Effectiveness of Gandasil D Fertilizer Concentration on Indigofera Seedling Growth in Various Growing Media Compositions

Indigofera sp. is an environmentally friendly source of indigo dye for batik production and a material for livestock industry because this plant potentially serves as a forage protein source. This plant has the potential to be further developed and its cultivation requires quality seeds. Seedling growth is an important factor in achieving maximum productivity. Increasing its growth can be done by providing sufficient nutrients and using appropriate growing media. The results showed that there was an interaction between the concentration of Gandasil D fertilizer and growing media composition, namely at Gandasil D fertilizer concentration of 2 g/1 liter of water and a growing medium consisting of coco peat and compost with the parameters of plant height and stem diameter observed at 10 WAP. The Gandasil D fertilizer concentration of 2 g/1 liter of water affected the growth of Indigofera seedlings more effectively than other concentrations. A growing medium consisting of coco peat and compost with a ratio of 1:1 was more effective in boosting the growth of Indigofera seedlings than growing media consisting of other compositions.
