Abstract/ Executive Summary:

Result of Rajshahi showed that the highest mean grain yield (4.13 t ha^-1) was obtained in August 15 transplanting. Varieties showed significant effect on the grain yield. Highest grain yield (4.46 t ha^-1) was produced by Binadhan-7 and second highest yield (3.78 t ha^-1) by Nerica-10. Lowest yield (3.67 t ha^-1) was obtained by Nerica-1. Interaction between variety and transplanting time did not showed significant effect on yield. Binadhan-7 produced highest yield in both transplanting time (4.63 t ha^-1 and 4.30 t ha^-1). On the other hand, result of Magura revealed that transplanting on August 15 and August 25 produced statistically similar grain yield (4.92 and 4.91 t ha^-1) and August 05 transplanting produced lowest (4.59 t ha^-1) although they are not significant. Varieties showed significant effect on yield. Highest mean grain yield (5.15 t ha^-1) was obtained by Binadhan-7 followed by Nerica-10 (4.83 t ha^-1). Interaction between transplanting date and variety did not show any significant effect on yield, Binadhan-7 performed better in respect of yield in all the three transplanting dates. Nerica-10 performed better in August 15 and August 25 transplanting dates.

Keywords: Transplanting date, Yield and Nerica rice

Location: Farmer’s field of Godagari, Rajshahi and Sub-station, Magura

Start Date: 05-07-2012

End Date: 10-11-2012

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

The objective was to evaluate the yield performances of these varieties in different transplanting time

Methodology:

Two drought tolerant rice varieties were evaluated compared to one check varieties at the farmer’s field of Godagari, Rajshahi and Magura during aman season, 2012-13. The varieties were Nerica-1, Nerica-10 and Binadhan-7 as check. The three transplanting time were August 05, August 15 and August 25 in Magura and two transplanting time (August 15 and August 25) in Rajshahi. The experiment was laid out in a RCB design with three replications. Data on yield and yield components were recorded at harvest and were statistically analyzed following the design used for the experiment and the means were compared with LSD.
