E. camaldulensis, E. urophylla, E. saligna and E. tereticornis plantations in Amlai region of Madhya Pradesh through seed route were raised from Australian seeds procured from Australian Tree Seeds Centre CSIRO Division. MAI achieved after seven years of growth was maximum in E. saligna followed by E. camaldulensis, E. urophylla and E. tereticornis. E. urophylla and E. saligna wood of seven years of age need 2.0% more alkali than E. camadulensis and 1.0% than E. tereticornis in cooking operation to produce bleachable grade pulp. E. saligna is better in MAI and bleached pulp strength properties than other Eucalyptus species. E. camadulensis was observed to be inferior in respect of unbleached and bleached pulp yield and various physical strength properties than other Eucalyptus species.

Componentwise biomass production and the distribution of nutrients at the age of 4, 7 and 10 years of Acacia mearnsii plantation is presented. Linear regression analysis was carried out. Among the prediction variables tried, D2H was found to be the most reliable parameter for prediction purposes. The total above-ground biomass produced at 4, 7 and 10 years of age by class A was 20.4 t/ha, 27.1 t/ha and 151.4 t/ha; and 64 t/ha, 45.6 t/ha and 21.9 t/ha by class B respectively. Harvesting of utilizable biomass (wood. bark and branches) would result in the removal of 385 kg/ha (N), 4 kg/ha (P), 300 kg/ha (K), 205 kg/ha (Ca) and 50 kg/ha (Mg). Leaving leafand twig components at the site would not compensate the drain off. Some safeguard in terms of fertilization etc. is suggested, while raising the plantations of Acacia mearnsii.- Biomass Production and Nutrient Distributlon in Five Years Old Plantation Ecosystems of Fodder Species in Rajasthan

Studies on biomass production and nutrient distribution in plantation of Acacia nilotica, Acacia tortilis and Leucaena leucocephala under unirrigated and irrigated conditions have been undertaken. The biomass in irrigated areas was found to be much higher as compared to the unirrigated areas. Maximum accumulation of nutrients is observed in leaf and twig components in both areas. Some safeguard in terms of fertilization etc. have been suggested while raising the plantations of these species.- Forest Productivity Research-Case Study of Eastern Part of the Country

This paper presents the case study on work done on biomass production of some monocultures raised in eastern part of the country. Comparative total biomass and the timber production of Eucalyptus hybrid, Pinus patula, Pinus kesiya and Cryptomeria japonica have been discussed. Further studies to obtain more reliable and authenticated data on productivity has also been suggested.- Biomass Estimation and Distribution of Nutrients in Five Different Aged Eucalyptus grandis Plantation Ecosystems in Kerala State

Above and below-ground biomass and distribution of nutrients of five different aged stands of Eucalyptus grandis have been discussed. Correlation coefficient and regression models were worked out separetely for each biomass component, total above-ground and total biomass. Among the predictor variables tried, D.B.H. was found to be the most reliable parameter for prediction of biomass. The results were significant at 0.01% level of probability. The total standing biomass of these plantations ranges between 65 t/ha to 302 t/ha. An estimate has been made of the quantity of nutrients immobilized in the crop. The quantity of nutrients removed permanently from the site has also been discussed. Leaving foliage and debarking at the site has been suggested to check the deterioratlon of the site to some extent.- Biomass Production in Plantation Ecosystem of Ailanthus excelsa at Five Different Ages in Uttar Pradesh

The biomass production of 3, 6, 11, 16 and 21 years old plantations of Ailanthus excelsa has been discussed. Regression equations were worked out, it was observed that log models of type Log y = a + b log × are well suited for the prediction purposes. The peak values of biomass 41.8 t/ha and 40.3 t/ha were obtained at the age of 6 and 11 years respectively. The decreasing biomass of leaf and twig component with increasing age has also been discussed. Study on return of nutrients in these plantations has been suggested.- Biomass Production and its Distribution by Acacia nilotica Plantations at Five Different Ages in Haryana

The distribution of biomass of Acacia nilolica at five different ages, in Haryana has been discussed. Prediction models were worked out seperately for each biomass component and the total above ground biomass. Linear model was found to be the best fit. Among the prediction variables tried D2 was found to be the most reliable parameter for prediction of biomass. The total above-ground biomass ranges from 36 t/ha (5 years) to 307 t/ha (17 years). The above-ground biomass increases sharply after the age of 13 years.- Distribution of Nutrients in an Age Series of Eucalyptus and Acacia auriculaeformis Plantations in Bihar

The distribution of nutrients in plants and their losses by way of harvesting have been discussed in an age series of plantations of Eucalyptus and Acacia auriculaeformis. Considerable amounts of nutrients are retained in the leaf and twig components, which should be left over in the field to minimise the nutrient drain. Debarking in the field, if possible, will further reduce the drain up to some extent. Comparatively much higher amount of nutrients are retained in the leaf and twig components of Acacia auriculaeformis, as against Eucalyptus. Thus raising of these species alternately on the same site is suggested to protect the ecosystem from degradation and allow optimal yield with the available mineral resources at a particular site.- Biomass Estimation of some of the Tropical Pines with Special Reference to Pinus kesiya

The paper summarises the studies conducted in respect of the tropical pines regardiog biomass producction. An atttmpt has been made to furnish the brief details about the biomass studies of Pinus potula. Pinus elliottii and Pinus roxburghli in different localitles in the country. The object has been to compare the total above-ground biomass and of the different components of exotic pines with the indegenous pines. The results of these studies can be made use wherever these pines have given promising results to solve the demand of raw material for paper & pulp. fuel, and firewood requirement of the villages and they can also be put to other variety of uses to ease out the pressure on tbe indegenous species of our natural forests.- Organic Matter Production and Distribution of Nutrients in Eucalyptus Hybrid Plantation Ecosystems in Karnataka

Studies on biomass and nutrient distribution have been carried out in an age series plantations of Eucalyptus hybrid in Karnataka. The total above-ground biomass ranged from 19 t/ha to 22 t/ha in Kolar Forest Division and 5 t/ha to 16 t/ha in Madhalli Afforestation Centre. The componentwise distribution of nutrients has also been discussed. A substantial amount of nutrients will be drained off as a result of whole tree harvesting. Some advantage could be gained by leaving follage at the site which contains on an average 30 to 40% of macro- nutrients. Debarking at site is also suggested to check the drain of Ca. Total biomass and nutrient accumulation in ground vegetation, which is gradually made available to the trees has also been discussed.- Biomass Production and its Distribution in an Age Series Plantations of Eucalyptus Hybrid and Acacia auriculaeformis in Bihar

The distribution of biomass in various tree component and productivity in an age series of plantations of Eucalyptus and Auriculaeformis have been discussed. For comparable ages the utilizable biomass recorded for Eucalyptus was higher than Acacia auriculaeformis. The maximum biomass produced at the age of 5 years in Eucalyptus has also been discussed. The present study suggests to raise Eucalyptus and Acacia auriculaeformis alternately in the same site, to maintain the fertility status of the soil to same extent.- Forest Education at University Level and its Orientation
