Effect of weed control treatments on weeds, vase life and yield parameters of tuberose (Polianthes tuberosa L.)

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. In the present investigation the pre emergence application of pendimethelin @ 1 kg/ha showed significantly lowest weed population, fresh weight and dry weight of weeds with highest weed control efficiency at 25 DAP (17.51, 25.07 g, 7.25 g and 82.69 % m-2) and pendimethelin @ 0.75 kg/ha + 1 HW (at 40 days), at 50 DAP (13.80, 21.70 g, 3.65 g and 92.38 % m-2), while the 3 HW at 30, 60 and 90 days interval at 75 DAP (8.39, 19.30 g, 4.82 g and 90.19 % m-2) as compared to other treatments. Whereas, 3 HW at 30, 60 and 90 DAP had superior effect on the vase life (8.83 days), water uptake (59.91 ml), flower yield ha-1 (9,566 kg), spike yield ha-1 (338000) and bulb yield ha-1 (740491). After the hand weedind, pendimethelin @ 0.75 kg/ha + 1 HW at 40 days had superior effect on vase life and yield parameters as compared to other treatments.
