This study was carried out to determine the effects of different sowing times and harvest stages on the yield and forage quality of buckwheat in Marmara conditions. The experiment was carried out in Bursa Uludag University Agricultural Application and Research Area in 2018 and 2019 years using Gunes variety as plant material. The experiment was established in a split-plot randomized complete blocks design with three replicates. Four different sowing times (15 April, 1 May, 15 May and 1 June) were considered in the main plot and three different harvest stages (flowering, milk, and dough) in the sub-plot. Results showed that higher plant height, stem diameter, and dry matter yield values were obtained from the plants sown on 15 April and harvested during the milk or dough stages. The highest crude protein ratio, crude protein yield and relative feed value, and the lowest acid detergent fiber and neutral detergent fiber values were determined in plants, which were sown early and harvested during flowering. In general, the delayed harvest stage increased the yield of buckwheat but negatively affected the forage quality.

In this study, genetic and environmental variability, broad-sense heritability, genetic advance and correlation coefficients of pod yield, yield components, oil and protein content of ten registered peanut varieties were examined. Year (Y), location (L), year x location interaction (Y x L), genotype (G), genotype x year interaction (G x Y), genotype x location interaction (G x L) and genotype x year x location interaction (G x Y x L) were significant, but G x Y for shelling percentage was not significant. Genotypic and phenotypic variances were highest for pod yield followed by hundred pod weight, whereas all investigated traits of peanut varieties were significantly different. Broad sense heritability estimates ranged from moderate level to high. Heritability values were estimated to be maximum for shelling percentage (95.4%), hundred kernel weight (91.6%), hundred pod weight (88.3%), while moderate for pod number (63.8%), pod weight (60.4%), first quality pod ratio (63.3%), pod yield (63.2%), oil content (52.0%) and protein content (52.5%). High heritability for shelling percentage, hundred kernel weight and hundred pod weight indicated that these characteristics were affected less than the others by the environmental conditions. The magnitudes of genetic advance were observed to be very high (>50%) for hundred pod weight, 100 kernel weight, pod weight and pod yield; moderate (20-50%) for pod number, first quality pod ratio, shelling percentage and low (

Summer asphodel (Asphodelus aestivus Roth.) has an underground storage organ that enables the plant to survive extreme conditions and contains alkaloids that are toxic for the livestock in rangelands. For this reason, the experiment was carried out in the rangeland of Aydin province (Turkey) in order to determine the most effective methods of weed management where there is an increase in summer asphodel (Asphodelus aestivus Roth.) population. In the study, the effects of 8 different control methods (control, mowing, fertilization, paraquat, glyphosate, 2,4-D, 2,4-D + Picloram, removal from the soil) on yield, quality and botanical composition were investigated. Result of the findings in this study shows that the grasses increased more in vegetation. The highest values of hay yield were observed in paraquat and fertilization applications. High values of crude protein yield were found in fertilization and removal from soil applications. The lowest population of summer asphodel (Asphodelus aestivus Roth.) was obtained removal from soil applications. Together with these results, removal from the soil, fertilization, paraquat and glyphosate applications come to the fore. However, due to the high workforce, it is important to choose an application considering the size of the rangeland and the population of the indicator weed species.

The growth of plants promoting rhizobacteria (PGPR) that live actively in plant roots and rhizosphere and support plant growth has gained widespread importance in agriculture. This study was carried out to obtain and identify PGPR isolates from wheat soil and determine their ability and capacity on plant growth and yield. So, PGPR isolates were obtained from soil, and they were identified as Bacillus sp. (B. simplex and B. pumilus) by biochemical tests and MALDI-TOF MS. After the wheat seeds (Flamura-85) were treated PGPR, the field experiment was conducted with inoculated and non-inoculated seeds at the area of the Field Crops Department, Tekirdag Namık Kemal University in 2016-2018. The experiment was arranged in a split-plot design with three replicates for each treatment. In the experiment, some parameters such as plant height (PH), spike length (SL), number of grain per spike (NGPS), grain weight per spike (GWPS), and grain yield (GY) were evaluated and compared between treatments. The study has shown that PGPR treatments support plant growth and significantly increase yield between 9.6% and 29.29%. Especially, W3 and W4 strains (B. simplex) were showed a significant effect on grain yield. According to the results, we can mention that using PGPR promotes wheat growth and lead to increasing yield in the wheat. The use of PGPR can give promising results for sustainable and eco-friendly agricultural practices.

