Application of organic manure in organic farming and long-term mineralization may lead to residual effects on the succeeding crop. So, residual effects of combined cattle manure and urea fertilizer of previous crop (black cumin) on growth and yield of pea were examined in a randomized complete block design. Treatments included of  cattle manure (CM), urea (U), three ratios of CM+U full dose app...

In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur  on some growth and yield components  of Camelina sativa L.,  a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...

  In order to determine the interaction of residual nitrogen (N) and different N rates on seed and oil yield of rapeseed, an experiment was conducted at Shahrekord University, Shahrekord, Iran, in 2008-2009 growing season. The experimental design was split plots arranged in randomized complete block design with three replications. Seven treatments of residual N (217, 435 and 652 kg/ha from urea...

In order to investigate the effects of municipal solid waste enriched with mineral fertilizers on some soil physical properties and lead (Pb) and chromium (Cr) concentration in plant organs of spinach, a field experiment was carried out in a factorial arrangement based on the randomized complete block design with three replications in 2008. The main plot included four levels of fertilizer, cont...

Reduction of chemical fertilizer consumption in the production of agricultural products, using bio-fertilizers as a suitable substitution or complementary for chemical fertilizers has privileges from ecology and economical aspects. The advantages of applying of bio-fertilizer are providing plant with different nutrients in accordance to the natural ability of plant, enhancing and improving soil...
