Pathogenicity and anastomosis groups of seven Rhizoctonia-like isolates obtained from infected pistachio (Pistacia vera L.) seedlings were determined, in the central district of Siirt province at Southeast Anatolia Region in Turkey. Browning on the crown root of the collected saplings and drying of plants were observed. In the pathogenicity test, the most virulent isolate was Rs2 with a disease severity of 93.75%. The anastomosis group of this isolate, which caused the saplings to dry completely was determined as Rhizoctonia solani AG-4. The moderately virulent Rs3 and Rs1 isolates were determined as the binucleate AG-F group. These two isolates caused yellowing of the seedling leaves and browning of the roots, however, the plants did not die and preserved their vitality to a certain extent. The R9 and R14 isolates identified as anastomosis group AG-F did not cause any symptoms on inoculated plants and on the negative control. The Rs7 and Rs10 isolates were identified as the anastomosis group AG-4 and were determined to be pathogenic in saplings. The results of this study are the first record for the virulence and anastomosis groups of Rhizoctonia species that cause root and crown root diseases in Siirt pistachio.
在土耳其东南安纳托利亚地区锡尔特省中部地区，从受感染的开心果(Pistacia vera L.)幼苗中分离得到7株根瘤菌样分离株，对其致病性和吻合群进行了测定。采集的树苗冠根发生褐变，植株干燥。致病性试验中，毒力最强的分离株为Rs2，发病严重程度为93.75%。结果表明，该分离株吻合群为枯枯菌AG-4。中等毒力Rs3和Rs1分离株被确定为双核AG-F组。这两个分离株引起幼苗叶片发黄，根部褐变，但植株没有死亡，并在一定程度上保持了活力。作为吻合组AG-F的R9和R14菌株在接种植株和阴性对照上均未引起任何症状。分离株Rs7和Rs10被鉴定为吻合群AG-4，在树苗中具有致病性。本研究结果首次记录了引起Siirt开心果根和冠根病害的根核菌的毒力和吻合群。

The study determined the prospect of the rice milling cottage industry in Nigeria’s Niger State using cross-sectional data. The data were collected with the aid of a well-structured questionnaire complemented with an interview scheduled from fifty-five (55) active millers chosen through a multi-stage sampling technique. Both descriptive and inferential statistics were used for data analysis. Based on the findings, it can be suggested that the potential of rice milling enterprise in the study area has not been fully explored despite its profitability turnover ratio. The industry is exclusively men enterprise with the majority been low-income earners. Potentials alongside challenges still exist in the rice milling industry as evident by the overwhelming influences of weakness and threat. Millers’ age was observed to be the major inducing factor that increases income inequality among the processors. In lieu of the foregoing, the study advised the millers to adopt a defensive strategy to remain afloat in the industry. In addition, there is a need for capacity building enhancement viz. acquisitions of innovative milling skills by the millers, thus enhancing their managerial efficiency.

This study was carried out in Southeastern Anatolia Region in Turkey between 2017 and 2018 to determine the effect of irrigation skipping in different phenological periods on yield and some physiological properties of corn (Zea mays L.) in second crop conditions. The trial is designed as randomized complete block design with three replications. DKC-6664 hybrid corn variety having classified as moderate maturity in the FAO (650-700) maturity classes were used in the study. Four irrigation skipping periods which are full irrigation treatments (S1, control), irrigation skipping in vegetative growth period (S2), irrigation skipping in pollination period (S3), and irrigation skipping in generative development period (S4) were studied in the research. According to the two-year averages; there were statistically significant differences in hybrid corn variety in terms of investigated characteristics. According to results, grain yield (GY), chlorophyll content (CC, spad), water use efficiency (WUE, mm), crop water stress index (CWSI) and plant water consumption (ETa, mm) were ranged from 12761.5 (S2)-14021.3 (S1) kg ha-1, 39.10 (S4)-44.50 (S1) spad, 1.902 (S1)-2.114 (S3) mm, 0.18 (S3)-0.33 (S4) and 6752 (S3)-7712.0 (S1) mm respectively. Because of drier weather conditions in 2017 compared to 2018, while GY, CC, and WUE parameters decreased, CWSI and ETa parameters increased. In the first year of the trial when dry weather conditions prevailed, the corn variety consumed more water and was more stressed. As a result, yield losses were experienced. There were positive and significant correlations between GY and CC and WUE, and negative and significant correlations between CWSI. The results of the study indicated that irrigation should not be skipped during the entire vegetative period for economical and profitable corn production in semi-arid regions.

Time series data (1966 to 2017) that covered prices of six selected major exporting rice markets in the world were used to determine the integration of rice markets in the world. The collected data were analyzed using both descriptive and inferential statistics. In spite of the long-run price association among the selected six markets, the poor extent of market co-integration made the law of one price (LOP) not to hold i.e. elusive in these markets. Except for Pakistan and China markets, all the remaining markets were quite competitive as they have a high degree of market integration- stable equilibrium that absolved any short-run shocks that generate discontinuity and asymmetric price responses. Pakistan market has a dominant role in price formation of all its contemporary five markets while China market viz. leverage effect (inventory accumulation) is not affected by any local shock that emanated from the five markets. However, the local shock generated from China market is felt by all the selected markets. Furthermore, it was observed that international trade in rice marketing is very useful in Cambodian; USA, and China markets as volatility of their respective current prices was quite persistent. Based on the forecast, it can be inferred that the rice prices of the selected markets will adjust according to supply and demand. Therefore, for the development of a single integrated economic rice market in the world, there is a need to strengthen the linkages and interconnectedness among the major exporting rice markets for faster transmission of price and commodity management for efficient allocation. This can be achieved by enhancing the development of market infrastructure viz. assaying, grading, sorting, standardization, quality assurance, physio-sanitary standardization; use of e-trade and e-commerce, value addition, transportation, and other back-end supply chain.

