ABSTRACT
Seven different substrates were prepared by mixing red soil, humus and river sand in different volume ratios and the growth and yield of Amorphophallus muelleri bulbils in different substrates was investigated. The growth of A. muelleri seedlings were tracked during the reproductive period, with measurements taken of indicators such as petiole length, petiole basal diameter and leaf size during the late period of leaf expansion. Number of surviving plants, weights and sizes of corms, and leaf bulbils were recorded after lodging. The results showed that there were differences in the physical and chemical properties of the seven substrates, but all met the growth requirements of A. muelleri. T1 (river sand), T2 (river sand humus 11), T3 (humus), and T7 (river sand humus red soil 111) had higher emergence rates, reaching 95 %. T4 (humus red soil 11) and T7 had better growth, with larger petiole and leaf sizes than other substrates. T3, T4, and T7 had higher yields, with a bulbil yield of 0.30 t hm-2 and a corm yield of 22.06 t hm-2. Compared to the use of a single substrate, whether river sand, humus, or red soil, the proportional mixture of the three test materials improved the physical structure and chemical composition of the substrate, contributing to the growth of A. muelleri. T7 (river sand humus red soil 111) was was found to be the best nursery substrate for A. muelleri.
