Abstract
The authors carried out joint analyses of data referring to six experiments with varieties of sugar cane, carried out by SEGALLA and ALVAREZ in six locations in the State of S. Paulo, Brasil. The analyses showed that for cane or sugar yield, either for plant-cane or for plant-cane together with the first two ratoons, the best five varieties were CB 40-69, CB 41-76, CB 40-13, CB 40-19 and Co 419. The yield of sugar cane/for all varieties studied is given below, in metric tons produced in plant cane and the first two ratoons. Varieties Yield of sugar cane (tons/hectare) CB 40-69 205.2 CB 41-76 204.5 CB 40-13 199.4 CB 40-19 192.4 Co 419 192.1 CB 38-30 182.1 CB 41-70 181.5 Co 413 177.5 CB 38-22 174.4 CB 36-14 172.8 Co 290 166.6 CB 41-35 147.9 The least significant difference by Tukey's test, at the 5% level of probability, is A = 28.3 metric tons/hectare
