University of Agricultural Sciences, Bengaluru
University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

ThesisItem Open Access ECOFRIENDLY APPROACHES FOR THE MANAGEMENT OF Spodoptera litura (F.) IN GROUNDNUT(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-06) PATIL, RAJASHEKARH K.; HIREMATH, I. G.Ecofriendly methods for the effective management of Spodoptera litura in groundnut were studied during 1996 to 1998 at Main Research Station, UAS, Dharwad. The EIL computed for third instar larvae of S. iitura at flowering (30 DAS), peg formation (45 DAS) and pod development (60 DAS) stages was 1.04, 2.18 and 3.59 larvae per plant. At the corresponding stage, the egg load required to cause economic damage was 1.32, 2.90 and 8.74 egg masses per 7.5 m^ or 25 m row, respectively. Annona squamosa, NSKE (5%) and AUium sativum (5%) exhibited good ovicide. property causing around 30 per cent mortality as compared to cent per cent in rr.ethomyl in vitro. The aqueous extract of NSKE (5%), Vitex negundo and A. squamosa caused more than 52 per cent mortality in neonate larvae. Among various comcinations of plant products, NSKE + SINPV, V. negundo + SINPV, NSKE + Nomuraea rileyi and V. negundo + N. riieyi qtoved equally as recommended insecticides "n reducing damage and recording higher yield with better B:C ratios. Vitex negundo and A. mexicana in combination with monocrotophos (0.025%) and V. negundo followed by monocrotophos (0.05%) recorded equal yield compared to recommended package. The entomopathogenic fungus, N. /■/Vey/occurred in epizootic form on S. iitura in groundnut during the rainy season. Persistence of N. rileyi on groundnut foliage during kharif v/as upto ten days. In vitro studies on compatibility of entomopathogen with fungicices, insecticides and botanicals indicated that fungicides were highly detrimental followed by insecticides and plant products. Soil application of the pathogen @ 2.5 x 10 12 conidia per ha followed by foliar spray (S 1.2 x 10 11 conidia per ha follov.ed by spraying monocrotophos (0.05%) mixed with cyperconazole (0.1%) were :he most effective combined applications.

G.; RANGANATHASASTRY, K.N.Kamataka is leading in mulberry silk production. The focus of the study was on economic analysis of silk reeling units. Multistage sampling procedure was adopted and totally 25(f samples were selected. Relevant data collected from primary and secondary sources were analysed through tabular, cluster, orthogonal polynomial regression, log-linear regression, frontier function and decomposition techniques. The growth anafysis of charka and cottage basins in Kamataka showed an increasing trend upto 1996, then onwards showed declining trend. Charka and cottage basins in Bangalore and Kolar districts exhibited constant increasing tr^end. Mysore district showed a unique pattem of declining trend in the later part of 1990s. Renditta was 8.82, 9.57 and 9.02 kg in charka, cottage and multi-end basins respectively. The share of cocoon cost to the total cost was >85 per cent in these systems. Sources of fuel used in reeling were neither eco-friendly nor cost effective. Net retums per kg of silk reeled were Rs.47.21, Rs.146.18 and Rs. 185.28 in these systems, respectively. Medium charkas (4-5limit) and cottage basins (6-8/unit) were found optimum. The proportion of women labour used was more in all the systems. Labour employed per kg of silk reeled was 1.07, 1.45 and 1.34 man-days in charka, cottage and multi-end basins, respectively. The value addition (72.18%) in cottage basin reeling over charkas was mainly due to technique of reeling (57.56%) and the remaining attributed for the use of inputs (14.62%). The package for introduction of silk reeling in new sericulture area suffers from lack of skilled labour, infrastructure, financial support and correct information about the programmes. The conditions imder which children worked were most pathetic. Present laws and their efficiency of implementation have not solved the problem of child and women labour exploitation, hence needs the thorough investigation.ThesisItem Open Access GENETIC ANALYSIS OF HEAT AND DROUGHT TOLERANCE IN TETRAPLOID WHEAT(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-07) RUDRA NAIK, V.; Hanchinal, Dr. R. R.ThesisItem Open Access IN VESTIGATIONS ON THE SHOTHOLE BORER, Xyleboriisperforans (Wollastan) (Coleoptera : Scolytidae) ON POMEGRANATE(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-06) JAGGINAVAR, S. B.; KRISHNA NAIK, L.Shothole borer infesting pomegranate was identified as Xyleborus perforans (Coleoptera : Scolytidae). The insect was noticed in all the gardens surveyed irrespective of source of varieties, type of soil and irrigation systems followed by the farmers. The per cent pomegranate plant wilting at northern Karnataka districts were ranged from 11.33 to 47.20 at Bagalkot, 11.22 to 29.68 at Bijapur, 2.00 to 6.66 at Belgaum, 4.48 to 8.13 at Koppal, 2.66 to 5.46 at Bellary. 