<p>The present experimental investigation demonstrates the effect of nano-ZnO, nano-FeO and nano-ZnCuFe-oxide particles on the growth of mung (<em>Vigna radiata</em>) seedling. The study was carried out by spraying optimum concentrations of nanoparticles in suspension form on hydroponically grown test units and examining the effect on the shoot growth of seedlings. Based on biomass assay, it was found that the seedlings displayed good growth over control, demonstrating a positive effect of the nanoparticle treatment. The best performance was observed for nano-ZnCuFe-Oxide followed by nano-FeO and nano-ZnO. Absorption of nanoparticles by plant leaves was also detected by inductive coupled plasma/atomic emission spectroscopy.</p>

The present study demonstrates an effect of nano-ZnO particles on the growth of plant seedlings of mung (Vigna radiate) and gram (Cicer arietinum). The study was carried out in plant agar media to prevent precipitation of water-insoluble nanoparticles in the test units. Various concentrations of nano-ZnO particles in suspension form were introduced to the agar media, and their effect on the root and shoot growth of the seedlings was examined. The main experimental approach, using correlative light and scanning electron microscopy provided evidence of adsorption of nanoparticles on the root surface. Absorption of nanoparticles by seedlings root was also detected by inductive coupled plasma/atomic emission spectroscopy (ICP-AES). It was found that at certain optimum concentration, the seedlings displayed good growth over control, and beyond that, retardation in growth was observed.

Abstract Conventional Zinc (Zn) fertilization (e.g., zinc sulfate) often leads to poor availability in soils. Zinc oxide nanoparticles (nano ZnO) can be a potential solution, but their effect on crop photosynthetic activity isn’t well documented. The effects of nano ZnO (50, 100, 150, 200 mg L-1) and application methods (seed-coating, soil-drench, and foliar-spray) in comparison with ZnSO4 recommended dose were evaluated for plant height, biomass, chlorophyll pigments and photosystem efficiency in a greenhouse pot experiment. 100 mg L-1 of nano ZnO significantly increased the chlorophyll (Chl.) a, b, a+b, carotenoids (x+c), a+b/x+c, SPAD, leaf Chl., total chlorophyll content plant-1, plant height and total biological yield (by 18-30%, 33-67%, 22-38%, 14-21%, 14-27%, 12-19%, 12-23% 58-99%, 6-11% and 16-20%, respectively) and reduced Chl. a/b (by 6-22%) over the other treatments (p<0.01) irrespective of application methods. Nano ZnO applied at 100 mg L-1 significantly increased photochemical quenching (qP) and efficiency of photosystem II (EPSII) compared to 150 and 200 mg L-1 regardless of application methods. The positive correlations between Chl. a and Chl. b (r2 0.90), Chl. a+b and x+c (r2=0.71), SPAD and Chl. a (r2=0.90), SPAD and Chl. b (r2=0.94) and SPAD and Chl. a+b (r2=0.93) indicates a uniform enhancement in chlorophyll pigments; SPAD value, qP, EPSII, and growth and yield parameters. This elucidates that the application of nano ZnO at 100 mg L-1 promotes corn biochemical health and photosynthesis, irrespective of the application method. These findings have a great propounding for improving plant growth through nano ZnO bio-fortification in acidic Spodosols.

An experiment with seedlings of Alnus viridis was established on a clear-felled tract situated on a summit tableland of the Jizersk&eacute; hory Mts. (central Europe, Czech Republic) at an altitude of 980 m a.s.l. The aims of the experiment were (i) to evaluate the response of A. viridis to the application of a basic mixture containing crushed limestone and amphibolite and (ii) to assess the growth potential of the species in a poor acidic site under climatically harsh conditions. Alnus viridis showed a good growth performance and survival rate, its initial response to fertilization was positive. The height growth and expansion of crowns were slightly but significantly stimulated by the treatment, the survival rate was also increased, though not significantly. The amendment application temporarily increased the foliar Ca and Mg concentrations. The content of foliar P, of the most deficient macroelement, was not improved by the treatment. However, the positive effect of fertilization was short-lasting and unconvincing from the aspect of practical use. In the second half of the reference period the control started to gain on the fertilized variant and as for mean height and crown diameter, both variants got almost equalized eight growing seasons after the treatment.

In order to achieve optimal plant growth and production, essential nutrients must be readily available in adequate quantities and in a balanced proportion to give a good yield, especially cauliflower which has health benefits that may not be found in many other plants. For this purpose, this experiment was carried out during the seasons 2020-2021 in the on station of Bangladesh Agricultural Research Institute, Khulna under Smallholder Agricultural competitiveness project. Although the treatments showed a positive effect on yield, quality and economics but, T1 revealed most significant influence on all parameters under study as compared to T0 (control). For micronutrients and hormone, T1 treatment produced the highest curd yield (29.99 t ha-1) and the lowest (17.04 t ha-1) was control from the varietal effect the highest curd yield was (35.14 t ha-1) from V4 (It Amazuku 33) and the lowest was (16.21 t ha-1) from V5 (BARI Fulcopi-1). In case of combined effect, the highest curd yield (45.16 t ha-1) was obtained from T1V4 and the lowest curd yield (10.27 t ha-1) from T0V1. Therefore, it can be suggested that the highest curd yield and good shape cauliflower curd can be obtained application of Zn 8.83 kg/ha, B 3.5 kg/ha, Ma 8.43 kg/ha and Flora (Hormone) 2 ml/1 L of water. Therefore, foliar application of micronutrients and hormone is suitable way to feed the cauliflower crop to enhance the marketable yield and quality.

The fungal and bacterial population of leaf surface of <i>Hordeum vulgare</i> L. has ben described. The phyllosphere and phylloplane regions of green and yellow leaves harboured different dominant species. Bacteria mostly suppressed the fungal growth and possibility of biological control has been suggested. The effect of three amino acids and one organic acid on leaf mycoflora has been studied by foliar spray method. Stimulatory effect of different concentrations of the acids has been noticed. Preferential growth of selected forms of microorganisms may be encouraged by the acid application to act as a mean of biological control.

Pulses have significant role in the profitability of agriculture because of major proportion of our population depends on it due to its higher nutritional value, rich source of protein and low price. Pulses are also important component of animal feed and their dried straw is used as hay. In pulses, mungbean (Vigna radiata L.) is a vital crop. Boron has positive effect on growth and development, nitrogen assimilation and root growth. Low level of boron causes negative impact on growth, narrow leave expansion, restricted root elongation and morphological features of mungbean plant.

The issues of the process modeling of wear-resistant covers infusion of the NiCrBSi system, strengthened by the addition of solid powder materials are studied in the article. The results of a numerical study of the effect of heat current and thermophysical properties of materials on the process of heating and infusion of the cover are presented. The statements about the advantages of powders based on ZrO2 are demonstrated. Particular attention is paid to the issue of cracking in the cover after infusion. The assumption is substantiated about the positive effect of the addition of ZrO2 powders on the increase in the crack resistance of the cover.