Phosphorus is an important element that affects the generative development, seed and fruit quality of plants. This study was carried out in the ecological conditions of Kahramanmaras province to determine the effects of different phosphorus doses on the vegetation, yield, and quality characteristics of black cumin. The experiment was carried out in the field of “Field Crops Research and Application Department of Kahramanmaras Sutcu Imam University Faculty of Agriculture” in the winter growing seasons of 2017-18 and 2019-20, according to the split plots in randomized blocks as 3 replications. Two Nigella genotypes, one of which is a registered variety (Cameli variety), and five different P doses (0, 3, 6, 9, 12 kg da-1) were used in the study. According to the research findings, while phosphorus doses did not have a significant effect on plant characteristics such as plant height, number of branches, number of capsules, it was determined that it affected the number of seeds in the capsule and seed yield. The highest number of seeds per capsule (128.23 per capsule-1) was obtained from the highest P (12 kg da-1) application, and the highest seed yield (136.04 kg da-1) was obtained from the 6 kg da-1 P application. Significant differences were observed in doses and genotype × dose interaction in terms of quality characteristics.

In order to evaluate the antioxidant activity of wheat in salinity stress conditions, an experiment was conducted with 27 wheat genotypes, grown on two types of soil: solonetz (increased salinity) and chernozem (control). Analysis of DPPH scavenging activity and phenolic content (PC) were performed in different phenophases of wheat (tillering, stem elongation, heading and full maturity). Genotypes showed significantly higher DPPH scavenging activity and PC under salinity stress conditions (6.08 mg trolox equivalents (TE) per mg of dry matter (d.m.) and 7.27 mg gallic acid equivalents (GAE) per mg d.m., on solonetz, and 4.42 mg TE mg-1 d.m., 6.16 mg GAE mg-1 d.m., on chernozem). The highest antioxidant activity and PC under salinity stress was found in growth stage of stem elongation (10.91 mg TE mg-1 d.m. and 10.09 mg GAE mg-1 d.m.), while on chernozem, genotypes had the highest antioxidant activity and PC in the growth stage of heading (6.08 mg TE mg-1 d.m. and 7.74 mg GAE mg-1 d.m.). Highly significant and positive correlations are present between grain yield and parameters of antioxidant activity, in all growth stages of wheat and both agro-ecological conditions. Therefore, it could be possible to select salinity tolerant genotypes in early growth stages.
为了评估小麦在盐度胁迫条件下的抗氧化活性，对27种小麦基因型进行了试验，这些基因型生长在两种类型的土壤上：solonetz（增加盐度）和黑钙土（对照）。分析了小麦不同生育期（分蘖期、茎伸长期、抽穗期和成熟期）对DPPH的清除活性和酚含量。在盐度胁迫条件下，基因型表现出显著更高的DPPH清除活性和PC（在solonetz上，每毫克干物质6.08毫克trolox当量（TE）和每毫克干物7.27毫克没食子酸当量（GAE），在黑钙土上，分别为4.42毫克TE mg-1 d.m和6.16毫克GAE mg-1 d.m.）。在盐度胁迫下，抗氧化活性和PC最高的是茎伸长生长期（10.91 mg TE mg-1 d.m.和10.09 mg GAE mg-1 d.m），而在黑钙土上，基因型的抗氧化活性和PC最高的是抽穗生长期（6.08 mg TE mg-1d.m.和7.74 mg GAE mg-1 d.m.）。在小麦的所有生长阶段和两种农业生态条件下，粮食产量与抗氧化活性参数之间存在高度显著的正相关性。因此，在生长早期选择耐盐基因型是可能的。

