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.

ThesisItem Open Access STUDIES ON NATIVE ISOLATES OF ENTOMOPATHOGENIC NEMATODES AGAINST Spodoptera litura (Fabricius) AND Spodoptera frugiperda (J. E. Smith)(DEPARTMENT OF NEMATOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Prajapati Maitri Rajeshkumar; Dr. Ajay Kumar MaruThe studies on native isolates of entomopathogenic nematodes against Spodoptera litura and Spodoptera frugiperda were carried out in the Department of Nematology, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during Kharif and Rabi 2020-21. A total, 103 soil samples were collected from different habitats, viz., fruit crops, field crops and fallow land of the AAU campus, Anand. Out of these, three were found positive and collected from three different locations, i.e., Horticultural farm (Mango), Veterinary College Garden and International Agri-Business Management College. The frequency of occurrence of these nematodes was 2.9 per cent and they belonged to the genus Steinernema. Nematode cultures from different locations were considered isolates and designated Steinernema sp. (AAU St-1), Steinernema sp. (AAU St-2) and Steinernema sp. (AAU St-3). Among three, Steinernema sp. (AAU St-1) was successfully maintained under laboratory conditions. Based on the morphometrics, Steinernema sp. (AAU St-1) was found similar to Steinernema ritteri.ThesisItem Open Access STUDIES ON ROOT-KNOT NEMATODES (Meloidogyne spp.) ON INDIAN BEAN (Lablab purpureus L.)(DEPARTMENT OF NEMATOLOGY B. A.

R.Studies on cured leaf extract of bidi tobacco on root-knot nematodes were carried out at Bidi Tobacco Research Station, Gujarat Agricultural University, Anand Campus, Anand-388 110, Gujarat, India. Various aspects such as effect of the extract on egg hatching, juveniles mortality and infectivity, root-knot disease, growth and development of bidi tobacco cv. Anand 119 (A 119) as well as okra cv. Pusa Savani and reniform nematode were studied. Studies on cured leaf extract (1,5,10 and 15 per cent) of bidi tobacco {Nicotiana tahacinv L.) cv. Gujarat Tobacco 5 (GT 5) on egg hatching of rootknot nematodes {Meloidogyne spp.) revealed partial ovistatic and ovicidal action on egg hatching of root-knot nematodes. Higher concentrations of cured leaf extract of tobacco (5, 10 and 15 per cent) possessed more pronounced ovicidal action. The treatments of 10 and 15 per cent concentrations were at par to 1 per cent phenamiphos (Nemacur 10 CG @ 10 per cent) in this regard Results on effect of cured leaf extract (1, 5 and 10 per cent) of bidi tobacco cv. GT 5 on juveniles (J2) of root-knot nematodes showed immobilizing effect of the extract on the juveniles within one hour of inoculation. The immobilized larvae were revived on transfer in water indicating its nematostatic effect while significantly less number of larvae were revived in phenamiphos 1 per cent (Nemacur 10 CG @ 10 per cent) showing its strong nematicidal action. With increase in contact or exposure hours (1 to 96) and concentrations of the extract, more pronounced nematicidal action of the extract on juveniles was observed. Inoculation of revived juveniles successfully infected the roots of okra in pots. Effect of cured leaf extract (1 and 5 per cent) of different varieties of bidi tobacco viz., A 119, GT 5 and Gujarat Tobacco Hybrid 1 (GTH 1) as well as chewing tobacco (N. rustica L.) cv. Gujarat Culcatti 1 (GC 1) on egg hatching of root-knot nematodes indicated partial ovistatic or ovicidal effect of both the doses of bidi tobacco cv. A 119 and 1 per cent dose of cv. GT 5 while strong ovicidal effect of both the doses of cv. GTH 1 and 5 per cent dose of GT 5 as well as both the doses of chewing tobacco cv. GC 1. Studies on various contact durations/exposure periods (1 to 120 hours) and concentrations (1,5, 10 and 15 per cent) on egg hatching of root-knot nematodes in cured leaf extract of bidi tobacco cv. GT 5 revealed that with increase in concentrations, there was corresponding reduction in egg hatching, increase in contact durations upto 48 hours, correspondingly reduced the egg hatching and thereafter, beyond 72 hours to 120 hours, erratic trend was observed. Interactions between contact durations and concentrations of the extract correspondingly reduced egg hatching upto 48 hours of contact duration. Comparison between control and rest of the treatments of extract and durations revealed significant reduction in egg hatching within the extract and on transfer of the egg masses in water, showing ovistatic or ovicidal action of the extract on egg hatching of root knot nematodes. Studies on cured leaf extract of bidi tobacco cv. GT 5 on growth and development of bidi tobacco cv. A 119; okra cv. Pusa Savani and root-knot disease as well as reniform nematode on bidi tobacco cv. A 119 were carried out in pots. Applications of cured tobacco leaf extract @ 100 ml per pot, twice or thrice, at 15 days intervals, either at 1 or 10 per cent concentrations, significantly reduced root-knot disease by reducing/delaying/preventing larval penetration and nematode multiplication but could not significantly improve the plant growth of bidi tobacco cv. A 119 over control 45 days after transplanting (DAT). All the treatments significantly reduced root-knot disease and larval penetration in the roots of okra cv. Pusa Savani over control as well as reduced nematode multiplication, which in turn significantly improved various plant growth characters in different treatments. Three applications of higher dose of 10 per cent concentration remained significantly superior over control with respect to all the characters studied. Results on reniform nematode (Rotylenchulus reniformis) in bidi tobacco cv. A 119 exhibited similar trend as observed for root-knot nematodes in bidi tobacco cv. A 119. Results on effect of cured leaf extract of bidi tobacco cv. GT 5 on growth and development of bidi tobacco cv. A 119, root-knot disease and nematodes in nursery revealed that drenching of cured tobacco leaf extract @ 2 1 per sq.m. at an interval of 15 days, two or three times, either with 1 or 10 per cent concentrations, significantly increased number of transplantable and total surviving seedlings over control and also reduced root-knot disease. The population of reniform, root-knot and stunt nematodes was also drastically reduced at seeding and thereafter till 68 days after seeding (DAS) due to the treatment.ThesisItem Open Access INVESTIGATIONS ON ROOT-KNOT NEMATODES (Meloidogyne spp.) INFECTING MUNGBEAN (Vigna radiata (L.)
