- Abstract
Objective: To determine the dynamics of growth in Guinea grass (Megathyrsus maximus (Jacq.) B.K. Simon & S.W.L. Jacobs) cv. Mombasa in response to the application of different doses of chemical fertilization with nitrogen (N), phosphorus (P) and potassium (K) in humid tropical climate conditions. Design/methodology/approach: The experiment was done in Loma Bonita, Oaxaca, Mexico. A plot of Guinea grass was established. Previously, a cut of uniform was done 15 cm above of soil level. Fertilizer treatments were applied based on chemical fertilization with N, P and K. The treatments were: T1=00-00-00, T2=100-00-00, T3=140-20-00, T4=180-40-20, T5=200-00-00, T6=240-40-20, T7=260-60-40, T8=300-00-00 of N:P:K. The response variables were: plant height (cm), dry matter accumulation (kg ha-) and Chlorophyll content using the Chlorophyll meter SPAD-502 of MinoltaMR. Analysis of variance and mean comparison by Tukey (P≥0.05) was realized. Results: The results suggest that fertilization treatments with the highest contents in N, P and K favored the height of plant, the content of Chlorophyll in leaves and the accumulation of dry matter per hectare. Limitations on study/implications: Applying fertilizer is a good alternative way to improve the growth and performance of Guinea grass. Nevertheless, a major number of environmental conditions and annual periods of investigation are required for the obtained results in different livestock zones. Findings/conclusions: The major plant eight was find used the fertilization 140-20-00, the chlorophyll content is high when the formula 260-60-40 is used. Dry matter is better if high doses of N (300-00-00) are used in Guinea grass.
