ing beef cattle feedlot manure under tilled and n-till conditions. This study was conducted on a steep (12% average slope) Monona silt loam (fine-silty, mixed, superactive, mesic Typic Hapludolls) soil near Treynor, Iowa. The experiment was a split-plot with no-till and disked systems as main plots and subplots of manure, fertilizer, and check with or without a grass hedge. A rainfall simulator...

a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

In order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of Agriculture, Shiraz University, Shiraz, Iran. The study was carried out in a factorial experiment laid out based on a completely randomized block desig...

The purpose of this study is to investigate the interactions between irrigation and fertilizer treatments on soil NO3 (-)-N content and vertical distribution under drip fertigation in greenhouse tomatoes. Randomized block design with three replications and the treatments consisting of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (100%  E...

Mulching is widely used to increase crop yield in semiarid regions in northwestern China, but little is known about the effect of different mulching systems on the microbial properties of the soil, which play an important role in agroecosystemic functioning and nutrient cycling. Based on a 4-year spring maize (Zea mays L.) field experiment at Changwu Agricultural and Ecological Experimental Sta...

Experiments described were conducted to define the vitamin A status of ewes and lambs grazing orchardgrass fertilized at various levels of N or N plus micro-elements. Four fertilizer treatments (56 kg N/ha; 168 kg N/ha; 504 kg N/ha; 504 kg N/ha + Co, Cu, Mo, Zn and S) were applied to replicated hay and pasture plots of Potomac orchardgrass on a Gilpin silt loam soil. Ewe lambs were allocated ra...

The study was conducted to determine the interactive effects of biochar application in combination with farm yard manure (FYM) and nitrogen (N) fertilizer on soil organic matter (SOM) and mineral nitrogen at Agricultural Research Farm of Khyber Pakhtunkhwa Agricultural University Peshawar in 2010-2011. Soil samples at 0-15 cm depth were collected from maize and mungbean plots at harvest stage (...
