The aim of this study was to investigate the effect of chemical fertilizers of nitrogen, phosphorus, sulfur and biofertilizer on some growth indicators of Camelina sativa L. experimental plant during the crop year 2016 in a farm located in Kazerun and as a factorial in the form of complete randomized block design with three replications. Treatments include fertile biofertilizer 2 containing pho...
ABSTRACT- To investigate the effects of bio-chemical and organic fertilizers on yield and seeds NPK contents of pumpkin (Cucurbita pepo var. styriaca), an experiment was conducted at the Research Farm of Kurdistan University in 2009 growing season. Treatments were included 1) control, 2) seeds inoculated with free-living N fixing bacteria (NFB), 3) seeds inoculated with phosphate-solubilizing b...
in order to investigate the effects of different levels of nitrogen and phosphorous fertilizers on flower yield , yield components and some quality components of german chamomile, a factorial experiment based on a randomized complete block design with four replications was carried out in the medicinal plant research farm of shirvan college of agriculture during growing season of 2007-2008. nitr...
In this work, chicken meat and bones (C-MBM) waste is treated through a sequence of stages including hydrothermal treatment (HTT), nutrient recovery anaerobic digestion, with the aim evaluating their potential synergy as circular economy approach. HTT was carried out at 170, 200 230 °C, under non-acidic acidic conditions using 0.5 M HCl (HTT-A). Phosphorous from process water recovered by chemi...
Recently, application of biofertilizers has been introduced as a new strategy in crop nutrition. In order to investigate the effect of application methods of biofertilizer in combination with nitrogen levels on yield and yield components of weed-infested triticale a field experiment was conducted at College of Agriculture and Natural Resources of Darab, Shiraz University in 2013-14 growing seas...
In order to study the effect of application of nitrogen, phosphorus and biologic fertilizers on yield and yield components of native bean, an experiment was conducted as factorial in randomized complete block design with three replications in Lahijan, northern Iran in 2013. Treatments consisted of chemical nitrogen fertilizer (0, 60 and 120 kg ha-1 urea), chemical phosphorus fertilizer (0, 40 a...
Abstract Introduction: Hospital wastewater including nutrients, nitrogen and phosphorous especially, that with discharge in environment result in problems in water ecosystem, animals and human health. Therefore, the aim of this study is determination of Nitrogen and phosphorous simultaneous removal from hospital wastewater by intermittent cycle extended aeration system (ICEAS). Methods: In...
Freshwater macroalgae represent a largely overlooked group of phototrophic organisms that could play an important role within an industrial ecology context in both utilising waste nutrients and water and supplying biomass for animal feeds and renewable chemicals and fuels. This study used water from the intensive aquaculture of freshwater fish (Barramundi) to examine how the biomass production ...
Objective: A field experiment was conducted at Dorud region, Iran, during 2013. The aim of this research was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (Beta vulgaris L.). Methods: The experimental design was factorial based on RCBD with three replications. Treatments were three irrigation closed time [Oct-6 (...
