The effect of nitrogen concentration and amount of liquid feed on tomatoes grown in peat substrates


, : The effect of nitrogen concentration and amount of liquid feed on tomatoes grown in peat substrates. Acta Horticulturae (26): 187-193

The effects were studied of 141, 278 or 556 p.p.m. N in the liquid feed applied daily or on alternate days on the yield, size, colour and chemical composition of tomato fruit of spring and autumn crops of cvs Ware Cross and Eurocross BB. In both crops high N tended to decrease yield by reducing fruit size, but the full feed resulted in smaller fruit only with the spring crop.

Three concentrations of K in the liquid feed, 2 lime sources and 3 cultivars were compared in a long-season crop of tomatoes grown in a peat substrate with 14 l/plant. Increasing the K concentration from 180-280 mg/l increased the yield but a furt...

The 150 p.p.m. N rate was sufficient for high yields...

The effects of N were less marked, but intermediate levels in the liqu...
