Incidence of the shading, bioregulators and biostimulant on the growth and yield of Mombaza grass (Panicum maximum Jacq.)

Shading (S), bioregulators (BR) and biostimulants (BS) techniques are alternatives that promote sprouting production of grass. The objective was to evaluate the effect S, BR BSt on growth yield Mombaza grass in Ecuador. A complete randomized block design, with split plot arrangement three replications, used, main represented by condition S (S1: full solar exposure, S2: shade trees) secondary one BS application (A0: control; A1: minimum doses BR, 250 mL.ha-1 Cytokin + 10 g.ha-1 New Gibb %; A2: maximum 500 20 A3: commercial dose Algamar, seaweed, 750 g.ha-1). Three cuts were made, 35 days after staring experiment; each one, tiller height (TH), number tillersm-2 (NTM) stemstiller-1 (NST), dry matter (DMY) evaluated. It is found effects (P<0.05) four variables cut; TH 1, period least precipitation. concluded cultivated S1 increased DMY 2 3 (0.180, 0.300 y 0.398 kg.m-2). NTM stimulated S2 BR.
