Effect of Potassium Doses on Agricultural Characteristics of Camelina Sown in Winter and Summer Season

Abstract

This research carried out in Konya ecology, Arslanbey camelina [Camelina sativa (L.) Crantz] genotype which was planted in 2 different times as winter and summer, in the vegetation period of 2020, was determined at 6 different doses (0 kg da-1, 10 kg da-1, 15 kg da-1, 20 kg da-1, 25 kg da-1, 30 kg da-1) potassium sulphate fertilizer was applied to the soil and its effects on some agricultural properties were determined. Field trials of the study were established according to the Random Blocks trial design with 3 replications. As the results of the research in summer plantings, plant height 50.23-54.01 cm, number of branches per plant 5.60-8.80, number of capsules per plant 30.87-58.80, number of seeds per capsule 14.10-17.60, first capsule height 39.55-45.28 cm, seed yield per plant 0.28-1.27 grams, the number of seeds per plant 252.53-1166.13, thousand grain weight 0.78-1.12 grams, grain yield 63.76-77.75 kg da-1, oil rate 22.54%-29.66%, oil yield between 14.05-22.25 kg da-1. Additionally, the values obtained as a result of the winter planting of camelina; plant height 52.04-57.74 cm, number of branches per plant 8.33-11.70, number of capsules per plant 199.80-274.67, number of seeds in capsule 11.50-13.23, height of first capsule 41.01-47.17 cm, grain yield 1.24-1.65 grams per plant, number of seeds per plant 1754.43-2424.00 pieces, thousand grain weight 0.69-0.85 grams, grain yield 80.65-125.93 kg da-1, oil rate 14.47-18.77%, oil yield 11.97-19.74 kg da-1. It can be said that it is essential to carry out long-term different agronomic studies in different locations related to camelina, an important and alternative oil plant.
