    Vegetative propagation by nodal cuttings in Eucalyptus clones
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-09) Tewari, Neetu; Tiwari, Salil K.
    The present investigations entitled “Vegetative propagation by nodal cuttings in Eucalyptus clones” was carried out at new site of Agroforestry Research Centre (AFRC), Haldi, G. B. Pant University of Agriculture and Technology, Pantnagar during March to June 2009. The investigations were performed in two different experiments in Completely Randomised Design in mist chamber and Randomised Block Design in vegetative multiplication garden (VMG). In experiment I, eight different clones viz. K-25, K-43, G-22, AP-10, AP-7, K-23, K-14 and K-16 were studied for their growth behaviour in VMG and sprouting & rooting response under intermittent misting. The results revealed the significant variation in growth, sprouting and rooting behaviour of different Eucalyptus clones. The following order was observed for clonal growth behaviour in VMG - K-25> AP-10> G-22> K-23> K-16> K-43> AP-7> K-14. For rooting, the order was K-43> K-25> G-22> AP-7> K-23> K-16> K-14> AP- 10. While maximum sprouting was observed in K-16 followed by K-14, K-23, G-22, AP-7, AP-10, K-43 and K-25. In Experiment II, effect of clone, girth class and height on growth behaviour, sprouting and rooting response was studied in two different Eucalyptus clones viz. AP-7 and K-25. The experiment was conducted with four different girth class treatments (viz. 15-20 cm, 20-25 cm, 25-30 cm and 30-35 cm) and three different stump height treatments (viz. 30 cm, 45 cm and 60 cm). The trend of growth behaviour in VMG was found K-25> AP-7. Similar trend was observed for sprouting and rooting behaviour. Among different girth classes G2 was found to be optimum for enhanced coppice shoot production while for rooting of cuttings G4 was optimum girth class. Among different stump heights, 60 cm was found to be optimum for coppice shoot production in VMG while there was no significant effect of height on sprouting response. However, for rooting behaviour the trend was H1> H2> H3. The interaction effect of clone, girth class and height was found significant for growth behaviour in VMG while it was non-significant in rooting behaviour. Hence, it was concluded that, growth performance of K-25 and AP-10 was superior than rest clones after coppicing in vegetative multiplication garden. Further, K-43 and K-25 can be easily propagated by rooted cuttings while AP-10 was difficult to root. The optimum height for enhanced coppice shoot production was found 60 cm. Whereas, 30 cm stump height was best for obtaining maximum rooted cuttings. The optimum girth of coppiced tree was found to 20-25 cm for enhanced coppice shoot production. While the girth of 30-35 cm was found to be more suitable for better rooting of cuttings.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Joshi, Reena; Tewari, Salil Kumar
    The present investigation entitled “Studies on Macro and Micro Propagation in Bamboo” was carried out at new site of Agroforestry Research Centre, Haldi, Pantnagar during June 2006 to May 2007 and in tissue culture laboratory of the Agroforestry Section, College of Agriculture, G.B. Pant University of Agriculture and Technology, Pantnagar. Experiments were conducted to see the effect of age (one and two year old), growing condition (open intermittent misting and open no misting), position (basal, middle and top) in different seasons (June, August, October and March) on rooting and sprouting of culm cuttings of Bambusa balcooa and Dendrocalamus asper. The findings indicated that two year old culm cuttings collected from basal position in the intermittent misting condition gave best response in B. balcooa. In D. asper, one year old culm cuttings with above condition showed good results. The findings also indicated that rooting and shooting per cent of culm cuttings planted in different season showed response as March> June> August> October in both the species. For micropropagation nodal buds from one year old B. balcooa and D. asper were taken as ex-plant. In B. balcooa for sterilization 0.1% Tween-20 (5 min), (1.0% Bavistine (5 min), 0.1% Streptomycin (4 min), 70% Ethanol (5 min), 1.0% NaOCl (8 min) and 0.1% HgCl2 (3 min)), for bud break (3.0 ppm BAP+ 1.0 ppm GA+ 0.5 ppm Kinetin), for proliferation of bud (4.0 ppm BAP+ 0.5 ppm Kinetin) and in D. asper 0.1% Tween-20 (5 min), (1.0% Bavistine (4 min)+ 0.1% Streptomycin (3 min)+ 70% Ethanol (5 min)+ 1.0% NaOCl (10 min)+ 0.1% HgCl2 (5 min)) for sterilization, (3.0 ppm BAP, 0.5 ppm Kinetin+ 0.5 ppm GA) for bud break, (5.0ppm BAP+ 1.0 ppm) for proliferation of bud were found to be best for this investigation. In vitro rooting studied using different auxins; 3 ppm NAA+2.5 ppm IBA and 4 ppm+ 2 ppm IBA were found to be best for B. balcooa and D. asper respectively.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-08) Amit Kumar; Rajput, P.R.
    An experiment was conducted during Rabi season of 2005-2006 at Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to evaluate the various provenances of Jatropha intercropped with Lentil. The experiment was laid out in Randomized block design with 3 replications and consisting of 9 treatments including 8 different Jatropha provenances (Kaladungi, Halduchour, Gola, Kheda, Bailparao, Bilaspur, Pantnagar-1 and Pantnagar-2) intercropped with lentil along with control (lentil in open). Emergence per cent, plant height, dry matter accumulation, number of primary branches per plant, nodules number and biomass, yield and yield attributes (number of plants per 0.25 m2, number of pods per plant, number of grains per plant, number of grains per pod and grain weight per plant) were found higher in lentil in open system as compared to Jatropha based agroforestry system at all the growth stages. Lentil under Pantnagar-1 showed higher emergence per cent, number of primary branches per plant (at 90 DAS), nodule biomass (at 120 DAS) and all yield attributing characters. Significantly higher values of yield and yield attributes were recorded in open system as compared to under different Jatropha provenances. Higher value of biological yield and grain yield of lentil were obtained under Pantnagar-1. Higher value of number of seeds per plant, seed length, collar diameter, height and number of branches were recorded in Bailparao provenance whereas higher seed weight per plant was found in Gola provenance.

