Experiments were conducted in November and December, 1981, at three commercial growing sites in New South Wales (Duranbah, Medowie and Richmond) to evaluate the yield and quality of eight determinate cultivars of fresh market tomatoes. Flora-Dade, which is the most widely grown commercial cultivar in Australia, was included as a control. Over all sites, Sunny, Duke and Royal Flush were the highest yielding cultivars, with increases of 25, 22 and 20% respectively, over Flora-Dade. Sunny was the highest yielding cultivar at Medowie and Richmond. Fruit for quality assessment was harvested at an early colour stage and ripened at 20�C. Fruit of Flora-Dade was firmer than all other cultivars. Sunny and GS393 had similar shelf life to Flora- Dade. Chemical composition and sensory tests showed little differences between cultivars.

The aim of the experiments described in this paper was to identify determinate cultivars suited to production of fresh market tomatoes on raised beds in the inland irrigation areas of the south-west area of New South Wales from January to April. Cultivars that produce high yields of first-grade medium to large fruit, and are smooth, nearly round, firm and an even bright red when ripe are required. The plants should have good leaf coverage to prevent sunburn, and jointless pedicels to facilitate harvesting. The period of maturation of the fruit should be short to permit recovery of the crop with a maximum of 3 harvests. Ten lines including Sunny, a .reference cultivar with jointed pedicels, were evaluated at Richmond in the Sydney Greater Metropolitan Area and at Leeton in the Murrumbidgee Irrigation Area, 1984-86. The lines were trickle-irrigated and mulched with black polyethylene film except at Leeton in 1985-86 when a trickle-irrigated, no mulch treatment and a furrow-irrigated treatment were included. The experiments showed that it is possible to produce yields of 50-100 t ha-1 of first-grade fruit with trickle irrigation. No significant advantage was obtained at Leeton in 1985-86 by using polyethylene mulch; however, the mulch largely eliminated the need for hand-chipping of weeds from among the plants. The visual quality of fruit grown at Leeton was excellent but total soluble solids levels were low, ripe fruit were unexpectedly soft, and sensory scores for flavour and general acceptability were only satisfactory. Overall, 2 cultivars that have jointless pedicels, Red Chief and Delta Contender, showed promise. A jointless hybrid line, HARU 83-148, which was bred at Richmond, warrants further evaluation. Some signs of incipient field chilling of fruit were observed at Leeton in fruit harvested after the first week in April.

Ripe Stage

Four new F1 hybrids which incorporate the ripening inhibitor (rin) tomato mutation were compared with standard commercial tomato cultivars, including Flora-Dade, for the fresh market in New South Wales and Victoria. The rin gene, in the heterozygous condition, delayed the start of ripening by a few days, increased the interval between breaker and full ripe from 5 to 7 days compared with commercial cultivars, and increased the storage life of ripe fruits from 28 to 40 days at 20�C. There were no significant differences between the level of red colour developed by the rin hybrids and reference tomatoes; however, the rin hybrid fruits took 4 days longer to reach full red colour. The fruits of rin hybrid were as firm as the reference tomatoes when picked at breaker and stored at 20�C for 6 days. However, rin hybrid fruits were significantly (P<0.05) firmer than those of reference tomatoes when harvested at a full ripe stage. Of the 4 rin hybrids tested, HRAS 87-70, which showed the most promise, was released in February 1990 as 'Red Centre'.

The Mean

The yield and quality of a diverse range of cotton hybrids was measured in one, or more, of a number of experiments conducted in the Ord River valley, Western Australia (15�S.) and the Namoi River valley, New South Wales (30�S.). Two of the experiments were diallels, one involving nine parents, the other thirteen parents. In both the plant and subsequent ratoon crops, mean yield of the hybrids was significantly greater than the mean yield of the parents, and the hybrids had significantly longer and stronger fibre. A few hybrids in both diallels significantly outyielded commercial controls by between 15 and 35% in both the plant and ratoon crops. Subsequently, in other experiments including one with near-commercial large plots, the high performers from the diallel experiments were inconsistent for yield, usually exhibiting little or no heterosis above that of the best commercial cultivars. Other hybrids tested in these experiments also generally failed to outyield the commercial controls, although a number had higher-quality fibre. It was concluded the heterosis for yield is not consistent enough under high-yielding Australian conditions to warrant the commercial production of hybrid cotton seed. Some hybrids, however, especially the interspecific G. hirsutum x G. barbadense ones, have the stronger, finer fibre that appears better suited to cotton spinning equipment now being developed, and this aspect could justify reappraisal of this conclusion in the future.

Postharvest vacuum infiltration of calcium into mature but unripe Hass and Fuerte avocados obtained from 80 growers in the 3 major growing districts in Australia over 2 seasons delayed the time to ripen compared with untreated fruit; but the magnitude of the response varied. Hass fruit from 66% of growers in the Murray Valley showed a significant delay in ripening and the average increase in fruit from all growers was 45% over that of untreated fruit. The response of Fuerte fruit was similar between districts, with an average delay in ripening time of about 30% and with fruit from 60% of growers having a significant increase. Hass fruit from North Queensland and northern New South Wales gave the lowest average delay in ripening of about 10% and an increased delay was significant for fruit from 25% of growers. The quality of ripe Hass fruit was not affected by calcium infiltration, whereas a slight decrease in the quality of Fuerte fruit was observed.

