Message:
Abstract:
In order to evaluate the yield components and oil percent of hemp plant under different biological fertilizer and saline water and soil، a field experiment was conducted as a factorial experiment in a randomized complete design with three replications in the North East of Esfahan in 2012. The experimental treatments include، three hemp ecotypes of Esfahan، Shiraz and Mashاad as the first factor and fertilizer treatments of urea، nitroxin، super nitro-plus، bio-sulfur، mycorrhizae (Glomus mosseae) and control (without fertilizer) as the second factor، subjected to saline soil irrigation water. The traits of seed numbers per plant، 1000 seeds weight، grain yield، biological yield، harvest index and percent of seed oil were measured. The results showed the maximum grain yield and harvest index were belong to mycorrhizae treatment and the minimum was belong to control. Besides، mycorrhizae showed maximum biological yield and other treatments had not significantly effect. 1000 seeds weight was affected significantly under different fertilizer treatments، but the ecotypes of Mashhad and Shiraz showed maximum (13. 33 gr.) and ecotype of Esfahan produced minimum (7. 8 gr.) 1000 seeds grain. Each 4 fertilizer treatments caused significant promotion of oil percent (29. 2%) compare to control (26. 5%)، but did not observed any significant effect between fertilizer treatments. Ecotype of Esfahan under bio-sulfur and mycorrhizae treatments with average of 800 seeds per plant had maximum and ecotypes of Mashhad and Shiraz had minimum of 76 seeds per plant.
