Abstract

A trial was conducted at Jhansi during rabi of 2012-13 to study the weed dynamics in six oat genotypes for screening of strong competitive genotypes and major associated weed flora in oat. Amongst the six oat genotypes (JHO-822, JHO-851, JHO-99-1, JHO-99-2, JHO-2000-4 and Kent) used in study, JHO-99-2 was found strong competitor due to early vigorous growth, higher plant height and drooping leaf habit and recorded lowest weed population (97) and weed intensity (21%) and highest green fodder yield (33.18 t/ha). JHO-851 proved poor competitor and recorded highest weed population (248). Melilotus alba, Rumex dentatus and Chenopodium album were found major weeds associated with fodder oat. Therefore, JHO-99-2 can be recommended as a fodder variety in Bundelkhand region as it was found a strong crop-weed competitor and produced highest green fodder yield.
