This study was conducted to investigate toxic effects of Pb on growth and nutrient uptake in Black gram. Black gram was subjected to seven (5, 10, 25, 50, 75, 100 & 200 kg-1) levels of lead. Due to Pb toxicity, plant growth was adversely affected and relatively a severe reduction in root biomass was recorded. The Pb accumulation increased with the increase in lead concentrations. The uptake of different nutrients, i.e., N, P, K, Ca and Mg was reduced in black gram due to the lead treatment.

Seasonal changes were investigated in concentrations of biogenic substances in the surface microlayer and subsurface water in ponds in the city of Słupsk (Northern Poland). Water samples from the surface microlayer were collected using the Garrett screen. Those water samples were analysed to determine concentrations of nitrogen and phosphorus compounds. It was found that biogenic substances are accumulated in the surface microlayer to a greater extent than in the subsurface water layer. This accumulation is subjected to seasonal changes. The source of the analysed nitrogen and phosphorus compounds in the surface microlayer was connected with their concentration in subsurface water.

Despite the importance of calcium in many fruit species and the effects of calcium application, there is little or no reliable information on the effect of CaCl2 spray at different fruit development stages on the fruit mineral nutrient content during the growing season and at harvest. Therefore, this study has been conducted to evaluate the effect of calcium chloride (CaCl2, 15 g L-1) spray at different fruit development stages on the accumulation Ca and other macronutrients in cv. Hayward kiwifruit grown at two locations. In order to find the absorbality of Ca at different spraying times, fruits were harvested 7 days after a Ca treatment. Additionally, the mineral composition of kwifruit was determined at the stage of harvest ripeness. The results showed that the absorbality of Ca by kiwifruit from Ca spray decreased significantly with the progressing fruit development. The highest fruit Ca content was found when the fruit plants were sprayed at 35+80 DAFB and 35+80+120 DAFB, irrespectively of the location of an orchard. At a later Ca spraying application, the N content in kiwifruit significantly decreased, but the K and Mg content slightly increased. In contrast, the K/Ca, N/Ca, Mg/Ca and (K+Mg)/Ca ratios of CaCl2 sprayed fruits was lower than in the control and the ratio values were more balanced in the Ca treated fruit than in the control. Overall, three CaCl2 (15 g L-1) sprays could effectively improve the fruit quality by balancing the Ca ratio to other macronutrients. Therefore, Ca spray treatments could be a recommended treatment in growing cv. Hayward kiwifruit.

The aim of this research is to study accumulation of Chromium along with nutrients and its effect on the growth of Paddy plant (Oryza sativa L). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morphological parameters like root length, shoot length and dry weight of plants and accumulation of nutrients along with Cr content were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphological parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content paddy seedlings. Similarly nutrient accumulation also affected by increasing concentrations of chromium.

In humic, mesotrophic and eutrophic lakes (Masurian Lakeland, Poland) 100–200 samples of water were taken with the Larsson’ plate from 0.5 mm surface microlayer (SM) and compared with the subsurface water (SSW). The concentrations of dissolved (in filtered water) and total (unfiltered) Kjeldahl nitrogen (organic and ammonium) (DKN, TKN) and phosphorus (DP, TP) were measured and the concentration of their particulate (sestonic) forms (PON, PP) estimated. The enrichment (accumulation) factor (Ef) values were calculated as the ratio of nutrients concentration in SM versus SSW. Accumulation of nutrients in SM was a common phenomena in the studied lakes. However, it occurred more frequently (close to 100% of samples) for TKN than for TP (60–70%) as well as generally more frequently in humic lake than in other lakes. Mean values of Ef for TKN were 2.6, 2.2 and 1.6 respectively for the humic, meso- and eutrophic lakes but the accumulation values for TP were lower – 2.3, 2.1 and 1.5 respectively for above lakes (the differences between concentrations in both layers as well as between lakes are significant). It means that in average the concentration of N and P in SM is at least two times greater than in SSW in humic and mesotrophic lakes. Accumulation of particulate forms of nutrients (PP, PKN) in SM is less frequent but the respective values of Ef are higher comparing with the total content of these nutrients and again higher for nitrogen than phosphorus. The higher values of the weight ration N:P (33–76) in seston were found in SM in comparison with SSW (24–56) as well as higher contribution of particulate (sestonic) N (PON) to its total content in respective layer. Generally higher values of these two indices were found in both layers of humic lake than in other lakes. No significant differences were found for the Ef values calculated for spring and summer periods (expected to differ in organic matter production and algae biomass) as well as for different sites (open water, shore region) in the lakes. It was concluded that the humic substances of allochthonous origin (mostly refractory and of high molecular weight) possibly predominate in the surface microlayer of the humic lake and support the stability and specificity of this layer in comparison with deeper water layer as well as in comparison with the meso- and eutrophic lakes. In highly productive, eutrophic lake, the surface microlayer is less distinct and stable possibly because of relatively greater role of in situ autochthonous production of labile organic matter which shows low affinity to the air-water interface. The surface microlayer in mesotrophic lake displays somehow intermediate properties in comparison with humic and eutrophic lakes.

