The article presents data on the study of the effect of foliar water-soluble mineral fertilizer NOVATEK Solub K-Max 10-5-30 on the biochemical composition and commercial quality of apple fruits. A rise in vitamin C from the introduction of NOVATEK at a rate of 2.5 kg/ha indicates the effectiveness of this drug for optimizing the content of ascorbic acid in fruits. An increase in the content of monosaccharides and a decrease in disaccharides were found for all the studied rates of consumption of agrochemicals. The use of mineral fertilizer “Novatek Solub K-Max” contributed to increase the dry weight of fruits. The application of this mineral fertilizer is recommended for inclusion in the industry regulations for Apple cultivation as one of the elements of the technology.

Corriveau, J., Gaudreau, L., Caron, J., Jenni, S. and Gosselin, A. 2012. Testing irrigation, day/night foliar spraying, foliar calcium and growth inhibitor possible as cultural practices to reduce tipburn in lettuce. Can. J. Plant Sci. 92: 889–899. Most of the lettuce produced in Quebec, Canada, is grown in organic soils in the area south of Montreal. Regularly, producers experience tipburn damage to their crop, a physiological disorder associated with Ca deficiency along the margins of young actively growing leaves. Therefore, active research is ongoing to reduce damage associated with this disorder. Two greenhouse trials on Romaine lettuce (Lactuca sativa L. ‘Sunbelt’) were conducted to measure the effect of day and night foliar water spraying, irrigation, foliar application of prohexadione calcium (a growth inhibitor) and foliar application of Ca on lettuce growth and incidence of tipburn. None of the treatments had a significant effect on biomass, dry weight, leaf number or leaf area in lettuce. However, the results show that frequent foliar applications of Ca as low as 90 mg L−1 Ca2+ resulted in a significant decreases in the number of leaves and percent leaf area with tipburn, and significant increases in Ca content in young leaves. Foliar water spraying, irrigation and foliar application of prohexadione calcium resulted in no significant differences in tipburn in greenhouse experiments. As greenhouse and field conditions may differ importantly, Ca application should be tested further at the field scale.

Abstract The study was carried out in the greenhouse of the Department of Forestry/College of Agriculture and Forestry/the University of Mosul for the period from 15/9/2020 to 15/8/2021 to study the effect of spraying with N.P.K nano and mineral fertilizer on some growth characteristics of Pinus brutia seedlings. The spraying process was carried out using two types of N.P.K nano fertilizer, the first is (20: 20: 20) and the second is (12:12:36), and N.P.K mineral fertilizer was used in two types, the first is (20: 20: 20) and the second is (12:12:36) at a concentration of 5 g. L-1 for both nano and mineral, and by four sprays (2 autumns + 2 spring). The results showed the superiority of nano fertilizer (20:20:20) over the rest of the treatments in terms of the increase in longitudinal and diagonal growth, root length and diameter, and the wet and dry weight of the vegetative mass, which amounted to 28.3167 cm, 3.8383 mm, 58.5333 cm, 5.52000 mm, 32.4703 g and 13.9210 g respectively. The mineral fertilizer (20:20:20) also showed significant superiority over all treatments as it gave 27.4833 cm, 3.5939 mm, 57.1778 cm, 5.26278 mm, 29.7901 g and 13.3387 for the studied traits, respectively, an increase in longitudinal and diagonal growth, root length, root diameter and wet and dry weight of the stem. The interaction between the two fertilizers N.P.K nano (20:20:20) and mineral N.P.K (20:20:20) was significantly superior by giving the highest average growth of all studied traits, as it gave 30,717 cm, 4.2680 mm, 61,000 cm, 5.8493 mm, 36.135 g and 15.8160, respectively.

The Impact

Limited water availability is one of the important abiotic factor affecting yield of wheat crop. Exogenous application of osmolytes is an important factor in reducing the stress due to water shortage. Keeping in view the role of proline and L-tryptophan (L-TRP) in stress alleviation, a study was carried out at the agricultural research area of the University College of Agriculture and Environmental Sciences, The Islamia University of Bahawalpur, Pakistan, during winter 2015-2016 to evaluate the impact of foliar applied proline and L-TRP on growth and photosynthetic efficiency of wheat grown under limited moisture supply. Drought stress was applied in three levels (I1 = control, I2  = drought stress at tillering stage and  I3 = drought stress at grain filling stage) while, foliar application of proline and L-TRP was done in six levels [T1 = control; T2 = proline (10 mM); T3 = proline (20 mM); T4 = L-TRP (10-4 M); T5 = L-TRP  (10-4 M) + proline (10 mM) and T6 = L-TRP (10-4 M) + proline (20 mM)]. The experimental results revealed that growth and photosynthetic efficiency of wheat were decreased due to reduced water supply. However, exogenously applied proline and L-TRP considerably ameliorated the effect of drought stress. Combined application of L-TRP (10-4 M) and proline (20 mM ) showed better results and induced tolerance to drought stress, in comparison with other treatments. Foliar application of proline and L-TRP also enhanced the photosynthetic rate which might be related with the improved photosynthetic pigments. Overall, exogenously applied proline and L-TRP mitigated the adverse effects of moisture deficit on growth and photosynthetic efficiency of wheat crop.

