| This paper deals with the determination of the content of macronutrients in pulp and beans of three coffee varieties, namely 'Mundo Novo', 'Caturra Amarelo' and 'Bourbon Amarelo'. Samples were collected in plantations located in the three types of soils herein most of S. Paulo, Brazil, coffee is grown, that is, "terra roxa legítima" (Ribeirão Preto), "massapé-salmourão" (Mocóca), and "arenito de Bauru" (Pindorama). The following main conclusions were drawn after statistical analysis of data obtained hereby. There is no statistical difference among the three varieties . Average contents of macronutrients, as per cent of the dry matter, are the following: N P K Ca Mg S bean 1,71 0,10 1,53 0,27 0,15 0,12 pulps 1.78 0,14 3,75 0,41 0,13 0,15 Samples collected... |

| This paper deals with different types of fertilizer applications in coffee hill in the moment of transfering the plants to the field. During the first year, irrigation was applied in the dry season. After one year, the following characters were analised: plant height; plant diameter; number of productive branches; lenght and number of nodes in the first branch of the plant. The results obtained can be summarized as follows: the irrigation employed did not affect the treatments and mineral fertilizers combined with organic fertilizer were better than the others treatments used for comparisons. |

| Four years of inbreeding and its effects on fertility, hatchability, viability and egg production in the new bred "PPPP" (Pescoço Pelado Preta Piracicaba) (naked neck and black plumage, Piracicaba) were reported in this paper. It was observed a decrease in fertility, hatchability, viability and egg production as the inbreeding increases. The black plumage naked neck homozygozous chickens are now submitted to a system of uncontrolled mating in the hope that the natural selection will reduce some of the undesirable factors providing abundant material for pedigree control. |

| Depois de uma breve introdução, mostrando a importância que o gênero Tripsacum desempenha hoje nos problemas da origem do milho, fizemos um estudo detalhado da meiose na nova espécie Tripsacum australe, descrita recentemente por CUTLER e ANDERSON (3) e espécie esta encontrada em estado selvagem na América do Sul. Todas as fases da meiose mostraram-se normais e o número cte cromosômios, facilmente determinado nas fases diacinese, metáfase I, metáfase II, é de 18 para a fase haplóide. Esta espécie não difere, quanto ao número de cromosômios, da forma diplóide Tripsacum dactyloide e da espécie Tripsacum floridanum, estudadas por LONGLEY (5). Segundo MANGELSDORF e REEVES (10) as formas de Tripsacum encontradas na América Central têm 72 cromosômios e são... |

| A presente experiência foi realizada afim de se constatar a influência de dois tipos de milho comerciais, com grãos coloridos de amarelo-laranja, como precursores de vitamina A no crescimento de pintos. Um deles, denominado "Cateto", duro, de côr laranja muito forte e outro, chamado "Armour", dente, de coloração amarelo-laranja. Para testemunha foi empregado o milho "Cristal", duro e branco. Uma análise dos pigmentos dos dois tipos de milho com gráos coloridos mostrou que o milho Cateto, com grãos de coloração laranja forte, tem aproximadamente o dobro de pigmentos, tanto total como quanto a parte ativa em relação à vitamina A, quando comparado com o milho dente amarelo-laranja. Três lotes de pintos de 3 semanas foram utilizados, cada um recebendo a mesma... |

| The present paper discusses the data obtained in shade and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results, analysed statistically, can be summarized as follows: a) unshaded plots produced 17% more than shaded ones; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green (not ripened fruits) depends of the harvest time. When the harvest was retarded, the percentage of green fruits was higher in the shaded plots. When the percentage of green fruits was the same, both in shaded and unshaded plots, the percentage of ripened was higher and the percentage of dried fruits was lesser in the shaded plots as compared with unshaded ones; d) other comparisons as... |

| The AA. have studied, in this paper, the correlation of egg production in yearling R. I. R. pullets and the difference between the pelvic bones, an between the pelvic bones and keel. The distances between those bones were measured by the fingers. It was suggested an index = spread of pelvic x spread of keel bone. These three data were compared with the last 30 days production and with the production to date - six months. Comparisons have been made with 285 pullets. The AA. have concluded: (a) there is a positive correlation between the spread of the pelvic bones and the last 30 days (r = + 0,23 and pr = + 0,16); (b) there is not correlation of the distance between the pelvic bories to the keel and the last 30 days (r = + 0,11 and pr = - 0,01; (c) there is... |

