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.

ThesisItem Open Access STUDIES ON NIPPING AND ROW SPACING ON GROWTH AND YIELD OF PIGEONPEA (Cajanus cajan (L.) Millsp.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-09-12) MANJUNATHA, LAMBANI; Murali, KA field experiment entitled “Studies on nipping and row spacing on growth and yield of Pigeonpea (Cajanus cajan (L.) Millsp.)” was conducted during kharif, 2016 at ZARS, UAS, GKVK, Bengaluru under rainfed situation. The total amount of rainfall received during the crop season was 645 mm with 28 rainy days. The experiment was conducted on red sandy clay loam soil. The soil was medium in available nitrogen, phosphorus and potassium. The experiment consists of 12 treatments with three nipping levels (no-nipping, nipping at 50 and 70 DAS) and four spacing levels (90 cm x 30 cm, 120 cm x 30 cm, 150 cm x 30 and 180 cm x 30 cm ). Treatments were replicated thrice in a Randomized Complete Block Design (RCBD) with two factors. Significantly higher yield components like number of pods per plant and pod weight per plant (105 and 54.70 g plant-1 respectively) were recorded in nipping at 50 DAS. Similarly higher pigeonpea grain yield (1438 kg ha-1), gross return (Rs.57, 561 ha-1), net return (Rs.37, 156 ha-1) and benefit cost ratio (2.88) was recorded with nipping at 50 DAS and it was on par with nipping at 70 DAS . Significantly higher yield components like number of pods per plant and pod weight per plant (106 and 59.28 g plant-1 respectively) were recorded with 90 x 30 cm spacing. Further higher grain yield (1480 kg ha-1), gross return (Rs.59, 204), net return (Rs.39, 171) and benefit cost ratio (3.04) was recorded with spacing of 90 x 30 cm and it was on par with 120 x 30 cm spacing. The interaction between nipping and row spacing found insignificant.ThesisItem Open Access EFFECT OF FOLIAR NUTRITION ON GROWTH AND YIELD OF HYBRID MAIZE (Zea mays L.) IN SOUTHERN TRANSITION ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-28) SANGAMESH, KUMBAR; Bhairappanavar, S. T.A field experiment was conducted during Kharif – 2016 at College of Agriculture, Hassan, University of Agricultural Sciences, Bengaluru on sandy loam soil. The Hybrid Hema (NAH-1137) was sown at the spacing of 60 cm x 30 cm. The experiment comprised of nine treatments with three replications laid out in RCBD design. The treatments included two levels of RDF (75 % and 100 %) applied to soil in combination with foliar spray of water soluble macro nutrient (19:19:19) at 1 % and 2% concentration sprayed at 30, 45 DAS and 30, 45, 60 DAS. The treatments were compared with recommended UAS(B) package (100:50:25 kg NPK ha-1). The investigation revealed that significantly higher kernel yield and stover yield (101.50 and 163.20 q ha-1, respectively) was recorded with soil application of 100% RDF with 2% water soluble macro nutrient foliar spray at 30, 45 and 60 DAS. High yielding ability of the crop with this treatment was attributed to better yield components of cob weight (214.60 g), cob length (19.43 cm) and number of kernel rows cob-1 (18.37) as a result of higher growth components of plant height (243.67 cm), leaf area (10995 cm2) and total dry matter (474.10 g plant-1). The treatment also resulted higher net returns ( . 69,066 ha-1) and B:C ratio (2.8) compare to other treatments.ThesisItem Open Access RESPONSE OF PRE-RELEASE GROUNDNUT (Arachis hypogaea L.) GENOTYPES UNDER DIFFERENT SPACINGS AND FERTILIZER LEVELS IN EASTERN DRY ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-01-21) SOMANAGOUDA, BIRADAR; Shankaranarayana, V.Groundnut (Arachis hypogaea L.) is a major edible oil seed and a food crop of the world. It is an annual and highly self-pollinated crop belonging to family Leguminaceae and sub family Papilionaceae. It is popularly called as poor man’s almond and considered as king of oilseeds. Groundnut is native to Brazil and largely grown in the tropical and subtropical regions of the world. Cultivation of this crop is mostly confined to geographical belt between 40 °N and 45 °S latitude. Groundnut is a unique crop with attributes of oilseed, protein and carbohydrate, consisting of 44 to 50 per cent of edible oil, 25 per cent of high quality protein and 18 per cent of carbohydrates in addition to minerals and vitamins. Groundnut oil contains a higher proportion of unsaturated fatty acid, including essential fatty acids linolenic and linoleic acids (Desai et al., 1999). It is also fairly rich in calcium, iron, vitamin A and vitamin B complex (thiamine, riboflavin, niacin). It has multifarious usages such as in manufacture of soap, cosmetics, shaving cream, lubricants, etc., apart from using as major edible oil in the preparation of various food