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.

    EPIDEMIOLOGY AND MANAGEMENT OF TURCICUM LEAF BLIGHT OF MAIZE CAUSED BY Exserohilum turcicum (Pass.) Leonard and Suggs
    (University of Agricultural Sciences GKVK, Banglore, 2007-08-31) SHARANAPPA I. HARLAPUR; M.S. KULKARNI
    Turcicum leaf blight disease of maize caused by Exserohilum turcicum symptoms were recognised by long spindle shaped necrotic lesions with grey colour centre, immature and chaffy ears. The disease appeared in severe form in most of the maize growing areas of Kamataka. Crop loss estimation studies revealed that, avoidable grain and stover yield losses in susceptible genotype were to the extent of 52 and 40 per cent, respectively. Linear regression crop loss models were developed. Arabhavi isolate recorded high virulence. Sixty-five days old plants found vulnerability to infection. An incubation period of 28 hours was found ideal for more than 90 per cent spore germination. Saccharum arundinaceum Retz. was identified as a potential alternative host to E. turcicum and plays an important role in the epidemiology of TLB in Karnataka. Significantly maximum disease severity was noticed in crop sown on 16^ September. Crop sown between Februaiy and April found least affected. The weather factors, viz., minimum temperature (11.3-21.4®C), maximum temperature (26.3-29.4°C), relative humidity (58.7-84.5%) and rainfall (47.104 mm) were highly favourable for disease epidemic. The locations, viz., Arabhavi, Dharwad, Devihosur, Sankeshwar and Nagenahalli were identified as "hot spots' in Kamataka. Significant and positive correlation existed between rainfall and relative humidity with spore load. The genotypes, viz., Allrounder, IB-8501, Cargill 900M, Hi-Shell, NAC-6004, C-111, KH-517, Kaveri 235 and NK-6240 were identified as slow blighters. The disease was responsible for photosynthesis loss to the extent of 89.40 per cent in susceptible genotype. Fourteen inbrei lines were identified as highly resistant sources. The QPM genotypes HQFM-4 and HQPM-5 found highly resistant. Integration of 'olerant hybrid DMH-2 and seed treatment with carboxin power (2 g/kg) or combined seed treatment with Azospirillum sp. (25 g/kg) and T^choderma harzianum (6 g/kg) followed by three sprays with mancoze? (0.25%) was found to be the most effective IDM package for the management of TLB of maize.

    A CRITICAL ANALYSIS OF ENTREPRENEURIAL BEHAVIOUR OF RURAL AND URBAN WOMEN ENTREPRENEURS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-09-19) SAVITHA, C.M; SIDDARAMAIAH, B. S
    Women as entrepreneur are economically more powerful and contribute to the upliftment of the family. Entrepreneurship is a composite phenomenon which is determined by several factors. The present study was taken up with an objective of measuring the entrepreneurial behaviour of women entrepreneurs in rural and urban areas and to study their characteristics. The investigation also covered the SWOT analysis of EDPs organized by the selected training institutes. The study was carried out utilizing 120 women entrepreneurs from Bangalore (rural) and (urban) districts. A scale was developed to measure the entrepreneurial behaviour of women. Data was analysed with suitable statistical tests The major findings of the study were (i) the entrepreneurial behaviour index of urban women was significantly higher than that of rural women; (ii) the entrepreneurial behaviour of both rural and urban women were positively and significantly related with their education, marital status, birth order, family support, socio-economic status, deffered gratification, socio-political participation, cosmopoliteness, mass-media participation, ownership of enterprise, extent of investment and training received. While it was negatively and significantly related with age and family dependency ratio; (iii) the results of regression indicated that all the 16 variables put together explained 86 percent of the variation in case of rural women entrepreneurs and 98 percent in case of urban women entrepreneurs. Family dependency ratio, mass media participation and financial assistance had made significant contribution to the entrepreneurial behaviour of rural women where in case of urban women family support, cosmopoliteness, institutional support, socio-economic status and financial assistance made significant contributions; (iv) the results of SWOT analysis pointed out that the major strengths of EDP were (a) conducting of need assessment (b) brain storming session (c) developing comprehensive course content; (v) both urban and rural women entrepreneurs experienced several production, financial, marketing and personal constraints while running their enterprise.

    STATUS AND REVALIDATION OF PHOSPHORUS REQUIREMENT FOR FINGER MILLET-MAIZE CROPPING SYSTEM IN SOILS OF EASTERN DRY ZONE OF KARNATAKA
    (University of Agricultural Sciences GKVK, Bangalore, 2014-10-05) CHANDRAKALA, M.; SRINIVASAMURTHY, C. A.
    An investigation on available soil phosphorus status, P fractions, requirement of P for finger millet and maize in EDZ of Karnataka and revalidation of soil test ratings for phosphorus was taken at UAS, Bangalore. Soil samples from EDZ were analysed for P status and randomly collected samples were analysed for P fractions. Response of finger millet and maize to graded levels of P was studied in the field by creating five phosphorus fertility gradients viz., P0 (Very low), P1 (Low), P2 (Medium), P3 (High) and P4 (Very high) (< 15: 16-30: 31-45: 46-60: > 60 kg P2O5 ha-1, respectively). Critical limits and soil P ratings was determined by conducting pot culture experiment in 24 soils from six different locations from each VL, L, M and H categories, using maize as test crop applied with graded levels of P. Results revealed that, application of 125% RDP with rec. NK&FYM recorded higher finger millet (31.66 and 55.32 q ha-1grain and straw, respectively) and maize (78.26 q ha-1 grain) yield in high P strip. PUE was higher with lower levels of P application. There was a build-up of P in soil with graded levels of P application to gradient strips, which was reflected by increase in total P and P fractions. Critical limit for available P2O5 was 17.00 kg ha-1 and for plant 0.12 per cent. The proposed fertility ratings for available P2O5 are <15.50, 15.51-28.00, 28.10-48.50 and >48.50 kg ha-1; VL: L: M: H, respectively. Available P2O5 in soils of EDZ ranged 10.22 to 98.32 kg ha-1. Percentage of soil samples under different category are Low (30.80) > Medium (27.20) > High (21.20) > Very low (20.80). Total-P, organic-P, reductant soluble-P, occluded-P and Ca-P increased as the soil phosphorus fertility increased and reverse trend was noticed for saloid-P, Al-P and Fe-P fractions.
