Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize w...

Abstract The objective of this work was to evaluate the effects application glyphosate herbicide on seed reserve mobilization and seedling morphology genetically modified soybean. Two herbicide-tolerant (TMG 1264RR P98Y11) two herbicide-sensitive (Emgopa 315 UFUS 7415) cultivars were selected for study subjected germination, length, tests after treatments with solutions at concentrations 0.00, ...

Information on weed distribution within the field is necessary to implement spatially variable herbicide application. Since hand labor is costly, an automated weed control system could be feasible. This paper deals with the development of an algorithm for real time specific weed recognition system based on Histogram Analysis of an image that is used for the weed classification. This algorithm i...

AproductADF1 : : : FN of invertible block-diagonalmatrices will be bandedwith a banded inverse. We establish this factorization with the numberN controlled by the bandwidthsw and not by the matrix size n:When A is an orthogonal matrix, or a permutation, or banded plus finite rank, the factors Fi have w D 1 and generate that corresponding group. In the case of infinite matrices, conjectures rema...

To explore the synergistic effects of modified biochar in purification herbicide-containing wastewater, effect addition on removal herbicide atrazine wastewater was verified by bags a small reed bed-constructed wetland laboratory. The results showed that sulfuric acid-modified could increase rate from 50% to 70%, and COD elimination 66.7% 86.7%. constructed bed improved efficiency total nitroge...

Treatment of field pennycress (Thlaspi arvense L.) leaves with the herbicide chlorsulfuron resulted in a decrease in the export of assimilate. Twelve hours after a spot application of 1 microgram, assimilate translocation was 70% of that in control leaves. In excised leaves treated with chlorsulfuron the total amounts of sugars and free amino acids were 150 and 170%, respectively, of the amount...
