Abstract

Physical and Mechanical properties of plantation grown Leucaena leucocephala obtained from Andhra Pradesh and F.R.I. Dehra Dun have been evaluated on the basis of tests done on small clear specimens in green and dry conditions. Suitability indices and Safe working stresses have also been calculated. It's grouping according to strength and classification for different end uses from strength point of view have also been done as per existing criteria. On the basis of strength, the timber is found suitable for structural use, door and window shutters /frames, furniture and cabinet making, flooring, tool handles, packing cases, dunnage pallets and expendable pallets etc.

Abstract

Collection and marketing of medicinal and aromatic plants is a highly labour oriented activity. Only right holders are allowed to collect these products. Illegal collection and marketing of the produce, however, also takes place; and the State Forest Department has taken some steps to check this practice. 'Dhoop'
(Jurinea macrocephala) and 'Karu' (Picororrhiza kurrooa) are the two important items collected in the area. These are followed by 'Thuth'
(Salvia moorcroftiana), 'Banafsha' (Viola serpens) and 'Patish' (Aconitum sps.) respectively. Collectors' net share in consumer's rupee for different products is low and ranges from about 14 to 23 per cent for 'dhoop' and 22 to 28 per cent for 'karu'. Marketing channel, Collectors. Contractor - Broker - Wholesaler - Consumers was noted to be widely in use. Contractor's margins were also noted to be high. Labour charges are the major component of collectors' cost and account for about 17 and 10 percent of the consumer's price for 'dhoop' and 'karu' respectively. The study points out the need to curb the practice of unscientific extraction of this forest wealth. In order that the collectors get remunerative prices, marketing of M&APs need to be streamlined and cooperative efforts may be promoted. This will help in creating a say in the market for collectors of different M&APs from the State; who individually are only small-lot sellers.

Abstract

Establishment of successful agro-forestry plantations in fragile eco-systems such as eroded soils is a difficult job as it involves relatively higher cost and generates less returns. Site specific benefit-cost studies for plantations on such sites thus are important. The present study was undertaken in the Upper-Swan river catchment area of Una District in Himachal Pradesh. This catchment area is peculiar for its eroded soils. Tree species, Dalbergia sissoo, Albizia lebbek; Toona ciliata and Grewia optiva were considered for analysis. Plantations being sparse the calculations were done on per 100 tree basis at relatively higher (12%) rate of returns. Results indicated that the plantations under consideration were profitable as both, Net Present Worth (NPW) and the Benefit. Cost ratio (B.C ratio) criteria testify it. Grewia optiva being very popular and useful fodder species of the area, yielded the highest NPW (Rs.11,644) followed by Dalbergia sissoo (Rs.5,611), Toona ciliata (Rs.5,155) andAlbizia lebbek (Rs.3,350). However, the B.C ratio was found to be the highest for Dalbergia sissoo (2.59) followed by Toona ciliata (2.58), Grewia optiva (2.35) and Albizia lebbek (1.97).

Abstract

Success of farm-forestry programme are crucially linked to their economic profitability. Eucalyptus is a prominent component of farm-tree plantations in Punjab as in many other parts of India. These plantations in the beginning stages raised hopes for fast and substantial returns. However, now when the plantations are maturing, the expectations of high returns are not being realised. Doubts are being raised about the economic compatibility of Eucalyptus as a farm component in this agriculturally progressive State of India. This paper evaluates Eucalyptus marketing system in Abohar, Ludhiana and Patiala markets of Punjab. Lack of efficient marketing system is belived to be major factor in depressing returns from Eucalyptus plantations. The results of the study confirm the theoretical relationship of decline in producer's share in consumer's rupee, with the increase in length of marketing chain. Intermediaries' margins are found to be significantly high. The study suggests the need for reviving marketing system and also keeping policy promises to maintain farmers' enthusiasm for the success of any innovative Farm Forestry Plantation Programme.

Abstract

Physical and Mechanical properties in green, air dry and kiln dry conditions based upon tests conducted on small clear specimens obtained from ten logs of Bischofia javanica (Uriam) from Arunachal Pradesh have been reported. The results obtained have been compared with 'Standard Teak' (from Malabar, Nilambur and Coimbatore). Suitability indices have been reported. And compared with the coresponding values of'Standard Teak'. Expected values based on specific gravity-strength relationship have also been reported for the sake of comparison.

Abstract

In the present paper an attempt has been made to study different factors affecting fuelwood consumption. The extent of dependance on forests for fuel-wood, at a village level has also been estimated by using the survey data. The study was conducted in the higher hills of district Shimla of Himachal Pradesh during the summer season of 1985. The study revealed that firewood is the only source of cooking energy in the area. It has been found that the number of meals cooked in a day has got significant effect on the fuelwood consumption followed by the number of persons per hearth. The effect of availability of fuelwood from owned sources has not been found to be significant. Further, for more than 80 per cent of their fuel- wood requirements villagers were found to depend on forests and about 15 per cent of fuel-wood requirement is being met from owned sources.

Abstract

Physical and mechanical tests were done in green and kiln dry conditions on small clear specimens obtained from 9 logs of cinnamomum camphora received from New forest, Dehra Dun. The relults obtained have been compared with Teak. It is found that valuel are lower than standard teak in general. Estimated values based on strength specific gravity formulae hive also been compared with observed values in green condition. The observed values are higher than estimated. Safe working stresses and suitability indices based on specific gravity have also been reported and compared with the corresponding values of Teak.
