Abstract


Kentang This study aimed to examine the effect of Ascophyllum nodosum seaweed extract as a biostimulant on vegetative growth and physiology of curly chili (Capsicum annuum L.) Lado F1 variety. Research was conducted using a Completely Randomized Design (CRD) with four dose levels: 0 g (P0), 50 g (P1), 100 g (P2), and 150 g (P3) per polybag with three replications. Application was performed once at transplanting by mixing the extract into the growing medium. Data were analyzed using ANOVA (α=5%) followed by Tukey's HSD test. Results showed no significant effect on plant height, leaf number, root length, fresh weight and dry weight. Photosynthetic rate, transpiration, respiration, and final available N and P increased significantly with increasing dose. Wilting was observed in P2 and P3 treatments, presumably caused by the hydrophilic properties of polysaccharide compounds inducing osmotic stress in 30-day-old seedlings. Treatment P1 (50 g) showed the best vegetative response with the highest dry weight (23.34 g) and harvest weight (34.76 g).
