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.

    STUDY OF LUCERNE (Medicago sativa L.) RUST (Uromyces striatus Schroet.) AND ITS CHEMICAL CONTROL IN SEED PRODUCTION CROP
    (AAU, Anand, 1982) GHELANI, GANESH K.; Patel, A. J.
    Lucerne (Medicago sativa L.) was found suffering from rust, downy mildew, common leaf spot, Phytophthora root rot and Fusarium wilt in and around Anand area. Rust disease is assuming alarming proportion since last two-three years and causing considerable damage to the crop. Fungus Uromyces striatus Schreet. (Syn. U. striatus var medicaginis (Pass.) Arth.) on lucerne produces ured spores which are one celled, glohoid to broadly ellipsoid, 18-23 x 17-22 µm with 1-2 µm walls, evenly echinulate, yellowish brown with three to four equatorial pores, and on hyaline pedicels (Plate-1).

    TOXICITY OF METALAXYL AGAINST PYTHIUM APHANIDERMATUM (EDSON) FITZPATRICK AND PHYTOPHTHORA PARACITICA VAR. NICOTIANAE (BREDA DE HAAN) TUCKER IN TOBACCO
    (AAU, Anand, 1985) Bhatt, Premal A.; Patel, D. J.
    Toxicity of different formulations of metalaxyl viz. Apron 35SD, Ridomil 25WP, R+MZ 72WP and M+ZI 280FW was studied against Pythium aphanidermatum and Phytophthora parasitica var. nicotianae (in vitro and in vivo). Residue study of metalaxyl (Apron 35SD) was also carried out. Among the different concentrations of various metalaxyl formulations studied against Pythium aphanidermatum in vitro. Apron 35SD, Ridomil 25WP and R+MZ 72WP each at 100 ppm concentration gave cent per cent inhibition of fungus growth, while in vivo, soil drenching with Apron 35SD, Ridomil 25WP and R+mz 72Wp each at 100 ppm concentration effectively managed the daraping-off disease. In vitro study of various raetalaxyl formulations at different concentrations against Phytophthora parasitica var. nicotianae^ the results revealed that Apron 35SD at all the concentrations viz. 100, 10, 1 and 0.1 ppm, Ridomil 25WP at 100, 10 and 1 ppm, R+mz 72WP at 100 and 10 ppm and M+ZI 280FW at 100 ppm concentration completely checked the fungus growth. Regarding their effectivity in vivo, soil drenching with R+MZ 72 wp at 100 ppm concentration effectively managed the black-shank disease. Results obtained from residue study of metalaxyl (Apron 35SD at 3%) indicated that uptake of metalaxyl by tobacco seedlings was maximum (9040 ppm) at tenth day after seed germination while it was minimum (4700 ppm) at fifth day after seed germination.

    STUDY OF EFFICIECY OF INDIGEOUS RHIZOBIAL POPULATION NODULATING LEUCAENA (LEUCAENA LEUCOCEPHAIA LAM.)
    (AAU, Anand, 1984) PATEL, M. A.; Sheth, R. D.
    Leucaena (Leucaena leucocephala Lam.) is one of the important forage crop grown in tropical and subtropical countries. Since leucaena is inoculated with Rhizobium culture, attempts were made to find out suitable strain of Rhizobium for leucaena. Rhizobia were isolated from the nodule of leucaena formed by native rhizobia present in the two soil types, one from the ‘Goradu’ soil samples of Anand and other from ‘medium black’ soil sample of Aiska farm (Thasra). A standard inoculant strain TAL-602 was also used for study. Efficiency of isolated rhizobia and standard inoculant strain were studied under glasshouse conditions by using ‘Leonard Jar Technique’ at 30th, 50th and 70th day period of plant growth after inoculation of rhizobia.

    TRICHODERMA HARZIANUM-A POTENTIAL BIO-CONTROL AGENT FOR TOBACCO DAMPING-OFF
    (AAU, Anand, 1983) BRAHMBHATT, ASHOK B.; Mukhopadhyay, A. N.
    Antagonistic activities of an isolate of Trichoderma harzianum Rifal against tobacco isolate Pythium aphanidermatum was studied in vitro. T. harzianum directly attacks the hyphase of P. aphanidermatum. In dual culture of the two fungi P. anhanidermatum was antagonized by T. harzianum. Volatile and non volatile antibiotic activity of T. harzianum towards P. anhanidermatum could be detected.

    STUDY OF SEED MYCOFLORA ASSOCIATED WITH COWPEA (VIGNA UNGUICULATA (L.) WALP.) AND GRAM (CICER ARIETINUM L.), THEIR PATHOGENICITY AND CONTROL
    (AAU, Anand, 1984) GOHEL, VIKRAM R.; Sheth, R. D.
    Seed borne pathogens play a vital role in causing diseases of pulse crops. Hence, with a view to study mycoflora and their role, seed samples of two pulse crops viz. cowpea (Vigna uaguiculata (L.) Wal.p.) and gram (Cicer arietinum, L.) were tested for determining the range of mycoflora associated with seeds. The isolations were made on moist blotting paper and potato dextrose agar with and without pretreatment with 0.1 percent mercuric chloride. From, seeds of both the crop, 22 fungi were detected, out of which Macrofomina phaseolina, Colletotrichum sp. Penicillium, oxalicum. Fusarium. spp., Chalara state of Ceratocystis paradoxa, Curvularia lunata, Aspergillus tamarii. A. flavus and Altenaria sp, were found as strong pathogens on cowpea and gram, both under laboratory and glass house conditions. Next in order were Aspergillus niger van. Tieghem, A. ochraceus, Corynespora cassicola, Penicillium variabile and Aspergillus flavus.

    (AAU, Anand, 1984) KADVANI, D. L.; Sheth, R. D.
    Chickpea (Cicer arietinum L.) is one of the chief legume crop grown in India. Since chickpea is inoculated with Rhizobium culture, attempts were made to find out suitable strain of Rhizobium for chickpea.Rhizobia were isolated from the modules of chickpea formed by negative rhizobia present in the soil i.e., ‘medium black’ (Saline) soil samples of Ghed (Junagadh) and Bhal (Arnej) and ‘Goradu’ soil samples of Anand and Dahod. A standard inoculant strain IC 108 was also used for study. Efficiency of isolated rhizobia and standard inoculant strain were studied under glasshouse conditions by using ‘Leonard Jar Technique’ at 25th, 45th and 70th day period of plant growth after inoculation of rhizobia.

    AFLATOXINS ELABORATION BY ASPERGILLUS FLAVUS AS AFFECTED BY VARIETIES, TEMPERATURE AND RELATIVE HUMIDITY IN GROUNDNUT (ARACHIS HYPOGAEA L.)
    (AAU, Anand, 1983) DESAI, A. G.; Sheth, R. D.
    Groundnut (Arachis hypogaea L.) is an important oilseed crop grown in India. Groundnut is said to be one of the best substrates for aflatoxins production. Contamination o£ groundnut seeds with the toxic and carcinogenic aflatoxins produced by the fungus A. flavus causes a hazard to animals and human health. In view of the importance of the genetic approach for the prevention of aflatoxins production on groundnut, five varieties of groundnut commonly grown in Gujarat State were screened against an aflatoxigenic isolate of A . flavus under artificial conditions of inoculation. Aflatoxins B1 and C1 were produced in all five groundnut varieties, although they differed In the quantity of aflatoxins production. None of the varieties showed resistance to the toxigenic isolate of A. flavus, however the variety J 11 showed a moderately resistant type of reaction to aflatoxins production as compared with other four.
