Planting Date

Jerusalem artichoke can grow in nutritionally poor soils with minimal cultivation. However, good agronomic practices considerably increase crop productivity. Practices that raise tuber and biomass yields include choice of cultivar, planting date, effective weed control, fertilization, irrigation, and good harvesting procedures. 

In the southern hemisphere, planting dates run counter to those in the northern hemisphere. In southern Australia, for instance, planting occurs in September and October, with tubers harvested in March or June the following year (Parameswaran, 1994).

In gardens or allotments, tubers obtained from the grocery store could be used for planting (unlike potatoes), because Jerusalem artichoke is relatively pest- and disease-free. Tubers can also be carefully harvested and saved, stored indoors (e.g., in the dark at 0°C and 90 to 95% relative humidity), for replanting in the spring.

Orica is the largest producer of chlorine in Australia and currently operates three chlor-alkali plants on the east coast. Two of these plants (in Melbourne and Sydney) are mercury cell plants dating back over 50 years while the third plant is a small, modern membrane cell plant in the central Queensland town of Gladstone. The mercury cell plants have both reached the end of their useful economic lives.

The use of terpenoids, usually as mixtures prepared from plants, dates from antiquity. The several essential oils produced by distillation of plant parts contained the plant essences. These oils have been employed in die preparation of perfumes, flavorings, and medidnals. Examples are oils of clove (local anesthetic in toothache), lemon (flavoring), lavender (perfume), and juniper (diuretic). Usually essential oil production depends on a simple technology which often involves steam distillation of plant material The perfume industry of Soudiem France uses somewhat more sophisticated procedures in the isolation of natural flower oils since these oils are heat sensitive. The separation of oils from citrus fruit residues m California and Florida is done by machine. 

The decreasing time interval between planting and tuberization as the planting date shifts progressively later in the growing season (Figure 10.3).
