Limited data are available on the fate of clothianidin under realistic agricultural production conditions. The present study is the first large-scale assessment of clothianidin residues in soil and bee-relevant matrices from corn and canola fields after multiple years of seed-treatment use. The average soil concentration from 50 Midwest US corn fields with 2 yr to 11 yr of planting clothianidin...

Cereal crops are used throughout the world for livestock feed. When they are managed properly they provide excellent grazing and high-quality silage or hay. It is important to remember that grazing should occur during the vegetative stage and silage or hay harvest should occur during flowering to early seed fill. Corn is one of the few annual crops that will provide quality forage after seed ma...

Ipomoea turpethum R. Br. [= Operculina terpethum (Linn.) Silva Manso (Hindi—Nisoth, Pitohri), a perennial plant with a muchtwisted stem is found through out India. It is reported to be highly medicinal and is cultivated occasionally in gardens as an ornamental plant. Some hydroxy fatty acids, butulin, lupeol and sitosterol have been found in the plant. Seed gums are important vegetable products...

To evaluate the effect of residue of sulfonylurea herbicides and  wheat residues on the growth and yield of sunflower, a split factorial experiment was conducted based on a randomized complete block design (RCBD) with four replications at the College of Agriculture, Shiraz University, Shiraz, Iran. The treatments included with and without wheat residues from the tested farm as the main plots, a...

Crop canopies and residues have been shown to intercept a significant amount of rainfall. However, rainfall or irrigation interception by crops and residues has often been overlooked in hydrologic modelling. Crop canopy interception is controlled by canopy density and rainfall intensity and duration. Crop residue interception is a function of crop residue type, residue density and cover, and ra...

abstract this study was conducted under cold climate condition in khorasan during 2006-2008 growing seasons to evaluation of soil fertility in wheat-based double cropping systems under different rate of nitrogen and return of crop residues. a randomized complete block design with split-split plot arrangement and three replicates was used. main plots were five crop rotations namely: wheat-wheat,...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...
