The present study aimed to investigate the effect of spraying with IAA and GA3 and the interaction between them on improvement the growth, yield and some biochemical and physiological characteristics of wheat plant (Triticum durum serf Triticum aestivum) of two cultivars, Mohamed Ben Bachir (MBB) and Hedab (HD), were growing under different concentrations of sea water salinity ( 10%, 30% and 60%) and the comparison plant control was also used.The results showed decreased continuously in plant length and yield (as spikes and 100 wheat grain weight), with increasing the concentrations of salinity during the growth period, compared with untreated plants. The concentrations of salinity used, has negatively effect on number of leaves and proliferate (first generation) and the leaf area of plant. On contrast, proline content was increased with increasing the concentrations of salinity, this revealed that the plant exhibited resistant to salinity. The spraying with regulators of growth used in the present study (IAA and GA3), showed significant effect on plant, in the extent of reducing the hurt effect of salinity on the vegetative measurements and some physiological components of plant.

“…Similarly, maturity was observed to last 5-11 days longer of for highland barley in the present study, suggesting that urea N fertilization promoted vegetative growth and delayed maturity. Fertilizer trials with barley planted at nine locations in Canada showed that straw and grain yield reached 2•5-3•8 and 2•5-3•4 t/ ha, respectively, v. ammonium nitrate fertilization rates of 45 and 135 kg N/ha (Bishop & MacEachern 1971). Abeledo et al (2003) noted that the total grain yield of four barley cultivars grown in Argentina reached 5•2-7 t/ha when urea fertilizer was applied at 350 kg N/ha.…”

SUMMARYA completely randomized experiment for planting highland barley in 36 field plots of the Lhasa Agricultural Experiment Station was applied to investigate the effect of urea nitrogen (N) fertilization levels of 0 (control), 156, 258, 363, 465 and 570 kg/ha on nutrient accumulation, in vitro rumen gas production and fermentation characteristics of highland barley straw (HBS). Each urea application was divided into three portions of 0.4, 0.3 and 0.3 and sequentially fertilized at seeding (growth stage (GS) 0), stem elongation (GS 32) and heading (GS 49), respectively. The maturity stage lasted 5-13 days longer in response to the urea N fertilization compared with the control. After removing grains, HBS biomass was harvested at maturity. The biomass yields of leaf, stem, straw and grain were increased quadratically with increasing urea N fertilization, and HBS and grain yields peaked at the estimated urea N fertilization levels of 385 and 428 kg/ha, respectively. The increase of urea N fertilization increased the accumulation of crude protein, cellulose and lignin, and decreased the content of ash and hemicellulose in HBS, resulting in a decrease of the energy content available to be metabolized. After incubating HBS for 72 h with rumen fluids from lactating cows, the urea N fertilization decreased in vitro dry matter disappearance and cumulative gas production, and slightly altered fermentation end-gas composition. Urea N fertilization decreased microbial volatile fatty acid production, but did not alter the ratio of lipogenic acetate and butyrate to glucogenic propionate. In a brief, the current urea N fertilization strategy promoted the growth of the highland barley and increased biomass yield, protein and cellulose accumulation of HBS. A urea N fertilization level ⩽385 kg/ha could be sufficient for growth of highland barley in Tibet without a consequent nutritive reduction in ruminal digestion.

Alaska has vast areas of undeveloped land with the potential for agricultural expansion. To develop renewable resources from oil royalty monies, the state has initiated a 24,000 ha agricultural demonstration project near Delta Junction, Alaska. Little is currently known, however, concerning the natural fertility of these virgin soils. A 43 factorial experiment was established, with barley (Hordeum vulgare L. var. ‘Otra’) as the test crop, to determine responses to fertilization the first 2 years after clearing on a Typic Cryopsamment soil. Fertilizer was applied before seeding each year at 0, 45, 90, and 135 kg N/ha; 0, 34, 68, and 102 kg P/ha; and 0, 34, 68, and 102 kg K/ha. Grain yields, protein contents, and subsequent soil‐test levels were measured. Nitrogen increased grain yields from 2 quintal/ha with no applied N in 1979 to 25 quintal/ha with 135 kg N/ha and from 4 quintal/ha with no applied N in 1980 to 31 quintal/ha with 135 kg N/ha. The yield response to N was linear throughout the 0 to 135 kg N/ha range in 1979, and both the linear and quadratic regression terms were significant in 1980. Cooler initial soil temperatures, lack of native residual nutrients, or N immobilization may have contributed to lower overall yields in 1979. Grain protein increased linearly with added N both years. Phosphorus increased yield up to 34 kg P/ha, with little response beyond that in either year. In 1979, both P and K were significant in increasing the yield response to N. In 1980, only K increased the yield response to N. Neither P nor K fertilization significantly increased grain protein contents. Multiple‐regression equations were developed to predict grain yields and protein contents with rates of fertilizer applied. When considering only N, P, and K fertilizer additions, equations with relatively high coefficients of determination were obtained for the first 2 years of production (Yield: R2 = 0.929,0.937 for 1979 and 1980; and protein: R2 = 0.684, 0.842 for 1979 and 1980, respectively). Thus, the application of fertilizer accounted for much of the variation in yield and protein contents.
