Open-pit mines generally have operational problems such as puddling and inappropriate water flow over haul roads, particularly if located in areas with high rainfall indices. These situations increase truck cycle times, promote rapid deterioration of haul-road wearing-course material, reduce productivity due to downtime road maintenance. In addition, costs are raised the frequency maintenance t...

Puddling of clay soils for rice transplanting causes a loss soil structure and vertical shrinkage cracks that are hypothesized to hamper sunflower root growth in the following dry season. To alleviate constraints yield, we examined effects three levels mulch two irrigation regimes season on clay-textured coastal zone Bangladesh. These treatments were no-mulch, straw at 5 t ha−1 10 ha−1, applied...

Rice is the major staple food of Jharkhand. Jharkhand produces 2.88 million tonnes, in area about 1.59 hectare with average production 1.81 tonne per hectare. Paddy cultivation involves different operations like sowing paddy for seedlings growing, puddling, seedling uprooting & transplanting, weeding, spraying insecticides/pesticides, harvesting and threshing. Among these threshing an important...

Wetland rice agriculture includes puddling practices, which facilitate transplanting and weed control easier lowers water nutrient loss through percolation. However, in addition to these benefits, the alters soil's physical properties, is harmful subsequent crops.100 gridded soil sample was collected from 24 panchayats of Tangi Choudwar. In this study, properties like texture, holding capacity ...
