The effect of leonardite and azot application on the yield and quality characteristics of the sesame plant in double crop conditions

This study was carried out in the field of Cukurova University Faculty of Agriculture Field Crops Research Area in 2018 according to the plot design. Sarısu sesame variety was used as a trial material. Four different doses of leonardite (L0, L5, L7.5 and L10) and four different doses (N2.5, N5, N7.5 and N10) nitrogen fertilizer on sesame plants were investigated. In the sesame plant of different doses of leonardite and nitrogen fertilizer applied in the research, plant height (cm), number of branches (pieces / plant), first branch height (cm), first capsule height (cm), seed yield (kg / da), 1000 seed weight The effects of (g), fat content (%) and protein ratio (%) were investigated. According to the results of statistical analysis of the obtained data, it was determined that leonardite and nitrogen doses were insignificant on the properties studied. As a result of the research; The seed yield values obtained from the applied leonardite and nitrogen doses ranged between 170.5 and 227.9 kg / da. The highest seed yield was obtained from L7.5 N7.5 application. The maximum number of capsules per plant was taken from L0 N7.5 application with 151.9 units / plant. As a result of this study, it was concluded that the application of leonardite in sesame cultivation in the Çukurova region has no effect on the agronomic characteristics, seed yield and quality characteristics of sesame plant.
