in order to evaluate the effect of water deficit and different fertilizer levels on yield and some agro-morphological characteristics of moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of shahrekord university during 2013-2014 growing season. main factor was three levels of irrigation regimes including: 100...

plant secondary materials play an important role in health and human nutrition. according to the importance of coneflower in the production of secondary materials and also the effect of nutrient on the amount of secondary materials, a pot experiment was conducted with a completely randomized design six treatments and three replications in sari university of agricultural sciences and natural res...

introduction: today, production of organic farming and gardening is rising. the use of organic fertilizers such as animal manure has a long history. in recent years, the use of fertilizers and manure for providing the nutritional needs of plants, improve soil physical and chemical structure and reduce the environmental issues have been observed. animal manures can increase soil organic matter a...

one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

Ammonia emission from animal production is a major environmental problem and has impacts on the animal health and working environment inside production houses. Ammonia is formed in manure by the enzymatic degradation of urinary urea and catalyzed by urease that is present in feces. We have determined and compared the urease activity in feces and manure (a urine and feces mixture) from pigs and ...

cattle manure is made from liquid and solid waste. it contains the straw and stubble that is used for the cattle bed. density of the cattle manure is inherently low, which is difficult and costly to transport. pelleting is one method to solve this problem. the physical properties of the pelleted cattle manure was investigated in this study. the results showed that by increasing moisture content...

The objectives of this study were to estimate the prevalence of Mycobacterium avium subsp. paratuberculosis (MAP) among deer and rabbits surrounding infected and noninfected Minnesota dairy farms using fecal culture, and to describe the frequency that farm management practices were used that could potentially lead to transmission of infection between these species. Fecal samples from cows and t...

this experiment was conducted to improve the nutritive value of barley stubble for two consecutive years. after harvesting crop, at first year, a completely randomized design, with a 3 × 3 factorial experiment was conducted in which 27 plots were divided into nine treatments. the treatments including zero, 2.5 and five percent urea each with zero, three and six percent molasses were mixed with ...

in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...
