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

Effect of heat–moisture treatment on digestibility of different cultivars of sweet potato (Ipomea batatas (L.) Lam) starch
Different heat-moisture levels were applied to native starches from different cultivars of sweet potatoes available in Sri Lanka (Wariyapola red, Wariyapola white, Pallepola variety, Malaysian variety and CARI 273) to study the digestibility level. Samples were treated with 20, 25, and 30% moisture at 85°C and 120°C for 6 h and in vitro starch digestibility was tested with porcine pancreatin en...

Peptic ulcer is one of the most prevalent gastrointestinal disorder, commonly occurs in developed countries. The present work was carried out to evaluate antiulcer effect of Ipomoea batatas (L) dietary tuberous roots. The Ethanolic extract of Ipomoea batatas (EEIB) was prepared by dynamic maceration for 7 days at room temperature using 70% ethanol (V/V). The antiulcer activity was evaluated...
متن کاملDisentangling the Origins of Cultivated Sweet Potato (Ipomoea batatas (L.) Lam.)
Sweet potato (Ipomoea batatas (L.) Lam., Convolvulaceae) counts among the most widely cultivated staple crops worldwide, yet the origins of its domestication remain unclear. This hexaploid species could have had either an autopolyploid origin, from the diploid I. trifida, or an allopolyploid origin, involving genomes of I. trifida and I. triloba. We generated molecular genetic data for a broad ...
