Abstract

Lesser yam (Dioscorea esculenta (Lour.) Burkill) tubers have two important roles in conventional cultivation, as the food as well as the propagation material. The stem cuttings technique is reported can not produce tubers, while micropropagation is less efficient due to the need of large capital, experts, and specific tools. The other hand, farmers are less interested in cultivating this commodity. It has been reported that mini tuber sett can be used for propagation, but it has not been able to explain the growth preferences in each part of the tuber and its effect on yield. The research aims to provide information about the growth preference of lesser yam seedlings from different planting materials and planting techniques and their effects on yields. The research was carried out in Research Center for Biology, LIPI, Cibinong. The experiment was arranged based on split plots with tubers (apical and basal parts) as the main plot and planting position (vertical and horizontal) as subplots. Each treatment was replicated 3 times, with 5 samples for each replication. The results revealed that the apical part produced better shoots and roots than the basal section. The apical dominance of the lesser yam tuber was very high. It is herefore buds that form in the apical tended to grow faster. This section also produced tuber with a better character. With this information, farmers recommended to use planting materials from the apical part of the tuber with horizontal planting position.

Abstract

Polynesian arrowroot (Tacca leontopetaloides), taka, is one of the tuberous plants that distributed near the sea shore to 220 m above sea level. Taka produces two kind of tubers, parent tuber and peripheral tuber. Local people in several locations used taka for forages, cakes, cosmetics and woven. This plant is a minor crop comodity in Indonesia, so it is not widely cultivated yet, and no informations about taka propagation method and its cultivation. Taka produces both tuber and seed for regeneration propose. Aim of this study was to investigate vegetative propagation of taka and its growth pattern. Results showed that propagation by parent tuber required 24 weeks after sowing to produce new peripheral tuber. Material propagation from new peripheral tuber will become new plant. This new plant will produce next generation tuber in 5 months later. Propagation by peripheral tuber (from field exploration) required 24 -28 weeks after sowing to produce next generation plant with leaves and flower stalk directly. Stolon and the next generation tuber were also produced. Taka tuber can be harvested when its leaf turned yellowish.

Abstract

An increasing of population, land conversion, and the behaviour changes in many crops due to global warming could produce a significant negative effect to food security in many countries, including Indonesia. In order to maintain the availability of food, we should find out alternative foods based on corp comodities that can adapt to future agricultural land conditions. One species to be promoted for that purpose is Tacca leontopetaloides (taka). This study was aimed to determine growth characteristics variations of taka in Java and its surrounding small islands through exploration and interview methods. Results indicated that there were two morphological variations of taka based on the canopy colour, namely green and purple. Taka found growing in coastal areas up to100 m above sea level. The light intensity and soil type greatly affected their growth. These plants lived either solitary or in a groups, grow well on sandy soil to clay, under the shade and open areas. Species around taka allegedly contributed in determining taka growth and production. Taka tuber can be an alternative carbohydrate source for supporting food self-sufficiency in coastal communities.
