Biochar, a green way to deal with burning and burying biomass, has attracted more attention in recent years. To fill the gap of the effects of different biochar on crop yield in Northern China, the first field experiment was conducted in farmland located in Hebei Province. Biochars derived from two kinds of feedstocks (rice straw and corn stalk) were added into an Inceptisols area with differen...

Commercial sugarbeet yields range between 50 and 100 t clean beets/ha, with sugar concentrations of 17 to 18% on fresh weight (8 to 18 t sugar/ha; Milford, 2006). For 2010, beet yields in the U.S. averaged 62.2 t/ha. However, in the Imperial Valley (predominant cattle feeding region for the state of California), clean beet yields averaged 98.8 t/ha (USDA, 2010); 9 Imperial Valley beet growers t...

The low average grain yield (0.7 ton ha(-1)) of tef in Ethiopia is mainly attributed to low soil fertility, and inappropriate tillage and weeds control practices. Despite this, limited scientific information has been documented so far on their interaction effects on tef crop productivity in northern Ethiopia. The objective of this study was to assess the separate and interaction effects of till...

In order to study the influence of compost and biofertilizer on yield and essential oil of dill (Anethum graveolens L.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of Iran in 2012. The factors were compost in four levels (0,...

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 ...
