Abstract/ Executive Summary:

The study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from May 2013 to February, 2014. The experiment consisted three levels of mulch: M₀ - control, M₁ -Rice straw mulch and M₂ - water hyacinth mulch. The experiment was laid out in a Randomized Complete Block Design (RCBD) with five replications. Application of different mulches showed significant variations on most of the parameters. The highest yield of spike (3,46,290/ha) was found from M₂ and the lowest (3,07,140 /ha) from M₀. So, water hyacinth mulch was found suitable for growth and yield of tuberose.

Program Area: Crop-Soil-Water Management

Commodity: Tube rose

Objectives:

The present investigation was undertaken with the following objective to determine the effect of mulching on growth, flowering and yield of tuberose.

Methodology:

The experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh. The location of the study site is situated in 23°74/N latitude and 90°35/ E longitude. The experimental soil belongs to the Modhupur Tract under AEZ No. 28. The selected experimental plot was medium high land and the soil series was Tejgaon. The climate of experimental site was under the subtropical, characterized by three distinct seasons, the monsoon or the winter season from November to February and the pre-monsoon period or hot season from March to April and the monsoon period from May to October. Bulbs of tuberose were used as planting materials and they were collected from Horticultural Farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka- 1207, Bangladesh. The experiment consisted three levels of mulch: M₀ - control, M₁ -Rice straw mulch and M₂ - water hyacinth mulch. The experiment was laid out in a Randomized Complete Block Design (RCBD) with five replications. There were 15 unit plots; the size of each was 2.0 m x 1.0 m. The experimental plot was opened in the first week of May 2013, with a power tiller and left exposed to the sun for a week. The sources of N, P₂O₅, K₂O as urea, TSP and MP were applied. The entire amounts of TSP and MP were applied during the final land preparation. Urea was applied in three equal installments at 30, 55 and 85 days after planting bulb of tuberose. The bulbs were planted on 20 May, 2013 with a distance on 20 cm x 20 cm and the number of bulb/plot was 50. Data of plant height, number of leaves per plant, days required for emergence of spike, percentage of flowering plant, length of flower stalk at harvest, length of rachis at harvest, number of spikelet per spike, number of spike per hectare, individual bulb thickness, individual bulb weight, individual bulb diameter, number of bulblet per plant, weight of bulblet, diameter of bulblets, bulb yield per plot and hectare, bulblet yield per plot and hectare were recorded from the sample plants during the course of experiment. Ten plants were randomly selected from each unit plot for collection of data. The experimental data obtained for different parameters were statistically analyzed. The mean values of all the recorded characters were calculated and analysis of variance was performed by ‘F’ (variance ratio) test. The significance of the difference among the individual and treatment combinations means was estimated by the Duncan’s Multiple Range Test (DMRT) at 5% level of probability.

Achievement/Findings:

The highest yield of spike per hectare (3,34,940) was observed from M₂ and the lowest yield (3,07,140) was observed from M₀. The highest diameter of individual bulb (2.05 cm) was found from M₂ and the lowest diameter (1.70 cm) was observed from M₀. The highest diameter of bulblet (1.36 cm) was found from M₂ and the lowest diameter of bulblet (1.21 cm) was attained from M₀. The highest yield of bulb per hectare (25.57 ton) was observed from M₂ and the lowest yield (18.38 ton) was attained from M₀. The highest yield of bulblet per hectare (22.38 ton) was found from M₂ and the lowest (17.28 ton) was found from M₀. So, water hyacinth mulch was found suitable for growth and yield of tuberose.
