to study the effect of three soil fertilizing systems (chemical, organic, and integrated) on forage yield and quality of globe artichoke (cynara scolymus) an experiment was conducted using a randomized complete block design (rcbd) of four replications at the research farm of college of agriculture, university of tehran, karaj, iran in 2006. the treatments included 5 levels of chemical fertilize...

introduction due to the development of sustainable agriculture and the reduction of utilizing chemical fertilizers, it is essential to use organic fertilizer. organic matter is vital to soil fertility and its productivity. to maintain the level of fertility and the strength of soil, organic matter levels should be maintained at an appropriate level. unfortunately, the level of organic matter in...

Improving soil fertility/productivity and reducing environmental impact of nitrogen (N) fertilization are essential for sustainable agriculture. Quantifying the contribution of various fertilization regimes to soil N storage and loss has been lacking in a wide range of spatiotemporal scales. Based on data collected from field experiments at three typical agricultural zones in China, soil N dyna...

a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...

Abstract To deal with the heat dissipation problem produced by a high integrated circuit, preparation of spreaders excellent transportation performance is increasing in demand. The Ti 3 C 2 MXene sheets and copper particles were fully contacted cellulose nanofibers high-speed mixer, composite film was prepared as spreader under action vacuum-assisted filtration. are connected esterification car...

Diamond offers great potential for use as a thermal spreader in various applications, including power electronics and radio-frequency (RF) applications. However, to be used an efficient spreader, the atomically smooth surface of diamond is critical bonded with chips. Herein, polishing technique 2-inch diameter wafer-scale bulk polycrystalline substrate proposed. In this work, 350 μm thick grown...

in order to investigate the response of coneflower to applying chemical fertilizer and incorporation with municipal solid waste compost (mswc), a pot experiment was conducted as completely randomized design with six treatments included: control (without applying chemical fertilizer and compost), chemical fertilizer (150 kg n, 120 kg p2o5 and 250 kg k2o per hectare from urea, triple super phosph...
