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.

Planting of various crops in intercropping may change the amount of nutrients uptake by plants because of morphological and physiological differences in roots. In order to investigate the metal micronutrients uptake of the crops in cereals-legume intercropping a field experiment was performed in 2014-2015 in the College of Agriculture of Darab, Shiraz University. Treatments included 10 monoculture (wheat, barley, triticale, pea and bean with and without weeds) and 6 intercropping (wheat + pea, wheat + faba bean, barley + pea, barley + faba bean, triticale + pea and triticale + faba bean with weeds) which laid out in a randomized complete block design (RCBD) with three replicates. Results showed that the treatments had a significant effect on the uptake of Fe, Zn, Cu and Mn by plants so that the highest content of Fe, Zn, Cu and Mn in cereals was obtained in weed-free monoculture triticale (353.2 ppm), barley+faba bean intercropping (20.18 ppm), wheat+faba bean intercropping (23.59 ppm) and weed-free wheat monoculture (28.22 ppm). The highest content of Fe, Zn, Cu and Mn in legumes was obtained in wheat+faba bean intercropping (673.1 ppm), barley+pea intercropping (26.24 ppm), triticale+faba bean intercropping (28.33 ppm) and weed-free faba bean monoculture (32.26 ppm). The ranking of micronutrients uptake by crops and weeds was Fe˃Mn˃Zn.

Gorgan is one of the most important regions for faba bean (Vicia faba L.) production in Iran. However, there is no enough quantitative information about the various aspects of production management of this crop plant. To investigate the effects of inter-row spacing, cultivar and seeding date on the yield of green pod and grain, this experiment was carried out at research farm of Gorgan University of agricultural sciences in 2011-2012 growing season. The experimental design was a randomized complete block design as split-plot factorial with four replications. Inter-row spacing (30, 45 and 60 cm) and factorial of planting dates (15 Nov. and 23 Dec. 2011) and cultivars (Barakat and French) were arranged in main- and sub-plots, respectively. The results indicated non-significant effect of cultivar and the significant (P = 0.01) effects of seeding date, inter-row spacing and their interactions on the grain, green pod and biological yields, and pod number per plant, while the effects of cultivars were not significant, statistically. Based on the obtained results, any increase in inter-row spacing or delaying in planting of faba bean will reduce the grain, green pod and biological yields. The maximum yield of green pods and grain yield (21753 and 4530 kg ha-1, respectively) produced in normal planting date (15 Nov.) and 30 cm inter-row spacing. In contrast, the lowest grain and green pod yield (2527 and 13041 kg ha-1, respectively) obtained from delayed planting date (23 Dec.) and 60 cm inter-row spacing.
