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 THERAPEUTIC EFFECT OF EPIPLEURAL AND VISCERAL PROCAINE BLOCKADE IN PRIMARY INDIGESTION CASES OF BUFFALOES (Bubalus bubalis)(AAU, Anand, 1991) Shah, Dharmendra A.; Parsania, R. R.The cases admitted to Veterinary College Hospital, Anand and Ambulatory Clinic centres at Chikhodra, Gamdi and Bedva villages were studied and 50 oases of primary indigestion were selected for therapeutic trials. The cases were grossly diagnoses on the basis of history, clinical findings and faecal sample examination. These 50 animals were divided equally into five treatment trial groups via., (a) epipleural procaine blockade (b) viscera procaine blockade (c) conventional method supplemented with epipleural procaine blockade (d) conventional method supplement with visceral procaine blockade and (e) conventional method onl Clinical observations regarding overall behaviour of the animal, its expression, ruminal motility, heart rate, respiratiorate and rectal temperature were studied before and 48 hours aft the treatment in all the five groups of buffaloes. Haematologica parameters (Hb, PCV, TEC, TLC and DLC), biochemical parameters (blood glucose and BUN) and rumen fluid analysis (colour, odour, pH, protozoal motility and total volatile fatty acids concentrate were also studied before and 48 hours after the treatment. However, in all the parameters, the changes were found non-significant and remained within their normal physiological limits. Depending upon the efficacy and the rapidity with which the cases got cured, the present study has definately indicated that the procaine blockade was better than the conventional treatment. Among procaine blockades also, the visceral procaine blockade was found to be superior and practical method having wide field applicability. The present study was restricted to fifty clinical cases of primary indigestion only. But looking to the results achieved this visceral procaine blockade can be employed in more number of cases and also in variety of conditions, which may throw a light on some hidden efficacy of the same. So, further study is needed for better understanding of the blockade and i t s wide sprea uses in veterinary practices.ThesisItem Open Access EFFECT OF CLOMIPHENE CITRATE (FERTIVET FVT 300) ON SEXUAL BEHAVIOUR AND SEMEN QUALITY IN SURTI BUFFALO BULLS(AAU, Anand, 1991) Doshi, M. B.; Derashri, H. J.The present study was undertaken to evaluate the effect of clomiphene citrate (Fertivet FVT 300) on sexual behaviour, semen quality and quantity and level of testosterons in eight Surti buffalo bulls. The experiment was divided into three phases : pre-treatment, during treatment and post-treatment; each of eight weeks keeping equal number of bulls as control. Significant (P /0.05) effect of treatment was observed on reaction time, semen volume, total sperm count, total solids, total protein, citric acid, potassium and (P /0.01) serum testosterone level. Sustained significant effect of treatment was observed on citric acid (P /0.05) and serum testosterone level (P /0.01) during post-treatment phase. Significant (P /0.05) correlations due to treatment were observed between reaction time (negative), colour and consistency; (P /0.01) total protein, citric acid and initial fructose and testosterone. It was concluded that treatment with clomiphene citrate increased the testosterone levels in blood which reduced the reaction time and increased the sperm concentration to a threshold level and activity of accessory sex glands. Post-treatment effects sustained only for few weeks.ThesisItem Open Access A GENETIC STUDY ON PERFORMANCE EFFICIENCY INDEX (PEI) ON THE BASIS OF CORRECTED BODY WEIGHT AT VARIOUS STAGES OF PRODUCTION IN WLH STRAIN(AAU, Anand, 1990) Joshi, Rajesh Kumar S.; Solanki, J.

