Abstract:

Planting arrangement through the plant’s phonological traits affect on plant yield. In order to the experiment was done in factorial randomized complete block design with three replicates in 2010 in Kermanshah Mahidasht. In this experiment the three row intervals of 25, 35 and 45 cm plant intervals and three rows 10, 15 and 20 cm were compared. The results showed that the effect of row interval and plant interval on the row on the number of days to heading, the number of days to flowering, the number of days to maturation and the number of days to economic yield was significant. By reducing the row intervals, plant interval on the row, the number of days to flowering decreased,. The grain yield decreased by increasing the planting row interval from 25 cm to 45 cm. The row intervals and plant intervals on fewer rows by the reason of homogeneous plant distribution; vegetation has been completed faster and used of maximum sunlight and environmental factors. The maximum grain yield in per unit area was of 30 cm row interval and 10 cm plant interval on row, respectively. The increasing grain yield relates to the shortening days to maturate, does not encounter the plant with water stress and better use of environmental factors.
