Abstract/ Executive Summary:

In a two year field experiment in the south eastern piedmont soils (pH 5.0-5.5) at the Regional Agricultural Research Station, Hathazari, Chittagong the effect of liming on rice and its subsequent effect on the yield of cabbage was tested. Lime was added as basal at 0, 2.5 and 5.0 /ha on rice and also on cabbage before land preparation. There was no significant effect of Iime On the yield or rice for both years although the pH level increased from 5.3 to 0.6. However, addition or lime increased cabbage yield up to 33% irrespective or time of application. There was no significant difference between 2.5 and 5.0 t/ha or lime indicating that 2.5 t/ha or lime wax sufficient to get a good yield or cabbage if applied before rice or before cabbage transplantation in the piedmont soiIs or Chittagong.

Keywords: Rice, Cabbage, Acid soil

Location: Regional Agricultural Research Station, BARI, Hathazari, Chittagong

Start Date: 00-00-1987

End Date: 00-00-1989

Program Area: Crop-Soil-Water Management

Commodity: Cabbage, Rice

Objectives:

To study the effect of different rates of liming both before and after rice crop on the yield of subsequent crop as well as of rice.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, BARI, Hathazari, Chittagong during 1987-88 and 1988-89 growing seasons. The soil representing Northern and Eastern Piedmont plains was silt loam in texture and inherently acidic (pH 5.0 to 5.5). The experiment was laid out in randomized block design with four replications. During 1987-88, rice (var. BR 14) was transplanted at 20cm x I0cm spacing in plots of 6m x 5m on August 31 and during 1988-89, rice variety BR II was transplanted on July 31 with same spacing and plot size. In each case, lime (CaCo₃) was used during final land preparation on individual plots as per design and layout at 0,2.5 and 5.0 t/ha on rice (R) and at different combinations on cabbage (C) in the same layout viz R_oC_o, R_OC_2.5, R_2.5 C_2.5, R_5.0,C_oand R_oC_5.0, in 1987-88 and in 1988-89, one more treatment R_2.₅C_O was added.Blanket application of fertilizers were made in the rice at 80, 60, 20 and 3 kg/ha of N, P₂0₅, K₂o, Sand Zn from urea, TSP, MP, gypsum and zinc oxide respectively. Intercultural operations including crop protecting measures were done as and when necessary. At maturiy, data on yield components of rice were taken. After harvest of rice, land was again prepared for cabbage crop as per design and during land preparation, 80 kg p₂O₅, and 40 kg K₂O/ha were added. Nitrogen at 200 kg/ha was applied in two equal splits as side dressing on 15th and 35th day after transplanting of cabbage and was incorporated to the soil.Thirty days old cabbage seedlings (var. Atlas 70) were planted on December 06 during 1987-88 and on November 15 during 1988-89 at 60 cm x 45 cm spacing. Irrigation, earthing up and plant protection measures were carried out as and when necessary. For both the years harvesting of cabbage was started 90 days after planting and continued till I 10 days. Individual weight, cumulative total yields were recorded. Soil sampling was done from individual plots before and after planting of rice and cabbage. Samples were analysed for chemical changes in soil due to liming. Data were analysed statistically, and only the significant means were subjected to LSD test.

Achievement/Findings:

That liming on rice for increased yield of subsequent cabbage is possible. This can also increase the turnaround time after rice harvest, and liming at 2.5 t/ha can be enough for a good yield of cabbage in the Piedmont soils of Chittagong. However, liming is not necessary for a good crop of rice.
