Abstract/ Executive Summary:

The experiment was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, during October 2011 to March 2012 to study the influence of different organic manures on growth and yield of broccoli. Experiment consisted of three levels of organic manures, viz. O₀ = Control; O₁ = Cowdung (25 t ha^-1) and O₂ = Spent Mushroom compost (17 t ha^-1) and was laid out in randomized complete block design with four replications. The highest plant height, number of leaves, leaf length, leaf breadth, days required for curd initiation, crown length, diameter and weight of primary curd plant^-1, number and weight of secondary curds plant^-1 and yield (16.99 t/ha) were obtained from spent Mushroom compost (O₂) while the lowest (9.14 t ha^-1) from control (O₀).

Keywords: Broccoli, Organic manure, Growth and yield attributes.

Location: Modhupur Tract

Start Date: 01-10-2011

End Date: 31-03-2012

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To investigate the performance of different organic manures on growth and yield of broccoli.

Methodology:

The experimental area is geographically located at 23^o41 N latitude and 90^o22 E longitudes at the elevation of 8.6 m above the sea level. Soil of the experimental field was silty loam in texture belongs to the Modhupur Tract under the AEZ No. 28 (FRG, 2012). The climate of the experimental site was under the subtropical climate, characterized by winter season from November to February. The experiment was laid out in randomized complete block design with four replications using three levels of organic manures control, cowdung (25 t ha^-1) and spent Mushroom compost (17 t ha^-1). Hybrid variety of broccoli (Early green) was used as planting material. The size of the each plot was 2.5m × 2.4m. The distance maintained between two blocks and two plots were 1 m and 0.5 m respectively. The plots were raised up to 10 cm. Twenty five days old healthy seedlings were transplanted at the spacing of 60 cm × 50 cm in the experimental plots on 24 November 2011. Only organic manure was used as the source of nitrogen, phosphorus and potassium. Total amount of organic manure was applied during final land preparation as per treatment. Intercultural operations were done on need based conditions of the crop. The data pertaining to following characters were recorded from ten plants randomly selected from each plot except yield of curds which was recorded plot wise. Plant heights, number of leaves per plant, leaf length, leaf breadth were measured at 20, 40 and 60 days after transplanting (DAT). Data on yield components viz. days required for 80% curd initiation, crown length, Diameter of primary curd, weight of primary curd, number of secondary curds per plant, average weight of secondary curds, yield per plant and yield per hectare were also recorded. All the data were statistically analyzed using the computer package program, MSTAT-C. The mean values of all the treatments were calculated and analyses of variance for all the characters were performed by the F-test (variance ratio). The significance of the difference among the treatment combinations of means was estimated by least significance difference (LSD) at 5% level of probability.
