To evaluate the effect of fertilizers and density of plants on yield and yield components of safflower (Carthamus tinctorius.L) which are the most important factors in integrated plant growth and sustainable management of agroecosystem in sustainable agriculture. This experiment was done factorial in randomized complete design with three replications in research farm of Gardening department Faculty of Agriculture Shahid Chamran University of Ahvaz in 2011-2012 growing season. The plots consisted 3 levels of fertilizers a1= 100% biologic fertilizer (Nitroplaskin, Phosphate Barvar-2 and Alkan) a2 = 100% chemical fertilizers (Nitrogen 152 Kg/ha, Phosphorus 108 Kg/ha and Potassium 100 Kg/ha) and a3= biofertilizer with 50% chemical fertilizer. And the other factor, was 3 levels of safflower densities (b1=13, b2=20 and b3=27 plants/m 2 ). Our results showed that the effect of fertilizer and density treatments and their interactions on number of capitula/plant, and the effect of density on...

2 Abstract: In order to study the effect of bio-fertilizer on yield and yields components of safflower under dry land conditions, an experiment was conducted as factorial based on randomized completed block design with three replications, Iran in 2008-2009. The factors consisted of three levels of nitrogen fertilizer (0, 30 and conventional consumption 60 kg/ha) and bio-fertilizer (non-inoculation, Azotobacter and Azosperillum). The results showed that nitrogen rates had significant effects on yield and yields components. Significant Increase nitrogen from zero to 30 kg/ha, but not 30 to 60 kg/ha and no significant differences between 30 and 60 kg/ ha was observed in most studied traits. increase observed in all characters. But between 30 and 60 kg/ha wasn't observe a significant difference and they were in same statistical class in most characters. Treated characters affected by bio-fertilizers. Using bio-fertilizers caused to significant increase in all characters. Using Azoto...

Information regarding the effect of foliar application of zinc and manganese on the yield and yield components of safflower (Carthamus tinctorius L. cv. Isfahan landrace) under conventional and ecological cropping systems is scarce. Therefore, a field experiment was conducted as split-plot based on Randomized Complete Block Design with three replications in 2011. Treatments were cropping systems (high, medium, low input and ecological cropping systems) as main plots and foliar application of micro-nutrients (no foliar application, 2000 ppm zinc chelate, 3000 ppm manganese chelate, 2000 ppm zinc chelate + 3000 ppm manganese chelate and water) as sub plots. Results of ANOVA showed significant effect of cropping system and foliar application on the number of seeds per head and number of heads per plant, and however significant interaction effect on 1000 seed weight, seed yield and biological yield. The highest 1000 seed weight (36.37 g), seed yield (4115.6 kg/ha) and biological yield (...
Growth and Development of Safflower (Carthamus tinctorius) under Rainfed Conditions
International Journal of Agriculture and Biology
Crop growth and development is imperative to study the plant behaviour under a set of environmental conditions. Genotypes may respond differently under same conditions according to their genetic makeup, photosynthesis and assimilation potential. Growth and development of safflower genotypes was studied through field experiments executed at PMAS-Arid Agriculture University, Rawalpindi during 2006-2007 and 2007-2008. Eight safflower genotypes Thori-78, SAF-30, SAF-31, SAF-32, Leed-00, SAF-128, SAF-129 and SAF-130 were evaluated for growth analysis viz. leaf area index (LAI), crop growth rate (CGR) and net assimilation rate carried out at 21 days interval after germination till maturity during both years. Significant differences were observed for the growth attributes among genotypes at different sampling intervals. LAI, CGR and NAR followed sigmoid pattern consistently increasing at the start of observation, attaining peaks and decreased thereafter till maturity. The decline in growth...
In order to study of yield and grain filling period of different cultivars of rain-fed safflower to improve seed yield, an experiment was conducted at Zanjan Agricultural Research Center Zanjan, Iran in 2006-2007. Seventeen safflower cultivars which were obtained from Maragheh Research Center, Maragheh, Iran for dry land farming were evaluated, using randomized complete block design in three replications. Results showed that safflower cultivars had significant differences on the probability level of 1% regarding grain filling period, grain filling rate, maximum of grain weight and thousand-grain weight and there were significant differences among cultivars regarding grain yield, oil yield and oil content on the probability level of 5%. The cultivar PI-537598 had the highest grain and oil yield (800 and 236.8 kg haG in average, respectively) and Isfahan variety had the 1 lowest ones (345.4 and 108 kg haG in average, respectively). Oil yield, maximum seed weight and grain filling 1 rate were positively and significantly correlated with seed yield. These results could be used to improve safflower seed yield via breeding.

Safflower (Carthamus tinctorius L.) is an annual oil crop that belongs to the Asteraceae family. The experimental studies were conducted at two different research stations in the Kurdistan Regional of Iraq to determine various liquid NPK application methods on the growth, yield, and yield components of three safflower varieties. The experimental design was a complete block design under split-plot system with three replications. NPK application methods (Foliar, Fertigation, Foliar + Fertigation) and no fertilizer application are the main plots. While three safflower varieties (Iden, AL-Shamia, and Zaafarani) as sub-plots. Foliar NPK application had the highest dry matter yield and seed yield of 29.544ton ha-1 and 7.185ton ha-1, respectively, at the average of both locations. Zaafarani safflower variety recorded the maximum dry matter yield and seed yield of 22.204ton ha-1 and 4.794ton ha-1, respectively, at the average of both locations. However, the statistical analysis for both loc...

In order to investigate the influence of biological and chemical fertilisers on morphological traits, yield and yield components of safflower (Carthamus tinctorius L.), a field experiment was conducted in Maragheh (37°23' N; 46°16' E), in north western Iran, for one year in the 2014 growing season. The effect of seven treatments was evaluated: T1 - control (no fertiliser application), T2 - seed inoculation with P biofertiliser (contains phosphate solubilising bacteria; Pantoea agglomerans strain P5 and Pseudomonas putida strain P13), T3 - seed inoculation with N biofertiliser (contains Azotobacter vinelandii strain O4), T4 - foliar application of iron chelate, T5 - soil application of complete NPK, T6: foliar application of manganese chelate, and T7 - foliar application of zinc sulphate. The result showed that although application of N biofertiliser did not have a significant effect on the evaluated traits, P biofertiliser slightly improved grain yield. However, the applicat...
To study the effect of nitrogen rate and plant density at different levels on yield, yield components and quality traits of safflower (cv. Giza 1) an experiment was conducted as split plot design in randomized complete block design arrangement with three replications, during the successive seasons 2010/11 and 2011/12. The factors consisted of four levels of nitrogen (0, 40, 80 and 120 kg N ha-1) and four different densities (80,000, 100,000, 133,000 and 200,000 plants ha-1). Different statistical analyses such as ANOVA, polynomial regression, correlation, and stepwise multiple linear regression were used. The multiple statistical procedures showed that the main effects of nitrogen rate and plant density levels were significant (P = 0.01) for yield and yield components studied. A rise in nitrogen rate and plant density increased seed and oil yield, whereas plant height, number of branches plant-1 , number of heads plant-1 , seed yield plant-1 and 1000-seed weight decreased as plant density increased. In general, the highest plant density (200,000 plants ha-1) and the nitrogen level (80 kg ha-1) was the best treatment in this research to attain high safflower seed yield under environmental conditions of Giza Governorate, Egypt. Polynomial models of seed, oil yield and yield components based on the ANOVA were fitted. Polynomial regression analysis indicated that the relationship
