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 CHEMICAL CONTROL OF THE PEST COMPLEX OF SORGHUM WITH SPECIAL REFERENCE TO SHOOTFLY AND STEM BORER(AAU, Anand, 1981) PATEL, JITENDRA R.; JOTWANI, M. G.Abstract not AvailableThesisItem Open Access ECOMOMIC THRESHOLD OF INSECTICIDAL SPRAYINGS AGAINST BOLLWORMS (Heliothis armigera (Hb.) and Earias spp.) ON HYBRID-4 COTTON AT ANAND. (Comparison of need-based and calendar-based treatments)(AAU, Anand, 1980) Mulchandani, Lachmandas Nassanand; Patel, H. K.In a split plot designed experiment carried out during the years 1977-78 and 1978-79 the three treatment levels (damage thresholds) of 10, 15 and 20 percent bollworm damage to fruiting bodies of selected size-group (from full grown squares to young bolls) were evaluated on calendar-based and need-based schedules for their effects on yield, number of undamaged bolls, bollworm damage to retained bolls and loculi, shedding of fruiting bodies, and earliness in maturity. The applications of carbaryl 0.25 percent + DDT 0.25 percent mixture at 10 and 15 percent treatment levels were found to be equally effective in giving a maximum yield of (good seed cotton) when they were continued on need basis (Average 3506 and 3117 kg/ha at 10 and 15 percent levels respectively) and weekly basis (Average 3852 and 3409 kg/ha at 10 and 15 percent levels respectively). Amongst three frequencies of application under fixed schedules, the weekly-based frequency of application was the best.ThesisItem Open Access STUDIES ON CATOPSILIA PYRANTHE LINN. (LEPIDOPTERA: PIERIDAE) A PEST OF SENNA, CASSIA ANGUSTIFOLIA VAHL. IN ANAND (GUJARAT)(AAU, Anand, 1987) PATEL, H. M.; Yadav, D. N.Captopsilia pyranthe Linn. (Lepidoptera : Pieridae) has been reported as a serious defoliator of a medicinal crop, Senna, Cassia angustifolia Vahl. Studies on its biology, seasonal abundance, natural enemies and chemical control were carried out at Anand Campus of Gujarat Agricultural University during 1983-84 and 1984-85. Biological observations revealed that, the pest lays eggs singly on the foliage which hatch out in two days. It passed through five distinct larval instars to complete its development and duration of each instar was on an average 1.20, 1.12, 1.32, 1.68 and 2.83 days during June (when average minimum and maximum temperatures were 30.49 °C and 38.00 °C and relative humidity was 68.3 per cent and 1.73, 1.33, 1.60, 1.93 and 3.13 days during September and October (when average minimum amd maximum temperatures were 27.71 °C and 34.75 °C respectively and relative humidity was 59.09 per cent) respectively.ThesisItem Open Access BIOLOGY, POPULATION DYNAMICS AND CONTROL OF HELIOTHIS ARMIGERA HUBNER ON IMPORTANT HOST CROPS IN MIDDLE GUJARAT(AAU, Anand, 1993) Mehta, D. M.; Patel, J. R.Investigations on biology, population dynamics and control of H. armigera on important host crops were carried out during 1990-91 and 1991-92 at the Department of Entomology, Gujarat Agricultural University, Anand Campus, Anand. The effect of larval food was not observed on egg period but larval period was affected. The larval period was shortest on lucerne (Medicaso sativa L.) leaves and longest on chickpea (Cicer arientinum L.) leaves. The maximum and minimum larval survival for both the sexes was . on chickpea pods and chickpea leaves respectively. it was reflected on growth index. The pupal duration on chickpea pods was short. The pupae obtained by rearing the H. armigera larvae on lucerne leaves and chickpea pods were big in size and pupation was very shallow. The adults obtained from lucerne leaves had long oviposition period and high fecundity. The life span for both the sexes was