| This paper describes the data obtained for the growth of sugar cane, Variety Co 419, and the amount and rate of absorption of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and silicon, according to the age of the plant, in the soil and climate conditions of the state of S. Paulo, Brazil. An experiment was installed in the Estação Experimental de Cana de Açúcar "Dr. José Vizioli", at Piracicaba, state of S. Paulo, Brazil, and the soil "tèrra-roxa misturada" presented the following composition: Sand (more than 0,2 mm)........................................................................ 8.40 % Fine sand (from 0,2 to less than 0,02 mm)................................................. 24.90 % Silt (from 0,02 to less than 0,002... |

| In previous publications Bishop & Crisp (1957, 1958) described the distribution of Elminius modestus on the coasts of France, based on surveys made in 1953 and 1954. Further information including some observations made in 1955 was given by Bishop, Crisp, Fischer-Piette & Prenant (1957). Elminius was shown to be centred on three main areas; the Channel coast east of Cap de la Hague, the river systems of North Brittany, and the Rade de Brest. Further south scattered individuals only were to be found, nowhere in sufficient abundance to allow the majority to breed. Bishop & Crisp (1957) pointed aut that the scarcity of Elminius on this part of the Brittany coast was surprising, since there are numerous suitable estuaries and harbours and an... |

| A seringueira é uma planta cujas estacas normalmente enraizam com muita dificuldade. Daí o autor ter estudado uma maneira de multiplicar essa planta por meio de estacas, pelo estrangulamento de sua haste, com um fio de arame bem apertado. Decorridos vários dias após tal operação, as estacas são cortadas logo abaixo do callus formado e plantadas em areia. Vários ensaios foram realizados no Instituto Agronômico do Norte, para estudar em que lugar da haste deve ser feito o estrangulamento, bem como quantos dias depois da operação devem as estacas ser colhidas. Os resultados mostram que o estrangulamento deu melhores resultados quando feito logo abaixo de uma gema ou do ponto de inserção de uma ou de duas fôlhas, e que a colheita das estacas deve ser feita... |

| This paper will take a new look at budgeting. It will be argued that with the development of linear programming, budgeting can be seen to have several disadvantages as a research tool. The development of linear programming as an aid to farm management research will then be examined. This examination will lead to the development of a slight refinement of conventional budgeting methods. This refinement may reasonably be termed parametric budgeting. |

| The new species described below belongs like St. leplocaulis Brem. (in Nova Guinea, new ser., 8: 129. 1957) to the subgenus Telrastichum, which is characterized by the presence in each of the ovary cells of circ. 60 ovules arranged in four rows and by the lower flowers of the inflorescence being subtended by ordinary leaves. The new species is easily distinguishable from St. leptocaulis by its larger and relatively wider leaves and by its obovate-orbicular bracts. Staurogyne latibracteata Brem. n. spec. ad subgenus Tetrastichum pertinens, caule ascendente et anthisre appendiculatis ad St. Neesii (Vidal) C. B. Clarke ex Merr., St. rivularem Merr. et St. leptocaulem Brem. accedens, caule pilis capitatis vestito praesertim St. Neesii et St. leptocauli similor... |
