ROMERO, Aracelis; RUZ, Raquel  e  GONZALEZ, Martha. Evaluation of seven soybean (Glycine max) cultivars under the edaphoclimatic conditions of the Majibacoa municipality, Las Tunas. Pastos y Forrajes [online]. 2013, vol.36, n.4, pp. 459-463. ISSN 0864-0394.

The research was conducted in a cooperative of credits and services (CCS) of the Majibacoa municipality, Las Tunas province, in order to evaluate the productive performance of seven soybean (Glycine max (L.) Merrill) cultivars on a lixiviated Reddish Brown Fersialitic soil. The evaluated cultivars were: Jupiter, Conquista, BR-4, Canada, Inifat-382, Williams and Incasoy-1. A randomly block design was used, with four replications per treatment and 5 x 2-m plots with 1 m of distance between replications. Sowing was carried out at 4 cm of depth, with a distance of 0,50 m between rows and 0,10 m between plants. Two irrigations per week were applied and fertilization was used with a complete formula at the time of sowing, with doses of 80 and 100 kg of phosphorous and potassium/ha, respectively. Fifteen days after the emergence of plants, the maximum height was obtained in the cv. Jupiter and the lowest height in Canada. At 30, 45 and 60 days, Jupiter, Conquista and Inifat-382 were significantly higher than the other cultivars. The highest grain yield was obtained in cvs. Jupiter and Inifat-382 (2,11 and 2,19 t/ha, respectively) and the lowest, in Incasoy-1, which was in correspondence with its lowest number of pods per plant. It is concluded that the most outstanding cultivars were Jupiter and Inifat-382, because they achieved the highest plant height and the best grain yield; while the cv. Incasoy-1 was the one with the lowest yield
