ABSTRACT
Oat (Avena sativa var. nuda) is of an increasing interest in many parts of the world. This is why plant breeders have developed forms that are morphologically different from the current ones, such as naked, dwarf or with an increased 1000-grain-weight. In three experiments conducted at two sites, the influence of phosphorus (P) and potassium (K) fertilizers, spray application of urea and spray application of plant growth regulators (PGRs) Promalin (gibberellins + cytokinin) and Moddus (cimectacarps) on the yield and morphological traits of different oat forms were studied. At a better site, only genotype statistically influenced oat grain yield. At a poorer site, apart from genotype there were statistically significant responses to P and K fertilizers and to the application of Moddus (especially in the experiment with a dwarf cultivar). The internode and panicle length were modified mostly by cimectacarps, which shortened specific internodes, but not the panicle. The PGR Promalin had no significant effect on oat stem morphology.
