The priority areas of concern call for reorientation of forest management policies and development programmes in the context of environmental security and maintenance of biological diversity. What is increasingly evident is the need to expand the forest resources base and productivity, besides effective involvement and participation of local communities in establishing sustainable forest management systems. NGOs have essentially been playing the role of a facilitator in bridging the gap between forest dependent communities and the Forest Departments catering so far primarily to sociological aspects of development projects. Forestry research will essentially require relevant government agencies, Universities, NGOs and grassischolar_main organisations to collaborate on action research, training and information sharing activities. A good networking of organisations coupled with effective extension mechanisms would be a successful combination. Constraints to effective NGO involvement in forestry development programmes stem from misunderstanding of NGO strengths and weaknesses, contractual and funding hurdles such as finding a way to channel funds to NGOs in advance, mutual distrust, and the lack offin many cases non-recognition of managerial and technical skills among many NGOs. Special programmes are needed to strengthen NGOs to enable them to play a greater supporting role in the Forestry sector. For NGOs to play an effective and meaningful role, coordination and collaboration for forestry research and extension could be at various levels from the grassischolar_mains to the policy making level.

Comparative transpiration rates of siz Eucalyptus species viz. E. teretlicornis, E. hybrid, E. paniculata, E. robusta, E. albrz and E. saligna, under adequate moisture and stress conditions were studied along with their water deficit percentages. The results show that E. tereticornis, and E hybrid not only have lower rates of transpiration both under adequate moisture and stress conditions, but also possess inherent tissue characteristics to maintain higher level of hydration even under stress conditions. It is concluded that these two species tnay be more drought tolerant as compared to other species investigated.- Organic Matter and Plant Nutrients in a Teak (Tectona grandis) Plantation

This is a brief survey of the information available on the effects of Eucalytpus plantations with particular reference to water relation and soil nutrition. It appears that their benificial effects out-weigh any possible adverse effects and the complaints regarding the adverse effects of Eucalyptus plantations on water supply is rather exaggerated.- Nature Reserves in India

One of the most spectacular examples of soil erosion in India is found along the Chambal and Yamuna rivers and the Kothar lands of Gujarat State, where erosion is caused by the formation of gullies and ravines through the unwise use of man and his domesticated animals coupled with the action of rain and flowing water. Though the magnitude of tbe ravine problem in India has not been correctly assessed, it is estimated that about 30,00,000 acres of culturable lands are effected by the ravines in the country out of which 7-8 lakh acres are found in the State of Rajasthan alone; the area being on the increase annually. The actual area in need of immediate anti-erosion measures in the state due to the formation of ravines and their extension is nearly 49-56 lakh acres. With the increasing pressure of human population, India can ill-afford the luxury of leaving these ravines as vast blanks or indifferendy stocked. The best and the most important and economical use of these ravines would be to use them for raising fuel, fodder and small timber, which is the crying need of the day, thereby direct all the cow-dung to the farmer's fields. Mechanical reclamation of these lands, for ralsing agricultural crops, though a possibility is extremely expensive, even excluding the cost of the post reclamation works, and may be recommended only at places, where perennial irrigation and suitable markets for the cash crops which would be grown on such reclaimed lands exist. This cannot be said with any certainty in the absence of any reliable figures for the cost of reclamation of ravines in the country. It, however, does not affect the use of these ravine lands for fuel, fodder and small timber as that holds its primary place in our rural economy because after all people in the villages have to be given timber for shelter, fuel for their cooking and fodder for their cattle.- Forage Yield Fltom Ciiambal Ravines

Nearly three million acres of culturable land in India are affected by ravines, out of which nearly 14,00,000 acres are found in the States of Madhya Pradesh and Rajasthan alone along the Chambal river system. Mismanagement of these lands over long periods of time, coupled with the action of rain and flowing water has rendered these fertile alluvial plains completely barren and un-productive to present a devastating picture. It may be stated that these ravine lands need to be managed for the production of fuel, fodder and small timber to meet the demands of the local and outside population, which is the need of the day, rather than to reclaim them for the production of agricultural crops, at prohibitive and most un-economical costs. In the absence of any data, as to the potentialities of these ravines, for fodder production, preliminary trials to assess the forage yield production of these lands were started in 1957, at the Soil Conservation Research Demonstration and Training Centre, Kota (Rajasthan) and the results so far achieved indicate that these ravines would yield an average of 5,100 lbs. (green weight) of grass/acre after 3-4 years of simple closure.- Some Observations on Nutrition Cycle and Return of Nutrients in Plantations at New forest

It is generally believed that pure plantations are usually exacting on soil nutrients and continued rotations of the same species, on the same site, may deteriorate the site conditions considerably. The annual leaf fall, which in most deciduous species commences by about December, continues for a few months and may even linger on till the rains, brings back some proportion of these nutrients to the soil, but the exact quantities so involved are not known for Indian species. The matter needs all the more attention in view of large scale afforestation of degraded areas in the country with fast growing short rotation species. A preliminary investigation in this regard was therefore considered necessary and data were collected from teak (Tectona grandis), sal (Shorea robusta), chir (Pinus roxburghii), Araucaria cunninghamii and bamboo (Dendrocalamus strictus) plantations at the F.R.I., during the period November, 1960 to June, 1961.- Bamboo in Chambal Ravines

