| A new variety of adlay (Coix lacryma-jobi L.) is being cultivated in the Slate of São Paulo, its chief characteristics being small height, oblong black seeds, and fair yield, especially in low lands, with abundant rainfall and high temperature. Some trials were conducted with this plant in four experiment stations of the Instituto Agronômico in the State of São Paulo. The yields were very variable from year to year and place to place. The following preliminary statements could be made with regard to highland conditions in this state: a) adlay should be planted in October-November ; b) spacing and rate of planting is not very important within the limits of 60-120 cm between rows and 8 to 33 g of seed per 10 m in the row, on account of the great tillering... |

| No trabalho de melhoramento de milho que, a partir de 1932, vem sendo conduzido pelo Instituto Agronômico de Campinas, procurou-se obter linhagens das mais diversas procedências e origens, tendo em vista a diversificação do material genético a ser eventualmente utilizado. Neste sentido, foram feitos esforços com o intuito de introduzir, no Estado de São Paulo, sementes de variedades, linhagens e híbridos cultivados alhures. Até o ano de 1951, haviam sido recebidas 1405 amostras, a maior parte das quais provenientes dos Estados Unidos e do próprio país. Da Colômbia, Peru e Bolívia, também foi recebido muito material. Ultimamente, deram ingresso numerosos híbridos efetuados pela Oficina de Estúdios Especiales, na Colômbia e no México, cruzando híbridos... |

| Comparative trials with experimental corn hybrids are being conducted, in the State of São Paulo, Brazil, by the Instituto Agronômico, at its Experiment Stations, at Campinas, Ribeirão Prêto and Pindorama. During the years from 1938 to 1950 a total of 119 trials were planted, only twelve of them having been eliminated due to severe insect attacks. Except 21 trials in randomized blocks and 2 in incomplete block designs, all the others were planted in simple lattice, with 4 replications. The individual plots, with few exceptions, had one or usually two 5 m rows each. Among the yellow flint Unes tested, L. 483 is, no doubt, the best. It has high combining ability and also excellent agronomic characters. The performance of some other lines, as L.278-1-1,... |

| Three locals corn varieties and two commercial hybrids were studied at ten different places, during three consecutive years, in comparative trials. Randomized blocks, and Latin square design were used in plots with 30 or 15 square meters. Hybrid H.3531 was more productive in localities with poor soils while in places with rich soils the Agroceres hybrid was better than the open pollinated varieties. No significant difference between these hybrids was observed. In these trials, hybrids H.3531 and Agroceres produced, on the average, about 400 kg/ha more than the open pollinated varieties, Cateto and Armour, with which they have been compared. |
