Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication  in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...

introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...

this study was performed to assess the effects of nitrogen fertilizer and vermicompost on qualitative and quantitative yield of chamomile ( matricaria chamomilla l.). it was conducted at the research fields of ran company located in firouzkouh, iran, in 2013. treatments were consisted of 1) control, 2) 100% nitrogen from urea, 3) 100% nitrogen from ammonium nitrate, 4) 75% nitrogen from urea an...

application of organic fertilizers increases quality and yields in the sustainable crop production and considerably replaces or reduces chemical fertilizers. in order to study the effects of different manure and vermicompost rates on yield and essential oil contents of dragonhead, an experiment was conducted as a randomized complete blocks design with eight treatments and three replications in ...

The use of dry land for shallot cultivation in Indonesia is still not optimal because it considered as that has no good potential crop cultivation. Dry problems include limited availability water, low organic matter and soil nutrients, especially potassium. purpose this experiment was to determine the response vermicompost KNO3 fertilizer growth yield shallots on land. experimental design used ...

organic fertilizers such as vermicompost (vc) are an undeniable source of required nutrients of plants. this field experiment performed as split plot arrangement based a randomized complete block design with three replications in 2008. the main factors (vermicompost treatments) added to soil at six levels including 20 and 40 ton.ha-1, 20 and 40 ton.ha-1 plus (1/2) chemical fertilizer, chemical ...

Problem statement: Rapid urbanization and population growth are largely responsible for very high increasing rate of solid waste in the urban areas, its proper management and recycling is major problems of Municipal Corporation. Conversion of industrial wastes in to beneficial vermicompost not only solves solid waste accumulation but also yield highly nutritive organic manure. Approach: Enhanci...

BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...
