Evaluación de la producción primaria de una mezcla forrajera con la aplicación de diferentes niveles de humus y una base estándar de nitrógeno

Abstract

In the Chimborazo province, Canton Chambo, Asactus Neighborhood, San Pedro de Llucud assessed the use of 6, 8, 10 and 12 Tn / ha of humus over a standard basis of nitrogen (250 kg/ha) compared to control treatment in the primary forage production of a mixture of Lolium perenne (Rye grass), Medicago sativa (Alfalfa) and Trifolium repens (white clover) through a randomized complete block design with two replications. The experimental data were subjected to analysis of variance and mean separation according to Tukey. The results between treatments show significant differences statistical (P < 0.01) by applying 10Tn/ha of Humus (T3), obtaining a plant height of 50.04 cm (first cut) and 52,96cm (second cut); besides it noticed in a shorterperiod of time the pre-flowering occurrence which means 27.50 days in the first cut and 30.00 days in the second; on the other hand it noticed the forage production 25.92 and 23.83 Tn/ FV/ha/cut in the first and second cut respectively; Taking into account that the production of dry matter was of 5.12 (first cut) and 5.03 Tn/Ms/ha/ cut (second cut). Finally it got a benefit /cost of 1.76 and 1.48 in the first and second cut. Therefore it is recommended to use 10 Tn /ha of humus over a standard basis of nitrogen into fertilization process on forage mixture due to better production and economic responses are achieved.
