Abstract
the objective of this investigation was to study the effect of irrigation regimes .every 12 days interval, 15 days and 18 days intervals), plant densities 25 000, 30000, 35000 plant. fed.. and biofertilizers (2 bags of cerialen/fed., 2 bages of cerialen + 40 kg N/fed., 1 bags cerialen + 60 kg N/fed. And 80 N/fed.) on some agronomic characters of sugar beet.
The experiment was designed in split split plot design with there replications, where the irrigation regimes were allocated in main plots and plant densities were designed in sub plots and biofertilizers treatments were designed in sub plot.