Garlic is primarily grown for its cloves used mostly as a food flavoring condiment. Previous studies carried out on plant density indicate its direct influence on yield. Plant density depends on the genotype, environmental factors, cultural practices, etc. This study was established to determine the effects of different between-row spacing on growth, yield, and quality of four local accession of garlic. It was laid out on two-factorial Randomized Complete Block Design with three replications during two years. Four local accession of garlic (Langroud, Tarom, Tabriz and Hamedan) were culture in three between-rows spacing (15, 25 and 35 cm) during two years. The results of two cultivated years were different. Plant density changed when garlic cultured with different between row spacing. In present research plant yield increased when the lower between row spacing and high plant density were used but the yield improvement occurring at increased plant stand is offset by the reduction in bulb size and some quality indices such as total phenol and antioxidant which severely affects quality and market value, when garlic is produced for fresh market.

Depth Interviews

With proliferating efforts to regulate the quality of cannabis on legalized markets, and recent discussions about drug quality assessment by darknet buyers, it seems timely to explore definitions of the quality of cannabis among consumers. An inductive analysis of in-depth interviews with people who had used cannabis in the past 12 months was conducted, which focused on the respondents’ subjective definitions and assessments of the quality of cannabis. The data are drawn from convenience samples in four localities (Florida [United States], Czechia, Spain, and New South Wales [Australia]) where cannabis was illegal or decriminalized. The findings suggest that the respondents across all four localities used a range of visual and sensory indicators to assess the quality of cannabis. For many respondents, these were independent indicators of the quality of cannabis suggesting that cannabis was not merely an “experience” good. For others, visual and sensory assessments were used as indirect indicators of quality in that they represented the effect of the cannabis. The desired effect was more complex than simple potency (strength) and several respondents preferred mild and not-sedating cannabis. Across the four localities, the respondents also included “proxy” indicators of the safety of cannabis in their definitions of quality. In other words, high-quality cannabis was defined as not causing excessive intoxication or physical harm. Altogether, cannabis was a specific “credence” good when its quality was seen as a result of cultivation techniques, production location, or producers’ (profit) motivations - depending on the locality. These findings suggest that cannabis policies that regulate the cultivation process can be relevant to people who use cannabis. Given that consumers take the safety of cannabis into consideration when assessing its quality, their involvement in the development of quality standards is warranted. Consumer-led self-regulation should also be considered in policies that seek to regulate cannabis supply.

Lamb Growth

Pasture production, ewe and lamb growth, ewe wool production and diet quality were studied on lucerne-subterranean clover pastures at Wagga Wagga, New South Wales. Lucerne was sown at rates of 0.75 to 3.0 kg/ha, and the pastures were rotationally grazed with Border Leicester x Merino ewes at 9.6 or 12.7 sheep/ha, the ewes lambing in August- September. Lucerne density declined by 45% over the 3 years on all treatments. The clover cultivar sown, Woogenellup, had low persistence, particularly at 12.7 sheep/ha. The density of lucerne had little effect on annual wool and lamb production, although the ewes grew faster on the denser lucerne in summer and the sparser lucerne in winter. At 12- 7 sheep/ha, there was an extra 19% total lamb weight by the end of November and an extra 22% of finer wool (1 �m) annually, but the fleeces had a higher proportion of wool tenderness. The major limitations of the lucerne-subterranean clover pastures to sheep production were the low quality of the diet in early summer, and low pasture production in late winter. In early summer the lucerne was rapidly consumed, leaving only moderate quality clover and grass residues, which limited lamb growth, while in winter pregnancy toxaemia occurred, fleeces were tender and wool growth was low, particularly during a drought in 1976.

Selection Of

Information on the features to be protected in a system of conservation reserves is an obvious requirement. The quality of the data base will primarily determine the effectiveness of conservation planning in protecting the full range of natural features in a region. However, the way in which data are used to make decisions on the locations of protected areas is also critical. Rigorous procedures for reserve selection can make the difference between achieving reservation goals or not. Research on reserve selection in New South Wales over recent years has concerned both data bases and procedures for guiding decisions. Reserve planning in many regions is based largely on some form of land classification like vegetation types or land systems. There are good reasons for using such land classes to guide the selection of reserves and to judge their representativeness. Nevertheless, they can have considerable limitations as a basis for protecting all the species in a region. These limitations are reviewed with references to more detailed discussions of particular issues. The paper also reviews a variety of procedures for selecting reserves which have been tested and applied in New South Wales. Some of the recent procedures are conceptually simple but very useful in identifying the requirements of reservation goals and demonstrating the options available to planners for representing particular features. Three principles are proposed which should underpin any attempt at systematic conservation planning.