items. It plays an important role in agricultural economy and human life.ThesisItem Open Access STUDIES ON DRIP FERTIGATION ON GROWTH AND PRODUCTIVITY OF MAIZE (Zea mays L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-11) SHRUTHI, M. K.; Sheshadri, T.A field experiment was conducted at ZARS, V. C. Farm, Mandya during Kharif 2015 and 2016 to study the effect of drip fertigation on growth and productivity of maize (Zea mays L.). The experiment consist of two fertigation interval (4 and 8 days), two fertigation duration given as 25 % RDF (from sowing to 30 DAS) + 50 % RDF (31 to 50 DAS) + 25 % RDF (51 to 80 DAS) and 50 % RDF (from sowing to 30 DAS) + 25 % RDF (31 to 50 DAS) + 25 % RDF (51 to 80 DAS) with three fertilizer levels (75, 100 and 125 % RDF) replicated thrice in Randomised Complete Block design using factorial concept. The results revealed that the fertigation comprising of four days interval as 25 % RDF (from sowing to 30 DAS) + 50 % RDF (31 to 50 DAS) + 25 % RDF (51 to 80 DAS) with 125 per cent RDF recorded significantly higher plant height (194.7 cm), leaf area (7563 cm2 plant-1), total dry weight (329.13 g plant-1), cob length (20.2 cm), kernel weight cob-1 (150.9 g), kernel (86.85 q ha-1) and stover yield (103.73 q ha-1) when compared to control where surface irrigation and soil application of fertilizers was given (165.0 cm, 5959 cm2 plant-1, 270.99 g plant-1, 16.7 cm, 120.2 g, 68.81 q ha-1 and 79.20 q ha-1, respectively). Further, higher net returns (Rs. 84313 ha-1) and B: C (3.07) ratio were also realized with the same treatment when compared to control (Rs. 48422 ha-1 and 2.58, respectively). However, application of 75 per cent RDF recorded similar growth and yield parameters as that of control irrespective of fertigation interval and duration.ThesisItem Open Access STUDIES ON COMPARATIVE PERFORMANCE OF DIFFERENT METHODS OF RICE (Oryza sativa L.) CULTIVATION ON GROWTH, YIELD, NITROGEN DYNAMICS AND METHANE EMISSION(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-02) DILEEPKUMAR, H.

The per capita recommendation of pulses is 80 gday-1 as per FAO/WHO recommendation but availability is 31.6 g day-1. To make up this shortfall in supply at least 29.30 million tonnes of pulses will be required by 2020 (Ali and Kumar, 2005). Among the pulses, greengram is one of the most important pulse crops of South and South-East Asia. India alone accounts for 65 per cent of the world acreage and 54 per cent of the world production. In India it is the third most important pulse crop in terms of area (3.55 m ha), production (1.82 m t) and productivity (500 kg ha-1) next to chick pea and pigeon pea, (IIPR, 2010). In Karnataka it is widely grown in kharif season and covers an area of 2.84 lakh ha with a production of 0.69 lakh t and productivity of 243 kg ha-1 (Anon., 2014). More than 90 per cent of the area is concentrated in Northern districts of Karnataka viz., Belgaum, Bidar, Dharwad and Haveri.ThesisItem Open Access ORGANIC NUTRIENT MANAGEMENT IN FINGER MILLET (Eleusine coracana L.)(University Agricultural sciences,GKVk, Bangalore, 2017-07-29) NAVEENA, M.; SUJITH, G. M.A field experiment was carried out to study the impact of jeevamrutha and panchagavya on growth and yield of finger millet crop (variety-PR 202) at Research Institute on Organic Farming (RIOF), University of Agricultural Sciences, Bengaluru. Different levels and combinations of jeevamrutha (0, 500, 1000 l ha-1) and panchagavya (0, 2.5, 5, 7.5 per cent) were imposed to the crop comprising of 12 treatments. Jeevamrutha was given as soil drench and panchagavya as foliar spray at 20, 40, 60 days after transplanting. Two seedlings hill-1 were transplanted with spacing of 30 cm X 15 cm. Biometric observations (No. of tillers, plant height, leaf area, dry matter production) and yield attributes (number of fingers earhead-1, finger length, grain weight per plant, grain yield and straw yield) were recorded at different intervals. At harvest maximum and minimum tillers (13.63 and 10.26), plant height (96.9 cm and 76.6 cm), leaf area (906.6 cm2 and 377.7 cm2), dry matter (93.9 g and 51.6 g), number of fingers (7.26 and 5.53), finger length (6.38 and 4.06 cm), grain weight plant-1 (53.4 g and 24.46 g), grain yield (4574 kg ha-1 and 3256 kg ha-1) and straw yield (9359 kg ha-1 and 6515 kg ha-1) were recorded with crop treated with jeevamrutha at 1000 litres ha-1 + panchagavya at 7.5 per cent and control treatment (without jeevamrutha and panchagavya), respectively. Microbial and dehydrogenase activity were also studied.ThesisItem Open Access PRODUCTIVITY AND QUALITY OF BABY CORN AND SOIL HEALTH AS INFLUENCED BY ORGANIC NUTRIENT MANAGEMENT(University Agricultural sciences,GKVk, Bangalore, 2017-07-28) REKHA, M.
