Evaluación del comportamiento agronómico, productivo y nutricional de tres variedades comerciales del forraje guinea (panicum máximum o megathyrsus maximus) en el trópico bajo de la Costa Norte Colombiana.

Abstract

The objective of this research was to evaluate the agronomic, productive and nutritional behavior of three commercial varieties of Guinea grass such as Tanzania, Massai and Mombaza (Panicum maximum or Megathyrsus maximus) in the low tropics of the Colombian North Coast. The study was carried out in the department of Bolívar Municipality of María la Baja jurisdiction of the San José del Playón district on the Villa Eliana farm. presenting physical-chemical properties of clay loam soil, with a tendency to water retention. A completely randomized block design was carried out, taking dataevery 8 days for 12 weeks, these were analyzed in the SPSS version 22 program. Where the following results were obtained, growth T3 61.76 cm average weekly, T2, 44.22 cm weekly average, T1, 60.1 cm weekly average, Stem leaf ratio where T2 presented 40 g of dry matter in leaves and 51g in stems also presented the broadest relationship compared to T1, which had 39 g in leaves and 42 g in stems in the same way T3 presented 40 g in leaves and 38 g in stems. The green forage production obtained per hectare in the Tanzania variety was 392.5 tn / fv / ha and with a protein of 10.3, Massai 32 tn / fv / ha, bp 9.63, T1 405 tn / fv / ha , bp 8.63. There is a significant difference in terms of production and growth between T1, T3 compared to T2. And with a cost per square meter of T1 and T3 of $ 19.16 and T2 of $ 20.83.
