Abstract
Different rice modern varieties MV may differ in their nutrient concentration nutrient uptake and absorbed nutrients for grain production. These nutritional problems are not well addressed particularly in Bangladesh where 41 of 10 million hectare rice lands are covered with MV rice. This investigation was made in 1996 dry season under irrigated conditions on an Aeric Haplaquept soil at the Bangladesh Rice Research Institute Farm with five popularly grown MV rices-Purbachi BR1 BR3 BR14 and BR29. Straw and grain yields of the five rice varieties ranged between 3.90 to 4.66 adn 3.91 to 5.07 t haE-1 respectively. The highest straw yield was found in Purbachi while BR29 produced the highest grain yield. The lowest straw and grain yield was obtained by BR3. However there was no significant difference in straw and grain yields among the tested varieties p more than 0.05. The tested varieties showed significant differences p less than 0.05 or p less than 0.01 in content uptake and internal efficiencies of some major nutrients. Straw N P Ca and Mg and grain P Ca and S concentration differed significantly among the tested varieties while there was no difference in straw and grain K content. There was noticeable difference among the MV rices in total uptake of K Ca Mg and S but not of N and P although P uptake by grain was different among the varieties. Utilization of absorbed nutrient to produce grain internal efficiency was different in tested varieties for P Ca Mg and S but not for N and K. BR29 proved to be the best P and Mg efficient variety while BR14 was the highest Ca and S efficient. Purbachi and BR1 the two oldest MV rice in Bangladesh were the least S and P efficient respectively.
