Nodules from mungbean crop raised for the fi rst time at Ram Dhan Singh (RDS) farm of Chaudhary Charan Singh (CCS) Haryana Agricultural University, Hisar were collected from 17 different locations. Twentyfi ve mungbean rhizobia were isolated and authenticated by plant infection test. DNA of all these rhizobia was extracted purifi ed and amplifi ed using enterobacterial repetitive intergenic consensus (ERIC) primers. All the mungbean rhizobial isolates were clustered into 4 groups at 65% of similarity and were further divided into 17 subclusters at 80% of similarity. All the 4 types of rhizobia were not present at any of the location and group 2 or 4 rhizobia were invariably present. Effi cacy of these rhizobia in terms of nodulation, nitrogen uptake and chlorophyll a fl uorescence was determined under pot culture conditions. Strain MB 307 showed maximum nitrogen uptake of 31.9 mg N plant -1 followed by strain MB 1205, MB 1206(2), MB 308, MB 1524 and strain MB 1521 was found to be the least effi cient in terms of N 2 fi xation. Nodule occupancy by different rhizobia ranged from 5.5 to 40.3%. Most of the strains belonging to the 2nd group which clustered maximum number of strains were comparatively better competitors and formed 19.5-40.3% of the nodules and were also effective. Isolate MB 307, the most effi cient strain, was found to have nodule occupancy of 31.5%. Such type of predominant, effi cient and better competitor strains should be selected for enhancing nodule competitiveness.
Bangladeshi farmers gain traditional agricultural knowledge and skills by hereditary. Such experience and historic knowledge are now inadequate to meet the food requirement of the huge population of the country. Thus modernization of the traditional system is very essential for the agriculture sector of Bangladesh. This article focuses on the innovations and developments. As such we have given focused on by ICT access in agricultural sector of Bangladesh. Bangladesh is a developing country. Agriculture, being one of the major driving forces is contributing maximum share to the GDP and the growing economy of the country. Almost 80% of the total workforce directly connected to agriculture (Kashem et al., 2010). Due to the rapid growth of population the food demand is increased. Though the agricultural sector is developing it does not achieve the optimum level due to lack of up to date knowledge and information. Usually the farmers counter difficulties in obtaining the proper information as they collect information from conventional and traditional sources like extension fellow farmers. From season to season there is high demand of up to date information for new cultivation processing techniques, pest and diseases control, marketing and consumer demand, crops transport etc (Malone et al., 2012).Timely and accurate information can assist farmers to protect from potential seasonal losses. Up to date knowledge can helps them to make optimum use of limited resources. As such the conventional method of cultivation is to be changed using modern digital ICT services.The Country has stepped into new era of digital world with a spectacular vision for making Digital Bangladesh. This vision would be saddled by e-agriculture involving multi disciplinary initiatives of agricultural information, agricultural development and entrepreneurship towards building a hunger free, efficient and resourceful Bangladesh.The history of ICT use in Bangladesh agriculture is not so rich. ICT taskforce program launched in 2003 by the ministry of agriculture perhaps would be the first initiative to set up on Agricultural Information system. Recently a dedicated division Agricultural Statistics and Information & Communication Technology (ASICT) has been established in BARI for providing the agricultural Information
