A taxonomically difficult set of <em>Stylosanthes</em> (Leguminosae) accessions is subjected to classification, a minimum spanning tree, and a two-neighbour network. It is then subjected to a novel multiple-nearest-neighbour approach (program NEBALL) which provides a more detailed and exact summary of the configuration; this is validated by appeal to phytochemical, provenance and performance data. The results suggest that, providing the assumptions implicit in the model are met, the new technique may well be the most powerful yet available for the study of genetic resources data.</p></div>","PeriodicalId":100066,"journal":{"name":"Agro-Ecosystems","volume":"8 3","pages":"Pages 231-245"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3746(83)90006-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88229322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phorate was applied onto the soil and leached with water under ponded and controlled infiltration conditions. Phorate and water distribution profiles were determined by destructive sampling at two stages: (1) immediately following infiltration and (2) after matching total infiltration, redistribution and evaporation time for two water-application rates. Regardless of the initial soil water content, just after the termination of infiltration, phorate was displaced more efficiently and its concentration peak formed at deeper depth with the slower than with the faster application rate. Following redistribution, this trend was reversed. Phorate movement was also found to be dependent on the initial soil water content. The higher the initial soil water content, the deeper and more complete was the displacement of phorate during infiltration and redistribution.</p></div>","PeriodicalId":100066,"journal":{"name":"Agro-Ecosystems","volume":"8 3","pages":"Pages 259-263"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3746(83)90009-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88467495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
