STRUCTURE, MORPHOGENESIS AND CAPIM PRODUCTION MG-5 SUBMITTED TO FOLIAR FERTILIZATION
Foliar fertilization; morphogenesis
In view of the clear knowledge gaps that hinder the development of strategies for the use of foliar fertilization, mainly in forage plants, the objective of this work was to evaluate the effects of the application of this type of fertilizer at different moments of the initial development of grass plants MG-5. The experiment was conducted in a greenhouse of UNIFESSPA, Marabá municipality, in a completely randomized design, where the dose equivalent to 2 l / ha of fertilizer was applied at five different times, with plants presenting 3, 4, 5 and 6 leaves expanded by plant on average, besides the control (without application), being these the treatments, with 06 repetitions each, totaling 30 experimental units. The following variables were analyzed: Leaf appearance rate (TApf), Filochron (FILO), Leaf elongation rate (Talf), Stretch elongation rate (Talc), Final leaf length (CFF), Number of live leaves (NFV) , Leaf senescence rate (Tsf), number of tillers (Nperf), accumulation of dry matter (DM) and leaf: stem ratio (Rfc). From the statistical analysis of the data, no significant difference between the treatments was found for any of the variables studied. Such results can probably be explained by the low dose indicated by the manufacturer for use. Another fact that may have influenced the nutritional status of the soil used as a substrate, may have been to provide all the nutrient requirement of both treatments. It is concluded that at the dose of 2 l / ha there is no effect of the foliar fertilizer used for the forage studied.
