The objective of this study was to evaluate variations in potato tuber yield with the selected land and soil characteristics including (i) topography (elevation and slope); (ii) geometry (horizontal coplanar geometry (HCP)and perpendicular coplanar geometry (PRP)); (iii) hydrology (volumetric moisture content; θv), and (iv) chemistry (phosphate, potash, organic carbon; organic carbon and pH). Analyses of the data collected across four potato fields, two each in Prince Edward Island and New Brunswick (NB), showed that the tuber yield negatively correlated with the field slope and positively correlated with most of the soil characteristics...

Regarding the increased surface runoff from production areas, wide-row crops grown on slopes are considered risk crops. By reducing the surface runoff, it is possible to mitigate the negative effects on both the soil and the plants and positively influence the subsequent production, e.g., after application of de-stoning before planting. During this research, the tied ridging method was applied during planting by a two-row planter in both central and tractor trail furrows in potato rows and on the slope of 8.8% compared to a control plot without this treatment. Rainfall and surface water runoff were monitored, and the crop yields were compared. During...

In this experiment, the response of winter oilseed rape cv. SY Alister F1 to diverse foliar fertilization was evaluated. Foliar fertilization with the preparation Insol 5 was applied at the following dates: control (without a foliar fertilizer); autumn; autumn + spring; autumn + twice spring; spring and twice spring. Each variant in which autumn foliar fertilization was carried out contributed to a significant increase in plant density before harvest. In turn, each variant with spring foliar fertilization significantly increased the number of pods per plant compared to the control. Variants with autumn + spring, autumn + twice-spring, and twice-spring...

The present study was carried out in 2016-2017 to assess the effect of subsoiling depth on the soil bulk density, stability of soil structure, soil physical properties and summer maize yield based on a field experiment started in 2015. Four tillage depths were studied: conventional tillage 25 cm (CT25); subsoiling tillage 30 cm (ST30); subsoiling tillage 35 cm (ST35) and subsoiling tillage 40 cm (ST40). The results showed that at the 20-50 cm depth ST

A field experiment was carried out in the years 2012-2018 in Poland in a split-plot design. The aim of the study was to determine the long-term effect of legumes as forecrops on the productivity of rotation with nitrogen fertilization. The rotation included: legumes + spring barley (SB), winter rape (WR), winter wheat (WW) and winter wheat. The study was conducted as a two-factorial field experiment with four replications. The present study showed that legumes as forecrops increased the yield of all after-harvest crops in rotation. Yielding of these crops also depended on nitrogen fertilization and position in the rotation. After comparison of the...

The aim of the study was to evaluate the amount of nitrogen taken up from air, mineral fertilizers and soil by yellow lupine (Lupinus luteus L.) and spring triticale (Triticosecale Wittm. ex A. Camus) in their intercropping cultivation. The factor examined in the experiment was percentage of yellow lupine seeds and spring triticale grain in sown mixtures: 100/0, 75/25, 50/50, 25/75 and 0/100, respectively. Yellow lupine yield was reduced by spring triticale when intercropped. In the yield of both plants the percentage share of spring triticale grain was larger and that of yellow lupine seed was smaller than in the sown mixture. Land...

Arbuscular mycorrhizal fungi (AMF) increase soil organic carbon (SOC) deposition via secretion of glomalin-related soil protein (GRSP) and modulation of plant carbon partition. Two exogenous AMF inocula (Rhizophagus irregularis and Glomus versiforme) were applied to the roots of Populus × canadensis seedlings grown in the unsterilized nursery soil. The diversity of fungal and bacterial communities was assessed by the polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) method, while the accumulation of GRSP and SOC content in 22.5 cm-deep soil was measured. The results indicated that two AMF...

Field and laboratory studies determined the effect of intercrop plants (rye, buckwheat, white mustard and sunflower) used in carrot cultivation on the occurrence of Clonostachys spp., Albifimbria spp., Trichoderma spp. and Penicillium spp. in the soil and their antagonistic activity. Rye and white mustard were the most effective in limiting the occurrence of soil-borne fungi. Those plants caused an increase of the population of the studied antagonistic fungi. Buckwheat and sunflower promoted the development of antagonists a little worse. The antagonistic activity of the aforementioned fungi was the highest after...
