Comportamiento agroproductivo de tres cultivares de Glycine max (L.) Merril

Abstract

Objective: To evaluate the agroproductive performance of three cultivars of Glycine max (L.) Merril on a loose brown soil without carbonate. Materials and Methods: The research was conducted in a farm in the Las Tunas municipality, Las Tunas province, under field conditions. A randomized block design was applied with three treatments and three replicas. Plots with an area of 11,2 m2 were used. The distance between replicas was 1 m. The seed had 98 % germination. The cultivars Incasoy-1, Incasoy-26 and Incasoy-2 were studied. During the vegetative cycle of the crop, the variables number of pods per plant, number of grains per plant, weight of 100 grains, yield in t ha-1, were evaluated. Results: The lowest number of pods per plant corresponded to cultivar Incasoy-2 and the highest one was shown by Incasoy-1, which differed statistically from Incasoy-26. The highest yield was obtained in cultivar Incasoy-1 (1,75 t ha-1), which differed from the others, and the lowest value was recorded in Incasoy-2 (0,60 t ha-1). All the cultivars reached profits in their production. The treatment that provided the highest profit was Incasoy-1, with results of 121 250.00 pesos per hectare, and cost of $0,10 per produced peso. Conclusions: The highest agricultural yield was for cultivar Incasoy-1 (over 1 t/ha) and the lowest yield for Incasoy-2. In turn, the highest net profit corresponded to Incasoy-1, as well as the lowest cost per peso.
