to study the effects of different fertilizing systems using green manure and zeoponix on grain yield and its components in sunflower, an experiment was conducted at the research farm of collage of agriculture, tarbiat modares university in 2010 and 2011. the experimental treatments were arranged as split plot design on the base of a complete randomized block design with three replications. two ...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...

to study the effect of drought stress during using organic and chemical fertilizers on morphological, agronomic traits and the essential oil of coriander, a field experiment was conducted as split plot based on randomized complete block design in three replications at agricultural research station, college of agriculture, university of torbat heydarieh, iran during growing season of 2010-2011. ...

Land-use conversion from woodlands to tea fields in subtropical areas of central China leads to increased nitrous oxide (N2O) emissions, partly due to increased nitrogen fertilizer use. A field investigation of N2O using a static closed chamber-gas chromatography revealed that the average N2O fluxes in tea fields with 225 kg N ha(-1) yr(-1) fertilizer application were 9.4 ± 6.2 times higher tha...

In order to study the effect of chemical and biological fertilizers on silage corn under different plant densities, a split plot experiment was carried out in a randomized completely block design with three replicates in south western Iran. The main plot included nitrogen fertilizer treatment at three levels (N1: with out chemical and organic fertilizers, N2: 75% chemical fertilizer + 100% orga...

in order to develop the high intensive agriculture, more chemical fertilizers are applied to the soil that resulting in soil degradation and environment deterioration. application of organic manure is an important approach for maintaining and improving the soil fertility and increasing fertilizer use efficiency. therefore, in order to evaluate the effect of organic manures and chemical fertiliz...

In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...
