Yield and Yield Components of Faba Bean (Vicia faba L.) in Intercropping with Moldavian Balm (Dracocephalum moldavica) under Organic and Chemical Fertilizers

The effect of different fertilizer treatments on intercropping of faba bean and Moldavian balm, by field experiment was studied as factorial on the bases of randomized complete block design with three replications in 2014. The first factor was cropping system at five levels including sole cropping of faba bean, sole cropping of Moldavian balm and three intercropping ratios (1:1, 2:2 and 2:4) of faba bean with Moldavian balm, and the second factor was fertilizer at three levels including nitrogen and phosphorus chemical fertilizer, bio-fertilizer (Azoto Barvar Barvar-2) 50% of chemical fertilizers, and vermicompost. The results showed that the maximum chlorophyll content index and leaf number per plant was obtained in chemical fertilizer treatment. The highest plant height (56.8 cm) was observed in 1:1 intercropping system. The effect of fertilizer treatment was not significant on plant height and grain per pod. Chemical fertilizer had significant effect on 100-grain weight and harvest index as compared to other fertilizer treatments. The highest amount of number of pods per plant (3.52) was obtained from sole cropping and chemical fertilizer application. The maximum grain yield per occupied unit area was observed in sole cropping (259.2 g.m-2) and among fertilizer treatments was belonged to 100% chemical fertilizer (202.1 g.m-2). Also at all treatments the land equivalent ratio and total relative value were obtained more than 1 and from this comment intercropping of 2:2 faba bean-Moldavian balm were the highest. Therefore, cropping system of 2:2 faba bean-Moldavian balm is introduced as advantageous system.
