    Seed Source Variation for Seed and Seedling Characters in Kair [Capparis decidua (Forsk.) Edgew.]
    (CCSHAU, 2006) Kalu Ram; Bangarwa, K. S.
    Seeds were collected from five randomly selected trees of Capparis decidua from each of two sites from Rajasthan (Hanumangarh, Bhadra) and Haryana (Sirsa, Hisar) provenances during September 2005. The seeds of all the twenty progenies arising from four provenances were used for provenance testing in nursery and seed storage up to six months. Fruit diameter ranged from 14.79 to 22.88 mm with a general mean of 17.83 mm. Variability for fruit diameter was comparatively higher in Hanumangarh and Sirsa. Analysis of variance showed the presence of significant variation among progenies for germination per cent, plant height and collar diameter, whereas significant variation among provenances were observed for plant height and collar diameter. Medium values of phenotypic coefficient of variation and little difference from genotypic coefficient of variation were observed for all the three characters, viz., germination per cent, plant height and collar diameter. Heritability estimates and genetic advance were also found high for all the characters under study. Progeny number 8 from Bhadra provenance was found overall best for all the three characters viz., germination per cent, plant height and collar diameter. Progeny number 6 from Bhadra was found significantly superior than general mean for plant height and collar diameter whereas progeny number 1 from Hanumangarh was found significantly superior than general mean for germination per cent and plant height. In general, the provenances like Hanumangarh and Bhadra were found superior for seedling characters. Standard germination of fresh seeds varied from 53.74 per cent in progeny no.17 from Hisar to 62.21 per cent in progeny no.1 from Hanumangarh with a mean of 59.08 per cent. The average germination per cent of fresh seed (59.08) was reduced to 44.87 per cent three months after storage and which was further reduced to 32.73 per cent six months after storage. The reduction in both vigour index-I and vigour index-II were observed higher than standard germination for all the progenies up to six months of storage.

    Vegetative propagation of Dalbergia sissoo (Roxb.) through stem cutting
    (CCSHAU, 2006) Praveen Kumar; Bimlendra Kumari
    The experiment was conducted in the nursery of the Department of Forestry in CCS, Haryana Agricultural University (India) during February and August season of 2003-04. The cuttings taken form 8 to 10 years old tree from three zones of canopy i.e. upper, middle and lower with thickness i.e. 0.5 cm to 1.0 cm diameter (thin) and 1.1 cm to 1.5 cm (thick). These cutting treated with different plant growth regulators viz. indole-3-butyric acid, indole-3-acetic acid, nepthalic acid at three concentration levels i.e. 1000 ppm, 500 ppm, 250 and combination of thiamine with 500 ppm of each growth regulator. The experiment was laid out in completely randomized design with three replication. The results revealed that cutting planted in February season gave better percentage of rooting (60.6%), number of roots per cutting (4.0), root length (12.0 cm) per cutting and weight of roots (0.37g) than August planted cuttings. All the roots characteristics obtained were better with thick cutting than thin cutting and canopy levels followed the trend of lower, middle and upper canopy i.e. cutting from the lower canopy gave best results. IBA 1000 ppm was most effective in sprouting (75.5%) and rooting (66.4%) of Dalbergia sissoo stem cutting. All the PGRs treatment gave significantly better results in both the season with all the canopy levels and with thick as well as thin cutting over control. From the studies, it was concluded that when the cutting of Dalbergia sissoo is taken from lower canopy with diameter 1.1-1.5 cm (thick) treated with indole-3-butyric acid 1000 ppm planted in February season gave the best results with respect to duration of sprouting, percentage of sprouting, number of leaves per cutting, number of roots per cutting, weight of root and shoot, percentage of rooting and rootshoot weight ratio and average length of root per cutting.

    Studies on seed germination and storability of Rohida
    (CCSHAU, 2008) Ravi Kant; Bimlendra Kumari
    The present investigation was carried out on Rohida seeds. The seed material was collected from four different seed sources viz., Churu, Ding Mandi, Jhumpa and Rajgarh. The present study was conducted during 2005-06 at nursery area of Department of Forestry and laboratories of Department of Seed Science and Technology and Department of Forestry CCS HAU, Hisar. The objective of investigation was: To evaluate different seed sources for seed viability, germination and seedling growth behavior; To determine the storability of Rohida seed. Various morphological characters of Rohida trees from four different geographical locations were recorded and seeds were collected from the selected trees. Seed quality parameters such as seed size (length and breadth), colour, test weight, germination percent (74 %), speed of germination (13.63 %), radicle (6.30 cm) and plumule length(5.30 cm), seedling dry weight (415.60 mg), dehydrogenase activity (1.40), electrical conductivity vigour index I and II were studied of freshly harvested seeds and then stored in ambient storage conditions. The seeds of all the four different places were aged artificially at various time (24, 48 and 72 h) and temperature (40±1oC) variables. Accelerated ageing of seeds for 24 h at 40±1oC produced a clear separation and provide better results. Then seeds of all the four different places were tested to study physiological basis for loss in viability. It was observed that standard germination, seedling length, dry weight, vigour index I, vigour index II and viability percentage was found maximum in Rajgarh seed source.

