1. Horticulture in prehistoric New Zealand : an investigation of the function of the stone walls of Palliser Bay - Leach, Helen M
Low stone rows and alignments were reported as early as 1904 on the coastal platform of eastern Palliser Bay. In all subsequent references it was assumed that the features were horticultural and, on the grounds of their appearance, of considereable age. Methodical investigation of these claims within the context of a three year archaeological programme (1969-1972) including analysis of prehistoric settlements, economy, and physical anthropology, was regarded as a worthwhile project, since orthodox opinion at the time favoured a later introduction of Polynesian horticulture some centuries after initial settlement of New Zealand about the 9th century AD. Extensive field surveys showed...

2. Horticulture by irrigation. - Gipson, A. E.
138 p.

3. A Model of New Industry Development in Horticulture - Collins, Raymond. J.
An important premise of new crops research in horticulture is that biologically successful new species can lead to successful new industries. Success in a biological sense is a necessary but insufficient condition because successful new crop industries are driven by economic and social factors as well as biological factors, and in practice these three sets of factors interact as a system. How to model any one of the biological, economic or social sub-systems is reasonably well understood, but modelling the dynamics of the whole system is more problematic. This paper presents a descriptive model that may be a first step...

4. Principles of plant culture; an elementary treatise designed as a text-book for beginners in agriculture and horticulture. - Goff, E. S. (Emmett Stull), 1852-1902
276 p.

5. Impact of horticultural mineral oil and synthetic pesticides on arboreal and soil fauna biodiversity within citrus orchard ecosystems - Liang, Weiguang; University of Western Sydney; College of Science, Technology and Environment; School of Science, Food and Horticulture
The results of the 3-year project successfully indicated that petroleum-derived spray oils can be used for effective control of a range of citrus pests including citrus leafminer, Asiatic citrus psyllid, chaff scale, red scale, citrus red mite. The results suggested that it should be possible, through use of horticultural and agricultural mineral oils and enhanced natural enemy activity, to reduce the number of pesticide sprays applied annually in China from 14-16 sprays to significantly fewer sprays in most regions. The results are also valuable as references for the implementation of citrus integrated pest management programs in Australia and other citrus-growing...

6. Impacto de la devaluación de principios de 2002 en el Cinturón Hortícola Platense: Estrategias tecnológicas adoptadas, sus resultados y consecuencias - García,Matías; Hang,Guillermo M.
La horticultura platense se caracteriza por su sistema de producción bajo invernáculo, altamente dependiente de insumos que en su mayoría son importados y dolarizados. Paralelamente, el producto hortícola fresco obtenido es no transable, debiéndose comercializar en el mercado interno. Debido a esto, la devaluación de principios de 2002 inauguró una etapa crítica para el sector hortícola en general y el platense en particular. Ante este contexto se investigaron las diferentes estrategias adoptadas por los productores y el impacto resultante a nivel mercado, precios y costos, como así también los resultados físicos y económicos de los establecimientos hortícolas. Para ello se...

10. Brigham Young University Department of Agronomy and Horticulture Historical Files - Brigham Young University. Dept. of Agronomy and Horticulture
The Department of Agronomy and Horticulture is part of the College of Biology and Agriculture. It was created in 1967 when the Department of Agronomy and the Department of Horticulture were merged to strengthen both programs. The new department was part of the College of Biological and Agricultural Science that had been created in 1954. Prior to that, both departments had been members of the College of Applied Sciences. An important part of the Department of Agronomy and Horticulture is the University farm located in Spanish Fork, Utah. This collection is divided into two series: I. Department History Files, 1937-88...

11. Empirical series of journal h-indices: the JCR category Horticulture as a case study - Liu, Yuxian; RAO, Ravichandra; ROUSSEAU, Ronald
Two types of series of h-indices for journals published in the field of Horticulture during the period 1998-2007 are calculated. Type I h-indices are based on yearly data, while type II h-indices use cumulative data. These h-indices are also considered in a form normalised with respect to the number of published articles. It is observed that type I h-indices, normalised or not, decrease linearly over a period of ten years. The type II series, however, is not linear in nature: it exhibits partly a concave shape. This proves that the journals (in Horticulture) do not exhibit a linear increase in h-index...

14. Comparative analysis of the EFuNN and the Support Vector Machinemodels for the classification of horticulture data - Brendon J. Woodford
Support Vector Machines (SVM) over the past six years have emerged as one of the more robust classification architectures coupled with good generalisation capabilities. Similarly the Evolving Fuzzy Neural Network (EFuNN) have also been reported to posses these properties as well. This paper compares these two models and then applies them to the classification of two datasets taken from the horticulture industry. The results that are reported indicate that the EFuNN performs comparably well against its statistically based counterpart.

19. Lunar horticulture. - Walkinshaw, C. H.
Discussion of the role that lunar horticulture may fulfill in helping establish the life support system of an earth-independent lunar colony. Such a system is expected to be a hybrid between systems which depend on lunar horticulture and those which depend upon the chemical reclamation of metabolic waste and its resynthesis into nutrients and water. The feasibility of this approach has been established at several laboratories. Plants grow well under reduced pressures and with oxygen concentrations of less than 1% of the total pressure. The carbon dioxide collected from the lunar base personnel should provide sufficient gas pressure (approx. 100...
