Effect of Color Pod and Growing Media on Germination and Growth of Indigo (Indigofera tinctoria L.) Seeding

Abstract

Indigo (Indigofera tinctoria L.) is family of Leguminosae and economic importance as a source of indigo dye. Indigo seed maturation is not simultaneously. These experiments were 2 experiments; experiment 1 was testing for germination and vigor seed of indigo from 3 different colors pod. Completed Randomized Design (CRD) was designed using 4 replications and 3 treatments as followed green-brown pod, brown pod and black pod. The results indicated that seed form brown pod showed highest germination and vigor seed were 35.75 % and 7.66 % and black pod with the lowest germination of 22.00 % (P<0.05). Experiment 2 was investigated the various medias for germination and growth of Indigo seedling. The experiment was set as Random Complete Block Design (RCBD) with 3 treatments and 3 replications; treatment 1 peat-moss (control), treatment 2 soil : rice husk charcoal : manure (1:1:1,
v/v) and treatment 3 soil : coir dust : manure (1:1:1, v/v). The results showed that germination and growth of indigo seedling with peat-moss gave significantly of germination, seedling height, leaves number, root height and fresh weight compared with other treatments (P<0.01). The germination were 69.00 %, seedling height were 9.55 cm, leave of number were 6.30 leave /plant, root height were 9.99
cm and fresh weight were 0.76 g/plant
