Effect of chicken manure biochar and water stress on root characteristics and yield of Purslane (Pottulaca Oleracea L.)

Purslane (Portulaca oleracea L.), aside from being known as a weed, is a healthy food that has been highly beneficial to humans as a nutritious vegetable and folk medicine for centuries, and recognized by the WHO as one of the most used medicinal plants. In this study the root characteristics and yi...

Shuadinaly Yusoff S Agriculture (General) Purslane (Portulaca oleracea L.), aside from being known as a weed, is a healthy food that has been highly beneficial to humans as a nutritious vegetable and folk medicine for centuries, and recognized by the WHO as one of the most used medicinal plants. In this study the root characteristics and yield of purslane with biochar application and water stress was analyzed. With 45 polybags used during the study, biochar was added to the planting medium two weeks before planting at rates of 0 t/ha, 10 t/ha and 20 t/ha. One-week old purslane seedlings were exposed to drought conditions by giving different watering intervals of 1 day, 2 days and 3 days. After harvest, the fresh and dry weight of purslane was taken, while the root characteristics, such as total root length, root surface area and root/shoot ratio were taken by WinRHIZO software, as well as soil pH, total nitrogen and total available phosphorus as the soil chemical properties. For plant growth parameters, Treatment B10 (l0t/ha biochar rate) showed the highest value of plant fresh weight (105.78 g) and plant dry matter (9.12 g). While Treatment 1D (1 day watering interval) showed the highest value of plant fresh weight of 115.85 g and plant dry matter of 10.30 g. As for root characteristics, Treatment B10 resulted in the highest value of root surface area, total root length and root/shoot ratio with 676.30 cm2, 2941 cm and 0.19, respectively. For root surface area, Treatment 1D resulted in the highest value with 743.18 cm2, Treatment 3D (3 days watering interval) showed the highest total root length (3399 cm) and Treatment 2D resulted in the highest root/shoot ratio (0.20). Soil chemical properties such as pH and total nitrogen were greatly affected by water stress compared to biochar rate, except for total available phosphorus. However, the results showed that there was no significant interaction between the biochar rate and watering intervals. This study concludes that, biochar had no significant effects on both plant growth and root characteristics due to the short period of application before planting, therefore less nutrients were released into the soil.
