Weed behaviour in crop fields has been extensively studied; nevertheless, limited knowledge is available for particular cropping systems, such as no-till systems. Improving weed management under conditions requires an understanding of the interaction between residues and seedling emergence process. This study aimed to evaluate influence maize wheat residues, applied three different quantities (...

Small scale framers mainly face to farm sprawl, land multiplicity and diminution, losing resources and cultural mechanization incapability. Whereas the multiple cropping has more sustainability in unsuitable geographical regions environmentally, it is one of the suitable ways for small scale farmers' livelihood. Nonetheless, there is indispensable to assertion of multiple cropping profitabili...

corn–soybean cropping systems predominate. The effect of these cropping systems on indicators of soil quality Understanding long-term management effects on soil properties is only partially understood. Soil organic C has been is necessary to determine the relative sustainability of cropping systems. Soil physical, chemical, and biological properties were measured shown to increase in monocultur...

Rainfall variability has a significant impact on crop production with manifestations in frequent crop failure in semiarid areas. This study used the parameterized APSIM crop model to investigate how rainfall variability may affect yields of improved sorghum varieties based on long-term historical rainfall and projected climate. Analyses of historical rainfall indicate a mix of nonsignificant an...
