Abstract
THE EFFECTS OF SOWING TIME AND OF NITROGEN ON PEAS, PISUM SATIVUM AND ON PEA ROOT EELWORM, HETERODERA GOETTINGIANA LIEBSCHER BY F. MORIARTY School of Agriculture, University of Cambridge, England In two experiments the effect of sowing time on eelworm multiplication was variable, and in one experiment the effect of nitrogen was negligible. The relationship between yield and initial eelworm density was also variable, probably because peas, unlike many susceptible hosts, are not stimulated by larval invasion to form new lateral roots, so that at times of water shortage, even with a low eelworm density, absorption of soil solution is
