Flours from African breadfruit, corn and defatted soybean were thoroughly mixed in a Hobart_-mixer at three variable, with the following combinations 40:5:55, 55:5:40, 70:5:25, 85:5:10 and 100:0:0% for African breadfruit, corn and soybean, respectively. These combinations were hydrated to moisture contents of 15, 18, 21, 24, and 27% and extruded at screw speed of 100, 120, 140, 160 and ISOrpm i...

The objective of this study was to evaluate the effects of sowing procedures and the seed sowing rate of kudzu (Pueraria phaseoloides cv. ‘Comum’) in corn on corn plant development, forage dry matter production, weed infestation and soybean plant development and yield. The kudzu seeds were either broadcasted over the terrain or sown in furrows (in the main plots) at rates, in both cases, of 400...

Nitrate loss from bioenergy crop fields has attracted considerable attention during the last few years because of its potential negative impact on aquatic and human health. Both controllable and uncontrollable factors for nitrate loss have been the subject of several previous studies. Due to differences in climate, biophysical dissimilarities and land management characteristics in different par...

Management systems influence soil quality over time. A study was carried out on Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA to evaluate the impact of crop rotations on soil quality from 2002 to 2007. The crop rotations comprised of continuous corn (CC), corn-soybean (CS) and corn–soybean-wheat-cowpea (CSW). Ten soil cores were collected at 0-7.5, 7.5-15, 15-22....

Effects of tillage and crop rotation o n nematode densities in tropical corn (Zea mays L. Pioneer Brand X304C) were determined in each of three seasons (1990-1992) in north Florida. Treatments in the factorial experiment consisted of conventional or n o tillage and rotation with sorghum (Sorghum bicolor [L.] Moench) or soybean (G/ycine max [L.] Merr.). Tillage and rotation treatments were maint...

In the US Corn Belt, a recent doubling in commodity prices has created incentives for landowners to convert grassland to corn and soybean cropping. Here, we use land cover data from the National Agricultural Statistics Service Cropland Data Layer to assess grassland conversion from 2006 to 2011 in the Western Corn Belt (WCB): five states including North Dakota, South Dakota, Nebraska, Minnesota...

Dual-use cover crops as forage for livestock could offer ecological and economic benefits when incorporated into rotations with corn (Zea mays L.) soybean (Glycine max (L.) Merr) in the Mid-South USA; however, information on implementation impact is limited. A factorial of sixteen cool-season species a no-cover control by two management systems (forage harvest residue left field) was repeated u...

The potential of conservation practices to maintain soil organic C (SOC) and reduce climate change impacts on yields is unknown. This study aimed validate the DayCent model with observed yield data CQESTR measured SOC in two agroecosystems, predict best sustain under projected change. Data were from a conventional tillage (CT) wheat (Triticum aestivum L.)–fallow rotation without N or 135 kg ha–...
