Effect of early sowing on the growth, yield and quality of sugar beet.

End of Project ReportExperiments have shown that yield of sugar is closely related to the amount of solar radiation intercepted by a sugar beet crop. Early sowing increases leaf area from May onwards when radiation is at its maximum and provides a basis for increasing yields. In the past, bolting has been an undesirable consequence of early sowing but some modern cultivars have good bolting resistance and can be sown early with a limited risk of bolting. This study, conducted from 1994 to 1998, compared the performance of two cultivars, Celt and Monofeb, at three sowing dates and three harvest dates. In replicated experiments, plant establishment, crop development, and root yield and quality were assessed. The effect of sowing date on solar radiation interception was studied. Effects of in-furrow pesticide application on pest numbers and plant damage were also measured. Plant establishment was influenced by sowing date with the early sowings generally giving lower plant numbers than the later ones. The cultivar Celt produced higher populations than Monofeb at all sowing dates. Early sowing increased the leaf area index (a measure of the ratio of leaf to land area) and consequently the amount of solar radiation intercepted. This was particularly so in June when solar radiation levels are highest. Early crop establishment provides the opportunity to exploit good weather conditions which may occur in April or May. Pest numbers generally were small at all the sites. Insecticide had a greater effect on pest numbers and plant damage than it had on plant establishment; the beneficial effects of pesticide were slightly more pronounced for the early and mid-season sowings than for later-sown beet. Seedling diseases were not a problem at any time of sowing. Poor emergence, where it occurred, was not associated with pre-emergence disease. Early to mid-March sowings produced significantly higher yields of roots and sugar than the early or late April sowings over the period of the experiment. Even in years when plant populations from the first sowings were much lower than subsequent sowings, yields tended to be at least equal to those of later sowings. Monofeb produced a slightly higher root yield than Celt, but because it had lower sugar contents there was no difference in sugar yields. Harvesting extended over the period from early October to mid-November and root growth and sugar production increased over that period irrespective of sowing date. Bolting was a problem in 1996 on the early-sown plots, particularly with the cultivar Celt.Teagasc acknowledges the support of Irish Sugar plc and Sugar Beet Levy Farmer Funds in the financing of this projec

Chemical composition and sensory acceptability of partially gelatinised pasta produced from blends of wheat, bambara nut and cassava flours

Pasta products were produced from partially gelatinized blends of wheat, cassava and bambaranut nut flours. The three flours from wheat, cassava and bambaranut nut were blended in the following ratios: 100% wheat flour, 64:10:26, 60:12:28, 56:14:30, 52:16:32 and 48:18:34 flour blends, representing samples A, B, C, D, E and F, respectively. 180 ml of water and 65 ml of vegetable oil were added to each blend and thoroughly mixed to form a dough. The dough from each blend was steamed for 20 min to partially gelatinize it and pressed manually through home pasta making machine. Pasta made from these blends were subjected to proximate analyses, sensory evaluation, mineral determination and physical properties evaluation. The result of the proximate composition showed significant (p < 0.05) variation in all the parameters measured. Also, various blends significantly influenced the mineral composition of the products. In physical properties, pasta products were significantly different in height, thickness and expansion ratio but, not significantly different (p > 0.05) in deformation strength. The sensory properties of the pasta products were significantly (p < 0.05) different from each other. However, pasta with high ratio of bambaranut flour received less sensory acceptability. Pasta with the least amount of bambaranut and cassava flour in this study compared favourably with the control. Key words: pasta, wheat, bambaranut, cassava, functiona

Cooperative research: an example from the Wet Tropics of Queensland

In recent years there has been wider recognition of the important role that Indigenous knowledge can play in developing and implementing natural resource management (NRM) strategies. The biophysical surroundings of many Indigenous peoples are of symbolic significance to them, hence their perception and values of natural resources may be vastly different to those of scientists or managers. We discuss a research approach that explicitly embraces the co-production of knowledge to facilitate NRM in Australia. We demonstrate that if particular methodologies are used and specific criteria met, cooperative research can represent one pathway for the integration of Indigenous and scientific knowledge. We suggest an important step for genuine knowledge and systems integration is in research direction-setting. Our approach practices multi-directional learning and mutual benefit, promoting cross transfer of skills by the cooperative generation and documentation of information. Indigenous knowledge and associated systems are strengthened and the value of Indigenous knowledge and systems is recognised alongside accepted scientific knowledge and methods. Essential to the methodology used is the creation of partnerships based on trust between co-researchers and the generation of genuine action research outcomes

Commission 10: Solar Activity

Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares, coronal heating etc., which are all manifestation of the interplay of magnetic fields and solar plasma. Increasingly important is the study of solar activities as sources of various disturbances in the interplanetary space and near-Earth “space weather”. Over the past three years a major component of research on the active Sun has involved data from the RHESSI spacecraft. This review starts with an update on current and planned solar observations from spacecraft. The discussion of solar flares gives emphasis to new results from RHESSI, along with updates on other aspects of flares. Recent progress on two theoretical concepts, magnetic reconnection and magnetic helicity is then summarized, followed by discussions of coronal loops and heating, the magnetic carpet and filaments. The final topic discussed is coronal mass ejections and space weather. The discussions on each topic is relatively brief, and intended as an outline to put the extensive list of references in context. The review was prepared jointly by the members of the Organizing Committee, and the names of the primary contributors to the various sections are indicated in parentheses

Metal-Rich SX Phe Stars in theKeplerField

High-resolution spectroscopic observations have been made for 32 of the 34 candidate SX Phe stars identified in the Kepler field by Balona & Nemec (2012). All available long- and short-cadence Q0-Q17 Kepler photometry has been analyzed for the 34 candidates. Radial velocities (RVs), space motions (U, V, W), projected rotation veloc- ities (v sin i), spectral types, and atmospheric characteristics (Teff , log g, [M/H], vmic, etc.) were derived from ∼160 spectra taken with the ESPaDOnS spectrograph on the Canada- France-Hawaii 3.6-m telescope and with the ARCES spectrograph on the Apache Point Observatory 3.5-m telescope. Two thirds of the stars are fast rotators with v sin i > 50 km/s, including four stars with v sin i > 200 km/s. Three of the stars have (negative) RVs > 250 km/s and retrograde space motions, and seven stars have total space motions > 400 km/s. All the spectroscopically measured SX Phe candidates have positions in a Toomre diagram that are consistent with being bona fide halo and thick-disk stars. Although several stars show a marked metal weakness, the mean [Fe/H] of the sample is near 0.0 dex (σ ∼ 0.25 dex), which is considerably more metal-rich than is normally expected for a sample of Pop. II stars. Observed pulsation frequency modulations and optical time delays suggest that at least eight of the SX Phe stars are in binary systems, some of which show signif- icant RV variations. Six of the time-delay binaries have secondary masses ranging from 0.05 to 0.70 Mo and orbital periods in the range 9 to 1570 days. Another star appears to be an ellipsoidal variable with a 2.3-day orbital period; and two other systems have orbital periods longer than the ∼4-year sampling interval of the Kepler data
