Paperback. Etat : New. Print on Demand. This book presents pioneering experimental research on tobacco growth carried out by the Canadian government in 1908. The author provides observations and practical conclusions, gained over one season, on growing seed plants, soil sterilization, and using chemical fertilizers. They investigate the optimal time for harvesting mature seeds and consider the importance of seed selection and the number of leaves retained by the plant during this process. The authors identified the mosaic disease as a threat, describing its symptoms and their theories on its origin. Through comparing various soil treatments, the text explores the benefits and effectiveness of formalin and steam sterilization methods for controlling this disease. They detail their choice of chemical fertilizers, providing readers with valuable insights on nitrogen, phosphoric acid, and potash content. The book concludes with a discussion on the positive impact of commercial fertilizers and barn-yard manure in tobacco culture and emphasizes the importance of preserving soil fertility. These findings contribute to the wider body of knowledge surrounding tobacco cultivation and provide practical advice to support farmers in their crop management practices. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
