DOWNLOAD EBOOK →Most conventional gardening books concentrate on how and when to carry out horticultural tasks such as pruning, seed sowing and taking cuttings. This book is unique in explaining in straightforward terms some of the science that underlies these practices. It is principally a book of 'Why' - Why are plants green? Why should one cut beneath a leaf node when taking cuttings? Why do plants need so much water? But it also goes on to deal with the 'How', providing rationale behind the practical advice. The coverage is wide-ranging and comprehensive and includes the basic structure and functioning of garden plants, nomenclature, genetics and plant breeding, environmental factors affecting growth, methods of propagation and production, pest and disease control, and post harvest management and storage. Published on behalf of the Royal Horticultural Society, this book will be a most valuable text for those sitting the RHS general examination, and horticultural students at certificate and diploma levels; it will also appeal to gardeners, growers and scientists.

DOWNLOAD EBOOK →First published in 1966, Lockhart and Wiseman’s Crop Husbandry Including Grassland has established itself as the standard crop husbandry text for students and practitioners alike. Radically revised and expanded, and with a new team of authors, the eighth edition confirms and extends its reputation.Part one looks at the basic conditions for crop growth with chapters on plant structure and growth, soil analysis and management, and the use of fertilisers and manures. There is also a new chapter on the influence of climate and weather. Part two surveys general aspects of crop husbandry. As well as a discussion of cropping techniques, there are new chapters on the important new areas of integrated crop management and organic crop husbandry, as well as discussion of seed selection and production. Part three then looks at how these general techniques are applied to particular crops, with chapters on cereals, root crops, fresh harvested crops, forage crops and combinable break crops. Part four considers the use of grassland with chapters on classification, sowing and management, grazing and conservation for winter feed.Lockhart and Wiseman’s Crop Husbandry Including Grassland remains the standard text for general agriculture, land management and agri-business courses, and is a valuable practical reference for the farming industry. The eighth edition has been widely expanded and remains the standard text for general agriculture, land management and agri-business courses Includes new chapters on cropping techniques, integrated crop management and quality assurance, seed production and selection and the influence of climate Discusses basic conditions for crop growth, how techniques are applied to particular crops, the influence of weather and the use of grassland

Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.
