The plants were grown in vessels composed of two parts: in the upper one, with the perforated bottom, was mixture of peat with brown coal or peat with scoria, and in the lower one - a nutrient solution to a height of 12 cm. The lowering of nitrogen fertillization (to 43%) and the increase in the molybdenum salt dose produced a positive difference in yield. A 3,7 g dose of fertilizer mixture per plant during the vegetation season has been found to be optimum. The detergent, when applied only once, improved the crop quality. When applied every fourth week, it caused a decrease in the number of racemes per plant grown on a slag~peat seedbed, whereas, on the lignitepeat seedbed all the detergent action was annulled.

In experiments with 5 vegetables and 5 decorative species – coal from both mines proved to be appropriate as the seedbed. Both types of coal stimulated root growth and maintained iron in soluble form. In general, better and earlier crops were obtained in hydroponic cultures than in pots filled either with soil or with coal watered with nutrient solution.

Abstract A description is provided for Ramularia alba. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Lathyrus odoratus, the sweet pea. DISEASE: White blight of sweet pea, also called white mould or Cladosporium blight. Leaf spots vary from yellow flecks to buff coloured dead areas, which may be circular or irregular in shape merging gradually into healthy leaf tissue. Leaf spots may merge together affecting most of the leaf and in such cases defoliation may result (30, 41). GEOGRAPHICAL DISTRIBUTION: Europe (Denmark, England, Sweden). North America (Canada: British Columbia, Ontario; USA: California, Massachusetts, New Jersey, New York, Pennsylvania, Texas). TRANSMISSION: By wind dispersal of air-borne conidia.

Ammonium saltpeter used in hydroponic nutrient solution instead of calcium saltpeter decreased the yield of tomatoes by 30%. A smaller (15,4%) decrease in yield was observed when ammonium saltpeter was used jointly with urea. The 50% reduction of light gave a considerable 60% drop in the yield. The levels of phosphorus and chlorophyll in leaves of tomatoes grown under the above conditions were considerably higher than in tomatoes cultivated in full light. All the tomato plant took up almost the same quantities of mineral salts.
