Austrian winter field peas [ Pisum sativum spp. arvense (L.) Poir.] are usually planted in the fall on 18 cm row spacings. Winter damage, cold soils, and soil‐borne diseases reduce vigor of fall planted peas more than spring planted peas. Spring planted peas escape winter damage and cold soil problems and have more resistance to some of the soil borne diseases. This study was undertaken at two locations to determine the influence of row spacings on yield of spring planted Austrian winter field pea. Row spacings were 18 cm between rows, 36 cm between rows, and alternating spacings of 18 and 36 cm between rows. ‘Fenn’ peas planted on 18 cm row spacings averaged 29 and 43% more seed than peas planted on 18‐36‐18 and 36 cm row spacings, respectively. Weed competition did not significantly influence seed yield of spring planted Fenn peas at any row spacing or location. Vine dry weight of peas planted on 18 cm rowspacings at mid‐season and harvest was significantly higher than vine dry weight of peas planted at other rowspacings, regardless of weed control treatments. Vine dry weight at harvest was also highest for peas that had been weeded regardless of rowspacing. Spring planted Austrian winter peas yielded about one‐third to one‐half as much as fall planted winter peas in independent studies.
