This practical thesis aims to reform the use of plant material in landscape architecture projects in the Najd or Central Region of Saudi Arabia. Many aspects of landscape architecture in Najd attempt to emulate western concepts. Neglect or unawareness of the values of Arabic society is one of the main reasons for the failure of the landscape programme. This factor of traditional culture is particularly sensitive in Najd which is the birthplace of Whabism, one of the strictest applications of Islam. This implies special conditions that made outdoor design sensitive and complicated, unable to tolerate western forms. Western urban patterns in planning, such as wide streets, neighbourhood parks and their detailed components of artifacts and plant materials, all shattered the character of traditional landscape architecture in the region. Although indigenous landscape elements in Najd evolved as a result of socio-environmental factors, many consultants do not differentiate between Persian, Islamic, and Najdi gardens. The inventory of available plant species indicates that most are imported from tropical and subtropical countries. These species require stripping of soil from wadi Hanifah for potting, and for top soiling planting projects, a process destructive to the rich wadi habitat. Such a process is necessary when using imported plant material while native ones can adapt to the existing sandy and saline soil. The devastation of the wadi ecosystem, the saline water table and the high cost of maintaining those plants, represents serious short and long term economic, ecological and technical implications. These implications all point to the scale of these negative consequences of using imported plant material. Also, climatic data, points to the suitability and adaptability of native flora and its significance in avoiding further damage to eco-environment. Use of imported plants in arid Najd and creating a man-made micro climate to suit them, is a waste of resources, especially the water budget in Saudi Arabia. The thesis proves that these plants consume large amounts of water, require high levels of maintenance, are unsuitable to Najdi environment, introduce new pests and diseases, require special microclimatic conditions, rich soil and prove unsuccessful in their functions. All the previous factors combine to acknowledge the failure of many tropical gardens in the arid land of Najd. The answer lies in Najd itself which is wealthy in flora adapted to its local conditions. The potential for their use in Saudi Arabian landscape projects is vast. Individually they will substitute for the imported nursury stock, while the available communities represent a ready-made and complete landscape element which would be valuable for Najdi parks. The general question, the comparative advantages of native over imported plants is conclusively answered in the thesis. Though the native plants are diverse, attractive and available, they were tested practically aiming at, firstly to test the individual species, the "target species method", and secondly to test the whole community "target community method". Three test sites were allocated in the Diplomatic Quarter to test the selected target species and communities. The tests were conducted extensively over five years and intensively over three years, during which the author monitored closely a large number of species and communities and arrived at an encouraging set of results and findings. The conclusion of the thesis consists of two parts. Firstly, the successful species which is included in a Flora, and the successful target communities which use selected target communities as a landscape design tool. These are aimed specifically at landscape designers. Secondly, the author recommends how to utilize both methods in a typical Najdi urban park, and how to encourage their successful use.

After mining, the chemical, physical and biological soil characteristics are unsuitable for replanting, making it difficult to environmental recovery. The aim of this study was to evaluate the use of green manure in organic and mineral fertilizer and their influence on the physical and chemical attributes of the area to be reclaimed and implementation of an agroforestry system. This work was developed in degraded area located at Barro Alto, Goias The study area has 5000 m2 and is in the process of recovery since February 2012. Two cycles of planting green manure the first in March 2012 were performed, and the second. In December 2012 the treatments were: 1- pigeonpea; 2- jack bean; 3- sunn hemp; 4- velvet bean; 5- milhet intercropping with faba bean; 6 - millet intercropped with beans pork; 7 - milhet intercropped with sunn hemp; 8- milhet intercropped with velvet bean and three nutrient sources: 1- fertilization with phosphate Arad; 2- the cattle manure; 3- mineral fertilizer controlled release fertilizers. Phytotechnical the characteristics of green manures (height, chlorophyll content, biomass production and nutrient accumulation ) , chemical properties (pH, macronutrients and soil organic matter) and physical soil (bulk density, macro and micropores, volume total pore, gravimetric moisture and penetration resistance ). An agroforestry system using three species, apeiba (pioneer), the baru (middle) and pequi (climaceaes) was implemented in February 2013. The results showed that 17.1% of the biomass originated in pearl millet indicating legumes are the main factors of increase in that variable. The use of mineral