The current study analyses the influence of genotypic selection and urea treatment to improve the nutritive value of lentil straw. Fourteen (14) genotypes, one local and tow released varieties were replicated 4 times in randomised complete block trial in Debre Zeit research centre. Grain and straw yields were recorded and samples of straw were analysed for their nutritive value. Combined straw form local variety plots in the trial was treated with \mbox{4\,\%} urea across 21 days. General linear model was used to analyse the genotypic variability in grain yield, straw yield and straw quality and the effect of urea treatment on the nutritive value of lentil straw. Simple correlations between the grain yield and straw traits were estimated. The results of the study revealed wide genotypic range in grain yield, however, the genotypic rang in straw yield and straw quality traits was narrow. The correlation between the grain and straw yields was positive, weak and significant while the correlations between the grain yield and the straw quality traits were insignificant. Tow improved genotypes yielded grain almost 1.52 times than the local variety, however, their yield of straw, crude protein (CP), metaboilizable energy (ME) and their straw nutritive value were not significantly lesser than the local variety. Urea treatment succeeded in improving CP and ME content and potential intake of dry matter, CP, ME of lentil straw. However, this improvement was slightly higher than the least significant differences between the genotypes. Finally, selecting genotypes of lentil to increase grain yield did not depress straw yield and quality as livestock feed. Treating lentil straw yield of one ha (3.62 t) needs \mbox{144.8\,kg} of urea fertiliser, however, this treatment will not economically improve the nutritive value of lentil straw. On the other hand, considerable increase in grain and straw yields of lentil could be achieved by applying \unitfrac[50]{kg}{ha} of urea fertilisation according to recent studies in the Ethiopian conditions. Thus, in Ethiopia, where lack of nitrogen fertilisation limits lentil production, using urea as fertiliser will be more reasonable to the farmers than using it for treating lentil straw.}
