This book was released on 2019 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid set canopy delivery system (SSCDS) are envisioned as viable alternatives to conventional spraying techniques like an axial-fan airblast sprayer in tree-fruit orchards and vineyards. While SSCDS may reduce the amount of spray drift, exposure to pesticides, carbon footprint and drive-row compaction, it needs field scale optimization in terms of emitter selection, placement and scalability. Therefore, the overall goal of this research was to customize SSCDS in model perennial specialty crops grown in the state of Washington.Different SSCDS configurations were developed using off-the-shelf emitters for a high-density tall spindle trained apple orchard and a modified vertical shoot position trained vineyard. Suitable emitter types and their within canopy placement were identified through analyzing spray performance at different canopy locations. Field spray trials indicated the requirement of emitters at multiple canopy locations for adequate spray deposition and coverage. Moreover, hollow-cone emitters facilitated spray penetration into the foliage. The optimized SSCDS provided comparable spray deposition to that of an airblast sprayer in grapevines with significantly reduced off-target drift.A pneumatic spray delivery (PSD) system was developed to address the issue of non-uniform spray application pertinent to conventional hydraulic spray delivery (HSD) based SSCDS. A reservoir sub-system was developed and integrated with the HSD to have precisely metered spray material at each of the spray locations. While the drop in operating pressure was similar in both the systems, the PSD system had uniform spray output throughout the spray row length. Such design resulted in consistently higher spray deposition and coverage at different canopy locations in a high-density apple orchard.A rapid estimation method of tree-row-volume (TRV), leaf-wall-area (LWA), canopy volume (CV) and canopy cover (CC) was developed based on unmanned aerial system (UAS) acquired aerial imagery data. Precise estimation of TRV and LWA (R2 > 0.75) was achieved. Moreover, CV and CC estimates were significantly correlated to the ground measurements (p

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Download or read book Old Southern Apples written by Creighton Lee Calhoun and published by Chelsea Green Publishing. This book was released on 2011-01-20 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book that became an instant classic when it first appeared in 1995, Old Southern Apples is an indispensable reference for fruit lovers everywhere, especially those who live in the southern United States. Out of print for several years, this newly revised and expanded edition now features descriptions of some 1,800 apple varieties that either originated in the South or were widely grown there before 1928. Author Lee Calhoun was one of the foremost figures in apple conservation in America. This masterwork reflects his knowledge and personal experience over more than thirty years, as he sought out and grew hundreds of classic apples, including both legendary varieties (like Nickajack and Magnum Bonum) and little-known ones (like Buff and Cullasaga). Representing our common orchard heritage, many of these apples are today at risk of disappearing from our national table. Illustrated with more than 120 color images of classic apples from the National Agricultural Library’s collection of watercolor paintings, Old Southern Apples is a fascinating and beautiful reference and gift book. In addition to A-to-Z descriptions of apple varieties, both extant and extinct, Calhoun provides a brief history of apple culture in the South, and includes practical information on growing apples and on their traditional uses.

Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.
