The proper mineral fertilization of guava orchards under intensive management, is a major factor in productivity and monitoring the nutritional status of the plants contributes to the efficiency of this agronomic practice. The aim of this study was to investigate different doses of nitrogen and potassium in the nutritional status of guava 'Paluma'. The experiment was conducted at Vista Alegre do Alto, Sao Paulo, in a 7 year old irrigated orchard, managed with fruiting pruning during four consecutive growing seasons. The soil is a dystrophic Ultisol. The experimental design was randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization promoted increased levels of leaf N and Mn and the decrease in the levels of P and B; effects observed from the second to the fourth production cycle. Nitrogen fertilization increased the Ca and Mg levels, respectively, in the second and third cycle. Except for the first production cycle, K and Mn foliar concentrations increased with increasing potassium fertilization, whereas the levels of Mg, in the second and the fourth cycle, decreased as a function of fertilization.

The nutrition of the orchards is the major factor of productivity, being necessary to know the proper doses of fertilizers and their influence on fruit quality attributes for industrialization. This study evaluated the effects of different doses of nitrogen and potassium on the productivity of guava trees and also on the values of pH, soluble solids (SS), titratable acidity (TA) and pulp/kernel ratio of guavas. The experiment was conducted at Vista Alegre do Alto, SP in an irrigated 'Paluma'guava orchard, 7 years old, managed with pruning during three consecutive cycles of production. The soil of the area was dystrophic Ultisol. The experimental design was the randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization increased productivity and the pH of the fruit, being explained by the quadratic polynomial regression models; reduced linearly the pulp/kernel ratio and do not influenced the SS and TA values. On the other hand, potassium fertilization and N x K interaction had no significant effects on productivity and the other characteristics evaluated.

Glauber Rocha’s arrival at Rio de Janeiro can be considered a milestone for the Brazilian Cinema Novo movement in the early 1960s. In 1959, Glauber starts his collaborations in the Suplemento Dominical do Jornal do Brasil. This paper examines Rocha’s major contributions in this newspaper for the purpose of pointing out the strategies and formulations of the young intellectual from Bahia to promote a debate on the forms of modern Brazilian cinema and its relationship to other art forms in the 1960s.

In late 1950, the young Glauber Rocha, still without having directed any of his films, becomes the main cultural critic of the Jornal da Bahia in Salvador, Bahia. His film critic activity falls within the symbolic local disputes and his texts published become an active voice in the cultural field of Bahia. With a considerable apparatus of the press in his favor, the performance of the young critic Glauber Rocha allows to discuss: the role of public intellectual and media production and dissemination of ideas by the newspapers at the turn of the 1950s to the 1960s, a time of intense political, social and cultural changes in Brazil.

In the early 1960s, after his experience as a film critic in the Jornal da Bahia, the young Glauber Rocha began his collaboration in the Suplemento Artes e Letras of Diário de Notícias in Salvador. Inserting itself the symbolic disputes in defense of a film art of authentic Brazilian nuance, the activity of the critic Glauber Rocha represents a voice that demarcates the internal tensions of the field of cinema in Bahia and outlines, in the form of genesis, his most famous manifesto, “An esthetic of hunger” (1965). For this analysis were focused mainly two critics: “Experiência ‘Barravento’: confissão sem moldura”, published December 25-26, 1960, and “Luz Atlântica, 1962”, published in December 31, 1961.
