Abstract/ Executive Summary:

The experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University, Bangladesh during the period from October 2011 to March 2012 to find out the response of broccoli to different organic manures. The experiment consisted four different organic manures viz. M₀: Control i.e. no manure application; M₁: Cowdung @ 15 t/ha; M₂: Poultry Manure @ 12 t/ha and M₃: Vermicompost @ 13 t/ha following Randomized Complete Block Design with three replications. Maximum weight of primary curd (484.7 g), diameter of primary curd (10.0 cm), number of secondary curd (3.0), weight of secondary curd (76.7 g), dry matter content of leaves (13.9 g), dry matter content of curds (13.1 g), yield/plot (11.2 kg) and yield/hectare (12.0 ton) were found from M₂ while minimum from M₀.

Objectives:

Objective of the study was to find out the response of broccoli to different organic manures.

Methodology:

The experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2011 to March 2012 to study the effect of organic manures on growth and yield of broccoli. Experiment consisted of four treatments viz. M₀: Control i.e. no manure application; M₁: Cowdung @ 15 t/ha; M₂: Poultry Manure @ 12 t/ha and M₃: Vermicompost @ 13 t/ha using Randomized Complete Block Design with three replications. Premium cultivar was used in the experiment. Each block was divided into 4 plots where 4 treatments were allotted at random. There were 12 unit plots altogether in the experiment. The size of the each plot was 2.25 m × 2.4 m. The distance maintained between two blocks and two plots were 1.0 m and 0.5 m respectively. Cowdung, poultry manure and vermicompost were applied as per treatment as a basal dose. 23 days old healthy and uniform seedlings were transplanted in experimental plots on 18^th November, 2011. Seedlings were planted in the plot with maintaining distance between row to row and plant to plant was 60 cm and 45 cm respectively. For the data collection, five plants were randomly selected from each unit plot except yields of curds, which was recorded plot wise. Data were collected on plant height, number of leaves/plant, days to first visible curd, length of stem, diameter of stem, fresh weight of leaves/plant, length of root, fresh weight of roots/plant, weight of primary curd, diameter of primary curd, number of secondary curd, weight of secondary curds, dry matter content of leaves, dry matter content of curd, yield/plot and yield/hectare. Only the compact mature curds were harvested with 15 cm long fleshy stalk by using as sharp knife. The curds were harvested in compact condition before the flower buds opened. Before harvesting of the broccoli head, compactness of the head was tested by pressing with thumbs. After harvesting the main curd, secondly the shoots were developed from the leaf axils, which also developed into small secondary curds and were harvested over a period of time. For the dry weight, at first 100 gm samples of selected plant was collected, cut into pieces and was dried under sunshine for a few days and then dried in an oven at 70^oC for 72 hours before taking dry weight till it was constant then dry weight was recorded with a beam balance. Collected data were statistically analyzed by using MSTAT-C computer package program. The mean values were evaluated and analysis of variance was performed by the ‘F’ (variance ratio) test. The significance difference among the treatments was estimated by Duncan’s Multiple Range Test (DMRT) at 1% level of probability.

Achievement/Findings:

Poultry manure (12 ton/ha) was the best for the broccoli production. As vermicompost (13 ton/ha) had statistically similar response to the broccoli production so farmers can use vermicompost also concerning the availability and economic concern of the vermicompost and poultry manures.
