Summary: Interest in growing camelina is increasing for animal nutrition and for biofuel. A trial was carried out in a greenhouse with camelina cv. ‘Calena’ cultivated in pots in order to evaluate the effect of residual poultry manure and mineral fertilization after a crop of barley and to determine the grain’s yield and quality. The treatments applied to the first culture of barley were two: poultry manure or mineral fertilizer N-P-K, at rates of 0, 1, 1.5 and 2 (0, 60, 90, 120 nitrogen fertilizing units). The variables analyzed were the following: dry weight of: seed and aerial biomass and 1,000 seeds; percentages of Kjeldhal nitrogen in: seed, and aerial biomass; percentages of: crude protein and oil content. Treatment type and rates were significant. Treatment*rate interaction was significant (P<0.05) for the analyzed variables except for weight of seed and weight of 1,000 seeds. For the laying hen or mineral the highest values in terms of grain weight were obtained with rates 1 and 1.5, with grain yields equivalent of 1,547 and 1,504 kg/ha, respectively. In terms of crude protein grain the highest values were obtained with rate 1.5 for both treatments, with protein yield equivalent of 455.08 and 478.72 kg/ha and in terms of oil content seed the highest values were obtained with rates 1 and 1.5 with oil content yield of 481.27 and 454.06 kg/ha. In general, camelina had a good response to residual poultry manure or mineral fertilizer in yield and quality of grain.
