Abstract Leptochloa fusca (L.) Kunth (kallar grass) has previously been found to exhibit high
rates of nitrogen fixation. A series of experiments to determine the level of biological nitrogen …

Wheat is staple food crop of many countries including Pakistan. It has a large number of
cultivars and genotypes. All genotypes have different tissue culture response that includes …

Diazotrophs, especially of genus Azospirillum were readily isolated from roots of many
plants using semi-solid nitrogen free malate medium (NFM). These isolates formed fine …

Summary Leptochloa fusca (L.) Kunth (kallar grass) has previously been found to exhibit
high rates of nitrogen fixation. A series of experiments to determine the level of biological …

By the year 2050, world population is expected to double from its current level of more than
5 billion. It is reasonable that the demand of fixed nitrogen for crop production is also …

An ecological survey was made to measure the N 2-fixing activity in the rhizosphere of a salt-
tolerant grass, Leptochloa fusca (L.) Kunth. Samples were obtained every month at two sites …

[en] Present investigations were made by using sup/15/N isotope dilution technique to
quantitatively estimate BNF in Kallar grass when grown under controlled conditions in …

Experiments to determine the contribution of biological nitrogen fixation associated with
roots of Kallar grass have been carried out both in pot and field using 15 N isotopic dilution …

Two experiments have been conducted, one in semi-solid Hoagland nutrient medium and
the other in shallow pots containing saline soil. N 2-fixing bacteria belonging to Azospirillum …

Seven rhizobial strains were isolated from Sesbania aculeata and three from Sesbania
grandifolia from three different soil types. These strains were characterized for their …
