Abstract

Arrowroot yield can be used as a substitute for rice. Arrowroot tubers can be utilized to meet the needs of carbohydrates. Potassium fertilizer can help the formation of arrowroot tubers and the formation of arrowroot starch. Arowroot are found wildly grown under teak. This research aims to determine the dose of potassium fertilizer and determine the influence of teak leaf debris on arowrrot yield. This research was held from March to September 2016 in the Agricultural Land UNS Jumantono. The research using Randomized Completely Block Design (RCBD) method. Two separate experiments that KCl fertilizer application and the application of teak leaf debris dry. KCl fertilizer treatment given to the arrowroot plant is K0 (0 g-1plant), K1 (2,4 g-1plant), K2 (4,8 g-1plant), K3 (7,2 g-1plant) and K4 (9,6 g-1plant). Debris leaves of teak treatment given the arrowroot plant is A0 (0 g-1plant), A1 (20 g-1plant), A2 (40 g-1plant), A3 (60 g-1plant) and A4 (80 g-1plant). The results showed that the fertilizer KCl 4,8 g-1plant tends to increase arrowroot yields. Adding teak leaf debris 80 g-1plant tends to increase the number and weight of arrowroot tubers.

Abstract

Arrowroot (Marantha arundinacea) is potential plant to be developed in Indonesia. Arrowroot usually grows wild without special treatment so that makes the productivity is low. The purpose of research was to find the suitable planting age and seeds origin of arrowroot. The research was conducted from October 2016 to November 2017 at Experimental Field of Agriculture Faculty of Universitas Sebelas Maret. The research used RCBD (Randomized Completed Block Design) with two factors.The treatment of planting age consist of 3 levels (1 month, 2 months, 3 months) and seeds origin consist of 2 levels (tuber seeds and seed of nursery), each is repeated 4 times with 3 plants each replication. The results showed that the planting age treatment at 1 month of planting age has the better result compared with other treatments in almost every variables observed i.e plant height, number of tillers, tuber lenght, diameter tuber, and tuber weight per plant. The number of leaves,fresh weight plant, dry weight plant, and number of tubers are not significantly different at 1 month of planting age, although the plant is higher. The highest lenght of tuber is 20,5 cm from 2 months of planting age. Tuber weight of planting age treatment reached 31,8–124,9 gram per plant. Seed of nursery showed better results than tuber seeds although not significanly different. Between planting age and origin of seeds was no interaction.
