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.

    EVOLVING METHODS FOR CONSERVATION OF GEOCORIS OCHROPTERUS FIEBER (HEMIPTERA: LYGAEIDAE)
    (AAU, Anand, 2000) JHA, ANAND; YADAV, D. N.
    Methods for conservation of Geocoris ochropterus Fieber (Hemiptera : Lygaeidae) were evolved during 1999-2000 at Anand Campus of Gujarat Agricultural University and farmer's field at Awakhal village of Vadodara district. G. ochropterus was produced in the laboratory on cold stored pupae/field collected aphid, Aphis gossypii Glover and reintroduced in the cotton growing area where it was eliminated. The results indicate that the predator could successfully survive, reproduce and thus maintain substantial population. The predator was also observed to survive on other economical crops as well as weed hosts after removal of cotton. However, it remains to be seen how it over summers in the release site. The studies on conservation revealed that the predator can be conserved in cotton by interspersing maize and also by providing suitable refugia viz., maize prior to removal of the main crop i.e. cotton. The predator was found maintaining a sizable population on crops like ratoon cotton, maize, sorghum, bajra, paddy, groundnut, lucerne and Chrozophora rottleri. Methyl-o-demeton, endosulfan, fenvalerate and cypermethrin normally used in cotton were found to have detrimental effects on the predator. Sizable population of G. ochropterus perish during mowing operation (of sunnhemp) done by tractor mounted disc harrow. In view of this, mowing by tractor mounted disc harrow should be avoided. It could be concluded that G. ochropterus sustained after its re-introduction in insecticide free cotton. Such introduction in other cotton growing areas after knowing its status should be attempted.
