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.

    STUDIES ON VARIABILITY GENERATED BY COMBINATION OF HYBRIDIZATION AND INDUCED MUTATION IN GROUNDNUT {Arachis hypogaeu L.) NAGARAJ P.
    (University of Agricultural Sciences GKVK, Bangalore, 2005-07-07) NAGARAJ, P.; P.V: KENCHANAGOUDAR
    A field experiment was undertaken at the Main Agricultural Research Station, Dharwad 4uring the kharif season of 2002-03 and at the Agricultural Research Station, Arabhavi during summer 2003-04 to compare the efficiency of direct hybridization followed by mutagenesis to release additional genetic variability, frequency of desirable segregants and to study shift in character associations between the two comparative populations. A set of three crosses involving four genotypes (GPBD-4, lCGV-86252, VG-9521 and ICGV-86699) formed the base material for this study. Half the quantity of Fi seeds of each of the three crosses were treated with EMS (0.5%) and remaining half quantity was advanced as such. The study revealed an increase in variability of traits as a result of hybridization with mutagenesis as compared to hybridization alone. The highest phenotypic and genotypic coefficients of variability were observed for the characters like plant height, numbers of primary branches, number of pods per plant, pod yield per plant, kernel yield per plant, 100-kernel weight and rust severity score. Mutagen treated populations gave relatively higher percentage of superior segregants for pod yield (20.83%), disease (rust) resistance (7.33%), SMK percentage (41.57%) and shelling percentage (14.33%) as compared to untreated population (16.50%, 5.67%, 40.50% and 11.33%, respectively). EMS treated population also produced higher population of superior recombinants for combination of pod yield, disease resistance, shelling percentage and SMK percentage (1%) as compared to untreated population (0.33%) in Fa generation. Correlation studies in F3M3 generation revealed shift in association towards the desirable side in respect of pod yield with shelling percentage and kernel yield with shelling percentage in the cross GPBD-4 x ICGV- 86252 and pod yield with shelling percentage in both VG-9521 x ICGV- 86252 and VG-9521 x ICGV-86699 crosses. Thus, hybridization followed by mutagenesis in the present study showed promise for not only increasing the variability but also to increase the frequency of desirable transgressive segregants and to bring the shift in direction of association between different character pairs in the desired direction.

    A STUDY ON KNOWLEDGE AND ADOPTION OF IMPROVED CULTIVATION PRACTICES BY MANGO GROWERS OF NORTH KARNATAKA
    (University of Agricultural Sciences GKVK, Banglore, 2005-06-17) MOULASAB, I.; K. A. JAHAGIRDAR
    The study was carried out in Dharwad and Belgaum districts of North Karnataka during the year 2003-04. Following the simple random sampling, 120 respondents were selected from six villages of two taluks. The data was elicited through personal interview method. The important findings of the study were; majority of the respondents possessed medium level of knowledge (72.50%) and adoption (68.33%) about improved cultivation practices of mango. Almost all the mango grower had grown Alphonso and Totapuri varieties. More than half the number of mango growers had followed the recommended spacing, irrigation for young gardens and applied different chemicals for the control of the mango hopper and the powdeiy mildew disease.

    EVALUATION OF ORGANICS AND INOIGENOUS PRODUCTS FOR THE MANAGEMENT OF HelwoverpaamilBera{M\im) IN CHILLI
    (University of Agricultural Sciences GKVK, Banglore, 2005-07-04) RAVIKUMAR; K. BASAVANA, GOUDA
    A field trail was carried out using chilli var. Byadagi Dyavanoor during kharif season of 2002-03 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to evaluate the organic amendments and indigenous products for the management of H. armigera. Studies on the effect of organic amendments on H. armigera revealed that among the different organic amendments, soil application of neem cake @ 1 t/ha was very effective in recording lowest eggs (0.69), larval population (0.62) and lowest fruit damage (6.5%) being on par with vermicompost @ 2 t/ha. Next best treatments were neem cake @ 0.5 t/ha + 50 per cent RDF, vermicompost @ 1 t/ha + 50 per cent RDF and RDF. Neem cake @ 1 t/ha recorded highest green chilli yield of 83.47 q/ha being on par with RDF (79.00 q/ha) and RPP (89.33 q/ha). These were followed by vermicompost @ 2 t/ha + 50 per cent RDF (76.00 q/ha) and neem cake @ 0.5 t/ha + 50% RDF (72.00 q/ha). Highest B;C ratio of 3.88 was noticed in neem cake @ 1 t/ha from among the organic amendments evaluated
