Effects of irrigation frequency regimes and weed control management, on field grown tuberoses (Polianthes tuberosa, l), in the Saudi Arabian western region [electronic resource]: 1. clump growth & development, bulb yield, water use efficiencies and bulb nutrient contents.

Maximizing subterranean tuberose clump and bulb yield. as propagule(s) for farmers andlor growers, through weed control management and rational watering irequency regimes, is thoughtful investigation, particularly under the harsh arid zone environment, in the Saudi Arabian Western Region. A Split-Split-Plot field experiment, in Randomized Complete Block Design (RCBD), with four replicates, was conducted. to investigate the effects of different irrigation frequency regimes; irrigation every 2, 4, 6 and 8 days, comprising the whole plots; manual hand weeding (unweeded control, weeding every 4, 8, and 12 weeks) representing the sub-plots; and herbicidal treatments (control, pendimethalin, glyphosate and pendimethalin plus glyphosate) allocated for the sub-sub-plots, on tubcrose vegetative growth, clump growth characteristics, accompanicd bulb & bulblet yield, water use efficiencies and nutrient contents in bulb tissues, during the 2001/2002 and 2002/2003 growing seasons.
