| O presente ensaio refere-se à adubação de Pinus oocarpa Schiede. Foi instalado em solo Latossolo Vermelho Escuro Distrófico originalmente sob vegetação de cerrado, no município de Assis, São Paulo. Através de medições periódicos de altura e DAP (diâmetro à altura do peito) das árvores, foram verificados os efeitos da adubação NPK, calagem, S, B e Zn sob delineamento experimental de blocos casualizados com quatro repetições. Pela análise estatística dos últimos dados de altura e diâmetro, quando as plantas estavam com 3 anos, conclui-se que: a adubação NPK proporcionou um aumento significativo no desenvolvimento das plantas em altura e diâmetro; a adubação NPK + calagem aumentou significativamente a altura; a adubação NPK + calagem + S aumentou... |

| Throughout the past three decades, since World War II, development has been viewed as an important goal of national life for the poor and rich nations alike. The emerging nations of Africa, Asia and Latin America have come to see development as a continuation of the struggle that has won them independence. Development of these nations is thus often associated with the ever continuing struggle to remain free from alien domination. The post World War II era was consequently characterized by an active pursuit of economic development. As the LDC's plunged into planning for development, the developed nations while pursuing their own goals have shown an even greater tendency and preparedness to assist the low income countries attain their goals of improving... |

| In principle, the Group regards long-run market forces as the best guide to resource allocation, not only within existing production units, but also between sectors. However, in practice they perceive many instances of market failure in the rural sector which justify government intervention either on efficiency grounds or on equity grounds. They aggregate these intervention/assistance measures into sets and devote a chapter to each set. The new, novel and controversial aspects of assistance are highlighted in these comments. The Group discussed price support and underwriting schemes, input subsidies and related issues, natural disaster relief, income tax averaging, product promotion and export inspection services in Chapter 5 and research, extension and... |

| The Report commenced, appropriately, by addressing the federal contract within which Australian agricultural policy is set. The Australian Constitution limits what can be done by the Commonwealth and State Governments and establishes procedures for settling arguments about where jurisdictions lie. There is a wider constitutional framework than the Constitution itself. It includes, for example, the Australian Agricultural Council which is the major means of co-ordinating powers and resolving conflicts between the Commonwealth and states in the field of agricultural policy. The federal contract also includes the wide range of co-operative approaches to policy, such as statutory marketing intitutions and the complementary legislation which supports them. The... |

| Agricultural policy has been analysed systematically in Australia but the process of policy formation is not well understood. Distributional dimensions of policy issues influence decisions and policy analysts might improve their performance by better identification of these dimensions without neglecting basic efficiency criteria. These propositions and the functions of policy advisers are considered in this paper. |

| Domestic agricultural policy and trade policy are closely linked. Thus, research, including long-term forecasting activities, must take into account the domestic as well as international implications of trade policy issues. The seventh meeting of the Consortium on Trade Research on June 23-24, 1983, in Ottawa, Ontario, Canada, focused on the problems facing international agricultural trade in the eighties; current research efforts at the U.S. Department of Agriculture, Agriculture Canada, and the Organisation for Economic Co-operation and Development (OECD) Secretariat; and the status, problems, and applications of long-term forecasting models. |

| Verificou-se nos tres sistemas de manejo (drenagem natural com lamina de irrigacao Li) (aproximadamente igual ao uso consuntivo das culturas); drenagem com manilhas, com a mesma lamina de irrigacao; e drenagem com manilhas, com lamina de irrigacoa igual a 1, 2, Li>), uma elevada influencia das chuvas no processo de lixiviacao dos sais, o que abre boas perspectivas para o aproveitamento de agua salina para irrigacao, nas condicoes em que os experimentos estao sendo realizados. Nos testes, tem sido utilizados os capins elefante e Panicum colaratum. |
