The introduction of a new crop requires adapted genotypes as well as optimum crop management practices. This study was conducted to determine the optimum crop density of adapted grain amaranth genotypes in the Pannonian region of Eastern Austria. The genotypes Neuer Typ (<i>A. hypochondriacus</i>), Mittlerer Typ (<i>A. hypochondriacus</i>) and Amar (<i>A. cruentus</i>) were established at plant densities of 8, 17 and 35 plants/m<sup>2</sup> in 2002 and 2003. Average hand-harvested yields ranged from 2200 to 3000 kg/ha without significant genotypic differences. Genotypes differed in thousand seed weight (0.55&minus;1.04 g), time from sowing to harvest (97&minus;130 days), grain water content at harvest (24&minus;38%), microbial infestation of air-dried grain (0.2&minus;118.6 cfu &times; 10<sup>6</sup>/g), germination (29&minus;79%) and grain composition. Grain contents fell within the following ranges: crude protein 15.2&minus;18.6%, crude fat 5.4&minus;8.6%, crude fibre 3.5&minus;4.2%, ash 2.7&minus;3.2%, and carbohydrates 66.7&minus;72.7%. High grain water contents involved stronger microbial infestation and reduced germination. Crop density affected neither grain yield nor grain quality.

Randomized Block Design

The present investigation was carried out to study the effect of off season soil management practices on yield and quality of turmeric (Curcuma longa L.) cultivars. The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.

Growth Development

Summary. The effect of plant density on growth, development, yield and quality of kabocha (buttercup squash) (Cucurbita maxima) was examined during 1992–93, at a field site in Cambridge, Tasmania. Plant densities ranged between 0.5 and 4.7 plants/m2. Marketable and total yields were fitted to a yield–density model. Total yield followed an asymptotic trend, approaching 33 t/ha at 4.7 plants/m2, while marketable yield had a parabolic relationship with density. Marketable yield increased to a maximum of 18 t/ha at 1.1 plants/m2, while declining at higher densities because of increased numbers of undersized fruit. Yield of vine marked and callused fruit did not vary with density, but represented a significant proportion of the total yield at all densities. High plant density reduced vegetative growth per plant due to competition for limited resources; as shown by decreased leaf area, number and length of vines, and plant dry weight. Yield tended to decline at high densities because of fewer female flowers and increased fruit abortion per plant. Plants at low densities had more vegetative growth but decreased yields, as increased abortion of fruit relative to the higher plant densities left only 1–2 large fruit per plant. Economic returns varied with plant density. At high densities, variable costs increased (particularly due to high seed cost) while gross income declined reflecting the relationship between marketable yield and plant density. The gross margin therefore declined at high densities.

Abstract This chapter describes the guava fruit as well as the fruit set, growth, drop, harvesting, yield and quality (total soluble solids, total acids and ascorbic acid). Understanding the phenological cycle of guava and the effect of management practices on yield and fruit quality allows management practices to be modified to develop strategies which should lead to productivity gains for different pruning or chemical application times. As the effects of various treatments and times of application on yield and fruit quality for different cultivars and climatic zones are known, it is possible to decide on the optimum time to apply treatments knowing what the quality of the fruit will be, the time that the fruit will be harvested, expected yield and the critical times to apply management practices.

Four maize (Zea mays L.) hybrids planted at varying plant densities were evaluated for their yield, maturity, and quality across environments in north central Alberta. Given the balance of yield and quality, very early maturing hybrids [2000 corn heat units (CHU)] planted at ~100 000 plants ha-1 are recommended for north central Alberta. Key words: Corn; Zea mays L.; northern latitudes; corn heat units
