Abstract/ Executive Summary:

The experiment was conducted at the Spices Research Center, BARI, Shibganj, Bogura during 2009-10 to study the effect of different management practices to control of rhizome rot and best economic return on the growth and yield of ginger. Ginger cv. BARI Ada1 was planted 1st week of April. Six treatments were used viz., C1 (solarization of soil), C2 (burning of soil by rice straw), C3 (burning of soil by saw dust), C4 (neem cake), C5 (mustard oil cake) and C6 (control). The treatment was arranged in Randomize Complete Block Design using with three replications. The results reveled that C4 (neem cake) showed early emergence, highest plant height, number of leaves plant^-1 , number of tillers plant^-1 with maximum weight of primary rhizome and secondary rhizome, highest dry matter % and weight of old mother rhizome t ha^-1 . The highest yield of rhizome (18.02 t ha^-1 ) and best benefit cost ratio (2.25) was also recorded in the C4 (neem cake). From the results, it can be concluded that C4 (neem cake 2.0 t ha-¹ ) treatment produced higher yield and best benefit cost ratio for ginger cultivation in northern region of Bangladesh.

Keywords: Rhizome rot, Mustard oil cake, Neem cake, Economic return, Ginger

Location: Spices Research Centre, BARI, Bogura

Start Date: 01-04-2009

End Date: 24-01-2010

Program Area: Crop-Soil-Water Management

Commodity: Diseases, Ginger

Objectives:

To control rhizome rot disease and best economic return for ginger cultivation.

Methodology:

The experiment was undertaken in the farm of the Spices Research Centre, BARI, Bogura, during the period from April 2009 to January 2010. It has sub-tropical climate with an average annual rainfall of 237.13 mm. The soil is Tista polal tract, having a PH of 5.8-6.6. The field experiment was laid out in a Randomize Complete Block Design with three replications. Each plot measuring 4.0m long and 1.5m broad was prepared for each treatment. Transparent polyethene sheet was placed on the plot and soil was placed on the edges of each polyethene sheet to secure covering. The polyethene sheet was placed on the 1st February and removed after 4 weeks. Burning of soil by rice straw and sawdust (rice straw 0.75 kg m^-2 and sawdust 1.0 kg m^-2 ). Before planting soil was burn by rice straw and sawdust. Soil was covered by mulching materials maintains 7.5cm thickness followed by burning. The entire quantity of neem cake (2.0 t ha^-1 ) and mustard oil cake also (2.0 t ha^-1 ) were applied at the time of land preparation. Healthy ginger rhizome BARI Ada-1 variety was used and weight 40g per seed rhizome for planting material. Planting was done at 1st April. A uniform application of Cowdung, Urea, TSP, MP and Gypsum at 5 tons, 304, 267, 233 and 111 kg ha^-1 respectively was also made to all experiment area and other cultural operations was given according to the requirements of the crop. Total cowdung was applied at the time of general land preparation and the entire quantity of TSP, Gypsum and half of MP was applied during final land preparation. The half of the Urea was applied 50 days after planting and the remaining MP and Urea was applied in two equal splits 80 and 110 days after planting. Earthing up was done at 60, 90 and 110 days after planting. The crop was grown under rainfed condition, because farmers are generally ginger produced without irrigation. The data on different growth parameters was recorded from 10 selected plants 15 days’ interval randomly each plot at 50, 65, 80, 110, 125, 140 and 155 days after planting. Yield and yield contributing characters was collected at harvesting time. The collected data was analyzed statistically and adjusted with least significance (LSD) at 5% and 1% level of probability.

Achievement/Findings:

The highest benefit-cost ratio of 2.25 was recorded from the C4 treatment (neem cake) followed by 2.17 from C5 treatment (mustard oil cake). The lowest benefit-cost ratio of 1.42 was recorded from the C6 treatment (control). Considering the economic point of view, it can be concluded that the application of two-ton neem cake per hectare (C4 treatment) would be suitable for the production of ginger under Bogura, Bangladesh condition.
