Abstract: The diagnostic experiment of influences of CO2 concentration doubling on winter wheat was conducted by using OTC-1 open top chamber.The results showed that when CO2 concentration was doubled in the chamber,growth and development,leaf area index,biomass and yield were all greatly increased compared with those in normal CO2 condition.This suggested that the increase of CO2 concentration in atmosphere will have positive effects on plant growth.

Abstract: An experiment with five different tillage systems and their influence on fuel consumption, labour requirement and yield of tested crops was carried out on Albic Luvisol in northwest Slavonia in the period of 1996.-2000. The compared tillage systems were: 1. conventional tillage system (CT), 2. reduced tillage system (RT), 3. conservation tillage system I (CP), 4. conservation tillage system II (CM), 5. no-tillage system (NT). The crop rotation was maize (Zea mays L.) - winter wheat (Triticum aestivum L.) – maize – winter wheat. Comparing the fuel consumption to CT system, RT system consumed 6.8% less, CP system 12.1% less, CM system 27.4% less, while NT system consumed even 82.7% less fuel. The labour requirement showed that RT system saved 7.6%, while CP system required 21.8% less, CM system 38.6% less labour, respectively. NT system saved 81.7% of labour in comparison to CT system. The highest yield of maize in the first experimental year was achieved under CT system and the lowest under RT system. In all others experimental years the highest yield of winter wheat and maize was achieved under CM system, while the lowest under RT system.

Abstract: The transport of aerosols and pollutants from continental India to the adjoining oceanic areas is a major topic of concern and several experimental campaigns have been conducted over the region focusing on aerosol characteristics and their climate implications. The present study analyzes the spectral aerosol optical depth (AOD) variations over Bay of Bengal (BoB) during Winter-Integrated Campaign for Aerosols, gases and Radiation Budget (W-ICARB) from 27 December 2008 to 30 January 2009 and investigates the influence of the adjoining landmass to the marine aerosol field. High AOD500 values (>0.7) occurred over northern BoB due to outflow of aerosols and pollutants from the densely populated Indo-Gangetic Plains (IGP); low AOD500 (0.1–0.2) was observed in central and southern BoB, far away from the mainland. The Angstrom exponent "α" was observed to be high (>1.2) near coastal waters, indicating relative abundance of accumulation-mode continental aerosols. On the other hand, over southern BoB its values dropped below ~0.7. National Center for Environmental Prediction (NCEP) reanalysis data on winds at 850 and 700 hPa, along with air-mass trajectories calculated using Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model, suggested transport of continental aerosols from central and northern India over the BoB. On the other hand, when the ship was crossing the eastern BoB, the aerosol loading was strongly affected by air-masses originating from Southeast Asia, causing an increase in AOD and α. Biomass-burning episodes over the region played an important role in the observed aerosol properties. Terra/Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) AOD550 and cruise measured AOD550 showed good agreement (R2 = 0.86 and 0.77, respectively) over BoB, exhibiting similar AOD and α spatio-temporal variation.
MIDAS - An Influence Diagram for Management of Mildew in Winter Wheat  [PDF]

Computer Science , 2013,
Abstract: We present a prototype of a decision support system for management of the fungal disease mildew in winter wheat. The prototype is based on an influence diagram which is used to determine the optimal time and dose of mildew treatments. This involves multiple decision opportunities over time, stochasticity, inaccurate information and incomplete knowledge. The paper describes the practical and theoretical problems encountered during the construction of the influence diagram, and also the experience with the prototype.

Abstract: The influence of high CdCl2 concentrations on winter wheat (Triticum aestivum L.) and canola (Brassica napus L.) etiolated shoots was studied. It is shown that if in canola high Cd concentrations caused full inhibition of weight and length increase of shoots, in wheat these Cd concentrations caused less effect. The influence of high Cd concentrations on lipid peroxidation in wheat in canola differs too. If in canola Cd treatment caused the increase of lipid peroxidation rate, in wheat in most wariants this treatment caused the decrease of lipid peroxidation rate. The very high peroxidase activity in wheat may be an important part of Cd-resistance mechanism in wheat shoots.
Physiological effects of ploughing corn straw under soil on flag-leaf resistance of winter wheat under lowly applying fertilizer condition

生态学报 , 2009,
Abstract: The change characteristic and the relation of chlorophyll content, photosynthesis rate, SOD activity, POD activity, malondialdenhyde content and soluble protein were studied in the condition of lowly applying fertilizer under the convention management condition through field plot experiment. The results indicated that the change of docking-stubble winter wheat flag leaf chlorophyll, photosynthesis speed, SOD and soluble protein content assume the single peak tendency along with the increasing amount of Ploughing Corn Straw under Soil; the change of POD and MDA assume the single valley tendency along with the increasing amount of Ploughing Corn Straw under Soil in the condition of Lowly applying fertilizer under the convention management condition, The effects of Ploughing corn Straw under Soil on the wheat flag leaf senescence mainly are to influence the level of protection enzyme, particularly the POD. Under this test condition, the rate of 9000 kg wheat straw /hm2 is best on each anti\|senility target, the value of anti\|senile membership function and the output; the rate of 15000 kg wheat straw /hm2 is worst. Therefore, lowly applying fertilizer under the convention management in this area, ploughing corn straw under soil had the most favorable effect at the rate of 9000 kg wheat straw /hm2.

Abstract: A field experiment with winter wheat (Triticum aestivum) on Orthic Luvisol was conducted for a period of eleven years. This study gives the ground to establish correctly the fertilizer rates, especially nitrogen, in accordance with the moisture conditions of the year. Winter precipitation (October-March) plays an especially important role because of the fact that it coincides with the timing of early spring dressing and gives opportunity for more precise determination of the nitrogen fertilizer rates. It was established that application of nitrogen at 120 kg ha-1 was unprofitable when autumn-winter precipitation sums were below 250 mm. Nitrogen fertilizer rates of 180 kg ha-1 could be used only when autumn-winter precipitation exceeded 350 mm. In order to quantify the connection between meteorological conditions and fertilizer utilization efficiency, a statistical analysis was used.

Abstract: Modern soil tillage systems based on different tools than mouldboard plough have very often stronger weed occurrence, which can be a serious problem for achieving high yields. An obvious solution for weed suppression is a herbicide, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate the interaction between soil tillage and herbicide, trial was set up in Valpovo in seasons 2008/09 - 2010/11. Two soil tillage systems (CT-conventional tillage, based on mouldboard ploughing, and CH-chiselling and disk harrowing, without ploughing) and five herbicide treatments (NH-control, no herbicides; H10- recommended dose of Herbaflex (2 l ha-1); H05-half dose of Herbaflex; F10- recommended dose of Fox (1.5 l ha-1); and F05-half dose of Fox) were applied to winter wheat crops. Results showed similar effects of soil tillage on the winter wheat yield, whereas different herbicide dosages showed similar weed suppression and influence on winter wheat yield.
