Abstract
This study aimed to determine the effectiveness of aqueous extract from various plants as an exogenous plant growth regulator (PGRs) in the morphology, growth, and nutrition of C. racemosa. The natural PGRs used were coconut water (CW), shallots and coconut water (AESCW), maize (AEM), moringa leaves and mung beansprout (AEMBS), and E. cottonii (AEEC). A 50g of C. racemosa was soaked on the natural PGRs and was cultivated for 30 days with a sandy mud substrate. The results showed that the soaking of C. racemosa on natural PGRs had a significant effect (P<0.05) on absolute growth, specific growth rate, and nutrient. C. racemosa soaked in aqueous shallot and coconut water showed the best absolute growth (214.32±7.68 g) and SGR (5.55±0.08%/day), meanwhile C. racemosa soaked in coconut water had the best nutrition (protein: 9.54±0.16%; fibre: 1.37±0.21%; and fat 0.42±0.04%). The morphological analysis showed that soaking C. racemosa on natural PGRs resulted in long fronds, bigger stolons, a greener and fresh colour, and more ramulli.
