Pertumbuhan dan produksi nanas (Ananas comosus (L.) Merr.) varietas MD2 dengan pemberian pupuk hayati dan organo mineral di Pina Plantation, Subang

Abstract

Pineapple [Ananas comosus (l.) Merr.] is one of the tropical fruit commodity that much developed in Indonesia, one of them is MD2 variety. Inorganic fertilizer is widely used to increase productivity in pineapple cultivation, but application of inorganic fertilizer that excessive caused soil damage. Biofertilizer application that can increase organic matter decomposition, increase nutrition availability for pineapple. This study aims to know the influence of the Provibio Biofertilizer and Organo Mineral on vegetative growth and production yield of pineapple at PT Pina Plantation, Subang, West Java. This experiment twelve months old MD2 Pineapple variety was used as indicator plant. This experiment used single factor randomized block design with five levels of treatment. The treatment consisted of P0 (control), P1 (100% Urea and KCl), P2 (100% Provibio Biofertilizer), P3 (50% Urea and KCl + Provibio Biofertilizer) and P4 (50% Urea and KCl + Provibio Biofertilizer + Organo Mineral). Each treatment was replicated three times, thus resulted 15 experimental units. The treatment was carried out on the MD2 variety pineapple aged 12 months after planting (BST). Fertilizing each treatment is once a month for four months of research. Pineapple production is carried out at harvest time entering 24 BST. The results showed that vegetative growth in leaf width of P4 treatment (50% Urea and KCl + Provibio and Organo Mineral Biofertilizers) produce the largest leaf width which very influential on pineapple production with the largest yield in the same treatment is (P4) the compared (P0) and (P1). Thus, the provision of biofertilizer for Provibio and Organo Minerals can be to increase pineapple production and reduce 50% of the use of urea and KCl fertilizers.