longest onchickpea leaves followed by tomato fruits, pigeonpea pods, tomato leaves, chickpea pods and lucerne leaves. The studies on population dynamics of H. armigera on various crops, weeds, medicinal and ornamental plants revealed ovipositional and larval activity during July to April. The correlation of various abiotic factors with U- armigera activity on pigeonpea showed negative correlation between egg density and soil temperature. Negative and positive association of minimum temperature, vapour pressure and soil temperature was observed with oviposition on tomato and lucerne, respectivly. On pigeonpea and chickpea larval activity was more influenced by soil temperature, whereas, on lucerne minimum temperature, vapour pressure, and soil temperature influence was observed. Considerable activity of an egg parasitoid Trichogramma spp. was found in the fields of tomato, tobacco and pigeonpea in middle Gujarat during October to December. Preliminary studies on resistance in 21 genotypes and 3 local cultivars of tomato to H. armigera revealed low damage to unriped fruits of Karnataka and Mangala and riped fruits of SL 120, F24C8 and Piersol. Karnataka and Mangala had higher marketable fruit yield than others. The degree of fruit damage by H. armigera was positively related with total soluble sugar and negatively with ascorbic acid. Low ovicidal and high ovipositional deterrent effect of neem seed kernel suspension and margoside was found against H. armigera. The spray application of these two botanicals alone as well as combinations with endosulfan at lower concentration gave effective protection to tomato fruits by preventing the larval activity of H. armigera and gave considerably higher marketable fruit yield. The spray application of neem seed kernel suspension with endosulfan had highest increase in yield and avoided 69.33% loss in marketable fruit yield. The residue of endosulfan in/on tomato fruits was quite below the tolerance limit prescribed by FAO/WHO when tomato crop was sprayed with a mixture of endosulfan 0.035% and neem seed kernel suspension (3%). Among the various recommended insecticides, fenvalerate (0.01%) showed quick and high toxicity to H. armigera larvae. The larvae fed on lucerne had higher susceptibility to all the recommended insecticides than the larvae fed on pigeonpea and chickpea.ThesisItem Open Access EVALUATION OF GRAIN PROTECTANTS AGAINST Callosobruchus analis F. INFESTING GREEN GRAM Vigna radiata (L) Wilozek.(AAU, Anand, 1990) GEORGE, V.; Patel, J. R.The relative bio-efficacy of some botanical, and other materials in comparison to synthetic insect- cides against pulse beetle Callosobruchus analis F. infesting green gram Vigna radiata (L.) W, was evaluated in laboratory during 1989-90. The synthetic insecticides, malathion and fenvalerate were used @ 0.05 and 0.02 per cent respectively, while the rest of the treatments were @ 10 per cent (w/w) except corn-care, which was at 1 per cent. The seeds under control treatment was sprayed with double distilled water (10 per cent-v/w) only. Five adults of C. analis i.e. three females and two males were released to the treated green gram. The green gram stored with various botanical materials, synthetic insecticides and other grain protectants had comparatively low oviposition by pulse beetle C.analis as compared to untreated grains on the 10th day of releasing the insects.ThesisItem Open Access BIOLOGY AND CONTROL MEASURES OF BROWN SCALE, SAISSETIA COFFEAE WALKER ( HOMOPTERA : COCCIDAE) ON POINTED GOURD (TRICHOSANTHES DIOICA ROXB.)