Effects of Nano and Chemical Fertilizers on Physiological Efficiency and Essential Oil Yield of Borago Officinalis L.

Abstract

This study was conducted to compare the effects of nano and chemical fertilizers on physiological efficiency and essential oil yield of Borago officinalis L. during 2013 and 2014 crop years. The different levels of fertilizers were used as main factors in 11 levels including iron-sulphate and nanoiron, zinc and nano-zinc, urea and nano-urea, potassium sulphate and nano-potassium, micro-complete and micro-complete nanosuper and control. The application methods of fertilizers were considered as secondary factor (soil application, foliar application and combined application). Physiological efficiency of nitrogen, phosphorous, potassium, zinc and iron, dry and fresh weight of aerial parts, number of secondary branches, chlorophyll content, 100 grains and essence yield were evaluated. Our findings showed that chemical fertilizers had no beneficial effects in comparison to nano fertilizers (P > 0.05). In addition, nano-urea and urea fertilizers increased essential oil yield because of increased wet and dry weight of aerial parts and number of secondary branches. In conclusion, nano-fertilizers can be used in order to improve the essence production and also as environmentally friendly fertilizers.

Influence of Applying Seaweed Extracts and NPK Fertilizer on Vegetative Growth, Flowering Traits and Seed Yield of Borage (Borage officinalis L.)

“…6a-c). The current results agreed with the previous results 15,21,27,29,31,33,36 Leaves to shoot ratio didnʼt show significant differences due to the use of either seaweed extract or NPK fertilizer in comparison to the control treatment (Fig. 7a).…”

“…Additionally, nitrogen and magnesium elements can be released by chemical fertilizers and incorporated into the chlorophyll moleculeʼs porphyrin ring. Potassium enhances nitrogenʼs influence on photosynthesis through an oligodynamic role or participation in the energy transformation, activating kinases and osmotic absorption 27 . Current results agreed with other results 26,[28][29][30][31] .…”

Effect of Different Ratios Nano-Fertilizer and Gibberellic Acid on the Vegetative Growth and Chemical Compositions of Codiaeum Variegatum (L.) cv. Gold Dust

“…The increase in the vegetative weight may be attributed to the increase in the plant height and leaves number of treated plants. These results are in agreement with (Mahmoodi et al, 2018) on Borago officinalis L. and (Salama, 2012) on Phaseolus vulgaris L. and Zea mays L. indicated Nano-fertilizers increase availability of nutrient to the growing plant which increase chlorophyll formation, photosynthesis rate, dry matter production and result improve overall growth of the plant. Moreover, (El-Sayed, 2014) on Schefflera arboricola found that the application of GA 3 increased the fresh and dry weight of stems.…”

“…In this connection, (Singh, 2017b) reported that Nano-fertilizer enhance leaf area index, number of leaves/plant, dry matter production and rate of the photosynthesis which result more production and translocation of photosynthets to different parts of the plant. Similar results were reported by (Jameel and Al-Tai, 2018) on sweet fennel, cumin and anise and (Mahmoodi et al, 2018) on Borago officinalis L. As well as, (El-Khateeb et al, 2010) on Calia Secundiflora found that GA 3 gave marked increases in the fresh and dry weights of leaves, it can be attributed to the increase both plant height and number of leaves plant. Tables (3 and 4) revealed that the application of different ratios of Nano-fertilizer and GA 3 increased the fresh and dry weight of stems for Croton plants when compared with control.…”

Effective cultivation of corn on the drylands with the use of CAM liquid fertilisers by the “Tuman” innovative complex

“…The current unfavourable food situation in the world due to the lack of food for many countries requires the leading producers of agricultural products, which includes Russia, to increase the production of food, especially from plant-growing raw materials, as much as possible, despite the negative projected global warming and critical droughts recurring from year to year in many regions and in particular in the Russian Federation [1][2][3]. In solving this problem, it is necessary to further expand the planting of highly productive crops, which include corn [4][5][6], improve its cultivation technologies using innovative technical and technological products, in particular the use of nitrogen fertilisers [7][8][9][10] preferably in liquid form [1,4,8] based on a carbamide-ammonia mixture -CAM (CAM-32, CAM+S). CAM is a unique highly effective liquid fertiliser with a prolonged effect due to the versatile effect of three forms of nitrogen on plants: nitrate, ammonium and amide ones, and only the amide form can be absorbed by the vegetative part of agricultural plants [1,6].…”
