چکیده
to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry flowers yield, plant dry-weight, number of inflorescence per plant, number of flower per inflorescence, plant height and flower length. the results indicated that effect of plant density on dry flowers yield, plant dry weight, number of inflorescence per plant, number of flower per inflorescence and flower length (p<0.01) and on plant height (p<0.05) was significant. planting pattern and interaction of plant density and planting pattern were not significant on the measured characteristics. the highest dry flower yield per unit area obtained in density of 6 plants m-2 (791.2 kg ha-1), while planting pattern did not significance affect on dry flower yield. also, the highest dry flower weight of single plant, plant dry weight, number of inflorescence per plant, number of flower per inflorescence, flower length and plant height obtained in density of 2 plants m-2.
