Abstract

Sapium sebiferum Roxb., an exotic source of oil seeds has now completely naturalized in Himalayan area. Domestication trials of this plant were carried out through seeds and ischolar_main suckers under two distinct habitats. Propagation occurred fairly well through seeds and ischolar_main suckers. Overall performance of the plants was comparatively better under waterlogged conditions.

Abstract

Social Forestry In Punjab is becoming very popular. Large scale plantations of Eucalyptus are being raised under Social Forestry Programme. An Eucalyptus wood based factory of 80 TPD capacity for producing medium density fibre board la being aet up In the state. About 15 to 20 lac tonnes of surplus Eucalyptus pulpwood Is available annually from the private sector. Poplar planting Is also becoming popular.

Abstract

Study was carried out on the recovery of sawn scantlings of 10.16 cm × 5.08 cm cross section from Eucalyptus tereticornis logs of different girth classes. It was inferred that for this purpose, the logs should be classified into 40-99 cm and 100-149 cm girth classes.

Abstract

In Punjab, the area under forests is extremely inadequate for meeting the requirement of the people for fuelwood and timber for individual needs The State Government has, therefore, encouraged farm and agro-forestry to increase wood production. Eucalyptus tereticornis has established itself as a timber species in the state. Poplar is another species which has found favour with the progressive farmers. The Punjab farmers have shown great zeal in raising tree crops. In order to sustain the interest in tree farming, it is necessary to set up wood-based industries which will in turn contribute significantly to the economic development of tbe state. At the same time, it is desirable to try indigenous species also so that undue dependence on tbe above species is avoided in tbe long term interest of environmental preservation. Research is therefore required in this direction urgently along with research on tbe production and utilization aspects of the established species.

Abstract

Provenance trial of Eucalyptus tereticornis Sm. Was undertaken in Ferozepur Forest Division, Punjab in August, 1982. A randomised line design with 20 treatmeats in all Including tth control was adopted for the trial. The analysis of data collected 3.5 years after the planting showed that Lekeland downs and Kennedy river.34 km N of Laura provenances of E. tereticornis, which did not significantly differ in their performance from each other were significantly superior to all other provenance in terms of volume production.

Abstract

Eucalyptus hybrid is an important species under the social forestry programme of Punjab. With a view to get more yield per unit area species-cum-provenance trials of Eucalyptus were taken up. Data regarding a four year old species/provenance trial involving three species viz. E. camaldulensis, E. tereticornis and E microtheca and five treatments have been analysed. No significant difference between treatments has been observed though the Gilbert river provenance of E. camaldulensis has, so far, given the highest basal area and volume.

Abstract

A range-wide provenance trial of Eucalyptus camaldulensis was undertaken in Ferozepur Forest Division in August, 1982. Data collected about 3.5 years after planting has been analysed. Out of a total of 16 treatments, 8 treatments (provenances) were found to be significantly superior to the control (Eucalyptus hybrid) in terms of volume production. Most of these provenances with the exception of Lake Albacutya are from the northern latitudes of Australia with latitude below 26° S.

Abstract

A study was undertaken to work out the recovery of sawn scantlings after converting the logs of different girth classes of Eucalyptus hybrid. It was observed that the number of scantlings per log, number of scantlings per m² of round timber and the per ceal recovery of sawn timber from round logs increases with increase in girth of logs. Study has suggested that eucalyptus timber should be graded according 10 girth classes 25-39 cm, 40-59 cm, 60-69 cm, 70-99 cm and 1OO-119 cm for correctly estimating the sawn out-turn in the form scantlings and also the price.
