Plant growth promoting rhizobacteria (PGPR) are soil-dwelling microorganisms that live in association with plant roots. PGPR can play an important role in agricultural by enhancing crop production as well as increasing plant resistance against damaging pests and diseases. In the case of the destructive viral disease of cereal crops barley yellow dwarf virus (BYDV), there is currently no treatment available after a plant becomes infected. Control of this aphid-transmitted viral disease is limited to resistant plant cultivars and/or chemical control of vector populations. With increasing environmental pressures to move towards sustainable agriculture, PGPR-based disease control provides a viable alternative to chemical pesticide applications. Here, we aimed to review the potential use of PGPR Azospirillum brasilense to protect wheat plants against barley yellow dwarf virus, and the underlying mechanisms for PGPR-mediated changes on plant-virus-vector interactions.

The proxy of GCG in this study is institutional ownership and the frequency of board meetings while the debt policy is proxied through leverage (debt equity ratio). The population in this study is that all companies indexed by compass 100 listed on the Indonesia Stock Exchange in 2016-2017 are 66 companies, with the sampling method using purposive sampling. The results obtained in this study are that institutional ownership has no influence on dividend policy either directly or indirectly through variable intervening ROE. While the frequency of board of directors meetings and debt policy (DER) has an influence on dividend policy both directly and indirectly through variable intervening ROE. The conclusion of the study is that profitability is able to become a variable intervening between GCG proxied through the frequency of board of directors meetings and debt policies that are proxied through DER on dividend policy.
