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.

    SUSTAINABLE PRODUCTIVITY OF MAIZE - SOYBEAN CROPPING SEQUENCE THROUGH INM PRACTICES UNDER IRRIGATED CONDITION IN ALFISOL
    (University of Agricultural Sciences, Bangalore, 2010-02-21) RANAJEET, L. JADHAV; KRISHNAMURTHY, N.
    Field investigation was carried out at GKVK, UAS, Bangalore. The experiment was laid out in a RCBD for maize during K h o rif - 2002 with 10 treatments replicated thrice and in succeeding seasons the experiment was laid out in a split- plot design by taking treatment plots o f kharif maize as main plot treatments. Each of these main plots were divided into two sub plots, the experimental period included kharif - 20 0 2 (maize) - rabi - 2002 (soybean)- summer-2003 (maize)- kharif- 2003 (soybean). Cropping system as repeated on sandy loam soil in a fixed site to study the “Sustainable productivity o f maize - soybean cropping sequence through TNM practices under irrigated condition in alfisol” . The result revealed that during k h a r if- 2002 and summer - 2003 application o f 100 RDF (150:75:40 kg, N:P2 0 s:K.20 ha ) along with enriched compost ( 1.0 t ha' 1 ) significantly higher grain yield o f maize (64.85 and 51.06 q ha'1) blit was on par with 100 per cent with RDF + FYM (10 t ha'1) (60.51 and 48.38 q ha' 1 respectively ) and were significantly superior over 100 per cent RDF + V.C (5.0 t h a '1) (54.70 q ha'1) and 100 per cent RDF alone (48.34 q ha' 1 and 41.45 q ha'1, respectively during kharif- 2002 and summer - 2003). This was attributed to significantly higher values o f growth and yield components. Application o f 100 per cent RDF + V.C (5.0 t ha"1) in combination to preceding maize resulted in higher seed yield o f soybean (18.78 and 20.35 q ha'1) and haulm yield (3.11 and 3.23 t ha'1) respectively of succeeding rabi 2002 and kharif- 2003 soybean. It was supported by growth and yield parameters. Integrated use o f organics along with RDF to maize improved soil physico- chemical i.e., O.C., F.C PWP and NPK etc., and biological properties viz., soil bacterial, fungi, and actinomycetes population in soil. Application o f 100 per cent RDF+FYM (10 t ha'1) to maize and 50 per cent RDF to soybean is the best to get higher B:C ratio (Rs.3.30) for low income farmers but where finance is not limiting such farmers can increase fertilizer up to 100 per cent RDF to soybean (Rs.3.42). Application o f 100 per cent RDF+FYM or EC or V.C or 50 per cent RDF+EC+ Azospirilhm to kharif- 2002 maize and summer 2003 and growing o f Soybean in sequence during rabi - 2002 and kh a rif - 2003 with 50 per cent RDF gave higher maize equivalent yield, net returns, B:C ratio and sustained soil fertility, Thus from the study, it revealed that integrated use o f organic and inorganic source o f nutrients are better for production and maintenance soil fertility.

    DEVELOPMENT OF TRANSGENIC TOMATO AGAINST SPOTTED WILT DISEASE CAUSED BY PEANUT BUD NECROSIS VIRUS (PBNV)
    (University of Agricultural Sciences GKVK, Bangalore, 2010-08-31) MAHESHA, B.; Ranagaswamy, K. T.
    Tomato is an important warm season vegetable crop of the world, India and Karnataka. It belongs to the family Solanaceae. Among the viral diseases spotted wilt caused by Peanut bud necrosis virus is the major one by threatening the crop in severe form with a yield loss of up to 90%. Since the conventional management practices of this disease is not satisfactory, management through genetic approach will be beneficial. This is achieved through incorporation of PBNV-NP gene into the genome of the tomato (NSPLT-1) by in planta method of transformation. Transformation of tomato (NSPLT-1) with PBNV-NP gene by in planta method was followed. Totally 55 T0 plants were able to established well and collected the seeds from them individually. Further, they were evaluated by Kanamycin screening at preliminary level, DAC-ELISA and PCR analysis. Results confirmed that few plants showed positive for presence of PBNV-NP gene. Because of lower population of positive plants, they were multiplied by tissue culture and micro propagation method. But those plants were not carried out for further generation because they were phenotypically not good. Hence, raised the nursery without Kanamycin screening by using 5 T0 events. From each event 10 seedlings were selected and allowed to grow the T1 population. Further, evaluated T1 population (Without Kanamycin screened) by DAC-ELISA and PCR analysis by using gene specific antiserum and primers respectively. Based on the DAC-ELISA and PCR analysis positive plants were selected and carried out to T2 generation. In this generation 35 plants confirmed the presence of gene of interest (PBNV-NP). Out of 35 plants 5 best events were selected based on DAC-ELISA, PCR and Nested PCR data for mRNA extraction, synthesized the cDNA and conducted the RTPCR analysis. The results revealed that expression of protein synthesis in all the selected events. Further T2 positive plants were subjected for bio assay by challenging with PBNV inoculum and the results confirmed the PBNV-NP gene integration in tomato plants and which conferred the resistance in inoculated plants.

