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.

    Comparative effect of neonicotinoid insecticides toxicity on antioxidant defense system of Eisenia fetida and its consecutive effect on Common carp, Cyprinus carpio
    (CCSHAU, Hisar, 2020-11) Gill, Parveen; Gupta, R.K.
    The present has designed to evaluate the toxic effects of neonicotinoide insecticides viz. acetamiprid and imidacloprid on standard test species that is earthworm, Eisenia fetida and fish Cyprinus carpio with regard to haematology and histological parameters. Neonicotinoides are the most prominent class of pesticides in all over world. Filter paper contact toxicity test was used to determine LC50 of acetamiprid and imidacloprid against Eisenia fetida that was 0.165μg/cm2 and 0.195μl/cm2 respectively. The morphological, behavioural alterations and antioxidant defence response in the earthworm Eisenia fetida exposed to neonicotinoides (acetamiprid and imidacloprid) insecticides were investigated and affect the following preclittelar bulging, body constriction, blackening of body, segments swelling, oozing out of coelomic fluid, body constrictions, cuticle rupture and oozing out of fluid from the body are major detrimental effects noticed. Antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and Peroxidase (POD) activities were used as useful biomarkers to evaluate the effect of these two pesticides. The SOD, CAT and POD activities were significantly increased with an increase in the doses of acetamiprid and imidacloprid at 24 hr to 48 hr of exposure time. During 28th day’s exposure of Cyprinus carpio to various doses of acetamiprid and imidacloprid have showed various detrimental effects on their organs. Haematological parameters of fish are very important for assessment of fish physiological status affected by pesticides and Hb, PCV, RBC and MCV content of fish has decreased, when fish fed on earthworms treated with doses of acetamiprid and imidacloprid whereas WBC, MCH and MCHC increased. Histopathology study of fish provides various information regarding anatomical as well as morphological parameters of fish and untreated fish showed normal feature in all organs (gills, liver, kidney, intestine spleen, heart andskeleton muscle) whereas treated fish with pesticides showed various kinds of injuries to the organs and intensity of injuries in organs increased with increased doses of pesticides.

    Growth, reproduction and vermicomposting efficacy of earthworm (Eisenia foetida)
    (CCSHAU, 2015) Gill, Parveen; Dharambir Singh
    Vermicomposting is a simple biotechnological process of composting (organic waste management), in which certain species of earthworms are used to enhance the process of organic waste management and produce a better end product. It is a mesophilic process, utilizing microorganisms and earthworms that are active at 10–32°C. The resulting vermicompost has been shown to have several positive impacts on plant growth and health. Eisenia foetida is one of the earthworm species utilized for organic waste management. This organic bio fertilizer is therefore increasingly considered in agriculture and horticulture as a promising alternative to inorganic fertilizers. In present study, vermicompost samples were prepared from different organic wastes like cow dung, cow dung + Parthenium, cow dung + mixture of different Weeds and cow dung + Kitchen waste with a time interval at 0,30,60 and 90 days. The changes in the micronutrients like nitrogen, potassium, phosphorus, organic carbon, and C:N ratio was observed. In different organic wastes different changes in nutrients were found. It was observed that the nitrogen, potassium and phosphorous content in all the used wastes substrates increased but these were found more in kitchen waste product in all of them. The C:N ratio level decreased in all of them and carbon level is also declined. In present studies the direct and indirect effects of vermicompost on plant growth, as well as variability in the plant responses, were examined in pot experiment with tomato and brinjal. Total five growth and yield parameters were recorded viz. height of plants, diameter of main stem, dry weight of whole plant (except fruit and roots), number of fruits per plant and total weight of fruits/seeds per plant and better results were found in vermicompost as compare to other fertilizer. Results from present study provide a promising opportunity, which after some further studies and observations can be commercially utilized.
