Pengaruh Populasi dan Kedalaman Tanam terhadap Pertumbuhan dan Hasil Garut (Maranta arundinacea L.)

This study was conducted to determine the optimum spacing and optimum depth of planting to growth and yield of arrowroot. This research was conducted at Experimental Field of Agriculture Faculty, Sebelas Maret University on Jumantono, Karanganyar. This research was conducted utilizing Randomized Completed Block Design (RCBD) with two treatment factors of plant spacing and depth of planting. Plant spacing consists of 3 levels, including J1 (30x30 cm), J2 (30x40 cm) and J3 (30x50 cm). Depth of planting consists of 2 levels which are K1 (10 cm) and K2 (20 cm). Data were analyzed by DMRT (Duncan’s Multiple Range Test) at 5% level. The results showed that spacing of 30x50 cm have a higher on plant height variables, tuber length, and tuber weight each plant. The depth of 20 cm gives a higher yield on the number of tubers per plant and tuber weight per plot variables. Both treatments have no significant interaction on growth and yield