source (NPK) significantly increased the biomass of green manure, nutrient accumulation and plant height in relation to the Arad phosphate and manure. With the introduction of green manuring, the content of exchangeable soil Al, H + Al and Al saturation (m%) reduced by 55%, 18.46% and 37.47% in relation to beginning of recovery, respectively. The use of green manure increased the soil organic matter, base saturation and potassium in 156%, 41.71% and 52.41% in relation to beginning of recovery, respectively. The macro and microporosity, in addition to resistance to penetration, improved after 18 months of implementation of the recovery, demonstrating that cropping practices adopted for recovery of degraded in the study area is being active. After 270 days of planting of tree species cover crops and sources used did not influence the height and diameter. The apeiba excelled at increase in height and diameter than the baru and pequi. / A jazida de bauxita de Barro Alto, Goiás, é a primeira jazida de bauxita viável economicamente na região Centro-Oeste do Brasil e apresenta características peculiares. Após a lavra, as características químicas, físicas e biológicas do solo são inadequadas para a revegetação, o que dificulta a recuperação ambiental. Este trabalho teve como objetivo avaliar as alterações em atributos do solo durante a recuperação inicial de área de mineração de bauxita com utilização de adubos verdes, manejada com diferentes adubações e introdução de sistema agroflorestal. A área de estudo possui 5 mil m2 e está em processo de recuperação desde fevereiro de 2012. Foram realizados dois ciclos de plantio de adubo verde, o primeiro em março de 2012 e o segundo em dezembro de 2012. Os tratamentos foram: 1 - feijão guandu; 2 - feijão-de-porco; 3 - crotalária juncea; 4 - mucuna preta; 5 - milheto consorciado com feijão guandu; 6 - milheto consorciado com feijão-de-porco; 7 - milheto consorciado com crotalária; 8 - milheto consorciado com mucuna. E as três fontes de adubação foram: 1- adubação com fosfato de Arad; 2 - adubação com esterco bovino; 3 - adubação com fertilizante mineral de liberação controlada. Foram analisadas as características fitotécnicas dos adubos verdes (altura, teor de clorofila, produção de fitomassa e acúmulo de nutrientes), atributos químicos (pH, macronutrientes e matéria orgânica do solo) e físicos do solo (densidade do solo, macro e microporos, volume total de poros, umidade gravimétrica e resistência à penetração). Foi implementado em fevereiro de 2013 um sistema agroflorestal com utilização de três espécies, a apeiba (Apeiba tibourbou Aubl.) (pioneira), o baru (Dipteryx ala) (secundária) e o pequi (Caryocar brasiliense Cambess) (climáceaes). Os resultados obtidos demonstraram que 17,1% da fitomassa tiveram origem no milheto, indicando serem as leguminosas os principais fatores de incremento nessa variável. A utilização da fonte mineral (NPK) aumentou significativamente a fitomassa da adubação verde, acúmulo de nutrientes e altura das plantas em relação ao fosfato de Arad e ao esterco bovino. Com a introdução da adubação verde, o teor de Al trocável do solo, H+Al e da saturação por Al (m %) reduziram em 55%, 18,46% e 37,47% em relação ao início da recuperação, respectivamente. A utilização dos adubos verdes aumentou o teor de matéria orgânica, saturação de bases e potássio em 156%, 41,71% e 52,41% em relação ao início da recuperação, respectivamente. A macro e a microporosidade, além da resistência à penetração, melhoraram após 18 meses de implantação da recuperação, demonstrando que o manejo adotado para recuperação da área degradada no estudo está sendo atuante. Após 270 dias de plantio das espécies arbóreas, as plantas de cobertura e as fontes utilizadas não influenciaram a altura e o diâmetro. A apeiba se destacou no incremento de altura e diâmetro em relação ao baru e pequi.

Os parâmetros avaliados foram: massa verde; massa seca das plantas e determinação do teor de macronutrientes, micronutrientes e proteína bruta da massa seca das culturas de cobertura; quantidade de carbono; relação C/N; no feijoeiro, estande inicial; teor de clorofila das folhas; comprimento da raiz principal; componentes de produção: número de vagens por planta, número de sementes por vagem, número de sementes por planta, massa de 100 sementes, massa da palha, relação grão/palha, teor de nutrientes das sementes e produtividade; estande final; qualidade fisiológica de sementes: teste de germinação, primeira contagem, segunda contagem, matéria seca, índice de velocidade de germinação, comprimento da parte hipocótilo e raiz, teste de condutividade elétrica, teste de envelhecimento acelerado, teste de frio e teor de água dos grãos. Com base nos resultados, verificou-se que as plantas de cobertura Crotalaria juncea e Pennisetum glaucum proporcionaram maior volume de massa seca e elevado aporte de nutrientes para o cultivo de feijoeiro, em sistema de plantio direto. A inoculação das sementes de feijão com os estimulantes GeoRaiz Gram e Bacillus subtilis não proporcionaram ganho em produtividade do feijoeiro. As sementes produzidas apresentaram alta qualidade fisiológica, com excelente capacidade germinativa e alto vigor, indicando que os tratamentos favoreceram ao feijoeiro a condição de produção de sementes de alta qualidade. / Knowing the climatic conditions of the region, making the correct choice of cover crop species and the cultivation system, can improve the quality of the soil and favor the successor crop.

