“…In these growing areas, the conventional cropping system generally adopted by farmers to feed biogas plants involves the insertion of maize, chopped at the dough stage, into a double cropping system in combination with a winter cereal, such as triticale (× Triticosecale Wittmack) harvested at the early dough stage [19]. In these production situations, triticale allows a satisfactory biomass to be obtained, in terms of quantity and quality, thus providing a good response to fertilization with organic N and catching nitrogen leaching from the soil during autumn and winter [9,20,21]. Garuti et al [22] reported that the cellulose content and degradability mainly affect the methane production of different triticale cultivars.…”

The biogas supply chain requires a correct combination of crops to maximize the methane yield per hectare. Field trials were carried out in North Italy over three growing seasons, according to a factorial combination of four cropping systems (maize as a sole-crop or after hybrid barley, triticale and wheat) and two maize plant densities (standard, 7.5 plants m−2 and high, 10 plants m−2) with the plants harvested as whole-crop silage. The specific methane production per ton was measured through the biochemical methane potential (BMP) method, while the methane yield per hectare was calculated on the basis of the BMP results and considering the biomass yield. The average methane yield of wheat resulted to be equal to 4550 Nm3 ha−1, and +17% and +28% higher than triticale and barley, respectively, according to the biomass yield. A delay in maize sowing reduced the yield potential of this crop; the biomass of maize grown after barley, triticale and wheat was 20%, 33% and 47% lower, respectively, than maize cultivated as a single crop. The high plant population increased the biomass yield in the sole-crop maize (+23%) and in the maize grown after barley (+20%), compared to the standard density. The highest biomass (32 t ha−1 DM) and methane yield (9971 Nm3 ha−1) within the cropping systems were obtained for barley followed by maize at a high plant density. This cropping system increased the methane yield by 46% and 18%, respectively, compared to the sole-crop maize or maize after triticale at a standard density. The smaller amount of available solar radiation, resulting from the later sowing of maize, reduced the advantage related to the application of a high plant density.

“…Previous research on the effects of pig slurry application on soil HM (Provolo et al, 2018) or on other aspects, such as N efficiency (Bosch-Serra et al 2015) and N uptake and losses (Ovejero et al 2016), has been conducted over a relatively low number of cropping seasons. However, research has studied acid or neutral soils (Veiga et al 2012;Tiecher et al 2013;Oliveira et al 2014;Qaswar et al 2020), irrigated systems (Martínez et al 2017), or it has developed under greenhouse conditions (Montaghian and Hosseinpur 2015;Provolo et al 2018).…”

Intensive pig farming produces large amounts of slurry, which is applied to agricultural soils as fertilizer. A 7-year field study was performed to check the effect of pig slurry on soil properties and on the accumulation of some essential nutrients and heavy metals in a calcareous silty-loam soil (0–0.3 m) and in barley (Hordeum vulgare L.) plants in two cropping seasons with contrasting amounts of rainfall. Five fertilization treatments, control (no N applied), mineral fertilizer (90 kg N ha−1), and different N doses of pig slurry (146, 281, 534 kg N ha−1), were applied at sowing of a barley crop. Organic carbon, available P and K, and total P in soil increased with slurry dose. No differences were found in Co, Cr, Fe, Mn, Ni, and Pb soil concentrations. Slurries increased Cu, Mn, and Zn extractions and plant concentrations of P in straw and Zn in grain. However, the lowest slurry rate was able to maintain the highest grain yields while improving fertility. The results of this research study support the sustainability of pig slurry fertilization at appropriate rates in relation to soil chemical quality.

“…Double‐annual cropping strategies for forage production have been implemented by farmers in some areas of southern Europe (Grignani, Zavattaro, Sacco, & Monaco, 2007; Maresma, Martinez‐Casanovas, Santiveri, & Lloveras, 2019; Ovejero et al., 2016; Raphalen, 1980; Trindade, Coutinho, Jarvis, & Moreira, 2001). However, some of these areas are dry, such as the Ebro Valley, and farmers can barely grow a single crop each year without irrigation (Lloveras & Cabases, 2014).…”

Double‐annual cropping systems can increase the productivity of farmland and simultaneously confer environmental benefits, but the optimal combination of crops and cultivation strategies is likely to be region‐specific. For instance, because of the low precipitation and specially in the summer, in Mediterranean environments irrigation is usually needed to grow two crops within a year. In the present 3‐year study, a double‐annual cropping system for forage production (winter crops and maize) was evaluated under irrigated Mediterranean conditions. Eight winter varieties (including barley, Italian ryegrass, oats, oats plus vetch, triticale and wheat) were harvested in April or May. Maize was sown few days after each harvest time. The average forage yield of the winter crops harvested in April was 6.3 Mg/ha dry matter (DM), with an average crude protein (CP) content of 16.4% and a digestibility of 63.4%. The average yield was significantly higher for the crops harvested in May (10.0 Mg/ha DM) but with lower forage quality and digestibility (10.8% CP and 52.8%, respectively digestibility). Maize yields were higher (27.6 Mg/ha DM) in the May than in the April (25.1 Mg/ha DM) sowing date, while the forage quality was similar (7.1% CP, 64.5% digestibility). The total annual forage yield was 31.3 Mg/ha DM for April harvest/sowing date (weighted quality = 8.7% CP, 64.9% digestibility) and 37.6 Mg/ha DM for May harvest/sowing date (weighted quality = 8.2% CP, 60.5% digestibility). Therefore, under conditions of the present research in Mediterranean environments, the May harvest/sowing date was the most convenient strategy to produce forage in double‐annual cropping systems and specially the triticale–maize rotation.