    ISOLATION AND CHARACTERIZATION OF POTASH SOLUBILIZING BACTERIAL AND FUNGAL INOCULANTS ON GROWTH AND YIELD OF POTASH RESPONSIVE CROPS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2010-02) REKHA, R; Sreeramulu, K R
    Potassium is the third major plant nutrient required for the plant growth. In soils grown with crops like paddy, ragi, maize, sorghum, sunflower the straw and stubbles left out in the field contains large amount of silica which combines with potassium present in soil and get fixed as potassium silicate or calcium or magnesium silicate and become unavailable to plant growth. There are certain bacteria and fungi which are capable of solubilizing the bound form of potassium by secreting organic acids and helps in mobilization of potassium in soil and made it available for the plant growth. In this context an attempt was made in this study to isolate an efficient potash solubilizing bacteria and fungi by soil enrichment technique and characterized by in vitro studies and the efficient potash solubilizers were identified. The two efficient bacteria identified were Bacillus mucilaginosus (UASKB 102) and Pseudomonas fluorescens (UASKB101). Similarly the two fungal isolates which were selected as efficient potash solubilizers are Aspergillus niger (UASKF102) and Aspergillus terreus. (UASKF101). The efficiencies of these selected strains were further tested under field conditions on high potassium required crops like tobacco and potato. Field evaluation studies conducted during Rabi-Summer 2006-2007 on tobacco at RRS, Navile, Shimoga and on potato at ARS, Madenur, Hassan Dist. showed that in both the crops plants supplemented with 75% or 50% NPK with A. chroococcum + B.subtilis with isolated potash solubilizing fungi UAS KF102 ( Aspergillus niger ) performed best in improving the plant growth attributes and crops yields followed by 75% or 50% NPK + Azotobacter chroococcum + Bacillus subtilis + UASKF 101 (Aspergillus terreus). Among the bacterial isolates 75% or 50% NPK with Azotobacter chroococcum + Bacillus subtilis + UASKB 102 (Bacillus mucilaginosus) followed by 75% or 50% NPK with Azotobacter chroococcum + Bacillus subtilis + UASKB 101(Pseudomonas fluorescens) has improved the crop growth and yield. The consortial application has showed enhanced plant nutrient uptake, residual NPK status of soil after crop harvest and improved the soil microflora. The results also showed that fungal cultures were more efficient than bacterial cultures in solubilization of Potassium. The research results of field studies have clearly showed that in both tobacco and potato a net saving of 25% NPK is possible with maximum crop yield when consortial application of an efficient N2 fixer, P and K solubilizer was used in crop cultivation.

    CRITICAL ANALYSIS OF TRIBAL DEVELOPMENT PROGRAMMES IN WESTERN GHATS OF SOUTH INDIA
    (University of Agricultural Sciences GKVK, Bangalore, 2010-05-06) ARULARASAN, G. S.; NARAYANA SWAMY, B. K.
    The study was conducted to analyse the effectiveness of Integrated Tribal Development Programme (ITDP) at individual and community levels in Nilgiri Biosphere Reserve. The Primitive Tribal Group ‘Kattunaickens’ were the respondents and 150 respondents selected using multistage random sampling constituted population for the study. At individual level, there were high levels of impact in literacy, demographic factors, socio-economic status and food and nutritional security, as opined by 44, 42, 41.33 and 43.34 per cent of the respondents, respectively. Agricultural productivity, allied enterprises and increase in employment were at medium levels, according to 40, 39.33 and 42.67 per cent of the respondents. At community level, 51.33, 53.33 and 45.33 per cent perceived that there were medium levels of improvement in basic amenities, transport and communication and finance and industries, respectively. 49.33, 56 and 58.67 per cent felt that socio-political sovereignty, cultural compatibility and ecological protection were at low levels. Correlation coefficient analysis showed significant relation between interdependent variables and effectiveness. The variables education, farm size, social participation, economic motivation, value orientation, achievement motivation, scientific orientation and benefits accrued were positively correlated at individual level; while farm size, annual income, economic motivation, value orientation, achievement motivation, risk orientation, decision making ability and benefits accrued were positively correlated at community level. The independent variables contributed for 52.10 per cent to the effectiveness at individual level and 62.60 per cent at community level in Karnataka, 61.80 and 71.80 per cent in Kerala and 67.40 and 68.40 per cent in Tamil Nadu. Strong sense of ‘we feeling’ (92%) was the main factor that contributed for the success of tribal development programmes. The SWOT analysis of ITDP showed that main strength was the holistic approach (93.33%), prime weakness was lack of coordination (92%). Human resource development was the key opportunity (96%) and major threat was non-willingness of the Government personnel to work in remote areas (94.67%). The model for sustainable tribal development included seven dimensions: educational empowerment, credible political will, economic sustainability, technological empowerment, social equity, cultural compatibility and environmental health.
