AB  - Scarce water resources severely limit maize (Zea mays L.) cultivation in the temperate regions
of northern Serbia. A two-year field experiment was conducted to investigate the effects of
irrigation and planting density on yield and water use efficiency in temperate climate under
sprinkler irrigation. The experiment included five irrigation treatments (full irrigated treatment – FIT; 80% FIT, 60% FIT, 40% FIT, and rainfed) and three planting densities (PD1: 54,900 plants ha–1
; PD2: 64,900 plants ha–1; PD3: 75,200 plants ha–1). There was increase in yield with the irrigation (1.05–80.00%) as compared to the rainfed crop. Results showed that decreasing irrigation rates resulted in a decrease in yield, crop water use efficiency (WUE), and irrigation water use efficiency (IWUE). Planting density had significant effects on yield, WUE, and IWUE which differed in both years. Increasing planting density gradually increased yield, WUE, and IWUE. For the pooled data, irrigation rate, planting density and their interaction was significant (P < 0.05). The highest two-year average yield, WUE, and IWUE were found for FIT-PD3 (14,612 kg ha–1), rainfed-PD2 (2.764 kg m–3), and 60% FITPD3 (2.356 kg m–3), respectively. The results revealed that irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop water needs. In addition, if water becomes a limiting factor, 80% FIT-PD3 with average yield loss of 15% would be the best agronomic practices for growing maize with a sprinkler irrigation system in a temperate climate of Serbia.

AB  - Land use in agriculture can alter the physical, chemical and biological properties of soils, but little is known how it affects the hydraulic properties of the fine-textured soils of lowland agroecosystems in continental climates. This research assesses the impact of long-term (>100 years) continuous use of natural meadows and arable land, after conversion of native mixed deciduous forests, on hydraulic properties such as water retention, pore-size distribution, saturated hydraulic conductivity, and bulk density. The research was conducted on Fluvic Phaeozems in the valley of the Kolubara River, western Serbia. Disturbed and undisturbed soil samples from three different land use systems (forest, meadow, and arable land) and three different locations were collected at 0–15, 15–30, and 30–45 cm soil depth. Significant effects of different land uses were observed for bulk density, total porosity, macroporosity, mesoporosity, microporosity, air-filled porosity, field water capacity, plant available water capacity and saturated hydraulic conductivity at 0–15 cm soil depth, but a much smaller effect was observed at 15–30 cm. The water content estimated by the van Genuchten model was similar to the measured water content (R2 = 0.932–0.972). At 30–45 cm soil depth, land use only significantly affected a few of the examined variables. Dexter's soil physical quality index (S-index) also detected degradation of soil physical quality after conversion from forest to agroecosystems. In summary, the conversion of native forests into agricultural land tends to cause considerable change in the hydraulic properties and soil physical quality of fine-textured soils in lowland continental agroecosystems, which could have an adverse effect on crop yield and the environment. © 2022

AB  - Soil pore characteristics can have great impact on plant growt and environment. A study was conducted to evaluate the efects of different land use on porosity, pore size distribution (PSD) and soil water retention (SWR) of Fluvic Phaeozem in the Kolubara River valley, Serbia. The land use treatments included: natural forest, native meadow, and arable land managed in the same way for more than 100 years. Disturbed and intact soil samples were collected from three soil profiles at each of the three different land use types from depths of 0–15, 15–30 and 30–45 cm. The capillary rise equation was used to estimate effective pore sizes from water retention measurements. Pressure cells are used to mesure water retention in the water potential range from –33 to –1500 kPa. The bulk density (BD) was significantly (P < 0.05) larger for meadow (1.48–1.49 g cm–3) and arable land (1.28–1.42 g cm–3) than forest (0.99–1.29 g cm–3) at the top 30 cm of soil. There was no significant difference in BD between meadow and arable land in the subsurface soil layer (15–30 cm). Depending upon the increases in BD and disruption of pores by mowing and tillage management, total porosity decreased accordingly in meadow and arable land. Land use had significant effect on PSD. Volume of macropores (> 30 μm) were significantly higher for forest (10.93–16.19%) than meadow (4.77–5.74%) and arable (4.83–7.81%) land for 0–30 cm soil layer. Among the diferent land use types, forest and arable land had significantly higher mesopores (30–3 μm) volume compared with meadow. Mowing and tillage management significantly decreased volume of micropores < 3 μm diameter size at the 0–30 cm soil depth. The results showed that in the 0–0.15 m and 0.15–0.30 m depth soil layers, forest soils showed a significantly higher the available water capacity compared to meadow and arable lands. The S-index also detected clear differences among land uses. In this study, the soil water retention data are well described by the van Genuchten model. In conclusion, our results showed that total porosity, PSD, and moisture retention significantly changed because of the different management systems in the top 30 cm of soil, which can potentially influence crop yields and ecosystem function
