Résumé partiel
This study was carried out during the two growing summer seasons of 2019 and 2020 at Experimental Farm, Agronomy Department, Faculty of Agriculture, Assiut University. This work aims to evaluate twenty pear millet genotypes of diverse origin under normal irrigated (1 m3/12 m2) and water stress (½ m3/12 m2) for each irrigation (8 m3 and 4 m3/12 m2, respectively) for forage and seed yields and related traits. Strip plot (split block) design with three replications was used. For forage yield experiment, three cuts were taken for each season. At the time of each cut, the plant height, number of tillers/plant, leaves/stems ratio, fresh, dry and protein forage yield/plant as well as chlorophyll content were recorded. In addition, for seed yield experiment, the plants were left flowering and seed production without cutting. At seed maturity stage, the number of panicle/plant, panicle length, panicle thickness, panicle weight/plant, grain yield/plant and 1000-grain weight were recorded. The results were statistically analyzed and the treatment compared by R.L.S.D. test. In addition, correlationcoefficient between pairs of traits were carried out. Also, direct and indirect effects of characters influencing each of dry forage yield plant and seed yield/plant were detected using path-coefficient analysis (Dewey and Lu, 1959).
