“…No differences of grain N concentrations were found between years although plants were exposed to different climatic conditions during grain filling and ripening; this is in contrast to findings for chickpea (Neugschwandtner et al 2015b) and pea (Neugschwandtner and Kaul 2015), which had higher grain N concentrations in a drier year. In accordance with the two previously mentioned papers, N concentrations in straw were higher in the dry year, as drought decreases grain yield and N remobilization from vegetative plant parts to the grain (Ercoli et al 2008).…”

Introducing autumn-sown legumes into Central European farming systems could be beneficial for addressing two challenges for European agriculture, i.e., the substantial deficit of protein sources for livestock and expected changes in agroclimatic conditions. Therefore, a two-year field experiment was conucted under Pannonian climate conditions in eastern Austria to assess nitrogen (N) yield and N fixation of several winter faba bean varieties from different European countries as compared to a spring faba bean. Winter wheat was used as a reference crop for estimating atmospheric N fixation. Winter faba beans were susceptible to frost damage especially in the harder of the two winters. Winter faba bean varieties could not achieve a higher grain yield and a higher grain N yield than the spring faba bean but had a higher grain N concentration (except for one variety). Grain yield and grain N yield of faba beans were severely impaired by drought in one year (with a mean of varieties of 8.3 g N m −2 , winter wheat: 6.4 g N m −2 ); in the other year, grain N yield of faba beans considerably surpassed that of winter wheat (with a mean of varieties of 21.5 g N m −2 , winter wheat: 8.8 g N m −2 ). After harvest, faba beans left higher nitrate residues in the soil, especially in the subsoil, and higher amounts of N in above-ground residues compared to winter wheat. Faba beans showed high N fixation under optimum conditions (with a mean of varieties of 21.9 g N m −2 ) whereas drought considerably impaired N fixation (with a mean of varieties of 6.3 g N m −2 ; with no differences between autumn-and spring-sown faba beans). In conclusion, growing winter faba bean varieties in eastern Austria did not result in higher grain yield, grain N yield, and N fixation compared to growing a spring faba bean.

“…In the present study, LER was up to 1.13 which indicates that resources were ultimately used up to 13% more efficiently for DM production, whereas LERN was up to 1.33 which means that intercrops can increase the use of N sources by up to 33%. These results are in agreement with other studies which showed LERN values for cereal–legume intercrops >1 (Bedoussac & Justes, ; Hauggaard‐Nielsen et al., ; Monti et al., ; Neugschwandtner & Kaul, ). Furthermore, the advantage of the intercrop compared with the monocrop for N acquisition has been observed to be greater than that for biomass production (Bedoussac & Justes, ).…”

“…In particular, red pea:oat 60:40 was better than red pea:oat 80:20, followed by red pea:wheat 60:40 and red pea:wheat 80:20. A greater share of red pea biomass in the intercrops compared with the other intercropping treatments can explain the high N use complementarity found in red pea:oat 60:40 treatment (Bedoussac & Justes, ; Monti et al., ; Neugschwandtner & Kaul, ). Therefore, high LERN values are important for increasing the ecological role of intercropping (through the use of legumes) as a sustainable way to increase N into a low‐input farming systems.…”

Red pea–cereal intercropping could provide animal feed with agronomic and economic advantages. The growth rate, forage yield, quality, interspecific competition and financial outcome of intercrops of red pea (Lathyrus cicera L.) with wheat (Triticum aestivum L.) and oat (Avena sativa L.) in two different seeding ratios (60:40, 80:20) were estimated. Growth rate of species was lower in the intercrops than in monocrops, especially in red pea–oat intercrops due to the strong competitive ability of oat. Red pea–oat intercrop of 60:40 produced the highest biomass (10.83 Mg/ha) and crude protein yield (1,116 kg/ha). Land equivalent ratio (LER) values were greater for the red pea with wheat (1.13) and oat 60:40 (1.09) indicating an advantage of intercropping in terms of dry‐matter (DM) yield, while red pea:oat 60:40 ranked first for LER for nitrogen yield. Aggressivity and partial actual yield loss indicated cereals as the dominant species. The highest monetary advantage index was recorded for the red pea:wheat 60:40 and the highest intercropping advantage value was recorded for the red pea:oat 80:20. In conclusion, most intercrops of red pea with wheat and oat showed significant advantages relative to their monocrops due to better DM production, resource‐use efficiency and economics under low‐input farming.

“…0% -pure stand of pea; 100% -pure stand of wheat, barley or oats pea. The most competitive is oats and wheat, and the less is barley (Neugschwandtner and Kaul 2015). In the experiment, in stand with barley, the proportion of pea seeds in the mixture was about 30% greater than its seeding ratio.…”

The effect of mineral nitrogen (N) nutrition on seed production and acquisition of 15 N from fertilizers by components of cereal-pea mixtures was investigated. Yields of wheat-pea and oats-pea mixtures raised together with the increase of cereals percentage in the pot, and higher seed yields of mixture with barley was affected by a larger share of pea plants. The percentage of nitrogen derived from fertilizers was significantly higher in cereals as compared with pea. Pea accumulated the greatest quantity of nitrogen from fertilizers in straw and roots, and cereals translocated 15 N mainly to ears -grain and glumes with rachis. The percentage of 15 N in seeds of pea amounted to 15% on the average, and in grain of cereals -54% to 60% of the total N taken up.
