Abstract/ Executive Summary:

An experiment was conducted at Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October-December, 2007 to study the effect of different organic manures on growth and yield of kohlrabi plant. Three types of organic manures viz., were compared with control (no manure) in the experiment. The maximum plant height (36.50 cm), plant canopy (63.50 cm), leaf length (30.42 cm), leaf breadth (14.25 cm), fresh leaves weight per plant (131.10g), diameter of knob (8.23cm), Knob weight (366.60 g), yield per hectare (22.90 t ha G¹ ) were found in poultry manure application. Only the maximum number of leaves (20.00) was found in control treatment. On the other hand the minimum plant height (32.25 cm), plant canopy (55.75 cm), leaf length (24 .92 cm), leaf breadth (10.75 cm), fresh leaves weight per plant (86.97g), diameter of knob (7.95 cm), Knob weight (177.50 g), yield per hectare (15.40 t ha G¹ ) were found in control treatment. Minimum number of leaves (14.33) was found with cowdung application.

Keywords: Cowdung, Poultry manure, Vermicompost, Yield

Location: Horticulture Farm in Sher-e-Bangla Agricultural University, Dhaka-1207

Start Date: 00-10-2006

End Date: 00-12-2007

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To evaluate the growth and yield performance of kohlrabi cultivar (Sufala) under different organic manures.

Methodology:

The experiment was conducted at Horticulture Farm in Sher-e-Bangla Agricultural University, Dhaka-1207 during October 2007 to December 2007. The area had sub tropical climate characterized by high temperature (28°-32°C) accompanied by moderately high rainfall during Kharif (April-September) season and low temperature (15°-20°C) in the Rabi (October-March) season. The soil belongs to the “Madhupur Tract”, AEZ-28. Soil pH ranges from 5.4-5.6 and have organic carbon 0.82 %. The experiment was laid-out in Randomize Completely Block Design (RCBD) with five replications. Four types of organic manures viz., OM₀= Control (no manure), OM₁ = Cowdung (30 t haG¹), OM₂ = Poultry manure (25 t haG¹) and OM₃ = Vermicompost (20 t haG¹) were used in the experiment. A high yielding kohlrabi cultivar ‘Sufala” was used in this study. The seeds were sown on October 9, 2007 on raised bed maintaining the spacing of 45 cm × 30 cm. Irrigation and weeding was done at ten days interval. Other intercultural operations and pest management was done as per recommendation and whenever necessary. Randomly selected ten plants were harvested from each plot for data collection. Data were collected on plant height (cm), plant canopy (cm), number of leaves per plant, Leaf length (cm), leaf breadth (cm), weight of leaves per plant, Diameter of knob (cm), knob weight (g), yield (t haG¹). The means were separated by DMRT at 5% level of significance.

Achievement/Findings:

The increase in the total yield resulting by organic manuring may be attributed to that organic manuring enhanced soil aggregation, soil aeration and increasing water holding capacity and offers good environmental conditions for the root system of kohlrabi plants. Poultry manure is rich in its nitrogen and nutrients content. These favorable conditions creates better nutrients absorption and favors the growth and development of root system which in true reflects better vegetative growth, photosynthetic activity. Consequently higher total yield would be obtained by poultry manure. The reports recorded by other investigators.
