Mineral profile in Panicum maximum cv Mombaza and Tanzania pastures at two regrowth ages

Abstract

This research was carried out in the Cattle Line Livestock Program, properties of the Río Suma experimental farm of the agricultural engineering career of the Laica Eloy Alfaro de Manabí University, in the El Carmen canton, Manabí province, located at Km 30 of the Santo Domingo - Chone road, right margin, between the coordinates of 0° 15' S and 79° 26' W. This study aimed to evaluate the effect of two varieties of pastures at two cut-off ages in mineral content. A completely random design with a 2 x 2 factorial arrangement was used. A total of 4 treatments were used, distributed in 12 repetitions. The statistical software INFOSTAT was used to process the information. The factors under study were varieties of pastures (Mombaza and Tanzania) and age of cutting or regrowth (20 and 25 days), and the variables under study Content of Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and Copper (Cu). The Mombasa grass variety reaches a higher content of K and Mg, and the Tanzania grass contains a higher amount of Ca. The cut or regrowth age of 20 days obtains a more significant amount of Cu; at 25 days, it is possible to fix a more significant amount of P, Ca and Mg. The interactions between Mombaza x 25 days and Tanzania x 25 days reached a higher P content, and Tanzania x 25 days fixed a more significant amount of Ca. Keywords: content; minerals; pastures
