Summer Growth Response of Bermudagrass Fertilized with 12 Different Nitrogen Formulations

Clipping Management and Nitrogen Fertilization of Turfgrass: Growth, Nitrogen Utilization, and Quality

ers with a scientific basis for optimizing their N management strategies for turfgrass. The effect of returning grass clippings on turfgrass growth and Petrovic (1990) presented an excellent review of the quality has not been thoroughly examined. The objective of this refate of nitrogenous fertilizers applied to turfgrass. Part search was to determine the effects of returning grass clippings in...

Response of Fresh Forage, Dry Matter and Yield Components of Sorghum to Different level of Nitrogen and Cutting Height

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nitrogen is generally a limiting nutrient in crop production, and especially in sorghum, as it has been said to be the most responsive nutrient for its production. OBJECTIVES: Current study was conducted to assessment effect of urea fe...

Growth Response of Winter Wheat (Triticum aestivum L.) and Wild Barley (Hordeum spontaneum Koch) to Nitrogen

A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...

Maize response to water, salinity and nitrogen levels: physiological growth parameters and gas exchange

A split-split-plot design with three replications in two years of 2009 and 2010 was conducted to investigate the effect of different levels of irrigation water (main plot), salinity of irrigation water (sub-plot) and nitrogen fertilizer rate (sub-subplot) on maize growth rate and gas exchange. Irrigation treatments were I1 (1.0 crop evapotranspiration (ETc)+0.25ETc as leaching), I2 (0.75I1)...
