O experimento foi realizado na FCAV- UNESP utilizando-se o delineamento em blocos ao acaso no esquema fatorial (2 x 3) com quatro repetições nos dois anos agrícolas. Os componentes avaliados foram na máquina, no solo e na planta. O diâmetro do colmo, a altura de inserção da primeira espiga e a altura de plantas de milho resultaram em maiores valores para o sistema de adubação na semeadura. O número de fileiras, espigas viáveis, índice de espiga, estande final, biomassa seca no solo, produtividade, fluxo de palha, fluxo de sabugo, fluxo de grãos e as perdas na colheita não foram afetados pelos sistemas de adubação e pelos consórcios, na cultura do milho. A avaliação da distribuição longitudinal de plantas de soja na semeadura, e o fluxo de material de soja na colhedora não foram afetados pelos sistemas de adubação e pelos manejos dos resíduos.

The experiment was done at FCAV-UNESP with totally randomized delineation, on factorial scheme (2x3) with four repetitions during the two agricultural years. The components evaluated were: machine, soil and plant. The stalk diameter, the insertion height of the first cob and the height of corn plants presented higher values for the fertilization system at sowing. The number of rows, viable cobs, cob rate, final stand, dry mass on soil, productiveness, flow of straw, cob and grains and the losses in the harvest were not affected by the fertilization systems and by the consorts in the corn crop. The evaluation of longitudinal distribution of soy plants at sowing and the soybean material flow in the harvester were not affected by the fertilization systems and by the management of chaff. The soybean plants presented higher height of insertion of the first string bean and the number of string beans in the knife roller management. The soybean yield was not affected.

Writing the Royal Consort in Stuart England

Linnell, Anna-Marie January 2016 (has links)
This dissertation examines the literature of royal consorts in Stuart England. Critics and historians have devoted considerable attention to the creation of the monarch’s image during this tumultuous period, which witnessed two revolutions and the explosion of print. We know that the Stuart monarchs embraced different forms of visual media – including pageantry, portraiture and print – to disseminate their image within the court and to a broader public. However, the extensive literature about the royal consorts remains under-examined. My thesis makes an original contribution to scholarship by exploring what texts were written about the royal consorts, by whom, and how these writers constructed images of the royal consorts that participated in broader debates over the status of the monarchy. The dissertation is divided into two main parts. Part 1 comprises six chapters that analyse succession writing, when a new monarch came to the throne and established their iconography for the new reign. I draw on hundreds of texts that were printed about the Stuart consorts at these moments. These writings span a variety of genres, from poems and plays to sermons and political pamphlets. I investigate the literature of each succession in turn, analysing the main themes and motifs that emerged. This approach enables me to uncover a swathe of anonymous and under-utilised literature, but also re-interpret works by more canonical writers such as Aphra Behn. I ask how the royal consorts themselves, their spouses and members of the public could influence the creation of the royal consorts’ images at these moments. Critically, I also compare the conventions that were used to describe the consorts across the century. Part 2 analyses how writers re-constructed ideals for the royal consorts in Restoration England, as debates about the structure of the monarchy came to be more explicit. Chapter 7 concentrates on images of Henrietta Maria when she returned to England as Queen Mother. Chapter 8 asks how writers adapted former models of representation to praise Catherine, the infertile queen, when it became clear that she would not bear an heir. Finally, Chapter 9 examines the numerous secret histories and romances that were authored about Mary Beatrice’s purported behaviour during her exile in the 1690s. These chapters highlight the continued importance of these women and examines how writers constructed their legacies. As a whole, the literature about the royal consorts reveals a dynamic project as part of which authors engaged with and adapted earlier models of writing. This enabled them to address broader questions about changes in the nature of the Stuart monarchy and political life.
