Abstract/ Executive Summary:

An experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during rabi season of 2012-2013 to evaluate planting method and seed priming effect on the yield of hybrid maize in saline areas. There were six treatment combinations viz. T1: No Priming + normal sowing, T2: No Priming + ridge sowing, T3: Seed priming with 1% NaCI Solution + normal sowing, T4: Seed priming with 1% NaCI Solution + ridge sowing, T5: Seed Priming with water + normal sowing, T6: Seed Priming with water + ridge sowing. The highest grain yield (10.07 t/ha) was recorded in T4 treatment while the lowest in T1 treatment (7.91 t/ha). The lowest level of soil salinity was (3.25 ds/m) recorded at the sowing time and the highest level of salinity was (10.15 ds/m) recorded at the harvesting stage.

Start Date: 00-00-2012

End Date: 00-00-2013

Program Area: Crop-Soil-Water Management

Commodity: Maize

Objectives:

To evaluate seed priming and planting system on hybrid maize production in saline soil.

Methodology:

The experiment was conducted at Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during the rabi season of 2012-13. The variety was BARI Hybrid maize-7. There were six treatment combinations viz. T1: No Priming + normal sowing, T2: No Priming + ridge sowing , T3: Seed priming with 1% NaCI Solution + normal sowing, T4: Seed priming with 1% NaCI Solution + ridge sowing, T5: Seed Priming with water + normal sowing, T6: Seed Priming with water + ridge sowing were tested in a randomized complete block design with three replications. Seeds of different varieties were sown on 01 January, 2013 at Benarpota with a spacing of 75cm x 25cm. Unit plot size was 4.2m x 4m. The trial was fertilized with 250-55-110-40-5-1.5 kg/ha of N P K S Zn B (FRG/2005), respectively. One third N along with full amount of other fertilizers were applied as basal. Remaining N was top dressed in 2 equal splits at 40 and 70 DAS. Two irrigations were given following the urea top dressing. Earthing up was done when plants attained at three leaves stage. Three times weeding and necessary plant protection measures were taken. Data on different plant characters and yield were recorded and analyzed statistically using MSTAT-C program.

Achievement/Findings:

The highest grain yield (10.07 t/ha) was recorded in T4 treatment while the lowest in T1 treatment (7.91 t/ha). The lowest level of soil salinity was (3.25 ds/m) recorded at the sowing time and the highest level of salinity was (10.15 ds/m) recorded at the harvesting stage. In saline areas seeds of maize should be primed with 1% NaCl and planted in ridge bed to obtain higher grain yield.
