DEVELOPMENT OF PACKAGE TECHNOLOGY FOR GINGER PRODUCTION IN BANGLADESH

Abstract

The present research work was conducted at the Spices Research Centre, Bangladesh Agricultural Research Institute, Shibgonj, Bogra during the period 2008-09 to 2010-2011 to develop technology package for higher ginger production. Series of experiments were conducted in relation to rhizome size, plant spacing, planting time, mulching, irrigation, planting method, nitrogen and potassium fertilizer application and rhizome rot control for ginger production.

Results revealed that 50g rhizome gave highest yield but the economic size was 40g for ginger production. The maximum yield was obtained from the high plant density. It gave the highest rhizome yield by increasing plant population per unit area, and lower density (50 × 25cm) reduced rhizome yield per unit area due to less plant population. But from the economic point of view, 40 × 25cm spacing was the significantly best for ginger production. In case of planting time 1st April planting the was best for ginger production. Rice straw mulch with two irrigations was the best for ginger production. Ridge method was found suitable for ginger cultivation than the flat planting method. In case of fertilizer, nitrogen applied at 120 and potassium at 120kg ha─1 were observed to be the optimum for obtaining higher ginger yield. Neem cake at a rate of 2 t ha─1 was better to control rhizome rot and ginger production. Based on the results of the experiments, a technology of package for ginger production has been suggested. The suggested technology package includes: 40g seed rhizome, 40 × 25cm spacing, 1st April planting, rice straw mulch, two irrigation, ridge planting method, nitrogen application at 120kg and potassium 120kg ha─1 and neem cake at 2 t ha─1 for growing ginger under Bogra, Banglabesh condition.
