Large DNA insert libraries in binary T-DNA vectors can assist in the isolation of the gene(s) under-lying a quantitative trait locus (QTL). Binary vectors facilitate the transfer of large-insert DNA fragments containing a QTL from E. coli to Agrobacterium sp. and then to plants. We constructed two soybean large-insert libraries from cv. Forrest in the pCLD04541 (V41) binary vector after partial digestion of genomic high-molecular-weight DNA with BamHI or HindIII. The libraries contain 76,800 clones with an average insert size of 125 kb, and therefore represent 9.5-fold haploid genome equivalents. Colony hybridization using a chloroplast-specific probe infers that …

Bean Leaf Beetle (Coleoptera: Chrysomelidae) Abundance In Soybean Fields Protected And Unprotected By Shelterbelts, Stephen D. Danielson, James R. Brandle, Laurie Hodges, P. Srinivas
Bean Leaf Beetle (Coleoptera: Chrysomelidae) Abundance In Soybean Fields Protected And Unprotected By Shelterbelts, Stephen D. Danielson, James R. Brandle, Laurie Hodges, P. Srinivas

The bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae), is a major insect pest of soybean in Nebraska and throughout much of the Midwest. This insect overwinters in the adult stage in litter in wooded areas such as shelterbelts. Historically, crop producers have been unsure of the merits of shelterbelts, especially if nearby crops are more likely to be infested by insect pests as a result. In this study, bean leaf beetle adults were sampled during the season by visually counting the number of beetles found on soybean plants early in the season and by sweep net sampling once plants …
Ec00-802 Soybean Basis Patterns From Selected Sites In Nebraska, Lynn Lutgen
Ec00-802 Soybean Basis Patterns From Selected Sites In Nebraska, Lynn Lutgen
University of Nebraska-Lincoln Extension: Historical Materials
The following publication contains soybean basis patterns for several towns in Nebraska. The basic price information was collected through surveys, newspaper, electronic media, etc. The listing includes towns that are representative of different geographic locations in Nebraska. The amount of data varies among locations. This publication will be updated each year by adding a year's data to each location which will allow the user to observe the changes in the basis patterns over time.
G00-1395 Soybean Seeding Rates, Roger Wesley Elmore, James E. Specht
G00-1395 Soybean Seeding Rates, Roger Wesley Elmore, James E. Specht

The soybean stand looked horrible late that May. The field had a good seed bed at planting, but rain after planting crusted the soil over the seed furrows. Rain was in the short-term forecast. All other row crops were planted and looked fine, but this field concerned the producer. Should the producer replant? Recommended soybean seeding rates, stand assessment and replanting rates based on Nebraska field research are addressed in this NebGuide.
Corn (Zea Mays L.) Yield Response To Nitrogen Fertilizer In Conventional And Alternative Rotations, M. M. Harbur, M. Ghaffarzadeh, R. M. Cruse
Corn (Zea Mays L.) Yield Response To Nitrogen Fertilizer In Conventional And Alternative Rotations, M. M. Harbur, M. Ghaffarzadeh, R. M. Cruse
Journal of the Iowa Academy of Science: JIAS
Nitrogen (N) fertilization recommendations are not available for corn in rotation with small grains or forages despite the possibility that the N response may differ from that of more conventional corn-soybean rotations. Rotations of corn with soybean (CS), corn with soybean and oat (CSO) and corn with soybean and an oat/berseem clover intercrop (CSOB) were established in 1991 and studied from 1993 through 1998 to determine the optimal N fertilization level for corn produced in each rotation. Corn in each rotation received NH4N03 applied at the rates of 0, 56, 112, or 168 kg N ha-1. Significant differences …
