AbstractCanadian Western Hard Red Spring (CWRS) wheat is recognized as premium quality wheat, ideal for breadmaking due to its superior milling qualities, baking characteristics and protein content. Organic wheat production is becoming more prevalent in Canada, due to increasing consumer demand for organic wheat products. Differences may exist in the baking and milling quality of wheat grown under conventional and organic management, a result of the dissimilarity between organic and conventional soil and crop management practices. Five CWRS cultivars released from 1885 to 1997 were grown under conventional and organic management and were assessed for their breadmaking potential. Several traits were investigated, including test weight, protein content, flour yield, kernel hardness and several mixograph parameters. Test weight was higher under conventional management, while no differences in protein content were observed between organic and conventionally grown wheat. Higher sodium dodecyl sulfate sedimentation (SDSS) volume, a reflection of gluten strength, was observed under conventional management, while there was a trend towards higher dough strength under organic management. Cultivars differed in grain protein, flour yield, kernel hardness and mixograph parameters, with Park and McKenzie superior to the others, particularly Red Fife, a much older cultivar. Management×cultivar interaction effects suggest that cultivars exhibit somewhat different baking characteristics when grown in the two management systems. There was no evidence that older cultivars (developed prior to the widespread use of pesticides and fertilizers) are better suited, in terms of breadmaking quality, for organic production.

Grazing Systems

Clean grazing systems for sheep have been developed to minimize helminth challenge to susceptible lambs. Provision of clean grazing relies upon effective control of overwintering helminth infection on pasture and particularly in the post parturient ewe. During early lactation ewes immuno-competence is reduced resulting in the excretion of helminth eggs for approximately six weeks post lambing (Thomas, 1973). Control of this source of infection may be achieved by strategic anthelmintic administration while overwintering pasture infection may be avoided by use of pasture which has not carried sheep in the previous year.Prophylactic anthelmintic administration is unacceptable under an organic management system and consequently alternative strategies must be sought to eliminate the ewe as a source of infection. The objective of the present study was to evaluate strategic transfer of ewes and lambs to a silage aftermath as a means of minimizing helminth challenge to susceptible lambs.

Este trabalho analisou a variação no potencial das formigas como agentes anti-herbívoros em plantas de café (Coffea canephora Pierre) e guandu [Cajanus cajans (L.) Millsp]. Foram usados ovos artificiais, simulando a presença de insetos herbívoros, e solução de açúcar, para aumentar a atividade de formigas, em experimentos de campo. As plantas de café e de guandu possuíam diferentes níveis de atividade de formigas, pois as últimas eram atacadas por membracídeos que atraíam mais formigas. A atividade das formigas foi monitorada após aplicação de solução de açúcar e a remoção de ovos artificiais foi medida após 24 e 48 horas. A solução de açúcar aumentou significativamente a atividade de formigas em plantas de café e de guandu. A remoção dos ovos artificiais foi significativamente maior em ramos com formigas do que sem formigas para as plantas de guandu. A adição de solução de açúcar aumentou a remoção de ovos artificiais em plantas de guandu, mas não em plantas de café. O tratamento com solução de açúcar e a presença de membracídeos em guandu tiveram efeitos similares sobre a atividade de formigas. Este estudo mostrou que a aplicação de solução de açúcar pode ser utilizada para simular a presença de membracídeos sobre as plantas, aumentando a atividade de formigas. Isso permitiu a avaliação de seu potencial como agentes anti-herbívoros, através de experimentos que simulam a presença de insetos sobre as plantas. Potential of Ants (Hymenoptera: Formicidae) as Anti-herbivore Agents in Cultivation of the Coffee (Coffea canephora Pierre) and Pigeon Pea [Cajanus cajans (L.) Millsp] Abstract. This study analyzed the role of ants as anti-herbivore agents in Coffee (Coffea canephora Pierre) and Pigeon Pea [Cajanus cajans (L.) Millsp] plants in agroecosystem under organic management. In these plants we used artificial eggs and sugar solution in experiments that simulated the presence of herbivore insects. Coffee plants did not possess any natural attractive that could intensify foraging activity of ants, but pigeon pea plants were infested by treehoppers which attracted ants. Activity of ants was surveyed after sugar solution application and artificial eggs removal was measured 24 and 48 h after start of the experiments. Sugar solution sprinkled on plants foliage increased significantly the activity of ants on coffee and pigeon pea plants. The removal of artificial eggs was significantly greater in branch with ants than without ants for pigeon pea plants. The sugar solution addiction resulted in greater artificial eggs removal in pigeon pea plants, but not in coffee plants. The treatment with sugar solution and presence of treehoppers had similar effects on the activity of ants on the plants. This study showed that the application of sugar solution can be used to increase activity of ants on plants as well as the potential of ants as anti-herbivore agents can be evaluated in experiments that simulate the presence of insects on the plants.
