“…Row spacing did significantly influence the individual saturated stearic fatty acid, the monounsaturated oleic and vaccenic fatty acids and the polyunsaturated α-linolenic fatty acid contents (p = 0.0053, p = 0.0052, p = 0.0012 and p = 0.0125, respectively, Table 6). This is in line with El-Satar et al [56], Bellaloui et al [59] and Boydak et al [60] who stated that fatty acid composition of sunflower and soybeans are also significantly influenced by row spacing. Table S1).…”

“…This is in line with Kayaҫetіn et al [34] who observed a significant decrease in the percentage of crude oil in mustard along with an increase in row spacing. The same pattern was observed for sunflower (Helianthus annuus L.) and safflower according to El-Satar et al [56] and Eryiğit et al [48] who additionally observed a significant effect for year. In contrast, the oil content of sesame cultivated in Turkey was not significantly affected by row spacing in both years of cultivation [47] whereas Rahnama and Bakhshandeh [35] showed that the oil yield of sesame cultivated in Iran significantly decreased with increased row spacing from 37.5 to 60 cm.…”

Impact of Row Spacing, Sowing Density and Nitrogen Fertilization on Yield and Quality Traits of chia (Salvia Hispanica L.) Cultivated in southwestern Germany

To obtain high chia seed yields and seed qualities, a suitable crop management system needs to be developed for the given growing conditions in southwestern Germany. Field experiments were conducted at the experimental station Ihinger Hof in two consecutive years (2016, 2017). The study aimed to evaluate yield and quality traits of chia depending on different (i) row spacing (35, 50 and 75 cm), (ii) sowing densities (1, 1.5 and 2 kg ha−1) and, (iii) N-fertilization rates (0, 20 and 40 kg N ha−1). It consisted of three independent, completely randomized field experiments with three replications. Results showed that chia seed yields ranged from 618.39 to 1171.33 kg ha−1 and that a thousand seed mass of 1.14 to 1.24 g could be obtained. Crude protein-, crude oil- and mucilage contents varied from 18.11–23.91%, 32.16–33.78% and 10.00–13.74%, respectively. Results indicated that the year of cultivation and the accompanied environmental conditions, like precipitation or temperature, influenced the determined traits more than the applied agronomic practices. As average seed yields exceeded those obtained in the countries of origin (Mexico, Guatemala) while having comparable quality characteristics, chia holds great potential as an alternative crop for farmers in southwestern Germany.

“…This may be due to that plants grown under lower density have more availability of the environmental factors and less competition and consequently increase plant ability to build up metabolites. These results are in line with those obtained by Ali et al (2012), Hafiz et al (2014) and Abd El-Satar et al (2017).…”

A field experiment was carried out at the Agronomy Department Farm, Faculty of Agriculture, Assiut University during 2017 and 2018 seasons to study the effect of plant density and nitrogen fertilizer splitting on the production of sunflower. The experiment was laid out in Randomized Complete Block Design (RCBD) in split-plot arrangement with four replications. Plant density (46666, 28000, 20000 plants/fed.) were assigned in main plots and three treatments of nitrogen fertilizer splitting (2 and 3 doses) were arranged in sub-plots. The obtained results showed that plant height, seed weight per plant, seed yield (kg fed‾ ˡ), oil percentage (%) and oil yield (kg fed‾ ˡ) were affected significantly by plant density in both seasons. Plant density 20000 plants /fed gave the highest mean values of seed yield fed‾ ˡ (2669.14 and 2569.59 kg /fed.) and oil yield fed‾ ˡ (990.47 and 915.21 kg/fed, in the first and second seasons, respectively). Additionally, Splitting nitrogen fertilizer into three doses (N1) gave the highest mean values for mention traits in both seasons. There was significant interaction between plant density and splitting nitrogen fertilizer on all the studied traits in the both seasons, except plant height. Plant density 20000 plants /fed when received nitrogen fertilizer at three doses (N1) gave the highest mean values of seed yield fed. (2833.33 and 2728.58 kg/fed.) in the both seasons.

A field experiment was conducted at the Agronomy Department Farm, Faculty of Agriculture, Assiut University during 2017 and 2018 seasons to study the response of two sunflower cultivars to foliar spray by different zinc oxide nanoparticles concentrations. The field experiment was carried out in a randomized complete block design (RCBD) using a strip plot arrangement with three replications. Zinc oxide nanoparticles (ZnO NPs) concentrations (control, 100, 200, 300, 400 and 500 ppm) were allotted horizontally, while two sunflower cultivars (Sakha-53 and Giza-102) were assigned vertically. The obtained results showed that number of seeds head-1 , seed index and seed weight head-1 (g), Seed yield (kg fed.-1), oil percentage (%) and oil yield (kg fed.-1) were affected significantly by different zinc oxide nanoparticles concentrations in both seasons, except number of seeds head-1 in the second season. Sunflower plants which were sprayed by 200 ppm ZnO NPs gave the highest mean values of seed yield fed.-1 (1751.99 and 1515.18 kg/fed) and oil yield fed.-1 (676.79 and 600.81 kg/fed) in the first and second seasons, respectively. Furthermore, Giza102 sunflower cultivar gave the highest means for mention traits in the two growing seasons. Also, the interaction between ZnO NPs concentrations and sunflower cultivars had a significant (P≤0.01) effect on the all studied traits in both seasons. Giza 102 plants which were sprayed by 200 ppm ZnO NPs concentration gave the highest mean values of oil yield (723.61and 701.37 kg/fed in the first and second seasons, respectively).
