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 FEASIBILITY OF TRANSPLANTING PIGEONPEA IN SOLE CROPPING AND FINGER MILLET BASED INTERCROPPING SYSTEM
    (University of Agricultural Sciences GKVK, Bangalore, 2009-09-10) POORNIMA, D. S.; SHANKARALINGAPPA, B. C.
    A field experiment was carried out at the Gandhi Krishi Vignana Kendra, Bengaluru under rainfed conditions during kharif, 2008 to identify the optimum age of pigeonpea seedlings for transplanting, to study the effect of transplanting of pigeonpea on its growth and yield in sole cropping and finger millet based intercropping system, to know the effect of transplanted pigeonpea (intercrop) on finger millet (base crop) and to workout the economics of sole crop of transplanted pigeonpea and finger millet + transplanted pigeonpea (8:2) intercropping. The experiment was laid out in RCBD, replicated thrice with 11 treatments involving transplanting of pigeonpea of different aged seedlings (3, 4 and 5 weeks) under sole cropping as well as finger millet based intercropping system along with direct sowing. Transplanting of 5 weeks old seedlings o f pigeonpea had higher survival rate (92.4%) than 3 and 4 weeks old seedlings (75.6 to 85.7% and 83.3 to 90.0%). Transplanting of 5 weeks old pigeonpea seedlings as sole crop resulted in significantly 69.5 per cent higher grain yield (2669 kg ha'1) over direct sowing (1575 kg ha'1) and was on par with transplanting of 4 and 3 weeks old seedlings. Significantly higher grain yield of pigeonpea with transplanting o f 5 weeks old seedlings was due to higher growth and yield components. Transplanting of 5 weeks old pigeonpea seedlings in sole crop of pigeonpea gave significantly higher net returns o f Rs. 39983 ha'1 with B:C ratio of 1.99 than direct sowing (Rs. 21817 ha'1 with B:C ratio of 1.77). Finger millet + transplanted pigeonpea (8:2) intercropping with transplanting of 4 weeks old seedlings produced significantly higher pigeonpea grain yield (1347 kg ha*1 with finger millet grain yield o f 1880 kg ha'1) compared to finger millet + direct sown pigeonpea (391 kg ha'1 with finger millet grain yield of 1992 kg ha'1). The reduction in the grain yield of finger millet in finger millet + transplanted pigeonpea with 4 weeks old seedlings was 19.8 per cent, whereas it was 37.7 per cent with finger millet + transplanted pigeonpea with 5 weeks old seedlings. Finger millet + transplanted pigeonpea (8:2) with 4 weeks old seedlings gave higher LER (1.325), yield advantage (32.5%), net returns (Rs. 31874 ha'1) and B:C ratio of 1.90 than finger millet + direct sown pigeonpea (1.098, 9.8%, Rs. 16178 ha'1 and 1.28, respectively) and sole crop o f finger millet (net returns of Rs. 14910 ha'1 and B:C ratio o f 1.64).

    (University of Agricultural Sciences, Bangalore, 2009-08-15) ABDUL, WAHAB HEKMAT; Nagaraju
    A field experiment was conducted at Agroforestary field unit, University of Agricultural Sciences, Bengaluru during Kharif 2008, to study the integrated nutrient management in order to enhance the productivity of soybean under rainfed condition. The soil of the experimental site was red sandy clay loam. and slightly acidic (pH 5.7) and electrical conductivity of 0.06 dSm -1 at 250c. The organic carbon content was 0.32 per cent with medium available nitrogen (226.4 kg ha-1), available phosphorus (18.58 kg ha-1) and available potassium (176.32 kg ha-1). The experiment was laid out in split plot design with twelve total treatment combinations with three levels of farm yard manure (5, 10 and 15 t ha-1 ) and four levels of recommended dose of fertilizers (0, 50, 100 and 150 per cent NPK ). Application of different levels of farm yard manure (FYM) and recommended dose of fertilizer (RDF) significantly influenced the soybean seed and haulm yields. Significantly higher seed and haulm yields (1949 and 3163 kg ha-1, respectively) were recorded with 15 t FYM ha-1 followed by 10 t FYM ha-1 application (1902 and 2877 kg ha-1, respectively) as compared to 5 tones farm yard manure application per hectare (1813 and 2579 kg ha-1, respectively). Similarly higher seed and haulm yields were recorded significantly with application of 150 per cent recommended dose of fertilizer (2447 and 3753 kg ha-1, respectively). The interaction effect was found significant, among different treatment combinations, application of 15 t FYM ha-1 + 150 % RDF ha-1 recorded significantly higher seed yield (2490 and 4067 kg ha-1, respectively) as compared to other treatment combinations.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2009-07-10) SHARATH KUMAR, H C; MUDALAGIRIYAPPA
    Field experiment was conducted at Zonal Agricultural Research Station, Babbur Farm, Hiriyur during kharif 2008 to study the castor (cv. DCS-9) based intercropping systems with groundnut (cv. TMV-2), fingermillet (MR-1), chickpea (cv. KAK-2) and vegetable clusterbean (cv. Pusa-Nov-bahar) in 1:3 and 2:4 row proportions along with respective sole crops in a Randomized Complete Block Design with three replications. Sole castor produced significantly higher seed yield (1434 kg ha-1) as compared to intercropping systems except paired row system of castor with clusterbean (1417 kg ha-1) and paired row system of castor with groundnut (1400 kg ha-1) which were on par with each other. The growth components like plant height, number of branches plant-1, LAI and total drymatter at harvest and yield components such as number of spikes plant-1, number of capsules spike-1 and spike length were significantly higher in sole castor as compared to intercropping systems but, it was on par with paired row of castor intercropped with clusterbean or groundnut. Castor equivalent yield was significantly higher (2380 kg ha-1) with castor + clusterbean in 2:4 followed by the castor intercropped with clusterbean in 1:3 (2345 kg ha-1) and with groundnut in 2:4 (2136 kg ha-1) row proportions. The land equivalent ratio in castor with clusterbean in 2:4 row proportion was higher as compared to other intercropping and sole cropping treatments. The higher gross return (Rs. 54012, Rs. 49470 and Rs. 49046 ha-1), net return (Rs. 37938, Rs. 33076 and Rs. 32717 ha-1), and B:C ratio (3.36, 3.02 and 3.00) respectively, was recorded with castor intercropped with clusterbean in 2:4 or 1:3 followed by with groundnut in 2:4 row proportion. Thus castor intercropped with clusterbean in 2:4 or 1:3 and with groundnut in 2:4 row proportions appeared promising intercropping systems for the higher yield, economic returns and resource use efficiency.

