The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...

this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...

Improper tillage with no manure may cause a range of undesirable processes (destruction of soil structure, accelerate erosion, depletion of organic matter and fertility). A field experiment was conducted to observe the change in soil properties after incorporation of green manure crops and to find out the residual effect of green manure crops along with tillage on maize and rice yields during 2...

conservation tillage, a fast growing practice in iran, is considered as a means to achieve sustainability in agricultural systems. this study was carried out to determine the effect of tillage systems (no-tillage, minimum tillage and conventional tillage ) on yield and yield components of three irrigated wheat varieties. the field experiment was conducted at the experimental station of the univ...

ABSTRACT The population density of the reniform nematode, Rotylenchulus reniformis, was monitored at depths of 0 to 30, 30 to 60, 60 to 90, and 90 to 120 cm in a tillage and crop sequence trial in south Texas in 2000 and 2001. Main plots were subjected to three different tillage systems: conventional tillage (moldboard plowing and disking), ridge tillage, and no-tillage. Subplots were planted w...

NT will reduce soybean grain yields and economic returns, particularly during the first few years of adoption. Farmers have been encouraged to adopt no-tillage (NT) because Soybean grain yield response to NT systems depends of its positive environmental effects compared with other conservation tillage systems. Nevertheless, poor crop performance under NT manmainly upon soil drainage and previou...

In this study a comparison of the soil CO2 fluxes emitted from two maize (Zea mays L.) fields with the same soil type was performed. Each field was treated with a different tillage technique: conventional tillage (30 cm depth ploughing) and no-tillage. Measurements were performed in the Po Valley (Italy) from September to October 2012, covering both pre- and postharvesting conditions, by means ...
