Article: Improving Quality of Crocus Sativus Through the Use of Bacillus Subtilis

Abstract
In this study the ability of B.subtilis to improve the quality of C.sativus cultivation was evaluated. Various scientific studies demonstrate the medicinal properties of its constituents, making it one of the most expensive agricultural products in the world. The presence of microorganisms in the soil promotes the growth of plants, thanks to this capacity, today there are several microbial products marketed that can increase the health and growth of plants. Several scientific researches have demonstrated the beneficial effects of rhizosphere bacteria on roots and overall plant growth. In this study the ability of B.subtilis to improve the quality of C.sativus cultivation was evaluated. The two experimental groups in cultivation were: i) group without beneficial micro-organisms, irrigated with water and substrate previously fertilized; ii) group with beneficial micro-organism B.subtilis, irrigated with water and substrate previously fertilized. Growth-promoting bacteria and in particular Bacillus subtilis have important effects on plant morphology even under stressful conditions. In this experiment it is noted above all that the substrates enriched with B.subtilis for the cultivation of Crocus sativus led to a significant increase in all the agronomic parameters analyzed (length and leaves number, vegetative and root biomass, bulb weight, flowers number and stigmas length). This confirms how the use of B.subtilis can improve the solubility and availability of nutrients that improve plant growth accordingly.
