Indian Forester, Vol 135, No 12 (2009), Pagination: 1686-1692Abstract
The floristic diversity of woody perennials was studied in Katola range of Mandi forest division in Himachal Pradesh. A total of 17 floral families contribute to the 27 species with 62.96% and 37.04% for tree and shrub species respectively. The dominant and co-dominant tree and shrub species was Pinus roxburghii, Quercus leucotrichophora and Berberies aristata, Prinsepia utilis, respectively. Distribution pattern of various tree species was contiguous except Cedrus deodara, P. roxburghii and Myrica esculenta which were random while distribution pattern of shrub species was contiguous except B. aristata. Such site-specific database is imperative as it can potentially provide fundamental information on the species organization, spatial heterogeneity, biotic and abiotic impacts on dynamics of regeneration and growth.Keywords

The effect of size of tree on the fertility of Silver fir and Spruce seed was studied. Although the cone diameters in different diameter breast height class of Silver fir differed significantly at 5% level yet cone lengths did not differ. The seed weights in different diameter breast height classes also differed significantly. However, cone diameters and cone lengths of Spruce did not differ significantly but the seed weights differed significantly. Germination percentages and germination values of seeds from different diameter breast height class trees of Silver fir differed significantly and the same values were, however, non-significant in case of Spruce.- Preliminary Studies on Germination of Birdcherry (Prunus cornuta) Seeds in the Nursery

Effect of different presowing treatments and different time of sowing on germination of bird cherry (Prunus cornuta) seeds in the nursery were studied. The results showed that different presowing treatments were not helpful in softening of stony endocarp thus showing no influence on germination. However, results of different sowing time showed highly variable chilling requirements for seeds of within and among families from a single geographical range. Thus, for optimum germination, seed sowing should be undertaken immediately after seed collection so as to ensure proper stratification of seeds in the nursery beds.- Effect of Seed Weight on Germination, Survival and Initial Growth of Horsechestnut (Aesculus indica, Colebr) in the Nursery

Tbe effect of seed weight on germination, survival and initial growth of horsechestnut in the nursery was studied. The results indicated that the medium and heavier seed weight classes performed significantly better than lighter seed weight class in terms of germination, survival, seedling height and seedling dry weights. However, heavier seed weight class gave significantly more seedling dry weights than the medium seed weight class. Therefore, the use of medium and bigger seeds of horsechestnut in the nursery for optimum germination, good survival and better plant growth as well as higher plant yield is advocated.- Seed Scarification Requirement in Indigofera gerardiana Wall

The effect of seedling size on the growth of transplanted silver fir seedlings in the nursery was studied. The studies made included observations on survival and growth of seedlings under four different height classes viz, seedlings less than 5 cm (T1); 5 cm to 7 cm (T2); 7 cm to 9 cm (T3) and 9 cm and above (T4). The performance of the seedlings below 5 cm in height in terms of survival, seedling growth and seedling dry weights was poorest as compared to other seedling height classes. The results thus indicated that seedlings below 5 cm in height should be culled at the time of transplanting.- Spade Planting-an Economical and Faster Planting Technique of Silver Fir and Spruce in Western Himalayas

In North-Western Himalayas spruce and silver fir are normally planted in pits of 30 cm3 size. This method of planting is both expensive and time consuming. Spade planting of spruce and silver fir was tried, which was assessed six times faster and also five times cheaper than pit planting. It also gave better survival than pit planting, therefore, spade planting of spruce and silver fir is recommended.- A Note on Optimum Time of Insertion of Populus ciliata Cuttings in the Nursery

An experiment was undertaken to study the effect of seedlings size on the growth of transplanted spruce seedlings in the nursery. Studies made include observations on survival and growth of seedlings under five different classes based on their hieghts viz. less than 7.5 cm; 7.5 cm to < 12.5 cm; 12.5 cm to < 17.5 cm; 17.5 cm to 22.5 cm and more than 22.5 cm. The performance of the seedlings below 7.5 cm in height in terms of both survival and growth was the poorest as compared to all other classes followed by the seedlings of 7.5 cm -< 12.5 cm height classes which also resulted in lower survival and poorer growth rate than those of the remaining three classes. Seedlings below 12.5 cm in height should, therefore, be culled at the time of transplanting.- Nursery Technology of Spruce (Picea smithiana)

The allelopathic study on silver fir and spruce showed that leachates of humus have inhibitory effects on seed germination and on radicle and plumule growth; however, litter leachates have no such pronounced effect. Foliage leachates of Sarcocoocca saligna, Viburnum nervosum and ferns (understorey plants) have more inhibitory effects on seed germination and radicle growth. It seems that leachates of fern and Viburnum nervosum are mainly respousible for very less germination on forest floor as reported in fir and spruce forests. There is no self intoxicity on germination and early growth in silver fir and spruce. The research concludes that humus and foliage of specific plants are responsible for regeneration failure in these conifers and not litter as supposed till date.Keywords

