Effect of Some Safety Growth Stimulants and Zinc Treatments on Growth, Seeds Yield, Chemical Constituents, Oil Productivity and Fixed Oil Constituents of Chia (Salvia Hispanica L.) Plant

Abstract

This study was carried out at the Experimental Farm and in the Laboratories of Horticulture Departments, Faculty of Agriculture at Moshtohor, Benha Univ., during 2018/2019 and 2019/2020 seasons. The aim of this study was to investigate the possibility of improving growth, seeds yield, oil productivity and fixed oil constituents of chia (Salvia hispanica L.) plants by some safety growth stimulants treatments i.e. chitosan, ascobien, humic and glutamic acids and micronutrients zinc (Zn) i.e., control (tap water), 100 and 200 ppm, as well as their combinations. Plants were sprayed with safety growth stimulants gave the significantly highest mean values for all studied characteristics i.e., plant height, number of branches per plant, plant fresh and dry weights, seeds yield/plant, weight of 1000 seeds, chlorophyll a, b, carotenoids, N, P, K, total carbohydrates, fixed oil percentage, and fatty acids determination of chia (Salvia hispanica L.) plants, with superior for humic acid at 5 ml/l followed by glutamic acid at 200 ppm in the first and second seasons. Meanwhile, ascobien at 200 ppm ranked the third values in this concern. Irrespective of control plants the lowest values of these parameters were scored by chitosan at 5 g/l in the 1 st and 2 nd seasons. As for zinc concentration treatments, there was appositive relationship between the values of abovementioned parameters and zinc concentration, hence as the concentration of zinc increased the values of these parameters increased till reached the highest increases at the highest concentration (200 ppm) in the two seasons. Furthermore, the combination of humic acid at 5ml/l showed to be the most effective one for inducing the highest values of these parameters especially those sprayed with the highest concentration of zinc (200 ppm). Chromatography analysis of chia fixed oil revealed the identification of seven components. The main component was α-linolenic acid (37.28 to 39.72%). The major components were α-linolenic acid, linoleic acid, oleic acid and palmitic acid. It can be concluded that humic acid at 5 m/l with Zn at 200 ppm was the best treatment for improving growth, seeds yield, fixed oil productivity, chemical constituents and fixed oil components of chia (Salvia hispanica L.) plant.

Evaluation of savory (Satureja hortensis L.) under organic farming system

“…Their strains generate carbon dioxide (CO 2 ), which lowers the pH of the soil; they also promote herb immunity against pathogens; they raise the plant's ability to take in nutrients, which contributes to an increase in photosynthesis [7] . These results are in accord with the research of [27] on gladiolus, [28] on marjoram and peppermint, [29] on sweet violet, [30] on chicory, and [31] on peppermint, who mention that applied bio-fertilizer EM can raise production. The high levels of gibberellin, auxin, and cytokinin found in chitosan are likely responsible for the remarkable outcomes of spraying high chitosan concentrations.…”

“…On the other hand, there is high significant between treatments in weight fixed oil ml/ plant and weight fixed oil L/fedd., were the highest values from (T9) Citric acid (3g/L)+ K humate (3g/L) recorded the best results were (20.10 and 21.32 ml/ plant) for weight fixed oil ml/ plant and (446.67 and 473.88 L/fedd.) for weight fixed oil L/fedd, followed by (T8) Citric acid (3g/L)+ K humate (2g/L).The former results were proved Manal M. Meligy 640 by Mohamed and Ghatas (2020) on chia plants., El-Hoseiny et al (2020) on mango trees., Mandour et al (2019) on strawberry plants and Hamad and Tantawy (2018) on sorghum plants. 6) showed that, the effect Citric acid and Potassium humate on roselle plants.…”

“…respectively and followed by (T8) Citric acid (3g/L)+ K humate (2g/L), then the treatment of (T3) Citric acid (3g/L). The former results were proved by Hamad and Tantawy (2018) on sorghum plants, Mohamed and Ghatas (2020) on chia plants, El-Hoseiny et al (2020) on mango trees and Abd EL-Kader ( 2016) on wheat plants., Maha (2016) on Ruby Seedless Grapevine Studied, the effect of humic acid, ascorbic acid and Citric acid used either separately or in combination form on physical and chemical properties of Ruby seedless grapevine. This research proved that, the foliar application had ability to increase and improve physical and chemical properties of Ruby seedless grapevine cultivar.…”

“…There is a study on mango trees mentioned that, humic acid (HA) and boric acid (BA) effects on plant morphological, physiological, biochemical, and genetic processes, which ultimately affect plant growth, yield, and fruit quality El-Hoseiny et al (2020) on mango trees. Mohamed and Ghatas (2020) on chia plants, illustrated that, the combinations of humic acid at 5m/l with Zn at 200 ppm could be used to improve growth, seeds yield, chemical constituents, fixed oil productivity and fixed oil constituents of chia (Salvia hispanica L.) plant. Hamad and Tantawy (2018) on sorghum plants, used three humic acids isolated from different sources, i.e., clayey soil (HAS); podrite (HAP) and compost (HAC) were used.…”

Influence of Some Biostimulants and Chemical Fertilizers on Growth, Seed Yield, Chemical Constituents, Oil Productivity and Fixed Oil Content of Chia (Salvia Hispanica L.) Plant Under Aswan Conditions

“…Moghith et al (2021) declared that the main components were αlinolenic acid (54.96 to 63.23%) linoleic acid (15.82 to 21.36), oleic acid (6.19 to 15.86%) and palmitic acid (6.30 to 8.15%). Mohamed and Ghatas (2020) on chia declared that the main component was α-linolenic acid (37.28 to 39.72%). The major components were αlinolenic acid, linoleic acid, oleic acid, and palmitic acid.…”
