The Biology And Ecology Of The Bromegrass Seed Midge In Nebraska, E. L. Nieman, G. R. Manglitz Nov 1972

The Biology And Ecology Of The Bromegrass Seed Midge In Nebraska, E. L. Nieman, G. R. Manglitz

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

These studies indicate that smooth bromegrass, Bromus inermis Leyss, is the only host of the bromegrass seed midge, Stenodiplosis bromicola Marikovskiy and Agafonova, in Nebraska. The midge did not infest two common annual brome species under field conditions. The midge has been collected from all counties surveyed in Nebraska and seems to be widely distributed throughout the midwestern states. An apparently undescribed species of Tetrastichus (Hymenoptera: Eulophiclae) was observed to parasitize all stages of the bromegrass seed midge. Parasitism rates greater than 90% were observed. The parasite larvae do not kill the midge until damage to the bromegrass floret has …


Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud Nov 1957

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …


Effect Of Stubble Mulching On Number And Activity Of Earthworms, S. P. Teotia, F. L. Duley, T. M. Mccalla Sep 1950

Effect Of Stubble Mulching On Number And Activity Of Earthworms, S. P. Teotia, F. L. Duley, T. M. Mccalla

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A survey of earthworm population under different cropping systems was made under stubble mulch farming and where the residue was plowed under. The influence of earthworms on some of the important physical and biological properties of the soil was studied. Their role in the decomposition of crop residues was also determined.
