Abstract

The tree growers of Yamunanagar District used various channels for selling their trees/produce; viz. Traders - Industries, Village level Agents/Contractors - Traders - Industries, Village level Agents/Contractors - Saw mills - Consumers, Traders - Saw mills - Consumers and Traders - Other markets of the State. It was found that 73 per cent of tree growers prefer through village agents, 23 per cent traders and only 4 per cent industries. It was also observed that socioeconomic factors such as literacy level, education and even family size do not have any significant effect on choice of market channels.

Abstract

The present study of Prosopis juliflora reflects the importance of fast growing species that will be of multipurpose character. One of the reasons for its acceptance is its adapability to semi-arid wastelands , fulewood and in the manufacturing of wide range of small and medium sized farm implements. An attempt has been made to determine the quantum of firewood that can be made available.

Abstract

Estimates of dry matter production and nutrient distribution among various biomass components in 3, 5, 7 and 9 years old plantations is presented. Regression equations for each biomass components and the aboveground biomass were worked out separately. Among the predictor variable tried, DBH alone was found to give reasonably precise values of biomass and can safely be used for prediction purposes. The total standing biomass of these stands increases with increasing age from 14.2 t/ha (3 years) to 114.5 t/ha (9 years). The component wise nutrient distribution is discussed. A substantial amount of nutrients would be drained off as a result of whole tree harvesting. However, if only utilizable (bole, bark and branch) is removed the drain would be 57, 74, 81,71 and 70 percent of N, P, K, Ca and Mg respectively, of the total aboveground biomass. Debarking and leaving foliage at the site is suggested to reduce the drain to some extent.

Abstract

Mineral cycling in four different aged Eucalyptus hybrid plantations bas been discussed. The componentwise distribution of nutrients at different ages and the nutrients removed as a result of whole tree harvesting has been presented. A total of 4565. 5242, 10236 and 9992 kg/ha of Jitter was produced annually at ages 4, 6, 8 and 10 years respectively. Out of the total litter, leaf litter contributed between 73 to 82 per cent, thus maximum nutrients are returned to the soil through leaf litter. Maximum return was observed for Nitrogen fonowed by Calcium, Potassium, Magnesium and Phosphorus.

Abstract

In this article the data for preparation ofthese tables was obtained from Muzaffarnagar road side plantations. Single tree data of 85 trees was collected. Different models were tried. The equation having the best fit for volume calculations has been used.

Abstract

Estimates of component wise dry matter production and nutrient distribution of 10,20 and 30 years old plantations of Teak (Tectona grandis Linn. F) have been discussed. Linear rtlgresssion analysis was carried out. Among the prediction variables tried, DBH alone was found to give reasonably precise values of biomass and can be used for prediction purposes. The total standing biomass ofthese stands increases with increasing age and diameter from 74.5 t/ha (10 years) to 164.1 t/ha (30 years). Maximum amount ofN, P and Mg was accumulated in hole while higher accumulation of Ca was observed in bark and ischolar_mains. Harvesting of only utilisable biomass (148 t/ha) at the age of 30 years would result in the removal of247, 41, 170, 632 and 198 kg/ha ofN, P, K, Ca and Mgrespectively. Defoliating and debarking at the site is suggested to reduce the drain of nutrients from the soil especially Ca contents.

Abstract

Joint Forest Management (JFM) in India is an attempt to reverse the process of forest degradation on one hand, and to meet people's need on the other. Forest-user communities across the country have been dependent on forests for fuelwood, fodder, small timber and NTFPs for their basic needs. Under the JFM programme these communities playa special role as they have been provided access to forest produce including NTFPs to meet their basic needs in lieu of protecting, regenerating and maintaining forest in collaboration with forest department. NTFPs are critical to JFM programme because they can be a regular source of income and employment opportunities to JFM committees. JFM Committees may take lead role in sustainable management of NTFP resources by focussing on U} collection and sustainable harvesting; (ii) processing and value addition; and (iii) marketing of NTFPs.