    (University of Agricultural Sciences, Bangalore, 2009-09-15) DINESHA, M. S.; DHANAPAL, G. N.
    A field experiment was conducted to study the Chemical control of broomrape (Orobanche cernua Loefl.) in tomato (Lycopersicon esculentum Mill.) in farmer’s field at Hosakote village of Bagepalli taluk in Chickballapura district during Rabi-Summer 2006- 07. The experiment was laid out in Randomized Complete Block Design with ten treatments and replicated thrice. The broomrape spikes started emerging above-ground from 43-58 days after transplanting tomato. Flowering was completed by 7-13 days, stem drying was completed by 26-38 days and 37-50 days to complete its life cycle after emergence above-ground in tomato transplanted fields. Sulfosulfuron @75 g a.i. ha-1 recorded significantly lowest broomrape number (3.96 m-2), spike height (12.2 cm), spike dry weight (7.8 g m-2) with higher broomrape control efficiency (85.9 %), which also accounted for maximum plant height (77.3 cm), leaf number (61.4) and higher number of branches (8.35) at harvest. Dry matter accumulation in leaf, stem, fruit, and total dry matter accumulation of tomato was highest in weed free check (74.3, 37.4, 64.2, 176.1 g plant-1, respectively) and it was least in weedy check (46.6, 16.9, 31.8, 95.4 g plant-1, respectively). Among chemical control treatments, sulfosulfuron @ 75 g a.i. ha-1 recorded maximum dry matter accumulation in leaf, stem, fruit, and total dry matter accumulation of tomato (71.5, 34.6, 59.3, 165.6 g plant-1, respectively) at 90 DAT. Among all the chemical control treatments sulfosulfuron @ 75 g a.i. ha-1 recorded maximum number of fruits plant-1 (21.7), mean fruit weight (14.8 g), fruit weight plant-1 (2.6 kg plant-1) and it was least in weedy check 7.2, 7.7 g, 1.2 kg plant-1, respectively. Fruit yield of tomato was significantly higher in weed free check (68.17 t ha-1) and lower in weedy check (44.31 t ha-1). Sulfosulfuron @ 75 g a.i. ha-1 recorded higher fruit yield (66.82 t ha-1) and maximum net returns (Rs 1, 28,038 ha-1). Further, it is noteworthy to state that under heavy infested condition, application of sulfosulfuron @ 75 g a.i. ha-1 at 30 DAT is highly economical and effective in preventing development of broomrape seed bank in the soil

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2009-07-10) VIJAY, MAHANTESH; CHANDRAPPA, H
    A field experiment entitled “Growth, productivity and resource use in paddy under different establishment methods in Bhadra command” was conducted at Agriculture research station, Kathalagere, Davanagere, Univeristy of Agricultural Sciences, Bengaluru, during Kharif 2008 in clay loam soil. The experiment was laid out in Randomized Complete Block Design with 6 treatments as establishment methods viz., zero tillage, aerobic method, SRI method, drum seeding, Self propelled mechanical transplanting and hand transplanting replicated four times. Results revealed that SRI method recorded significantly higher plant height ( 81.7 cm), number of leaves (94.3 ), leaf area ( 2252.7 cm2), leaf area index (3.60 ), total dry matter (70.8 g ), which was superior over self propelled mechanical transplanting, hand transplanting and zero tillage however it was on par with aerobic method and drum deeding. Similarly SRI method recorded significantly higher grain yield and straw yield (5435 and 7842 kg ha-1, respectively), which was superior over zero tillage, hand transplanting, self propelled mechanical transplanting, drum seeding and where as it was on par with aerobic method. Zero tillage recorded significantly higher energy use efficiency (16.05) over other methods. The maximum water use efficiency was recorded in aerobic method (47.98 kg ha-cm-1) over other establishment methods. However, it was on par with zero tillage (46.25 kg ha-cm-1) and SRI method (43.45 kg ha-cm-1). With respect to economics, maximum B:C ratio was observed in SRI method (3.18 ) followed by drum seeding (3.17 ), aerobic method (3.07) self propelled mechanical transplanting(3.04), zero tillage (2.82) and hand transplanting (2.80) respectively.
