A field experiments were carried out at Shambat, Sudan (Latitude 15 40 ́N and Longitude 32 o o 32 ́E) in three consecutive seasons (2000/03) to investigate the effect of Bradyrhizobium inoculation and chicken manure or sulphur fertilization on minerals composition of soybean (Glycine max L.). The results obtained showed that inoculation, chicken manure, sulphur and their interactions significantl...

in order to investigate the effects of fertilizer types and irrigation regimes on quantitative criteria of three medicinal plants: lavander, rosemary and hyssop, an experiment was conducted at research field of faculty of agriculture, ferdowsi university of mashhad, during two growing years of 2007-2010. a split-split plot design with three replications was used. treatments were three irrigatio...

The ability of Steinernema carpocapsae to reduce damage to seedling corn by the black cutworm, Agrotis ipsilon, in soil amended with three fertilizers (fresh cow manure, composted manure, and urea) was determined. Total nitrogen was standardized among the fertilizers at 280 kg/ha and 560 kg/ha. Black cutworm damage was assessed by the percentage of cut corn plants in small field plots. Relative...

Different strategies for Nile tilapia (Oreochromis niloticus) culture in ponds with a series of progressive inputs were compared. The sequential experimental stages to increase fish production through intensification were: 1) triple superphosphate (TSP) only; 2) chicken manure only; 3) chicken manure supplemented with urea or urea and TSP; 4) urea and TSP; 5) continually supplemental feeding; 6...

The application of organic fertilizers can improve soil fertility specifically on Inceptisol soils which are quite extensive but have problems with relatively low nitrogen nutrients so that the effort to overcome this is through addition matter into fertilization or inorganic fertilizers. purpose study was determine effect goat and urea fertilizer chemical properties inceptisols from Rantau Sel...

one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

Excessive use of animal manure on agricultural lands can impact the quality of surface and groundwater resources. A three–year study (1998–2000) was conducted on nine 0.4–ha plots and on six 2.1–m 2 lysimeters to investigate the effect of two nitrogen (N) application rates from laying hen manure and one N application rate from urea ammonium nitrate (UAN) fertilizer on surface and groundwater qu...

AIM To evaluate urea hydrolysis, volatile fatty acid (VFA) production (odour) and coliforms in cattle waste slurries after a urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) and a plant oil component (thymol) were added. METHODS AND RESULTS Faeces from cattle fed a diet of 70% corn silage and 30% alfalfa haylage, urine and distilled water in the ratio 50 : 35 : 15 were blended at h...

The cost of chemical fertilizers is increasing and becoming unaffordable for smallholders in Africa. present study aimed to assess the impact combined fertilization strategies using urea animal manure (beef cattle poultry litter manure) on rice yield nutrient uptake. For this, a field experiment was carried out loam sandy soil Chókwè Irrigation Scheme. We set seven treatments Randomized Complet...
