Pitaya Cactus Endophytic Bacteria a Sustainable Option to Reduce and Optimize NH4NO3 in Phaseolus vulgaris
Abstract: The Phaseolus vulgaris crop demands nitrogen fertilizer as NH4NO3 for healthy growth. However, the application of NH4NO3 not uptaken by plant roots, generates N2O, a gas that contributes to the greenhouse effect besides loss of soil fertility; a sustainable option is to reduce up to 50% and to optimize it by inoculating P. vulgaris seeds with genera and species of plant growth promoting endophytic bacteria isolated from a desert xerophyte …

Use of Pesticides leads to Environmental degradation
Abstract: Pesticides are extensively used for agriculture but residues can reach aquaticecosystems, frequently. They are transferred from pytoplankton to fish and human, ultimately. Pyrethroid insecticides are utilized in place of organochlorine,organophosphorus and carbonate to control different forms of pests and raise yield. Pyrethroid intoxication causes cellular damage and increases freeradicals, which leads to lipid peroxidation and, ultimately, oxidative stress.To reduce damage to environment and biologicalsystems by pesticides should be played attention …
