Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    BROWN LEAF SPOT DISEASE IN BIDI TOBACCO
    (AAU, Anand, 1983) Patel, Ravibhai Somabhai; Desai, M. V.
    The study conducted on brown leaf spot disease of bidi tobacco incited by Alternaria alternaria (Fries) Koieslar pertaining to different aspects revealed that under controlled condition, inoculation with cosidial suspension of A. alternata could cause the disease symptoms within 6 to 7 days and the fungus grew best on PDA out of seven different media tried. In a study on effect of temperature ranging from 20 to 30°C (with an important of 5°C) in all possible combinations with five pH levels ranging from 4.5 to 8.5 (with an improvement of one), the satisfactory growth and sporalation were secured at temperature ranging from 25 to 30°C and pH ranging from 4.5 to 8.5.

    DOWNY MILDEW OF ISABGUL (PLANTAGO OVATA FORSK)
    (AAU, Anand, 1984) PATEL, JIVANBHAI GOBARBHAI; DESAI, M. V.
    Isabgul (plantago ovata Forsk) is an important medicinal crop of high export potential for our country, 1 The crop is attacked mainly by damping-off, wilt, downy, mildew, leaf blight and powery mildew. Among the diseases, downy mildew (peronospora plantaginis) is a serious one causing considerable damage to the crop. Following aspects of the disease were studied: (1) histopathology and morphology of the fungus, (ii) meteorological parameters in development of disease, (iii) phytochemical changes brought by disease and (iv) management of disease through cultural , chemical and resistance of Isabgul cultures/Varieties to downy mildew fungus. The results revealed that the fungus penetrates through stomata which grows intercellularly in host tissues. Remification by the fungus lead to tissue necrosis and death of plant. The sporangia are borne on sterigmata of the dichotomously branched sporangiophore. The sporangia germinate by germ tube and not by zoospores. The hypha is 6.25 to 12.50 μ thicks sterigmata are 4.25 - 12.50 x 4.0 - 4.20 μ and sporangia are 32.00 - 44.00 x 17.00 - 25.00μ. Effect of different temperatures (5 to 40°c with an increment of 5°c) studied in vitro revealed that 20°c is optimum for sporanglal germination. Under field conditions, the temperature around 20°c and relative humidity around 89 per cent favour maximum sporanglal germination between 2 a.m. and 8 a.m. and 8 p.m. and 10 p.m. The parameters during crop growth period help in development of severity of disease. Maximum disease under these conditions are observed between 75 and 95 days after sowing. The regression correlation for sporanglal germination is negative with temperature and positive with relative humidity. Biochemical studies of leaves collected from healthy and diseased plants revealed reduction in chlorophyll content by 57.71 and phenolics by 52.01 per cent due to infection by P. plantaginis. Moisture and total ash contents are also reduced in leaves of diseased plants.