33 plus trees of Pinus kesiya were selected in an extensive survey conducted in the state of Meghalaya using point grade method of selection. Initially candidate plus trees (CPT's) along with five check trees were selected and analyzed to plus trees. During selection, phenotypic characters like stem, bole, and branching form were given more emphasis to ensure better production of timber. The plus trees over check trees could be improved by 14.75, 15.74 and 14.23% for height, girth at breast height (GBH) and crown bole height (CBH), respectively. Maximum improvement of 138.61, 105, 99, and 51.53% was recorded for crown, straightness, roundness, and pruning ability, respectively, which might play an important role in accepting this species in plantation programmes. The improvement achieved through selection may serve as an indicator for possible genetic gain after field-testing through progeny trials in the species.Keywords

The variations present in seed and pod traits, genetic superiority and genetic divergence were evaluated for a Seedling Seed Orchard (SSO) of Dalbergia sissoo Roxb. at Bithmera, India consisting of 19 progenies from the state of Uttarakhand. The seeds and pods of various progenies in the orchard exhibited significant variability in size, weight and other characters. Significant positive correlations were observed between seed length and seed weight (P<0.01), seed width and seed weight (P<0.01), seed thickness and seed weight (P<0.05), seed weight and germination value (P<0.05), seed length and germination value (P<0.05). The genetic parameters for seed and pod traits also showeda wide range of variations. Heritability values were found to be over 50 for most of the seed and pod traits, however, only seed weight showed high heritability values coupled with maximum genetic gain. Ward's minimum variance dendrogram of progenies of D. sissoo showed three distinct clusters; cluster 1 with 6 better progenies, cluster 2 with 10 moderate and cluster 3 with 3 poor progenies. Mean cluster values showed sufficient variation among the clusters for seed weight, germination value and seed length. The possibility of controlled hybridization between better progeny (288) of cluster 1 to the disease resistant progeny (304) of cluster 3 (resistant against deadly Gandoderma lucidum ischolar_main rot disease of D. sissoo) is also suggested for further breeding programmes of the species.Keywords

Kashmir valley has been witnessing an increase in allergy disorders due to aeroallergens present in the environment. Aero allergy from Populus deltoids specifically seed menace is the new addition in the list of aeroallergens in valley. The female species of the plant has left the valley sneezing and coughing ever since it started shedding seeds in the months of April and May every year. There is a sudden spurt in lung and throat illnesses, and cold and fever, during these days. The seeds are also allergic to eyes and many schools in Srinagar, capital city of Jammu and Kashmir state, have even prescribed masks to the students. The white fluffy substance - a product of poplar, cover the roads during April/May each year and is often mistaken for sleet or cotton, but go closer and it could trigger instant sneezing, a running nose and throat irritation due to allergens presence. Detail clinical studies are required to test seed menace of poplar on atopic population in the valley. The strategies and precautions to reduce this seed menace are discussed in this article.Keywords

To assess the provisioning services of CNP forest ecosystem, a questionnaire survey was conducted to know the quantity and value of non timer forest products (NTFPs) extracted from the CNP by the users of buffer zone community forests (BZCFs) during October 2012 to January 2013 in five selected BZCFs. The results showed that a total of 8275.19 tonne of biomass is extracted from the Chitwan National Park in the form of fuel - wood, fodder, grass, animal bedding, thatch / reed, fish, vegetables, medicinal plants and other NTFPs. Thatch/reed constitutes the highest quantity (48.88%) of the forest product to be extracted from the CNP followed by fuel wood (26.40%) and fodder/animal beddings (20.48%). The extraction of fish, vegetables, etc. constitutes about 2 % each of the total products. Total gross value of the forest products collected from the park is NRs (Napalese Rupee) 8,88,37000/ (888.37 <I>lac</I>) with a net value of NRs 4,12,16000/ (412.16 <I>lac</I>). The quantity of forest products extracted from the park has decreased over the years and this decrease in the extraction of forest resources could be attributed mainly to the establishment of BZCFs and the CNP has still to bear the demands of forest products of the local people.Keywords

Quercus floribunda (Moru oak) (Local name Tilonj) is an important element of western and central Himalayan vegetation. Lopping practice is very common in the forests and plantations especially near the habitation. Q. floribunda tree is lopped for fodder, which is the most appreciated among all oaks. However, heavy and indiscriminate lopping continues throughout the year which results pole like appearance of the trees with scanty leaves. Lopping of Q. floribunda results in poor production of acorns. The study suggests that there is need to understand the effect of lopping on acorn production to have sustainable lopping levels.Keywords

