Abstract/ Executive Summary:

Seeds of 15 lines/cultivars of maize were subjected to salinity stress during germination and seedling growth using different concentrations of NaCl solution. Germination percentage and vigour index decreased with the increase in NaCl solution. On the basis of germination percentage (G%), seedling growth and vigour indices, eight lines/cultivars were selected and grown in the coastal saline areas of Noakhali and Potuakhali to evaluate their performance as fodder in those areas. In Potuakhali, out of these eight var./lines, the maximum fodder yield was observed in pacific 11 which is closely followed by pacific 60, BHM-4 and khoibhutta, though there is no significance difference of fodder yield (t/ha) observed among the cultivars/lines. The fodder yield ranged between 12 to 18 t/ha in Kuakata. But in Noakhali due to higher salinity, the fodder yield was 2 to 12 t/ha. In both the areas, khoibhutta gave best results in respect of fodder yield (24.52 and 20.08 t/ha) which is closely followed by BHM-4 (27.54 t/ha and 18.40 t/ha). This result was in keeping with that obtained under laboratory condition

Program Area: Crop-Soil-Water Management

Commodity: Fodder

Objectives:

To find out suitable maize var. / lines as fodder crop for cultivation in the saline areas of Bangladesh.

Methodology:

Fifteen different cv./lines of maize were tested against varying salinity level under laboratory condition. Salinity levels used were 0, 4 dS-m, 8 dS-m, 12 dS-m and 16 dS-m. Germination was carried out according to ISTA rule, 1985. To findout seedling growth, plants were grown in Hoagland nutrient solution with varying salinity level (0.4 dS-m, 4 dS-m, 8 dS-m, 12 dS-m and 16 dS-m ). On the basis of seedling growth and vigour index, 6 lines/cultivars along with pacific-11 and pacific 60 are also grown in coastal areas (Noakhali and Potuakhali) to evaluate their performance as fodder. The unit plot size was 4 m x 3 m with three replications. Fertilizer doses were given according to standard recommended practices. Line to line distance was 40 cm and plant to plant distance was 20 cm. The crop was sown on 15th December’06 in Kuakata, Potuakhali and 11th December’06 in Hazigong, Noakhali. Plants were harvested at 40 DAE, 60 DAE and 80 DAE to measure fodder yield. Vigour was measured by multiplying germination percentage with seedling length.

Achievement/Findings:

Of the six varieties which were selected from the laboratory test two varieties , Khoibhutta and BHM-4 could be recommended for cultivation in the coastal aeras of Noakhali and Potuakhali.The fodder yield in Potuakhali was conclusively higher compared to that in Noakhali. This is possibly due to higher salinity in Noakhali.
