“…The group comparison of the chemical treatments versus the biological treatments did not reveal a statistically significant difference. The experimental results of Gul and Kara (2015) indicated the non-significant effect of various levels of nitrogen fertilizer on sunflower oil yield, which is consistent with the results of the present study. Namvar et al (2012) reported that the sunflower seed oil yield increased with the increase of nitrogen application and the biofertilizers increased the seed oil yield by 10.84% compared to the control treatment.…”

The present study was conducted to investigate and compare the effect of applying various levels of chemical fertilizers and bioinoculants on the growth and yield of sunflower during the 2017-2018 crop year in Hamedan, Iran. This study was executed as two factorial experiments, as a randomized complete block design in three repetitions. Chemical fertilizers containing nitrogen (N) and phosphorus (P) were used in the first experiment, and nitrogen-fixing (NI) and phosphate-solubilizing (BI) bioinoculants were used in the second experiment. The experimental treatments included applying a urea fertilizer (N 0 =0, N 1 =45, N 2 =90 kg pure nitrogen/ha) and a triple superphosphate (P 0 =0, P 1 =40, P 2 =80 kg pure phosphorus/ha), as well as a nitroxin biofertilizer (NI 0 =0, NI 1 =0.5, NI 2 =1 L/ha) and a biophosphorus (BI 0 =0, BI 1 =0.5, BI 2 =1 L/ha). The results indicated that the highest levels of leaf dry weight, number of seeds per head, head diameter, head weight, seed yield, and the plant's biological yield were obtained for the chemical treatment (N 2 P 2 ) and biological treatment of (NI 2 BI 2 ). Group comparisons between the chemical and biological treatments did not show a significant difference for any of the studied characteristics, therefore, the results of this study conclude that the investigated levels of bioinoculants could be appropriate alternatives to chemical fertilizers.

“…Diğer verim komponentleri arasında önemli bir farklılık olmadığı görülmektedir. [22], araştırma sonucunda, yaş sap verimi ile olgunlaşma süresi arasında (0.824**) ve yaş sap verimi ile kuru sap verimi arasında (0.936**) pozitif yönde ilişki olduğunu tespit etmişlerdir. Araştırmacıların bulmuş olduğu yaş sap verimi ve kuru sap verimi arasındaki pozitif ilişki ile bizim bulmuş olduğumuz sonuçlar ile paralellik gösterirken, yaş sap verimi ile olgunlaşma süresi arasında zıt yönde ilişki bulunmuştur.…”

Özet: Bu çalışma Bayburt Üniversitesine ait deneme arazisinde farklı dozlarda vermikompost (0, 100, 200, 300 ve 400 kg/da) uygulamalarında yağlık ayçiçeği çeşitlerinin (Pioneer 64LC108 ve Pioneer 64LE119) fenolojik ve morfolojik özelliklerini belirlemek amacı ile 2018 yılında yapılmıştır. Araştırma Tesadüf Blokları Deneme Deseni' ne göre üç tekerrürlü olarak yapılmış olup, çalışmada çıkış, tabla olum, çiçeklenme ve olgunlaşma süresi (gün), yaprak sayısı (adet), yaş ve kuru sap verimi (kg/da), yaş dolu, yaş boş ve kuru tabla verimi (kg/da) incelenmiştir. Denemede çıkış, tabla olum, çiçeklenme ve olgunlaşma süresi, yaprak sayısı ve yaş tabla verimi Pioneer64LE119 çeşidinde fazla olurken, yaprak sayısı, yaş ve kuru sap verimi, yaş dolu, yaş boş ve kuru tabla verimi ise Pioneer64LE119 çeşidinden elde edilmiştir. Vermikompost dozlarınızda dekara 200 kg uygulandığında en fazla çıkış, tabla olum, olgunlaşma süresi ve kuru sap verimi elde edilirken, dekara 300 kg vermikompost dozunda ise en fazla yaprak sayısı, yaş sap verimi ve çiçeklenme süresi elde edilmiştir. Sonuç olarak; sap verimi değerleri dikkate alındığında 300 kg'lık vermikompost dozu ve Pioneer 64LC108 çeşidi önerilebileceği kanaatine varılmıştır. Abstract:This study was carried out in 2018 in order to determine the phenological and morphological properties of oil sunflower varieties (Pioneer 64LC108 and Pioneer 64LE119) in different doses of vermicompost (0, 100, 200, 300 and 400 kg da -1 ) in the trial area of Bayburt University. The study was carried out with three replications according to the Randomized Blocks Trial Design. In the study, the output, table burn, flowering and ripening time (days), number of leaves (pieces), age and dry stalk yield (kg da -1 ), age full, wet age and dry tray yield (kg da -1 ) were investigated. In the experiment, the output of the plate, flowering and ripening time, number of leaves and age table yield was higher in Pioneer64LE119 variety, while the number of leaves, age and dry stalk yield, age filled, wet and dry table yield were obtained from Pioneer64LE119 variety. When dosing 200 mg per hectare in your vermicompost doses, the most output, tabula, ripening time and dry stalk yield were obtained, while the maximum number of leaves, age stalk yield and flowering time were obtained at 300 kg vermicompost dose per decare. As a result; Considering the shelf yield data, 300 kg of vermicompost dose and Pioneer 64LC108 variant were suggested.

Among biotic and abiotic factors, imbalanced plant nutrition is more indispensable for low sunflower productivity. To assess the interaction behavior of nitrogen with boron on sunflower growth, yield and its oil quality in alkaline-calcareous soils, a field experiment was conducted for two consecutive growing seasons of 2011 and 2012. Sunflower hybrid (Helianthus annuus 'Hysun-33') was grown on sandy clay loam soil that was amended with diverse boron rates of 0, 2, 4, and 6 kg ha -1 under variable nitrogen levels of 50% RN, 75% RN, and 100% RN 'recommended nitrogen'. Extended duration of phenophases like 50% inflorescence emergence, 50% flowering and 50% maturity stages of sunflower was observed with nitrogen and boron application. Plant height, stem and head diameters were increased significantly through individual use of nitrogen and boron nutrients. Concerning sunflower yield and yield related attributes as number of achenes/head, 1000-achene weight and achene yield were significantly improved with 2.0 kg ha -1 boron rate with 100% RN. Application of nitrogen and boron considerably declined the achene oil contents. Achene protein contents were found maximum with boron rate of 2.0 kg ha -1 under 100% RN nutrition. Significant decline in stearic acid and oleic acid contents while considerable increase in palmitic acid and linoleic acid contents was recorded by individual use of nitrogen and boron supplements. However, boron application in combination with nitrogen could play a vital role to improve the productivity and economic performance of sunflower in calcareous soils.
