Resumen

ROSABAL AYAN, Lissy; MARTINEZ GONZALEZ, Lisbel; REYES GUERRERO, Yanelis  y  NUNEZ VAZQUEZ, Miriam. Preliminary results applications effects Biobras-16 in bean crop (Phaseolus vulgaris L.). cultrop [online]. 2013, vol.34, n.3, pp.71-75. ISSN 0258-5936.

The common bean (Phaseolus vulgaris L.) is fundamental in cubans meals, but 60 000 tons are imported yearly. Our government has been created programs to augment the national production of this legume. Substitution of importations by the production and commercialization of natural products that lead the increment of yield are been created. In this work it is evaluated the effect of the Biobras-16 (BB-16) in the growth and yield of black beans variety Tomeguín 93, spray to seeds or to leaves. Two experiments were performed, at the first, 15 kg of seeds were sprayed with 150 mL of BB-16 (0,5 mg.L-1) and after 24-48 hours the seeds were sown with a control treatment, and at the second it was sprayed the leaves with a total doses of BB-16 equivalent to 20 mg.ha-1 in one time (flowering stage) and two times (plant growth and flowering stages). The result shows that foliar spray effectiveness in two times in the stimulation of the valuables studies: stem length, sheaths length, number of sheaths and grains, except the 100 grains mass average. It was obtained an increase in 37,7 and 61,3 % in the grains mass average per plant, for one and two times, respectively. This result has great importance in the scientist and economic ambits, and for the future possible application of BB-16 in the production.
