The study was conducted to investigate the effect of nitrogen application on the yield contributing characteristics, biomass yield and nutritive values of cowpea forage. Five nitrogen levels viz: 0 (T0), 15 (T1), 20 (T2), 25 (T3) and 30 (T0) kg N/ha were applied in 20 plots in a Completely Randomized Design (CRD). The result showed that the application of nitrogen fertilizer had significant (P<...

The experiment was conducted at the Agriculture Field laboratory of Noakhali Science and Technology University, Noakhali, Bangladesh during period from December 2020 to February 2021 observe effect different levels nitrogen (N) phosphorus (P) fertilizer on growth yield lettuce. comprised two factors. Two inorganic fertilizers like level viz; nitrogen-control 0 kgha-1 (N0), 100 (Nı), 150 (N2) 20...

Inceptisol soil is an agricultural land in Indonesia, which widely distributed, but has a problem, namely the element of N relatively low, so it necessary to carry out proper cultivation techniques, one through provision balanced fertilizers, organic fertilizers aim improve fertility and reduce use NPK fertilizer. This study aims determine effect various kinds sometimes goat urea fertilizer on ...

While the global increase in the use of nitrogen-based fertilizers has been well recognized, another change in fertilizer usage has simultaneously occurred: a shift toward urea-based products. Worldwide use of urea has increased more than 100-fold in the past 4 decades and now constitutes >50% of global nitrogenous fertilizer usage. Global urea usage extends beyond agricultural applications; ur...

nitrogen and phosphorus are two necessary macronutrients for plant growth and yield. these two elements now will be added to soil by chemical fertilizers. this research has been carried out based on randomized completely block design with three replications at markazi provience agricultural research station, iran, during growing season of 2004-2005 to evaluate the effects of azotobacter chrooco...

in this research, the effects of split application of nitrogen fertilizer on yield and yield component of three varieties of corn have been investigated. for this purpose, a split plot experiment on the base of randomized complete blocks in four replications was used. the main plots were three varieties of corn (370, 447 and 499), and sub plots were six split application of urea fertilizer trea...

In agriculture high urease activity during urea fertilization causes substantial environmental and economical problems by releasing abnormally large amount of ammonia into the atmosphere which leads to plant damage as well as ammonia toxicity. All over the world, urea is the most widely applied nitrogen fertilizer. Due to the action of enzyme urease; urea nitrogen is lost as volatile ammonia. F...

The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N) kg.ha-1 urea and wheat varieties, including cultivars, Sepahan and SW were placed in the subplots. Results showed that nitrogen fertilizer and cultivar were significant effects on ...

Enhanced efficiency nitrogen (N) fertilizers (EEFs) may improve crop recovery of fertilizer-N, but there is evidence that some EEFs cause a lag in crop growth compared to growth with standard urea. Biomass and mineral nutrient accumulation was investigated in rice fertilized with urea, urea-3,4-dimethylpyrazole phosphate (DMPP) and polymer-coated urea (PCU) to determine whether any delays in bi...
