The purpose of the study was to determine the effects of microbial fertilizers applied in different growth stages on oil content, fatty acid composition and oil quality of peanut (Arachis hypogaea L.). The study was conducted in Osmaniye/Turkey in 2019 and 2020 according to RCBD arranged in split-plots design with 3 replications. The highest oil contents were observed in 150 cc da-1 (53.07%) and beginning bloom + full bloom (53.95%) treatments in studied years. For total unsaturated fatty acid compositions, the highest values were obtained in full bloom (79.49%) and 100 cc da-1 (79.99%) treatments. The highest O/L ratio were observed in full bloom and 100 cc da-1 treatments as 1.72 and 1.68, respectively according to mean of 2-year values. Similar results were seen in IV, and these treatments came forefront with the values 93.83 and 94.52, respectively. As a results of the study, it was concluded that (i) microbial fertilizers had the positive effects on oil content and quality parameters of peanut, (ii) the treatment 100 cc da-1 applied in full bloom may be the optimum selection.","PeriodicalId":23385,"journal":{"name":"Turkish Journal of Field Crops","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46765095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment in a split-plot design, N fertilization as the main plot, the seed inoculation as the sub-plot was set up in three replicates.

Besides, the rate and application time of P fertilization gained more importance just after the researchers found out it is more effective than N-fertilizing for alfalfa cultivation. This study aimed to determine the effects of different irrigation managements (seasonal deficit, intervals of 5, 7, and 9 days), phosphorus application season (autumn and spring), and the rate of P fertilizer (0, 30, 60, 90 kg ha-1) on the yield and forage quality of alfalfa. The experiment was conducted in the 2019-2020 years, which was the 3rd and the 4th years of alfalfa respectively, under semi-arid Mediterranean conditions. The stand height and fiber content (NDF) were higher in the autumn application. However, forage contained more nitrogen in the spring application. A higher amount of water (800 mm) with higher irrigation frequency (5 days – I5d) caused a reduction in yield due to water excess. The yield was the highest (21.34 t ha-1) and the forage quality was better in 448 mm water application with 9 days intervals (I9d). Seasonal deficit water management caused a significant loss in yield and quality. Nevertheless, 18.04 t ha-1 dry matter yield with 24.05 % CP content was recorded at seasonal deficit water management. P fertilization increased the yield and forage quality. The yield was the highest (20.23 t ha-1) at the rate of 90 kg ha-1 P fertilizer, but yield and forage quality characteristics were similar between 30, 60, and 90 kg ha-1 P. The results showed that P fertilization could be done in both autumn and spring at the rate of 30 kg ha-1 and 448 mm water could be applied at 9 days intervals for fulfilling performance under semi-arid Mediterranean conditions. When water resources are very scarce, the seasonal water deficit should be applied, especially in late summer.","PeriodicalId":23385,"journal":{"name":"Turkish Journal of Field Crops","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42245026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
