| Abstract | ||
| To test the influence of biostimulants and potassium humate on growth and yield traits of black cumin cultivated on soil obtained from an agricultural station in Al-Shafi'iyah, Diwaniyah Governorate, Iraq, at a depth of 0-30 cm, the experiment was carried out in a randomized complete block design (RCBD) as a two-factor factorial experiment with three replications. The pots were irrigated just one time be-fore sowing. Planting was done with local black cumin seeds received from an agricultural office in Sulaymaniyah Governorate on October 16, 2022. Seeds were 10 in number, and 5 were thinned after germination. The first factor of the experiment was biostimulants applied at three levels denoted by (A0, A1, and A2), and the second was potassium humate supplied at four levels, denoted by (HK0, HK1, HK2, and HK3). Results of the experiment are as follows: - Among the studied growth and yield traits (plant height, number of flowers per plant, number of seeds per capsule, 1000-seed weight, and percentage of oil in the grains), the binary combination of biostimulants and potassium humate gave the best results. The binary combination A2HK2 gave the highest values of these traits with 58.88 cm plant-1, 29.55 flowers plant-1, 97.05 seeds Wallet-1, 75.17 g, and 1.653% in comparison to the control treatment, which gave the lowest values as 32.96 cm plant-1, 13.92 flowers plant-1, 70.85 seeds Wallet-1, 41.08 g, and 0.803%. | ||
