No-tillage agricultural practices and pre-plant applications in agricultural systems have become quite common in recent years. In this study, the effect of pre-plant applications on plant characteristics and yield in silage maize cultivation under no-tillage conditions was examined. Plants belonging to the legume (common vetch, narbon vetch and fodder pea) and poaceae (barley, triticale and Italian grass ) families were used as pre-plants materials. Within the scope of the study, the values of plant height, green herb yield, dry matter ratio, dry matter yield, leaf/stem ratio, peak tasselling time and core tasselling time were determined. According to the obtained data, it was observed that the yield of maize was higher in the parcels where the legume family plants were used as pre-plants. Among the legumes, common vetch was determined to increase the maize yield higher than other plants. It was noted that the plants included in poaceae family caused a decrease in the maize yield. When the results of the study were evaluated, it was concluded that legume plants should be selected as pre-plant in no-tillage silage maize cultivation, good results were obtained from especially common vetch, and cereals had a negative effect on the plants grown after them.

Medicago ruthenica L. could be used as the crossbreeding material in forage crops to provide rich resistance gene resources based on its strong resistance to adversity stress. This study aimed to identify the authenticity and analyze heterosis of the intraspecific hybrids acquired from two Medicago ruthenica L. materials. The results showed 85 true hybrids in 118 F1 progenies identified by one SSR marker and five SRAP markers. Besides, the SRAP markers (13.89%) indicated higher identification efficiency than SSR markers (7.69%), and the rate of true hybrids in HZ population (100%) was higher than that in ZH population (36.54%). The six agronomic traits varied to different degrees, and their variation coefficients ranged from 18.53% to 45.72% in 13 hybrids of ZH population in 2019 and 2020. Moreover, ZH7 and ZH8 presented excellent agronomic performance, which could be used as candidate materials for further research. The mid-parent heterosis (Hm) of all agronomic traits was between -20.55% and 36.46%, and heterobeltiosis (Hh) showed negative values of 13

Seed yields of 14 soybean genotypes were evaluated in four locations i.e. Adana, Şanlıurfa, Antalya and İzmir under second crop conditions through summer seasons from 2014 to 2016. The study aims to estimate the stability parameters in terms of seed yield of 14 soybean genotypes by using different stability analysis methods across eleven environmental conditions and to study interrelationships among these stability methods. The analysis of variance for seed yield revealed that the genotypes and the environments as well as the genotype x environment interactions (GEI) were statistically significant at P<0.01. Environmental effects were contributed 51.04% to the total sum of squares whereas GEI and genotype effects were 20.8% and 2.59%, respectively. According to most stability methods, BATEM 223, BATEM 306, BATEM 317 and KASM 02 were determined to be stable genotypes. These genotypes demonstrated superior adaptability with high yield performances in many environments. Results of correlation analysis indicated that seed yield was positively and significantly correlated with Di (P<0.01), Si (P<0.05) and TOP (P<0.01) and showed a negative and significant correlation with Pi (P<0.01) and RS (P<0.01). In addition, the coefficient of regression (bi) was positively significant associated with CVi, αi (P<0.01) and Ri (P<0.05).

Mustard grows in many parts of the world thanks to its ability to adapt to different climatic conditions. It has the potential to be an important oilseed plant especially in the east of Turkey. There is scarcely any information available about fertilization in mustard cultivation in Turkey. Nitrogen and phosphorus fertilizers, a good source of nutrients for the soil, have a positive effect on the growth, development, and yield of the plant in case they are applied at the optimum level. This study was carried out in 2015 and 2016 with the purpose of examining the effects of nitrogen and phosphorus fertilization on the yield and agronomic characteristics of mustard. Five doses of nitrogen (0, 50, 100, 150, 200 kg ha) and phosphorus (0, 30, 60, 90, 120 kg ha) were tested. It was found that the nitrogen and phosphorus applications had significant effects on the plant growth, yield, and yield components in both 2015 and 2016. The characteristics examined within the scope of the study were significantly affected by the applications, and the oil content and seed yield increased with the increasing fertilizer doses. The results of the study emphasize the importance of fertilizer applications for the mustard plants grown in semiarid climates. 200 kg ha of nitrogen and 120 kg ha of phosphorus were found to yield better results, and it was observed that the seed yield of mustard could be increased by increasing the doses of nitrogen and

