In all agricultural activities, soil works are, according to classical technology, complex actions involving high energy expenditure making productions profitable conditional on the correct execution and during the optimal period. The influence of minimal work on the modification of the physical attributes of the soil is mainly explained by reducing field traffic, mobilising the soil to a much lesser extent than the classical system, modifying biological activity in the soil as a consequence of the ratio between porous and solid parts, as well as by working during the optimal period of performance. In order to implement, in production, the most efficient soil work and weed control technologies, in order to obtain high productions at the lowest cost, we recommend the following: when growing maize on the territory of Chişineu Criş, Arad County, Romania, account must be taken of the physical and chemical properties of the soil, as well as of climate conditions, with direct reference to temperature and precipitation. In view of the sensitivity of maize to weeding, we recommend choosing herbicides according to the composition of weed species Results require the use of the classic variant of soil work, where the highest productions have been obtained, but do not exclude some variants of minimal works. An important argument in support of the research carried out is the value of the main indicators of economic efficiency, which attest to the profitability of maize crops. When cultivating maize on the territory of Chişineu Criş, account should be taken of the physical and chemical properties of the soil, as well as of climate conditions, with direct reference to temperature and precipitation. In view of the sensitivity of maize when weeding, we recommend choosing herbicides according to the floral composition of weed species. Results require the use of classical tillage, in which the highest productions were obtained, without excluding some variants of minimum tillage.
