| Summary: | The objectives of this research are : (1) to fmd out a type of turi (Sesbania grandiflora) which has a potency as nitrogen source on marginal land, (2) the method of developing turi legin, (3) the development of organic fertilizer from turi biomass which can be used to improve nitrogen content on marginal land.
Three experiments had been carried out, i.e. :
( 1) analyses study of turi potency as nitrogen source on marginal land;
(2) analyses study ofturi roots development to become turi legin;
(3) experimental work, using explanted land and organic fertilizer of turi
biomass to increase soil fertility (with com as indicator plant). A complete randomized factor real design involving two factors, three replies was set up. The result of experiment showed that turi putih was more populated than turi merah. Nodul of turi merah was 37.24 while turi putih 62.87. Sizes of 3 em crushed leaves and 1 em cutted shoots enhanced decompotition process. Nitrogen content of 3 em cutted leaves of turi putih was higher thand other treatments. Turi legin could be prepared from rhizobium isolat both from nodul turi putih and turi merah. |
