Effective microorganisms (EM), a culture of coexisting beneficial microorganisms predominantly consisting of species of photosynthetic and lactic acid bacteria, yeast and actinomycetes, has been developed by Japanese Scientists. In the present study effect of soil sterilization on performance of a commercial EM biofertilizer (EM Bioab), in improving crop growth and yield in wheat (Triticum aest...

Wheat grain protein content (GPC) is a key component when evaluating wheat nutrition. It is also important to determine wheat GPC before harvest for agricultural and food process enterprises in order to optimize the wheat grading process. Wheat GPC across a field is spatially variable due to the inherent variability of soil properties and position in the landscape. The objectives of this field ...

Demand for food security and the current global warming situation make high and strict demands on the North China Plain for both food production and the inhibition of agricultural carbon emissions. To explore the most effective way to decrease soil CO2 emissions and maintain high grain yield, studies were conducted during the 2012 and 2013 summer maize growing seasons to assess the effects of w...

Ten elite wheat inbred lines / cultivars were tested for grain yield stability at five different locations under the rainfed conditions in the North West Frontier Province of Pakistan. These inbred lines were exposed to different soil types, soil fertility, moisture levels and temperatures. GxE interaction mean squares were highly significant for grain yield. The overall mean grain yield perfor...

We determined the Cd, Cr, Cu, Ni, Pb, and Zn concentrations in soil samples collected along the eight main outlet roads of Poznań. Samples were collected at distances of 1, 5, and 10 m from the roadway edges at depth intervals of 0-20 and 40-60 cm. The metal content was determined in seven grain size fractions. The highest metal concentrations were observed in the smallest fraction (<0.063 mm),...

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...

gypsum found in the soil beneath the foundation of structures, specially hydraulic structures, can cause serious damage to them. the mechanical behavior of gypsiferous soils has not so far been investigated in detail except for the works of petrukhin (1993). here, it has been tried to investigate the mechanical behavior and the effect of soil being leached on settlement and strength of these ki...

Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...
