Effect of inoculation with Rhizobium sp., Trichoderma sp. and the application of biofertilizers on the yield of bean (Phaseolus vulgaris L.) Blanco Molinero

Abstract

The investigation was conducted at the Experimental Center of the Instituto Nacional de Innovación
Agraria (INIA) located in Lima-Perú, District of La Molina, the main objective consisted
in evaluated the effect of the combination of biofertilizers (Alopes Forte, Fertigigas Plus and
Biolac) and microorganisms (Trichoderma and Rhizobium) on grain yield of dry bean ‘’Blanco
Molinero ‘ based on a system of organic production, zero tillage and drip irrigation system. The
experimental design was completely randomized design with nine treatments and four repetitions.
Performance variables were evaluated and their components, in addition to the parameters
of nodulation in Rhizobium inoculated treatments. There were not significant differences for
all variables. However, the highest yield records were obtained in the treatments with biofertilizers
T7, T3, T4 with 2031,1948 and 1946 kg/ha respectively and the control yielded 1604 kg/ha.
