In order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (Foeniculum vulgare Miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. Arbuscular mycorrhizal fungi (strain Sebacina vermifera) and phosphate dissolving bacteria (genera Peseudomonas) were applied as ...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

A laboratory investigation was conducted to evaluate the efficiency of four phosphate fertilizers, including diammonium phosphate (DAP), potassium phosphate monobasic (MPP), calcium superphosphateon (SSP), and calcium phosphate tribasic (TCP), in terms of the toxicity and bioavailability of Cd in contaminated soils. The efficiency of immobilization was evaluated on the basis of two criteria: (a...

BACKGROUND Radionuclides in the phosphate fertilizers belonging to (232)Th and (238)U and (40) K are the major contributors to the outdoor terrestrial natural radiation. These radionuclides are transferred from fertilizer to food through soil. MATERIALS AND METHODS Present work deals with the alpha activity in the different parts of the potato (Solanum Tuberosum) plants grown under controlled...

Chronic Kidney Disease of unknown etiology (CKDu) has escalated into an epidemic in North Central Province (NCP) and adjacent farming areas in the dry zone of Sri Lanka. Studies have shown that this special type of CKD is a toxic nephropathy and arsenic may play a causative role along with a number of other heavy metals. We investigated the hypothesis that chemical fertilizers and pesticide cou...

A field experiment was carried out in the Research and Production Station, National Research Center, El-Nobaria during the season, 2009 to evaluate the effect of cobalt and different sources of phosphorus fertilizers on the growth, yield quantity and quality of tomato. Treatments can be arranged in descending order as follows: Mono super phosphate (MSP) > Triple super phosphate (TSP) > Rock pho...

Tracking information about fertilizers consumption in the world is very important since they are used to produce agriculture commodities. Brazil consumes a large amount of fertilizers due to its large-scale agriculture fields. Most of these fertilizers are currently imported. The analysis of consumption of major fertilizers, such as Nitrogen-Phosphorus-Potassium (NPK), Sulfur, Phosphate Rock, P...

management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...
