Alfalfa is one of the most important crops mainly grown for forage and hay production in the world. Present study was aimed to investigate the green herbage and hay yield as well as some quality parameters such as acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM), crude protein, dry matter contents, organic matter, crude oil and raw fiber of 9 different alfalfa cultivars. This study was conducted during two consecutive years (2015 and 2016) at two locations in Turkey (Sivas -Center and Sivas-Altinoluk). The mean values of ADF, NDF, DDM, crude protein (CP), green forage yield and dry forage yield were 43.73%, 52.69%, 50.70%,19.71%, 59163 kg ha- 1 and 13866 kg ha- 1 respectively. Dry forage yield reflected a positive and highly significant correlation with plant height, number of tillers and fresh forage yield. The varieties called Delta and Azzura performed very well for both locations during the whole period of study and also expressed a great level of winter resistance. Kayseri is a local cultivar in Turkey and it is revealed to be poor in terms of all the studied traits. According to the results of the study, it was concluded that the cultivars, Delta and Azzura, could be successfully grown in the continental climate regions of Turkey, and they could be also used in the breeding program of alfalfa to develop alfalfa varieties with high winter resistance and high yield and quality of forage.

Sunflower (Helianthus annuus L.) having shorter growing season, better cold tolerant and more drought resistant is important alternative silage plant in highlands. But it has poor silage quality. To improve the quality of sunflower silage can be mixed an appropriate amount of corn (Zea mays L.) and alfalfa (Medicago sativa L.). This research was carried out to evaluate quality characteristics of nine silage types: Sunflower, corn and alfalfa silages; plus their some mixtures silages (75% sunflower + 25% corn, 50% sunflower + 50% corn, 25% sunflower + 75% corn, 75% sunflower + 25% alfalfa, 50% sunflower + 50% alfalfa and 25% sunflower + 75% alfalfa); at two harvest stages: Beginning of flowering for sunflower and alfalfa and milk-dough stage for corn (early stage), and end of flowering stage for sunflower and alfalfa, and dough stage for corn (late stage). The experimental design was in a factorial arrangement of randomized complete block with replicated four times. Dry matter content (DM), crude protein content (CP), neutral detergent fiber content (NDF), acid detergent fiber content (ADF), silage pH and physical characteristics (PC) of silages were determined in this study. Mixing of alfalfa in NDF, ADF and CP and corn in DM, pH and PC had positively effect in sunflower silages. Late stage had positively affected DM, PC and pH for silage. Consequently, sunflower silages mixed with corn, with the condition of not being less than 50% at late stage, are recommended for farmers.

Seker, H.; Yolcu, H.; Acikgoz, E.
An irrigated field study was conducted to determine the relative importance and inter-relationships of growth parameters of three dormant alfalfa (Medicago sativa L.) cultivars grown in the highlands of Eastern Anatolia, Turkey, in 2000-2003. The fast-growing cultivar Savas had the greatest dry matter (DM) yield at the final sampling date with the greatest mean crop growth rate. In addition to a greater relative growth rate (RGR), this cultivar had more stem branching and greater leaf area in the canopy, which resulted in greater leaf area index (LAI) and greater leaf area duration. Despite the considerable increase in leaf area ratio (LAR: leaf area per unit shoot DM), the reduction in RGR of all cultivars over time was the result of a large decline in net assimilation rate (NAR) due to increasing specific leaf area (SLA). Intracultivar variation in the RGR of alfalfa is mainly determined by NAR and SLA, and both were significantly higher for Savas than the other two cultivars. The relative importance of NAR and SLA to RGR changed due to increasing self-shading as the LAI of the canopy increased, creating a trade-off between NAR and SLA.
