“…Another noticeable point was lower ADF and NDF values in the dry year of 2010 compared to other 2 years. Our results disagree with decline in the ADF and NDF contents in barley-legume intercrops relative to the respective monocrops observed in central Alberta (Aasen et al, 2004;Strydhorst et al, 2008).…”

“…This shows that pea + cereal intercrops can improve quality of silage or green feed over the monocrop cereals. Increases in forage CP from pea + cereal intercrops over monocrops have been earlier reported for barley and oats in northern Great plains (Carr et al, 2004), and over monocrop barley in central Alberta (Izaurralde et al, 1990;Aasen et al, 2004;Strydhorst et al, 2008).…”

Spring barley (Hordeum vulgare L.), oat (Avena sativa L.) and triticale (x Triticosecale Wittmack) monocrops and their intercrops with two forage varieties (40-10 and Tucker) and one seed variety (Cooper) peas (Pisum sativum L.) were evaluated for forage production, nutrition quality and suitability in the beef cattle diet. Pea + cereal intercrops were compared to respective cereal monocrops in 2009, 2010 and 2011. Plant height of cereals tended to be reduced in intercrops compared to respective monocrops. Taller 40-10 forage type pea tended to cause lodging in 2009 and 2011, not observed with other pea varieties. Fresh forage of pea + cereal intercrops had higher moisture than respective cereal monocrops. Fourteen of the 18 intercrops had less dry matter yield (DMY) than respective cereal monocrops. Shorter Tucker pea had less negative impact on DMY than taller 40-10 pea. Treatments with barley had lower DMY than respective oat and triticale systems. Intercrops improved forage crude protein (CP) content over the respective monocrops, which was enough to overcome the DMY penalty and produce more CP yield than their monocrops. The forage Ca and Mg contents were improved by intercrops over their monocrops, and they were greater with 40-10 pea than other pea varieties and with barley than oat or triticale. The forage P content also tended to be higher in intercrops than corresponding monocrops, without a consistent effect of cereal type or pea variety. The forage K and S contents were not consistently influenced by the cereal types, pea varieties or intercrops. Forage Na content was greater from oat than respective barley and triticale treatments. The monocrops and intercrops had similar forage Cu content, and treatments with barley had more Cu than with oat or triticale. Forage Zn content tended to be intercrops > monocrops; and barley > triticale > oat. Treatments had no influence on the forage Fe and Mn contents. Levels of acid (ADF) and neutral (NDF) detergent fibres in the forage were similar for the corresponding intercrops and monocrops, and greater for oat than barley or triticale treatments. Some of the intercrops improved total digestible nutrients (TDN) content in forage over their monocrops. Monocrop of oat had less TDN than barley or triticale. Drought reduced the ADF, NDF and TDN contents. The forage NE L , NE M and NE G as well as RFV and NFC showed similar trend as the TDN. Overall, the tested pea + cereal intercrops did not increase DMY over the respective monocrops, but they indicated several nutritional quality benefits. These improvements present opportunities to substitute some grain or supplements in the beef cattle diet with better quality forage by intercrops.

Forage yield and biological nitrogen fixation of pea–cereal intercrops for hay production

et al. 2023

View full text Add to dashboard Cite

Intercropping forage pea (Pisum sativum L.) with barley (Hordeum vulgare L.) or oat (Avena sativa L.) is an alternative way of cropping to improve forage yield and quality for hay production compared to monocropping. A 2-year (2016-2017) field study was conducted at three sites in Saskatchewan, Canada, to evaluate forage production and biological nitrogen fixation (BNF) of pea-cereal intercrops in comparison to pea, barley, and oat monocrops with and without 60 kg N ha −1 fertilization. Barley and oat were dominant (p < 0.001) in the intercrop by accounting for 65%-92% of the total dry matter (DM) yield. Compared to the pea monocrops, pea-cereal intercrops significantly increased forage DM yield at Melfort (52%-73%), Saskatoon (68%-118%), and Swift Current (25%-69%). At Melfort, nitrogen (N) fertilization increased total forage DM yield (p = 0.003) of monocrops and intercrops but it reduced N fixation by 22%-63% (p < 0.01). At Swift Current site, N fixation was reduced by 35%-65% (p = 0.019) when N fertilizer was applied. The total amount of N fixation varied from 18 kg N ha −1 (Swift Current) to 59 kg N ha −1 (Melfort), whereas the N transfer rate ranged from 17% (pea:oat) to 43% (pea:barley) in the intercrops. This study indicates that intercropping forage pea with forage barley or oat increased forage DM yield and N fixation. Effect of N fertilization on BNF was site specific, reducing N fixation of pea at two of three sites in the study.
