Assessment of the effectiveness of selected herbicides on weeds in crops of spring wheat
KAŠÍK, Ladislav
This thesis focuses on assessing the effectiveness of selected herbicides for spring wheat protection against most occurring dicotyledonous weeds. To verify the effectiveness of selected herbicides was small plot trial on the Farm Kašík, Blanné . The most frequent weeds were (Atriplex patula L., Capsella bursa - pastoris L., Stellaria media L., Thlaspi arvense L. and Tripleurospermum inodorum L.). In an attempt were applied four herbicides (MUSTANG FORTE, Sekator OD, Basagran Super , tank mix glean 75 WG + Dicopur M 750) at two different doses (the minimum and maximum doses recommended by the manufacturers). Effectiveness were evaluated in four measurements with the percentage of subjective estimation methods .

Measurement and evaluation of emission gas production in selected cattle operation.
KAŠÍK, Ladislav
Measurement and evaluation of emission gas production in the selected operation with cattle''. This thesis deals with environmental pollution, especially livestock production in agriculture. The work is based on the determination of emission gases NH3, CO2, NH4, and NO2 and water vapor in the barn with redholsteen cattle breeds in ZD Krásná Hora nad Vltavou a.s. This work also deals with ammonia in agriculture, greenhouse gases and methods, which determine their concentrations. Average concentrations of the gases were as follows: CO2 = 1 188, 73 mg. m-3, water vapor = 8 181.29 mg.m - 3, N2O = 0.535 mg.m-3, NH3 = 1.14 mg.m -3; CH4 = 4.81 mg.m-3. The total average amount of all measured concentrations is 9376, 45 mg.m-3.
