Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Studies on the interaction of carbosulfan as seed treatment and fertilizers against root-knot nematode (Meloidogye javanica) in chickpea.
    (CCSHAU, 2004) Raheja, Sandeep; Gupta, D.C
    Studies on the interaction of carbosulfan as seed treatment with both the methods i. e. seed dressing and seed dipping and fertilizers against root-knot nematode (M. javanica) in chickpea showed that the carbosulfan as seed treatment in the presence of NPK performed well. Among various doses of carbosulfan as seed treatment, carbosulfan 25 SD @ 3 per cent a. i. w/w as seed dressing significantly proved better as compared to carbosulfan 25 EC @ 0.1 per cent a. i. v/v as seed dipping. NPK at recommended dose significantly improved plant growth characteristics and reduced the number of galls as compared to check. Maximum plant growth characteristics and reduction in number of galls was observed in sandy loam soil as compared to sandy soil. Various interactions of fertilizers, chemicals and soil types were also found significant.

    Studies on the prevalence and management of rice root knot nematode, meloidogyne graminicola golden and birchfield, 1965
    (CCSHAU, 2008) Ram Sharan; Nandal, S.N.
    An abstract of thesis submitted to the Chaudhary Charan Singh Haryana Agricultural University in the partial fulfillment of the requirements for the degree of M. Sc. (Ag.) in Nematology). An extensive survey was conducted for the prevalence of Meloidogyne graminicola in the Karnal, Panipat and Sonepat districts of Haryana. The results revealed that all the rice nurseries of these districts were infected with M. graminicola. Maximum occurrence (71.4%) was found in Sonepat district, while in Panipat and Karnal districts 50% and 34.2% rice nurseries, respectively were found infected. An intensive survey was conducted in the rice nurseries of fourteen villages of Kharkhauda block of Sonepat district for the prevalence of M. graminicola. All the rice nurseries in these villages were found infected with this nematode. Frequency of occurrence was recorded to be 62.5% of this nematode in Kharkhauda block. The effect of rhizobacteria, namely Azotobacter chroococcum (103, MSX-9, HT-54 and BNR-6), Gluconacetobacter diazotrophicus (CO 99-70, 35-47 and 760-50), Bacillus spp. (91 and 65), Pseudomonas fluorescens and P. maltophila was studied in rice in naturally infested soil with M. graminicola under green house conditions. The results showed that all the rhizobacterial strains except (A. chroococcum strain 103) significantly increased the plant height and weight and reduced the number of galls/plant and nematode over untreated check. Maximum plant height (6.75cm) was recorded in G. diazotrophicus strain 760-50 and Bacillus spp. 91. Similarly, maximum plant weight 0.83g and 0.93g was recorded in both treatments, respectively. However, maximum reduction of nematode population (0.5 and 0.6 times) was observed in G. diazotrophicus strain 760-50 and A. chroococcum strain BNR-6, respectively over untreated check (1.5). The effect of oil cakes of neem and mustard, and leaves of neem and calotropis each @ 1% and 2% w/w as soil application was studied on rice infected with M. graminicola in pots. The results showed that all treatments significantly increased the plant height, weight and reduced number of galls/plant and nematode population of M. graminicola over untreated check except neem cake @ 1% dose. Amongst various plant products, maximum height (9.75 cm) and weight (1.82g) was recorded in mustard cake @ 2%. Similarly, minimum gall numbers (3.25/plant) and maximum reduction (0.4 times) in nematode multiplication was recorded in mustard cake @ 2% dose.

    Studies on some ecological factors affecting the multiplication, virulence and survival of entomopathogenic nematodes, steinernema abbasi, elawad et al., 1997 and heterorhabditis indica, poinar et al., 1992
    (CCSHAU, 2008) Sunanda B.S.; Nandal, S.N.
    Present study was carried out with the objective to investigate the impact of some ecological factors affecting the multiplication, virulence and survival of entomopathogenic nematodes, Steinerema abbasi and Heterorhabditis indica. The studies on effect of temperature on life cycle of IJs the result revealed that of S. abbasi and H. indica were able to penetrate at temperatures ranging from 20-30ºC. Highest number of IJs penetrated was observed at 25ºC after 24-48 hrs and IJs of S. abbasi and H. indica emerged from Galleria mellonella larvae at 20-30ºC. The studies further revealed that the time (days) taken for emergence of both the nematode species was least at 20ºC and At 25ºC highest number of IJs of S. abbasi (138.89 IJs) and H. indica (137.16 IJs) were emerged. Duration of first and second generation of IJs of S. abbasi was 3-4 days and 7-8 days respectively and for H. indica 3- and 6-10 days respectively. Number of male and female of amphimictic generation was 10.9 : 123.9 and 12.5 : 132.5 observed at 25ºC, S. abbasi and H. indica respectively. Sex ratio (male : female) was 1 : 11.3 – 1 : 14.9 and 1 : 10.6 – 1 : 14.7 S. abbasi and H. indica observed. Observation on longevity were recorded at different temperatures viz. 10, 20, 30 and 40ºC and at different interval viz. 15, 30, 45, 60, 75 and 90 days. At 30ºC highest survival of IJs (97.76%) and (88.09%) Steinernema abbasi and H. indica respectively. Longevity IJs at 10ºC and 40ºC was least in both species of nematodes. The studies on effect of aeration on survival IJs the revealed that survival of IJ in aerated condition and non aerated condition was 95.2 and 79.8% observed respectively, but highest survival of IJs in 5000 (IJs/ml) than the 10000 IJs/ml in both species of nematodes. Among nematodes, H. indica survival rate highest in aerated condition then S. abbasi but S. abbasi survival rate highest rate in non-aerated condition than H. indica. The studies on effect of antidesccants on survival of IJs revealed that the maximum survival of IJs was obtained in liquid paraffin in both the nematode species highest survival in (4%) concentration. Lower concentration (1%) of Liquid paraffin, Glycerol and Tween 80 had increased the survival of IJs of both the nematode species. Survival of IJs decreased as time of exposure increased from 7-30 days. The studies on effect of UV light and survival of IJs revealed that addition of optical brighteners, PABA and CRP enhanced the tolerance of both the nematode species to UV light. Among two UV light protectants, Para amino benzoic acid (PABA) provided excellent protection to IJs than Congored Powder (CRP). Among the different concentration of these optical brighteners 0.5% of both PABA and CRP observed highest survival upto 60 minutes exposure to UV light. Among nematodes H. indica was more tolerable to UV light then S. abassi.
