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...
In this study, the economic assessment of production of maize for grain cultivated in monoculture was presented, with the use of two ways of pre-sowing tillage system (direct sowing, full ploughing tillage), as compared with cultivation in crop rotation. In the years of the study, large fluctuations in maize cultivation profitability occurred, resulting from the level of yield connected with the course...
The aim of this experiment was to determine the effect of root excretions of spring cereal seedlings on seed germination of field pea and common vetch. The experiment carried out in March and April 2009 under laboratory conditions (in the IUNG laboratory) involved oat, barley, wheat, triticale, field pea and common vetch. Two concentrations of excretions were applied: I – corresponding to the effect...
W pracy przedstawiono regionalne zróżnicowanie uprawy kukurydzy na ziarno i kiszonkę w Polsce. Materiał źródłowy do analizy stanowiły dane statystyczne GUS z lat 2000-2006, zestawione według aktualnie obowiązującego podziału administracyjnego na województwa. Za pomocą analizy skupień k-Means wyodrębniono grupy województw zróżnicowanych ze względu na intensywność produkcji surowca kiszonkowego i ziarna...
