Abstract

Background and Objectives: Biodiversity in agricultural system caused to modifying the pest and diseases populations, also, it could be improved nutrient cycle and soil conservation via activation of soil microorganisms that caused to increasing in soil stability, soil erosion control and increasing in carbon sequestration. Crops and legumes Intercropping are a suitable system for increasing food production and reducing environmental impacts. So, one way to achieve sustainability in agriculture is to use multi-cropping and mixes systems. The purpose of this experiment was to investigate the effect of different barley and hairyvetch and phosphorus fertilizer patterns on LER index, dry matter yield and qualitative traits of barley and hairyvetch. Material and Methods: This research was conducted in experimental farm of Agricultural Faculty of Shahid Chamran University of Ahvaz at 2016-2017 growing season. Experimental design was randomized complete block as a factorial arrangement with three replications. The first factor was 8 planting patterns includes barley sole cropping, hairy vetch sole cropping, hairy vetch-barley Intercropping ratios includes 50+50, 25+75, 75+25, as replacement series, 100% barley+10%, 20% and 30% hairy vetch as additive series and mixed Intercropping. The second factor was two Phosphorus fertilizer type includes 150 Kg ha-1 triple superphosphate and 75 Kg ha-1 triple superphosphate+ biological fertilizer (Barwar2). Dry matter yield was determined by harvesting a 1 m2 area from each plot. The measured traits include: Crude protein (CP), water soluble carbohydrate (WSC), ash percent, dry matter digestible (DMD), acid detergent fiber (ADF), Neutral detergent fiber (NDF), Intercropping dry matter yield, barley relative yield, hairy vetch relative yield, and land equivalent ratio (LER). The plant density for barley and hairy vetch were 375 and 250 plant/m2 respectively. The harvest operation achieved at April in barley dough stage. Results and Discussions: The results showed the highest total dry matter (1074 gr m2) and LER=1. 2 was obtained at 100%barley+30% hairy vetch additive method. The highest Crude protein, dry mater digestible (DMD) and ash percent were observed at hairy vetch sole cropping treatment. The highest water soluble carbohydrate, NDF and fiber were found at 100%barley+30% hairy vetch additive method. Biological phosphorus fertilizer+ 75 Kg ha-1 P had the highest CP, DMD, ASH and NDF. But in WSC, CF and ADF, chemical fertilizer was the best treatment. Conclusion: The results showed that with increasing in hairy vetch ratio in Intercropping, the Crude protein increased. The barley sole cropping had the lowest Crude protein. The comparison of different planting pattern showed that with increasing in barley ratio and decreasing in hairy vetch ratio, WSC, NDF, ADF and CF was increased. Also with increasing in hairy vetch ratio, DMD, ASH and CP was increased. Totally the results revealed that the hairy vetch in Intercropping caused to increase in total forage yield and quality.
