Abstract/ Executive Summary:

A field experiment was accomplished in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2018 to March 2019 to study the influence of starter solution and mulching on the growth and yield of broccoli. The experiment comprised of four levels of starter solution viz., S₀(Control), S₁(1% Starter solution), S₂(1.5% Starter solution) and S₃(2% Starter solution), and four levels of mulching viz., M₀(no mulch), M₁(Black polythene), M₂(Water hyacinth) and M₃(Rice straw) were used in this experiment arranged in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield attributes parameters were taken in which all the treatments showed significant variations. In the case of starter solution, maximum plant height (71.41 cm), number of leaves (15.35), canopy spread (78.86 cm), and weight of primary curd (416.41 g) were recorded from S₃(2% urea solution) treatment. In the case of mulching, maximum plant height (73.02 cm), number of leaves (16.00), canopy spread (80.81 cm), and weight of primary curd (442.24 g) were recorded from M₁(Black polythene) treatment. The highest yield (19.67 t/ha) was recorded from S₃(2% Starter solution) whereas the lowest yield (14.83 t/ha) was obtained from S₀. A significantly higher yield (21.00 t/ha) was recorded from M₁(Black polythene) while the lowest yield (12.88 t/ha) was obtained from M₀ treatment. In the case of the combined effects, the maximum yield (24.07 t/ha) was recorded from the treatment combination of S₃M₁while the lowest yield was (11.87 t/ha) recorded from S₀M₀treatment. It was apparent from the above results that the treatment combination of S₃M₁was more suitable for farmers than the rest of the treatment combinations

Program Area: Crop-Soil-Water Management

Commodity: Mulching, Broccoli

Objectives:

To finding Influence of Starter Solution and Mulching on Growth and Yield of Broccoli.

Methodology:

The experiment was conducted at the Horticulture Farm of Sher-e- Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during the period from October 2018 to February 2019. The experimental site was located at an elevation of 8 meters above sea level in the Agro-ecological zone of "Madhupur Tract" (AEZ-28), The soil was sandy loam and medium high land in texture with the pH value of 5.62. The research consisted of two factors: Factor A: Starter solution (urea solution at four levels) as- S = 0% Starter solution (control) S = 1 % Starter solution, S₂= 1.5% Starter solution S₃= 2% Starter solution and factor B: Mulching (four levels) as- M₀ =No Mulching (Control) M₁= Black polythene M₂=Water hyacinth M₃=Straw. The two factors experiment was laid out following Randomized Complete Block Design (RCBD) with three replications. The experiment was divided into three equal blocks where each block was divided into 16 plots. Then 16 treatment combinations were allotted randomly in each block. The size of each unit plot was 1.8 m × 1.2 m. The distance maintained between two blocks and two plots were 0.7 m and 0.5 m, respectively. The seedlings were transplanted with maintaining distance row to row 60 cm and plant to plant 40 cm. The seedlings were treated with starter solution just before being transplanted. The roots of the uprooted seedlings were merged into starter solution just for a while (about 5 minutes) and then immediately transplanted. Black polythene was spread on the plot just before transplanting where water hyacinth and rice straw were used as mulch materials just a week after transplant. The data obtained for different parameters were statistically analyzed by the MSTAT-C computer package. The significance of the difference among the treatment combinations means was compared by LSD test at a 5% level of probability.

Achievement/Findings:

Considering the above result of this experiment, the following conclusion and recommendation can be drawn: 1. The application of 2% urea solution showed better performance for almost all the parameters in broccoli production. 2. Black polythene gave the best results for both vegetative growth and yield of broccoli. 3. It can be concluded that a combination of 2% urea solution and black polythene mulch is better for broccoli cultivation
