Iron (Fe) deficiency-induced chlorosis is a major nutritional disorder in crops growing in calcareous soils. Iron deficiency in fruit tree crops causes chlorosis, decreases in vegetative growth and marked fruit yield and quality losses. Therefore, Fe fertilizers, either applied to the soil or delivered to the foliage, are used every year to control Fe deficiency in these crops. On the other han...

Cakchiquel farmers in Patzún, Guatemala stated that pest populations have increased in corn crops since they abandoned organic fertilization and adopted synthetic fertilizers. Given the dearth of scientific information about the effects of fertilization practices on pests, a controlled experiment was performed to elucidate these interactions. Pests, their natural enemies, and nutritional status...

application of bio-fertilizers, especially mycorrhiza as substituent or complement of chemical fertilizers is one of the most important strategies for plant nutrition in sustainable management of agro-ecosystems. in order to evaluate the separated and integrated application of mycorrhiza biological fertilizer and phosphorus chemical fertilizers on growth indices of chickpea (cicer arietinum l.)...

Biological and nano fertilizers are alternative supplements to chemical security for the sustainability of agricultural production. This study is present investigate effect biological on quantitative qualitative yield cow pea during two crop years (2018-2019 2019-2020) in research farm South Agricultural Research Education Center Kerman province, Iran. experiment was carried out factorial desig...

conclusion adrenal iron in β-tm can be reliably measured in 3 tesla mri. the results highlight the absence of correlation between adrenal iron deposition both with serum ferritin and hepatic iron. results among patients, there was no significant correlation between plasma ferritin and adrenal t2*. significant difference was detected among t2* values of adrenals between the patient and control g...

AIMS The recent increases in food prices caused by the corresponding increases in fertilizer costs have highlighted the demand for reducing the overuse of fertilizers in industrial agriculture. There has been increasing interest in developing plant root-targeted delivery (RTD) of fertilizers in order to address the problem of inefficient fertilizer use. The aim of this study is to develop a low...

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

in order to study the effect of organic fertilizers application on increasing nitrogen efficiency and also quantitative and qualitative characteristics of sugar beet, a series of experiments were performed for two years (2008 and 2009) using three amino acid containing organic fertilizers at motahari research station of sugar beet seed institute (sbsi), karaj, iran. four rates of organic fertil...
