Growth and production of japanese taro (Colocasia esculenta var. antiquorum) by using plastic mulch and biofertilizer

Abstract Japanese taro (Colocasia esculenta var. antiquorum) production in Indonesia is around 20 tons/hectare, but it still relatively low due to the level of farmer management including fertilizing and watering especially dry season. We determined effect plastic mulch biofertilizer on growth japanese plants. This research used a split plot design. The main was consist two levels, namely control mulch, while sub-plots were biofertilizer, which levels: biofertilizer; with four replications. Each planted 22 Parameters observed plant height, leaf number, width, fresh top weight, tuber yield, number tubers. r esults are treatment had an height largest average found 55.98 cm, width 25.09 weight 197.03 g, plants 22.50 g. affected significantly width. Mulch affects highest 881.50g/plant equal t/ha, tubers 32 bulbs. However, not significant conclude that can increase growth, yield tubers, better than combination its
