In order to assess the effects of different pesticides on nutrient levels of rice, three pesticides (Diazinon, Tricyclazole and Butachlor) which are commonly used in paddy fields in Iran were selected in a randomized complete block with 3 replicates in field condition. The result indicated that the impact of different pesticides on total protein and nitrogen, phosphorus and potassium ...
nine multiparous lactating cows averaging 171 days in milk were divided according to days in milk and milk production into three 3×3 latin squares with three 3-week periods to investigate the effect of rumen degradable protein on milk urea nitrogen. diets were formulated to provide 3 concentrations of dietary rumen degradable protein (9.8, 10.8, and 11.8% of dry matter), while rumen undegradabl...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
Many external and internal studies in based on the relevant literature and consult to tobacco experts,based on the experimental research of the years between 2004 and 2005, the basic model of soil-N of distribution was developed after analysising the content of nitrogen in the whole plant of tobacco. The model is designed to simulate dynamically absorption and distribution of nitrogen for tobac...
Background and purpose: Direct application of sewage sludge in agriculture is limited due to the presence of pathogens, improper fermentation of organic waste and heavy metals in the sludge. Co-composting of sewage sludge and other waste is a method for safe and healthy disposal to reuse sewage sludge. This study investigated the possibility of producing compost from sewage sludge and pistachio...
introduction: in iran, tuberose is ranked the forth after gladiolus, rose and carnation. these flowers are known as high quality products among which maximum exportation belongs to tuberose and gladiolus. in plant cultivation and development, adequate provision of nutrients is of crucial importance. tuberose needs plenty of nutrients to obtain the desirable quality and flowering. hence, tuberos...
BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
To investigate the influence of humic acid on the amount of absorption and allocation of elements to different parts of Satureja khuzestanica under salinity stress conditions, a greenhouse experiment was done as factorial based on a randomized complete block design in four replications. Factors included humic acid (zero, 10, 20, 30 and 40 mg kg-1 soil), and salinity stress (zero, 25, 50, 75 and...
The aim of this study was to evaluate the long-term (16-years) nitrogenefficiency after the application of organic and mineral fertilizers at two sitesLukavec (S1) and Suchdol (S2) with different soil and climatic conditions in theCzech Republic (Central Europe) and to determine grain yield and nitrogen contentwith regard to the requirements of protein content for baking quality of wheat.After ...
the monolithic oxynitride glasses in sio2-al2o3-b2o3 system were synthesized using sol-gel method. the porous, dried gels were heated in flowing ammonia for different times and varying temperatures. the nitrogen content of the oxynitride glasses was determined using an oxygen-nitrogen analyzer. the chemical bonding state and properties of glasses were investigated by means of fourier transform ...
