Abstract

GIL RAMIREZ, Luis Arturo et al. Influence of the concentrations of “biol” on the growth and development of Medicago sativa (Fabaceae) “alfalfa”. Arnaldoa [online]. 2022, vol.29, n.1, pp.149-162. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.291.29109.

Currently the inappropriate use of agrochemicals has generated negative impacts in the agricultural and environmental sector, due to this the influence of the different concentrations of the “biol” in the growth and development of Medicago sativa (Fabaceae) “alfalfa” was evaluated for which five treatments made up of five 1m2 patches of Medicago sativa “alfalfa”; they were watered every four days with 100% “biol”; 50.0%; 25.0%; 12.5% and with drinking water respectively for four months. The “biol” used was produced at the Applied Biochemistry Experimental Station and the seeds of Medicago sativa “alfalfa” were acquired from the commercial company Suppliers Agropecuarios Foll Perú S.A.C. The results show the presence of N, P, and K at concentrations of 290.0 mgL-1; 17.78 mgL-1; 111.7 mgL-1 respectively; in addition to other micronutrients; likewise, the microbiological analysis reported the absence of total and fecal coliform microorganisms. It was observed that the length of the stem of the plants treated with “biol” at 50.0% with respect to the other treatments, presented a significant difference at P <0.05, however; the number of leaves of the treatments with “biol” at 25.0%, 50.0% and 100% did not show significant difference according to the “t” test, therefore it was concluded that the “biol” did favor the growth and development of Medicago sativa “alfalfa”. The importance of this research lies in the positive effects that the “biol” provides on the proper growth and development of the species to be cultivated and as an environmentally friendly product.

Keywords : Growth; Developing; Medicago sativa “alfalfa”; “biol”.
