| Title : | EFFECTS OF SUBSTRATES ON GROWTH, YIELD AND TUBER QUALITY OF SWEET POTATO CULTIVATED USING SOILLESS CULTURE SYSTEM |
| Abstract : | The soilless culture system effectively promotes plant growth by facilitating water and nutrient uptake by plant roots. To increase sweet potato (Ipomoea batatas) production, we developed containerized planting in which tuberous roots were grown in solid substrates in the polybags supplied with a nutrient solution through an irrigation system. Five combinations of growth substrates were evaluated: 100% coir dust; 100% burnt paddy husks; 70% coir dust + 30% burnt paddy husks; 30% coir dust + 70% burnt paddy husks; and 50% coir dust + 50% burnt paddy husks. The sweet potato plants were harvested 90 days after planting. Plants grown in 100% coir dust gave the best yield compared to the other treatments. They produced the highest tuber yield (2788 g) compared to the plants grown in 100% burnt paddy husk which produced the lowest tuber yield (1174 g). Tubers obtained from 100% coir dust showed the highest Total Soluble Solid (TSS) value (12.1° Brix) and moisture content (76.73%) compared to other treatments. These results showed that sweet potato cultivated in coir dust substrates increased the tubers yield by 2.3 times compared to those grown in burnt paddy husks. Studies revealed that planting sweet potato in 100% or high coir dust substrates increased the plant growth, tuber yield and enhanced tuber quality compared to substrates containing high burnt paddy husk. |
