THE EFFECTS OF VERMICOMPOST DOSES ON YIELD AND SOME QUALITY CHARACTERISTICS ON BUCKWHEAT (Fagopyrum esculentum Moench.) GROWN AS SECOND CROP

Abstract

This research has been carried out on the effects of some buckwheat (Fagopyrum esculentum Moench.) varieties in Siirt conditions on yield and quality of vermicompost 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 vermicompost doses were applied to sub-parcels. The study was conducted with the Aktaş and Güneş varieties. Five different doses of vermicompost, 0, 750, 1500, 2250 and 3000 kg ha-1 were applied. In the study, plant height (cm), stem diameter (mm), number of inflorescence (number plant-1), biological yield (kg ha-1), seed yield (kg ha-1), 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-1. In addition, biological yield of 1847.0-4523.0 kg ha-1, seed yield values of 510.0- 1350.0 kg ha-1, 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-1 optimum vermicompost doses.