Abstract 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 application of complete NPK fertiliser improved most of the traits, compared to the control and biofertiliser treatment. The best performance was obtained by foliar application of manganese chelate and zinc sulphate. The results showed that micronutrient-deficiencies have to be managed to unlock the potential yield of safflower in semiarid production systems.

Novel textiles have received a lot of attention from researchers in the last decade due to some of their unique features. The introduction of intelligent materials into textile structures offers an opportunity to develop multifunctional textiles, such as sensing, reacting, conducting electricity and performing energy conversion operations. In this research work nanocomposite-based highly piezoelectric and electroactive β-phase new textile has been developed using the pad-dry-cure method. The deposition of poly (vinylidene fluoride) (PVDF) − carbon nanofillers (CNF) − tetraethyl orthosilicate (TEOS), Si(OCH2CH3)4 was acquired on a treated textile substrate using coating technique followed by evaporation to transform the passive (non-functional) textile into a dynamic textile with an enhanced piezoelectric β-phase. The aim of the study is the investigation of the impact the coating of textile via piezoelectric nanocomposites based PVDF-CNF (by optimizing piezoelectric crystalline phase). The chemical composition of CT/PVDF-CNC-TEOS textile was detected by qualitative elemental analysis (SEM/EDX). The added of 0.5% of CNF during the process provides material textiles with a piezoelectric β-phase of up to 50% has been measured by FTIR experiments. These results indicated that CNF has high efficiency in transforming the phase α introduced in the unloaded PVDF, to the β-phase in the case of nanocomposites. Consequently, this fabricated new textile exhibits glorious piezoelectric β-phase even with relatively low coating content of PVDF-CNF-TEOS. The study demonstrates that the pad-dry-cure method can potentially be used for the development of piezoelectric nanocomposite-coated wearable new textiles for sensors and energy harvesting applications. We believe that our study may inspire the research area for future advanced applications.

The Impact

The main purpose of this article was to determine the impact on the equilibrium of the local transport system from privileging EVs by permitting them to use bus lanes. The study used two sets of data: information on infrastructure and traffic management; and information on the recorded road network loads and traffic volumes generated by a given shopping centre—the E. Leclerc shopping centre (an important traffic generator within the city of Łódź, Poland). These sets were then used to develop a microsimulation traffic model for the shopping centre and the associated effects on the localised transport system. The model was constructed by means of the PTV Vissim software tool. An initial simulation was conducted that formed a basis for subsequent scenarios (in total, 17 simulations were performed). On the basis of the conducted analyses, it was established that—for the researched part of the transport system—privileging the still rather uncommon battery electric vehicles (BEVs) engendered a marginal deterioration of traffic conditions. At the same time, allowing BEVs to use bus lanes within the chosen research area had no negative impact on bus journey times.

The Impact

Considering the detrimental effects of salt stress on the physiological mechanisms of plants in terms of growth, development and productivity, intensive efforts are underway to improve plant tolerance to salinity. Hence, an experiment was conducted to assess the impact of the foliar application of salicylic acid (SA; 0.5 mM) on the physiological traits of fenugreek (Trigonellafoenum-graecum L.) plants grown under three salt concentrations (0, 75, and 150 mM NaCl). An increase in salt concentration generated a decrease in the chlorophyll content index (CCI); however, the foliar application of SA boosted the CCI. The malondialdehyde content increased in salt-stressed fenugreek plants, while a reduction in content was observed with SA. Likewise, SA application induced an accumulation of proline, total phenolics, and flavonoids. Moreover, further increases in total free amino acids and shikimic acid were observed with the foliar application of SA, in either control or salt-treated plants. Similar results were obtained for ascorbate peroxidase, peroxidase, polyphenol oxidase, and catalase with SA application. Hence, we concluded that the foliar application of SA ameliorates salinity, and it is a growth regulator that improves the tolerance of fenugreek plants under salt stress.

This paper presents the experimental database and corresponding statistical analysis (Part I), which serves as a basis to perform the corresponding parametric analysis and machine learning modelling (Part II) of a comprehensive study on organic soil strength and stiffness, stabilized via the wet soil mixing method. The experimental database includes unconfined compression tests performed under laboratory-controlled conditions to investigate the impact of soil type, the soil’s organic content, the soil’s initial natural water content, binder type, binder quantity, grout to soil ratio, water to binder ratio, curing time, temperature, curing relative humidity and carbon dioxide content on the stabilized organic specimens’ stiffness and strength. A descriptive statistical analysis complements the description of the experimental database, along with a qualitative study on the stabilization hydration process via scanning electron microscopy images. Results confirmed findings on the use of Portland cement alone and a mix of Portland cement with ground granulated blast furnace slag as suitable binders for soil stabilization. Findings on mixes including lime and magnesium oxide cements demonstrated minimal stabilization. Specimen size affected stiffness, but not the strength for mixes of peat and Portland cement. The experimental database, along with all produced data analyses, are available at the Texas Data Repository as indicated in the Data Availability Statement below, to allow for data reproducibility and promote the use of artificial intelligence and machine learning competing modelling techniques as the ones presented in Part II of this paper.
