Effect of Different Nitrogen Concentration on Plant Growth, Yield and Quality of Sweet Potato (Ipomea Batatas [L.] Lam) Cultivated in Soilless Culture System

The soilless culture system effectively promotes plant growth by facilitating water and nutrient uptake roots. To increase sweet potato production (Ipomoea batatas), we developed containerized planting in which tuberous roots were grown solid substrates the polybags supplied with a solution through an irrigation system. This study was conducted to investigate effect of different nitrogen concentrations on performance, yield, tuber quality cultivated using experimental setup included five treatments (T1-T5) levels N (0-50-150-200-250 mg L-1), mixed solution, while P K held constant at 150 200 L-1 respectively. After three months cultivation, there significant differences between terms yield quality. Plants 250 showed highest rate including height, shoot leaves fresh weight, number tillers, SPAD values, leaves, diameter tillers compared other treatments. Data also revealed that obtained from plants treated N. Tuber harvested treatment best Brix value, moisture content shape length. Therefore, potatoes is recommended application obtain optimum performance growth, yields,
