An experiment was carried out on the fields of the college of Agriculture -Abu Ghraib, of a silty clay loam soil that has moisture of 15-16%, to study the effect of plowing and pulverization systems on some plant indicators of onion.The experiment included plowing systems with three levels (plowing with a moldboard plow, plowing by chisel plow and zero tillage plowing) as a primary factor.The second factor was that pulverization for only one time and repeating the pulverization twice through the use of the rotary tiller.The plant indicators of onion that are studied: plant length, onion diameter, onion weight and onion neck diameter.The experiment has carried out according to SPLIT PLOT design according to RCBD design by three replications.The results were statistically analyzed mean is tested in the least significant difference (LSD) p < 0.05 probability level.The results show that the moldboard plow recorded the highest average for each onion diameter of 5.7 cm, the length of the plant was up to 54 cm, the onion weight is 153.3 g and the highest average diameter of onion neck was 13 mm.The results show that the repeated pulverization twice recorded the highest average diameter of the onion at 4.8 cm, the highest average length of the plant up to 46.2 cm, the highest average weight of the onion was 133.6 g and the highest average diameter of the onion neck is 10.1 mm.The results of the research conclude the superiority of the moldboard plow and the repeated pulverization twice in giving the best indicators of vegetative growth and production of onion crop.
