The study analyzed the effects of pesticides on selected vegetable crops grown in Abakaliki, Ebonyi State Nigeria. pesticide Dichlorvos (DD Force) was used to treat sites planted with Amaranth, cucumber, and okra. Soil samples were randomly collected after 30 days incorporation tested for traces chloride phosphate. results analysis showed that amaranth, okra residue concentration exceeded maxim...

Fenpyroximate is an effective acaricide on several food crops. In the present study, dissipation of residue of this acaricide in black tea, tea infusion and spent tea was studied. Analysis was carried out using high performance liquid chromatography with diode array detection. The rate of dissipation was found to vary with the nature of the substrate. In tea leaves the half-life of fenpyroximat...

The problems of atmospheric pollutants are causing significant concern across the globe and in India. aggravated level surrounding environment poses serious threats to normal living conditions by deteriorating air quality adverse health impacts. Pollutant concentration increases during harvesting seasons Kharif/Rabi due stubble burning is other points or mobile sources. present study intended m...

Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...

Biomass burning covers open fires (forest and grassland fires, crop residue burning in fields, etc.) and biofuel combustion (crop residues and wood, etc., used as fuel). As a large agricultural country, China may produce large quantities of mercury emissions from biomass burning. A new mercury emission inventory in China is needed because previous studies reflected outdated biomass burning with...

Fly ash is a by-product from burning of coal. Utilization fly by carbothermic reduction an effective way to recover aluminum, silicon, and iron enhance product-added value. This work focused on the phase transformation Al2O3, SiO2 Fe2O3 during in air. A comparative analysis air nitrogen was made. Thermodynamics performed illustrate possible reactions for residue condensate. X-ray diffraction (X...

The allelopathic influence of plant residues of three dominant weeds of NorthWestern Himalayan region, namely, Eupatorium adenophorum, Ageratum conyzoides and Lantana camara was observed on the germination and early growth of three common cereal crops viz., Triticum aestivum cv. HPW-42, Oryza sativa cv. Hasanshrai Basmati and Zea mays cv. Girija. The effect of soil amended with weed residues at...
