Abstract:

Food security and eutrophication are two issues proven to have severe impacts on both humanity and the environment. This study suggests improving the local food security by utilizing phosphorus and nitrogen, available in severe eutrophic small lakes, in local food production, thus turning eutrophication from a problem into a resource. The study theoretically experiments the possibility of using eutrophic water in a greenhouse, where hydroponics is used as a cultivation method. The eutrophic water is pumped from the lake into the greenhouse, and then to the hydroponic system, which is expected

La torba è il materiale più utilizzato per i substrati impiegati nelle coltivazioni fuori suolo. Tuttavia, limitazioni relative ai costi e ad un possibile impatto ambientale dell’estrazione, nonchè alla disponibilità sul mercato da un anno all’altro, spingono la ricerca ad interessarsi a materiali alternativi. Sottoprodotti da produzioni/processi di trasformazione, possono rappresentare una fonte di materiali, con i vantaggi legati all’economia circolare.

Thesis (PhD)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: Soilless production of crops relies on the addition of high concentrations of nutrients with the irrigation water. The drained nutrient solution should be re-used to reduce the risk of pollution and to increase the water- and nutrient use efficiency of the system. Besides the risk of pathogen build-up, one of the main impediments of a wider application of this method is the frequent analysis required to maintain optimum nutrient concentrations and ratios in the rootzone. Yield reductions may be caused by an unbalanced nutri

Abstract:

Freshwater is a finite resource that is rapidly becoming more scrutinized in agricultural consumption. Specialty crop producers, especially ornamental crop producers, must continually improve production sustainability, with regards to water resource management, in order to continue to stay economically viable. Soilless substrates were initially developed to have increased porosity and relatively low water holding capacity to ensure container crops would not remain overhydrated after irrigations or rain events. As a result, substrates were selected that are now considered to be in efficient in

Abstract:

Growing landscape trees in containers is a common practice in the nursery industry. In the southeastern United States, pine bark is often used as a container substrate, and two common amendments to pine bark are lime and micronutrients. In this study, three experiments were conducted to determine the effect of these amendments on the growth of a wide range of landscape tree species grown in pine bark. In the first experiment, nine species of landscape trees [Acer palmatum (Japanese maple), Acer saccharum (sugar maple), Cercis canadensis (redbud), Cornus florida (flowering dogwood), Cornus k

One of the motivating reasons for the development of hydroponics was avoidance of root pathogens. Hydroponics involves growing crops in relatively sterile media, isolated from the underlying soil which may have disease pressure. However, even when hydroponics is coupled with controlled environments such as high tunnels and climate-controlled greenhouses, soil-borne pathogens can enter the growing area and proliferate due to optimal environmental conditions for pathogen growth. Control of root pathogens is difficult and usually achieved through synthetic fungicides since few biocontrol options

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The potato plant is highly demanding regarding the presence of phosphorus (P) readily available in soil solution. To achieve high yields of tubers, large applications of phosphate fertilizers are made, which consequently reduce the sustainability of the potato chain and cause possible environmental contamination. Therefore, it is necessary to improve the management of fertilizer use and develop potato clones that have high yield and quality, even in limiting conditions of P. In order to identify efficient clones in P acquisition an

Abstract:

A doença vassoura-de-bruxa reduziu expressivamente a produtividade dos cacauais da região sul da Bahia, maior produtora nacional. O controle genético da enfermidade, com o uso de plantas tolerantes e com alto potencial produtivo, tem sido a principal estratégia para o convívio com essa doença. O plantio de mudas clonais, provenientes de estacas enraizadas, tem mostrado ser uma prática promissora para a renovação da lavoura. O Instituto Biofábrica de Cacau (IBC), criado em 1999, tem como um de seus objetivos produzir e comercializar essas mudas. Estudos preliminares mostraram a necessidade de a

The objectives of this work were to test different salt and sucrose concentrations in the in vitro medium and acclimatizing systems for production of strawberry stock plants. One experiment was conducted at the Breeding and Plant Propagation Laboratory and two experiments inside a screen house at the Department of Fitotecnia UFSM, from February to October, 2008. In the first experiment, sucrose 15; 30; 45 and 60g/L and salt ½; ¾ and 1 MS concentrations were compared, in a 3x4 factorial randomized experimental design, with five replications of five plantlets.

Abstract:

The yield of common bean crop is affected by high air temperature during the reproductive phase. The experiment was carried out in pots and in growth chambers (phytotron) with controlled air temperature and humidity. The objective of this study was to identify the most appropriate substrate for common bean grown in pots and to evaluate common bean genetic variability for tolerance to high air temperature during the pre-flowering (R5) to pod formation (R7) phase. To identify the most appropriate substrate two experiments were carried out in a greenhouse during 2005, with the TPS Nobre common be

The objectives of this research were to select new strawberry clones for the estate of Rio Grande do Sul, Brazil, and to develop methods of multiplication to obtain disease-free transplants with high physiological quality. Five advanced strawberry clones from the Breeding Program and two controls were evaluated in an annual hill system in low tunnels from April to December, 2006. A closed soilless system was developed, based on a growing bed with substrate over a cement tile. A nutrient solution was delivered from a reservoir to the upper end of the tile and drained off back by gravity. An ine

Resumo: Devido a mudanças no hábito alimentar o consumo de alface vem aumentando, sendo seu fornecimento diário, o ano todo. Sendo assim, o cultivo hidropônico tem sido adotado por muitos produtores. Apesar disso, muitas cultivares ainda não são adaptadas a essa tecnologia. O objetivo deste trabalho foi avaliar o desempenho de cinco cultivares de alface em dois ambientes de cultivo no sistema hidropônico, tipo NFT, no período de 06/02 a 07/04 de 2006 em Ribeirão Preto, estado de São Paulo, Brasil.

Abstract:

The many medicinal, nutritional, industrial, and agricultural uses of moringa are well documented, although studies remain focused on moringa as a wild, uncultivated plant and little horticultural research has been devoted to its culture. Greenhouse experiments were conducted at the State University of New York at Cobleskill, New York, USA during the summer of 2006. Soilless culture has been investigated as an alternative production system for medicinal and aromatic plants, and moringa seedlings were grown using hydroponic and aeroponic culture at a pH of 5.5-6.0 and electrical conductivity le
