“…The increased yields were about 68% by NPK (S1) and 55% by N + ST (S2) higher in comparison with non-fertilized treatment. Obtaining the highest yields after using nitrogen in mineral forms confirm Cossani et al (2009), who achieved 4.5 t/ha of barley grain after the application of 80 kg N/ha and by CanteroMartinéz et al (2003), who obtained, in a 3 year experiment, an average yield of 4.3 t/ha after an annual dose of 75 kg N/ha. The effect of treatment on grain yield was highly significant at both sites: S1 (df = 5; F = 11.833; P < 0.05), S2 (df = 5; F = 9.532; P < 0.05), differences in post-hoc test are in Tables 2 and 3.…”

The aim of this study was to evaluate nitrogen (N) efficiency from different organic and mineral fertilizers applied to the spring barley. Dry matter yield, N content and N uptake of spring barley from 16 years of experiments at two sites in the Czech Republic with different soil and climatic conditions were analyzed. For assessing of nitrogen efficiency nitrogen utilization efficiency (NUtE, kg/kg), recovery efficiency of applied N (%), agronomic efficiency of applied N (kg/kg) and summary N balances (ΣΔN, kg/ha) were observed. Six fertilization treatments were utilized: no fertilization (control); sewage sludge; farmyard manure (FYM); N in mineral fertilizers (N); NPK in mineral fertilizers (NPK) and N in mineral fertilizers + straw (N + ST). Yields were about 68% higher at NPK (S1 site) and 55% at N + ST (S2 site) in comparison with control. The highest NUtE was recorded at both locations after application of FYM. Higher NUtE from mineral fertilizers was obtained at low productive S1 site. At both sites a trend of decreasing ΣΔN over time was observed. At both sites a trend of decreasing negative N balance was observed. At lower productive site the decline of N balance was minimized for mineral fertilizers treatments in last experimental years. At higher productive site the differences between treatments with mineral nitrogen and control were lower and the decline of N balance continued over all 16 years of experiment duration.

“…This could be ascribed to differences in (i) flowering time, (ii) grain-filling duration and/or (iii) the grain-drying period comprised from physiological maturity to the time grains reach the commercial moisture values (14%). Literature showed that flowering time is generally earlier in barley than in wheat (Fischer and Wood, 1979;Miralles and Richards, 2000;Cossani et al, 2009Cossani et al, , 2011. For the grain-filling period, the scenario is less certain: there are studies where barley grain filling was sometimes shorter than (López-Castañeda and Richards, 1994;Ugarte et al, 2007), or similar to (Fischer and Wood, 1979;Lingle and Chevalier, 1985;Ugarte et al, 2007) that of wheat.…”

“…Calviño et al (2003) quantified soybean yield reductions of 56 kg ha −1 per day of sowing delay, highlighting the importance of advancing the winter crop harvest in this double-cropping system. Barley could therefore be better than wheat for this system as there is evidence that it matures earlier (Fischer and Wood, 1979;López-Castañeda and Richards, 1994;Cossani et al, 2009Cossani et al, , 2011. This could be ascribed to differences in (i) flowering time, (ii) grain-filling duration and/or (iii) the grain-drying period comprised from physiological maturity to the time grains reach the commercial moisture values (14%).…”

a b s t r a c t Double-cropping using the wheat-soybean sequence is a common practice in Argentina to promote the intensification of crops within rotations. However, the late release of the fields by a delayed harvest time in wheat determines soybean yield penalizations. In this context, barley could represent a better option than wheat preceding soybean in the crop rotation since there is some evidence that finishes its cycle earlier than wheat. However, it is not clear which period of barley shortens crop cycle allowing an earlier field release than wheat. The objectives of this study were to compare wheat and barley in terms of (i) field release and (ii) grain weight determination through the analysis of their physiological mechanisms. Field experiments during two consecutive growing seasons testing five different environments (three sowing dates in 2007 and two in 2008) were carried out to analyze the duration of different ontogenic periods and the attributes (dry matter and water dynamics) determining grain weight during the grainfilling period in wheat and barley. Early flowering time was the main cause of the early field release by barley as the grain filling and drying period were similar in both species. A strong relationship was found between dry matter and water dynamics in both species. Barley reached a higher maximum water content than wheat and also achieved physiological maturity with higher moisture concentration than wheat (48% and 39%, respectively). Barley showed a slight increase in grain weight, respect to wheat, due to a source:sink ratio enhancement (4% and 9% for wheat and barley, respectively). These data show an opposite response to that of Mediterranean, Australian and UK environments, where barley was under stronger sink limitation than wheat during the grain-filling period.

“…Our farmers use around three times more pesticides compared to Finnish farmers. An experimental study determined in Agramunt (NE Spain) that application of 40 kg N lead to 4.5 and 6.3 ton/ha of barley yield under rain-fed and irrigated conditions, respectively (Cossani et al, 2009). This shows that our farmers apply much more N in their farms.…”

Current intensive grain crops production is often associated with environmental burdens. However, very few studies deal with the environmental performance of both current and alternative systems of barley production. This study was undertaken to evaluate energy consumption and environmental impacts of irrigated and rain-fed barley production. Additionally, three alternative scenarios were examined for irrigated barley fields including conservation tillage and biomass utilization policies. The findings showed that around 25 GJ/ha energy is needed in order to produce 2300 kg/ha irrigated barley and 13 GJ/ha for 1100 kg/ha rain-fed barley. Life cycle assessment (LCA) results indicated that irrigated farms had more environmental impacts than rain-fed farms. Electricity generation and consumption had the highest effect on the abiotic depletion potential, human toxicity potential, freshwater and marine aquatic ecotoxicity potential. However, alternative scenarios revealed that using soil conservation tillage systems and biomass consumption vs. gas for electricity generation at power plants can significantly mitigate environmental impacts of irrigated barley production similar to the rain-fed conditions while higher yield is obtained.Additional keywords: Hordeum vulgare L.; energy use efficiency; energy productivity; global warming potential.
