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 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.","PeriodicalId":32452,"journal":{"name":"Turkiye Tarimsal Arastirmalar Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67793136","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}

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.","PeriodicalId":32452,"journal":{"name":"Turkiye Tarimsal Arastirmalar Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67793140","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}

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.","PeriodicalId":32452,"journal":{"name":"Turkiye Tarimsal Arastirmalar Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67793730","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}

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.","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}