| The results reported in this paper did not show statistical differences in production of seeds, number of plants and number of ears when corn fertilizer (combination of Chilean nitrate, superphosphate and potassium chloride) was applied either in the sowing furrow or in lateral furrows (one or both side). The treatments with fertilizer were better than the treatment without fertilizer used for comparisons. Cotton seed meal, used in combination with superphosphate and potassium chloride, placed in the sowing furrow, reduces statistically the number of plants in the row when compared with the treatments where applications were made only in lateral furrows. However, this reduction of plants did not affect significantly the number of ears and the production in... |

| 1) Um estudo sobre o modo de crescimento de alones tetraplóides de mandioca Vassourinha Paulista, obtido experimentalmente por meio da colquicina, foi feito em comparação ao crescimento de clones diplóides da mesma variedade. Três outros clones da mandiosa amargosa foram também incluidos na análise para comparação. As observações foram feitas nas hastes da primeira ramificação de cada planta e podem ser resumidas como segue: (Quadros n.°s 1 e 2). a) comprimento: Dos 6 clones tetraplóides analisados, 5 (n.°s 1, 3, 6, 5 e 7) tiveram um comprimento bem menor que o dos clones controles diplóides, mostrando assim serem plantas menores. Um único clone tetraplóide (n.° 15) teve um comprimento menor, porém com a média não estatisticamente diferente da média do... |

| This paper deals with data obtained in 1959 and 1960 in shaded and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results can be summarized as follows: a) the production, in shaded and unshaded plots, did not show differences statisticaly significant; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green, ripened and dry fruits depends of the year and of the harvest time. In the same harvest time, both for shaded and for unshaded plots the percentages in the shaded plots were higher for green fruits and lesser for ripened and dry fruits; d) coffee fruits brought from the field in the harvest time yielding up in unshaded plots as compared with shaded ones; e)... |

| This paper deals with the inheritance of black, blue and blue-splashed plumage in poultry. The material analysed had its origin in the State of Goias, Brazil and the genetical data seems to indicate the interaction of a single pair of genes as in the Andalusian fowls and other blue breeds. The dominant gene for blue egg is also present in the material and selection is now being directed to isolate a breed with blue plumage and blue eggs, named "Tudo Azul", what in Portuguese means all blue (plumage and eggs) and corresponds, in braziliian slang, to the expression "O. K." used in the United States. The commercial possibility of the chickens, as judging by its, laying capacity, is emphasized. |

| 1. The present work was carried out to study the effects of mineral nutrients in the yield as well as in the composition of cassava roots. The variety "Branca de Sta. Catarina" was grown by the sand culture method, the following treatments being used: N0 P0 K0, N0 P1 Kl, N1 P0 K1, N2 P1 K0, N2 P1 K1, N1 P2 K1, and N1 P1 K2, where the figures 0, 1, and 2 denote the relative proportion of a given element. The nutrients were given as follows: N = 35 grams of ammonium nitrate per pot loaded with 120 pounds of washed sand; P1 = 35 grams of monocalcium phosphate; Kl = 28 grams of sulfate of potash. Besides those fertilizers, each pot received 26 grams of magnesium sulfate and weekly doses of micronutrients as indicated by HOAGLAND and ARNON (1939). To apply the... |

| The effect of carotenoid pigments on the egg yolk color was studied in this paper. Three types of maize of known genetical constitution were used: Cateto, with deep orange endosperm; Armour, with yellow-orange endosperm and Cristal, with white endosperm. The carotenoid pigments of the two colored maizes were analysed: the total and both the active parts in relation to vitamin A and the zeaxanthin part showed to be practically double in the deep orange corn. The color of the yolk was orange when the ration had the deep orange corn and yellow in the case of the yellow-orange corn. The increase in shade was proportional to the amount of pigment present in the grains. If green feeds is added to the ration with white corn, the yolk becomes yellow or orange,... |

| The authors tried to check in this experiment the minimum of yellow corn necessary for preventing avitaminosis A in chickens. It was observed, in balanced ration with 50% of corn, that: a) 20% of dent and yellow grains and 30% of flint and white grains were insuficient to prevent avitaminosis A. b) 20% of flint and orange grains and 30% of flint and white grains or 40% of either colored grains and 10% of flint, and white grains did not show evident signs of avitaminosis A during the 12 weeks of the experiment. The ration containing 20% of flint and orange grains is pratically equivalent to the ration containing 40% of dent and yellow grains, regarding the content of pro-vitamina A. However, it was not possible to conclude if these dosage are sufficient to... |
