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.

    ROOT-KNOT NEMATODES IN WHEAT
    (AAU, Anand, 1987) PATEL, YOGESHKUMAR CHANDUBHAI; Patel, D. J.
    The experiments on root-knot nematodes (Meloidogyne spp.) in wheat were conducted to study (I) Inoculum potential in relation to growth and development of wheat plants, (ii) Effect of root-knot nematodes infection on biochemical changes in wheat plants, (iii) Effect of nematode infection on meteorological parameters, (iv) Assessment of losses due to root0knot nematodes, (v) Varietal reaction to root-knot nematodes and (vi) Histopathology using wheat variety Sonalika during 1985-86.

    INTERACTION BETWEEN ROOT-KNOT (MELOIDOGYNE INCOGNITA AND MELOIDOGYNE JAVANICA) AND RENIFORM (ROTYLENCHULUS RENIFORMIS) NEMATODES IN BIDI TOBACCO
    (AAU, Anand, 1986) PATEL, SOMABHAI KESHAVLAL; PATEL, A. J.
    The experiments on Intaraction between root-knot (Meoidogyne Incognita and Meloidogyne Javanica) and reniform (Rotylenchulus Reniformis) nematodes In bidi tobacco ward conducted to study the effect on growth and development of tobacco plant, nutrients uptake by tobacco plant, intensity of root-knot and reniform nematodes, Influence of meterological parameters on tobacco plant and histopathology using tobacco variety, Anand 119 during 1985-86. The experiment on interaction between A. Incognita and R. Reniform indicated that inoculation of A. Incognita alone or in combination with R. Reniform had more depressing effect on growth and development of tobacco plant ultimately reducing uptake and translocation of various nutrients viz., N, F, K.

    STUDIES ON ARHAR (CAJANUS CAJAN (L.) MILLSP.) WILT CAUSED BY FUSARIUM SOLANI AND ITS CONTROL
    (AAU, Anand, 1988) PATEL, Ashok R.; PATEL, B. K.
    Pigeon-pea (Cajanus cajan (L.) Millsp.) is an important pulse crop after gram in India. This crop is suffering from as many as 50 diseases. Among them, wilt and sterility mosaic are important one. Pigeon-pea wilt is one of the serious diseases, causing considerable damage to the crop in our country. Fungus (Fusarium solani) grew best on Richard's medium followed by potato dextrose broth. Potato dextrose broth supported maximum sporulation of the fungus followed by Richard's medium. An incubation of 15 days, 6.0 pti 0 and 27°C temperature were found best for the growth of F. solani. Among different nitrogen sources, potassium nitrate supported maxitium mycelial growth. BDtassium nitrate and sodium nitrate were found as best nitrogen sources for excellent sporulation. Sucrose was found best as carbon source for maximum mycelial growth. Sucrose and mannitol were found superior for maximum sporulation. Aerobic condition was found suitable for the excellent growth and sporulation of the fungus. Highest mycelial growth was found on the leaves of cotton, groundnut, arhar and castor, while, abundant sporulation was observed on cotton, groundnut and castor leaves, Arhar leaves produced abundant chlamydospore. Sandy soil showed highest wilt incidence while, lowest in black-cotton soil. Root-knot nematode inoculation (@1,000 larvae/plant) prior to fungus inoculation enhanced wilt in susceptible cultivar T-15-15. It also broke the resistance in case of resistant variety BDN-2. Antagonistic effect of fungus or interaction effect of fungus and host was observed on nematode infection. Wilt incidence was significantly reduced by treating the soil with margosa cake. Aspergillus niger foxind superior in inhibiting the mycelial growth followed by A. flavus. In vitro studies, Bavistin 50 wp, Bavistin + TMTD (25% m/m), Agrozim 50 wp, Bsnlate, Agrosan GN, Thimm, foltaf and Ditharve M-45 checked the growth of P. solani. Among all the seed dressers, Bavistin @ 0.2% was found most effective in checking the pre emergence rot and wilt incidence caused by F. solani. Bavistin, Agrozim, Bavistin + TMTD (25% m/m) and Benlate as the seed dressers significantly improved germination percentage and reduced wilt during seedling stage under field conditions. Pigeon-pea cultivar NP (WR)-15 was found resistant against P. solani. Whereas, cultivars viz. ICP-7336 and ICP-8863 were found moderately resistant under laboratory screening.

    STUDIES ON LEAF CURL DISEASE OF TOBACCO, NICOTIANA TABACUM L.
    (AAU, Anand, 1988) TSERING, KESANG; PATEL, B. N.
    Investigations on host range, persistence of tobacco leaf curl virus (TLCV) by its vector whitefly, Bemisia tabaci Gennadius and the ability of the vector to carry TLCV and yellow-vein mosaic virus of okra simultaneously revealed that 29 out of 99 plant species belonging to 24 families were susceptible to TLCV infection when inoculated artificially through the 'vector whitefly under glasshouse conditions. Out of these, the transmission of leaf curl to five plant species, viz., Amaranthus lividus, Launaea sermentosa, Cichorium intybus, Lepidium sativum and Fagopyrum esculentum is reported for the first time. In addition to these hosts, Vinca rosea was also found to exhibit leaf curl symptoms when inoculated artificially through whitefly. Female whitefly adults when given feeding periods of 30 min, 2, 4 and 6 h on the infection source retained the infectivity upto 2, 4, 7 and 8 days, respectively after serial transfers on healthy tobacco plants. Female whiteflies retained the infectivity for a minimum of 10 days when the acquisition feeding period was prolonged to 24 h. The vector whitefly was found to transmit TLCV and yellow-vein mosaic virus of okra simultaneously to the respective hosts from which they were acquired by the vector indicating that the vector whitefly is capable of harbouring both the viruses at the same time.
