In two glasshouse experiments, sugarbeet root dry weight, as a percentage of the maximum, decreased with preplanting populations of Heterodera schachtii according to an exponential equation with a tolerance limit.
“In two glasshouse experiments, relations between sugarbeet root dry weight (y, expressed as a percentage of the maximum dry root weight), and preplanting populations of Heterodera schachtii”
In a field experiment in the Imperial Valley, sugarbeet root yield decreased with preplanting population of Heterodera schachtii as y = 100 (0.99886)^(Pi) - 100.
“In a field experiment in the Imperial Valley the relation between root yield (y) and P(i) was y = 100 (0.99886)(P(i) ) - 100, and the tolerance limit was 100 eggs/100 g soil”
“Horizontal growth of seedling roots of Lepidium sativum L. cv. Curled is sensitive to white light with a photon flux density as low as 7.5 μEinsteins m−2 S−1”
“Delayed planting was accompanied by changes in leaf number, with a significant increase in leaf number at the middle planting dates, a decreasein the periods from planting to tassel emergence and mid-silk, and an increase in grain moisture at harvest”

“Delayed planting was accompanied by changes in leaf number”
“The increase density of the stroma, formation of fibrils, and general decreasein volume is probably the result of an increase dehydration of the chloroplasts brought on by permeability changes induced by the pollutants.”
“Yield losses of spring barley, Hordeum vulgare L., caused by feeding of the cereal leaf beetle (CLB), Oulema melanopus (L.), were determined by comparing yields of insecticide‐treated plots with CLB‐infested plots”
e1
“The CLB caused substantial grain losses in three field tests in Michigan in 1974 and 1975”
e2
“The average yield loss of seven susceptible barley cultivars in the three tests was 38% due to an estimated peak density of 1.6 larvae/stem”
“Black grass bugs (Labops hesperius) at a population density of 156 bugs per square meter did not affect herbage yields of intermediate wheatgrass but depressed seedhead production 56%”
e1
“They caused a small but significant increase in concentrations of crude protein and a slight decreasein cellular contents”
