| Abstract | Through a completely randomized design and five repetitions, the content of macrominerals, microminerals, ash, and nitrates was studied in four varieties of Pennisetum purpureum (King grass, Taiwan 146, Cuba CT-115 and Cuba CT-169). There were significant differences between varieties, for the indicators studied in leaves and stems. The nitrates varied from 0.023 up to 1 07 The stem had the highest values In the macrominerals, phosphorous ranged between 0.08 and 0.21 %, potassium between 0.62 and 3.25 calcium between 0.25 and 0 76 %, magnesium between 0 29 and 0 85 %, and silica between 0 57 and 4 21 %. In all of them, the highest value was always for the leaves In the microminerals, copper varied between 6.03 and 20 09 ppm, and zinc between 17 42 and 38 32 ppm. The steins recorded the highest value, while the leaves had the highest values for manganese andiron It is concluded that there was variability in the varieties of Pennisetum for the minerals under view, as well as between their leaves, steins and seasonal periods These data may be a guide for the efficient management through the correct application of mineral or organic fertilizers or for the calculation of the mineral needs of ruminants New studies are recommended to widen and complement the information obtained |
