Eucalyptus are generally moderately large trees and attain a height of 40-60 feet and diameter of 40-45 inch. The trunk of the tree is generally straight and constitute half of the total height.wood is buy back with rate of kg. 5 - 6 RS/kg 300-400 kg /tree in 4-5 yrs.one tree become of minimum 1800 -2000 RS after 5 yrs. do 1200 plant in one acre at space of 1.5 X 1.5 meetre and earn RS 1800 from one tree x 1200 tree = 20,00000 - 22,00000 lakhs
Yield and Returns
In market, the poplar wood is sold on weight basis. The average wood biomass per tree after six years is about 300kg to 400kg and presently the prices vary from Rs. 4 to Rs. 5 per kg though the highest has gone upto Rs. 6/kg. Assuming an average price @ Rs.4/- per kg (under bark volume), the farmer can get Rs. 1800 - 2000/ tree/- over a period of six years. Income from inter-crops will be additional which will vary depending upon the crop cultivated. The returns will depend upon site quality, inputs, intensity of management, actual yield and ruling market prices at the time of harvest.
Eucalyptus is a fast growing tree and sub-species with several varieties and hybrids. It can be planted on agricultural lands both as monoculture and as a component of agro-forestry programmes. One of the principal factors for its widespread introduction is the ease of cultivation. Besides this, good germination and its adaptability to varying soil and climatic conditions are the other important characteristics of Euca.
II. Growth Habit
Eucalyptus trees are generally ever green trees, new leaves appear as the old ones are shed. It has no well defined season of growth and continue to grow in all seasons. It attains a height of about 30 mts and more with a straight clean bole. They have (the ability to colonize bare ground without shelter. Some of the species occurring in extremely dry areas are no higher than shrubs. The shrubs namely, E. erythrandra, E. burdethianaa and E. mitrata are 6-8 mts tall with a voluminous root system. Many of these species, when cultivated under more favourable conditions, develop into small trees.
There is a great variation in the height of various Eucalyptus , species of tree habit in their homeland ranging from 20-114 mts and girth up to 3- 4 metres.
In India, the successful Eucalyptus are generally moderately large trees and attain a height of 40-60 feet and diameter of 40-50 inch. The trunk of the tree is generally straight and constitute half of the total height.wood is buy back with rate of kg.5-6 Rs/kg 300-400 kg /plant in 4-5 yrs.one plant become of minimum 1800-2000 rs after 5 yrs.
gives fertilizers application practices in different eucalyptus growing areas.
Eucalyptus plantations require well drained, deep and fertile soils. Sandy soils may be good, provided facility of adequate irrigation is available. Choice of proper species for a particular type of site is also an important factor for the success of an Eucalyptus plantation. Specific sites suitable for different species.
1. Block planting
Eucalyptus are planted in blocks either in existing blanks or on sites containing vegetation.
In manual planting, pits of 15 x 15 x 15 cms or 45 x 45 x 45 cms or 60 x 60 x 60 cms can be dug depending on the soil and irrigation facilities. In waterlogged areas, planting on raised mounds up to one metre high is done in certain areas in Punjab, Haryana and Uttar Pradesh, usually in multiple rows along roads.
2. Row planting
Row plantations are carried out along roads, canal banks and railway lines. Along roads eucalyptus are planted behind first row of shade trees.
Irrigation and Interculture:
The irrigation pattern depends on the rainfall pattern of the area, type of soil and the objective of plantation. For quicker returns more number of irrigations are essential which may go up to 20 in number.
Climbers are a great menace to young regeneration and unless they are removed, they will spread over the saplings and smother the crowns. The climbers are to be removed along with roots, before the season of maximum growth. The heavy foliaged soft climbers such as mucuna Diascorea spp, etc. and woody species such as Acaecia spp., Mollettia, zizyphus spp. and Bauhinmia vahlii case also cause equal damage. So, reguIlar weeding practice is essential for healthy growth of the plants.
Cutting back is usually not very effective and it is more economical in the long run. These measures should obviously be taken before any seed has set and before the season of maximum growth.
