Growth, Yield, and Quality Performance of Swamp Cabbage (Ipomoea aquatica) Cultivars under NFT Hydroponic System

The experiment was conducted to study the growth, yield and quality of swamp cabbage (Ipomoea aquatica) varieties grown with Nutrient Film Technique (NFT) hydroponic system in the net house of the Department of Horticulture, Hajee Mohammad Danesh Science and Technology University' Dinajpur during the period of May-July 2023.The single-factor experiment was run with three swamp cabbage cultivars, BARI swamp cabbage-1 (V1), La procesa swamp cabbage-1 (V2), and Nice green swamp cabbage (V3) under Complete Randomized Design (CRD) with three replications.The average temperature and humidity (daytime) for the study period were 33.86 °C and 91.5%.The results showed that BARI swamp cabbage-1(V1) was better than other cultivars.BARI swamp cabbage-1 (V1) exhibited the highest plant height, leaf area, fresh weight per plant, yield and dry matter percentage, which was found to be 30.33cm, 664.80 mm 2 , 235.03 g, 34.83 ton/ha and 12.33%, respectively.The study examined the performance of two swamp cabbage flowers growing in the same hydroponic system.Nice green (V3) showed the highest number of leaf (31 leaf/plant) and good adaptation increase.It also excelled in SPAD readings and vitamin C content.Nonetheless, results from V2 (LP-1) were only moderate compared to the other two.BARI swamp cabbage-1 (V1) is resulted superior in chlorophyll-a and β-carotene concentration compared to others.So, it was the highest yield and quality performer.The study's findings show the NFT hydroponic system is a suitable system to grow swamp cabbage sustainably especially in the area with limited water and land.The NFT growing aytem that is V1 (BARI swamp cabbage-1) demonstrated best performance for high yield and quality among the tested cultivars.
