The long-term effect of 87.3 kg/ha P on the yield elements and nutrient content of maize was studied at the National Long-Term Fertilization Experiment of the Karcag Research Institute in Hungary. 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...

Field experiment was conducted on clay loam soil during winter season of 2010-2011 and 2011-2012 at the Research Farm, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the influence of sulphur (S) levels and irrigation on quality and yield of mustard (cv. 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...

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...

The present study was undertaken to sequentially fractionate nickel (Ni) in soils of divergent physicochemical characteristics and evaluate the contribution of different fractions towards plant uptake. 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%...

The study evaluates the effect of liming materials application in combination with NPK fertilizer and borax on macronutrient contents (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg)), in an extremely acid soil and raspberry leaves and fruits during a two-year period. 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...

Effects of 3,4-dimethylpyrazole phosphate and dicyandiamide on nitrous oxide emission in a greenhouse vegetable soilOriginal Paper

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%...

Effect of temperature on adsorption-desorption behaviour of triazophos in Indian soilsOriginal Paper

S. Rani, D. Sud

Plant Soil Environ., 2015, 61(1):36-42 | DOI: 10.17221/704/2014-PSE  

The present study investigated the adsorption-desorption behaviour of triazophos on Indian soils at 10, 20 and 40°C using batch equilibrium technique. Results revealed that adsorption isotherms were explained better by Freundlich model and adsorption coefficient (K_f) 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...

Moisture induced changes of volume and density of some cereal seedsOriginal Paper

Plant Soil Environ., 2015, 61(1):43-48 | DOI: 10.17221/767/2014-PSE  

The effect of wetting in the density and volume of seeds of barley, rye and two cultivars of wheat was determined. 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...
