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...

Despite the importance of sesame (Sesamum indicum L.) in the world, this crop has received least research attention in Pakistan. Therefore, a field experiment was carried out to evaluate the performance of tillage system under various irrigation intervals and phosphorus levels on oil contents, yield and yield attributes of Sesame. The experiment was conducted at New Developmental Farm of the Un...

A field experiment with six treatments was conducted to study the nitrogen reserves in summer maize topsoil on the north China plain. Results showed that topdressing significantly increased topsoil nitrogen reserves. Summer corn topsoil nitrogen reserves were affected by several management measures. Shallow tillage, wheat straw no-returning and deep intertillage at the corn seedling stage signi...

to study the effects of different tillage systems on yield and some characteristic of wheat and also some soil properties in wheat dry land area, six experiments were performed in cold, moderate and semi-warm climatic conditions of kermanshah province in west of iran, in a randomized complete block design with five replications. experimental treatments were consisted of no-tillage, reduced till...

Strip tillage with various crop covers in peanut (Arachis hypogaea, L.) production has not shown a clear yield advantage over conventional tillage, but has been found to reduce yield losses from some diseases. This study was conducted to determine pod yield and disease incidence between two tillage practices, five winter cover crops, three peanut cultivars, and three fungicide programs. Convent...

A field experiment was performed from 2003 to 2008 to evaluate the effects of tillage system and nitrogen management regimes on crop yields and nitrate leaching from the fluvo-aquic soil with a winter wheat (Triticum aestivum L.)-maize (Zea mays L.) double-cropping system. The tillage systems consisted of conventional tillage (CT) and no-tillage (NT). Three nitrogen management regimes were incl...

The sugarbeet industry in the Pacific Northwest is interested in strip tillage (ST) primarily due to the potential savings in tillage costs. This study was conducted to evaluate the use of ST in the Pacific Northwest compared to conventional tillage (CT) practices and to evaluate N requirements of sugarbeet under ST and CT. The effect of tillage method (ST, moldboard plow [MP] system, and chise...

Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...
