Efectos de dos sistemas de labranzas en los rendimientos del fríjol

The aim of this investigation was to evaluate the effect of two farming tilling systems with the use of coverage and application of Rhizobium in agricultural yield in the cultivation (Phaseolus vulgaris L.) “Velazco largo”. The economic and energy efficiency were analyzed the research conditions in the intensive farm of the UBP “Playuela”, in Majibacoa municipality, in Las Tunas Province, in the period from November, 2009 to January, 2010. There was used a randomized block design with three replicates. The were an area of 35 m2 in the plots. The results showed that farming allowed obtaining a 39% increase in crop yields over conventional tillage. This system allowed greater energy efficiency by reducing energy expenditure in humans, animals, and other supplies. The transformation of soil preparation technologies to conservation farming systems will allow the tillage systems of more economic and ecological sustainability of the production system in Playuela.
