Canola production in Western Australia is vulnerable to large variations in rainfall and frequent droughts. Recent poor seasons and price volatility have contributed to farmers' perceptions of risk with canola and it can be observed that the area of canola grown often declines after periods of drought. Nevertheless, the total area of canola grown in Western Australia has still increased over the last five years and the importance of the crop has become even more apparent. An increase in the area of potassium deficient agricultural sandy soils and the prediction of drier years in the Western Australian wheat belt has been identified. Therefore, more work is needed to enhance the current knowledge on plant physiological responses to potassium deprivation and drought stress particularly for canola.The first objective was to measure drought tolerance of canola under different potassium treatments. The second objective was to understand the mechanisms controlling drought tolerance of canola by comparing the response of varying potassium treatments during a drying cycle as well as monitoring the ability to recover after the drought stress. The third objective was to observe any morphological differences of canola plants exposed to different potassium levels and water stress. In order to achieve these objectives, a range of climate chamber, glasshouse and field experiments were conducted growing Trigold canola plants in sandy soils and hydroponically, mixed with increasing potassium concentrations, which were subjected to drought stress.This project increased our understanding of the effect of potassium nutrition on the drought response of canola. A mild potassium deficiency (40 mg kg-1 soil potassium) only decreases the dry weight of canola significantly if plants are exposed to a long-term potassium deprivation. The ability to maintain a similar size over a range of applied potassium levels could be due to a morphological mechanism that might have evolved in canola to manipulate root growth towards a smaller shoot:root ratio. The low K treatments had increased transpiration and stomatal conductance and reduced relative turgor pressure compared with high K, under drought stress. This was due to the stomata remaining open in the low k and closed in the high K. Canola with a higher supply of potassium also had a higher rate of photosynthesis under water stress than canola with a low level of applied potassium. The opening of the stomata and associated higher transpiration rate and stomatal conductance may be caused by an interaction effect of the plant hormones abscisic acid and ethylene depending on the level of potassium and water stress that the canola plant is exposed to.Thus, further work should focus on measuring abscisic acid and ethylene levels under varying water and potassium treatments in order to understand the mechanisms behind this response and how best to mitigate the effects of the stress. In addition to that, research should be done on the interaction between potassium and drought by studying the canola plants grown continually at different soil moisture and potassium levels in particular focusing on the 40-60 mg kg-1 soil potassium level where most changes have been observed in order to determine any effects on plant size, shoot:root ratio, relative turgor pressure and transpiration per leaf area. Especially to monitor any changes in shoot:root ratio, which may be a useful morphological trait for selection of drought tolerance in canola. The interaction between nitrogen and potassium on canola response to drought also needs further investigation because it may be necessary to apply higher amounts of potassium fertiliser when applying relatively high nitrogen rates.

[Truncated abstract] Canola (Brassica napus) is the major oilseed crop in Western Australia. The areas sown to canola vary between 600,000 and 700,000 hectares per season, with the potential for an increase by up to half a million hectares per season, with the seed production of up to million tonnes per year. Canola production in Western Australia is constrained by poor soil fertility. In Western Australia, soils are among the most ancient and therefore heavily leached in the world, and have low availability of P, N and S. Identification and breeding of genotypes that could use soil N and S as well as fertilizer N and S more efficiently than standard genotypes would be a sustainable long-term approach to dealing with (i) high N and S requirements in canola, and (ii) low N and S availability in Western Australian soils. In the study presented here, modern Australian canola germplasm was screened for N and S efficiency during the vegetative stage. Group of genotypes either with high or low N or S efficiency in the preliminary study were then screened for N or S efficiency at maturity. The mechanisms involved in transport and remobilization of N- or S- containing compounds were investigated via analyses of the xylem and phloem analyses following soil and leaf labeling with stable isotopes 15N and 34S. Nitrogen and S efficiency in Australian canola germplasm was successfully differentiated in the vegetative growth stage in 84 canola genotypes. Nitrogen and S efficiency ranking among six N- or S-efficient and six N- and S-inefficient from preliminary screening study was verified in the additional experiment during the vegetative stage. Canola genotypes differed significantly in N efficiency at grain maturity. Genotypes Wesway and 46C74 that were ranked as efficient in the vegetative stage remained efficient at maturity, whereas genotype Surpass 603 CL was ranked inefficient during the vegetative stage and efficient at maturity. Canola genotypes significantly differed in S efficiency at maturity. However, there was no correspondence between efficiency ranking in the vegetative stage and the maturity...

This book gives a complete picture of the canola crop including its history, botany, genetics, distribution, breeding and biotechnology, production, processing, composition, nutritional properties and utilization of the seed, oil and meal, as well as an economic profile. While the main focus in this book is on canola of Canadian origin, its cousin crop oilseed rape will also be discussed to a lesser extent. The work provides up-to-date information on the crop and highlights areas where research and development is either needed or is in process. Provides extensive information on the canola plant, including breeding, genetic engineering for trait development, and seed morphology and composition Editors and contributors are global leaders in canola research and application Offers a comprehensive overview of canola oil and meal composition, nutrition, and utilization

This is the updated 6th edition of Growing Vegetables West of the Cascades, which has evolved from a self-published pamphlet to the master guide to organic vegetable gardening over the past 28 years. Steve Solomon, who was a founder of the Territorial Seed Company, was one of the early proponents of organic gardening, and the first to codify and refine the best practices of small-plot vegetable gardening in the Pacific Northwest. The approaches to understanding and preparing soils, composting, chemical-free fertilizers, efficient uses of water, and garden planning are universal to any climate or region. Solomon gets specific in his extensive advice on growing specific crops in the gentle maritime Northwest climate. This update includes his latest findings on seed sources, refinements in growing and cultivation techniques, and other organic gardening best practices. Growing Vegetables West of the Cascades lays out the principles, but the author advocates that readers think for themselves and grow their gardens as they see fit.
