Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field ex...

effect of different amounts of sulfur fertilizer (0, 50, 100, 150, 200, 250 kg/ha) and 200 kg/ha of thiobacillus inoculant on yield, quality and storability of two edible onion cultivars red rey and white qom were investigated. the experiments were conducted at experimental field and laboratories of the department of horticulture, seed and plant improvement institute, karaj, iran in 2007-08 cro...

in order to study the effect of soil nitrogen content and water hardness on glyphosate efficacy on common lambsquarter (chenopodium album l.) and redroot pigweed (amaranthus retroflexus l.) control, an experiment was carried out as a completely randomized design in a factorial arrangement with three replications. experimental treatments were included soil nitrogen content (18, 50, 90, 200 and 3...

a study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (ocimum basilicum l.). the research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. the experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

this research was conducted to determine the effect of gamma ray (gr) (100 and 150 kgy), sodium hydroxide (50 g/kg dm) and calcium oxide (160 g/kg dm) on gas production parameters and in vitro digestibility of soybean straw. all treatments, except for the gamma ray (100 and 150 kgy) did not have gas production up to 4 hours after incubation and there was a lag time. from 8 to 96 hours of incuba...

the role of manure and urea on yield and some fruit characteristics of strawberry cv. kurdistan were studied during 2002-2004 growing season. the experiment was a factorial one based on a randomized complete block design including four levels of urea(0, 50, 100, 150 kg/ha) and three levels of manure (0, 20, 40 t/ha) in three replications. the results showed that application of manure along with...

Field and laboratory experiments were conducted to assess the response of wheat external auxin application nitrogen. Studied factors in field experiment different concentrations (0, 50, 100 ppm) nitrogen fertilizer 75, 150 kg/ha). In experiment, germination traits produced seeds from maternal plants under treatments assessed. Results showed that no with had higher stem leaf yield than 50 ppm kg...

Cultivation of sweet corn in Ultisols faces problems due to the poor quality soil. As a result, it is necessary improve soil fertility through fertilization. Chicken manure can Ultisol. However, prolonged-release fertilizer, so should be applied conjunction with readily available fertilizers plants, such as KCl. This study aimed determine effect dose chicken and KCl on growth yield corn. The wa...

The responses of litter decomposition to nitrogen (N) and phosphorus (P) additions were examined in an old-growth tropical forest in southern China to test the following hypotheses: (1) N addition would decrease litter decomposition; (2) P addition would increase litter decomposition, and (3) P addition would mitigate the inhibitive effect of N addition. Two kinds of leaf litter, Schima superba...
