The application of microorganisms of phosphate providers and organic matters to improve the growth of Arabica coffee seedlings at Andisol in Bener Meriah Regency

Abstract

Purpose

The purpose of this paper is to examine the effect of the application of microorganisms of phosphate providers and organic matters for the growth of Arabica coffee seedlings in Bener Meriah Regency.

Design/methodology/approach

The experiments were performed inside the screen house using a random design of factorial group with six repetitions. The experimental treatments consisted of two factors. Factor I is the application of microorganisms of phosphate providers. Factor II is the application of organic matters (T. diversifolia and the coffee bean skins). The parameters observed were as follows: enhancement of plant height was observed every 30 days for 270 days, and a number of primary branch and dry weight of roots were observed 270 days after planting (DAP). The data obtained were analyzed by analyzing the variance at 5 per cent level; if the treatment had an effect, then the treatment was continued to Duncan’s multiple range test at 5 per cent.

Findings

The application of microorganisms of phosphate provider increases the height improvement, the number of primary branches and the dry weight of roots of Arabica coffee seedlings. The application of Listeria sp. microorganisms of phosphate provider gives the highest yield on the height increase, the number of primary branches and the dry weight of roots of Arabica coffee seedlings. The application of organic matters of coffee beans skin gives higher yield than Tithonia diversifolia in height and dry weight of roots of Arabica coffee seedlings. The interaction between the application of microorganisms of phosphate provider and organic matters increases the dry weight of roots of Arabica coffee seedlings. The interaction of Listeria sp.-skin of coffee beans gives the highest yield on dry weight of roots of Arabica coffee seedlings.

Originality/value

Several other studies have demonstrated that the application of microorganisms of phosphate providers using phosphate solubilizing bacteria (Fitriatin et al., 2014; Sembiring et al., 2017) and mycorrhizal use (Hart and Trevors, 2005; Rouphael et al., 2015) increased the growth and yield plant. No previous study comprehensively studied the application of microorganisms of phosphate providers and organic matters to improve the growth of Arabica coffee seedlings in Andisol in Bener Meriah Regency.
