摘要

IMPROVING productivity of tuberose (Polianthes tuberose, L.) clump's bulb and bulblet yield and associated grade qualities, not only beneficial to tuberose growers and farmers, providing eventual ideal propagating propagules, but also useful to them by raising small bulblet cloves, for future sales and/or plantations, as prospective planting materials. 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 tuberose total bulb yield produced per clump, bulb & bulblet yield, and bulb & bulblets grade qualities during the 2001/2002 and 2002/2003 growing seasons. Irrigating tuberose plants every two days significantly increased total bulb yield, expressed as number per clump. It also increased large bulb yield, weight and size, in both seasons, to other watering frequency treatments. Appreciably, improved medium bulb performance, particularly, was shown in the second growing season. Also this treatment produced the highest yield of small bulblets or cloves, weight and size per clump, to other watering frequency treatments, in the two growing seasons.
