To improve sorghum productivity, farmers need high-yielding sorghum cultivars. A field experiment was conducted in the 2020 cropping season to determine the interaction effect of genotypes in Adana and Antalya locations in Turkey. Two lines plus three checks cultivars were evaluated at both locations in Turkey. The analysis of variance showed highly significant (P≤0.01) differences among the genotypes for all traits. The analyzed result indicates that the genotypes gave a higher yield in the Antalya location in terms of forage yield. The lowest forage yield was obtained from Line 2 and Line 1 with 4735.7 and 6212.9 kg da-1 in Adana, while the highest forage yield was recorded from all genotypes in Antalya. Moreover, forage yield and plant stalk ratio were positively and significantly associated with hay yield. The first two principal components (PC) accounted for 86.42% of the total genotypic variation.
This study was carried out to determine the effects of different levels of organic acid-based sodium formate (SF) addition on nutrient contents, fermentation quality, dry matter intake, digestible dry matter, and relative feed value of no-cob sweet corn silages. In the experiment, groups were formed by adding 0 % SF (control group), 1 % SF and 2 % SF to no-cob corn, and the fermentation period continued for 60 days. At the end of the study, it was determined that SF supplement decreased the dry matter, crude protein, crude oil, ADF, NDF, starch, ME, acetic acid, propionic acid, butyric acid, and ethanol contents of corn silages, whereas it increased lactic acid, crude ash, and starch levels. In addition, it was found that the pH values of the experiment silages were statistically decreased with the addition of 1 % SF; dry matter intake, digestible dry matter, and relative feed values were found to increase. At the end of the study, it was concluded that 1 % SF addition could be used because of its positive effect on the fermentation properties and dry matter intake, digestible dry matter, and relative feed values as well as pH lowering and lactic acid-increasing effect of no-cob corn silages.
This study was conducted to investigate possible use of juice-extracted sweet sorghum stalks (bagasse) as a quality roughage source through silage making. A total of 21 different sweet sorghum (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) genotypes supplied from different sources were used as the primary material of the study. Field experiments were conducted in a randomized blocks design with 4 replications on the experimental fields of Eastern Mediterranean Agricultural Research Institute under 2nd crop conditions during the growing seasons of 2016 and 2017 years. Plants were harvested for bioethanol production at milk-dough stage of panicle grains. Plant leaves and panicles were stripped and remaining stalks were extracted through squeezing. Juice-extracted stalks (bagasse) were ensilaged for 60 days and quality traits were analyzed at the end of silage period. As the average of two years, bagasse yields varied between 42.6-113.9 t ha-1, silage DM yields varied between 11.6-40.0 t ha-1. In addition, crude protein (CP) content, acid detergent lignin (ADL), neutral detergent fiber (NDF) and acid detergent fiber (ADF) values varied between 29.79 - 50.84 g/kg DM, between 49.3 - 91.4 g/kg DM, between 525.1-694.8 g/kg DM and between 351.2-486.8 g/kg DM, respectively. It was concluded based on present findings that silages made from juice-extracted stalks of sweet sorghum grown under 2nd crop conditions of Cukurova region could be used as quality roughage source for livestock.
