Due to yield increase, some farmers in Iran plant sugarbeet in 50-cm row spacing instead of conventional 60-cm row spacing. Low row spacings force farmers to harvest three consecutive rows instead of two alternate rows. This would increase the amount of draft requirement to pull the lifter through the soil. In order to use common medium tractors for pulling the three-unit sugarbeet lifter and p...

In order to investigate the effect of planting arrangement on growth indices and grain yield of a red bean cultivar (Sayyad cultivar), The experiment was conducted in a split-plot randomized complete block design with 4 replications in Jihad Agricultural Services Center of Al-Mahdi town, Azna. The main factor consisted three row spacings including 20, 30 and 45 cm and the sub-factor consisted t...
