Two field experiments were strict founded in 2004-2006 on a farm in Chlebówek. Locality is 20 km from Stargard and 5 km north-east of the village commune old oak wood - 53027'N and 15010'E. In the experiments, the effect of irrigation, tillage system and fertilization on yield and selected parameters of the physical properties of the soil. We tested two varieties of faba bean: The conducted experiments show that the use of irrigation and increasing doses of mineral fertilizers increases the yield of faba bean seeds of both varieties, traditional - 'Nadwiślański 'and modified -'Titus'. The use of simplifications tillage reduces, to a greater extent, yielding traditional varieties of faba bean. Increased mineral fertilizers under field irrigation increased water consumption, and thus decreased the supply layer to 50 cm. Improving water logging top soils decreased soil bulk density in a variation of 'Nadwiślański' and increased the variety 'Titus'. The use of simplified tillage systems, especially direct sowing, increases the bulk density of the upper layers of the soil. ...
The field experiment was carried out in 2004-2006 in Chlebówko localized 20 km from Stargard Szczeciński and 5 km north-east from Stara Dąbrowa commune - 53°27'N and 15°10'E. The area is elevated 62-72 m above mean se level (ASL). The influence of irrigation, tillage system, and NPK mineral nutrition on weed infestation of faba bean variety ‘Titus' with determined development rate, was evaluated. The weed infestation degree in the faba bean plantation depended on moisture conditions, fertilization rates, and tillage system. Irrigation increased the number, fresh weight, and dry matter of weeds, respectively by 92%, 130%, and 138%. Likewise, increasing nutrition elevated values of these parameters by 46%, 80%, and 95%. The tillage simplifications enhanced the weed population, particularly on irrigated and fertilized objects. Irrigation, mineral nutrition, and simplified tillage caused compensation of spring, winter and perennial weed species on plantation of faba bean ‘Titus'. Chenopodium album, Stellaria media, and Polygonum convolvulus predominated on studied plots. ...
