Download or read book Crop Protection in Medieval Agriculture written by Jan C. Zadoks and published by Sidestone Press. This book was released on 2013-10-16 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed a rapid rise in engagement with emotion and affect across a broad range of disciplines in the humanities and social sciences, with geographers among others making a significant contribution by examining the emotional intersections between people and places. Building on the achievements of Emotional Geographies (2005), the editors have brought together leading scholars such as Nigel Thrift, Alphonso Lingis and Frances Dyson as well as young, up and coming academics from a diverse range of disciplines to investigate feelings and affect in various spatial and social contexts, environments and landscapes. The book is divided into five sections covering the themes of remembering, understanding, mourning, belonging, and enchanting.

Download or read book Pollination Mechanisms Reproduction and Plant Breeding written by R. Frankel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility.