(AAU, Anand, 1986) VALAND, VITTHALBHAI M.; Patel, R. C.The biology and control measures of brown scale, Saissatia coffeae Wlk. (Homoptera : Coccidae) on pointed gourd (Trichosanthes dioica Roxb.) were studied. This scale is recorded for the first time as pest on pointed gourd on vines, leaves and at times on fruits in Gujarat State. It reproduces partnenogenetically and completes development through three instars. The eggs measured 0.212 ± 0.0096 mm. In length and 0.119 ± 0.006 mm. In breadth. The first, second and third instar measured on an average 0.31 ± 0.02, 1.521 ± 0.091 and 3.021 ± 0.144 mm. In length and 0.18 ± 0.1, 1.126 ± 0.101 and 2.427 ± 0.225 mm. in length and 2.093 ± 0.187 mm. In breadth. Maximum incubation period of eggs at 60% relative humidity and 24°C was 12.91 days.ThesisItem Open Access BIOLOGICAL STUDIES ON Euplectrus xanthocephalus Girault A NEW ECTO-LARVAL PARASITE OF Spodoptera litura ( Fab.)(AAU, Anand, 1983) VIRANI, VALLABH R.; YADAV, D. N.Biological studies on the Eulophid parasite, Euplectrus xanthocephalus Girault parasitising Spodoptera litura Fab. were made in the laboratory during 1981-82 at the Anand Campus of Gujarat Agricultural University. The studies revealed that the Euplectrus females laid their eggs in groups of 6 to 8 on the 2nd to 5th stage larvas. The eggs hatch out in 1.2 to 1.9 days and the parasite larvas start feeding the host externally, The larvae pass through 5 instars to complete their development in 4.95 to 5 days. They undergo a short prepupal stage which lasts for 2.03 days. The pupation occurs underneath the dead host larvas. The pupal stage varied from 5.06 to 6.06 days. The entire development of the parasite from egg deposition to adult emergence varied from 9.0 to 11.60 days.ThesisItem Open Access STUDIES ON THE BIO-EFFICACY OF SOME INSECTICIDES AGAINST INSECT PESTS OF HYBRID-4 COTTON(AAU, Anand, 1982) KABARIA, BABU B.; Chari, M. S.To evaluate the bio-efficacy of some insecticides against insect pests of Hybrid-4 cotton, an experiment was conducted for two years during 1980-81 and 1981-82. The first trial was conducted during 1980-81 with the following treatments viz. Phenthoate-EC (Elsan, 50 EC, 1.625 l/ha), endosulfan (Thiodan, 35 EC, 1.5 l/ha), chlorpyriphos (Damisban, 20 EC, 1.25 l/ha), carbaryl (Sevin, 50 wp, 2 kg/ha), phenthoate-D (Elsan, 2% dust, 31 kg/ha), diazinon (Bazanon, 20 EC, 1 l/ha), monocrotophos (Nuvacron, 40 EC, 1.5 l/ha) and control (water spray only). Seven spraying were given at an interval of 15 days. The results on sucking insect pest complex showed that monocrotophos gave excellent protection to the crop from aphids, jassids and thrips.ThesisItem Open Access EVALUATION OF ELECTROSTATIC SPRAYING SYSTEM (ELECTRODYN) IN COTTON PEST MANAGEMENT(AAU, Anand, 1987) MURALIDHARAN, C. M.; CHARI, M. S.The efficiency of Electrodyn sprayer in the management of sucking pests and bollworms of cotton v/as evaluated along with three conventional Knapsack, Mistblower and Heli sprayers during 1983, 1984 and 1985. ED and EC formulations of cypermethrin were used fur evaluation. The toxicity of these formulations on predators and also the quantity of spray fluid deposited per unit area by various sprayers were studied. A field experiment was conducted with six treatments for the Electrodyn sprayer viz. 3% ED-0.05 ml/sec, 3% ED-0.1 ml/sec, 2% ED-0.05 ml/sec, 2% ED-0.1 ml/sec, 1.5% ED-0.1 ml/sec and 4.5% ED-0.05 ml/sec and three for Knapsack (cypermethrin 100 ppm), Mistblower (cypermethrin 200 ppm) and Heli sprayers (cypermethrin 50 gm a.i./ha) (Total nine treatments were taken Efficiency of different sprayers in reducing the sucking pest population (Aphids, Jassids, Whiteflies and Thrips) indicated that all the sprayers are equally effective in suppressing the sucking pests.