Maize is an agronomic cereal species that is sensitive to nutrient applications, especially nitrogen. Field experiments were conducted in 2011 and 2012 to evaluate the effect of nitrogen and mulching using dried weeds on maize growth and nutrient accumulation. The study was located in the Research Farm of the Agricultural Science Education Unit of the Delta State University, Abraka, Nigeria ((latitude 50 46’N and longitude 60 5’E). The experiment consist of eight (8) treatments (i) control (ii) 40kgNha-1 (iii) 80kgNha-1 (iv) 120kgNha-1 (v) 4.5t ha-1 Panicum maximum + 40kgNha-1 (vi) 4.5t ha-1 Pueraria phaseoloides + 40kgNha-1 (vii) 4.5t ha-1 Eleusine indica + 40kgNha-1 (viii) 4.5t ha-1 Stylosanthes gracilis + 40kgNha-1. The treatments were replicated three times. From research results, the combination of Pueraria phaseoloides with 40kgNha-1 showed higher maize plant height, foliage development attributes, shoot dry matter, crop growth indices and nutrient uptake compared to other combinations, while only nitrogen application of 120kgNha-1 recorded the highest in all the treatments. It can be concluded based on the results in this study, that legume based weeds as mulch can be supplemented with nitrogen to improve maize growth.

Zinc is a heavy metal; this element is considered as environmental hazard.Toxicity effects of Zinc on growth and development of plants including inhibition of germination process decrease of growth and biomass of plant. The aim of this research is to study accumulation of Zinc along with nutrients and its effect on the growth of Cow pea plant (Vigna unguiculata.L). Thus, cow pea seedlings grown in petriplates lined with filter paper undergoing, different treatments of Zinc (control, 10, 25, 50, 75, 100, 150 and 200 ppm). After one week seedlings were removed and morpho physiological parameters like root length, shoot length and dry weight of plants and accumulation of nutrients along with Zinc in roots and shoots were determined. The results indicated that the concentrations more than Zinc 50 mg/L zinc cause the reduction of morphophysiology parameters in the treatment plants rather than control plant and zinc addition in the cultures caused enhancement of zinc content in roots and shoots of cow pea seedlings. Similarly nutrient accumulation also affected by increasing concentrations of cow pea. It was also noted that accumulation of zinc in the roots was much higher than the shoots of the seedlings under treatment.

The research objective was to determine and compare dry matter, crude protein, mineral elements (total), dietary fiber, easily hydrolysable sugars, vitamin C, and minerals (K, Na, Mg, Cu) as well as the content of epicatechin and phenolic acids (homovanillic, chlorogenic, caffeic, coumaric, and ferulic) in the flesh and peel of ‘Šampion’ cv. apples grafted on 4 different rootstocks types: M.26, P2, M.9, and P22 in 2014–2015. The apples from trees grafted on the P22 rootstock had the highest content of dry matter, crude protein, fiber, easily hydrolysable sugars, and vitamin C. The highest mineral compound concentration was exhibited by apples from trees growing on rootstocks P22, P2, and M.9. The highest concentration of phenolic acids was determined in the peel of fruits from trees growing on P22 and M.9. The observations confirm that rootstocks characterized by the lowest growth rate (P22, M.9) ensure the highest accumulation of nutrients in ‘Šampion’ fruits.
