Various species of insect pests were identified attacking citrus. The major leaf feeders were the scale insects which infested a mean of 13 % of the trees, the leaf miners (8.7 %), aphids (10.6 %) and the swallowtail butterfly larvae (23.7 %). Termites damaged the exposed parts of roots and the woody structure of some citrus trees, and was suspected to have positively influenced the spread of Phytophthora-induced diseases (r = 0.75; P<0.01; n = 10). Fruit drop caused by fruit piercing insects occurred in 30 to 90 % of sampled trees per farm. Major citrus diseases observed included the citrus tristeza disease, foot rot, brown rot and leaf spot diseases. Farmers' pest/disease management practices were ineffective. Factors that contributed to unsatisfactory control were highlighted. \u0000Keywords: Citrus, fruit drop, insect pests, die-back, pest-disease complex, intercropping","PeriodicalId":185766,"journal":{"name":"Nigerian Journal of Horticultural Science","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131672892","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}

The 2 x 4 factorial experiment was laid out in a randomized complete block design and replicated thrice. Tillage method had significant (P < 0.05) effects on the performance of C. argentea. The crops on raised seedbed produced better seedling vigour than those on no tillage. Higher yield of up to 15 t ha-1 (fresh weight) was obtained from raised seedbed compared to 1.1 t ha-1 (fresh weight) obtained from no tillage. Crops raised on bed at a density of 4,000,000 plants ha-1 produced the highest yield, while the least yield was obtained from those sown on no tillage at a density of 250,000 plants ha-1. Generally, there was no significant interaction between seedbed type and crop density. Crops on raised seedbed outyielded those on no tillage. Also the higher the density, the more the cumulative biomass yields. Seedling vigour and edible yield however improved with decreasing density with 444,444 plant ha-1 producing the optimum value. \u0000Keywords: No tillage, seedbed, crop density, Celosia argentea, leaf area index, marketable yield, edible yield","PeriodicalId":185766,"journal":{"name":"Nigerian Journal of Horticultural Science","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128691243","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}
