The effects of organic fertilizer doses on yield and some quality characteristics on buckwheat (Fagopyrum esculentum Moench.) grown as second crop

This research has been carried out on the effects of some buckwheat (Fagopyrum esculentum Moench.) varieties in Siirt conditions on yield and quality of organic fertilizer doses. This study was conducted in 2017 in Siirt University, Faculty of Agriculture. The experiment was carried out in randomized block design with three replications. Two different buckwheat varieties were sown to main parcels and five different organic fertilizer doses were applied to sub-parcels. The study was conducted with the Aktaş and Güneş varieties. Vermicompost (solid worm manure) was used as the source of organic fertilizer. Five different doses of vermicompost, 0, 750, 1500, 2250 and 3000 kg/ha were applied. In the study, plant height (cm), stem diameter (mm), number of inflorescence (number/plant), biological yield (kg / ha), seed yield (kg/ha), thousand seed weight (g), crude protein content (%), routine content (%) are recorded in the experimental. In the study, plant height was 45.3-59.7 cm, stem diameter were 2.93-4.37 mm, number of inflorescences 7.14-19.6 number/plant. In addition, biological yield of 1847.0-4523.0 kg/ha, seed yield values of 510.0- 1350.0 kg/ha, thousand grain weight 18.95-23.77 g, crude protein content 10.33 - 12.08 (%), routine content 1.01 – 1.75 (%) was found. It is suggested that buckwheat plant is suitable as second crop in Siirt province climate and soil conditions and cultivation of 2490 kg/ha optimum organic fertilizer doses.
