| effects of interplanting flowering plants on the biological control of corn earworm (lepidoptera: noctuidae) and thrips (thysanoptera: thripidae) in sweet corn. | natural enemy exploitation of food resources and alternative hosts in noncrop vegetation has been shown to be an effective means of enhancing natural enemy populations in diversified agro-ecosystem. field trials were conducted in hawaii to examine effects of interplanting flowering plants on 1) parasitism of corn earworm, helicoverpa zea (boddie) eggs by trichogramma spp., and 2) abundance of orius spp. in relation to prey (h. zea eggs and thrips [primarily, frankliniella occidentalis (pergande) ... | 2016 | 26500338 |
| nutrient concentrations within and below root zones from applied chicken manure in selected hawaiian soils. | the objective of this study was to evaluate the effects of chicken manure (cm) application rates on nutrient concentrations within and below the root zone of sweet corn (zea mays l. subsp. mays) under hawaiian conditions. the research was conducted in leeward (poamoho) and windward (waimanalo) areas of oahu, hawaii, where contrasts exist in both climatic and soil conditions. suction cup were used to collect soil solutions from 30 and 60 cm depths. soil solutions were collected six times during t ... | 2009 | 20183097 |
| biomass and nutrient concentration of sweet corn roots and shoots under organic amendments application. | two field experiments were conducted at the waimanalo research station on the island of o'ahu, hawaii to study the effect of chicken (cm) and dairy (dm) manures on biomass and nutrient concentration in sweet corn roots and shoots. sweet corn (super sweet 10, zea mays l. subsp. mays) was grown for two consecutive growing seasons under four rates of application (0, 168, 337, and 672 kg ha(-1) total n equivalent) and one time (ota) or two time (tta) applications of organic manure types and rates. t ... | 2009 | 20183085 |
