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.

    ROLE OF AVIAN PREDATORS IN HELIOTHIS ARMIGERA (HUBNER) MANAGEMENT AND BREEDING BIOLOGY OF THE BANK MYNA ACRIDOTHERES GINGINIANUS LATHAM
    (AAU, Anand, 1989) PARASARA, U. A.; PARASHARYA, B. M.
    Studies on role of avian predators in the management H. armiKera. assessment of depredation, other mortality factors and breeding biology of one of the chief predatory species Acridotheres ginginianus Latham were carried out at Anand Campus of Gujarat Agricultural University, during 1988 and 1989. The net installed at 2 m height above the crop facilitated- movement of Heliothis moths across the net. The birds activity started as soon as the medium and large larvae appeared in the field. During both the years, mean number of small larvae was equal in T1 and T2 while medium and large differed significantly, mainly due to the bird predation in open area. Two sprays of endosulfan - 0.07 % significantly reduced larval number but the yield was higher only in the area grown at 60 cm distance. Slightly more inter-row distance (60 cm) improved efficiency of predatory birds. In bird free area (netted) pod damage was always high and hence the yield was very poor compared to the open area where birds controlled the pest. The Heliothis eggs were totally free from parasites whereas the small larvae were parasitised by Campoletis cl-qorideae to the tune of 23 per cent and 15.33 per cent during 1988 and 1989 respectively. Very poor pupal recovery was attributed to the inability of larvae to pupate in very hard soil, and predation by squirrel. The activity of predatory birds was comparatively less during morning hours (0730 to 1030) compared to evening (1430 to 1830) hours and no activity was observed inbetween., Due to the birds preference to forage in wider spaced crop, larval population was significantly less compared to closer spaced area. The breeding season of the Bank Myna A. ginginianus. extended from the 1st week of May to last week of the August, with peak period during dry weather of May and ijune. Average egg size was 2.68 x 1.88 cm; weight 5.600 gm and average volume was 5.22 cc. The mean clutch size varied between 3.78 to 3.88. Average incubation period ranged between 12,73 - 12,80 days whereas nestling period ranged between 22.47 to 23.45 days. Hatching success was higher in dry period as compared to wet period. The entry of rainywater. Black ants and ectoparasitic mites were chief mortality causing factors in wet period. Nestling food studies show that the Bank Myna feed their youngs mainly on animal matter (95.59 per cent) of which insects contributed 84.73 per cent. Bank Myna used very wide range of nesting material which included plant, Animal and synthetic materials. Key words : Gram, Bird predation, Heliothis armigera. larval parasitism, Campoletis chlorideae. Bank Myna Acridotheres ginginianus. breeding biology

    EVALUATION OF VARIOUS INSECTICIDES AGAINST PEST COMPLEX OF BHENDI (Abelmoschus esculentus L.) AND BRINJAL (Solanum melongena L.)
    (AAU, Anand, 1989) PATEL, C. J.; PATEL, J. R.
    The study carried out to determine the efficacy of various insecticides agiainat pest complex of bhendi and brinjal during different season indicated the effective control of aphid Aphis gossypii G. within 24hrs , on kharif bhendi by application of mixture of endosulfan 2% dust + methyl parathion 2% dust @ 15 +15 kg/ha. Whereas, application of endosulfan 2% dust @ 15 kg/ha, endosulfan 2% dust + quinalphos 1.5 % dust @ 15 + 15 kg/ha, indiara 1 % spray and neemark 0.5% spray effectively checkeck the multiplication of jassid, Amrasca biguttula biguttula I . population on kharif bhendi till one week after application. The jassid infestation on summer bhendi was controlled by spray application of acephate 0.075 % and 5 % neem seed kernel paste suspension till two weeks after application. The infestation of Earias vittella F. in the shoot of kharif bheadi was effectively controlled by dusting of endosulfan 2 % dust quinalphos 1.5 % dust mixture @ 15+15 kg/ha. The spray application of 5 % neem seed kernel paste suspension and acephate 0.075 % were found very effective on summer bhendi in neducing the shoot damage caused by E.vittella . The fruit damage in Kharif bhendi was reduced by dust application of endoaulfan 2 % dust @ 15 kg/ha and a mixture of endosulfan 2 % dust + quinalphos 1.5% dust @ 15+15 kg/ha as well as spray application of 5 % neem seed kernel paste suspension, Aphidophagous lady bird beetle, Menochilus sexmaculatua had least toxic effect of spray application of 5 % neem seed kernel paste suspension on Kharif bhendi, No parasite activity was found in treated as well as untreated kharif bhendi. The bhendi varieties Parbhani Kranti, Selection-2 and Gujarat Okra-1 cultivated during summer were less infested with jassid, A. biguttula biguttula till 11 weeks after sowing. No need of insecticidal application was realized in bhendi variety Selection-2 for the control of jassid. Whereas, maximum protection was obtained with insecticidal application in Gujarat Okra-l. Padra 18-6 had significant susceptibility to mite, Tetranychus telarius as con5)ared to other varieties which were found equally susceptible.

