Evaluación de un biofertilizante a base de Chlorella sp y Nostoc sp en Zea mays L. en condiciones de laboratorio.

Abstract

In the present titration work, the effect of a biofertilizer made from the microalgae Chlorella sp and the cyanobacterium Nostoc sp applied to the cultivation of corn (Zea mays L.) was evaluated, with the objective of measuring its effectiveness in both germination. as in the development of seedlings. For the cultivation of microorganisms, specific culture media were used: Basfoliar for Chlorella sp and BG110 for Nostoc sp, with variations in its nitrogen source to determine the medium with the greatest cell growth for its climbing. Subsequently, the best biomass separation method of each species was developed for use in the treatments applied to corn. The results obtained indicated that the treatments with the biofertilizer based on Chlorella sp and Nostoc sp presented the highest average values in plant height, leaf height, number of leaves, main root size and number of total roots, in comparison with chemical control and other treatments. The results agree with previous studies that have demonstrated the benefits of using microalgae as biofertilizers in agricultural crops. The biofertilizer based on Chlorella sp. and Nostoc sp. had a positive effect on the growth and development of corn plants, which could represent a sustainable alternative to conventional chemical fertilizers