The evaluated parameters were: green mass; dry mass of plants and determination of the macronutrient, micronutrient and crude protein content of the dry mass of cover crops; amount of carbon; C/N ratio; in the bean plant, initial stand; chlorophyll content of leaves; length of the main root; production components: number of grain beans per plant, number of seeds per pods beans, number of seeds per plant, mass of 100 seeds, straw mass, grain/straw ratio, seed nutrient content and yield; final stand; physiological seed quality: germination test, first count, second count, dry matter, speed germination index, length of the hypocotyl and root part, electrical conductivity test, accelerated aging test, cold test and water content of the grains. Based on the results, it was verified that the cover plants Crotalaria juncea and Pennisetum glaucum provided higher volume of dry mass and high nutrient intake for bean cultivation, in no-tillage system. The inoculation of the common bean seeds with the GeoRaiz Gram and Bacillus subtilis stimulants did not provide gain in bean productivity. The seeds produced presented high physiological quality, with excellent germinative capacity and high vigor, indicating that the treatments favored the common bean to the condition of producing high quality seeds.

Visando melhorar depósitos do herbicida sobre as plantas é importante conhecer os fatores que possam interferir neste processo. Objetivou-se com a pesquisa avaliar em campo e em casa de vegetação a eficiência de volumes de aplicação reduzidos e concentrações glyphosate em função de condições agrometeorológicas distintas ao longo do dia na dessecação de Urochloa ruziziensis. Assim, realizou-se três experimentos. No primeiro foi avaliado em laboratório o espectro de gotas, tensão superficial de caldas e o ângulo de contato de gotas com três superfícies. O segundo experimento em ambiente controlado foi avaliado a influência de dois volumes de aplicação associado à cinco concentrações de glyphosate na calda em duas condições agrometeorológicas distintas no controle de U. ruziziensis. No terceiro foram avaliados dois volumes de aplicação e duas concentrações de glyphosate na calda em seis condições agrometeorológicas distintas e sua influência na densidade de gotas, cobertura por gotas, deposição da calda nas plantas e no solo e no controle da U. ruziziensis em condição de campo. As concentrações de glyphosate na calda influenciam nas características físico-químicas das caldas. E também em cada uma das duas condições agrometeorológicas nas condições semi-controladas, afetando no controle satisfatório de U. ruziziensis. O agrupamento dos componentes principais propicia maior compreensão das interações entre variáveis independentes com a eficiência da aplicação e eficácia de controle. A regressão em árvore de decisão (CRT) foi robusta para a avaliação da eficiência da aplicação em função das variáveis agrometeorológicas. / In the desiccation of vegetation cover, there may be insufficient or irregular deposition of sprayed herbicides. To improve herbicide deposits on plants it is important to know the factors that may interfere in this process. The objective of this research was to evaluate the efficiency of reduced application volumes and glyphosate concentrations in the field and in the greenhouse due to different agrometeorological conditions during the day in the desiccation of Urochloa ruziziensis. Thus, three experiments were performed. In the first one was evaluated in laboratory the spectrum of drops, surface tension of syrups and the angle of contact of drops with three surfaces. The second experiment in controlled environment was evaluated the influence of two application volumes associated with five concentrations of glyphosate in the syrup in two different agrometeorological conditions in the control of U. ruziziensis. In the third, two volumes of application and two concentrations of glyphosate in the syrup were evaluated in six different agrometeorological conditions and their influence on droplet density, droplet coverage, deposition of the syrup on the plants and on the soil and on the control of U. ruziziensis in condition of field. The concentrations of glyphosate in the syrup influence the physicochemical characteristics of the syrup. And in each of the two agrometeorological conditions under semi-controlled conditions, affecting in the satisfactory control of U. ruziziensis. The grouping of the main components provides a better understanding of the interactions between independent variables with application efficiency and control effectiveness. Decision Tree Regression (CRT) was robust for the evaluation of the efficiency of the application in function of the agrometeorological variables.
