Abstract/ Executive Summary:

Fifteen genotypes of Triticale were tested in two salt affected locations namely Satkhira and Noakhali during 2006-07. At Satkhira, genotype E₆ and E₁₄ produced significantly the highest grain yield (2.00 t/ha) from December 28 sowing date. While the highest fodder yield was obtained from line E₇ (6.94 t/ha). However, E₆ produced good amount of green fodder (5.62 t/ha) as well as the highest grain yield (2.00 t/ha), so, genotype E₆ could be used for dual purposes. On the other hand, at Noakhali genotype E₅ gave the highest grain yield (2.48 t/ha) which was statistically similar to E₁₁. However, E₁₁ produced the highest amount of green fodder (9.88 t/ha). Hence, E₁₁ could be used for the dual purposes. In both locations it was observed that soil salinity above 6-7 dS/m hampered the growth and development of the crop. To reduce the toxic effects of salinity on seeds, irrigation would be advisable just after sowing. Crop failure was observed when soil salinity was above 10 dS/m.

Keywords: Triticale genotypes, Salinity, Grain, Fodder.

Location: Banerpota Farm of Bangadesh Agricultural Research Institute (BARI), Satkhira and Noakhali

Start Date: 00-01-2006

End Date: 00-12-2007

Program Area: Risk Management in Agriculture

Commodity: Fodder

Objectives:

To produce quality green fodder and considerable quantity of grain through re-growth after cutting green fodder.

Methodology:

The trial was conducted at Banerpota Farm of Bangadesh Agricultural Research Institute (BARI), Satkhira and Farming Systems Research and Development (FSRD) site of BARI, Hajirhat, Noakhali during the Rabi season of 2006-2007 with fifteen triticale genotypes namely E₁, E₂, E₃, E₄, E₅, E₆, E₇, E₈, E₉, E₁₀, E₁₁, E₁₂, E₁₃, E₁₄, and E₁₅ following RCB design with two replications. The unit plot size was 5mX1m. At Satkhira the crop was sown on 28 December 2006, while at Noakhali sowing was done on 4 December, 2006 as line sowing. Line to line distance was 20cm. Fertilizers were applied at the rate of 126-26-38-20 kg NPKS ha-1 as urea, TSP, MP and gypsum, respectively. All the amount of TSP, MP and Gypsum were applied as basal while 55 % of urea was applied as basal and the rest 45 % as top dress after cutting of green fodder at 45 days after sowing (DAS). Three irrigations were given during the crop growing period. Cutting of green fodder was done on 45^th DAS at Satkhira and on 42^nd DAS at Noakhali. The land was kept weed free. Data on grain yield, yield attributes and green fodder yield were collected and analyzed statistically by using MSTAT program.

Achievement/Findings:

Triticale could be an alternative option for brining fallow saline areas under cropping during rabi season. It was observed that triticale is a bit more salt tolerant in comparison to other competitive crops. At Satkhira, E₁₄ and E₆ triticale genotypes performed better, moreover, E₆ could be used for both green fodder and grain production. Whereas at Noakhali, E₅ and E₁₁ gave higher grain yield. E₁₁ also produced the highest green fodder yield; hence this genotype could be used for dual purpose. Therefore, triticale could be grown in Fallow-T. Aman -Fallow cropping pattern in the vast fallow land of the saline belt during the rabi season.
