This research was investigated to study the application of chemical and biofertilizers on growth, yield and fatty acids composition of safflower intercropped with faba bean based on a randomized complete block design with three replications at the Research Farm of University of Tabriz during two growing seasons of 2014-2015 and 2015-2016. Intercropping ratios of safflower and faba bean including 1:1, 2:1, and their sole cropping and four levels of fertilizers including no fertilizer, 100 percent chemical fertilizer, 30 percent and 60 percent chemical fertilizer + biofertilizer (Azoto barvar 1 and phosphate barvar 2) were evaluated. Results showed that the highest Chlorophyll content, plant height and number of branch per plant were devoted to safflower/faba bean intercropping (1:1) with application of 60 percent chemical plus biological fertilizers. Also, integrated use of chemical and biological fertilizers caused the increasing of seed yield, oil content (33.81 percent) and linoleic (76.97 percent) and linolenic (0.32 percent) fatty acids. The highest land equivalent ratio (1.41) was achieved in intercropped plants (1:1) with integrated use of 60 percent chemical and biological fertilizers. For both years, total actual yield loss for all intercrops was more than zero, which indicates the positive advantage of intercropping over the pure one. Overall, intercropping (safflower/faba bean) with integrated use of the chemical and biological fertilizers, can recommend as an appropriate manner for the production of safflower with a better quality and quantity.

This experiment was conducted to examine the effect of sowing date and different combinations of ajwain and isabgol intercropping on the grain yield, yield components, ajwain essential oil yield, weed control, and the mucilage percent of isabgol as split plot based on RCBD with three replications in Zabol University research farm in 2013. The main factors included two sowing dates of January 09 and February 08. The six additive cropping patterns including sole cropping of ajwain, sole cropping of isabgol, 25% isabgol + 100% ajwain, 50% isabgol + 100% ajwain, 75% isabgol + 100% ajwain, 100% isabgol + 100% ajwain comprising subplot. The results revealed that delayed sowing led to significant increase in ajwain essential oil percentage, however, seed and biological yield, essential oil yield and 1000-seed weight of ajwain decreased by 12.31, 13.7, 0.5 and 35.1%, respectively. In addition, sowing delaying did not have significantly impact on grain and biological yield of isabgol. Intercropping patterns significantly reduced yield and yield components of both crops. The highest seed yield of ajwain (2309 kg.ha-1) and isabgol (539 kg.ha-1) were obtained in sole cropping. The lowest dry weight of weeds was obtained from the planting date of January and cropping pattern of 100% isabgol + 100% ajwain. The highest LER was observed in cropping patterns of 50 and 75 of isabgol + 100% ajwain, that it is indicated yield advantage in intercropping over monocropping.

To study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at College of Agriculture, ShahedUniversity in Tehran, 2011. The main plots were allocated to different levels biofertilizer and chemicalfertilizer phosphorus in four levels viz. 1. Control (no fertilizer), 2. Biofertilizer (Nitroxin,biophospherous fertilizer 2), 3. Integrated fertilizer (bio fertilizers+ 50 percent chemical fertilizer), 4.Chemical fertilizer (triple super phosphate). The subplots were allocated to different combinations of 1.Sole alfalfa, 2. Sole fennel, 3. 100 percent alfalfa+ 50 percent fennel, 4. 100 percent alfalfa+ 100 percentfennel. Results showed that the highest amount of crude protein was obtained in alfalfa+ 50 percentfennel at control treatment and the highest dry matter digestibility in sole alfalfa at integrated fertilizingsystem. The lowest percentage of essential oil was obtained in alfalfa+ 50 percent fennel at integratedfertilizing system.
