limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

in order to study the effects of plant density and nitrogen rates on yield, nitrate and protein of silage maize (ksc 704) in shahrekord area, an experiment was conducted during 2007 growing season at the agricultural research farm of shahrekord university. the experimental design of the experiment was randomized complete blocks with factorial arrangement with four replications. treatment consis...

in order to investigate the effects of different irrigation regimes and zeolit on the yield, yield componentsand relative leaf water content of sorghum, a field experiment was conducted in split plot in time andspace based on randomized complete block design with three replicates in research station of shahidbahonar university of kerman in 2011. irrigation regimes (100, 80, 60 and 40% of field ...

Switchgrass (Panicum virgatum L.) is being evaluated as a bioenergy crop for the northern Great Plains. Field measurements of CO2, CH4, and N2O flux are needed to estimate the net greenhouse gas (GHG) balance of this biofeedstock. The study objective was to determine effects of recommended Nitrogen (N) fertilization (67 kg ha 1 of N applied) and unfertilized switchgrass on growing season soil-a...

Limited information is available on water and nitrogen (N) management of sugarcane (Saccharum officinarum L.) in Khuzestan, southwestern Iran, where this crop is currently and extensively grown under heavy irrigation and N fertilization. Therefore, a field experiment was conducted from September 2000 to March 2002 at the Research Department of Karoon Agro-industry in Khuzestan to determine the ...

Methane-oxidizing bacteria (methanotrophs) in the soil are a unique group of methylotrophic bacteria that utilize methane (CH4) as their sole source of carbon and energy which limit the flux of methane to the atmosphere from soils and consume atmospheric methane. A field experiment was conducted to determine the effect of nitrogen application rates and the nitrification inhibitor dicyandiamide ...

The present study was undertaken to develop potassium management recommendations that maximize yield and post harvest quality of tomato. Studies were conducted at Faculty of Agriculture, Gomal University, Dera Ismail Khan, KPK, Pakistan during 2008-2009. A pot experiment was designed, which included six potassium fertilizer treatments (75, 150, 225, 300, 375, 450 Kg K2O ha ) with basal doses of...
