Abstract

A field experiment was conducted in Al-Muthanna Governorate to studied influence of different levels of phosphorus three rate (0,50,100) kg P h^-1 and three Payments of application (once , twice ,and three parts) on phosphorus released in the soil solution . The order first equation was used to explanation of the results. The result was showed phosphorus released was decreased with time in creased so the best result was 19.71 mgP kg^-1 at P2T2 treatment at 5 and 150 minutes(0.73mgkg^-1).

Abstract

The research aimed at estimating the production function and the total cost function, as well as measuring the efficiency of resource use, technical, economic, price and cost efficiency. The study was based primarily on a simple random sample of (155) farmers in Baghdad governorate for the autumn season (2015-2016), The double logarithmic formula was the most suitable for the production function. The resource efficiency criteria indicated that potato farmers were efficient in using resources (seed, phosphate fertilizer, human labor) and were inefficient in using irrigation and pesticides. Cubic formula was more suitable for the total cost function according to the statistical, econometrical, and economical tests., The optimum size of production and size that maximize profit were 119.069, 143.398 ton, respectively. Technical, economic and price efficiencies were estimated at 34.25933, 34.25937, and 73.521{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, respectively. While the cost efficiency was estimated at (0.454), and the net farm income that achieved over all the sample less about (10380.741) thousand dinars than that achieved at optimal size.

Abstract

This study was carried out during the period 25/1/2017 to 20/3/ at AL-Sader Teaching Hospital in Najaf 2018, to investigate the effects of the relationship between the leptin hormone and infertile men, leptin hormone and two hormone (insulin and testosterone ) and some demographic factors as age, weight, height and body mass index on leptin hormone. Fifty blood samples from infertile men and forty blood samples from fertile men were classified in to three aging groups ranged (20-35),(36-45) and (46-55) years ,the values of hormones (leptin ,insulin and testosterone) were examined to find out the correlation between hormone with each other and with infertile men. Significant differences were detected between (p≤0.05) in insulin and leptin levels. Besides significant reductions at (p≤0.05) in testosterone levels confined to age groups (20-35) and (36-45) in infertile men, as compared to fertile men. The result also revealed a positive relationship (p≤0.05) between the body mass index and leptin hormone.

Abstract

A field experiment was carried out at the Second Agricultural Research Station of the Faculty of Agriculture / Al-Muthanna University, located on the Euphrates River in Al-Bandar village, southwest of Al-Muthanna Governorate (800 m away from Samawah City Center / Muthanna Governorate) during the 2016-2017 winter season. Mixtures of forages. Medicago sativa L with a fixed seed quantity 40 kg ha^-1 with Triticosecal wheat each with 160 kg ha^-1 seed yield, for three levels of NPK (60, 100 and 140) kg ha^-1 and their overlap in growth, feed yield and four cuttings. The experiment was applied in fractional heiqht splitting design according to RCBD and three replicates.  The results showed significant superiority of the treatment (alfalfa singl)   higher by giving it the highest average of highe49.50 cm and number of branches 2092 branches and leaf area 44.50 m² plants^-1.  The treatmeant (alfalfa + tritical) was superiority of dry fodder yield (23.43) tons ha^-1 .As for fertilizer, it was significantly higher than 140 kg ha^-1 of dry feed yield (23.06) tons ha^-1  .In the interaction between the study agents, feed mixtures and fertilizer NPK, a variation was observed between the combinations within the mixture. The combination of alfalfa + tritical and the level of compost 140 kg ha^-1  in some characteristics of the quantitative and qualitative yield of the foliar mixture were recorded by recording the highest dry feed during the third tranche And 26.87 tons ha^-1) .
