    Comparative performance of different varieties of soybean (Glycine max L. Merrill) under poplar based agroforestry system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Joshi, Harshita; Rajput, P.R.
    An experiment was conducted during kharif season of 2003 at Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of growth conditions on productivity and quality of different varieties of soybean (Glycine max L. Merrill). The experiment was laid out in split plot design with two growth conditions (under poplar and sole soybean) as main plots and 12 verities of soybean (PK 262, PK 327, PK 416, PK 472, PK 1029, PK 564, PS 1024, PS 1042, PS 1092, PS 1241, Shilajeet and JS 335) as sub plots with three replications. Germination count, root length, root dry weight, plant dry weight, chlorophyll content and leaf area index were found to be higher in open system (sole soybean) as compared to agroforestry system at all the growth stages. Whereas plant height, number of trifoliate leaves, number of root nodules and nodules dry weight was found to be higher under poplar plantation as compared to open system at all the growth stages. Variety PS 1241 showed maximum germination and plant dry weight (above ground portion) at harvest. Whereas, variety PS 1042 showed maximum plant height, number of trifoliate leaves, root length, number of root nodules and root dry weight nodules dry weight at all the growth stages. Variety PK 472 showed highest chlorophyll content and leaf area index. Significantly higher values of yield and yield attributes were recorded in open systems as compared to under poplar plantation. Higher values of yield attributes were obtained by variety PS 1241. Maximum grain yield was produced by variety PS 1241 and Variety PS 1092 yielded maximum biological and straw yield. Higher values of nitrogen content in grain and straw, protein content and oil content in grain were obtained under poplar plantation as compared to open. Protein content in grain was significant higher in PK 1029, oil content in grain was maximum in PK 472 and nitrogen content in grain and straw was obtained maximum in variety PK1029.

    Bio and synthetic fertilization of mungbean (Vigna radiata L. Wilczek) cultivars in poplar based agroforestry system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-01) Pandey, Apurv; Tewari, Salil K.
    A field experiment was conducted during kharif season of 2003 at Agroforestry Research area of Horticulture Research Centre of G.B.P.U.A&T, Pantnagar to evaluate the growth and yield of mungbean cultivars under poplar and open and effect of Rhizobium inoculation anf fertilizer incorporation on yield and yield attributes of mungbean under poplar and open. The experiment was laid out in Split-split plot design with three replications. Two growth conditions viz. under poplar and open was taken in main plot, three mungbean genotypes namely Pusa 105, Pusa 9531 and Pant mung 2 were taken in sub-plot and four fertilizer treatments viz. no addition, recommended fertilizer dose (20:60:40 kg NPK/ha) incorporation, sole Rhizobium inoculated seeds and recommended fertilizer dose (20:60:40 kg NPK/ha) incorporation along with Rhizobium inoculation seeds were applied. Germination count, root length, number of root nodules, root dry weight, nodules dry weight, number of trifoliate leaves and days taken to flowering were found significantly higher under poplar. Number of primary branches, dry matter accumulation, Chlorophyll content, Leaf Area Index and Yield contributing characters was found maximum in open condition which was significantly more over agroforestry. In different genotypes of mungbean, Pusa 9531 produced maximum grain yield than Pusa 105 and Pant mung 2. Fertilizer treatment T4 (Fertilization along with Rhizobium inoculation) proved to significantly superior for growth, development and Yield and yield attributes over other fertilizer treatments.

    Clonal evaluation of poplar (Populus deltoides Bartr.) at nursery stage
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-01) Garg, Anshul; Tewari, Salil K.
    Poplar (Populus deltoides Bartr.) is one of the most important agroforestry tree species in the states of northern India. The present investigation was conducted on two set of prominating poplar clone having thirteen and forty two treatments planted in the new site of Agroforestry Research Centre at Haldi, G.B. Pant University of Agriculture and Technology, Pantnagar. The objectives of the study were to study the variability for different growth characteristics and to identify the prominent clones through morphologica markers. Observations were recorded on five competitive trees for height, diameter, and number of leaves, leaf pigmentations and leaf colour and were subjected to appropriate analysis. Significant genotypic variability was observed for all the characters. Wide range of mean value was observed. In the month of November, significant and positive correlation was observed between plant height and diameter, but number of leaves were not found significant in the month of November when it interact with other months except the month of October. Monthly increment was also observed in height, diameter and number of leaves. Highest increment for height, diameter and number of leaves were observed for set I in the month of September, March and June respectively and for set II, it was observed in November, September and June, respectively In the month of November, diameter and height, number of leaves and height and diameter and number of leaves were significant with most of the month. Morphological markers showed that different clones posses’ peculiar morphological distinctions.

    Early growth performance of different agroforestry tree species
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Goswami, Sandhya; Tewari, Salil K.
    The present investigation was conducted on two sets of multipurpose tree species having fifteen and twenty- eight tree species as a treatment at Agroforestry Research Centre, Haldi, G. B. Pant University of Agriculture and Technology, Pantnagar, (Udham Singh Nagar) during December 2003 to May 2004. Experiment was conducted in Randomized block design with five replications. Single plant data were recorded in each treatment on growth characters viz. height, collar diameter, clear bole length, crown length, crown width, number of branches and chlorophyll content at 30 days interval. Nitrogen and Protein content were taken in the last month of investigation. Variability in growth performance was observed for different tree species. Cassia siamea, Acacia catechu, Tectona grandis, Anthocephalus chinensis for set I and Eucalyptus tereticornis, Bauhinia variegata, Kizelia pinnata, Calistemon lanceolatus showed superior growth from agroforestry point of view. Higher nitrogen and Protein content obtained in Albizia lebbeck, Cassia simaea etc. in set I and Cinnamomum zeylanicum, Bauhinia variegata etc. in set II. The correlation analysis showed mutual relationship of growth characters with each other. During April and May height and collar diameter showed significant growth while during December and March significant growth observed in all the growth characters.
