“…It is likely that the effects of fertilization on weed density may be sensitive to regional weed species composition. Previous studies have documented that fertilization can significantly affect weed growth and community composition directly through affecting the soil nutrient availability and indirectly through intensifying resource competition between crops and weeds (Blackshaw et al, 2003;Menalled et al, 2005;Yin et al, 2006;Poggio and Ghersa, 2011). Weed community composition also depends upon particular nutrient, in our experiment the weed communities favored by the P treatments (NP and NP + FYM) were mainly distributed in the negative direction, whereas those without P (control, N and NK) were mainly distributed in the positive direction (Fig.…”

“…However, Yin et al (2006) reported a decreased weed density due to the application of different nitrogen fertilizers. Similar results were found in the study of Carson and Peterson (1990) who found that the weed density is less influenced than the weed biomass within the field.…”

The weed suppressive ability of oilseed radish (Raphanus sativus var. oleiformis Pers.) cover crop is attributed to high competitiveness for resources and biochemical effects on weeds. The oilseed radish cover crop was sown in five treatments plus an untreated control over a period of five weeks before and three weeks after winter wheat harvest. Additionally, fertilization effects on oilseed radish biomass and weed suppression were measured. The highest biomass of the cover crop was observed 12 weeks after harvest (WAH) when the oilseed radish was sown one week after harvest (1 WAH) (2015) and five weeks before harvest (5 WBH) (2016). No differences of fertilization were observed concerning oilseed radish and weed biomass in 2015, whereby increased biomass was found after fertilization in 2016. The highest weed control efficacy of up to 83% and 90% was achieved in treatments 1 WAH (2015) and 5 WBH (2016) at 12 WAH. The early sowing of oilseed radish in winter wheat resulted in low germination and biomass yield within the field, due to low precipitation in 2015. Nevertheless, there is a high potential of early sown oilseed radish for higher weed control efficacy, which was demonstrated in 2016.

“…album. Studies conducted by Yin et al (2006) showed that higher application rates of mineral fertilizers most typically reduce the number and air dry weight of weeds. This finding was partly confirmed in this study, in which the application of the complete nitrogen fertilization rate contributed to a reduction of the weeds number (by 5.8%).…”

The aim of the conducted study was to assess the effect of two types of stubble catch crops (a mixture of legumes and white mustard) as well as varied nitrogen fertilization on weed infestation of a spring wheat stand depending on the adopted tillage system. Weed infestation assessed at the tillering phase of spring wheat showed the lowest number of weeds in direct sowing after the mixed legume catch crop. The next assessment of weed infestation performed at the flowering phase of spring wheat showed that the lowest number of weeds was found in direct sowing immediately after the catch crop of a mixture of legumes and white mustard for the complete nitrogen fertilization rate. The lowest weed dry weight was recorded in conventional tillage after a mixture of legumes for the complete nitrogen fertilization rate and after white mustard for a reduced nitrogen fertilization rate.
