“…Fukuju Nigo) seedlings were germinated in well-washed sand under greenhouse conditions in May. Plants in the 3rdleaf stage were transferred into an aerated complete nutrient solution containing 50 ppm nitrate-N, as described previously (10). When plants reached the 6th-leaf stage, they were transferred to the various treatment media.…”

Simultaneous supply of nitrate and high concentrations of ammonium prevented ammonium injury of tomato plants and resulted in much better growth than when tomato plants were grown on ammonium as the sole source of N. Potassium concentrations in shoots were not affected by the differences in N sources, but K accumulation was decreased in plants supplied with ammonium alone. Plants grown on ammonium with or without nitrate took up less Ca and Mg and had lower concentrations of Ca and Mg in the shoots than did plants which received only nitrate. Contents of organic acids decreased more rapidly in the shoots of plants supplied with ammonium alone than in those of plants supplied with ammonium plus nitrate. Supply of ammonium and nitrate together alleviated the rapid decrease in organic acid concentrations in the shoots of plants grown on ammonium alone.

Effects of isobutylidene diurea (lBDU) , osmocote, ammonium sulphate «NH4) 2S04) , and urea fertilisers in the presence or absence of a nitrification inhibitor, 2-chloro-6-(trichloromethyl) -pyridinie ('N-serve') on the dry matter yield and nitrogen uptake of Callistephus chinensis (L.) Nees (aster) in three New Zealand commercial nursery potting media were determined. The three media were: peat-sand (P-S), peat-sand-sawdust (P-S-saw), and peatsand-soil (P-S-soil). Dipton peat was used in the main experiment and Mataura peat in the split-application experiment. In the main experiment, generally, in P-S and P-S-saw, IBDU, osmocote, osmocote and N-serve, (NH4)2S04, and urea produced significantly higher yields than did IBDU and N-serve, urea and N-serve, and (NH4)2S04 and N-serve, which contained higher concentrations of nitrogen. The reduced growth of plants was probably because of ammonium toxicity. All fertiliser treatments, including the N-serve treatment, gave similar results in the soil medium. This was attributed to high amounts of NOs-N present, reducing the toxic effect of high NRI-N regimes. Results also showed that asters could be grown equally well in all three media, provided adequate water and nutrients were present. There were, however, indications that the P-S-saw medium encouraged better root growth particularly when the fertilisers were applied as split dressings. The split application of (NH4)2S04 and also that of urea reduced growth substantially in the P-S-saw medium by rapid immobilisation of applied N. Root growth in the first 49 days was greater in the Mataura peat-based media than in the Dipton peat-based media.
