Öğe The effect of different humic acid fertilization on yield and yield components performances of common millet (Panicum miliaceum L.)(Academic Journals, 2011) Saruhan, Veysel; Kusvuran, Alpaslan; Babat, SevgiOrganic matter is a fundamental in soil, but dynamic component of soils that influences the many chemical, physical and biological properties that regulate soil productivity. Objective of using humic substances in plant is to balance vegetative and reproductive growth as well as to improve herbage and protein yield. This study has been carried out at the experimental area of the Field Crops Department of Dicle University, Agricultural Faculty in 2005 to 2006, to determine the effects of different humic acid treatments (Control, Soil 100%, Seeds 100%, Leafs 100%, Soil 50%+Seeds 50%, Soil 50%+ Leafs 50%, Seeds 50%+ Leafs 50% and Seeds 33%+Soil 33%+Leafs 33% fertilizations) on yield and yield performances of common millet. According to results of the study, humic acid treatments raised the yield and yield components, and this raising was found to be significant statistically. The highest value for plant heights, bunch lengths, grain yields, 1000 grain weight, crude protein concentrations and grain number per bunch were obtained from leafs (100%) fertilizations and the highest hectoliter weight was obtained from seeds (100%) fertilizations.Öğe The effect of different replications of humic acid fertilization on yield performances of common vetch (Vicia sativa L.)(Academic Journals, 2011) Saruhan, Veysel; Kusvuran, Alpaslan; Kokten, KaganThis study was conducted in a randomized complete block design with three replications in Diyarbakir, Turkey, in 2003 to 2004 and 2004 to 2005 growing seasons, in order to determine the effects of different humic acid treatments (control, soil 100%, seeds 100%, leaves 100%, soil 50% + seeds 50%, soil 50% + leaves 50%, seeds 50% + leaves 50% and seeds 33% + soil 33% + leaves 33% fertilizations) on herbage and crude protein concentration of common vetch. According to the results of this study, humic acid treatments increased the yields, and this increase was found to be significant as well as statistical. According to the two-year research, the highest value for green herbage yield (15180 kg ha(-1)), dry herbage yield (3045 kg ha(-1)) and plant height (61 cm) was obtained from soil 100% fertilizations, while the highest crude protein concentration (13.43%) was obtained from seeds 33% + soil 33% + leaves 33% fertilizations.Öğe EFFECTS OF SEWAGE SLUDGE USED AS FERTILIZER ON THE YIELD AND CHEMICAL CONTENTS OF LUCERNE (Medicago sativa L.) AND SOIL(Parlar Scientific Publications (P S P), 2015) Kusvuran, Alpaslan; Saruhan, Veysel; Aydin, Isil; Kokten, KaganThis study was conducted to determine the effects of sewage sludge (SS) used as fertilizer at different concentrations (control, 20 kg ha(-1) nitrogen (N), 30, 60 and 90 ton ha(-4) SS, 20 kg ha(-1) N + 30 ton ha(-1) SS, 20 kg ha(-1) N + 60 ton ha(-1) SS and 20 kg ha(-1) N + 90 ton ha(-1) SS) on lucerne yields and chemical features. For this purpose, an increasing level of SS was applied to the soil samples. The residuals of some heavy metal (Hg, Cr, Fe, Ni, Zn, Mn, Pb, Cu, Co, and Se) and macro element (K, Ca, Na, Mg, C, and S) concentrations were measured in the plants and soils. According to the results of this study, SS, when applied to soil in increasing amounts, raised the mineral matter contents of the plants, which favorably affected plant growth. Consequently, it affected the herbage yield, increasing the yield in parallel with the increasing SS concentrations. Applying N with the SS positively influenced the heavy metal contents of the lucerne and residue in the soil. Additionally, the heavy metal contents were found at below critical levels in both the soil and plants. Therefore, SS application as fertilizer used in appropriate concentrations did not pollute the soil very much, but did lead to an increase in plant products.Öğe Fatty Acid Compositions of the Seeds of Some Trifolium Species(Springer, 2017) Saruhan, Veysel; Kokten, Kagan; Kusvuran, Alpaslan; Inci, Hakan; Das, Aydin; Yilmaz, H.
