Abstract/ Executive Summary:

A field experiment was conducted to study the effect of planting method and rhizome size on the growth and yield of ginger under the logistic support of the ‘Action Plan for Spices Project’ of BAU, at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh. The study comprised two factors viz. planting method and rhizome size. The main effects and the combined effects of three planting methods namely ridge method, furrow method and flat method with five rhizome sizes viz. 10-15g, 15-20g, 20-25g, 25-30g and 30-35g were evaluated. Planting methods and rhizome size and their combined effects showed significant influence on the yield and yield components of ginger. The highest yield (18.78 t/ha) was recorded from ridge method of planting followed by furrow (14.56 t/ha) and flat method (11.06 t/ha). The highest yield (19.64 t/ha) was recorded from 30-35g of rhizome size and the lowest (11.30 t/ha) was from 10-15g of rhizome size. The most satisfactory yield (22.78 t/ha) was found from the treatment combination of ridge method with 30-35g of rhizome size; while the poorest yield (8.34 t/ha) was obtained from the treatment combination of flat method with 10-15g of rhizome size.

Start Date: 00-06-2005

End Date: 25-12-2005

Program Area: Crop-Soil-Water Management

Commodity: Ginger

Objectives:

1. To determine the suitable planting method as well as optimum rhizome size of zinger.

Methodology:

The experiment was persuaded under the logistic support of the ‘Action Plan for Spices Project’ of BAU, at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh. The study consisted of the following treatments; planting methods: i) Ridge method (M₁), ii) Furrow method (M₂), iii) Flat method (M₃). Seed rhizome size: i) 10-15 g (S₁) ii) 15-20 g (S₂) iii) 20-25 g (S₃) iv) 25-30 g (S₄) v) 30-34 g (S₅). The two factor experiment was laid out in the Randomized Complete Block Design (RCBD) with three replications. The land was first divided into three blocks and then each block was divided into 15 unit plots. Thus, there were 45 unit plots in the experiment. The size of each unit plot was 3m x 2.4m. The treatments were then assigned randomly to the unit plots of each block so as to allot one treatment once in a block. The collected seed rhizomes were kept in underground soil before planting. The following doses of manure and fertilizers were applied as recommended in a report of Spices Research Centre, Bogra. Well decomposed cowdung - 5 ton, Urea - 304 kg, Triple super phosphate (TSP) - 267 kg, Muriate of potash (MP) - 233 kg, Gypsum -111 kg.The entire amount of cowdung was applied at the time of general land preparation and the entire quantity of TSP, Gypsum and half of MP were applied during final land preparation. The half of the urea was applied 50 days after planting. Remaining MP and Urea were used in two equal splits at 80 and 110 days after planting. Intercultural operation such as weeding, earthen up, insecticide and pesticide were done as and when necessary. The crop was harvested at a time on 25 December, 2005 when the leaves turned yellow and started to dry. Data on the following characters were collected from 10 plants, which were selected at random for each unit plot. Observations were made on emergence of seed rhizome, plant height, number of leaves per plant, number of tillers per clump, leaf length, leaf breadth, leaf area, weights of old mother rhizome, weights of primary and secondary rhizome per clump, yield per plant, dry weight of rhizome per clump, yields per plot and yield per hectare. The collected data were analyzed statistically and the means were compared with least significant difference (LSD) values.

Achievement/Findings:

The treatment combination of planting method and rhizome size exhibited significant variations on the yield components and yield of ginger. All the yield contributing components and yield showed highest value under the treatment combination of ridge method with the largest rhizome size and on the other hand, that was the lowest from the treatment combination of the flat method with the smallest rhizome size. Considering the situation of the present study, further investigation in different agro-ecological zones of Bangladesh for regional adaptability and other performances is suggested.
