Cultivo de pimiento en invernadero. Influencia de la humedad ambiental y de la salinidad - Muñoz Odina, Pere; Antón Vallejo, Ma. Asunción; Montero Camacho, Juan Ignacio
El cultivo de pimiento se caracteriza por presentar una alta susceptibilidad a la necrosis apical (Blossom-end-rot, BER). El BER es una fisiopatía originada por una deficiencia de calcio durante el estado inicial de desarrollo del fruto. Los altos valores de radiación y déficit de presión de vapor (DPV) característicos de la zona mediterránea afectan considerablemente a la transpiración y a la absorción de minerales favoreciendo la aparición de BER.
En el Institut de Recerca i Tecnologia Agroalimentàries (IRTA) se han realizado dos experiencias en cultivo sin suelo de pimiento con el objetivo de evaluar el efecto de la humedad ambiental y...

Plant genotype, juvenility and mechanisms of inhibition of rooting Persoonia virgata R. Br. cuttings - Bauer, L. M.; Johnston, M. E.; Williams, R. R.
Persoonia virgata is an endemic shrub of Australia that is being bush-harvested for its foliage and sold on the domestic and export flower markets. The limiting factor to the cultivation of many desirable Persoonia species has been the extreme difficulty in developing a reliable propagation system. This study investigated the effects of cutting type, maturity of the stock plant, and genotype, on the rooting of P. vilgata cuttings. It was found that juvenile cuttings rooted significantly better than mature cuttings. Some juvenile seedling genotypes yielded no rooted cuttings, whereas others produced up to 90% rooting. No anatomical barrier to root...

Building supply networks: how growers gain their marketing edge - Brown, Les; Cruikshank, Margaret; Johnston, D.
[Abstract]: This paper reports on research conducted by the authors in conjunction with the Commonwealth Department of Food, Fisheries and Agriculture on developing a strategic approach to training Australia’s horticultural groups. The need for training has arisen because many horticulturalists lack the resources (time, funds, etc) to address broad marketing and managerial issues as well as physically run farms. As post harvest expenses already can be up 70% of farm costs, and as growers are under increasing cost-pressures such as developing product integrity systems in order to maintain their right to supply, the need for training to cope with such...

What future the cane industry: is training a vehicle for change? - Brown, Les; Cruikshank, Margaret; Johnston, D.
[Abstract]: This paper summarised research into the training needs of cane growers in Queensland and Northern New South Wales for the Sugar Research and Development Corporation (SRDC). The full report supplied comprehensive insights into industry training needs from the perspective of those most directly involved in the production side. As a result of historically low price returns and in some areas, lingering effects of lower than average rainfall, many cane growers are faced with difficult prospects: exiting the industry, seeking to augment incomes by off-farm employment, or diversifying their farming operations. Prior research has shown that farmers undertaking training in...
