Osmia Spp. Reared In Artificial Nesting Sites In A Backyard Environment, R. L. Wilson, C. A. Abel, S. G. Mcclurg
Journal of the Iowa Academy of Science: JIAS
Controlled pollination in field cages is used at the United States Department of Agriculture - Agricultural Research Service North Central Regional Plane Introduction Station (NCRPIS) for seed increase of several plane species. Honey bees, Apis mellifera L., have been used almost exclusively for several years. Recently we began investigating other pollinating insects for controlled pollination. 0smia cornifrons (Radoszkowski), a solitary bee imported from Japan, has been an excellent early-season pollinator. We placed domiciles of these bees in backyards of the NCRPIS staff to aid us in providing adequate numbers of bees for use in field cages the following growing season. …
Distribution And Persistence Of Phyllachora Species On Poaceae In Iowa, A. C. Gabel, L. H. Tiffany
Distribution And Persistence Of Phyllachora Species On Poaceae In Iowa, A. C. Gabel, L. H. Tiffany
Journal of the Iowa Academy of Science: JIAS
Phytlachora spp. on Poaceae were collected to determine species present, grass hosts and distribution in Iowa. From 1959-1996 the fungus was collected 240 times from 67 different sites in 35 counties. Seven species of Phytlachora were collected on 25 species from 13 genera of grasses. P. graminis was collected 89 times from 43 sites on four species of Agropyron, two species of Calamagrostis, three species of Elymus, Hystrix patula, Panicum virgatum, and Setaria glauca. Seventy-two specimens of P. luteo-maculata on Andropogon gerardii or Schiziichyrium scoparium were collected from 30 sites. The study included 20 collections of P. cynodontis on Bouteloua …

Comparing Three Bee Species For Controlled Pollination Of Selected Brassicaceae, R. L. Wilson, C. A. Abel, R. L. Luhman
Comparing Three Bee Species For Controlled Pollination Of Selected Brassicaceae, R. L. Wilson, C. A. Abel, R. L. Luhman
Journal of the Iowa Academy of Science: JIAS
Pollination of species of Brassicaceae for seed increase at the USDA-ARS North Central Regional Plant Introduction Station (NCRPIS) has been accomplished for several years by using nucleus hives of honey bees, Apis mellifera L., in field cages. Brassicaceae are cool season crops that need pollination from late April to early June in the north temperate zone. Overwintered hives of honey bees need time to strengthen (i.e., increase their numbers) and thus it is difficult to make enough nuclei to meet our early season pollinations needs. Purchasmg package bees from suppliers in the southern U.S. is an expensive alternative. In this …
Planting Method And Fertilization Timing Effects On Ridge-Till Corn, Keith A. Kohler, Mohammadreza Ghaffarzadeh, Richard M. Cruse
Planting Method And Fertilization Timing Effects On Ridge-Till Corn, Keith A. Kohler, Mohammadreza Ghaffarzadeh, Richard M. Cruse
Journal of the Iowa Academy of Science: JIAS
Fertilizer application technology has improved fertilizer use efficiency in ridge-till systems, but little work on planting methods and application timing within these systems has been done. A study was conducted to evaluate corn (Zea mays 1.) response to injected nitrogen (N) fertilizer applied to different planting methods at common application times. The performance of the late spring soil nitrate and the basal stalk nitrate tests was examined within these systems. A continuous corn and a corn-soybean [Glycine max (1) Merr.] rotation were used in 1989-1991 at two Iowa locations on Nicolett and Monona series soils, line-loamy, mixed, mesic Typic …
The Species Richness Of Birds Visiting A Yard Is Influenced By The Feeders/Seeds Present, David Joseph Horn
The Species Richness Of Birds Visiting A Yard Is Influenced By The Feeders/Seeds Present, David Joseph Horn
Journal of the Iowa Academy of Science: JIAS
Although seed preferences of species that visit bird feeders have been well documented, we know little about feeder/seed combinations most appropriate for attracting highest species richness or increasing abundance of individual species. I studied how the species composition of birds visiting a feeding station was influenced by addition of feeders filled with mixed seed, thistle, and suet in a yard that previously contained only a feeder with sunflower seeds. Addition of a seed mixture consisting of hulled sunflower, hulled peanuts, hulled millet, and hulled "tree" nuts in an elevated platform feeder increased species richness and total number of birds visiting …
Chlorophyll Meter Assessments Of Corn Response To Nitrogen Management Practices, M. M. Siambi, D. L. Karlen, R. M. Shibles
Chlorophyll Meter Assessments Of Corn Response To Nitrogen Management Practices, M. M. Siambi, D. L. Karlen, R. M. Shibles
Journal of the Iowa Academy of Science: JIAS
Environmentally sound nitrogen (N) management is necessary to simultaneously achieve high crop yields and protect surface and groundwater quality. We evaluated a hand-held chlorophyll meter as a diagnostic tool for improving management for corn (Zea mays L.). Five N fertilizer rates (0, 67, 134, 201 and 280 kg N ha-1) were evaluated in one study, and in a second study, the meter was used to evaluate the N status of corn plants grown under varying tillage (chisel plow vs no-till), crop rotation (continuous corn vs corn-soybean [Glycine max (L.) Merr.]), and N management treatments. Meter readings were …
