This study presents a global scale analysis of cropping intensity, crop duration and fallow land extent computed by using the global dataset on monthly irrigated and rainfed crop areas MIRCA2000. MIRCA2000 was mainly derived from census data and crop calendars from literature. Global cropland extent was 16 million km around the year 2000 of which 4.4 million km (28%) was fallow, resulting in an...

Abstract We previously reported soybean fields double-cropped with winter wheat having reduced cyst nematode (SCN) ( Heterodera glycines ) counts compared to fallow. A follow-up metagenomics study identified several fungal and bacterial taxa enriched in fields, some were parasitize SCN. Knowing that phytocompounds potential nematicidal activity are released via roots stubble, we implemented a d...

residue management has a direct impact on soil physical and chemical characteristics which in turn have identical effects on sustainability of crop production in agroecosystems. the effects of wheat residual management practices (burning, plowing under and removal) on soil physical and chemical characteristics were investigated in this research. treatments were compared in a complete block desi...

Two temperate corn (Zea mays) hybrids (Pioneer 3320 and Northrup King 508), two tropical corn cultivars (Pioneer X304C hybrid and Florida SYN-1 experimental open pollinated cultivar), the sorghum (Sorghum bicolor) x sudangrass (Sorghum sudanense) hybrid DeKalb SX-17, and the sorghum hybrid DeKalb FS25E were compared for effect on nematode densities and forage yield in three plantings (one singl...
