Influência da epoca de semeadura sôbre rendimento do rabanete

During 1952 and 1953 the author observed that radish, Raphanus sativus, L, developed rapidily in the warmer and damper period of the year and endured the lower temperatures. The yiel of leaves counted from 20 to 40% of the plant weigth.

"Influencia da época de semeadura sôbre o rendimento do repôlho"

The author carried out a study on the behavior of cabbage for a period of two years (1952 and 1953). From the results obtained it was concluded that, cabbage, Brassica oleraceae, var. capitata, developed better during the cooler season of the year, that is, from April to June and, the yield decresed from the beginning to the end of the sowing time, that is, from April to Ocotber.

Cana forrageira competição de variedades

At the 2nd. Department of Zootechny of the E. S. A. L. Q., in Piracicaba, between 1953 and 1955 an experiment of sugar cane varieties was carried out, with the objective of discovering varieties to substitute "Taquara" (the variety most widely used) and Co 290 (the most recommended). The former was condemned as being too susceptible to cane smut and the latter showes signs if degeneracy. In the experiment, 8 varieties were used with 3 replications in randomized blocks, in 3 rows each. The cane was crop not in the same period, but when they were at comparable ripeness (70 cm of apparent culm). They were crop twice during the year, with a sharp hoe near the soil. The summary of the results and the statistical analyses are shown in tables 1 to 3, showing the possibility of there being 3 groups: A superior one composed of Co 419, a median one, in decreasing order of production, composed of Kassoer, CB 40-69. Co 413, IAC 36-25 and POJ 161 and an inferior group composed of Co 290 and Taquara. There is a possibility that POJ 161 belongs to the last group. Nevertheless, this variety is not recommend because of its susceptibility to smut. As Kassoer is more healthy, vigorous and enduring than Co 419 and other varieties, it is shown recommendable. IAC 36-25 is being recommended presently for forage since its productions is lower than Kassoer, placing 5th productivity, although statistical significance was not detected. As our final conclusions, Co 419, Kassoer, CB 40-69, Co 413 and IAC 36-25 can be planted as forage while POJ 161, Co 290 and Taquara should not. The last two were exactly those used as forage reserve in the 2nd. Department at the beginning of the experiment.
