    Vegetative propagation of eucalyptus tereticornis Sm. (Mysore gum) through stem cutting
    (CCSHAU, 2006) Rajpal; Kaushik, J.C.
    The present study on vegetative propagation was carried out during May-June 2005 in mist chamber of Centre for research and application in plant tissue culture, Chaudhary Charan Singh Haryana Agricultural University, Hisar. In collaboration with Department of Forestry. The soft wood cuttings (< 0.5cm) and hard wood cuttings size of (>0.5cm) in diameter were collected in May 2005 from the coppicing shoots raised on stumps, for coppicing, the trees were felled in month of March. Saw was used to give a standing cut so that moisture does not accumulate on the cut portion. The stumps was prepared without harming the phloem and bark of wood. The growth regulators viz. IAA, IBA NAA, thiamine and their combination at 2000, 3000, 4000 ppm concentration level were tried. The medium taken was vermiculite in polythene bags. All the growth regulators tried were found to be better for sprouting, rooting and all growth parameters then control. In control there was no sprouting and rooting indicated that the necessity of application of regulators. The degree of success in term of sprouting and rooting, root length and root dry weight were significantly higher in IBA 3000 ppm concentration. On the other hand, stackling height, number of leaves and shoot dry weight were found to be higher in IAA 2000 ppm treatments. The effect of type of cuttings Indicated that the soft wood cuttings were found to be better in respect of all growth parameters over the hard wood cuttings. Higher concentration of growth regulators exhibited inhibitor effect on root shoot length root, shoot dry weight number of leaves and total Biomass. IBA 3000 ppm and there combination were found to be better for root parameter.

    Studies on reproductive biology and vegetative propagation in Jatropha curcas L.
    (CCSHAU, 2006) Aman Kumar; Dhillon, R. S.
    The present investigation on “Reproductive biology and vegetative propagation in Jatropha curcas L.” was carried out during 2004-2005. The studies on phenology, floral biology and breeding system were carried out on the plants growing in the campus of CCS Haryana Agricultural University, Hisar. The remaining part of the study was conducted by collecting one year old stem/branch cuttings during spring (February-March) and rainy (July-August) seasons. The cuttings were treated with different growth regulators viz. IAA, IBA, NAA and thiamine at 0, 250, 500, 1000, 1500 and 2000 ppm concentration levels for 16 hours and were raised in polythene bags filled with sand, soil and FYM in equal proportion and these poly bags were placed in nursery beds. Observations on sprouting and rooting parameters were recorded after 90 days of planting of cuttings. Defoliation started in first week of October and continued up to end of February, majority of which being completed by mid-February. Leaf primordia started appearing after first fortnight of March. The emerging leaves attained full size in about one month, although emergence of new leaves and their development continued up to end of December. It is monoecious plant i.e. male and female flowers are found separately in the same inflorescence. The male floral bud developed earlier than female ones. The male and female flower buds took 20 to 23 days and 23 to 25 days, respectively, to come to bloom. Maximum flower opening was noticed between 0700 to 0830 h in male flowers and 0730 to 0830 h in female flowers. The female flowers population resulted in sharp decrease with the fall in temperature during winter months and their ratio to male flowers became unfavourable. The flowering pattern showed a low rate initially during November end, gradually increasing to peak during December, followed by cessation from December end to mid-January. The number of days required from anthesis to fruit maturity ranged from 56 to 63 days. Maximum pollen viability (64.1%) was recorded at 1030 h. Dehiscence was observed one hour after anthesis. The receptivity of stigma started with flower opening and continued up to 72 hours after flower opening. The flower visitors included bees, ants, thrips and flies. They played major role in pollination through geitonogamy and xenogamy. Fruit set under natural pollination varied from 60.0 to 100.0 per cent, while 0.0 to 83.3 per cent under selfing with general mean of 34.4 per cent. The high natural fruit set recorded indicates that the plant is capable of producing fruit through geitonogamy and xenogamy. Such a breeding systems represents facultative xenogamy. Spring season was found best for clonal multiplication, even the untreated cuttings showed 100 per cent sprouting during this season. Maximum rooting per cent was recorded in cuttings treated with 2000 ppm IBA in spring as well as rainy season. The average number of roots per cutting and root length were recorded higher in spring season. In spring season, the maximum number of roots per cutting (72.5) and root length (23.6 cm) were recorded in 1500 ppm NAA and IAA treated cuttings, respectively.

    Performance of late sown wheat varieties intercropped with eucalypts
    (CCSHAU, 2006) Pradeep Kumar; Nandal, D.P.S.
    The present investigation was carried out at the research area of the Department of Agroforestry at CCS Haryana Agricultural University during the rabi season of 2002-03. The experiment consisting of four varieties viz., Sonak, Sonalika, PBW373 and WH291 and three distances from the tree line/border viz., 0.0-1.0 m, 1.0-2.0 m and 2.0-3.0 m was laid out in factorial randomized block design with three replications each for wheat sown under eucalypts and wheat alone. Growth and yield attributes and consequently grain and straw yields of wheat were significantly less under eucalypts than sole wheat. Among the late sown wheat varieties, PBW 373 was found most compatible with eucalypts. Whereas in control PBW 373 and Sonak varieties were at par with each other. The yield of wheat varieties increased significantly with increasing distance from the tree line in agroforestry. However, in control no such increase was observed. Economic analysis of the systems revealed that after considering the returns from eucalypts, agroforestry was found more beneficial than raising of sole wheat.

    Biomass Production and Nutrient Contents in 8-year old Poplar Plantation
    (CCSHAU, 2006) Satish Kumar; Ravi Kumar
    In order to study the “Biomass Production and Nutrient Contents in 8-year old Poplar Plantation” 8 years old popular plantations grown under 5x4 m, 10x2.5 m and 15x2.5 m spacing were selected. Seven trees in each spacing were felled for recording observations for biomass production and nutrient analysis. The total amount of biomass production was maximum in 5x4 m spacing, followed by 10x2.5 spacing and minimum in 15x2.5 m spacing. About 75 percent of biomass was contributed by stem only. The concentration of N, P and K was maximum in leaves at 15x2.5 m spacing and decreased with decrease in spacing. Secondary nutrients (Ca, Mg, S) also followed the similar trend. Their concentration was also maximum in leaves. Concentration of Zn, Fe, Cu and Mn was recorded maximum in 1.5x2.5 m spacing and decreased with increase in spacing. Zn and Cu concentration were maximum in leaves, while the concentration of Fe & Mn were higher in roots. The uptake of all nutrients analysed was maximum at 5 x4 m spacing and their major portion was accumulated in the stem in all the spacings. In soil concentration of available N, P, K, Ca, Mg, S & micronutrients were maximum at surface layer in all the spacing, which decreased with increase in sampling depth.
