The efficacy of foliar applied manganese (Mn) in preventing Mn deficiency in safflower (Carthamus tinctorius L. cv. Gila) was assessed in a black clay soil in the South-East of South Australia. The application of Mn significantly increased seed yield? from 1040 to 1450 kg/ha, through an increase in the number of seeds per plant. Maximum yields were attained by a foliar application of 500 g/ha of Mn. In the youngest open leaf the critical nutrient range (CNR) for Mn was 9-13 8g/g, while for the upper primary stem a CNR of 2-3 8g/g was determined. The CNR for Mn in the seed was found to be 5-6 8g/g.

The efficacy of the application of manganese, either applied to soil or as foliar sprays at three stages of flower development, in preventing the expression of manganese deficiency (ruptured seed coats ('split seed'); delayed maturity ('regreening'); and poor grain yield) in two cultivars of Lupinus angustifolius (cvv. Marri and Illyarrie) was assessed on sandy soils of the upper South East and Eyre Peninsula regions of South Australia. Six experiments were conducted during 1979 and 1980. A single foliar application of manganese (1.7 kg Mn/ha, in 200 litre water) when the upper-lateral shoots were in mid-flower, prevented the onset of the disorder. Applications of manganese to the soil at sowing at rates of up to 11.1 kg Mn/ha were usually less effective. The appearance of 'split-seed' symptoms in mature grain was a more sensitive indicator of manganese deficiency than was grain yield response to manganese fertilization. The degree to which these symptoms appeared increased markedly when the manganese concentration in intact seed became less than 8-10 �g/g dry seed, an observation which is consistent with other studies.

Pot Experiments

In pot experiments with a polder soil low in reducible Mn (extractant: 1N NH4OAc + 0.2% hydroquinone at pH 7), 50 kg/ha Mn applied as MnO (55 or 63.5% Mn) or MnSO4 (32.5% Mn) were as effective for preventing Mn deficiency in oats as spraying with MnSO4 or Mn-Rayplex (a polyflavonoid); reducible Mn in the soil increased to 50-60 ppm. With a more recent polder soil where Mn deficiency was not closely related to reducible Mn, but to C/N ratio, applying up to 176 kg/ha Mn did not completely control Mn deficiency.

SUMMARYField experiments in 1987 and 1988 on peaty-loam, Mn-deficient soils of the Adventurers series in Cambridgeshire, UK, tested the response of sugarbeet to three forms of manganese fertilizer supplied as foliar sprays. The influence of a wetter and an adjuvant on manganese absorption and growth was also investigated.Cutonic and chelated forms of Mn, when applied at standard rates, were inefficient at increasing Mn concentrations in plants and alleviating deficiency symptoms during early summer. Mn concentrations in foliage increased rapidly after spraying with manganese sulphate, and most of the deficiency symptoms disappeared. These benefits were usually enhanced when manganese sulphate sprays were used with an adjuvant.Averaged over both years, yield without Mn was 8·83 t sugar/ha; the largest yield, 9·56 t/ha, was obtained with manganese sulphate plus adjuvant. Smaller benefits were obtained with the other forms of Mn. The adjuvant, when used with chelated Mn, appeared to depress sugar yields in both years. The likelihood of reducing the number of sprays required to control Mn deficiency on Fen soils was improved by using an adjuvant with manganous sulphate sprays.

Wilting Point

The effects of limiting water potentials on the germination characteristics of 12 grasses were studied. Germination proper was prevented in all species at water potentials well short of wilting point and different species had their germination prevented at different potentials. Generally the native grasses required wetter conditions to germinate than the exotic grasses, although there were some exceptions. A partial germination condition, caused by limited water availability, occurred to differing degrees amongst the species. Some species retained their viability when desiccated in the partially germinated condition, but other species lost their viability. The partial germination phenomenon appears important to the germination ecology of some species but not to others.

Iron Sulphate

A severe iron deficiency in peas grown on grey to black clay loam soil overlying limestone (rendzina) was successfully ameliorated by foliar application of ferrous sulphate. Two applications, three weeks apart, increased the fresh weight of peas harvested by more than 100 per cent (P < 0.001). The two sprays also increased the numbers of pods, dry weight of the pods, fresh weight per pea and maturity of the peas (all P < 0.001), and herbage yield (P < 0.01). One application of iron sulphate was insufficient to arrest completely the symptoms of iron deficiency. The peas did not show vegetative or marsh spot symptoms of manganese deficiency, and there were no significant changes in measurements to manganese sprays.
