Microorganisms are important for agriculture in order to promote the<br> circulation of plant nutrients and reduce the need for chemical fertilizers. Today researchers are<br> able to repeatedly use them successfully in field experiments to increase growth and yields of<br> some crop and vegetables in different nations; however data on the effect of cyanobacteria on the<br> growth of rice, tomato and pepper seedlings is inadequate. The aim of this study was to isolate<br> and evaluate the effect of cyanobacteria on the growth of rice, tomato and pepper seedlings with<br> deferent cultivars. The study designs were randomized, purposeful laboratory based experiment.<br> Sediments sample used to isolate Bacillus and soil sample used to isolates Cyanobacteria were<br> collected randomly from Lake Tana and from Gondar Teacher Education Collage respectively.<br> The seeds of Peppers and Tomato were collected from Adet Agriculture Research Center and<br> Rice seeds from Woreta Rice Research Center. The seedling of pepper, rice and tomato were<br> prepared in University of Gondar, Biology department field experiment station. Pot experiments<br> in laboratory were conducted to evaluate the effect of Cyanobacteria and Bacillus on Rice,<br> Pepper and Tomatoes seedling. Five Bacillus and two Cyanobacteria species were isolated and<br> identified from Lake Tana and from Lake Tana and from Gondar Teacher Education Collage<br> respectively. All five Bacillus and tow Cyanobacterial isolates showed positive effects on the<br> growth of pepper, rice and tomato seedlings as compared to the control, however their<br> effectiveness varies from isolate to isolate and also from cultivar to cultivar. Among all<br> Cyanobacteria isolate (C1) was considered as having more plant growth promoting ability in all<br> cultivars of tomato Melkesalsa (70%, 70.4%), kochero (75%, 76%) and Miya (92.5%, 79%)<br> shoot length and root length respectively relative to other. In pepper plant cv. Endiam42 from all<br> isolates C1 provide more growth promotion with efficacy (80.73%,66. 72%) shoot length and<br> root length respectively and in cv. Markofana B4 was showed higher efficacacy(81.5%, 73.86%)<br> shoot length and root length respectively relative to other. In Rice cv. X-jigna and cv. Edget C2<br> showed higher growth promotion efficacy (37.93%, 50.53%) and (50.07%, 52.9%) respectively.<br> Thus, microorganisms could be considered as one of the possible biofertilizer that leads to<br> increase the health and vigor of seedlings.</p></subfield> </datafield> <datafield tag="773" ind1=" " ind2=" "> <subfield code="n">doi</subfield> <subfield code="i">isVersionOf</subfield> <subfield code="a">10.20372/nadre:5339</subfield> </datafield> <datafield tag="024" ind1=" " ind2=" "> <subfield code="a">10.20372/nadre:5340</subfield> <subfield code="2">doi</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="a">publication</subfield> <subfield code="b">thesis</subfield> </datafield> </record>
