Abstract
Aboveground yield and the production of senescent and dead tissue were measured in perennial [Lolium perenne] and Italian [L. multiflorum] ryegrasses, white [Trifolium repens] and red [Trifolium [T. pratense] clover and in mixtures of these species during 2 regrowth periods in late summer/early autumn. During the first 3 wk of regorwth, applied N approximately doubled yield of ryegrass without increasing the production of senescent and dead tissue. During the later stages of regrowth, in ryegrass and white clover, production of new tissue was approximately counterbalanced by senscence and death. Red clover grew vigorously during late summer to produce a tall, high-yielding crop which contained a relatively low proportion of senescent and dead tissue. Losses due to decomposition and other causes were extremely low in red clover during this period. During early autumn the growth of red clover was similar to that of white clover.This publication has 2 references indexed in Scilit:
