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.

    PRUNING PRACTICES FOR MAXIMIZATION OF MULBERRY LEAF PRODUCTIVITY UNDER UAS SERI SUVARNA TECHNOLOGY AND REARING PERFORMANCE IN RAINFED CONDITION
    (University of Agricultural Sciences GKVK, Banglore, 2007-09-17) R. LAKSHMINARASIMAPPA; Dr. K.P. CHINNASWAMY
    Field experiment was carried out to investigate the effect of pruning practices for maximization of mulberry leaf productivity under UAS Seri Suvama technology on growth and yield of Ms mulberry variety and the silkworm B. mori L. in relation to rearing performance in rainfed condition at Department of Sericulture, UAS, GKVK, Bangalore during the year 2004-05. The results indicated that mulberry growth parameter viz., number of branches and leaves, leaf yield, leaf moisture, chlorophyll a, b content, total chlorophyll content, total soluble sugar and protein content NPK, Ca, Mg and S content were influenced by the pruning practices. However, pruned crop shows 90 cm height more / higher of all the above parameters which is followed by pruning at 60 cm, 30 cm bottom pruning, 90, 60 and 30 cm with normal shoots as compared to non-UAS Seri Suvarna. Similarly, the soil moisture content at 60 cm depth and soil arthropods populations like beetles, grubs, termites, centipedes and earthworm were higher in treatment of 90 cm height pruned plots as compared to other treatment. The larval weight cocoon weight, growth rate, shell weight, shell percentage, silk productivity and ERR percentage and silk filament was also higher in 90 cm height, pruned plots, which is followed by 60, 30 cm bottom pruning 90, 60, 30 cm height with normal shoots compared to non-UAS Seri- Suvama. The instar duration larval duration, silk denier and disease incidence was less in 90 cm height pruned plot as compared to other treatment. Similarly, benefit cost ratio 90 cm height pruned crop was 5 : 73 which is followed by 5:11 and 5 : 07 in 60 and 30 cm height pruned plot respectively, the lowest B:C ratio of 1 : 92 was obtained in non-UAS Seri Suvarna technology

    OVIPOSITIONAL DETERRENT EFFECT OF EUCALYPTUS CITRIODORA HOOK. AGAINST INDIAN UZI FLY AND ITS IMPACT ON GROWTH AND DEVELOPMENT OF MULBERRY SILKWORM
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-08-28) GAYATHRI DEVI, S; NARAYANASWAMY, K.C
    A laboratory experiment was conducted to study the ovipositional deterrent effect of Eucalyptus citriodora Hook.agalnst Indian uzi fly and its impact on growth and development of mulberry silkworm. The extent of reduction in oviposition rate of uzi fly was 87.59, 86.90 and 85.58 per cent over the control after 24, 48 and 72 hours after application of 10 per cent leaf powder of E.citriodora on silkworms on second third and fourth day of fifth instar, respectively. The food consumption (791.19g), digestion (580.29g), consumption index (1.37), growth rate (0.027), approximate digestibility (81.15), efficiency of conversion of ingested food (2.66), efficiency of conversion of digested food (2.86) and reference ratio (4.61) were significantly maximum when 10 per cent leaf powder of E.citriodora was dusted over silkworms on second, third and fourth day of fifth instar. Similar trend was also observed in respect of 10 per cent aqueous leaf extract of E.citriodora. However, the consumption indices were superior in silkworms treated with leaf powders as compared to those treated with aqueous leaf extracts of E.citriodora. Leaf powder of E.citriodora at 10 (1.50%) and 6 per cent (3.84%) and aqueous leaf extract at 10 per cent were most effective in bringing down the mortality (5.00%) of larvae compared to that of absolute control (12.50%). The larval weight (16.13g/10 larvae), cocoon weight (14.29g/10), shell weight (0.27g), shell ratio (17.15%) and silk filament length (644.30m) were significantly maximum, besides reduction in larval duration when 10 per cent leaf powder of E.citriodora was dusted over silkworms during fifth instar. It is concluded that the 10 per cent leaf powder of E.citriodora is effective in reducing the oviposition rate of uzi fly by acting as oviposition deterrent, besides enhancing the food consumption indices and economic traits of silkworm (PM x CSR2).

    CROSS INFECTIVITY OF PATHOGENS OF DIAPHANIA PULVERULENTALIS (HAMPSON) TO BOMBYXMORIL.
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-08-02) Kumari Mamatha, B.R; NARAYANASWAMY, K.C
    Fortnightly survey was conducted in three villages of Sidlagatta Taluk of Kolar District in Karnataka from August 2006 to February 2007 to record the incidents of leafroller, Diaphania pulverulentalis (Hampson) on mulberry and also the incidents of its diseases. The seasonal incidence and rate of infestation of D. pulverulentalis were significantly maximum during January (91.00 and 18.87% , respectively). The incidence of pathogens of D. pulverulentalis such as, Beauveria bassiana (Bals.) Vuillernen and Aspergillus sp. was noticed from October to January, while the other two pathogens, Microsporidian and DpNPV were prevalent from August to February. The ET50 for expression of symptoms and ET50 for mortality in the test population of B. mori were maximum in silkworms inoculated with 10-2 dilution of B. bassiana, Aspergillus sp. and Microsporidian, but decreased as the dilutions increased. However, no disease expression or mortality were observed in silkworms infected with DpNPV. The silkworms infected with the NPV isolated from caterpillars of D. pulverulentalis performed as those of control batches with regard to larval parameters [viz., fourth larval duration(98.00h), fourth moult duration (25.33h), rate of fourth moult (100%), duration of fifth instar (168 .00h) , fourth and fifth instar larval weight (0.90g and 2.35g , respectively)], cocoon parameters [viz., rate of cocoon spinning (l00%), cocoon weight (1.74g), pupal weight (1.46g)] and post cocoon parameters [viz., shell weight (0.28g) , shell ratio (16 .27%) , silk productivity (3.95cg/day)] and grainage parameters [viz., pupation rate (100%), rate of moth emergence (l00%), cocoons to layings ratio (71.33%) and fecundity (440.33 eggs/moth)] , indicating specificity of DpNPV. However, the economic traits of silkworms were significantly affected when infected with B. bassiana, Aspergillus sp. and Microsporidian, which were isolated from the caterpillars of D. pulverulentalis. Hence, the DpNPV can be evaluated and . utilize

    RESPOniSE OF V-1 HYBRID RAISED ON BLACK SOILS TO APPLICATION OF GRADED LEVELS OF NITROGEN AND THEIR EFFECT ON Bombyxmoril.
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-01-06) MUNIREDDY; PATIL, R.R
    A study was conducted at Main Research Station, Dharwad during 2002-04 under irrigated conditions to study the "Response of V-1 mulberry hybrid raised on black soils to application of graded levels of Nitrogen and in turn their effect on Bombyx mori L." There were eight treatments laid out in a randomized complete block design with three replications. Among the graded levels, application of 280 to 300 kg N was significantly superior to all other treatments with respect to 100-leaf weight (299.72 and 272.22 g/plant), leaf and shoot yield per plant (475.83 and 458.05 and 346.66 and 334.44 g/plant), leaf and shoot yield per crop (8.46 and 8.14 t and 9.36 and 9.14 t/ha/crop) at 60^^ day after pruning respectively. Similar to leaf yield, 280 and 300 kg N recorded significantly maximum relative water content (81.89 and 78.59%, leaf nitrogen (4.42 and 4 44%j and crude protein (27.76 and 26.53%) except moisture, chlorophyll a, b and total chlorophyll and sugar contents as compared to standard (350 kg N) and untreated check. Among the different order of leaves, tender leaves recorded maximum total nitrogen Eind crude protein compared to medium and coarse leaves. Chlorophyll a, b and total chlorophyll content and sugar contents were higher in middle leaves. Coarse leaves recorded higher relative water content but low moisture content. 280 and 300 kg N registered maximum chawki (3.51 and 3.33 g), mature larval weight (34.72 and 34.22 g), silk gland weight (1.70 and 1.59 g), lower disease incidence (7.10 and 10.58%) and ERR (92.95 and 89.38^). It was interesting to note that 280 kg N and 150 kg N + 2.5 t VC recorded higher cocoon yield of 16.46 and 16.47 kg per 10,000 larvae as compared to standard (350 kg N) and untreated check respectively. Among the rearing seasons, rainy season was the best and recorded lower disease incidence (8.38%) and maximum ERR (91.70%) as compared to winter and summer seasons. Application of 280 kg N during rainy season was significantly superior to mature larval weight, cocoon weight, pupal weight and shell weight.
