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.

    Development of interspecific hybrids between Indian mustard (Brassica juncea Coss. & czern) and white mustard (Brassica alba Moench) through embryo rescue
    (CCSHAU, 2010) Asha Rani; Yadav, R.C.
    Wide hybridization is an important method of incorporation of desirable character. The present study was undertaken to develop an interspecific hybrids between B. juncea cv. RH30, cv. RH8812 and B. alba to incorporate the Alternaria blight resistant character from B. alba to B. juncea. Ovules were excised from siliqua and cultured on seven different media supplemented with different growth regulators. In cv.RH30 X B. alba,the hybrid siliquae were 1.2 to 3 cm in length whereas in case of parent plants of cv. RH30, siliquae length was between 4.1 to 4.5 cm. In cv. RH8812 X B. alba, the hybrid siliquae ranged from 2.8 to 3.4 cm in length while in parent plants of cv. RH8812, the siliquae length was between 4.9 to 5.7 cm. In cross of RH30 X B. alba and RH8812 X B. alba, 48% and 39% pod setting was observed respectively. In case of cv. RH30 X B. alba, highest percent response for ovule germination (79.46%) was observed on MS medium supplemented with kinetin (2.5mg/l) and CH (0.5g/l). In case of Brassica juncea cv. RH8812 X B. alba, highest response (45.63%) of ovule germination was on MS + BAP (2.5 mg/l) + CH (0.5mg/l). Six rooting media were tried for root formation in regenerated shoots. Maximum rooting response was 100% on MS medium supplemented with IAA (0.5mg/l) in both the hybrids. The regenerated hybrid plants were transferred to a mixture of sand: soil in 1:1 ratio in pots and 80 percent hybrid plants survived in the soil.

    Biogas production from vegetable foliage as supplement to cattle dung
    (CCSHAU, 2013) Asha Rani; Anand, R.C.
    The basic problem we face today is that the earth's natural resources of energy are being depleted at a most alarming rate but our conventional energy resources are limited and already have been over exploited. Motivated by the need to meet the ever-increasing energy demand and sustainability consciousness, many Governments have promoted renewable energy technologies such as biogas. Biogas (a mixture of approximately 60% methane and 40% carbon dioxide) is a well-established fuel that can supplement as an energy source for cooking and lighting in developing countries. Most of the biogas plants in India are being operated with diluted cattle dung slurry at 7-8% total solid concentration. Due to constraints in these conventional biogas systems, solid state fermentation system operated at about 15% total solid concentration using cattle dung as substrate has come into existence. Availability of animal waste is one of the major problem for successful operation of biogas digesters. So researchers are looking towards other alternative substrates. Raw vegetables wastes are used to produce biogas by anaerobic digestion process from a long time because in principle, it has high energy potential and enormous quantity of vegetable wastes are dumped daily in municipal and urban areas which needs to be processed to minimize environmental pollution. Anaerobic digestion of vegetable foliage alone is inefficient because the nutrients and minerals required for bacterial growth are not present at sufficient level. To reduce environmental pollution and to supply sufficient biogas production necessitated this study, with the ultimate goal of assessing the effect of co-digestion of cattle dung and vegetable foliage on biogas production. Vegetable foliage was mixed with cattle dung @ 5, 10, 15 and 20 % on wet weight basis and digested in batch as well as semi continuous mode for seven weeks. The maximum biogas production (34.1 l/kg) and TS degradation (21.9%) was obtained on supplementation of 20% vegetable foliage to cattle dung in batch digestion. The N, P and K content of effluent were1.78, 0.56 and 1.52%, respectively. Under semi-continuous mode with digestion period of seven weeks, the maximum biogas production (45.2 l/kg) was found at 20% supplementation level of vegetable foliage to cattle dung. This indicates that 20% vegetable foliage can be supplemented safely to cattle dung for higher biogas production. However, under semi-continuous conditions, increase in biogas production was found upto four weeks only and it decreased after wards. The solid conversion efficiency of TS (0.304 l/g) and VS (0.357 l/g) was also highest in digester-5 as compared to digesters 1, 2, 3, and 4, respectively during four weeks and decreased in subsequent weeks. This suggest that for higher biogas production, the supplementation of vegetable foliage can be made upto four weeks only in semi-continuous digestion and after four weeks, fresh vegetable foliage has to be added to get higher amount of biogas production. Further, it can be interprated that the supplementation of vegetable foliage more than 20 % may increase the biogas production further but it needs to be tested.
