摘要

New high yielding early maturing cultivars of lupins have been introduced in north-west Europe as grain protein crops in crop rotations. This paper reports on a comparative Study Of lupins with peas and oats, and of their effect on yield of subsequent winter barley crops. These crops were given five levels of N under irrigated and non-irrigated conditions on sand and loam. Under rain fed conditions the grain yield of pea, oat and lupin varied between 24-36, 34-53 and 18-37 hkg DM ha(-1) respectively. Supplemental irrigation raised rain yield of oat to 50-60 hkg DM ha(-1), while grain yield in pea was not affected and grain yield in lupin in most cases decreased due to gray mould attack and excessive vegetative growth in the indeterminate lupin variety. Under rain fed conditions, the grain nitrogen content of pea, oat and lupin varied between 137-172, 61-80 and 189-226 kg N ha(-1), respectively, and was significantly higher in lupin as compared with pea. On sandy soil, similar low-root densities were found for pea, oat and lupin below 30 cm depth. On sand, at final harvest the residual soil-N of lupin and pea, as measured in a subsequent winter barley crop not Supplied with N fertilizer, was 15 and 8-10 kg N ha(-1) higher than in winter barley following oat, respectively. The nature of the probably more N-root residues of lupin is discussed. On loan, the residual N of lupin and pea was similar, 18-27 kg N ha(-1). Oil sand, Under rain fed conditions preceding lupin and pea as compared with oat, increased the barley grain yield at zero N-application 77 and 49%, respectively the effect of Input was significantly higher than that of pea until the highest N-level 120 kg N-application ha(-1). On loan under rain fed conditions preceding lupin and pea increased the barley grain yield at zero N-application by 36 and 62%. respectively, as compared with oat; at N-application >60 kg N ha(-1) the grain yield was similar after all three crops. For both soil types the same level of effect was found under irrigated conditions. Conclusiom: Supplemental irrigation might result in lower grain yield in lupin due to gray mould attack and excessive growth if indeterminate lupin varieties are used. Grain nitrogen yield of lupin is significantly higher than that of pea. On sand, the effect of lupin on the subsequent winter barley gain yield is significantly higher than that of pea, probably due to greater N-root nitrogen residues. On loam, lupin and pea have similar effects oil the subsequent winter barley crop
