A systematic study was made of nutrient problems associated with regression in the productivity of sown pasture on an acid soil on the Southern Tableland, NSW. Soil deficiencies of calcium, magnesium, nitrogen, phosphorus, sulphur, potassium, molybdenum, boron and possibly zinc, were demonstrated, and the first report of copper deficiency on a highland soil is recorded. A pH effect was also involved. The remedial fertilizer treatments developed, increased pasture productivity to a level approaching average yields for Southern Tableland soils. The findings are also relevant to horticultural and forest production in the area, and could be useful in regeneration of native species on these soils in National Parks.

Yield and nutritive value of three summer annual forages, hybrid forage sorghum (Sorghum spp. hybrid cv. Zulu), bulrush millet (Pennisetum typhoides cv. Tamworth) and white panicum millet (Echinochloa crusgalli var. edulis) were determined in three experiments. Uninterrupted growth was measured every 2 weeks between 4 and 12 weeks after sowing, and leaf, stem and inflorescence components analysed for nitrogen, phosphorus, calcium, magnesium, sodium and potassium and dry matter digestibility by an in vitro technique. The value of 10-week-old herbage, from crops grown with 50 kg ha-1 N, was determined by grazing with 18 Jersey cows and by feeding chopped material to 12 cows indoors. White panicum was the lowest yielding forage (up to 6,360 kg ha-1 at 10 weeks) but contained the highest concentration of nitrogen, phosphorus, calcium and magnesium in both leaf and stem fractions at all stages of growth. After 10 weeks growth this feed contained a high proportion of seed and was eaten in arger quantities than zulu sorghum or bulrush millet. Cows grazing white panicum produced the highestr lmilk yields (6.5 and 7.1 kg cow-1 day-1 indoors and grazed) and milk from these cows contained a highe solids-not-fat and protein content than milk from cows fed bulrush millet or sorghum. Zulu sorghum was highest yielding (1 1,240 kg ha-1 at 12 weeks in experiment 1 and 81 50 kg ha-1 at 10 weeks in experiment 2). With advancing maturity stem content increased (>80 per cent from 8 weeks onwards) and the nitrogen content of both leaf and stem fractions rapidly declined to sub-optimum levels. Milk production of cows feeding on zulu sorghum was low, averaging 4.7 and 6.0 kg cow-1 day-1 for indoor and grazing experiments. Bulrush millet produced high forage yields with a higher leaf content than zulu sorghum and milk yields were higher. Butterfat content of milk from cows feeding on bulrush millet was lower than when cows were fed the other forages. It was concluded that these three forages are capable of providing a large bulk of feed but their feeding value at a semi-mature stage of growth is similar to perennial tropical pastures.

American sycamore (Platanus occidentalis L.) is a common native species in eastern North America and is planted widely as a landscape tree in other regions. During a survey of powdery mildew diseases in Washington State, the fungus Microsphaera platani Howe was found on American sycamore trees in Madison Park, Seattle. This report documents the presence of M. platani in Washington State and presents information on the fungus. Accepted for publication 30 July 2003. Published 18 August 2003.

Nitrogen, P, K, Ca, Mg and Na concentrations and accumulations in Willamette red raspberry (Rubus idaeus L.) plant parts were measured in a field study to identify a potential plant-analysis-based method for evaluating site-specific fertilizer requirements. Dry matter and macroelements accumulated steadily in new canes over the season, increased early to a stable amount in floricane laterals and ripe berries, increased and then decreased in leaves and remained stable in stems. Macroelement accumulation patterns were generally similar to dry matter accumulations. The amounts of N and K that accumulated in ripe berries were similar and about eight times greater than P, Ca and Mg. Macroelement concentrations of floricane stems, laterals and berries were more stable than in leaves, making them potentially more suitable than leaves for developing tissue analysis for fertilizer recommendations. Key words: Nitrogen, phosphorus, potassium, calcium, magnesium, sodium, Rubus idaeus

An experiment was conducted to determine the effect of different levels of black point infection caused by Bipolaris sorokiniana and other fungal pathogens on some quality characters of wheat grain. Wheat grains were graded on a 0-5 scale based on levels of black point infection. Quality characters of grain viz., protein, fat, dry matter, ash and mineral contents under different grades were determined following standard methods. The dry matter and ash contents of grain decreased while the contents of protein and fat increased with the increasing severity of black point infection. The observations on macro and micro nutrient contents of grain indicated that the amount of nitrogen, phosphorus, calcium, magnesium, sulphur, and boron increased, whereas the contents of potassium, iron, zinc, copper and sodium decreased with the increase of black point infection. However, the reductions in copper content of black point affected grains under different grades of infection were not significant as compared to apparently healthy grains.

Alfalfa samples at the hay stage of development were harvested by hand from 35 farms where bloat was a serious problem and from 38 farms where bloat did not occur even on lush legume pastures. The samples were analysed for nitrogen, phosphorus, potassium, sulphur, calcium, magnesium, and true protein. There were no differences in the mean contents of these constituents between bloating and non-bloating farms. There were wide ranges within both types of farm; true protein for example varied from 7.3 to 14.6% in alfalfa from bloating farms, with a similar range from 7.7 to 16.9% from non-bloating farms. Correlation coefficients revealed a significant association between nitrogen and phosphorus (.488) in alfalfa from non-bloating farms. There were significant associations between sulphur and nitrogen (.366) and between sulphur and protein (.707) in alfalfa from bloating farms. This correlation between sulphur and protein was the only coefficient that was significantly different from the corresponding correlation coefficient for non-bloating farms.

Eucalyptus Clone

Species of Scolytidae and Platypodidae were evaluated in a plantation using a clone of Eucalyptus grandis x Eucalyptus urophylla in the State of Minas Gerais, Brazil. Wood disks with galleries were taken from 15 eucalyptus trees between 0.5 and 1.5 m height. After collection, all trees attacked were burned. Woodborers obtained from these disks were identified as Premnobius cavipennis, Premnobius ambitiosus, Dryocoetoides cristatus (Coleoptera: Scolytidae) and Euplatypus parallelus (Coleoptera: Platypodidae). This is the first report of D. cristatus, a Brazilian native species, damaging eucalyptus, which shows its adaptation to this plant.
