Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...

Fertilizer application control in reason is the key technology to improve operation quality, reduce fertilizer pollution, and cut down costs of production. A control system of variable rate fertilizer is developed based on microcontroller chip in the paper. The system can automatically control flow dosage by adjusting feed gate opening size and changing hydraulic motor speed of fertilizer conve...

Organoarsenical drugs are widely used in the production of broiler chickens in the United States. Feathers from these chickens are processed into a meal product that is used as an animal feed additive and as an organic fertilizer. Research conducted to date suggests that arsenical drugs, specifically roxarsone, used in poultry production result in the accumulation of arsenic in the keratinous m...

This note demonstrates that a certain class of stochastic problems for determination of optimal fertilizer application rates in the presence of fertilizer carry-over can be simplified to static, certainly equivalent problems. Conditions required for certainty equivalence to hold are: (1) fertilizer carry-over is agronomically equivalent to applied fertilizer; and (2) some addition of fertilizer...

Quantitative descriptions of the frequency and extent of contamination of apple cider with pathogenic bacteria were obtained using literature data and computer simulation. Probability distributions were chosen to describe the risk of apple contamination by each suspected pathway. Tree-picked apples may be contaminated by birds infected with Escherichia coli O157:H7 when orchards were located ne...

Plant Species and Variety Forage quality refers to digestible nutrient content (i.e., energy, protein), palatability and digestibility of the forage plant. Legumes (alfalfa, medics, cloves, vetch) are the highest quality group of forage grown in pastures. They are high in protein, energy (digestibility), and minerals. They also “fix” nitrogen fertilizer, making them very economical to grow. Inc...

In nursery stage, some silvicultural treatments have been applied to produce high quality of forest seedlings. Fertilizer application is one the most significant that effects on growth and development This study was performed in early November 2019 April 2020.The paper evaluates organic inorganic fertilizers Eucalyptus microtheca seedling under growing conditions. Organic fertilizer used with t...

Nitrous oxide (N2O) emission from grassland-based agriculture is an important source of atmospheric N2O. It is hence crucial to explore various solutions including farm nitrogen (N) management to mitigate N2O emissions without sacrificing farm profitability and food supply. This paper reviews major N management practices to lower N2O emission from grassland-based agriculture. Restricted grazing...

infected by ingesting unwashed vegetables contaminated by animal feces containing strongyloid larvae. Larvae mature into adults in the intestines. Sporadic cases of this infection in humans have been reported in many countries (7). In France, several autochthonous cases were suspected, but because of their rarity and diffi culty in identifi cation, they are not commonly reported (8). Eggs of Tr...
