A field study was conducted in order to evaluate the effects of intercropping and biofertilizers on yield and yield components of purslane (Portulaca oleracea L.) and dragon's head (Lallemantia iberica Fisch. and C.A. Mey). The experiment was factorial on the basis of a randomized complete block design with three replications. The first factor was an additive intercropping system including monocultured purslane, monocultured dragon's head, intercropping of 100% purslane + 25% dragon's head, intercropping of 100% purslane + 50% dragon's head, intercropping of 100% purslane + 75% dragon's head; the second factor was nutrient treatments including application of 50% inorganic N fertilizer (urea) + nitroxin, inorganic N fertilizer (urea), nitroxin and no fertilizer. Results showed that as the density of dragon's head increased, the number of branches in purslane decreased. In purslane, the number of capsules was significantly affected by intercropping and application of biofertilizers. In both crops, the effects of treatments on yield were significant. Results clearly showed that Relative Yield Total (RYT) was always higher in intercropping than monocultured systems. The highest RYT was observed in intercropping of 100% purslane + 50% dragon's head with the application of 50% inorganic N fertilizer (urea) + nitroxin. Therefore, combination usage of biofertilizers and inorganic N fertilizers can improve yields in purslane/dragon's head intercropping.

The results of the two-year comparative research of qualitative and quantitative traits of marigold seed of different genotypes in regard to the standard cultivar were analyzed. The highest yield of seed in both study years was registered in genotype "King orange", and the lowest in genotype "R". Concerning the quality of seed, that is, germination energy and total germination, the best results were established for genotype "King orange" and the poorest for genotype "R" in both study years. The highest absolute mass was registered in domestic cultivar "Domestic orange". Climatic conditions had great influence on yield and quality of marigold seed. In the first study year, with 2.5 times higher water sediment during the vegetation period, seed yield in all genotypes was higher compared to the second study year. Also, absolute mass of seed of all genotypes was higher in the first study year. However, germination energy and total germination for all genotypes was better in the second year, when the sum of temperatures during the vegetation period was 37580C compared to the first year when the sum of temperatures recorded was 35230C

“…However, flavonoids of inflorescences play a key role in the pharmacological activity and in most cases they are categorized for quercetin and rutin compounds [3,4]. Its seeds contain 15-20 % oil, 45-60 % of which constitute calendic acid [8]. Salicylic acid (SA) is a plant hormone and act as an antioxidant, produced by root cells.…”

Salicylic acid (SA) is an emerging plant growth regulator that acts as signaling molecule in plants under biotic and abiotic stresses. SA also exerts a stimulatory effect on different physiological processes of plant growth but its association with leaf pigments and flowering is less known. Current experiment was conducted to evaluate the effect of exogenous application of different doses of SA on marigold (Tagetes sp.) in greenhouse condition. Marigold (Tagetes sp. L) plants were randomly divided in 4 groups and treated exogenously with four different concentrations of SA (T0: 0 (only water), T1: 40, T2: 80 and T3: 120 mg/L). The solutions were sprayed on aerial parts of plant after 60 days of sowing. Results analysis showed that T3 (120 mg/L SA solution) showed maximum number of leaves plant-1 (30.38), highest plant height (50.63 cm), more number of inflorescence, greater stem diameter (7.84 mm), maximum fresh weight of flowers (11.90 g), and maximum dry weight of flower (1.25 g). Whereas, minimum number of leaves (22.74), lowest plant height (40.8 cm), less number of inflorescence, smaller stem diameter (4.75 mm), minimum fresh flower weight (7.13 g), and minimum dry flower weight (0.7 g) were observed in T0. Furthermore, various leaf pigments were found higher in T3. Present study concluded that T3 treatment of SA improved leaf pigments and morphometric parameters in Marigold. From the aforementioned results, it is suggested that 120 mg/L concentration of SA should be sprayed exogenously before flowering stage, on marigold plants for better growth and flower production.
