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.

    Integrated management of rice root-knot nematode, Meloidogyne graminicola in transplanted rice
    (CCSHAU, 2019) Vinod Kumar; Verma, K.K.
    Studies were carried out on integrated management of rice root-knot nematode, Meloidogyne graminicola in transplanted rice involving three pronged strategies i.e. laboratory, screen house and farmer‟s field conditions. Under laboratory conditions, all the substances (rhizobacteria, aqueous extract of phytotherapeutic substances and chemicals) inhibited larval hatch and mortality of M. graminicola at all dilutions i.e. 1:5, 1:10, 1:20, 1:40 and 1:80 and at each interval of exposure period i.e. 1, 2, 4, 6 and 8 days. Maximum and significantly higher hatching inhibition and larval mortality was found, where eggs and larvae of M. graminicola were exposed to the chemicals i.e. carbosulfan followed by cartap hydrochloride. Among the rhizobacterial strains and plant extracts, the maximum hatching inhibition and larval mortality was observed in Azotobactor chroococcum (HT-54) which is statistically at par with aqueous extracts of Azadirachta indica. However, A. chroococcum HT 54, A. indica and carbosulfan gave maximum inhibition of egg hatch and mortalty at 1:5 and 1:10 dilutions irrespective of period of exposure. Under nursery conditions, neem cake @ 50g/pot+P. fluorescens @ 50 g/pot treatments had significantly highest seedling growth of rice as compared to untreated check. It was found that integration of neem cake @ 50g/pot with P. fluorescens @ 50 g/pot (nursery) significantly reduced the nematode reproduction and multiplication. Upon transplanting of treated nursery into already treated soil under screen house conditions, it was found that integration of treated nursery (neem cake @ 50g/pot+P. fluorescens @ 50 g/pot) with neem cake @ 25g/pot+P. fluorescens @ 25 g/pot) had significantly highest plant growth parameters and minimum nematode reproduction and multiplication under screen house conditions. Similarly, reproduction factor was found minimum in treated nursery (neem cake @ 50g/pot+P. fluorescens @ 50 g/pot) with neem cake @ 25g/pot+P. fluorescens @ 25 g/pot. In main field experiment, where treated nursery treatments were integrated with main field treatments, significantly highest and maximum yield was obtained in combination of treated nursery (neem cake @ 50g/pot+P. fluorescens @ 50 g/pot) with deep summer ploughing. It was observed that combination of treated nursery (neem cake @ 50g/pot+P. fluorescens @ 50 g/pot) with+deep summer ploughing significantly reduced the nematode reproduction and multiplication. Similarly, it was observed that highest rice grain yield was recorded when treated seedlings were transplanted in combination of deep summer ploughing. Such studies will lead us to a scenario where management of M. graminicola would be possible by integration of ecofriendly, economic and effective components starting from laboratory to nursery and to the end point of rice cultivation in the main field.

    Effect of integrated nutrient management on growth, seed yield and quality of coriander (Coriandrum sativum L.)
    (CCSHAU, 2019) Vinod Kumar; Tehlan, S.K.
    The present investigation was carried out at Vegetable Research Farm and in the laboratories of the Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar to assess the effect of integrated nutrient management on seed yield, quality and relative storability in coriander. The material comprised of newly developed coriander variety “Hisar Bhoomit” which was grown with eighteen treatment combinations of organic manures, inorganic fertilizers and biofertilizers. All the treatment combinations were evaluated for different growth, seed yield, quality, and storability parameters. Experimental results revealed that the application of 100 per cent recommended dose of nitrogen (60 kg per ha) through inorganic sources (T1) along with biofertilizers (Azotobacter and PSB) recorded superior performance over other treatments with significantly higher values for all the growth and yield attributes viz, Plant height, number of branches per plant, number of umbellets per umbel, number of seeds per umbel , number of seeds per umbellet , seed yield per plant (g), seed yield (kg/ha), biological yield (kg/ha) and harvest index (%). The net returns and benefit cost ratio was also found highest in this treatment during both the years of experimentation. However, the seed inoculation with azotobacter and phosphate solubilizing bacteria (PSB) along with recommended dose of nitrogen through vermicompost (T5) recorded significantly higher test weight (g), standard germination (%), seedling length (cm), seedling dry weight (mg), vigour index –I, vigour index –II, dehydrogenase activity (OD g-1 ml-1), superoxidase dismutase (mg protein-1 min-1), field emergence index, seedling establishment (%) and minimum electrical conductivity (μ S cm-1 g-1). The same treatment also recorded significantly higher relative storability as adjudged by standard germination, seedling length, seedling dry weight, vigour index –I, vigour index –II and minimum electrical conductivity (696.92 μ S cm-1 g-1) after accelerated ageing of seed for 24, 48, 72, 96 and 120 hours at 40±1⁰C at 100% relative humidity.
