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...
the high yield depends on high dry matter production per unit area. azotobacter bio-fertilizer experiment to investigate the effect on the index, total dry matter accumulation and pishtaz and chamran wheat cultivars in 2005 was conducted in the faculty of agriculture, lorestan university. experiment, a split-plot randomized complete blocks design with four replicates were tested. treatments con...
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...
Abstract Background Low soil fertility and reduced seasonal rainfall contribute to low potato ( Solanum tuberosum L.) yield in Kenya. Nitrogen (N) deficiency is the major problem facing by smallholder farmers of Kenya due lack fallow. Hence an introduction supplemental irrigation with adequate application this nutrient could increase yield. The objective study was determine effects N-fertilisat...
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 ...
In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...
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...
