Advantage of Faba Bean (Vicia faba L.) and Cumin (Cuminum cyminum L.) Intercropping under Organic, Biological and Chemical Fertilizer Treatments
Abstract
Abstract The effect of chemical and biological fertilizer treatments on intercropping of faba bean (Vicia faba L.) and cumin (Cuminum cyminum L.) evaluated in factorial experiment based on randomized complete block design with 15 treatments and three replications at the Research Farm of the Faculty of Agriculture, University of Tabriz in 2014. The first factor was including five cropping systems including monoculture of faba bean, monoculture of cumin; three replacement intercropping patterns including row intercropping of faba bean with cumin (1 row faba bean-1 row cumin); strip intercropping as 2 rows faba bean-2 row cumin and 4 rows faba bean-4 rows cumin. The second factor was three levels of fertilizers including 100% chemical fertilizer (50 kg.ha-1 urea+150 kg.ha-1 triple superphosphate), 50% chemical fertilizer + biofertilizer (Azoto barvar + Barvar 2) and Vermicompost (10 ton.ha-1). Results showed that the highest faba bean leaf number was devoted to the 100% chemical fertilizer. The highest values for faba bean yield components were observed in 1:1 intercropping pattern. The highest land equivalent ratio and relative yield total at all fertilizer levels was devoted to 1-1 row intercropping. Also at 2:2 strip intercropping pattern the Vermicompost fertilizer had the highest land equivalent ratio (1.35). The highest relative value total was obtained in 1:1 row intercropping pattern with application of 100% chemical fertilizer that indicates the economic advantage of this planting pattern.
