Influence of weed management on vegetative growth, flower and bulb parameters of tuberose

Abstract

A field experiment was conducted at the AICRP on Floriculture Unit, Horticulture Farm, Department of Horticulture, Rajasthan College of Agriculture, Udaipur. The experiment consisted with fourteen treatments comprising of hand weeding, herbicides and weedy check replicated thrice in randomized block design. Among the various weed management practices tested, out of them pre-emergence application of pendimethalin @ 0.75 kg a.i./ha + 1 hand weeding (HW) at 40 days after planting (DAP) reported lowest weeds counts at 50 DAP (13.1 m-2), fresh weight (20.83 g) and dry weight of weeds (3.28 g) with maximum weed control efficiency (93.10 %) as compare to weedy check. However, 3 HW at 30, 60 and 90 DAP had superior effect on the plant height (89.36 cm), leaves/plant (51.76), spike length (78.52 cm), spike emergence (110.68 days), first flowering (116.44 days), floret/spike (47.97), spike/plant (4.81), flower weight/plant (138.47 g), flower diameter (4.49 cm), flower duration (26.17 days), spike durability in field (20.60 days), bulbs/plant (16.43), bulb diameter (3.85 cm), fresh weight of bulb (28.49 g), bulblets ha-1 (33.39) and fresh weight of bulblet (3.37 g) followed by pendimethalin @ 0.75 kg a.i./ha + 1 HW.
