Three different sources of seed viz. S 1 = BADC seed, S 2 = BARI seed and S 3 = Farmers seed were used on experiment following Randomized Block Design with three replications. Maximum plant height (93.2 cm at harvest), number of tiller (4.9/m 2 at harvest), dry weight (74.2 g at harvest), spike length (17.5 cm), number of grains (40.5/spike), filled grains (39.6/spike), 1000-grains weight (42.3 g), grain yield (3.5 t/ha), straw yield (5.2 t/ha) and biological yield (8.7 t/ha) was found from S 2 which was statistically identical with S 1 whereas minimum from S 3 . The seed sources can be ranked from best to worst as BADC seed > BARI seed > Farmers seed. Farmer’s seeds were poor in the view of yield. Keywords: Seed sources, wheat, growth and yield INTRODUCTION Wheat (Triticum aestivum L.) is the most important cereal crop in the world as well as in Bangladesh. In Bangladesh, annual production of wheat about 737,000 metric tons (BBS, 2008). Though wheat is an important cereal crop in Bangladesh, the average yield is very low compared to that of advanced countries. There are many factors responsible for low yield, of which poor quality of wheat seed that reduces its yield if we not replace the diseased, poor quality, low vigor seed by good one. Availability of high quality healthy seeds is the crying need of the day in all segments of agriculture to ensure sustainable good crops. It also necessary to aware farmers about the consequences of the crop losses with low quality seed. For obtaining desired harvest, effectiveness of other inputs such as fertilizer, irrigation, pest control measure etc, depend largely on the quality of seeds (Rashid and Fakir, 2000). Seed requirement of wheat during 2006-07 in Bangladesh was 78.00 thousand metric tons of which wheat only 12415 metric tons was distributed by BADC (BADC, 2007). Use of good seeds can contribute to increase the yield remaining all other factors of production as constant. Improved quality seed supply in Bangladesh constitutes only about 390 tons which is about 33% of the total requirement and rest 67% seed are met by farmers and local seed traders (Vossen, 1994). This idea which is the source and place for hybrid seed production could have an effect on the next yield. In recent years, it has been proposed in scientific forums that in spite of the need for more investigation, unfortunately there are not enough sources in this case. Usually the farmers or other seed producers don’t provide appropriate measure to attain a good standard of seed quality. Considering the above fact, the study was conducted to judge the effect of seed source on growth and yield of wheat. MATERIALS AND METHODS An experiment was conducted at Agronomy field, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from November, 2011 to March 2012 to study the response of different seed sources on production of BARI Gom-24. Three different sources of seed viz. S 1 = BADC seed, S 2 = BARI seed and S 3 = Farmers seed were used on experiment following Randomized Block Design with three replications. Plot to plot distance was 4m × 2.5m whereas 0.5m and 1.0 m was the block to block distances. Seeds of wheat variety BARI GOM-24 (Prodip) for
