    Soil Management and the Food Supply

    The effects of variations in the climate on the food supply are related almost entirely to variations in the temperature regime and in the rainfall. The appropriate management techniques, by adjusting the natu...

    Effects of copper deficiency on root nodules of subterranean clover

    Effects of copper deficiency on the development of subterranean clover root nodules were studied. These included a depression of the bacteroid content, an accumulation of starch in the invaded cells and a redu...

    The distribution of cobalt inT. subterraneum

    The distribution of cobalt in plants ofT. subterraneum grown on different levels of supply of cobalt and nitrate nitrogen has been measured, and the nodules and to a lesser extent the roots have been found to acc...

    Studies in the nutrition of the forage legumes

    The effect has been studied of varying levels of copper supply on the copper, iron and manganese contents of plants ofT. subterraneum in which the growth rate had been altered by variation in nitrate supply and l...

    Studies on the nutrition of the forage legumes

    Cobalt has been shown to have a beneficial effect on the growth ofT. subterraneum, whether the plants are nodulated or not, and which is largely independent of the effectiveness of the rhizobial symbiont used.

    Studies on the nutrition of forage legumes

    The numbers of nodules develo** on the roots ofT. subterraneum increased with increase in the supply of nitrate nitrogen in the nutrient up to 1000 µM per litre. When the copper is supplied at 0.01 µM per litre...

    Copper and Cobalt in Nitrogen Fixation

    THE hæmoglobin found in the nodules of leguminous plants, first demonstrated by Kubo, has been since shown to vary in quantity with the condition of the nodules, and both Virtanen et al. 1 and Jordan and Garrard2

    An evaluation of the maximum radius of the rosette as a growth index for subterranean clover

    The maximum radius of the rosette, defined as the distance from the centre shoot to the base of the leaf furthest from it, is highly correlated with yield of dry matter (r=0.98 to 0.93) over the earlier vegetativ...
