Abstract

To evaluate the effect of a growth promoter on the productive behavior of the bean culture, four experiments were carried out in four agroecosystems of the province of Sancti Spíritus, Cuba. The experimental design used for the trials was the Latin Square with four treatments. The doses of VIUSID agro® evaluated were: 0.5; 0.8; 1.0 (L ha-1) and one control. The agronomic variables evaluated were: pods per plant, grains per plant, grains per pods, yield per plant (g), mass of 100 grains (g) and agricultural yield (t ha-1). In experiment one, the highest stimulant effect was achieved with treatments of 1.0 (L ha-1), with an increase in yields of 30.28% with respect to the control. In test two, the agricultural yield at doses of 0.8 and 1.0 L ha-1 exceeded the control by 29.35 and 35.32%, respectively. Similar results were obtained in experiment three, where the increases with respect to the untreated plants were 19.19 and 11.62%. Similarly, in trial four there was an increase in production over the control of 1.21 t ha-1 with the use of the higher dose. Foliar application of the VIUSID agro ® growth promoter significantly favored the bean crop productivity. The best performance doses were 1.0 (L ha-1) in experiments one and four, and 0.8 and 1.0 (L ha-1) in experiments two and three
