Pertumbuhan Vegetatif dan Reproduktif Tanaman Padi dan Jagung pada Berbagai Dosis dan Waktu Aplikasi Pupuk Hayati

Abstract

The objectives of this research was to find the best dosages and application time of biofertillizer in improving rice (Oryza sativa) and maize (Zea mays) growth and production. This research consisted of two experiments, i.e. dosages and application time experiment. Each experiment was carried out in the green house by Completely Randomize Design with three replications. The dosages experiment consisted of 4 treatments, P0 without biofertillizer, P1-P3 with biofertillizer of 50 g, 100 g, and 150 g per polybag. All the media were prepared using a mixed soil and compost ((5:1) v/v) and anorganic fertillizer of NPK (15:15:15) 8,75 g per polybag. Application time experiment consisted of 3 treatments, H0: 0 day after planting, H1: 4 days after planting, and H2: 14 days after planting. The biofertillizer with the dosages of 150 g per polybag showed the best result indicated by growth and yield parameters. The best time of application was 14 days after planting which indicated by the higher growth parameters and seed yield of rice and maize.