The drought tolerance of ilex (Ilex cornula var. Burfordii) and azalea (Rhododendron poukhanesis) was compared by measuring transpiration rates, water deficits, and stomatal openings of plants and leaves subjected to water stress. The transpiration rate of uowatered ilex plants declined more rapidly than the transpiration rate of unwatered azalea plants. The water deficit was considerably higher in unwatered azalea plants than in unwatered ilex plants. The stomata closed sooner and at a lower water deficit in ilex than in azalea when subjected to water stress. It is concluded that ilex is more tolerant of drought than azalea because it has more efficient stomatal control of transpiration and a higher redstance to cuticular transpiration.- Nutrition Studies on Eucalyptus I.

The paper describes the results of an investigation on nitrogen, phospborus and potassium requirements of Eucalyptus hybrid seedlings. The seedlings were grown in pots and supplied with 5 doses of N, P and K equivalent to 0, 100, 200, 300 aad 400 Iba./acre in all combinations. The seedlings showed marked deficiency symptomsin the absence or in some cases at lower levels of N and P. Survival of the plants is decreased with the increase in the dose of N while reverse is true with the increase in the dose of P, K has no significant effect on the survival of the plants. It was found that N and P each had significant effect on the growth of the plants, while reverse is true in the case of K. Interaction of these nutrients is not significant. As regards the uptake and interaction of the nutrients, the results indicate that the supply of K has synergistic effect on the accumulation of nitrogen while varying levels of N appear to show no specific trend in the uptake of K. Phosphorus uptake is not affected by the supply of N and K. The studies clearly indicate that N and P nutrients are of great importance in the growth of this species.- Nutrient Requirements of Some Casuarina equisetifolia Plantations in Maharashtra and Gujarat

The study formed a part of similar work undertaken on the species in other coastal areas where Casuarina is grown. Since in some areas mortality of Cosuarina equisetifolia was reported, it was considered necessary to know the nutrient requirements of the species coupled with soil studies, in order to find out whether the sites where the species is grown meet the requirements. Nutrient requirements of Casuarina equisetifnlia were studied by means of foliar analysis. The results indicate that there is rise in the uptake of N, K and Mg in 4 snd 5 year old crops after which there is not much variation. While Ca uptake does not show any regular trends P uptake is lower in higher age group crops. Since most of the areas where Casuarina is grown have sandy soil, it is suggested that the fertilizer application of all the minerals Except P, to 3-4 years old plantations in the form of a balanced dose may probably result in better growth in area.Where growth is found to be not up to the mark.- Nutrient Uptake of Fir (Abies pindrow) and Spruce (Picea smithiana)

Nutrient uptake of middle-aged fir (Abies pindrow) and spruce (Picea smithiana) stands was studied with the help of plant part analysis. Representative samples of leaf, bark and wood of these species were collected from typical localities in Kashmir valley, Kulu (Himachal Pradesh) and Deoban (Uttar Pradesh) and were analysed for ash, calcium, magnesium, nitrogen, phosphorus and potassium. The results indicate that the two species do not differ much in the uptake of different nutrients in different localities.However, leaf samples of fir from Kashmir had more P and K While Ca uptake is less in wood and bark of trees from this locality. In spruce, on the other hand, Ca and N uptake are less in Deoban and Himachal Pradesh respectively. More detailed sampling on other sites and soil analysis of these localities is required to confirm the results.- Nutrition Studies on Eucalyptus. III.

The paper describes the effect of some macro-nutrient deficiencies on the growth and morphology of Eucalyptus grandis seedlings. The results indicate that deficiency of nitrogen caused stunted growth, strong chlorosis, necrosis, premature defoliation and abaence of branching, while seedlings under phosphorus deficiency, had a characteristic appearance by producing thin lateral and secondary branches with numerous small leaves, towards the end of the growing season.- Nutrition Studies on Eucalyptus.

The paper reports the symptoms on foliage and the effect on growth, branching habit and nutrient uptake caused by the deficiency of some macro-nutrients in Eucalyptus globulus seedlings. Nitrogen and potassium deficiencies produced recognisable symptoms of chlorosis and curling of leaf tips and margins respectively. There was marked effect on height growth, collar diameter and ischolar_main development which were very poor in N, P and K deficiencies. This was also reflected in dry matter production.- Forest Types Statistics

The paper describes the morphological symptoms caused by the deficiency of some macronutrients ou teak (Tectona grandis) seedlings and their effect on growth, dry matter production and nutrient uptake. The results indicate that recognisable deficiency symptoms were caused by the absence of each of the macronutrients. Unlike some other forest species studied so far, deficiency of sulphur caused distinct symptoms of chlorosis, curling of leaves and premature defoliation with restricted shoot growth. The deficiency of all the elements except that of potassium significantly reduced height growth and dry matter production.- Diagnosis of Mineral Deficiencies in Pinus patula Seedlings
