate the effect of coconut shell biochar on the growth and productivity of odot grass. The study was conducted from July to October 2023 in Greenhouses and the Research Laboratory of the Faculty of Agriculture, University of North Sumatra.
Methodology
The method used in this study is a Completely Randomized Design with four treatments and five replications. The treatment given is in the form of coconut shell biochar with different doses, namely: B0 (control, 10 tons/ha, using manure), B1 (10 tons/ha), B2 (15 tons/ha), and B3 (20 tons/ha). The observed variables include the number of leaves, plant height, fresh weight production, and dry weight production.
Results
The results showed that the application of coconut biochar had a very significant effect (p <0.01) on the number of leaves, plant height, and fresh weight production. Meanwhile, a significant effect (p <0.05) is seen in the production of dry weight of odot grass. B3 treatment with a dose of 20 tons/ha or equivalent to 78.4 grams per polybag shows better results than the treatment with a lower biochar dose, which is 39.2-58.8 gr per polybag.
Discussion
Biochar is an organic material produced through the process of pyrolysis of biomass, in this case coconut shell, which is rich in carbon. Giving biochar into the soil can significantly improve soil quality. This is caused by its ability to improve the physical, chemical, and biological properties of the soil. BioChar is able to increase water retention capacity, improve soil aeration, and increase the availability of essential nutrients for plant growth.
The use of Biochar in this study shows that higher doses tend to give better results, especially in terms of growth in the number of leaves and plant height. This is in line with the findings in the field that the carbon content in Biochar functions as a source of energy for soil microorganisms, which in turn can improve the process of decomposition of organic matter and natural fertilization.
Conclusion
The results obtained in this study also showed that Biochar can be an alternative that is more environmentally friendly compared to the use of chemical fertilizers. Excessive use of chemical fertilizers can result in a decrease in soil quality, pollution, and ecosystem damage. Therefore, the application of biochar in plant cultivation, especially odot grass, can be an effective solution in increasing productivity while maintaining soil health.
Recommendations
Taking into account the results of this study, it is important for farmers and farmers to explore the use of BioChar as part of a sustainable agricultural management strategy. In addition to increasing productivity, the use of Biochar can also improve environmental conditions and support more sustainable agricultural practices. It is hoped that further research can deepen understanding of the mechanism of work of biochar in the soil and variations of their effects on different types of plants.
Future Research Directions
Further research is needed to investigate the long-term effects of biochar on soil health and plant productivity. Additionally, studies on the optimal dosage and application method of biochar for different types of plants are necessary to maximize its benefits.
Limitations of the Study
This study has some limitations. The study was conducted in a controlled environment, and the results may not be applicable to field conditions. Additionally, the study only investigated the effect of biochar on odot grass, and further research is needed to investigate its effects on other types of plants.
Implications of the Study
The findings of this study have significant implications for sustainable agriculture. The use of biochar can reduce the need for chemical fertilizers, improve soil health, and increase plant productivity. This can lead to more sustainable agricultural practices and reduce the environmental impact of agriculture.
