Evaluación de un biocatalizador con tres niveles de fertilización, en la producción de arveja (Pisum sativum) de crecimiento indeterminado var. San Isidro, en la Granja Experimental Docente Querochaca

Abstract

The present work was carried out with the purpose of evaluating the benefit of the application of a biocatalyst with three levels of fertilization in the production of pea var. San Isidro in the Experimental Teaching Farm Querochaca. The experiment was carried out at the Technical University of Ambato, Tungurahua province. Its coordinates according to the global positioning system (GPS) are as follows: 78º35 'longitude west and 1'24' south latitude. It is located at an altitude of 2850msnm. A randomized complete block design with 3x 3 +1 factorial arrangement with three replicates was used. The plant height was measured from 40 to 100 days of the crop, during which no statistical variations were found until 100 days after which we can observe that the D3N1 treatment had the best plant height with an average of 167.8 Cm. The application of a high dose of biocatalyst produced a direct response on the weight of the pod in the pea crop, since better results were obtained when comparing the treatments statistically. In the grain weight variable it was possible to differentiate that in the first harvest the treatments D3N2 and D1N3 had the best average values with 1.47 and 1.40 g respectively, in the second crop was the D2N3 treatment which had the highest weight Of grain with an average of 0.90 grams; While in the third crop the treatments D3N1 and D1N1 with averages of 0.16 and 0.73 g were the highest grain weight. Statistical analyzes for pod length showed that the treatments that received the application of fertilizers and biocatalyst had statistically equal results with values ranging from 6.77 to 5.70 cm; Not so the control that had a shorter sheath length with an average of 4.07 cm. The use of higher levels of fertilization together with higher doses of biocatalyst present in treatments D3N3 and D3N2 increased yields in this crop with values of 8719.8 and 8181.2 kg / ha respectively. The economic analysis of the experiment can be considered that the best economic return was achieved with the treatment D3N3 that has a benefit / cost ratio of 1.53. Key words: biocatalyst, fertilization, yield, biodegradation.
