Response of the Bean Crop (Phaseolus vulgaris L.) to the Application of Efficient Microorganisms in Guantánamo Municipality

Abstract

An experiment was conducted on the farm of Radomil Ruban Guerrero, a member of the Luis Rustán Rodríguez Credit and Services Cooperative (CCS) in Guantánamo, Cuba. The objective was to evaluate the growth of the bean (Phaseolus vulgaris L.) var. Cufig-48 using Efficient Microorganisms (EM). Four treatments were used in a randomized block design: T1 (control without application), T2 (seed soaked at 2%), T3 (foliar application of EM every 7 days after soaking), and T4 (foliar application without soaking). Yield components such as the number of pods per plant and 100-bean weight were analyzed. The results indicated that treatment T3, which included foliar application of EM, significantly outperformed the control and the other treatments, achieving a yield of 1.33 t/ha and profits of $16,963.13.
