Biostimulants for Improving Reproductive Growth and Crop Yield highlights their importance as a mechanism, specifically for this result. Intended to transform the latest scientific research into practical application, the book focuses on the effects of biostimulants on flower and fruit development and set, early flowering, pollen viability, germination, and other reproductive aspects. It covers a sustainable approach in utilization of these promising biostimulants in agriculture, horticulture, and floriculture for better productivity, and to feed a growing world population. Biostimulants are a group of substances of natural origin and/or microorganisms that offers the potential to reduce the dependency on harmful chemical fertilizers that cause environmental degradation. The application of biostimulants represents one of the most innovative and promising strategies to improve crop productivity.
