Abstract:

The degradation of soil quality due to undesirable farming practices has reached alarming scales in the Eastern Cape and this has had negative repercussions on soil productivity and the environment in general. There is growing evidence that conservation agriculture (CA) practices involving minimal mechanical disturbance, maintaining permanent surface cover and embracing diverse crop rotations increase soil organic carbon (SOC) and therefore has potential to mitigate soil quality deterioration. A study was carried out at two sites located in two ecotopes to investigate the effects of crop resid

Effects of different weed control practices on soil quality in mediterranean crops This research approaches the question of weed control sustainability, from the point of view of soil quality maintenance and enhancing. A big choice of practices and products for weed control are available nowadays, but the actual definition of "sustainable practice" not always considers soil fertility. Soil processes timescale is wider than the productive, commercial and legislative ones. Also the definition of survey protocols is a process slower than the evolution of weed control methods.

Durum wheat (Triticum durum Desf.) is produced primarily in the Northern Great Plains and the Pacific Southwest of the United States. Current germplasm is predominantly of the spring growth habit. The objective of this study was to determine the feasibility of winter durum production in Virginia based upon both yield and quality parameters. Adaptation and yield potential of available winter durum lines were assessed from 1993-1998, in three physiographic regions in Virginia. The highest average durum yields were produced in the northern piedmont plateau at the Orange County location. Winter d

Cotton (<i>Gossypium hirsutum</i> L.) is a low residue crop, that may not provide sufficient surface residue to reduce erosion and protect the soil. A winter annual cover crop could alleviate erosion between cotton crops. Field experiments were conducted to evaluate selected winter annual cover crops for biomass production, ground cover, and N assimilation. The cover crop treatments were monitored under no-till and conventional tillage systems for the effects on soil moisture, cotton yield and quality.

Abstract:

Quality protein maize (QPM) has enhanced levels of two essential amino acids, lysine and tryptophan compared to normal maize. This makes QPM an important cereal crop in communities where maize is a staple crop. The main abiotic factor to QPM production is drought stress. Little information is available on the effect of drought stress on QPM. Therefore, the objectives of this study were to: (i) conduct diversity analysis of QPM inbred lines using morpho-agronomic and simple sequence repeat markers, (ii) screen available QPM inbred lines and F1 progeny for tolerance to seedling drought stress, (

Abstract:

The objective of this study was to compare the nutrient status of full scavenging and semi-scavenging village chicken production systems. The semi-scavenging chickens were given broiler finisher mash between 14-24 weeks of age, whilst the full scavenging relied on natural foraging. The study also sought to compare the quality of meat from chickens from the two systems. After slaughtering the chickens, the crop contents were physically separated and analysed for chemical composition. Meat pH and colour were measured on the breast muscle of individual carcasses and a consumer sensory evaluation

Abstract:

Several dynamics have contributed to the increasing conception of higher education as a service, universities as service providers, students as customers and quality as value for money. Quality management has been pursued as a means to promote accountability and is primarily driven by student satisfaction surveys. This has resulted in the dominance of the retrospective customer model for the management of quality in higher education (Biggs, 2001) with emphasis on accountability and ‘value for money’ for the student customer. At the same time, decreasing public funding and a growing student dem

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>This study used precision agriculture (AP) techniques to understand the dynamics of physical, chemical and biological soil for different winter management systems after three years of cultivation, to serve as the basis of the definition and indication of Intelligent Management Plans (PMI) in an efficient and practical way. The work was conducted in the city of Frederico Westphalen, RS, were evaluated ten winter management systems - fallow (PO), wild oat (Ap), white oat (AB), ryegrass (AZ), forage turnip (NF) vetch (E), white lupine
