Warsaw Univ. of Life Sci. – SGGW, Agricult. 52, 2008)Economic efficiency of growing and technological processesfor cerealsJAROSLAV JÁNSKÝ, IVA ŽIVĚLOVÁDepartment of Business and Economics, Mendel University of Agriculture and Forestry, Brno, CzechRepublicAbstract: Economic effi ciency of growing andtechnological processes for cereals. The paperdeals with the draft of silviculture/technologicalprocesses for selected crops in organic system offarming. The impact of recommended silviculturetechnologies on economics of selected field cropsgrowing was carried out in order to increasethe competitiveness as well as the comparisonto economic results in conventional system offarming, which can contribute to increasing shareof cereals grown on arable land thereby meetingincreasing demand for bio-products of organicorigin in the Czech Republic.Key words: organic farming, cereals, silviculture/technological processes, economic efficiency.INTRODUCTIONGrowth of crops is complex and includesa range of forms. Field crops are themost important among them. Thesesecure the main part of human nutrition.Nevertheless, field crops it is possibleto consider as „ecosystems in which isman not only important force, but forthis kind of ecosystem also the necessarycondition for its existence. Man usesfield crops so, that significant share ofits energy, which the crops gain from thephotosynthesis process, gets out duringthe harvesting from the place of rise andregulates the stream of energy into theplaces of need (Jánský 2005).The agriculture in the European conditionsshould be multifunctional, sustainableand competitive. Approximationor achieving the sustainable agriculturedemands: decrease of inputs, increasingthe efficiency of all used sources andgreater use of natural processes as biologicalnitrogen fixation, circulation ofnutrients, prevention in plant protectionand so on. These general principles mustbe realized in individual growing technologies.The system of organic farming,in adequate extent and in selectedconditions together with observance ofenvironment friendly or equilibriumrules in agro-systems is one of the ways,which could play very important rolefor sustainability of agriculture but withlower yields.GOAL AND METHODOLOGYThe result of this paper is formulation ofrecommended silviculture/technologicalprocesses of selected cereals in organicsystem of farming. Evaluation of theimpact of recommended silviculturetechnologies on selected cereals growingand comparison with economic resultsin conventional systems of farmingwas carried out for increasing thecompetitiveness. It is assumed that theachieved results contribute to increasethe share of crops grown on arable land