The seeds of Anogeissus latifolia mature in second fortnight of March each year when the seed moisture content is around 12 per cent and colour of fruits turns to blackish green. Seeds are about 95% empty when collected from the trees. The germination percentage of seeds is only 1-2 per cent; however 50% seeds are sound and viable. Seeds can easily be stored at 150 C in refrigerator in polythene bags at a moisture content of 9 per cent with slight decrease in viability up to two years. In addition to infertility/emptiness of seeds insect problem was also studied using entomological inputs. To control insect attack on fruits/seeds of A. latifolia, systemic insecticides were applied in the trees in the field and after six months of insecticide application seeds were collected from treated and untreated trees and tested in laboratory. The results showed that the number of half filled seeds was increased (about 10%) over the seeds of untreated trees; however, there was no significant increase in number of filled seeds. Increase in half filled seeds of treated trees shows the effect of systemic insecticides on the suspected insect attack in the seeds of the species. These observations showed that infertility problem in the seeds of A. latifolia are related with the insect infestation and needs further detail studies.Keywords

Realizing the importance of carbon monitoring and reporting in climate change, it becomes imperative to assess the contribution of less significant but equally important forest carbon sub-pool of shrubs and herbs in mitigating the atmospheric carbon. The present study was conducted to calculate the strata wise biomass carbon of undergrowth (herbs and shrubs) in the coniferous forests of Western Himalayan region. Quadrates of 0.1 ha were laid in six forest types and within these plots, shrub plots (5m X 5m) were laid at the opposite corners. Herb plots (herbs including freshly fallen litter) (1m X 1m) m were laid inside the shrub plots at the opposite corners for undergrowth measurements. Shrub and herb measurements were taken by total harvest method and sub-samples weighing 200 g packed tight were transferred to the laboratory and oven dried at 65 ± 5 °C to a constant weight. The estimated biomass from these plots was extrapolated to one ha. The total herb biomass hence calculated was converted into carbon equivalent using a factor of 0.50. The entire results were subjected to statistical tools using analysis of variance (ANOVA). The results revealed that shrub biomass carbon was found to be highest under Deodar (closed) strata 0.65 t ha-1 ( ±σ 0.48) and minimum under Deodar (open) 0.17 t ha-1 ( ± σ 0.20) with p<0.05. For herb biomass carbon the highest values were observed under Fir-Spruce (closed) 1.32 t ha-1 ( ± σ 0.46) and minimum under Blue Pine (open) 0.59 t ha ( ± σ 0.49) with p<0.05. The open forests were subjected to a high biotic interference as a result of uncontrolled grazing, fuel wood and fodder collection that led to the lower values for undergrowth biomass carbon. However these strata were found to have a promising potential to fix atmospheric carbon into herbs and shrubs once the conservative interventions are brought into practice.Keywords

A field experiment was conducted during Rabi seasons of 2007-08 and 2008-09 to study the realization of wheat (Triticum aestivum L.) productivity, profitability and nutrient balance sheet through improved nutrient management. Sixteen fertility treatment combinations of NPK and ZnSO4 were examined in Randomized Block Design with three replications. Application of NPK ZnSO4 @ 150 : 75 : 60 : 20 kg/ha produced highest grain yield of 51.0 q/ha being significantly higher by 71.7, 57.9, 42.5, 49.9 and 9.5 per cent over control, NPK ZnSO4 levels of 90 : 45 : 45 : 00, 90 : 45 : 45 : 20, 90 : 45 : 45 : 40 and 120 : 60 : 45 : 00 kg/ha, respectively. Further, increase in fertility levels beyond 150 : 75 : 60 : 20 kg NPK ZnSO4/ha did not show any significant improvement in grain yield. However, the yield attributes viz., spikes/m2, grains/spike, test weight and spike fertility ratio increased significantly upto 120 : 60 : 45 : 20 kg NPK ZnSO4/ha over control, 90 : 45 : 45, (with and with out ZnSO4) and 120 : 60: 45 kg NPK/ha but remained at a par with other levels of fertility tested in the experimentation. Most of the growth and developmental parameters in the study significantly increased upto the highest level of fertility management i.e. 150 : 75 : 75 : 40 kg/ha. Comparison of available NPK and Zn in soil after harvest of crop with the initial status under different treatments indicated the reduction in residual soil available nutrients at their lower level of application. However, an increase in available NPK in soil were noticed with the application of 150 : 75 : 60 and 150 : 75 : 75 kg NPK/ha with and without Zn level, while the status of Zn in soil was found positive with other primary nutrient under treatment 150 : 75 : 75: 20 and 150 : 75 : 75: 40 kg NPK ZnSO4/ha only. Wheat crop grown under the fertility treatment 150 : 75 : 60 : 20 kg NPK ZnSO4/ha recorded maximum net monetary return of Rs. 36,331/ha which was on an average just the double of all those treatments where nitrogen was applied @ 90 kg/ha.Keywords
