این تحقیق به منظور مطالعه اثر تقسیط کود نیتروژن بر شاخصهای رشد و عملکرد سه هیبرید ذرت دانهای در شاهرود اجرا شده است. آزمایش به صورت کرتهای خرد شده در قالب طرح بلوکهای کامل تصادفی در چهار تکرار در سال زراعی 1386 به اجرا در آمده است. کرتهای اصلی شامل سه هیبرید ذرت (دبلکراس370، سینگلکراس447 و سینگلکراس499) و کرتهای فرعی شامل شش تیمار تقسیط کود نیتروژن (تیمار کودی اول (N1): 45 در شروع کاشت...
The effects of alachlor (2.25 kg a.i./ha) and fenamiphos (2.25 kg a.i./ha) on the penetration and development of Heterodera glycines were examined on Glycine max cultivars Deltapine 105 planted 29 April, 29 May, and 29 June 1986 and Deltapine 105 and Centennial planted 15 May, 15 June, and 15 July 1987. Penetration was lowest on the third planting of soybeans and on fenamiphos-treated plants. D...
The shelf-life of bread is influenced by flour components, such as starch, composed amylose and amylopectin. aim was to test the effect different balances N (45, 90, 135 kg/ha) P (48, 96 fertilizers on characteristics consequently PDO Tuscan bread, stored in modified atmosphere packaging (Ar, N2, Air). phytochemical compounds were increased decreased addition P, but excessive doses (135 had a n...
This study evaluated the effect of a fat blend containing long-chain (LC) n-3 PUFA on bone mineral density (BMD) and bone metabolism in gonad-intact middle-aged male rats (12 months old, n 28). Seven rats were killed on day 0 of dietary intervention to determine the baseline BMD. The remaining rats (seven per group) were fed a diet with one of the following dietary lipid treatments (g/kg diet):...
The nematicidal activity of the fungicide ethazole was studied under greenhouse conditions in which a nematode-infested, Norfolk sandy loam was planted to cotton (var. = 'Rowden'). At planting time, the fungicide was incorporated in the soil at rates of 0-100 mg/kg soil. When assayed 4 weeks after planting, plant-parasitic nematodes in soil and roots occurred in decreasing numbers with increasi...
Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...
To determine the nitrate pollution (water, soil, and tubers) in small (< 0.5 ha), medium (0.5- 1 ha) and large (> 1 ha) size of potato fields, this study was conducted in Fereidan region of Isfahan province during growing season of 2014-2015. For this purpose, the amounts of inputs and the tuber yield were recorded in each farm. Also, average nitrate-N concentration in irrigation water, soil an...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Relevance. At present, the issues of mineral nutrition medicinal plants with essential elements remain unstudied, and lack certain microelements in soils is an underestimated agroecological factor. This necessitates study effect different doses zinc copper fertilizers on content mobile forms meadow-chernozem soil when cultivating Achillea millefolium L. Tanacetum vulgare southern forest-steppe ...
This experiment was conducted at the Agricultural Research Station of Isfahan University of Technolgy in 2006 to evaluate the effects of planting pattern and the level of soil moisture on two safflower cultivars. A factorial split plot arrangement was used in a randomized complete block design with three replications. Two planting patternS (flat and bed planting) and two levels of soil moisture...
