Field experiments were conducted to determine the effects of organic andinorganic amendments on weed suppression in sweet maize cultivation (Zea maysL.). A randomized complete block design was employed with four replicates pertreatment with each organic amendment used at half (x/2), single (x=10 t ha-1) anddouble (2x) rates (organic fertilization: cow manure, poultry manure and barleymulch; syn...

This study was conducted to investigate direct short-term impact of vermicompost on some soil biological properties by monitoring changes after addition of vermicompost as compared to farmyard manure in an alkaline soil with high lime content from semiarid Mediterranean region of Turkey. For this purpose, mixtures of soil and organic fertilizers in different doses were incubated under greenhous...

Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...

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 study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the research institute of forest and rangelands, karaj, iran, in 2013-14. the treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). the experimental design was a factorial experiment based on randomized ...
