A greenhouse experiment was performed to determine the effects of the fungicides containing cyprodinil as well as dimoxystrobin and epoxiconazole on the activity of soil enzymes: dehydrogenases, urease, acid phosphatase and alkaline phosphatase, depending on fungicide dose (0 - control, 1 - recommended dose, 10-fold dose and 100-fold dose), the method of soil management (soil cropped with spring barley cv. Start, and uncropped soil) and the time of fungicide action (14, 28, 42 and 56 days). The experiment was established on Eutric Cambisols with pHKCl = 6.7. It was found that the enzymatic activity of the soil was affected primarily by such...

The effects of phosphate solubilizing bacterium (Bacillus FS-3) application on phosphorus contents of tomato (Lycopersicon esculentum L.) plant, growing performance and phosphorus forms in soil were evaluated under greenhouse condition. Five different phosphorus fertilizer treatments (normal superphosphate, triple superphosphate, di-ammonium phosphate, phosphoric acid, and rock phosphate) with and without bacterium (Bacillus FS-3) were applied in pots as 344 kg P/ha. Basal fertilizers were applied to all the pots as 180 kg N/ha (NH4NO3 33% N), 100 kg K/ha (K2SO4 50% K2O). The...

The effect of three seedling treatments: T0, normal germination; T1, cotyledons removed; T2, cotyledons removed 5 days earlier than in T1; and two phosphorus levels (P0 and P30) on nodulation and nodule function in soybean [Glycine max (L.) Merr.] were investigated in nutrient solution culture. The number of nodules formed at P0 was in the order T2 > T0 > T1, but it was T0 > T2 > T1 at P30. Nodule dry weight per plant had the same tendency as the nodule number. Nodule size (dry...

Between 2002 and 2004 the evaluation method of resistance to common scab was tested on potato genetic resources. The resistance of potato tubers to common scab was evaluated in the greenhouse provocation tests with planting in naturally infested soil. The test was evaluated on the tubers of 26 varieties and hybrids of Solanum tuberosum derived from a potato genetic resource collection. Ten tubers of each sample were individually planted into three-liter pots containing infested soil. Analysis of variance confirmed significant differences among individual varieties and hybrids as well as among the years. A rating scale for the evaluation of resistance...
Effect of elevated atmospheric CO2 concentrations on growth and yield of blackgram (Vigna mungo L. Hepper) - a rainfed pulse crop

The response of blackgram (Vigna mungo L. Hepper) to two levels of elevated carbon dioxide (550 and 700 ppm) in terms of growth and yield was investigated and compared with ambient CO2 level (365 ppm) using open-top chambers. The growth parameters viz., length and weight of root and shoot, root:shoot ratio, leaf area and weight significantly increased at 700 ppm CO2 when compared with 550 ppm. The percentage increase in total biomass at 700 and 550 ppm CO2 was 65.4% and 39%, respectively compared to the ambient (chamber) control. The increase in total seed yield at 700 ppm (129%) was due to an increase in number of pods...
The influence of gypsum treatment on the acquirement of nutrients from soils by barley
J. Matula, M. Pechová
Plant Soil Environ., 2007, 53(2):89-96 | DOI: 10.17221/2299-PSE
The aim of the present paper was to determine the impact of gypsum treatment of soils on initial growth and nutrient uptake by spring barley. Topsoil from 36 different farmed fields was used for the research. Two variants were established for each soil: control - without gypsum application, and response variant - with the application of 3.3 ppm CaSO4.2 H2O. Barley was grown on these soils for 21 days in a plant growth chamber under controlled conditions of cultivation. Concentrations of nutrients (N, NO3-, P, S, K, Mg, Ca, Na, Fe, Mn, Zn, Cu, B and Mo) were determined in the yield of barley shoot biomass....
