The effects of organic and mineral nitrogen fertilization on nitrogen leaching and nitrate concentration in percolated water were simulated using the CANDY model. In a long-term IOSDV field experiment carried out from 1983 to the present in Lukavec, Czech Republic, increasing nitrogen rates from 0 kg to 200 kg N*ha in mineral fertilizers were combined with the application of farmyard manure or ...

A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...

Optimum seeding rate and row spacing are important for uniform crop establishment harvest of quality seed. Field experiment was conducted at three locations in 2014 2015 to study the influence seed on multiplication factor yield durum wheat. Triplicate split plot design used. The highest found a 125 kg ha−1 with 10 cm but not significant rates 100 spacing, 75 20 2014, 150 Debre Zeit. At Chefe D...

BACKGROUND, AIMS AND SCOPE The global problem concerning contamination of the environment as a consequence of human activities is increasing. Most of the environmental contaminants are chemical by-products and heavy metals such as lead (Pb). Lead released into the environment makes its way into the air, soil and water. Lead contributes to a variety of health effects such as decline in mental, c...

Grazing stimulates root and forage mass of perennial pastures, but few studies have addressed the effects grazing on annual pastures which are often grown in short periods within integrated crop–livestock systems (ICLS). In these N fertilization is a common practice to increase mass, its morphology unclear. field experiment, we evaluated how intensities (ungrazed, moderate, heavy grazing) rates...

To investigate the effects of fertilization, tillage, and their interaction on maize yield, an experiment rice-maize was conducted 2018/19 2019/20 at Agriculture Forestry University (AFU), Rampur, Chitwan, Nepal. The in a split-plot with two establishment methods viz. (i) zero tillage followed after (fa) conventionally tilled dry direct seeded rice (ZT fa CT-DDSR) (ii) conventional puddled tran...

The steady-state levels of reactive oxygen species (ROS) determined by the balance between their rates of production and rates of clearance by scavenging mechanisms could be called ecological oxidative balance (EOB) in the biological system. A first-line drug with superior efficacy, used in treating Mycobacterium tuberculosis infection, is rimifon (isonicotinic acid hydrazide, INH). One of the ...

Dilutional coagulopathy can be reversed with fibrinogen concentrate. Effects of different fibrinogen dosages on clot function are not defined; high doses may increase the risk of thromboemboembolism. This study investigated the effect of six fibrinogen dosages on coagulation profile and blood loss in coagulopathic pigs. Forty-two pigs underwent a 60% hemodilution (HD) with hydroxyethylstarch (H...

breeding and cropping cultivars with high weed competitiveness have played an important role in the non-chemical weed management. this experiment was carried out in order to study the effect of nitrogen on weed tolerance and competition indices of five wheat cultivars at the research field of agricultural faculty, university of mohaghegh ardabili, during 2010-2011 growing season. experimental f...

Broomrapes (Phelipanche spp. and Orobanche spp.) are holoparasitic plants that cause tremendous losses of agricultural crops worldwide. Broomrape control is extremely difficult and only amino acid biosynthesis-inhibiting herbicides present an acceptable control level. It is expected that broomrape resistance to these herbicides is not long in coming. Our objective was to develop a broomrape con...
