The effects of different sowing times on some yield and yield components of coriander (Coriandrum sativum l.)

This research was carried out in 2018 vegetation period in Yozgat Bozok University, Faculty of Agriculture, Artillery Research and Application Field in order to investigate the effects of coriander (Coriandrum sativum L.) sown at different planting times in Yozgat ecological conditions. Two coriander types (Arslan and Gürbüz) were used as material. The research was established with three replications according to the split plot design in randomized blocks. Main parcels varieties, sub-parcels formed different sowing times. The dates are respectively 15 April 2018, 28 April 2018, 15 May 2018. According to the results of the research; plant height, number of branches per plant, number of umbrellas per plant, number of seeds in umbrella, first branch height, thousand seed weight, biological yield, seed yield, stalk yield, harvest index, volatile oil ratio and yield, respectively, the average values 42.18-53.07 cm, 4.34-3.27 pieces, 5.144-6.144 pieces, 17.22-20.31 pieces, 15.26-24.77 cm, 13.79-9.65 g, 79.05-77.78 kg / da, 44.90-42.24 kg / da, 33.10-35.53 kg / da,% 19.00-14.67 0.544-0.644, 24.89-28.36 L / ha