M.The present study was undertaken with a view to know the occurrence of Staphylococcus aureus In bovine milk In relation to species, managemental conditions, breed, method of milking, parity, stage of lactation and Involvement of the quarters as well as to observe the relationships among the certain characteristics, Including enterotoxigenicIty, of S.aureus. The isolates were also phage typed to know the possible origin. The milk samples were collected from the animals maintained at six different farms comprising of four GAU farms and two private farms. The cows were maintained at four farms whereas buffaloes were maintained at remaining two farms. A total of 925 milk samples (758 from cows and 167 from buffaloes) from the individual quarters of 234 animals comprising of 191 cows and 43 buffaloes were collected and processed for isolation and identification of S.aureus. Of these, 94 quarters (10.16 per cent) of 67 animals (28.63 per cent) revealed the presence of S.aureus. The incidence of S.aureus was more commonly encountered amongst the cows on animal basis (31.94 per cent) as well as on quarter basis (11.35 per cent) than those of buffaloes (13.95 and 4.79 per cent, respectively).ThesisItem Open Access ROOT-KNOT NEMATODE, MELOIDOGYNE JAVANICA, PATHOTYPE 2, ON FENNEL(AAU, Anand, 1995) Patel, Pankajkumar B.; Patel, D. J.Experiments on root-knot nematode,. Meloidogyne javanica , Pathotype 2 affecting fennel were conducted to study i, Pathogenicity of M. javanica , Pathotype 2 to determine threshold level in terms of plant growth characters and uptake of N, P, K, Ca, Mg and S nutrients by plants, ii, biochemical changes induced by nematode infection in the crop, ill, histopathological studies to know host-parasite relationship and iv, effect of nematode infection on seed germination, plant growth and crop yield during 1994-95. The salient findings are : i, An inoculum level of 100 J2/plant and above was detrimental to the growth and development of fennel cv. PF 35. Root, soil and total nematode population/plant significantly increased progressively with an increase in nematode population from 10 to 10,000 J2/plant. Nematode reproduction rate was maximum (76.70) in the level of 10 J2/plant and minimum (3.22) in 10,000 J2/plant. ii, Biochemical changes induced by nematode feeding on fennel roots indicated that roots inoculated with 10, 100, 1,000, 5,000 and 10,000 J2/plant had significantly less peroxidase, polyphenoloxidase and total phenol content over control-uninoculated plant roots. ill, Histopathological studies revealed that after invasion, second stage larvae penetrated the epidermal cells and migrated both inter and intracellularly and anchored to the vascular tissues. Giant cells consisted of uneven thickened, unbroken walls, dense cytoplasm and clusters of nuclei. Pathological reaction included abnormal xylem located in the vascular tissues. All nematode stages were found inside the root tissues feeding on vascular region. The healthy tissue showed no change in epidermal cells and cortex region of roots, iv, Study on effect of M. .iavanica. Pathotype 2 on seed germination and plant growth development and root-knot index on fennel cv. PF 35 indicated that nematode infested soil significantly reduced fennel seed germination, plant height, fresh shoot and root weights by 12.30, 29.60, 3.98 and 17.09 % respectively over control-steam sterilized soil. Infested soil had 116.30 % increased root-knot index over control. V, Inoculation of M. javanica, Pathotype 2 at 2000 J2/kg soil significantly decreased plant height and grain yield of fennel cv. PF 35 by 19.83 and 26.51% respectively, while root-knot index and reproduction rate were significantly increased by 59.01 and 58.88 % respectively over control-steam sterilized soil. vi, Application of Dazoraet (Basamid 98 G @ 1 g/pot) significantly increased plant height and grain yield of fennel cv. PF 35 by 18.61 and 36.09 % respectively and root-knot index has significantly, reduced by 59.01 % due to Dazomet application over control-no nematicidal treatment.ThesisItem Open Access STANDARDIZING CONDITIONS FOR PILOT SCALE PRODUCTION AND STORAGE OF BUFFALO SKIM MILK DAHI USING STREPTOCOCCUS THERMOPHILUS: SOME CHEMICAL ASPECTS(AAU, Anand, 1990) Thakuria, Hemanta; Patel, S. M.This investigation was planned and carried out to elucidate the effects of level of total solids of buffalo skim milk and inoculation with three specific strains of Streptococcus thermophilus on some of the quality attributes of dahi. The total solid content of buffalo skim milk was adjusted to 10.0 (T1), 12.5 (T2) and 15.0 (T3) per cent using condensed buffalo skim milk and inoculated with D3(C1), MD2 (C2) and MD8 (C3) strains of Streptococcus thermophilus. Incubation was done at 40 ± 1°C till the desired acidity of 0.75 (% lactic acid) was obtained. Samples were then stored at 5 t o 7°C for about 12 h after which the samples were considered to be at 0 h of storage (fresh product). To study the physico-chemical and organoleptic changes taking place and also to study the shelf - life of the dahi