Abstract
To study the effect of row space and pre-harvest treatment technique on yield, yield components and other characteristics of white mustard Sinapis alba L, an experiment was conducted in the field at the College of Agriculture, University of Baghdad/ Abu-Graib, using split plot design with three replications arranged in RCBD. The main treatments included three row space 20, 40 and 60 cm, while the sub-plot treatments included plants harvested at physiological maturity stage, plants harvested at full maturity stage, plants harvested at full maturity stage after GA3 application, and plants harvested at full maturity stage after Auxin application. The results obtained showed that row space of 60cm lead to significant increase in number of pods of plant, number of seeds of pod, weight of 1000 seeds, seeds yield of plant and biological yield of plant which were 486.31 pod.plant-1, 12.54 seed.pod-1, 1.74 g ,9.8 g. plant-1and 59.51 g.plant-1 respectively, as compared with row space of 20cm which gave least mean of 291.66 pods.plant-1, 10.90 seeds.pod-1, 1.59 g, 5.10 g.plant-1 and 27.42 g.plant-1 respectively. However these increases did not increase the total yield. Row space of 60cm lead to significant increase in percentage of field seeds germination 84.16% compared with row space of 20 cm which gave least percentage 76.58%, although there was no significant effects in percentage of laboratory seeds germination. Pre-harvest treatments did not affect number of pods in plant, number of seeds in pod and yield biomass. Treatment of plant harvested at full maturity stage after Auxin application lead to significant increase in weight of 1000 seeds, and yield of plant, while treatment of plant harvested at physiological maturity stage lead to significant increase in percentage of laboratory and field seeds germination. It was concluded that there was possibility of using some plants growth regulators to increase seeds plant yield, and if the purpose of planting to produce certified seeds, its prefer to harvest plants at physiological maturity for greater percentage of laboratory and field seed germination.
