(2020-06-05)Microscopic examination of stallion spermatozoal morphology provides a useful criterion for assessing the quality of semen and reproductive capabilities of a stallion. In previous investigations, personnel in our laboratory ...
-
(Texas A&M University. Libraries, 1978)Chemical fixation of dinitrogen has been performed under mild conditions in homogeneous and heterogeneous systems. In heterogeneous system electron donor-acceptor complexes of iron phthalocyanine, ruthenium phthalocyanine, ...
-
(Texas A&M University. Libraries, 1980)The most generally limiting nutrient to growth of forage grasses is fixed nitrogen in the form of No3- or NH4+. Dinitrogen fixation by bacteria associated with forage grass roots in a system which would provide plants with ...
-
The effect of nitrogen fixation on the protein quality of southernpeas, Vigna unguiculata (Cowpeas) (Texas A&M University. Libraries, 1981)The effects of nitrogen fixation on protein quality of southernpeas were studied. Differences in levels of nitrogen fixation were induced through variety selection and inoculation with Rhizobium bacteria. Growing seasons ...
-
(Texas A&M University. Libraries, 1987)Nitrogen-fixing bacteria in the rhizosphere of cereal grasses may reduce the fertilizer nitrogen requirements of grass crops by providing them with fixed nitrogen. This study evaluated the effects of oxygen partial pressure, ...
-
(Texas A&M University. Libraries, 1980)Cowpea, because of its ability to fix atmospheric nitrogen, coupled with its drought tolerance and ease of digestion, has become an important proteinaceous crop throughout the semi-arid regions of the world. Little research ...
-
(Texas A&M University. Libraries, 1983)Drought resistance and biological nitrogen fixation (BNF) potential of 437 diverse cowpea genotypes were determined. Plants were grown in irrigated and dryland plots in 1979 and 1980 near Lubbock, Texas. Drought resistance ...
-
(Texas A&M University. Libraries, 1985)Field and greenhouse studies were conducted at College Station, Texas to investigate the interrelationships between biological N2 fixation and seed yield in cowpea [Vigna unguiculata (L.) Walp.]. Seed yield of inoculated ...
-
(Texas A&M University. Libraries, 1980)Two low molecular weight peptides, each with a molecular weight of about 5.000, were isolated from soybean nodules. The levels of these peptides were positively correlated with the level of nitrogenase activity. These ...
-
(Texas A&M University. Libraries, 1985)Arrowleaf clover (Trifolium vesiculosum Savi) and ryegrass (Lolium multiflorum Lam.) are commonly grown together but the fertilizer N needs of these plants when grown in mixture are not well understood. Two greenhouse and ...
