Sour and sweet orange seedlings grown in 3-gallon pots in the greenhouse made approximately 50 to 175 per cent more growth in noncitrus soil, that is, in soil from areas which had never been cropped to citrus, than in old citrus soil from adjacent areas which had supported citrus trees 40 to 70 years. Seedlings in old citrus soil did not respond to applications of P,K,Mg, Cu,B, Zn, or Mn. Soil fummigation prior to planting usually controlled root rotting and the citrus root nematode (Tylenchulus semipenetrans Cobb) and markedly stimulated growth of sour and sweet orange seedlings in old citrus soil. In most noncitrus soils growth was only slightly increased or decreased by fumigation. Noncitrus soils taken from areas under or near pepper trees produced poor growth of citrus seedlings, but fumigation of these soils prior to ... |
