Efektivitas Mikroba Probiotik dalam Formulasi Pasta dan Cair terhadap Mutu Benih dan Pertumbuhan Jagung Hibrida

Abstract

The improvement of soil quality and agricultural increase using probiotic microbes have been proven in a variety of commodities including maize. The study was conducted to obtain the best formulation of microbial probiotic that is able to maintain seed quality and support the growth of hybrid maize (F1). The research was conducted at the Seed Science and Technology Laboratory, Bogor Agricultural University and continued in the experimental garden of Cikarawang, Kec. Dramaga, Kab. Bogor in March-December 2016. The two formulations of paste and liquid also six combinations of probiotic microbes were tested for viability and the seeds vigor using CRD two factor three replications. The experiment was continued by testing it effects toward plant growth with a split split plot design on three replications. The treatment factors were augmented with the use of NP fertilizer in 0%, 25%, 50%, 75% and 100% doses from the recommended doses. The six combinations of probiotic microbes used include: I1 (P24-AzL7), I2 (P24-AzL9), I3 (B28-AcCKB4), I4 (P24-AcCKB9), I5 (P24-AcCKB20), and I6 (P24-AcCKW5). The result shows that the paste formulation is more effective against the speed and synchronization of germination, while the liquid formulation is more effective against seed viability. The suitability of microbial probiotic formulation is influenced by microbial type and nutrient availability of plants. The formulations are not toxic for microbes and safe for seeds, so they are potentially further developed.
