Development of a Sterile Charcoal Charcoal Media Model for Producing Potato Seeds (Solanum Tuberosum L.) Quality Granola Varieties

The long-term goal is to increase productivity and quality of potato seedlings (Solanum Tuberosum L.) granola varieties (quality assurance) with this innovation in cultivation technology with a sterile media and fertigation system. Potato cultivation using cultivation technology that is controlled by the growing media and the system of providing nutrition to plants can: (1) increase production (number of tubers per tree), (2) improve the quality of potato tubers (size and number of tubers of tubers), (3) seed potato tuber quality according to seed standards, and (4) quality assurance of seed potatoes (certified seed). The scope of the study are (1) identification of physical and chemical characteristics of husk charcoal as a sterile planting media, and (2) optimization of fertilizer and nutrition systems through the fertigation system in the cultivation of seed potatoes group G0, G1 and G2 to produce quality seed potato tubers and meet the standards as seeds.
The 2020 research is a continuation of the PSNI grant research funded in 2018 and 2019. The 2020 research activity is a study of the characteristics of rice husk charcoal as a planting medium and an optimal study of seedling potato growth in the rice husk growing media. The characteristics of husk charcoal include: (1) porosity, (2) ability to retain water, and (3) ability to bind micro and macro nutrient elements. Study on the quality of potato plant growth can be seen from the parameters: (1) depth of root and potato tuber development, (2) biomass weight of potato plant parts (roots, stems, leaves and tubers), (3) number of stolons that develop into potato tubers and (4) the number of potato tubers included in the seed potato tuber class.
The results of the 2020 study in the form of the potential of husk charcoal media to produce quality tuber potato tubers were used as the foundation for a 2021 study. The 2021 study focused on manipulation of growing media thickness, and implementation of a fertigation system that supports cultivation. These two manipulated parameters aim to obtain a cultivation model that produces quality potato tubers.
