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 and germination and other reproductive aspects. 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. It has been reported that biostimulants reinforce plant vigor making them more resilient to survive and recover during various environmental stress. Their use to promote plant growth, yield and to overcome stress tolerance in a sustainable manner has increasingly gained attention. Although biostimulants have successfully been used for promoting the growth and development of many species, their role in promoting sexual and vegetative reproductive growth and development of marketable crops has not been widely investigated. This book focuses on a sustainable approach in utilization of these promising biostimulants in agriculture, horticulture and floriculture for better productivity and to feed a growing world population.
