Effect of mulch on potato cultivation in saline area under rainfed condition was studied at CDSP II site, Char Majid, Noakhali during rabi season in 2003-2004. Potato variety “Diamond” was tested with three mulch materials viz. Water hyacinth (M1), Rice straw (M2), Rice husk (M3) and one control no mulch (M0). Significant variation was found among the mulch materials on potato yield. All the mulch materials showed better yield performance in comparison with no mulch. The highest yield (8.16 t/ha) was found with rice straw mulch followed by water hyacinth (8.06 t/ha) while the lowest was resulted with no mulch (3.99 t/ha).

To assess the effect of mulch materials on potato cultivation in saline area.
The experiment was conducted at farmers’ field under Char Development and Settlement Project - II (CDSP - II) site, Char Majid, Noakhali, during the winter season of 2003-2004. The soil was silt loam to clay under the Ramgati soil series of AEZ 18 (Young Meghna Estuarine Flood plain). Potato variety “Diamond” was tested with three mulch materials viz. Water hyacinth (M1), Rice straw (M2), Rice husk (M3) and one control; no mulch (M0). The experiment was conducted under randomized block design with five replications having unit plot size of 5m x 2m. The crop was fertilized with N-P-K (100-24-100 kg/ha). All fertilizers were applied at the final land preparation as basal. The whole potato tubers were planted within 14-20 December 2003 with 60cm x 25cm spacing. Mulches were applied immediately after planting to check the loss of soil moisture. Harvesting was done from March 7 to 21, 2004. All the data were recorded at the time of harvest and were statistically analyzed. The means were compared by Duncan’s Multiple Range Test (DMRT).
Annual Research Report 2003-04 published by OFRD, BARI
Mulch materials have great influences on plant height, number of tuber/hill, tuber weight/hill and tuber yield (Table 1). The highest plant height (41.60 cm) was recorded from the plants mulched with rice straw while the lowest plant height (34.26 cm) was recorded from no mulch. Highest number of tubers produced per hill (6.42) by the plants mulched with rice straw. Tuber weight per hill was not significant but tuber yield was highly influenced by mulch materials and the highest tuber yield (8.16 t/ha) was recorded from the crop covered with rice straw mulch followed by water hyacinth (8.06 t/ha), while the lowest tuber yield was observed in no mulch (3.99 t/ha).
