RESPONSES OF SULFUR AND PHOSPHORUS DOSES ON THE YIELD AND QUALITY OF FENUGREEK (Trigonella foenum-graecum L.)

Abstract

This study was conducted to determine the effects of sulfur and phosphorus doses on the yield and quality of fenugreek in Siirt, Turkey, in the 2016-2017 and 2017-2018 growing seasons. Field trials were designed in a factorial complete block design with three replications at the experimental fields of the Agricultural Faculty of Siirt University. In the study, plant height (cm), first pod height (cm), the number of pods (pod plant(-1)), the number of seeds in the pod (seed pod(-1)), pod length (cm), thousand-seed weight (g), seed yield (kg ha(-1)), protein content (%) and trigonelline content (%) were determined. All of the growth and yield parameters, except for plant height and pod length, were significantly affected by sulfur fertilization. All the parameters were affected by phosphorus fertilization. The highest seed yield (2224 kg ha(-1)) and trigonelline content (1.26%) were obtained under 30 kg S ha(-1) and 90 kg P ha(-1) applications.