under room temperature, the samples were stored at 37 ± 1°C and analysed at the interval of Oh, 12h, 24h and 48h. Similarly for study under refrigerated condition samples were stored at 5 t o 7°C and analysed at the interval of Od, 6d, 12d and 18d of storage.ThesisItem Open Access CROP WEATHER RELATIONSHIPS AND POPULATION DYNAMICS OF Helicoverpa armigera IN TWO PIGEON PEA (Cajanus cajan L.) CULTIVARS IN MIDDLE GUJARAT AGROCLIMATIC REGION(AAU, Anand, 1996) RAVIPATI, MAHENDRA KUMAR; Savani, M. B.Pigeonpea [Cajanus cajan L.) is one of the major grain legume crop in tropical and sub - tropical regions of India and grown mainly as rainfed crop. The crop is characterised as drought resistant and the productivity is different in different environments. Since the effects of weather on yield are complex, the deep and clear understanding of the effect of weather parameters on the growth and development of pigeonpea is necessary. An experiment was conducted during the Kharif season of the, year 1994 at Anand to study the crop-weather relationship and crop-weather-pest dynamics in two cvs.BDN-2 and GT-100 of pigeonpea. The field experiment was laid out in split plot design with four replications. The treatments comprised of two irrigation levels, two plant protection levels, two varieties, and three dates of sowing. The results obtained during the course of investigation revealed that weather played significant role in growth, development and yield of pigeonpea. The variations in days taken to complete the different phenophases among the different dates of sowing were attributed due to the variations in temperature and photoperiod. The number of days required for the completion of any phenophase was declined with increase in the temperature and photoperiod. The yield and yield attributes were significantly influenced by irrigation and dates of sowing. The grain yield, biomass, and number of pods per plant were observed more in D1 than in D2, and D3. Grain yield, biomass, and number of pods per plant declined with the application of irrigation. The irrigated crop puts up more biomass initially but it was declined considerably than in unirrigated crop in the later phases due to heavy attack of the larvae of Helicoverpa. The different agrometeorological indices like GDD, PTU and HTU has positive and significant correlation with days taken for the completion of the different phenopases, eccept for the phenophase P4. The thermal time (GDD) has highly significant correlations with days taken for different phenophases. Functional relations were developed to predict the number of days required for different phenophases in both the cultivars BDN-2 and GT-100. The leaf area index (LAI) and crop growth rate (CGR) were found to be influenced by irrigation and sowing time. The crop sown in D1 maintained more LAI and CGR in both the cultivars, compared to D2 and D3, The decline in the values of LAI and CGR during flowering phase in both the cultivars was due to heavy infestation of Helicoverpa. The radiation use efficiency (RUE), on seasonal basis was found to be high in rainfed crop compared to irrigated crop. The RUE was high in D1 sown crop, and was declined in the delayed sowings. The RUE was found high in cv.GT-100 compared to cv.BDN-2. Functional relations were developed to estimate the near surface soil moisture content under developing conopics of pigeonpea using remotely sensed canopy and air temperatures, and the LAI. A linear relationship was observed between evapotranspiration and canopy-air temperature differential. The relation was found closely related, when the variations due to energy load was accounted. The populations of the eggs and larvae of the Helicoverpa were found to be highest in first date of sowing (D1) both at 50% flowering and 50% podding phases compared to D2 and D3. The cultivar GT-100 was found more succeptible to Helicoverpa due to the early flowering character than cv.BDN- 2. The larval population of Helicoverpa in pigeonpea was found significantly correlated with air temperature, vapour pressure and pan evaporation.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 A STUDY ON COMMUNICATION GAP BETWEEN EXTENSION WORKERS AND FARMERS WITH A SPECIAL REFERENCE TO PADDY CROP IN THE JIND SUB-DIVISION OF HARYANA STATE(AAU, Anand, 1990) Singh, Prithvi; Patel, H. N.INTRODUCTION: Systematic training and systematic visit are two basic concept incorporated with the T&V Extension System. The main idea behind the systematic training is to develop adequate professional knowledge and skill in extension workers about the specific farm recommendations to be made during the forth coming fortnight to the farmers. Systematic visits to the farmers field and making interpersonal contacts with farmers follow the training. Schedule of visit are closely supervised at all levels of the extension system. The number of farm families per village extension worker is set at a manageable level and specific schedule of visit is rigidly followed. The ratio of supervisory staff is such that close supervision is convenient at all levels.