The aim of this study is to investigate the changes in the number of Angora goat and the amount of mohair obtained from Angora goats, which is one of the Turkey's important gene sources from Central Asia to present day, between 1991-2019 in Turkey via different regression models and to evaluate the results. For this purpose, simple linear, quadratic, cubic, inverse, and logarithmic regression models are used in the study. In order to compare the regression models and determine the most suitable model, the square root of the mean squares (Root Mean Square error-RMSE), the determination coefficient (R2) and the adjusted determination coefficient (AdjR2) were used as comparison criteria. Accordingly, R2 values obtained from simple linear, quadratic, cubic, inverse and logarithmic regression models for the number of Ankara goats shorn are 0.628, 0.99, 0.99, 0.74, 0.90, and RMSE are 135288.27, 25651.46, 18966.20, 114681.75, 71592.54, respectively. For Mohair production, R2 values are 0.61, 0.98, 0.99, 0.75, 0.88, while RMSE is 208.99, 41.84, 32.64, 167.85 and 114.32 respectively. In the number of angora goats, R2 values are 0.70, 0.99, 0.99, 0.73, 0.93, while RMSE is 165264.22, 32818.49, 23410.64, 155421.63 and 79544.79, respectively. In parameter estimates, the most appropriate model according to the highest R2 value and the lowest RMSE value is the cubic regression model. According to the cubic regression model, the estimated number of Angora goats that will be shorn, the number of Angora (mohair) goat, and mohair production in Turkey will be 254307 and 275431 heads, 268321 and 287846 heads, and 439 and 474 tons in 2020 and 2021, respectively. Although in the coming years, an increase in mohair production is projected in Turkey, this is much lower than expected.
本研究的目的是通过不同的回归模型调查1991-2019年土耳其安哥拉山羊数量和从安哥拉山羊获得的马海毛数量的变化，安哥拉山羊是土耳其从中亚至今的重要基因来源之一。为此，研究中使用了简单的线性、二次、三次、逆和对数回归模型。为了比较各回归模型，确定最合适的模型，采用均方根误差(root mean square error-RMSE)的平方根、决定系数(R2)和调整后的决定系数(AdjR2)作为比较标准。由此得出，安卡拉山羊剪毛数的简单线性、二次、三次、逆、对数回归模型的R2值分别为0.628、0.99、0.99、0.74、0.90,RMSE分别为135288.27、25651.46、18966.20、114681.75、71592.54。马海毛产量的R2分别为0.61、0.98、0.99、0.75、0.88,RMSE分别为208.99、41.84、32.64、167.85、114.32。安哥拉山羊数量的R2值分别为0.70、0.99、0.99、0.73、0.93,RMSE分别为165264.22、32818.49、23410.64、155421.63、79544.79。在参数估计中，根据最高R2值和最低RMSE值，最合适的模型是三次回归模型。根据三次回归模型，预计2020年和2021年安哥拉山羊剪毛数量、安哥拉(马海毛)山羊数量和土耳其马海毛产量分别为254307头和275431头、268321头和287846头、439吨和474吨。尽管在未来几年，预计土耳其的马海毛产量将增加，但这远远低于预期。

Accordingly, R2 values obtained from simple linear, quadratic, cubic, inverse and logarithmic regression models for the number of Ankara goats shorn are 0.628, 0.99, 0.99, 0.74, 0.90, and RMSE are 135288.27, 25651.46, 18966.20, 114681.75, 71592.54, respectively. For Mohair production, R2 values are 0.61, 0.98, 0.99, 0.75, 0.88, while RMSE is 208.99, 41.84, 32.64, 167.85 and 114.32 respectively. In the number of angora goats, R2 values are 0.70, 0.99, 0.99, 0.73, 0.93, while RMSE is 165264.22, 32818.49, 23410.64, 155421.63 and 79544.79, respectively. In parameter estimates, the most appropriate model according to the highest R2 value and the lowest RMSE value is the cubic regression model. According to the cubic regression model, the estimated number of Angora goats that will be shorn, the number of Angora (mohair) goat, and mohair production in Turkey will be 254307 and 275431 heads, 268321 and 287846 heads, and 439 and 474 tons in 2020 and 2021, respectively. Although in the coming years, an increase in mohair production is projected in Turkey, this is much lower than expected.","PeriodicalId":32452,"journal":{"name":"Turkiye Tarimsal Arastirmalar Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67793427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
: In this study, it was aimed to determine the reactions and host states of different mung bean ( Vigna radiata Wilczek) genotypes, collected from different regions of Turkey, with Meloidogyne incognita race 2. For thi s purpose, 14 different mung bean genotypes and one registered variety were used in the study. The evaluation process was made according to 1- 9 root gall scale and the egg package production rate scale, and resistance index was calculated. As a result of t he study, a high level of resistance in 1 genotype, 1 moderate resistance, 2 intermediate hosts, 2 very susceptible, 5 medium susceptible, and 4 susceptible reactions were detected against M. incognita race 2. In the genotype named 50 N 01 with high resist ance, the gall index was 1.4, the egg mass production rate was 1.8, and the resistance index was 6.4, while the gall index was 3.4, the egg mass production rate was 4.4 and the resistance index was 31.4 in the genotype named 30 Ç 01. According to the study results, the genotypes 30 Ç 01 and 50 N 01 could be used as a parent in hybridization studies to develop resistant varieties against M. incognita .
