“…There were trials which exhibited insignificant correlations with grain yield indicating that there is potential to identify genotypes within particular environments that have no tradeoffs between increasing grain yield and nutritive value of straw. These results concur with findings of previous studies reported in faba bean (Alkhtib et al, 2016), pearl millet (Blummel et al, 2010a) and sorghum (Blummel et al, 2010b) and which reported that selection of genotypes to achieve high grain yield did not depress the digestibility and energy content of straw. Most of the trials showed positive and high correlations between maturity type and straw yield as well as maturity type and nutritive value.…”

To explore genetic and environmental variability of food-feed traits in lentil genotypes, straws of 78elite genotypes and 4 checks of early and late maturing lentil types were evaluated for their nutritive value and potential trade-offs of the nutritive parameters with straw yield and grain yield. Further, effects of genotypic and environmental sources on variation in the nutritive value were also determined. Straw nutritive traits were analyzed by a combination of conventional laboratory techniques and Near Infrared Reflectance Spectroscopy. Results from eight trials carried out across 3 different sites in Ethiopia showed highly significant genotypic variation (P<0.05) in grain yield, straw yields and straw nutritive traits. This confirmed the existence of exploitable genetic variation in these traits. Similarly, the relationship between grain yield and straw yield was positive. The correlation between grain yield and nutritive parameters of straw was insignificant or negative. The correlation between maturity types and straw traits was either neutral or negative. Genotype by environment interactions were significant (P<0.05) for straw yield and nutritive traits indicating that variation in the traits is dependent of environment. It is possible to develop genotypes with a combination of food -feed traits from early and late maturing lentil types to address the high demand for grain and livestock fodder in various agro ecological zones in mixed crop-livestock farming systems using appropriate breeding approaches.

“…The nutritive value of lentil straw can be improved by breeding genotypes which have straw with low NDF content. Our results agree with Alkhtib et al (2016) who found out that principle component analysis score can be used to summarize the nutritive value of faba bean straw.…”

“…In mixed crop‐livestock farming systems, enhancement of the crop stover production tends to improve production of milk and meat from livestock in the Tibetan Plateau (Nan et al, ) and similar environments elsewhere in the world (Wamatu, Alemu, et al, ). The significant varietal differences observed among the varieties for grain and stover yields are in agreement with previously findings on common vetch (Larbi et al, ) as well as faba bean ( Vicia faba L.; Alkhtib, Wamatu, Wegi, & Rischkowsky, ) and chickpea ( Cicer arietinum; Wamatu, Mersha, et al, ). The observation of wide ranges in grain and stover yields implies a possibility of enhancing both yields of common vetch through selection (Alkhtib et al, ).…”

“…The existence of significant varietal variation in the relative proportions of the stover fractions is in line with results reported for chickpea (Kafilzadeh & Maleki, ) and faba bean (Alkhtib et al, ). In the current study, the average contribution of leaves (29.6%), pods (35.6%) and stem (34.8%) to the whole stover differed from a previous study on faba bean stover Alkhtib et al () which mainly consisted of stems (mean 70.1%) and pods (mean 23.1%). However, the range of the pod proportion (22.0%–45.6%) in our results was within the range reported for the chickpea (5%–44%) (Kafilzadeh & Maleki, ).…”

This study evaluated the varietal variability and interrelationship of the grain and stover yields, and stover quality characteristics of four common vetch varieties (three improved varieties and one local variety) used on the Tibetan Plateau. Stover quality attributes determined included chemical composition, in vitro true digestibility of dry matter (IVTD) and neutral detergent fibre (dNDF). The improved varieties were superior to the local variety in grain yield, harvest index and potential utility index (PUI). The wide ranges in the proportions of leaf (24.3%–34.6%), pod (22.0%–45.6%) and stem (29.5%–44.7%) fractions were observed. Significant varietal differences (p < .001) were observed for the whole‐stover content of crude protein [CP; 78.1–101 g/kg dry matter (DM)], neutral detergent fibre (aNDF; 520–564 g/kg DM), acid detergent fibre (ADF; 520–564 g/kg DM), IVTD (597–658 g/kg DM) and dNDF (305–384 g/kg aNDF). The leaf fraction had the highest levels of CP, IVTD and dNDF, while the highest contents of aNDF and ADF were observed in the stem fraction. Canonical correlation analysis showed that significant (p < .001) correlations between the quality attributes of whole stover and proportions and quality attributes of stover morphological fractions. Pearson correlation between the grain and stover yield was negative and significant (r = −.295; p = .001), while the correlations between the grain/stover yield and stover quality traits were positive or non‐significant. Ranking of the varieties differed when grain yield, PUI and stover quality scores were investigated. Of the varieties tested, Lanjian No.2 has the best potential for use as a ruminant feed, as indicated by PUI and stover quality.
