Abstract:

The primary focus of this paper is on the effects of tillage and residue management on some diseases of cereal and oilseed crops in western Canada. In this region, reduced tillage lowers the impact of some root diseases but increases the impact of foliar diseases on cereals. Published data showing evidence of the effect of reduced tillage on diseases of oilseed crops is scarce. Diseases that were less economically important under higher tillage regimes may become more important with reduced tillage, but location and local environment largely influence which diseases will be present.

Abstract:

The integrated crop-livestock production system provides most of the food needed by the people of China. Five types of integrated production systems are recognised; rangeland, grain crops, crop/pasture, agro-silvopastoral and ponds. Development of more sustainable and integrated crop-pasture-rangeland-livestock production systems has been recently achieved. Demonstrations of the integrated systems at household, village and regional levels are occurring for rain-fed agriculture on the Loess Plateau, the Hexi Corridor, north-western China and the Karst region of Guizhou Province, south-western C

Abstract:

The West Side of California's San Joaquin Valley is one of the most productive agricultural regions of the world. The leading crops of this region include processing tomatoes, cotton, onions, garlic, cantaloupes, and lettuce, which are grown on over 570,000 acres annually. During the past 30 years, land use patterns on the West Side have changed considerably. More than 60% of the acreage in this area was typically planted to wheat, barley, and safflower in 1965, whereas in 1994 these crops were grown on 7% of the area. The intensification in the production of high value crops has led to fewer

New technologies such as differential global positioning systems (DGPS) and geographical information systems (GIS) are making it possible to manage variability in soil properties and the microenvironment within a field. By providing information about where variability occurs and the patterns that exist in crop and soil properties, DGPS and GIS technologies have the potential of improving crop management practices. Yield monitoring systems linked to DGPS receivers are available for several types of horticultural crops and can be used in variety selection and/or improving crop management. Precis

Abstract:

There is currently considerable interest in the use of cover crops to improve the productivity and sustainability of agroecosystems in California. Adoption of cover crops into San Joaquin Valley row cropping systems has been slow, however, largely because growth characteristics of potentially suitable cover crop species and mixtures have not been identified for the tight windows of opportunity that exist within the region's intensive rotations, and because of uncertainy about the amount of water required to grow a cover crop.

Plant roots are an integral part of soil ecosystems and contribute to various services, including carbon and nutrient cycling, weathering, and soil formation. They also modify soil physical properties (e.g., soil water content, pore size distribution, and bulk density) and impact subsequent crops’ growth. Cover crops have been reported to improve soil and environmental quality by reducing nutrient losses, improving soil water content, and increasing soil organic matter. Understanding the complex interactions between cover crop roots and soil (RS) is of utmost importance. However, cover crop RS

In order to improve N best management practices in southwestern Ontario vegetable farming, the effect of cover crops on N dynamics in the fall and spring prior to sweet corn planting and during sweet corn season was assessed. The experiment was a split plot design in a fresh green pea – cover crop – sweet corn rotation that took place over 2 site-years at Bothwell and Ridgetown in 2006–2007 and 2007–2008, respec

Abstract. Sustainable no-till practices utilize cover crops to protect the soil surface and to improve soil properties. Proper cover crop management is the key for successful planting of the main crop directly into cover crop residue without interfering with planting operations. In the Southern United States, the recommended time to plant cash crops into desiccated residue cover is typically three weeks after cover crop termination when the termination rate exceeds 90%; this minimizes nutrient competition between cover and cash crops. The standard method to manage cover crops is mechanical ter

Abstract:

Cover crops can provide many benefits in agroecosystems, including the opportunity for improved weed control. However, the weed suppressive potential of cover crops may depend on the species (or mixture of species) chosen, and the method of cover crop termination and residue management. The objective of this study was to determine the effects of cover crop mixture and mechanical termination method on weed biomass and density, and relative crop yield in an organic cropping system. A field experiment was conducted from 2009 to 2011 near Mead, NE, where spring-sown mixtures of two, four, six, and

Abstract:

Horticultural crop management strategists of the past have routinely chosen to remove root-related limitations to productivity by operating at high fertility levels and by excessive irrigation of well-drained soils, without much concern for fertilizer losses to the environment. The relatively low cost of fertilizer as a component of the overall production cost has justified, at least on economic tens. the liberal application of fertilizer on most horticultural crops. However, inefficiencies in fertilizer use can no longer be neglected as society becomes increasingly aware and critical of the v

Abstract. Practices to improve the efficient use of water are of high relevance in rainfed agriculture. The effect of cropping systems on soil available water and water use of crops grown in a humid and temperate climate was investigated. This study was conducted at the University of Minnesota Southwest Research and Outreach Center near Lamberton, Minnesota, during three growing seasons. The treatments studied included an extended 4-year crop rotation (oat/alfalfa-alfalfa-corn-soybean) using organic inputs or high external (mineral) inputs and the traditional 2-year corn-soybean rotation, with

Abstract The objective of this work was to evaluate the physical quality of an Oxisol under no-tillage subjected to different crop rotations and crop sequences. The experiment was carried out in a clayey Oxisol, during six years, in a randomized complete block design, with strip plots and three replicates. The following physical indicators of soil quality were evaluated: soil density and carbon content, as well as mean weight diameter and tensile strength of aggregates. Treatments consisted of three summer crop rotations - corn/corn (Zea mays), soybean/soybean (Glycine max), and soybean/corn -

Abstract:

AbstractOrganic farming has been historically dependent on conventional tillage operations to convert perennial pasture leys to annual crop rotations, incorporate crop residues, compost and cover crops, as well as to mechanically kill existing vegetation. Conventional tillage, however, has long been known to lead to soil degradation and erosion. A recently developed no-till organic production system that uses a roller–crimper technology to mechanically kill cover crops was evaluated in two states in the western United States. In Washington, pumpkins (Cucurbitaspp.) grown in a no-till roller–cr

AbstractOrganic systems in the southeastern USA offer unique challenges and solutions to crop production due to regional soil and climate characterized by highly weathered soil types, high precipitation and the capacity to grow cover crops in the winter. Recently, the interest of producers and researchers in high-residue cover crops and conservation tillage systems has increased. Various designs of the roller–crimper to manage cover crops have been invented and demonstrated to growers in the southeastern region of the USA over the past 17 years.

Abstract:

In plasticulture, raised beds, plastic mulch, rowcovers, and fertigation are used to accelerate crop growth and improve crop quality by providing heat, nutrients, and water at near-optimum levels. Because plasticulture is intensive and input costs are high, profits are maximized when high-value crops are grown. For herb crops, plasticulture can also be used to control weeds without herbicides, to prevent soil contamination by rain splashing, and to prevent rooting of side branches. In a studies of Echinacea species, root yields in the first year were improved by 35% to 77%. Other crops found t