    STUDIES ON THE VARIETAL PREFERENCE OF VARIOUS INSECTPESTS TO BHENDI (Abelmoschus esculentus L.)
    (AAU, Anand, 1989) VYAS, S. H.; PATEL, J. R.
    The study on population dynamics of various insectpests damaging to different varieties of bhendi (Abelmoschus esculentus L.) screened under field conditions during kharif 1987 and 1988 indicated that aphid, Aphis gossypii G. and jassid , Amrasca biguttula biguttula I. incidence on all the varieties was high and for a longer period during kharif 1988 as compared to kharif 1937. However, jassid population was low on Selection-2 and GO-1 as compared to Padra 18-6. The damage of shoot and fruit borer, 'E. vittella F. to shoots of different bhendi varieties was observed during August. The damage of 'Farias to shoots of Selection-2 was comparatively less than other varieties. The incidence of E. vittella in the fruits was started from the third week of August and continued till removal of crop. However, in the early part of the fruit formation, fruits of Punjab Fadiniai and Selection-2 were less damaged than other varieties. The incidence of yellow vein mosaic disease in all the 'bhendi' varieties started from middle of August, however, PB-57 (Tarhhani Kranti) was completely free from disease throuihout the crop season. Significant positive correlation, was found between disease incidence and maximum temperature. None of the 'Bhendi' varieties was found resistant/ tolerant to aphid and jassid. However, bhendi varieties GO-l, Selection-2, PB-57 and Punjab ladmini were found resistant / tolerant to shoot and fruit borer, E. vittella whereas, Padra 18-6 and Fusa Sawani were moderately susceptible . The variety PB-57 (Parbhani Kranti) was completely free from yellow vein mosaic disease. The study on the effect of different 'bhendi' varieties on biology of E. vittella revealed that larvae reared on Padra 18-6 had a long larval period and short pupal periodo whereas longevity of male and female moths was long from the larvae reared on Padra 18-6 and Pusa Sawani, respectively. Inoubatioa period of eggs laid by moths obtained by rearing on Punjab Padmini was long. Ihe ahorteat life span of male and female Earias was found on Pusa Sawani and Selection-2, respectively, whereas, longest life span of male was observed on PB-57 and female on Pusa Sawani. Hale to female ratio was 1:1 on Punjab paimini whereas mora males were emerged by rearing on Selection-2. Female moth emerged from larvae reared on PB-57 had short pre-oviposition and long ovi-position period, whereas moths obtained from Selection-2 had long preoviposition and short ovi-position period. Post-oviposition period of moths obtained from Padra 18-6 and piisa Sawani was short and long, respectively. The minimum and maximum larval mortality was found in larvae reared on Pusa Sawani and GO-l respectively. The minimum and maximum larval penetration was found in fruits of Selection-2 and Pusa Sawani, respectively. Fruits of all the six 'bhendi' varieties were equally preferred for oviposition.
