Fertility Studies on Brassicas Grown in Acid Soils

Rhizosheaths on wheat grown in acid soils: phosphorus acquisition efficiency and genetic control

Rhizosheaths comprise soil bound to roots, and in wheat (Triticum aestivum L.) rhizosheath size correlates with root hair length. The aims of this study were to determine the effect that a large rhizosheath has on the phosphorus (P) acquisition by wheat and to investigate the genetic control of rhizosheath size in wheat grown on acid soil.Near-isogenic wheat lines differing in rhizosheath size ...

Ascorbic acid in some oleiferous brassicas cultivated in Pakistan.

Certain forms of oleiferous brassicas (brown-seeded sarson, Japan rapes and toria) are grown in Pakistan as oilseeds and fodder crops, and some varieties of these have been introduced recently as new crops in consequence of work done at the Agricultural Research Institute, Lyallpur. In the young stage the plants are eaten as vegetables; the non-fibrous stem known as gandal mixed with the young ...

Zinc Fertilization of Rice Grown on Clay Soils in Arkansas

Zinc (Zn) fertilizer is not currently recommended for rice grown on clay or clay loam soils in Arkansas. In 2003, eight field sites were established to evaluate the response of rice grown on clay soils to Zn fertilization. Shortly before or after seeding, granular Zn fertilizer was applied to the soil surface at rates of 0, 5, 10, and 20 lb Zn/acre. Tissue Zn concentration 10 to 14 days after f...

Cciv. Studies on Yeast Grown

IN the previous communication [Pett, 1935, 3] the observation was reported that yeast could be grown in media containing cyanide. The resulting yeast was found to have a high fermentative capacity, and a respiration largely insensitive to cyanide. It contained several times the normal content of flavin, in the form of flavoprotein. The present communication gives a comparison of cyanide-yeast w...