2.28 to 5.60 at Raichur and 0.17 at Gulbarga. The plant wilting without shothole borer incidence was observed in the gardens less than 3 years age and ranged from 0.0 to 3.57 per cent as evidenced by the presence of the fungus, Verticillium sp. The correlation between age of the plant and total number of shotholes indicated significantly positive relationship. The external visible symptoms of infestation comprised of yellowing, followed by sudden drooping of leaves and ultimate death of the plants. The whitish yellow powder was seen comingout of the bored holes at the base of stem. In freshly infested plants, the powdery material was pushed out from the bored holes by the beetle which appeared like "burnt inscent stick". Further, around the bored holes blackening of tissues were seen and the holes were in the horizontal plane of the entrance tunnels. The shotholes were often crowded at the collar region of the stem towards the shaded sides and the number declined towards the apical side. The density of immature stages and adults were maximum on primary roots followed by stem hidden in the ground and secondary roots whereas it was maximum at the collar region of the pomegranate plant. The per cent plant drying due to shothole borer incidence with vascular tissues -discolouration,-was observed throughout the year. Maximum wilting of pomegranate plants were observed in the month of August to November and peak active shotholes (5.26) were in November month. Of the 19 pesticides applied as preventive control measures, drenching with chlorpyriphos (3 ml/I) + carbendazim (1 g/l), carbaryl (6 g/l) + carbendazim (1 g/l), monocrotophos (1.5 ml/I) + carbendazim (1 g/l) and quinalphos (2.5 ml/1) + carbendazim (1 g/l) were found as best treatments during Ambe and Mrig bahars by recording higher reduction in percent live shotholes and higher fruit yield without death of the plant at harvest. Of the 12 pesticides applied as curative measures, drenching with chlorpyriphos ; 3 ml/1) + carbendazim (1 g/l) and monocrotophos (1.5 ml/1) + carbendazim (1 g/l) emerged as the best treatments in recording, respectively 92.08 and 77.23 (Ambe bahar), 97.58 and 87.61 n Mrig bahar) per cent reduction in live shotholes. increased fruit weight, fruit number and absolutely no death of plants was seen till the harvest of fruits.ThesisItem Open Access STUDIES ON THE MANAGEMENT OF SERPENTINE LEAF MINER, Liriomyza trifolii(Burgess) (DIPTERA : AGROMYZIDAE) ON COTTON(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-06) NADAGOUDA, SUSHILA; PATIL, B. V.Studies undertaken on the nmnagenient of serpentine leaf miner Lirioniyza trifolii on cotton during 1997-98 and 1998-99 season revealed that cotton plants infested from sowing time and plants exposed for infestation from 10 and 20 DAS recorded significantly higher percentage of infestation which resulted in vegetative and reproductive growth loss. Early stage (upto 20 days) infestation of SLM resulted in a loss of 45.75 per cent. Studies on host plant resistance revealed that G. arhoreiun and G. herbaceuin genotypes recorded significantly lower incidence and maggot population of SLM compared to G. hirxutuin , G. barhadence and hybrids. Less preference of some genotypes was beciurse ofpresence of small thin lobed leaves, higher number of trichomes, less amount of proteins and reducing sugars. Sensitivity studies indicated that among the four locations the maggots collected from kasbe camp(high pesticide impo.scd area) were less .sensitive to all the in.secticides. Imidacloprid was superior over all the insecticides in inducing the mortality of maggots. The LC50 value was highest in maggots collected from kasbe camp for all the insecticides which varied froin 0.2356 to 0.5463 g per litre in cotton being highest to endosulfan and lowest to cypermethrin. Highest resistance ratio of 25.72 and 18.17 folds was recorded in Kasbe camp and RRS cultures respectively to cypermethrin. The LC50 of ad.ult L. trifolii collected from Kasbe camp varied from 0.39456 to 2.10670 |ig per ml.All the Irealments with castor trap crop recorded sgnificanlly lower incidence of SLM and among them castor sown inbetween two cotton plants recorded significantly lowest incidence and highest seed cotton yield . Seed treatment with imidacloprid 70 WS at 15g/kg of seeds resulted in significant reduction in incidence and maggot population upto 17 DAS . Incidence of SLM was significantly lower in biointensive IPM module(M-l) and after lODAS it performed on par with adoptable IPM molule {M-2) & it was highest inRPP module (M-3). All the three modules did not exhibit any significant difference in recording the seed cotton yield. Anlaysis of cost effectiveness of modules revealed higher licnefits from adoptable 1PM module followed by biointensive 1PM module and it was least in recommended pakage of practicesThesisItem Open Access EFFECT OF ORGANIC, INORGANIC FERTILIZERS AND In situ VERMICULTURE ON GROWTH AND FLOWER YIELD OF JASMINE(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-03) PATIL, SATEESH R.; Sathyanarayana Reddy, Dr. B.A field experiment was carried out at the Floriculture Unit of Kittur Rani Channamma College of Horticulture, Arabhavi, University of Agriculture Sciences,Dharwad during 1996-97 and 1997-98, to study the effect of organic,inorganic and in situ vermiculture on growth and flower yield of Jasmine. To achieve the objectives of the study, two separate experiments were carried out. In the first experiment, all the growth components of Jasminum sambac Ait. were better in the plants supplied with 50 per cent RDF along with vermicompost (2 or 4 or 8 kg/plant) and RDF + RDFYM (120:240:240 g NPK + 20 kg FYM/plant). The plants supplied with vermicompost alone (2 or 4 or 8 kg/plant) or in combination with 50 per cent RDF were early to initiate flowering. Good quality flower buds were produced by the plants which received 50 per cent RDF + Vermicompost (2 or 4 or 8 kg/plant) and in situ vermiculture (50 or 100 worms/plant) and RDF + RDFYM. The ftower yield was maximum in the plants which received RDF -I- RDFYM and 50 per cent RDF + vermicompost (2,4 or 8 kg per plant). In the second experiment, the growth parameters which were influenced mostly by N were optimum in lower levels of N, but luxur-iant in higher levels at the cost of flowering. The nutrient combination of 60:120:120 of per plant of NPK along with 20 kg FYM per plant was found optimum to achieve the optimum growth and flower yields in the first two years of planting in Jasminum auricuiatum Vahl.
