Results of correlation analysis indicated that seed yield in narbon bean (Vicia narbonensis L.) was correlated positively with harvest index, biological yield, weight, number of seed and number of pod per plant and also plant height and number of plant per m 2 . Path coefficient analyses revealed that harvest index and biological yield had higher positive direct effects on seed yield than other variables. Stepwise multiple regression analysis showed that 95.1% of total variation in seed yield could be explained by the variation in harvest index, biological yield and plant height. Results suggest that harvest index and biological yield are primary selection criteria for improving seed yield in narbon bean.
The objective of this research was to determine the forage yield, quality and physiological properties of mixtures of common vetch (Vicia sativa L.) with triticale (×Triticosecale Wittmack) and annual ryegrass (Lolium moltiflorum) grown as intermediate winter crop system under the conditions of Southern Marmara Region. Forage yield, light interception, leaf area index, crude protein content, crude protein yield, ADF and NDF contents were measured. The highest forage yield (15.21 t ha-1) was obtained from 50% common vetch + 50% triticale mixture which was followed by 75% common vetch + 25% triticale, 25% common vetch + 75% triticale, 25% common vetch + 75% annual ryegrass mixtures.The results of two-year averages indicated that the 75% common vetch + 25 % triticale mixturewas the best one for good quality and higher forage yield, and its suitability wasrecommended for the experimental ecology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
