Effect of integrated weed management on growth and flowering of tuberose cv. Prajwal

Abstract

The present investigation entitled “Integrated weed management in tuberose (Polianthes tuberosa L.)” was conducted at Floriculture Research Farm, ASPEE College of Horticulture and Forestry. Navsari Agricultural University, Navsari (Gujarat) during the year 2017-2018. The experiment was conducted in Randomized Block Design (RBD) with three replications and eight treatments consisting of hand weeding, mulching and application of pre as well as post emergence herbicide. Among all treatments application of pendimethalin 1.0 kg/ha as PE + Organic mulch (sugarcane tress) after bulb sprouting and remulch at every 4 month interval (T5) was found most effective in average plant height 120, 240 DAP and at end of experiment (64.33 cm, 70.88 cm, and 73.05 cm, respectively), number of leaves per plant (128.80) and tillers per plant (13.33) at end of experiment (360 DAP), minimum days to spike emergence (98.80), maximum spike length (108.27 cm), number of florets per spike (46.80) as well as vase life (6.87 days). Dry biomass of plant (3.76 kg/plot) was also found maximum in the same treatment at end of experiment.
