The soil of the experiment site is non-calcareous Luvic Phaeosem, and its soluble phosphorus (P) and zinc (Zn) content in 0-20 cm soil layer are: ammonium lactate P: 141.1 mg/kg and diethylene triamine pentaacetic acid (DTPA)Zn: 0.85 mg/kg, respectively. The effect of foliar Zn fertilization was studied at three levels of nitrogen (150, 200 and 250 kg/ha) and under 87.3 kg/ha P and 82.6 kg/ha K application in four replications. The applied Zn amount was 700 g/ha. We measured the grain yield and the thousand-kernel weight. Leaf and grain samples were analyzed for phosphorus, zinc, potassium, calcium, magnesium and manganese content. Foliar Zn application did not increase the yield significantly, but it enhanced the thousand-kernel weight. The element content did not change significantly - neither in leaves nor in kernels. Under the examined habitat circumstances even the long-term application of 87.3 kg/ha P dosage did not cause Zn deficiency to such an extent which would lead to significant yield depression of maize.

Varuna, T-59). Results revealed that yield attributes and yield of crop were highest with 60 kg S/ha, mostly at par with 45 kg S/ha. Double irrigation at flower initiation (30 days after sowing (DAS)) and siliqua development stages (60 DAS) was best with respect to growth, yield attributes, yield, S uptake and oil percent in seed. Effects of both S levels and irrigations on glucosinolate and fatty acid content were non-significant except on progoitrin. The erucic:oleic acid ratio was inversely related to the subsequent increase in S doses, thereby suggesting the qualitative improvement of oil with S application. Oil percent has a negative correlation with sinigrin and gluconapin content. The uptake of S was positively correlated with oleic acid content but showed lower or even negative correlation with other fatty acids. Therefore, irrigation (twice at 30 DAS and 60 DAS) in combination with 45 kg S/ha are recommended for improving yield attributes, yield, oil percent and S uptake of Indian mustard.

Abstract: Eastern galega is promising forage species for Central Europe, but little is known about its forage quality in terms of elemental composition. We asked how the concentrations of Cu, Zn, Ni, Cr, Pb and Cd in its herbage are affected by application of ammonium sulphate and by year. Changes in the content and bioaccumulation of trace elements of herbage eastern galega fertilized with 15N were investigated in a field three-year experiment. The study was conducted with a legume plant, i.e. eastern galega (Galega orientalis Lam.). The experiment was completely randomized and carried out in four replications with the following mineral fertilization: control, and nitrogen fertilization (15NH4)2SO4. The second factor was years of research (1st, 2nd, 3rd). Nitrogen 15N at 10.3 at % enrichment was applied in a form of (15NH4)2SO4 at the amount of 1.66 g/m2 in early spring. The measured concentrations of the selected heavy metals (except for Pb and Cd) were within the permissible limits for trace elements in feedstuffs specified by Polish and European standards. The applied nitrogen fertilization significantly influenced a reduction in the content of Cu, Zn and Cr in soil. Calculated average values of bioaccumulation factors for heavy metals: Cd > Cu > Zn = Ni > Pb > Cr. The low dose of a nitrogen fertilizer in the form of ammonium sulphate does not significantly affect an increase of the availability of heavy metals.

For this, fifteen bulk surface (0-15 cm) soil samples were collected from the cultivated fields of northwestern Indo-Gangetic alluvial plains. A pot experiment was conducted with these soils to assess the contribution of soil Ni fractions to plant uptake using soybean as test crop. Results showed that residual Ni was the most dominant fraction in soil constituting 3.19-63.6% of total Ni. The water soluble plus exchangeable Ni accounted for only 0.70-4.04% of total soil Ni. Organically bound Ni varied from 1.60-6.85% of total Ni; these values are relatively lower as compared to those reported for temperate soils. Correlation studies showed that the free iron oxide (Fe2O3) and soil organic carbon correlated with various fractions of Ni in soil. Water soluble plus exchangeable and organically bound are the dominant fractions which contributed positively and manganese oxide (MnO2) bound and residual fractions contributed negatively towards the phytoavailability of Ni in soil.

Liming increased soil pH, N mineral content, P, Ca and Mg soil content, while K content either increased (dolomite and borax application), or decreased (lime application). The N and P contents in raspberry leaves after liming increased significantly, but P content remained below the optimal values. Some treatments with lime caused a decrease in K content in leaves, while dolomite and borax application increased K content. Initially optimal Ca content in leaves increased significantly in the treatments with lime, but decreased after dolomite application. The Mg content in leaves increased after dolomite and borax application, but mainly remained below optimal values. Liming either did not alter or only slightly altered macronutrient contents in raspberry fruits.

China Title: Effects of 3,4-dimethylpyrazole phosphate and dicyandiamide on nitrous oxide emission in a greenhouse vegetable soil Abstract: A laboratory study was conducted to determine the effect of 3,4-dimethylpyrazole phosphate (DMPP) and dicyandiamide (DCD) on nitrous oxide (N2O) emission, mineral nitrogen (NH4+-N, NO3--N) contents, as well as ammonia oxidizing and denitrifying microbes in a greenhouse vegetable soil. Five treatments were established at 55% and 75% water filled pore space (WFPS): no fertilizer; urea; urea + manure (UM); urea + manure + DCD (UMDCD) and urea + manure + DMPP (UMDMPP). The application rate of urea and manure was 1800 kg N/ha and 1000 kg N/ha, respectively. DMPP and DCD were applied at the rate of 0.5% and 2% of urea-N application rate, respectively. Compared to UMDCD treatment, UMDMPP treatment significantly reduced N2O emission and NO3--N content and delayed ammonia oxidation, and showed a stronger inhibition effect on ammonium-oxidizing bacteria at both WFPS. Moreover, the copy numbers of nirS and nirK genes decreased significantly in the presence of DMPP at both WFPS, but were not affected by DCD. These results suggest that the application of DMPP is more effective than DCD on N2O mitigation in high N level vegetable soil, although the application rate of DMPP was one quarter that of DCD.

Results revealed that adsorption isotherms were explained better by Freundlich model and adsorption coefficient (Kf) decreased with increase in temperature indicating that adsorption was affected strongly by temperature. Moreover thermodynamic analysis showed that triazophos adsorption onto soil was spontaneous, exothermic and might have occurred through chemisorptions, hydrogen bonding or ligand-exchange interactions. Desorption results depicted that nearly 90% of the pesticide amount adsorbed by soil was retained by it at 10°C and the amount decreased with increase in temperature. Thus, the pesticide has a potential to contaminate surface and ground water at higher temperature due to weak adsorption on tested soils and release of more adsorbed pesticide during desorption with water. At temperature below 20°C, pesticide became almost immobile and therefore soil remediation may be required. The study highlights the importance of temperature in regulating the application of triazophos in soil.

Two levels of wetting were used: (i) 6 h wetting close to the end of imbibition; (ii) 24 h wetting close to the beginning of germination. The experimental results show that the variability of the seeds' volume and density in all tested states can be well described by the Gaussian distribution. The changes of the seed's volume and the seed's density caused by wetting can be then easily expressed via the changes of the distribution parameters. The increase in the seed's density and the seed's volume was the main effect of the wetting, but the level of the observed changes was variable for different crops and different degrees of wetting. Density increase was observed mainly in the case of imbibition, whereas longer wetting was connected mainly with changes of the seed's volume.
