This study was conducted to determine biomass yields and feed quality parameters of 21 different sweet sorghums (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) genotypes grown as the second crop after wheat harvest under Cukurova conditions. Field experiments were conducted at the experimental fields of Dogankent-Adana location of Eastern Mediterranean Agricultural Research Institute in randomized blocks design with 4 replications in the years 2016 and 2017 (June-October). According to the results of the variance analyses of tha data obtained from the experimenst, years, genotypes and year x genotype interactions had significant effects on investigated parameters. Averaged over two years, dry matter yield (DMY), days to 50% flowering, crude protein content, NDF, ADF, and RFV of the genotypes varied between 21.6 and 62.9 t ha-1, 55.0 and 99.1 days, 3.66 and 5.43%, 41.78 and 52.42%, 29.14 and 37.72%, and 111.3 and 148, respectively. It was determined that Ramada, Roma, Topper 76, UNL hybrid-3 and No91 genotypes were identified as late genotypes with DM yields of greater than 51 t ha-1; Ramada, Roma and Topper 76 genotypes had the first places in terms of quality and they were superior than the other standard cultivars and genotypes.

Potato seedlings of various potato genotypes free from the following viruses PVS (potato viruses S), PVX (potato viruses X), PVY (potato viruses Y), PLRV (potato leafroll virus), PVA (potato viruses A) and PMTV (potato mop-top viruses) were obtained via meristem culture and they were increased in vitro. Seedlings were grown in the greenhouse and mini tubers obtained were tested in the seed bed and in the field trials.
 When the results of greenhouse experiment were evaluated: clone Nif-1 was found to be high for single tuber number (3.0). Clone 6/7-1 had high means as compared to the remaining for single tuber weight (5.2 g) and single plant yield (14.5 g). The highest mini tuber number was obtained from Clone 6/7 in seedbed experiment. Also Hermes-1 had higher means for single tuber weight and Clone 122-1 had the higher means for plant yield and plot yield than that of other clones. Clones Atlantic-2; 3 and 1 (5.8 cm) had high tuber width and clone Hermes-1 and 2 (6.6 cm) had the highest means for tuber length in the seedbed trial. Based on the results of field experiment the highest minituber numbers were obtained from Clone 6/7-2 (10.7) and Clone 6/7-2 (10.3). Atlantic-1 (136.5 g) had high mean for tuber weight as compared to other clones. Nif-1 had the highest mean for plant yield as 920.2 g. Clone 122-1 was found to be higher than the other clones for plot yield (5.3 kg). Clones of Atlantic-1; 2 and 3 (5.9 cm) had high tuber width and clones of Juwel-1; 2 and Hermes-2 (6.8 cm) had the highest means for tuber length.

This study conducted between 2016 and 2017 in the Kosk Village of Yakutiye District of Erzurum Province on rangeland sites with 4 different slopes (0-10%, 10-30%, 30-60 and 60% and above). In the research, current favorable forage yield and some forage quality characteristics of rangeland sites with different slope degrees were investigated. It was determined that the forage yield of rangeland sites decreased in steep slope rangeland sites and increased in slightly sloping rangeland sites. It was determined that the effect of different sloping degrees on some forage quality was important. Slightly slope rangeland sites, forages had higher crude protein content, while steep slope rangeland sites had higher ADF and NDF ratio. Also, it was calculated that the Relative Feed Value (RFV) in the rangelands decreased due to the increase in slope. According to the obtained results, it reveals the necessity to practice appropriate management such as the proper intensity of grazing, especially in sloping areas to ensure sustainable rangeland use.

Crosses were made between 4 potato genotypes and the registered variety Nif in 2015. The F1 seeds obtained from these crosses were grown in pots in the greenhouse to obtain potato clones. The clones selected were grown in seedbeds in 2016 and clones with high yield and tuber number were selected. Selected clones were grown in the field and selection was applied for high yield and yield components. The results obtained could be summarized as followings:
 There were significant variation among the clones and some of them had higher yield than that of the control genotypes. The following 20 clones were selected for the regional yield trials: 3, 21, 184, 185, 194, 195, 196, 202, 204 (Agria x Nif); 89, 90 (6/7 Clone x Nif); 205 (Juwel x Nif) and 153, 159, 160, 163, 164, 174, 176, 177 (Bettina x Nif).

This research was carried out to determine the potential of teff as a staple crop for the Mediterranean climate during 2015 and 2016. The effects of four different sowing dates (15 April, 15 May, 15 June and 15 July) on the grain yield and some yield characteristics were investigated. The teff genotype “Dessie” was used as plant material and plant height, thousand-grain weight, harvest index and grain yield were tested. Two-year average results indicated that there were significant differences in mentioned characteristics among the sowing dates. Delayed sowing dates reduced the grain yield. The highest total grain yield, 2780 kg ha-1, was obtained for the teff seeds sown on the 15th April under Mediterranean ecological conditions.

