“…On acid flooded soils, even rice may suffer from Fe toxicity (DeDatta et al 1990). Graven et al (1965) reported that the Mn concentration increased in alfalfa shoots by soil flooding and that the Mn concentration reached a toxic level. Also Drew (1988) found that water logging often induces an increase of Mn and Fe in shoots of wheat and barley.…”

The aim of our experiments was to investigate whether nutrient deficiency or toxicity is the cause for growth inhibition of wheat and barley in waterlogged soils. Experiments using two soils (top and subsoil) differing largely in various characteristics revealed a growth inhibition of wheat and barley in the case of subsoil due to water logging, without Fe or Mn toxicity. Water culture experiments with anaerobic (N 2 ) and aerobic aeration confirmed that oxygen deficiency did not induce nutrient toxicity (Fe, Mn) but caused sub-optimum nutrient supply (N, P, K, Mn, Cu, Zn) of wheat and barley plants. In a split-root water culture experiment with barley, cultivating half of the root system in varying combinations of aerobic/anaerobic and with/without K supply, it was shown that sufficient K uptake occurred only when K and oxygen were applied in the same root compartment. We suggest that due to O 2 deficiency in the root medium, synthesis of ATP may be inhibited leading thus to a decrease in nutrient uptake. Nutrient deficiency rather than toxicity appears to be the major cause for the poor plant growth in waterlogged soils.

“…In flooded soils the reduced, divalent forms of iron and manganese occur, which are more soluble and therefore available to plants (Gotoh & Patrick, 1972, 1974. Toxicity of iron (Martin, 1968;Jones & Etherington, 1970;Wheeler, Al-Farraj & Cook, 1985;Etherington & Thomas, 1986) and manganese (Graven, Attoe & Smith, 1965;Jones, 1972;Singer & Havill, 1985;Etherington & Thomas, 1986) may limit growth and distribution of certain species in soils prone to waterlogging.…”

THE EFFECT OF MANGANESE ON ROOT EXTENSION OF GEUM RIVALE L., G. URBANUM L. AND THEIR HYBRIDS

SUMMARYRoot elongation of Geum rivale and G. urbanum grown in nutrient solution decreased as manganese concentration was increased above 25 mg dm"^, especially in G. urbanum. Prior exposure of roots to 25 mg Mn dm~^ increased their capacity for subsequent elongation in manganese solutions, the effect of such pretreatment being most pronounced in G. rivale. G. rivale was significantly more tolerant of 50 mg Mn dm"^ than G. urbanum. Efflux of potassium from root segments, used as a measure of niembrane permeability, was significantly higher in G. urbanum than in G. rivale at this concentration. Tolerance of 50 mg Mn dm~^ by progeny of hybrid individuals was generally related to morphological intermediacy, although there were some noticeable exceptions. Manganese tolerance of hybrids could not be consistently related to their known tolerance of waterlogging.

SummaryIn order to study the reasons for poor peanut (Arachis hypogaea L.) performance on an Avalon medium sandy loam, a three year field study was undertaken to investigate the effects of lime and gypsum applications on growth, yield and quality. Rates of up to 2,400kg agricultural lime/ha/annum significantly increased soil pH (1 N KCI) and exch. Ca and decreased levels ofexch. A1 and AI saturation in the soil ((~150mm). The effect of the same rates of gypsum was much less marked, only exch. Ca increasing and A1 saturation decreasing to any substantial extent. In the absence of lime (i.e. even where gypsum was applied), nodulation was poor and the plants developed a general chlorosis c. 90 days after planting. Liming markedly improved nodulation whereas annual applications of gypsum had the opposite effect. Liming significantly increased the hay, pod and kernel yields by up to 73, 105 and 117%, respectively. On average, gypsum applications had no significant effects. Liming increased shelling percentage, the percentage mature pods, 100-kernel mass and protein concentration in the kernel, and decreased the incidence of pops and kernels with black plumule. Applications of gypsum had little effect on quality except for a decreased incidence of black plumule. It appeared that the improved crop performance with liming resulted from a reduction in A1 toxicity which improved nodulation. Calcium deficiency did not appear to be a major cause of poor peanut growth and quality in the unameliorated soil.