    Studies on breeding of Common carp (Cyprinus carpio Lin.) using modified breeding technique
    (CCSHAU, 2010) Verma, Nitin; Gupta, R.K.
    Common carp (Cyprinus carpio) is one among the earliest species to be cultured. Its maturation and breeding is affected by biotic and abiotic environmental conditions of water. Nutrition is known to have profound effect upon gonadal growth as well as larval development. Common carp breeding is still very traditional in India, including Haryana.Quantity of common carp seed which is available is needed to be most economic and technique should be such that the resources are utilized most efficiently to meet the demand of farmers and entrepreneurs. The field experiment was designed under four sets of pond with three replicates and one controlled experimental pond. Fish weight, length, gonad weight, Gonado somatic index and fecundity were estimated for observing maturity of fishes. The effect of nutritious feed and environmental conditions on fertilization, hatching and survival of larvae were also studied. In the field experiment wide range of seasonal fluctuations were observed in the following factors. Water temperature showed a range of 9-28.5°C throughout the experiment. There was not much fluctuation in all the experimental pools. Conductivity values for different experimental pools were different and minimum value was recorded during onset of winter season. The pH values were found to range between 5.2 -7.3. During initial stages the pH value were lower and showed a gradual increase in the later stages. The variation in DO values ranged from 4.2-7.28 mg/l in different experimental ponds. DO content increased with higher production of photosynthetic organisms. Free CO2 varied between 0.03-6 mg/l. On cloudy day maximum free CO2 content was found initially because of more concentration of phytoplankton. Pattern of changes in both carbonate and bicarbonate alkalinities in different experimental sets were more or less similar. The carbonate alkalinity was observed to show a reverse trend to that of free CO2. It ranged between 0-5.6 mg/l. Bicarbonate alkalinity ranged from 86 to 124 mg/l in all experimental pools during the experiment. The BOD was higher initially. The value ranged between 0.48-8.96 mg/l. Some fluctuation is found in Hardness ranged between 156-189.7 ppm. Plankton volume ranged between 0.015- 0.018 cc/l in different experimental sets. Highest plankton volume was recorded in 1st week of February. The Gross primary productivity value was found to be low during clouds and rain. Fertilization, hatching and fry produced were also observed and found to be highest in the hatchlings produced from 6:1 male to female ratio. The highest growth was observed in hatchlings that were fed on rice bran & mustard oil cake in 1:1@150% of initial body weight.

    Studies on growth potential, market trend and wood volume tables of poplar (Populus deltoides) grown in Haryana
    (CCSHAU, 2012) Doha, Amit Singh; Bangarwa, K. S.
    The present investigation entitled “Studies on growth potential, market trend and wood volume tables of poplar (Populus deltoides) grown in Haryana” was carried out in the Yamunanagar district of Haryana, India. One to 6 years old plantations of poplar (G 48) with spacing’s of 5×4 m, 4×4 m, 6×3 m were selected for recording data in order to find out growth potential (height and DBH). Current annual increment for basal diameter was observed highest in 5 × 4 m spacing during all the six years as well as on the overall basis. The current annual increment for total height were in increasing order up to 4th year in all the three spacing as well as on overall basis. The rate of growth for total height was in decreasing order from 4th year to 6th year in all the three spacing. Ninety one randomly selected trees were sampled to predict the weight and volume table for poplar tree. Four equations were fitted using linear and non linear regression techniques to predict the volume table. Two models (Schumacher and Hall and single-entry) were used to predict the green timber weight. Results were statistically and graphically analyzed. All equations had very good-fit statistics. The Schumacher and Hall model was selected to estimate the volume of standing poplar trees in Haryana. It is not always easy to measure total height of each standing tree, which is both time consuming and cumbersome. Therefore, regression equation of timber volume based on DBH alone was also worked out. Survey of Yamunanagar market was conducted to find out prices of four types of poplar wood pieces. Prices of all the four types of poplar wood pieces for the last four years were recorded from randomly selected ten poplar wood purchasing units. Market survey for poplar wood suggests increasing trend from 2004 for all the four categories (over, under, sokta and dandi). The increase in poplar wood price for the last 3 years was comparatively low.
