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.

    ALTERNARIA BLIGHT OF MUSTARD AND ITS MANAGEMENT
    (AAU, Anand, 2004) CHAUDHARY, MADHAV RAMJIBHAI; Patel, S. T.
    Indian mustard [Brassica juncea (Linn.) Czem and Coss], an important oilseed crop, ranks second next to groundnut in India. It yields valuable edible oil and is rich from nutritional point of view. Altemaria blight, caused by four species of Alternaria viz., A. hrassicae, A. hrassicicola, A. raphani and A. alternata, is an important disease . of cruciferous crops in India. Investigations were carried out to study effective technique for detection of pathogen from seeds, location of pathogen in seed, varietal response in respect of seed-borne nature of the pathogen as well as in vitro and in vivo evaluation of phytoextracts, fungicides and bioagent(s) against this disease. The pathogenic isolate of Alternaria alternata showed faster growth, produced greenish black to almost black colonies containing ovoid to oblong septate conidia measuring 21 to 56 X 10.5 to 17.5 µm. Among the three different methods employed for detection of A. alternata from seeds of mustard (cv. Varuna), SBM proved to be more effective than APM and deep freeze method. The component plating technique revealed the pathogen's (A. alternata) presence only in the seed coat. Embryos and cotyledons were found free from infection. None among the ten cultivar/genotype studied was found completely free from seed infection by Alternaria alternata. SKM-0201 recorded highest (11 .50 %) seed infection, whereas least (5.75 %) was observed in cultivar GM-1. Of the seven fungicides evaluated against A. altemata in in vitro, hexaconazole showed complete inhibition of mycelial growth. Copper oxychloride @ 0.15 per cent, mancozeb @ 0.20 per cent and thiram @ 0.20 per cent showed 91.44, 82.23 and 77.27 per cent inhibition, respectively. Among the two plant extracts, neem leaf extract @ 15 per cent showed 60.52 per cent inhibition and proved better than tulsi. Both Trichoderma viride and T. harzianum proved effective and showed 80.92 and 73.02 per cent inhibition of mycelial growth. Field evaluation of seven fungicides, two phytoextracts and one bioagent against Altemaria blight disease revealed mancozeb @ 0.2 per cent as most effective with least disease intensity (9.13 %) and increased the yield by 11.44 per cent over control. Yield differences were non significant. Iprodione + carbendazim and chlorothalonil were found next best fungicides. Bioagent, phytoextracts and only seed treatment with thiram revealed non significant differences with control for disease intensity.

    COWPEA WILT AND ITS MANAGEMENT
    (Anand Agricultural University, Anand, 2004) JEETENDER CHAUHAN; Dr. K. R. JOSHI
    Cowpea (Vigna unguiculata (L.) Walp.) is one of the important pulse crop mainly grown as fodder, vegetable, pulse and green manure crop in India. Cowpeas are susceptible to a very wide range of pathogens, which attack the crop at all stages of growth. Among them Fusarium wilt caused by Fusarium solani is one disease which brings down the production and productivity. Looking to the importance of the disease in Middle Gujarat, the present investigation was carried out to generate scientific information for management of disease

    PROTEIN PROFILING OF ISOLATES OF TRICHODERMA HARZIANUM RIFAI TOLERANT TO PESTICIDES
    (Anand Agricultural University, Anand, 2004) M.M.Christian; Dr. R.N.Pandey
    Due to cosmopolitan nature and easy cultivation most of the species of Trichoderma have been utilized as agents for biological control of a number of important seed/soil-borne plant pathogenic fungi. Among the known specieses, Trichoderma harzianum Rifai is the most commonly used biocontrol agent. Trichoderma spp. produce enzymes such as cellulase, chitinases, chitosanases and glucanases. Which help the bioagent to act as mycoparasite. Therefore, investigation on antagonism of T. harzianum against seed/soil-borne plant pathogens; sensitivity of the bioagent to fungicides, insecticides, nematicides and weedicides; induction of higher tolerance in efficient isolate of T. harzianum to higher concentrations of pesticides and protein profiling of efficient and pesticides tolerant isolates of T. harzianum were carried out.
