Seedling rot or clump rot

This disease is similar to the rhizome rot disease of plantations. Usually, the disease is observed in nurseries where the seedlings attain an age of 6-12 months and is often seen during rainy season in overcrowded nurseries. The disease symptoms are characterized by wilting and drooping of leaves. Leaves turn pale yellow, followed by rotting of the collar portion of seedlings. As infection advances the young tillers fall off and the entire seedling collapses. The causal organisms reported are...

Minor pests

These occur on underground rhizome of the L.cardamom plants. They feed on the roots and rhizome part of the plant and cause yellowing during summer months. The pest is recorded at Neem (East Sikkim), Tarku (South Sikkim), Chawang (North Sikkim) and Singling (West Sikkim) in March-October. Heliothrips haemorrhaidalis Bouche (Thysanoptera Thripidae), is a minor pest on leaves, infests the undersurface of leaves and suck the sap. The damage is more on seedlings and are recorded throughout the...

Nutmegclovecardamom mixed cropping system

Nutmeg, clove and cardamom tap solar radiation at different heights and so also mine soil moisture and nutrients at different vertical and horizontal spaces. Instead of planting other forest tree species, clove and nutmegs planted in vacant, open areas can provide sufficient shade to cardamom. This crop combination is ecologically feasible and economically sustainable. An example of such a cropping system is available at Burliar at an elevation of 3500 feet above MSL in Tamil Nadu state. This...

Biotechnology 61 Micropropagation

Micropropagation offers tremendous scope for rapid vegetative propagation of elite clones or varieties, eliminating systemic pathogens such as viruses. Replanting of senile, seedling-raised plantations with selected high yielding clones multiplied through micropropagation can give 5-6-fold increase in the current average productivity of cardamom (Anonymous, 1996). Micropropagation technique can be used for the following applications in cardamom (Bajaj et al., 1988). (i) increase in the...

Cardamom As A Spice 41 Cardamom for culinary use

The major use of cardamom on a worldwide basis is for domestic culinary purposes in whole or ground form. In Asia, cardamom plays an important role in a variety of spiced rice, vegetable and meat dishes. Cardamom can add a lingering sparkle to many dishes, both traditional and modern. International trade in cardamom is dependent, however, on the demand created by specialized applications that have evolved in two distinct markets, namely the Arab countries of the Middle East and in Scandinavia....

Polybag nursery

Polythene bags of 20 X 20 cm size and thickness of 200-300 gauges with six-eight holes can be used for raising cardamom seedlings. Bags may be filled with nursery (pot) mixture in the ratio of 3 1 1 of jungle topsoil, farmyard manure and sand. The bags are arranged in rows of convenient length and breadth for easy management. Seedlings of 3-4-leaf stage can be transplanted in bags. Later, in between bags adequate space may be provided for better tillering (Fig. 4.4). The advantage of raising...

Propagation through seeds

In order to get quality seedlings, cardamom nursery has to be managed carefully and scientifically. This involves sowing seeds on raised beds, transplanting into primary and then to secondary nursery beds and finally into the field (Cherian, 1979 Kasi and Iyengar, 1961). Seeds should be collected from high yielding vigorous plants, with well-formed compact panicles and well-ripened capsules free from infestation of pest and diseases. Number of flowering branches formed on the panicles,...

Antiinflammatory activity

Yamada et al. (1992) reported that cardamom showed potent complement system activating property. Complements represent the humoral arm of natural immunological host-defense mechanism and are essential for survival. Once activated this kills certain bacteria, protozoa, fungi and virus as well as cells of higher organism. Thus complement activation forms a major part of natural defense affording a range of mediators possessing immuno-inflamatory potency. Jain et al. (1994) have shown that the...

Plant nutrition

In L. cardamom, much of the nutrients are removed by leafy shoots and very less by capsules and spikes. It is observed that robust varieties like Ramsey, Sawney etc. remove almost double the quantities of nutrients as compared to non-vigorous ones like Dzongu Golsey. It is estimated that for producing about 100 kg dry L.cardamom, the robust types remove (in kg) 10.33 N 1.95 P 26.24 K 19.10 Ca and 11.9 Mg whereas Dzongu Golsey removes only about 5.74 0.99 3.54 9.18 and 5.86 of NPK, Ca and Mg...

Secondary nursery

In Kerala and Tamil Nadu regions the seedlings are transplanted to secondary nursery beds when they are about 6 months old, where as in Karnataka, the practice is sowing seeds in the primary nursery and thinning out excess seedlings and then allowing the remaining ones to grow right in the same place. Transplanting seedling to secondary nursery reduces nursery diseases. Korikanthimath (1982) has shown that following both primary and secondary nursery practices would be needed to get vigorous...

Conclusion Of Medicinal Plant

Though cardamom is a perennial crop, its growth behaviour resembles more to a biennial crop in the sense that vegetative phase (tillers) emerging in one year turns into reproductive phase during the second year and produce panicles, flowers and capsules. Cardamom, being cultivated as an undergrowth with shade trees, competition for inputs among them makes nutritional management an important practice in realizing optimal yield of the crop. Escalation in cost of fertilizers makes necessary their...

Spacing

The spacing should be decided based on variety and duration of the crop in the field. Where it is intended to grow on a limited cycle, with regular replanting, it is obviously desirable to plant as closely as possible without unduly restricting the plants, so that early crops may be as large as possible. If a crop is only meant to last for 10 years, a commonly suggested crop cycle, only eight harvests are likely to be taken and the first two at least will be dependent on the number of plants...

Economics and labour utilization pattern of sole forest vs forest cultivated with cardamom

It is worth comparing the additional benefits accruing from cardamom cultivation beneath shade trees. An evergreen forest in the Western Ghat region managed ideally (sole forestry system) can yield 10 m3 of timber hectare annum. Our present yield is much below this level. At present the returns will be approximately 10 times more due to increase in timber cost. Moreover clearing of forests for non-forestry purposes is not permitted now. Computed over a period of 20 years, the net returns from...

Water harvesting

Often the terrain of cardamom estates is undulating with moderate to steep slopes. Quite a number of small and fairly big streams pass through many of these areas. Runoff from the cardamom watersheds can be collected in farm ponds and check dams or underground water tapped through dug wells. Harvested water can be stored in ponds and checkdams by minimizing the losses through seepage, evaporation and recycling. Apart from improving and stabilizing yields under rainfed cardamom cultivation,...

Methods of irrigation

Among the various methods of irrigation viz., surface irrigation, sub-surface or trench irrigation and overhead irrigation or sprinkler irrigation, the last one is ideally suited in cardamom plantations. Overhead irrigation with sprinkling unit is found well suited for cardamom on account of its several advantages over other irrigation methods. Cardamom is grown on hill slopes with undulating topography and for such land, sprinkler irrigation can provide uniform water supply. The plantation can...

Root grubs Basilepta fulvicorne Jacoby

Isolat Beauveria Bassiana

Root grub is a serious subterranean pest of cardamom Fig. 8.5a,b . It damages roots and thereby obstructs uptake of nutrients, leading to yellowing of leaves and gradual death of plants in case of severe infestation Gopakumar etal., 1987 . The pest is noticed both in nurseries and plantations of Kerala, Karnataka and Tamil Nadu Varadarasan et al, 1988 . However, in Karnataka Thyagaraj et al. 1991 observed it as a serious pest only in the primary and secondary nurseries. Biology and management...
