Cassia tora seeds were subjected to four different pre-treatments and different incubation temperatures. Seeds treated with conc. sulphuric acid were found to be best of the pretreatments. Increase in speed and capacity of seed germination was achieved by incubating seeds at higher temperature in comparison to lower temperatures.Keywords

Indian Forester, Vol 133, No 6 (2007), Pagination: 749-758Abstract
A study was undertaken to estimate the structure of variation in cone and seed traits of Pinus roxburghii through three-level nested (hierarchical) classification model. The populations studied constituted a continuous stretch of this species. Between-population variation for the cone and seed characteristics was found to be very small as it ranged from 0 per cent to 26 per cent, depending upon the trait. The remaining 74 per cent or more of the variation in these characters was due to the between-tree within-population and the within-tree components. The study showed that if seed collectors are interested in cones of greater weight or length, they should search for trees possessing such cone or seed characteristics within their own planting region, rather than trying to find specific populations for such characteristics outside their planting region, because much of the variation in these traits is accounted for by differences between trees, rather than between populations. Else, they should search for desired stands in distantly located populations or in populations separated by some geographic barrier.- Effect of Nitrogen and Phosphorous on the Biomass Production of Phyllanthus amarus at Nursery Stage

Phyllanthus amarus is an important medicinal plant commonly known as Bhumyamalaki, belongs to family Euphorbiaceae. In the nursery raised seedlings of P. amarus nitrogen and phosphorus treatments were applied as: T0 Control, T1, 30 kg N/ha,T2, 40 kg N/ha, T3, 50 kg N/ha, T4, 30 kg N +50 kg P/ha, T5, 40kgN +50kgP/ha,T6,50kgN +50kgP/ha. The best results were recorded in T4 (N30∗P50) treatments as compared to others. The plants treated with N30∗P50 had highest plant height, number of branches, collar diameter, fresh and dry weight of shoot andhighest biomass.Keywords

The effects of seasons and ischolar_maining hormone on air layering were investigated in Ficus krishnae and Ficus auriculata. Trials were conducted in three different seasons, viz. premonsoon, monsoon and post-monsoon using Indole Butyric Acid (IBA) ischolar_maining hormone (100, 300 and 500 ppm). Results revealed that IBA enhanced the ischolar_main initiation and induced ischolar_maining in a shorter duration. Air layering trials in pre-monsoon season under 500 ppm IBA treatment exhibited maximum ischolar_maining percentage followed by monsoon and post monsoon season.Keywords

Hippophae salicifolia D.Don is a deciduous tree species restricted to the Himalayan region. Seeds of H. salicifolia were collected from Uttarakhand State three provenances. Experiments were conducted in order to investigate different temperatures and lights response index in germination behavior of H. salicifolia seeds. The highest mean germination was obtained at 25°C. Therefore , it is recommended that ±25°C can be considered optimum temperature for its seed germination under controlled conditions. The light study revealed that maximum germination percentagewas found in red light followed by yellow light and minimum germination observed in green light. Provenance of Chamoli was the best as compared to Uttarkashi and Pithoragarh.Keywords

The aim of this paper is to extend and generalize the theory of fixed point to theory of intuitionistic fuzzy fixed point. We prove common fixed point theorems for R-weakly commuting maps employing common property (E.A) in intuitionistic fuzzy metric space via implicit relations which are viable, productive and powerful tool in finding the existence of common fixed point. Our results unify and generalize various known results to more general class of noncompatible maps.Keywords

The study was conducted in selected villages (1%) of Varanasi district of Eastern plain region of Uttar Pradesh in India during the year 2018 to record the crop combinations with tree species and their stratified arrangement to identify agroforestry practices. The socio-economic studies based on general village profile, land holding, land use pattern and tree species planting pattern were performed in 12 villages representing eight blocks to collect the data with structured questionnaire and participatory rural appraisal (PRA) tools. The results demonstrated that a total of nine different agroforestry practices, silvi-horticulture, agrisilviculture, agri-horticulture, aqua-silviculture, agri-silvi-horticulture, agri-silvi-pastoral, silvi-pastoral, silvi-medicinal and homestead existed in different villages. Out of different categories, timber, fruits, medicinal, agriculture, flower and other plant species were recorded. It was recorded that out of existing agroforestry practices, scattered near farms and around homestead was found most common (about 47.0 %). The benefits from agro forestry practices in the villages was also assessed and ranked in their order of preferences in respective blocks of district. The different benefits as shade, fruits/vegetables, timber, protection, firewood, soil erosion, medicinal and fodder were scored from 1 to 8. The status of tree plantation in different area was also studied and found trees of mango were most abundant (33.1%), it was noticed that old mango trees were of deshi variety but new trees were mostly of kalmi variety for fruits. The Neem trees were recorded (25.5 %) followed by shisham (9.5 %) and teak (14.0 %). It was concluded from the results that status of agro forestry in the studied zonal area of the region is in developing stage and needs to be improved by imparting technical knowledge about planting material, methods and sale of end produces of trees to the farmers and tree growers.Keywords

We studied the growth performance of fast-growing trees, viz. Eucalyptus spp., Casuarina equisetifolia, Gmelina arborea and Melia dubia in high-density plantation in Prayagraj, Uttar Pradesh, India, with different spacings, viz. 1×1 m, 1.2×1.2 m and 1.5×1.5 m. The experiment was established in July 2019 and data were recorded for the first and second year. In the second year maximum height increment was found in T1 (Eucalyptus 1×1 m; 3.42 m) followed by T5 (Eucalyptus 1.2×1.2 m; 3.40 m) and minimum in T2 (Casuarina 1×1 m; 1.39 m), whereas maximum girth increment was found in T1 (Eucalyptus 1×1 m; 12.43 cm) followed by T9 (Eucalyptus 1.5×1.5 m; 10.66 cm) and minimum in T6 (Casuarina 1.2×1.2 m; 6.46 cm). Maximum biomass in the first year was found in T6 (Casuarina 1.2×1.2 m; 15.51 t ha–1), followed by T1 (Eucalyptus 1×1 m; 14.71 t ha–1) and minimum in T12 (Melia 1.5×1.5 m; 0.66 t ha–1), whereas in the second year maximum biomass was found in T1 (Eucalyptus 1×1 m; 202.72 t ha–1), followed by T5 (Eucalyptus 1.2×1.2 m; 98.81 t ha–1) and minimum in T12 (Melia 1.5×1.5 m; 17.34 t ha–1). Carbon stock and carbon sequestration were maximum in the first year in T6 (Casuarina 1.2×1.2 m) followed by T1 (Eucalyptus 1×1 m) and minimum in Melia (1.5×1.5 m), with values of 7.75, 7.35, 0.33 t ha–1, and 28.42, 26.96, 1.21 t ha–1 respectively. Whereas in the second year maximum was found in T1 (Eucalyptus 1×1 m) followed by T5 (Eucalyptus 1.2×1.2 m) and minimum in T12 (Melia 1.5×1.5 m), with values of 101.36, 49.41, 8.67 t ha–1, and 371.59, 181.12 and 31.78 t ha–1 respectively. Maximum productivity was found in T1 (Eucalyptus 1×1 m; 188.01 t ha–1) followed by T5 (Eucalyptus 1.2×1.2 m; 89.88 t ha–1) and minimum in T12 (Melia 1.5×1.5 m; 16.68 t ha–1).Keywords
