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.

    INFLUENCE OF PLANTING GEOMETRY AND NUTRIENT LEVELS ON GROWTH AND PRODUCTIVITY OF BLACKGRAM (Vigna mungo L.)
    (University of Agricultural Sciences, Bangalore, 2023-02-16) DEVINDRAPPA; P. PRAKASH
    “A field experiment entitled influence of planting geometry and nutrient levels growth and productivity of Blackgram (Vigna mungo ” was conducted during Kharif 2021, at ZARS, University of Agricultural Sciences, Bangalore. The experiment was laid out in Factorial Randomized Complete Block Design with two factors viz., spacing and nutrient levels both at four different levels and were replicated thrice. Spacing levels comprised of S1: 30 × 10 cm, S2: 45 × 10 cm, S3: 30 × 15 cm and S4: 45 × 15 cm. Nutrient levels comprised of F1: 75% RDF, F2: 100% RDF, F3: 125% RDF and F4: 150% RDF. Recommended dose of fertilizer followed in the experiment was 25:50:25 kg NPK ha-1. The results revealed that spacing of 30× 10 cm (S1) recorded significantly higher seed yield (1077 kg ha-1), net returns (Rs. 49089ha-1) and B:C ratio (3.3) compared to other spacings. Among the fertilizer levels, significantly higher seed yield (990 kg ha-1), net returns (Rs. 43043 ha-1) and B:C ratio (3.0) was recorded in 150% RDF (F4) which was found on par with 125% RDF (F3). Whereas, higher seed yield (1251 kg ha-1), net returns (Rs. 59746 ha-1) and B:C ratio (3.8) were recorded in treatment combination S1F4 (30 × 10 cm spacing with 150% RDF). Hence, for higher yield and monetary returns a spacing of 30 × 10 cm along with 125% of RDF is found advantageous and profitable.

    SENSOR BASED IRRIGATION AND NANO NUTRIENT MANAGEMENT IN GROUNDNUT (Arachis hypogaea L.)
    (2023-01-31) USHA, H. R.; SUJITH, G.M.
    A field experiment on Sensor based irrigation and nano nutrient management in Groundnut was carried out during summer-2022 at L block, ZARS, GKVK, Bengaluru. The treatments included three irrigation management techniques in main plots (Drip irrigation as per UASB PoP, Sensor based automated drip irrigation at 50% DASM, Sensor based automated drip irrigation at 75% DASM) and five nutrient management practices in sub plots (Absolute control,100% RDF, foliar spray of nano urea @ 2ml litre-1 at 30 and 60 DAS, foliar spray of nano urea and DAP @ 2ml litre-1 at 30 and 60 DAS and foliar spray of nano urea, DAP and zinc @ 2ml litre-1 at 30 and 60 DAS) replicated thrice in split plot design. The results indicated that, sensor based drip irrigation at 50% DASM recorded significantly higher pod yield (1831 kg ha-1), haulm yield (2211 kg ha-1), gross returns (Rs.164790 ha-1), net returns (Rs.87155 ha-1) and B:C ratio (2.12). Among nutrient management, foliar spray of nano urea, DAP and Zinc at 30 and 60 DAS recorded significantly higher pod yield (2152 kg ha-1), haulm yield (2549 kg ha-1), gross returns (Rs.193680 ha-1), net returns (Rs.122060 ha-1) and B:C ratio 2.70. Among interaction, sensor based drip irrigation at 50% DASM along with foliar spray of nano urea, DAP and Zn at 30 and 60 DAS recorded significantly higher pod yield (2250 kg ha-1), haulm yield (2549 kg ha-1), nitrogen (105.8 kg ha-1), phosphorus (30.9 kg ha-1), potassium (60.6 kg ha-1) and zinc (0.69 mg kg-1).

    STUDIES ON FOLIAR NUTRITION OF GROWTH ENHANCER ON GROWTH AND YIELD OF MAIZE (Zea mays L.)
    (2023-01-05) SHREENIDHI, S N.; VENKATACHALAPATHI, V.
    The research entitled “Studies on foliar nutrition of growth enhancer on growth and yield of maize (Zea mays L.)” was conducted at Zonal Agricultural Research Station (ZARS), GKVK, University of Agricultural Sciences, Bangalore on red sandy loam soil. The experiment comprised of eleven treatments with three replications laid out in Randomized Complete Block Design. The treatments T1 to T6 includes three nutrient levels of RDF (50%, 75 % and 100 % RDF) applied to soil in combination with foliar spray of growth enhancer (GE) at 10 and 20 ml concentration and T7- urea spray - 0.5 % + 100% RDF, T8- nano N two sprays at 30 and 60 DAS + 50% RDN and 100% P & K, T9- nano N & P two sprays at 30 and 60 DAS + 50% RDNP and 100% K, T10- RDF with FYM and T11- only RDF. The results revealed that foliar nutrition of GE 20.0 ml per litre + 100 % RDF recorded significantly higher plant height (285.5 cm), leaf area (12697 cm2 plant-1 ), total dry matter (530.3 g plant-1), cob length (21.8 cm), number of rows cob-1 (16.0), number of kernels row-1 (40.3), number of kernels cob-1 (568.0), 100 kernels weight (35.9 g), kernel yield (7485 kg ha-1 ), stover yield (8556 kg ha-1), higher net returns (₹ 88,213 ha-1) and B:C ratio (2.50) compared to other treatments. However, it is found on par with GE 10.0ml per litre + 100 % RDF.

    STUDIES ON WEED DYNAMICS IN TRANSPLANTED FINGER MILLET UNDER LONG TERM MANURIAL EXPERIMENTS
    (University of Agricultural Sciences, Bangalore, 2023-10-21) NETRAVATI, KADAGAD; MUDALAGIRIYAPPA
    A field experiment was conducted to study the weed dynamics in transplanted finger millet under long term manurial experiments during kharif 2020 at AICRP on Long Term Fertilizer Experiments (LTFE), University of Agricultural Sciences, GKVK, Bangalore. The experiment was carried out in Randomized Complete Block Design with three replications and eleven treatments of different doses of fertilizer along with FYM and lime. Based on the research investigation, it was observed that among the grasses, Dactloctenium sp. and Digitaria marginata were the most predominant weeds in the experimental field, whereas Commelina benghalensis, Ageratum conyzoides and Borreria hispida were the most predominant weeds in the experimental plot among the broad leaved weeds. Cyperus rotundus was the only species found in the experimental plot among sedges and it was found in lower doses of fertilizer application i.e., 50 % NPK and control. Significant variation in weed density and biomass was recorded in different fertilizers treatment. Among different treatments, 100% NPK + FYM recorded significantly higher weed density of 147.34 m-2 and weed dry weight of 99.93 g m-2. Significantly lower weed density (20.63 34 m-2) and weed dry weight (25.80 g m-2) was recorded in control. Application of 150 % NPK recorded significantly higher growth attributes like plant height, number of leaves, leaf area, number of tillers and total dry wight which resulted in higher grain yield (2611 kg ha-1), straw yield (3729 kg ha-1), net returns (Rs. 50,455 ha-1) and B:C ratio (2.91).
