Weed control is an important cultivation treatment in the cultivation of maize, while the time of conducting it, limited by the plant developmental stage, determines the yield height and financial outcome. However, the use of chemical plant protection products on ecological farms is not allowed, therefore, the level of obtained yields and economic effects of this species cultivation is largely affected...
Cereals are exposed to considerable losses caused by harmful insects. In the years of the study of production and economic effects of pest control in winter wheat, leaf beetle larvae damaged from 31.6 to 49.8% of leaf blade area. The aim of this study was to evaluate the effectiveness and economic efficiency of the insecticides applied in leaf beetle larvae control in winter wheat. The assessment...
The aim of this study was to evaluate weed infestation (the number, biomass and species composition) of husked and naked oats canopy depending on the soil tillage system (conventional, simplified with a catch crop, simplified, direct sowing) and the method of plant cultivation (mechanical and chemical) The study was carried out in 2000- -2002, in Alfisols, formed from loess. The subject of the investigation...
Haploid maize plants are obtained using in vitro androgenesis in anther cultures and isolated microsphores, as well as in vivo, through obtaining maternal haploid lines created as a result of pollination with an inducer. DH lines obtained in vivo are gaining importance in heterosis maize breeding. The aim of this study was to evaluate the genetic variability of 11 maize haploid offspring, derived...
Mid-forest meadows have a high natural value, due to preserving unique meadow and ecotone biotopes, similar to the natural state. Due to their dissimilarity, they also had a considerable effect on the functioning of forest ecosystems they border. The aim of the study conducted in 2006-2010 in the Bukówka river valley was to assess the natural values of mid-forest meadows with the Oświt method [2000]...