    An experiment was conducted during kharif season of 2004 at Agroforestry Research Centre of G.B. Pant University of Agric. & Tech., Pantnagar, U.S. Nagar, Uttaranchal to study the effect of agroforestry systems on productivity and quality of different varieties of soybean (Glycine max L. Merrill). The experiment was laid out in split plot design with two agroforestry system (Shisham and Teak based agroforestry system) and control as main plots and six varieties of soybean (PK 1042, PK 416, PK 1024, PK 1029, PK 1092 and PK 1241) as sub plots with three replications Germination count, plant height, number of trifoliate leaves were found to be higher in agroforestry system as compared to open system at all the growth stages. Whereas, above ground dry matter accumulation and leaf area index was found to highest under control as compared to agroforestry system. Variety PK 1241 showed maximum germination count, above ground dry matter accumulation, plant population, grains per pod and 1000-grain weight. Significantly higher values of yield and yield attributes were recorded in open systems as compared to Teak and Shisham based agroforestry system. Higher value of yield was produced by variety PK 1241. Maximum grain yield, biological yield and straw yield were produced by variety PK 1241. Higher value of nitrogen concentration in grain and straw, protein and oil content in grain were obtained under control as compared to agroforestry. Protein content in grain was significantly higher in PK 1024, oil content in grain was maximum in PK 1042 and nitrogen concentration in grain and straw was obtained maximum in variety PK 1029.

    Performance of various rabi pulses under varying poplar (Populus deltoides Bartr. ex. Marsh.) tree spacings in agrisilvicultural system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-08) Jayaswal, Sanjay Kumar; Bana, O.P.S.
    A field experiment was conducted during the rabi season of 2004-05 at AICRC on agroforestry site, Horticulture Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar to study the production potential of different crops under varying density of poplar in agrisilvicultural system. The soil of experimental site was clay loam (0-15cm) in texture, having range of organic carbon (0.42-0.62%), available nitrogen (192.2-265.8 kg/ha), available phosphorus (20.4-34.6 kg/ha), available potash (102.9-158.4 kg/ha) and soil pH (7.86-6.90). Treatments consisted of four tree spacings (control, 5m×8m, 5m×4m and 5m×2m)/densities (0, 250, 500 and 1000 trees/ha) as main plot and four pulse crops (pea, lentil, fababean and chickpea) as subplot. The experiment was laid out in Spilt Plot Design with four replication. Observations were recorded on growth and development at periodical intervals, yield and yield attributes and protein content in grains. The results indicated that growth and biomass parameters showed wide variations due to tree spacings, pulse crops and their interaction. Although, the maximum germination per cent, plant population, plant height, number of nodules and dry weight, number of primary branches and dry matter accumulation were recorded under control (sole crop) with varying degree of reductions under increase tree densities. The mean crop growth rate, leaf area index, and relative leaf growth rate were recorded to be better in sole crop, but the mean relative crop growth rate, net assimilation rate (during 60-80 days period) and protein content in grains had been better under poplar trees. The maximum biological, straw and grain yield of pulse crops recorded under control (sole crop), which decreased under various tree spacing/densities with varying magnitudes among crops. The grain yield of pulse crops was maximum under control, which decreased significantly with decreased tree spacings from control to 5m×8m/5m×4m and then to 5m×2m in pea and fababean from control to either 5m×8m, 5m×4m or 5m×2m in lentil and from control to either 5m×8m or 5m×4m then to 5m×2m in chickpea. Thus, it may be concluded that based on the relative losses in corps, chickpea and lentil may be preferred for inter planting with poplars. The reduction in yields under trees may be well compensated through volume increment in poplar trees.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Gairola, Yogesh; Rajput, P.R.
    An experiment was conducted during winter season of 2004-05 at Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of agroforestry tree specis (Dalbergia sissoo and Tectona grandis) and spacing on growth, development and seed production of important winter annual flowers (Babuna, Dimorphotheca, Tagetes and Paper flower). The experiment was laid out in split-split plot design with three main plot treatments (Dalbergia sissoo, Tectona grandis and Control), four sub plot treatments (Babuna, Dimorphotheca, Tagetes and Paper flower) and two sub-sub plot treatments (60 cm 30 cm and 60 cm 60 cm) with three replications. Different growth characters (Plant height, Number of leaves/plant and Plant spread) and Floral characters (Number of flower/plant, Flower size and Days taken to maturity) were found significantly higher under tree species shisham (Dalbergia sissoo). Among different flower species Babuna and Paper flower has given better results for different growth and floral characters. The higher values of growth characters were produced by wider spacing (60 cm 60 cm), while close spacing (60 cm 30 cm) produced higher value for floral characters in winter annual flowers. The highest seed yield (kg/ha) was produced by Babuna followed by Paper flower under Shisham with close spacing as compared to control and Teak.

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.