This study was conducted in Bornova experimental fields of Department of Field Crops, Faculty of Agriculture, University of Ege, Turkey during 2015 and 2016, in order to determine the effect of six different cutting intervals (30-, 60-, 90-, 120-, 150- and 180- days) on the forage yield and some quality properties of giant king grass (Pennisetum hybridum). The experimental design was in complete randomized blocks, with three replications. 6 years old, Paraiso cultivar of giant king grass (GKG) was used as crop material. Some characteristics were measured such as dry matter (DM) yield, concentrations of crude protein (CP), NDF and ADF. Results indicated that there were significant effects of cutting intervals on the yields and some silage quality characteristics of GKG, and, metabolisable energy and relative forage values decreased as inter-cutting interval increased. It was recommended that the production of GKG using 60- day intervals were the most successful cutting frequency regarding the forage yield and silage quality to the regions with Mediterranean-type climates under irrigation.

This study was conducted at the University of Cukurova, Faculty of Agriculture research area in 2018 and 2019 in Adana, Turkey. The objective of this study was to determine the effect of plant density on pod yield and some agronomic characteristics of different growth type peanut varieties (Halisbey and NC-7) in main crop growing condition. In this research; five different intra-row spacing (5, 10, 15. 20 and 25 cm) were used in single row planting pattern. The experimental design was a split plot with three replications. Pod number and pod weight per plant, 100 seed weight, shelling percentage, oil and protein content, pod and kernel yield per hectare characteristics of varieties were investigated. As a result; pod number and weight per plant and 100 seed weight values were decreased when the plant density was increased, but shelling percentage, pod and kernel yield and protein percentage values were increased. The oil content was not affected by the plant density. The highest pod yield (6652 kg ha-1 ) was obtained when the seeds planted at 5 cm inter-row spacing (28.5 plants m-2 plant density). The highest pod yield was obtained from Halisbey variety.

The present study was conducted to determine the performance of summer and winter-sown camelina lines in 2013-2014 and 2014-2015 growing seasons. In experiments, 11 camelina genotypes (Vinimik 17, PI304269, CR 476/65, CR 1674/90, Ames 26665, Ames 26667, Ames 26673, Ames 26676, Ames 26680, Ames 26686 and Ames 28372) were used as the plant materials. Plant height, number of pod per plant, number of seeds per pod, thousand-seed weight, seed yield, oil ratio and oil yield values were measured. The differences in investigated traits of the genotypes were found to be significant (p<0.05). Winter sowings had better performance than summer sowings for yield and yield components. Winter-sown camelina plants were harvested at the end of May or at the beginning of June, which means that it is a good pre-plant for camelina. Average seed yields varied between 2.127 – 4.943 ton ha-1 in winter sowings and between 0.582 – 4.609 ton ha-1 in summer sowings; oil ratios varied respectively between 32.1 - 33.4% and between 24.3 - 35.1%. It was concluded based on findings that camelina should be produced as winter-sown with Ames-26686 genotype. Furthermore, Ames-26680, Ames-26686 and Ames 28372 genotypes could also be grown as summer-sown with quite reliable performance levels in years with sufficient spring precipitations.

This experiment was conducted in order to estimate gene action, combining ability and heterotic effects for yield and quality characters by the line x tester analysis, involving 5 lines and 4 testers with 20 crosses in cotton (Gossypium hirsutum L.). The ratio of general and specific ability variance revealed non-additive gene action effects for seed cotton yield, fiber length, fiber strength and ginning percentage and additive gene action for fiber fineness and reflectance degree. Claudia, Gloria and Bali 308 with high general combining ability were combiner parents and could be used for breeding multi-parent combinations. ST-468 x Claudia, Carisma x Carmen, Bali 308 x Gloria and Bali 308 x Claudia were promising combinations for further selection. Heterosis and heterobeltiosis values of most cross combinations for seed cotton yield, fiber strength and ginning percentage were negative direct. It was concluded that due to non-additive gene actions, it is advisable to select individual plants for seed cotton yield, ginning percentage and fiber properties in later generations (F4-F6).

Among cool-season turf grasses tall fescue (Festuca arundinacea Schreb.) exhibits the best adaptation to the Mediterranean Ecologies. Many turf type cultivars of this drought and heat resistant turf grass have been recently released and therefore management practices consequently should be adapted. The purpose of the study was to detect the agronomic and sports field characteristics of some turf type tall fescue and traditional cool season sports turf mixture mowed at different heights in a Mediterranean environment and to determine the most favorable turf grass alternative and mowing regime. The trial was carried out in the experimental fields of Bayindir Vocational School, Izmir (Turkey), using three different turf alternatives (Tall Fescue 100%, Tall Fescue 60% + Perennial Rye Grass 40% mixture and Traditional Cool Season Sports Turf Mixture: Perennial Rye Grass 50%, Creeping Red Fescue 20%, Chewing's Red Fescue 10%, Sheep Fescue 10%, Kentucky Blue Grass 10%) under 12, 22 and 32 mm mowing height regime. Visual turf quality, texture and weed invasion traits were determined and shock absorption and vertical deformation were also measured as playing quality parameters for a sports turf. Turf alternatives of tall fescue except traditional cool season sports turf mixture showed an adaptation to low mowing height which increased shoot density and promoted a finer leaf texture. Shock absorption and vertical deformation traits were significantly affected by mowing heights, highest value being recorded for the lowest mowing heights. Nevertheless, a good sports field quality was determined for the tall fescue and tall fescue + perennial ryegrass plots. The results of the present work showed that tall fescue, if maintained at low mowing height regime, could provide a dense and fine textured turf suitable for sport fields with a high visual turf quality.
