Stadler, L. J., "The Comparison of Ultra-Violet and X-ray Effects on Mutation," Cold Spring Harbor Symp. Quant. Biol., 9, 188-177 (1941). Stadler, L. J., and Uber, Fred M., "Genetic Effects of Ultra-Violet Radiation in Maize. IV. Comparison of Monochromata Radiations," Genetics, 27, 84-118 (1942). Stadler, L. J., and Roman, Herschel, "The Effect of X-rays upon Mutation of the Gene A in Maize," ...
Contemporary crop production faces dual challenges of increasing crop yield while simultaneously reducing greenhouse gas emission. An integrated evaluation of the mitigation potential of yield-scaled nitrous oxide (N2O) emission by adjusting cropping practices can benefit the innovation of climate smart cropping. This study conducted a meta-analysis to assess the impact of cropping systems and ...
To compare the soil water balance, yield and water use efficiency (WUE) of spring maize under different mulching types in the Loess Plateau, a 7-year field experiment was conducted in the Changwu region of the Loess Plateau. Three treatments were used in this experiment: straw mulch (SM), plastic film mulch (PM) and conventional covering without mulch (CK). Results show that the soil water chan...
A summer-planted crop of alyceelover significantly (P < 0.05) increased the soil abundance of Meloidogyne arenaria race 2 juveniles by 3.7-fold when measured in the following spring. Maize, sorghum, and soybean had no significant effects on residual nematode numbers over the same period. Summer plantings of aeschynomene, cotton, hairy indigo, tespedeza, millet, peanut, and sorghum-sudangrass we...
The potential effects of future climate change were investigated, corresponding to a doubling of atmospheric CO2 from 350 to 700 ppm, on agricultural production of four different cropping systems at two Italian locations, Modena and Foggia. Climate change scenarios, derived from two general circulation models (GCMs), were used as weather input to a soil-plant growth simulator, CropSyst. This mo...
We investigated potential use of prairie as a Midwestern cellulosic feedstock by conducting a 9 ha side-by-side comparison of maizeand prairie-based systems on fertile soils in Boone County Iowa, USA. Investigated systems were: maize-soybean rotation grown for grain only, continuous maize grown for grain and stover both with and without a winter rye cover crop, and a 31-species reconstructed pr...
The difference of reclaimed water qualities between in summer and in winter were proved considerable. Reclaimed water derived in spring or summer could be applied irrigating in some arid region, which have been considered a rational renewable resource of water. Yet in winter, reclaimed water would run off into river or stream in vain. The idea of storing it in winter and being ready for the nex...
