| その他の書誌記述: | An experiment was conducted to compare the traditional sorghum sowing method (single row) with double row method in the spring of 1992 under irrigation conditions in Rio Bravo, Tamaulipas, Mexico. A Complete Randomized Block design with a 2 x 5 factorial distribution was used with six replications; where the factors were: sowing method (doble and single row) and population density (187, 256, 342, 375 and 435 thousand plants/hectare). The hybrid Pioneer 8244 was used and planted at 0.80 m between rows. The parameters evaluated were plant height, panicle excertion, panic1e lenght and weight, grain number and moisture, weight of a thousand grains, grain yield and plant mortality. Mean separations were run using the Duncan's test. The grain yield and number per panicle were higher in double row method than in single row by 7.5 and 18.9 %, respectively; while grain weight and plant height showed higher values in single row than doble row. On the other hand, the weight and panic1e length decreased when population density increased in both methods, while panic1e excertion and plant mortality increased. |
