Effect of different biostimulants in the yields of common beans

With the objective of to evaluate the effect of different biostimulants in the increase of morphophysiological and productive indicators of common bean, the following research was carried out at the collective farmer "Joe Westbrook" in Sancti Spiritus, Cuba, from November 2014 to February 2015. The sowing of cv. Bat-304 was carried out manually form at a distance of 0.80 m between rows and 0.15 m between plants. The following treatments were evaluated: Efficient Microorganisms (ME-50), ME-Agitado and LEBAME, Fitomas E, Biobras-16 (R) and a control (without application). The evaluated variables were: plant height, stem diameter, number of leaves per plant, dry matter, grains per pod, mass of 100 grains and yield. The results showed that the foliar application of the different biostimulants increased the morphophysiological and yield indicators evaluated. The highest yields when biostimulants ME-50 and Biobras-16 (R) were applied, with 2.01 and 2.00 t ha(-1) respectively.
