This factorial field experiment was done based on a randomized complete block design in Urmia University, Iran, in 2013 and was repeated in 2014. Treatments included two farming systems (high input and organic) and different intercropping patterns that alternated bitter vetch (Vicia ervilia L.) and safflower (Carthamus tinctorius L.) with row ratios of 2:2, 3:2, 4:2 and 5:2. Sole cropping of bitter vetch and safflower was used as the control. In both years, the 2:2 intercropping pattern had biomass yield advantages compared to sole cropping and the other intercropping ratios, based on greater land equivalent ratio values. Safflower had higher relative crowding coefficients, competitive ratio (CR) and aggressivity (A) values than bitter vetch. High-input farming was more effective than the organic system in both years. Safflower was the superior competitor when grown with bitter vetch, and its productivity dominated the total biomass yields. Thus, intercropping of safflower with bitter vetch has the potential to improve performance with high land-use efficiency.ARTICLE HISTORY
It has been shown that salicylic acid (SA) acts as an endogenous signal molecule responsible for inducing biotic and abiotic stress tolerance in plants. The effect of three application methods (Soil, Foliar and Priming) and four salicylic acid concentrations (0, 0.1, 0.5 and 1.0 mM) on chlorophyll a, b and total chlorophyll, carotenoids, proline, protein and soluble sugars of NaCl (4 ds/m) stressed white bean (Phaseulus vulgaris L.) was investigated. The results showed that the effect of applied concentrations and application methods on chlorophyll a and total chlorophyll, proline, protein and soluble sugars were significant. The interaction of concentrations and application methods used was significant on protein, proline and soluble sugars. According to the results, the greatest impact was belonged to the soil treatment which was not significantly different from priming. Among applied concentrations, the concentration of 0.1 and 0.5 mM were the most effective and the concentration of 1 mM was not significantly different from the control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
