Differential effects of glyphosate on germination and chlorophyll in Zea Mays plants

Abstract We studied the glyphosate effect on the germination and chlorophyll content of two corn varieties. The first variety is local “beldi” not improved and the second is a variety selected and imported. Our analysis showed that the imported variety is more tolerant than local. The latter would have been affected by the direct effects of glyphosate by oxidative stress manifesting itself by a strong inhibition of germination and an increased degradation of chlorophyll. However, the imported variety behaved as capable of degrading glyphosate to aminomethylphosphonic acid resulting in improved herbicide resistance.

The study was conducted on 100 numbers of respondents in three villages named Chengerkuthi Khalisamari, Jatamari, and Choto Khalisamari under Khalisamari Gram Panchayat of Coochbehar district of West Bengal. The statistical method used for analysis and interpretation of raw data were mean, frequency percentage and paired ‘t’ test. It is noticeable due to high remunerative and regularity of income, the youth and middle aged group are more attracted for migration. The study also reveals migration process transformed the occupational distribution of the respondents massively. The income variation factor before and after migration are also in favour of migration. It is evident that after migration the family daily life standard changed towards a positive direction. The number of cell phone users and bank account holder also increased.

Evaluation of the contribution of forest rangelands in the forage balance in the western part of the Central Middle Atlas: Case of the forests of Azrou, Jbel Aoua South and Sidi M’guild

Abstract Range management in Morocco is based on traditional practices where the land is used by a community for grazing by sheep. In the Atlas Mountains rangelands and forest lands are extensively used by grazing animals and even if the vegetation is abundant the cover is ongoing degradation especially in summer. The forest as a rich ecosystem where the plant community is constituted by Quercus and Cedrus sp. where overgrazing has an negative impact on the vegetation inducing degradation. The bred of sheep is Timahdit a bred which is adapted to the high mountain cold of the winter. The range is overgrazed by sheep and undergoes profound mutation with major degradation due to higher pressure by the increasing number of animals of the community which have the right to use the herbaceous cover. This study have the objective to determine the contribution of the range to meet the needs of the animals in the occidental region of the atlas mountains and determine the difference between the potential of the range and the need of the grazing sheep. The results showed that the herbaceous cover is over used by high numbers of animals. So a more rational use of the range is necessary to stop the degradation and sustain the production potential of the forest. The participatory method which includes the population in the decision making will allow better use of the range and sustain the resources and the forest by stopping degradation and a rational use of the range.
