Abstract
Salicylic acid (SA), a plant phenolic compound and calcium chloride have a great role on crop plants against biotic and abiotic stresses. This experiment was conducted to study the effects of foliar application of salicylic acid (S1=0, S2=50, S3=100 and S4=150 ppm) and calcium chloride (C1=0, C2=1.5 and C3=3 g/L) on cotton. The results showed that, salicylic acid increased the percentage of oil and nitrogen in seeds as well as the amount of chlorophyll content in the leaves, and this increased continued until S4=150ppm. Calcium chloride had no significant effect on them. The interaction between calcium chloride and salicylic acid had significant effect on the lint and grain yield in cotton and increased them. Biological yield, weight of seed per boll, weight of cotton per boll and number of boll per plant also affected by the interantion between of these two treatments. In thsese traits, although salicylic acid until S4 increased them, but the main effect of calcium chloride was up to C2. It was found unlike salicylic acid, which affectd on yield, yield components, photosynthesis piments and the content of mineral elements in seeds until S4, calcium chloride had a major effect on yield and yield components and this effect was until the level of C2.
