The Effect of Mycorrhiza Biofertilizer on Yield and Yield Components of Linseed (Linum usitatissimum L.) and Fenugreek (Trigonella foenum-graecum L.) in Intercropping

In order to study the effect of mycorrhiza fertilizer application on the growth and yield of linseed in intercropping with fenugreek, a field experiment was conducted at research farm of Yasouj University, agricultural college in 2017. Experimental arrangement was factorial based on randomized complete block design with three replications and 15 treatments. The experimental factors were application of biofertilizer in three levels as non- bio fertilizer application (control), application of mycorrhiza fungus Funneliformis mosseaeand Rhizophagus irregularis species and cropping system in five levels, linseed sole cropping, fenugreek sole cropping and intercropping of linseed- fenugreek with ratios 1:1, 1:2 and 2:1. The results showed that the yield of linseed and fenugreek increased under the influence of mycorrhiza bio fertilizer. Also in between the cropping systems the highest grain yield of both linseed (233 g .m-2) and fenugreek plants (221.6 g.m-2) achieved from sole cropping systems. The highest seed oil percent (41.27%) of linseed was found in 1:1 ratio of linseed-Fenugreek intercropping with the application of Rhizophagus irregularis mycorrhiza fungus. Land equal ratio (LER) in all experimental intercropping system was higher than one that indicating the beneficial effects of linseed intercropping with Fenugreek compared to sole cropping of each. Based on the results, the cultivation ratio of one row of fenugreek: one row of linseed with Funneliformis mosseaemycorrhiza fungus application can be introduced.
