| The effect of different feeds in comparison with that of maize grains on the egg yolk color was observed. It was found that deep orange and yellow orange maize give satisfactory coloration to the yolk, respectively orange and yellow. The most intense color was observed when green feed was used in combination with deep orange maize. Green feeds as chicory, alfafa, cabbage, welsh onion and banana leaves and alfafa or chicory meal proved to be good in giving orange color to the yolk. Yellow yolk was obtained when Guinea grass or carica fruit were used in the ration. Carrot and beet without leaves did not give satisfactory color to the egg yolk. The observations with other feeds are being continued. |

| 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,... |

| This paper deals with the preliminary results of a sand culture experiment carried out to obtain physiological bases to study the fertilization of cassava in the State of São Paulo. On the other hand, the authors are interested in the possible influence of mineral nutrients in the quantity and quality of starch. Cassava (Manihot utilissima Pohl.), "Branca de Sta. Catarina" variety, was grown under the following treatments: NO PO KO, NO P1 K1, N1 P0 Kl, NI P1K0, N2 p1 Kl N1 P2 K1 and N1 P1 K2. A striking response to phosphorus was observed among the treatments. However, once secured the necessary phosphoric level to the plant, the production becomes limited by nitrogen; in other words, increase in yield can be accomplished only by raising the nitrogenous... |

| 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... |

| 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. |

| 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... |

| 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... |

| 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... |

| The inheritance of two characters in Manihot utilissima Pohl were studied. It was found that the leaves with narrow lobes V (Fig. 1) are dominant over leaves with large lobes v (Fig. 2) and that the brown coloration of the roots M (Fig. 5) is dominant over white m (Fig. 6). These two characters segregate independently, according to the dates recorded in tables III and IV. The phenotypic expression of the form of the leaves is largely dependent from the environment, the leaves with narrow lobes being replaced by leaves with large lobes in plants transported to a shady place under big trees. (Figs. 3 and 4). Thus reduction of light causes a change of dominance. |

| 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... |

| 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... |

| 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... |