In order to determine the performance of some KWS hybrid corn varieties (V1; Kerbanis, V2; Kefieros, V3; Kontigos, V4; Kefrancos, V5; 2572) belonging to different maturity groups, this study was conducted in Çumra ecological conditions between 2019 and 2020. The research was carried out as three repetitions based on the “randomized plots experimental design". When the results obtained in both years of the study were evaluated together, it was observed that the highest thousand grain weight and grain yield values were obtained from the V2 variety. The highest stem diameter values were obtained from the V1 variety, while the highest first ear height values were obtained from the V2 and V4 varieties. While the highest protein ratio values were obtained from V1 and V3 varieties, the highest grain ear ratio values were obtained from V1 varieties. The highest plant height, number of grains per ear, tasseling stage, and grain weight per ear values were obtained from the V5 variety. However, obtaining the highest stalk lodging and grain moisture values from this variety in both research years eliminated other positive characteristics of this variety. When the highest grain yield value and lowest grain moisture and stalk lodging values are evaluated together, it is seen that the V3 variety is in a recommendable for Çumra ecological conditions

In recent years, oat plant especially for hay yield is on demand in Turkey. In this study, 167 oat landraces originated from Turkey were evaluated for germination and some early seedling stage traits and genotyped by 6K SNP Chip assay to detect candidate markers using association mapping analysis. Principal component analysis (PCA) were also performed to determine relationships among investigated traits. The variation in local oat genotypes for germination and other investigated traits was found significant at the 5% significance level, except for germination rate (GR). The values for germination rate was found between 52-76% and 52-100% for germination ratio, while 12.33 to 45 mm for coleoptile length and 8 to 21 mm for radicle length. On the other hand, plumula length varied between 2 to 28.45 mm and 1301.33 to 5494.40 for seed vigor index. In the research, PC1 and PC2 value was found 41.5% and 21.5%, respectively, explaining the 63% of the total variation. Germination rate and germination ratio (GP) were positively and significantly correlated with the other investigated traits. According to the results of the association mapping analysis a total number of 43 candidate markers were observed, 10 candidate markers for germination rate, five candidate markers for germination ratio (GP), five markers for radicle length (RL), eight markers for coleoptile length (CL), seven markers for plumula length (PL) and eight markers for seed vigor index (SVI). These candidate markers identified in this study for germination and early seedling stage traits could be used in future studies.

The most researches in temperate areas has focused mixtures of spring cereals with forage turnip. In this study, forage turnip “FT” with barley “B”, wheat “W” and oat “O” intercropping at different seed rates (100:0%, 75+25%, 50+50%, and 25+75%) were examined for hay yield, protein yield, relative feed value (RFV), condensed tannin, total phenolic, total flavonoid, and mineral contents (K, P, Ca, and Mg) 2019 and 2020 years. The experiment was arranged as a Randomized Complete Block Design with three replications in Bilecik-Turkey. In combined years, the hay yield was ranged between 5.45-10.27 t ha-1. The protein yield was the highest in alone forage turnip (1.43 t ha-1), 75FT+25B% (1.72 t ha-1), 75FT+25O% (1.72 t ha-1), 50FT+50B% (1.49 t ha-1) and 50FT+50O% (1.80 t ha-1). The condensed tannin content was ranged between 1.82-2.83%. The highest RFV was observed in 25FT+75O% (136.29) and 50FT+50O% (125.42) mixtures. As a result, showed that intercropping forage turnip with barley and oat improved the yield and quality of the hay compared to their monocrops in the present study. Accordingly, forage turnip with barley and oat at 75+25% and 50+50% seed rates exhibited the best results regarding forage yield and quality in the Bilecik ecological conditions.
