Green bean (Phaseolus vulgaris L.) growth and yield as affected by chemical phosphorus fertilizer and phosphate bio-fertilizer

A field experiment was conducted at Khomam, Guilan province, northern Iran, to evaluate the effects of phosphorus rate and phosphate bio-fertilizer on growth and yield of green bean (Phaseolus vulgaris L.). The experimental design was a factorial arrangement of treatments based on a randomized compl...
