An experiment was carried out at the Spices Research Sub-Center, BARI, Lalmonirhat during April/2011 to February/2012 to find out the effectiveness of liming for the production of ginger and suitable seed treating management practices against rhizome rot. The main effect of Liming level 2.0 t/ha gave the highest rhizome yield of 20.059 t/h with lower disease incidence. In case of management practice, hot water with fungicidal treatment and seed treatment only with fungicide produced highest rhizome yield (21.333 t/ha & 18.333 t/ha) with lower disease incidence. Combined effects also showed significant in respect of all parameter except plant height. The result of this study had shown lime application in the range 1.0 – 1.5 t/ha and seed treating management hot water with fungicide is a good compromise for yield with lower disease incidence.

To find out the effect of soil pH by liming and management practices by seed treatment.
The experiment was carried out at the Spices Research Sub-center, BARI, and Lalmonirhat during the period from April/2011 to February/2012. The soil of the experimental field was sandy-loam having soil pH of 5.62. The treatments comprised four liming level 1.0 t/ha, 1.5 t/ha, 2.0 t/ha and control and four management practice viz. fungicide treatment, hot water treatment + fungicide treatment, solarization treatment + fungicide treatment and control having split plot design with four replications. The liming and management practice assigned with main plot and sub-plot respectively. The total number of unit plot was 64 and the size of the unit plot was 2.8 m X 1.8 m and spacing 60 cm X 25 cm. Well decomposed cow-dung 5 t/h and the chemical fertilizer were applied as N140, P54, K117, S20 and Zn2 kg/ha. Total amount of cow-dung, P, S, Zn and half of K was applied during final land preparation. Half N of total N were applied germination after 50 days and the remaining N & K was applied into two equal split doses as side dress in 80 & 110 days after planting. Management practice hot water treatment at 510c for 10 minutes by giving required seed rhizome and solarised by keeping `ready for planting required seed rhizome pieces’ inside the transparent polytheen for two hours on the pucca floor or hard plain land before planting. The seed rhizome BARI Ada-1 was planting on 24 April, 2011. Harvesting of the crop was done on 26 February 2012. Data were collected on plant height (cm), no. of tiller/clump, no. of finger/clump, weight of finger/clump, rhizome yield (t/ha) and disease scoring. Disease scoring was estimated by (1 – 5) scale.

Based on the results it may be concluded from the above findings that highly acid soil affect on ginger cultivation due to long time survivalist of disease inoculums and untreated seed rhizome decreases yield due to higher disease incidence. Over all the different management practice with liming showed highest performance compared with control.