In this study, some common forage pea cultivars (Golyazi, Ozkaynak, Taskent, Tore, and Urunlu) and a population of Ardahan were investigated during 2015 and 2016 years in Eskisehir condition to determine the forage yield and quality parameters. The fresh forage yield of autumn-sown forage pea (24.36 t ha) was higher than the spring-sown plants (13.42 t ha). Golyazi and Urunlu cultivars had lower fresh forage yields (14.63 and 14.81 t ha respectively) than the other genotypes and Ozkaynak, Taskent, Tore (cvs.), and Ardahan (pop.) were statistically ranked in the same group (between 19.92 and 22.52 t ha). The genotypes produced more dry matter in autumn than spring. The crude protein was higher at autumn sowing (21.17%) than the spring sowing (18.36%) and Ozkaynak had the highest value (21.53%) while Ardahan population was the lowest (17.76%). NDF content was higher in the spring season (37.62%) but only the difference between Taskent (37.60%) and Golyazi (34.06%) was significant among the genotypes. Variation in the ADF content was only significant among the genotypes and the difference between Taskent (33.41%) and Golyazi (31.62%) was significant only as similar to NDF. As a result, Ozkaynak, Taskent, Tore cultivars produce more yield with a satisfying quality by sowing in autumn at Eskisehir conditions, and the population of Ardahan has a high potential to develop new cultivars suitable for the region.
本研究在2015年和2016年期间，在埃斯基谢希尔条件下，对一些常见的饲料豌豆品种（Golyazi、Ozkaynak、Taskent、Tore和Urunlu）和Ardahan种群进行了调查，以确定饲料产量和质量参数。秋播饲草豌豆的鲜草产量（24.36t ha）高于春播饲草（13.42 t ha）。Golyazi和Urunlu品种的鲜草产量（分别为14.63和14.81 t ha）低于其他基因型，Ozkaynak、Taskent、Tore（cvs.）和Ardahan（pop.）在统计上属于同一组（19.92至22.52 t ha）。这些基因型在秋季比春季产生更多的干物质。秋播时粗蛋白含量（21.17%）高于春播（18.36%），Ozkaynak最高（21.53%），Ardahan种群最低（17.76%）。春季NDF含量较高（37.62%），但只有Taskent（37.60%）和Golyazi（34.06%）之间的差异显著。ADF含量的变化仅在基因型之间显著，Taskent（33.41%）和Golyazi（31.62%）之间的差异仅与NDF相似。因此，Ozkaynak、Taskent和Tore品种在Eskisehir条件下秋季播种，产量更高，质量令人满意，Ardahan种群开发适合该地区的新品种的潜力很大。

Adjustment of sowing date and nitrogen (N) use help alleviate farmland contradiction under fluctuating climate in Jianghuai region of China. In this study, two wheat varieties were used to study the interactive effect between two sowing dates and two basal to topdressing ratios of N fertilizer, each treatment of eight combinations arranged in Randomized Complete Block Design (RCBD) with three replications was conducted in two consecutive growth seasons of bread wheat. As results of two years of investigation, wheat plants with an excessively delayed sowing date showed a significant reduction in flag leaf angle, flag leaf area, main stem spike length and photosynthesis rate, yet a increased basic seedling number and transpiration rate, which corresponded to a notable loss in thousand kernel weight and grain yield. An increase in the proportion of topdressed N led to an increase in flag leaf angle and leaf area index, and a lower spike number per unit and thousand kernel weight, to indicate a loss of grain yield. These findings suggest that excessively delayed sowing date and high N topdressing ratios severely affected the canopy structure and thousand kernel weight of bread wheat, and subsequently reduced grain yield. Based on membership function analysis, a sowing date of 25 October coupled with the N topdressing ratio of 7:3 (the basal to topdressing ratios of N fertilizer) was the ideal combination to optimize the wheat industry in Jianghuai region of China.

Nigella sativa, also known as black cumin, is one of the medicinal plants, its seeds show a wide therapeutic potential, and they are used as spice in different kind of foods. The effects of different herbicides on yield and some yield components of Cameli Black cumin cultivar under Adana ecological conditions were investigated in this experiment that conducted between 2015-2016, 2016-2017 and 2017-2018 growing seasons in the Research and Application Area of Field Crops Department of Agricultural Faculty of Cukurova University. Three different herbicides were applied in nine different applications. Plant height, number of branches, number of capsules in the plant, seed yield and oil ratio differed according to application periods. The highest seed yield was obtained from the treatment of hand hoeing. Malondialdehyde and proline analysis were performed to detect oxidative stress and it was found that hand hoeing caused less stress in plants compared to other treatments. According to the results of the study, it was concluded that hand hoeing instead of herbicide application for the control of weeds in black cumin is more appropriate for yield and ecological perspective.
