| Abstract/Contents: | "A 24-yr-old permanent field trial on coarse sand (Orthic Haplohumod) under temperate coastal climate conditions was used to determine (i) the effect of introducing perennial ryegrass (Lolium perenne L.) as a catch crop on plots with a history of low input of organic matter, and (ii) the residual effect of long-term use of ryegrass as a catch crop on main crop yield and N uptake. The catch crop (8-10 kg ha⁻¹ ) was undersown in spring wheat (Triticum aestivum L.). From 1993 to 1996, four treatments were included: catch crop since 1968, catch crop since 1993, no catch crop, and catch crop until 1993. Each treatment was conducted at two previously established N rates (60 and 120 kg N ha⁻¹ yr⁻¹), which were subdivided into four new N rates (0, 60, 90, and 120 kg N ha⁻¹ yr⁻¹. Two years after introduction of the catch crop, yields were no longer different from yields with long-term previous catch crop use. The residual effect of long-term catch crop use on yield persisted for more than 4 yr. With previous long-term use of a catch crop compared with no previous use, N fertilization could be reduced by 15 or 27 kg N ha⁻¹ yr⁻¹ at the 60 or 120 kg N ha⁻¹ yr⁻¹ rate, respectively, without yield reductions. The experiment shows that the use of ryegrass as a catch crop has the potential to benefit main crop yield and soil fertility." |
