continuous and excessive use of organophosphorus compounds has led to thecontamination of water and soil ecosystems. the degradation of organophosphorusinsecticides, chlorpyrifos, chlorpyrifos- methyl, cyanophos and malathion in mineral saltsmedia were studied. the effect of additional biofertilizers, singly or combined withorganic amendments, on chlorpyrifos and cyanophos degrading activity in...

Red chili (Capsicum annum L.) is one of the important horticultural crops, yet its productivity still relatively low. This study aims to determine red improvement through use inorganic fertilizer and biofertilizer. The factorial randomized group design (RAK) experimental with 2 factors 3 replicates (10 plants for each replicate) was used in this research. Factor I consisted four doses (K), name...

Due to the excessive use of inorganic fertilizers, structure soil is deteriorated, and product quality adversely affected. For this reason, environmentally friendly organic fertilizers in production has increased recent years. A field experiment was conducted a plastic greenhouse Research Center Field at General Directorate Agriculture, Dohuk Governorate, Northern region Iraq during autumn seas...

in this study, the effect of irrigation regimes and plant nutrition were evaluated as split plot arrangment based on randomized complete block design with three replications in 2010. treatments consisted of irrigation regimes at three levels: well-irrigation, irrigation disruption at vegetative growth stage, and irrigation disruption at reproductive growth stage as main plots and combination of...

To boost crop yield on arable land, fertilizers have been extensively utilized. A country may become food-self-sufficient by using more chemical in agriculture, yet chemicals are harmful to the environment and living things. Biofertilizers organic substances that make use of microorganisms increase fertility soil, which helps safeguard soil's health also quality products. provide nutrients thro...

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and pollution avoided. The study aimed determine the effect of biofertilizers with different compositions microorganisms on growth maize plants. research was carried out in a greenhouse. Maize plants were fertilized by two kinds microorganisms. first biofertilizer contained Azotobacter sp, Azospirillum R...

in order to investigate the effect of different levels of biological fertilizers on potato performance (cv. marfona), an experiment was carried out as strip plot based on rcb design with 3 replications in 2011 at isfahan. treatments included nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and nitroxin+ phosphate at 4 levels (0+0: control, 20+100, 30+150 and 50+200...

sweet basil (ocimum basilicum l.) is one of the most popular medicinal plants that containing essential oil. essential oil of this plant has been utilized extensively in the food, pharmaceutical and cosmetics industries. in this study, a pot experiment was conducted to evaluate the effect of biological fertilizers of biosulfur, nitroxin and super absorbent polymer and their interactions on the ...
