Abstract/ Executive Summary:

The experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during the period from April, 2009 to March, 2010 to investigate the effect of potassium levels on growth, flowering and bulb yield of tuberose. The experiment consisted of four levels of potassium i.e. K₀: 0, K₁: 170, K₂: 180 and K₃: 190 kg K2O ha^-1. Results showed that potash application significantly increased the number of leaves plant^-1, leaf length, leaf breath, number of side shoots plant^-1; and bulb and flower attributes. Significantly the highest flower (16.4 t ha^-1) and bulb (22.0 t ha^-1) yields were noted in K₃ whereas the lowest flower (11.5 t ha^-1) and bulb (17.2 t ha^-1) yields were recorded in K₀.

Keywords: Fertilizer, K2O, Polianthes tuberose

Location: Horticultural farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka

Start Date: 00-04-2009

End Date: 00-03-2010

Program Area: Crop-Soil-Water Management

Commodity: Tube rose

Objectives:

To investigate the effect of potassium levels on growth, flowering and bulb yield of tuberose.

Methodology:

The experiment was conducted at Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from April, 2009 to March, 2010. The experiment consisted of different levels of potassium, namelyK₀: 0, K₁: 170, K₂: 180 and K₃: 190 kg K2O ha^-1in a randomized completely block design with three replications. Full dose of cow dung (20 t ha^-1), and TSP were incorporated during final land preparation. The total dose of nitrogen from urea and potash (as per treatment) were applied in three equal installments. The first installment was applied at 30 days after planting. The second and third installments were applied at 65 and 100 days, respectively after planting. Bulbs of tuberose cv. Double were used from Horticulture Farm of Sher-e-Bangla Agricultural University. Uniform bulbs (2.0 to 3.0 cm in diameter) were selected for planting. The planting distance was 25 cm x 25 cm between row to row and plant to plant. Data were collected on different growth and yield related parameters and analyzed statistically following the analysis of variance (ANOVA) technique. The mean differences were adjudged by Duncan’s Multiple Range Test (DMRT) using the MSTATC statistical computer package program.

Achievement/Findings:

A high dose of potassium has a positive effect on growth and development of tuberose. For better production of bulb and flower, potassium could be applied @ 190 kg K₂0 ha^-1.
