A pot experiment was carried out at screen house, Faculty of Agriculture University Maiduguri to compare the effect NPK, bio-fertilizers and manures applications on growth nutrient uptake by maize. The consisted 9 treatments combined application NPK half full recommended rates for maize, Azotobacter chroococcum, Bacillus megaterium Pseudomonas fluorescence biofertilizers cow dung poultry replic...

In case of a nuclear accident, decision makers rely on high resolution and accurate information about the spatial distribution of the radioactivity levels in the surroundings of the accident site. Static nuclear monitoring networks are therefore employed in many countries in Europe. However, these networks were designed to cover the whole country and are usually too course to reach a high densi...

Field experiments were conducted at Government Adaptive Research Farm Karor Lal Eason, districtLayyah, to study the impact of trace elements on uptake of nitrogen, phosphorus, potassium and yield of wheat. The experiments were laid out in RCBD having three replications. Soil samples were collected before sowing of crop from 0-15 cm depth and analyzed for physical and chemical properties (textur...

In order to study the effects of nitrogen (N), phosphorus (P) and potassium (K) on the yield, the appearance eligibility ratio and the contents of total glucosinolates and glucoraphanin of cauliflower, the 311-A optimization regression design was used to conduct field experiments of N, P, K fertilizer treatments using winter cauliflower variety ‘‘HB16’’. The models of the balanced application f...

Enhancing cereal crop production to feed the largely growing population is an important approach towards maintaining food security. Fertilizer management major component of requiring special attention for sustainable application. Integrated nutrient (INM) evolving idea, which appears contribute management. A field study was designed see impact INM on a maize–wheat cropping system during winter ...

To study vegetation feedbacks of nutrient addition on carbon sequestration capacity, we investigated vegetation and ecosystem CO2 exchange at Mer Bleue Bog, Canada in plots that had been fertilized with nitrogen (N) or with N plus phosphorus (P) and potassium (K) for 7-12 years. Gross photosynthesis, ecosystem respiration, and net CO2 exchange were measured weekly during May-September 2011 usin...

Annual nitrogen (N), phosphorus (P), and potassium (K) flows in agriculture in The Netherlands were identified and quantified in 1990, with special emphasis on pig production. Also, the effects that various management strategies in pig production have on NPK emission in 1990 were compared using a static deterministic simulation model. Ammonia emission from pig production in 1990 (60.9 Gg N) exc...

A field experiment was conducted under a wheat-maize rotation system from 1990 to 2006 in North China Plain (NCP) to determine the effects of N, P and K on yield and yield gap. There were five treatments: NPK, PK, NK, NP and a control. Average wheat and maize yields were the highest in the NPK treatment, followed by those in the NP plots among all treatments. For wheat and maize yield, a signif...
