Abstract/ Executive Summary:

Yield of Iratom-24 was higher than BRRIdhan-26 and it was mainly due to grain weight. Transplanted crop produced more yield than broadcasted one and spacing 15 cm x 10 cm produced the maximum grain irrespective of cultural practices. Again seed rate 80 was found to be optimum. The interaction data revealed that variety Iratom-24 with 15 cm x 10 cm produced the highest yield (3.35 t ha^-1) while BRRIdhan-26 with the same spacing produced (3.01 t ha^-1). Iratom-24 required more days to mature either transplanted or seed sown. Again duration of direct seeding of each variety required less days than transplanting.

Start Date: 17-04-2004

End Date: 28-08-2004

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To assess performance of rice variety Iratom-24 as transplanted aus

Methodology:

A experiment was conducted to assess performance of rice variety Iratom-24 as transplanted aus crop comparing it with BRRI recommended aus variety BRRIdhan-26. The experiment involved two varieties and six cultural practices such as transplanting with three planting spacing viz., 20 cm x15 cm (SP1), 15 cm x 10 cm (SP2) and 15 cm x 10 cm (SP3) and seed broadcasting with three seed rate viz., 80 kg ha^-1 (SR1), 100 ha^-1 (SR2) and 60 ha^-1 (SR3). The unit plot size was 6 m x 6m. Seeds with the treatment rate were sown on April17, 2004 and seedlings transplanted with the above spacing on May 27, 2004. The design used RCBD with three replications. Data were collected from 25 hills of transplanted crop and 1m² of broadcast crop and these were converted then per unit area and statistical analyses were done.

Achievement/Findings:

BINA released rice variety Iratom-24 with the check variety BRRIdhan-26 was evaluated in Aus season with six cultural practices such as transplanting with three planting spacing viz., 20 cm x15 cm, 15 cm x 10 cm and 15 cm x 10 cm and seed broadcasting with three seed rates viz., 80,100 and 60 kg ha^-1at Magura. The grain yield of Iratom-24 was higher than BRRIdhan-26 and transplanted crop produced yield than broadcasted one and spacing 15 cm x 10 cm produced the maximum yield. The variety Iratom-24 with 15 cm x 10 cm produced the highest yield (3.35 t ha^-1) while BRRIdhan-26 with the same spacing produced 3.01 t ha^-1.
