Lori M. Bruce Hrishikesh D. Tamhankar Department of Electrical and Computer Engineering, Mississippi State University, Mississippi State, MS 39762 Experiments were conducted to examine the use of spectral reflectance curves for discriminating between plant species across moisture levels. Weed species and soybean were grown at three moisture levels, and spectral reflectance data and leaf water p...

in order to examine the multi-species weed competition in corn field an experiment as an interval mapping was carried out at the agricultural research field of ferdowsi university of mashhad during growing season 2009-2010. at 3-4 leafy stages of corn, 20 non-destructive quadrates determine and the density of weeds was counted separately. at the same time, 20 destructive quadrates determine and...

to evaluate the sensitivity of different crops included some pulses to simulated metribuzin soil residues, an experiment was conducted in completely randomized design with factorial arrangement and four replications in research greenhouse of college of agriculture, ferdowsi university of mashhad. treatments included of 8 crops (chickpea, common bean, lentil, corn, wheat, barley, rape seed and s...

Record low growing degree days and suboptimal growing conditions for corn in 2009 significantly delayed corn dry down and harvest in much of Wisconsin. As a result, near optimal environmental conditions (frost before full maturity) were present in the fall of 2009 for field mold growth. Field molds indentified on corn in the fall of 2009 by the University of Wisconsin Department of Plant Pathol...

the european corn borer, ostrinia nubilalis (hübner), is an important insect pest of corn, zea mays l., crop in moghan region. in field experiments, the density of eggs and larvae of o.nubilalis and percentage of eggs and larvae parasitisms were studied on four corn hybrids ns704 (commercial cultivar), ns770, ns640 and mv524 (cultivars with high yield). furthermore, in this study, the predators...
