Persicaria minor locally known as kesum from the family Polygonaceae is a common aromatic herbal plant found in Malaysia. Hydroponic cultivation of kesum using a deep water culture (DWC) system can be an alternative option for kesum growers in increasing crop yields. The deep water culture system is a method in which liquid fertiliser solution is given directly to the plant roots without any medium and water flow. Aromatic compounds such as aldehyde and caryophyllene in kesum have shown nutraceutical and pharmaceutical properties. The study’s main objective was to determine the effects of nutrient solution on the growth, yield and aromatic compounds (aldehyde and caryophyllene) of kesum cultivated using a hydroponic system. Plants were grown under one of four nutrient solution regimes and the experiment was conducted under a side-netted rain shelter. The four treatments comprised 100%, 50%, 25% and 0% strength of the MARDI’s nutrient concentrations typically used in commercial vegetable production. The experiment was arranged in a Randomized Complete Block Design (RCBD) with 4 replications. Plants were harvested eight weeks after planting. Plants grown supplemented with 50% strength of nutrient concentration gave the best growth performance, biomass yield and aldehyde aromatic compound compared to the other treatments. They produced the highest plant height (78 cm), fresh biomass yield (174 g per plant) and aldehyde content (aldehyde C-10: 5.80% and aldehyde C-12: 12.23%). Plants treated with 100% nutrient concentration produced the lowest aldehyde-C10 (0.75%) and aldehyde C-12 (2.11%) but the highest caryophyllene (12.53%) content compared to other treatments. However, plants treated with 0% nutrient concentrations exhibited major nutrient deficiency symptoms and died after 3 weeks of planting. Hence, it can be concluded that the kesum plants cultivated using hydroponics’ deep water culture system supplemented with 50% strength of MARDI’s nutrient concentrations gave the highest plant growth, biomass yields and both aldehyde C-10 and C-12 compound.

Abstract

Persicaria minor locally known as kesum from the family Polygonaceae is a common aromatic herbal plant found in Malaysia. Hydroponic cultivation of kesum using a deep water culture (DWC) system can be an alternative option for kesum growers in increasing crop yields. The deep water culture system is a method in which liquid fertiliser solution is given directly to the plant roots without any medium and water flow. Aromatic compounds such as aldehyde and caryophyllene in kesum have shown nutraceutical and pharmaceutical properties. The study’s main objective was to determine the effects of nutrient solution on the growth, yield and aromatic compounds (aldehyde and caryophyllene) of kesum cultivated using a hydroponic system. Plants were grown under one of four nutrient solution regimes and the experiment was conducted under a side-netted rain shelter. The four treatments comprised 100%, 50%, 25% and 0% strength of the MARDI’s nutrient concentrations typically used in commercial vegetable production. The experiment was arranged in a Randomized Complete Block Design (RCBD) with 4 replications. Plants were harvested eight weeks after planting. Plants grown supplemented with 50% strength of nutrient concentration gave the best growth performance, biomass yield and aldehyde aromatic compound compared to the other treatments. They produced the highest plant height (78 cm), fresh biomass yield (174 g per plant) and aldehyde content (aldehyde C-10: 5.80% and aldehyde C-12: 12.23%). Plants treated with 100% nutrient concentration produced the lowest aldehyde-C10 (0.75%) and aldehyde C-12 (2.11%) but the highest caryophyllene (12.53%) content compared to other treatments. However, plants treated with 0% nutrient concentrations exhibited major nutrient deficiency symptoms and died after 3 weeks of planting. Hence, it can be concluded that the kesum plants cultivated using hydroponics’ deep water culture system supplemented with 50% strength of MARDI’s nutrient concentrations gave the highest plant growth, biomass yields and both aldehyde C-10 and C-12 compound.
