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 STANDARDIZATION OF ORGANIC CROP PRODUCTION TECHNOLOGIES FOR GROUNDNUT (Arachis hypogaea L.) – FINGER MILLET (Eleusine coracana(L.) Gaertn.) CROPPING SYSTEM IN THE EASTERN DRY ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-11-11) ANANDA, M.R.; SHARANAPPAField experiments were conducted during kharif and rabi seasons of 2015 and 2016 in farmer’s field of Chintamani taluk, Chikkaballapura district to develop organic production technologies for groundnut-finger millet sequence cropping system. The results revealed that application of EBDLM @ 25 kg N equi. ha-1 + three sprays of 3 per cent panchagavya recorded significantly higher pod and haulm yield of groun dnut (2231 and 3387 kg ha-1 respectively) as compared to other treatments which was evidenced by higher total dry mater accumulation and LAI (17.38 g plant-1 and 2.73 respectively) along with number of pods plant-1 (35.98) and kernel yield (1608 kg ha-1). Significantly higher grain yield and straw yield of finger millet (3787 and 5125 kg ha-1) was recorded with the application of EBDLM @ 50 kg N equi. ha-1 + three sprays of 3 per cent panchagavya as evidenced by more productive tillers plant-1, number of fingers earhead-1, earhead length and higher total drymatter accumulation plant-1(7.33, 9.33, 12.58 cm and 59.41 g, respectively). This could be attributed to more number of tillers plant-1 and LAI (7.87 and 2.98 respectively). Application of EBDLM @ 50 kg N equi. ha-1 + three sprays of 3 per cent panchagavya recorded higher oil and protein yield (799.64 and 430.55 kg ha-1 respectively) in groundnut and higher iron, calcium and protein (4.86 mg 100 g-1, 345.43 mg 100 g-1 and 10.95 %, respectively) content in finger millet grains. Significantly higher uptake of NPK (113.68, 12.80 and 100.97 kg ha-1, respectively in ground nut and 129.93, 12.70 and 82.10 kg ha-1, respectively in finger millet), availability (272.55, 38.52 and 170.65 kg ha-1, respectively in groundnut and 282.05, 50.22 and 182.40 kg ha-1, respectively in finger millet) and also net return and B:C ratio (Rs.79747 ha-1 and 3.14 respectively in groundnut and Rs. 113671 ha-1 and 3.85 respectively in finger millet) was recorded with EBDLM @ 25 kg N equi. ha-1 + three sprays of 3 % panchagavya in ground nut and 50 kg N equi. ha-1 + three sprays of 3 per cent panchagavya in finger millet crop. Pot culture experiment results indicated that, application of pongamia BDLM followed by glyricidia BDLM each @ 25 kg N equi. ha-1 recorded significantly higher pod and haulm yield (29.80 and 40.30 g plant-1) of groundnut as compared to other treatments.ThesisItem Open Access PERFORMANCE OF WEEDS COMPOST IN MAIZE-GROUNDNUT SYSTEM AND CROP GROWTH MODELING IN MAIZE(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-11-11) PRAMOD, G.; RAMACHANDRA PRASAD, T.V.A field experiment was conducted during 2009-10 and 2010-11 at Main Research Station, University of Agricultural Sciences, Hebbal, Bengaluru, to study the influence of weeds’ compost on productivity soil health and to know growth pattern through functional crop growth models. Fourteen treatments comprised were four weeds’ composts namely Chromolaena, Parthenium, Cassia, water hyacinth and FYM to supply 25 % Nitrogen along with 75% and 100% recommended fertilizer dose (RDF), 10 tons ha-1 FYM+ 100% RDF, 75% and 100% of RDF alone and absolute control. The RCBD design for maize –groundnut cropping system with three replications were followed. The higher kernel yields of maize were obtained with the application of 25 % N through four weeds’ composts and FYM + 100 % RDF application (6124 to 6248 kg ha-1) and were similar to the yield obtained in plot treated with 10 tons ha-1 of FYM + 100% RDF (6301 kg ha-1). Further, maize treated with 75% RDF along with 25% N through four weeds’ compost gave significantly higher kernel yield than 100% RDF alone (3766 kg/ha) and 25% N through FYM + 75% RDF (4018 kg/ha), 75% RDF alone (2568 kg/ha) and absolute control (1622 kg/ha). nevertheless, residual effect of these four weed composts and FYM at 25 % N substitution along with 75% and 100% RDF applied to previous maize on succeeding groundnut was conspicuous by providing higher kernel yield (1279 to 1410 kg ha-1), as compared to 75% RDF alone (702 kg ha-1) or 100% RDF alone (1159 kg ha-1) correspondingly. However, kernel yield was significantly lower in absolute control plot (574 kg ha-1) as compared to nutrients’ supplied plots in succeeding groundnut. Use of 25 % N from four weeds’ composts and FYM in maize-groundnut cropping systems along with 75% or 100% RDF produced the higher growth and yield attributes, organic carbon, available nutrients in soil, nutrients uptake by crops and substantial increase in soil biological health in terms of soil microbial biomass C and N, and phosphatase activity than the corresponding fertilizer alone and were similar to FYM usage. Further, the use of compost did not affect the time dependent growth phenomenon, but increased the dry matter production and lowered the phyllochrone requirement for leaf emergence in maize-groundnut cropping system as observed through functional crop growth models.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 PRECISION MANAGEMENT PRACTICES IN AEROBIC RICE UNDER DRIP IRRIGATION(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-09-11) PRABHUDEVA, D.

The experiment on precision nutrient management for targeted yield of rice was laid out in split plot design with three replications. Application of N & K in four equal splits up to 105 DAS recorded significantly higher grain yield (10.38 t ha-1) and net returns (` 1,06,394 ha-1) over application of N & K in three split doses. Moreover higher grain yield (12.08 t ha-1) and net returns (` 1,22,548 ha-1) was recorded at targeted yield level of 12 t ha-1. The experiment on precision management practices for growth and yield of aerobic rice was laid out in RCBD design with factorial concept including one control, one absolute control and replicated thrice. Among precision management practices, application of N & K in four equal splits up to 105 DAS with planting geometry of 25×15 cm with drip irrigation scheduling at 125% PE up to tillering + 150% PE from tillering to PI + 200% PE from PI to physiological maturity recorded higher grain yield (8.56 t ha-1), net returns (` 82,277 ha-1) and 119 per cent higher WUE (73.6 kg ha-cm-1) than control. Fertilizer recommendation based on STCR approach saved 50.75 per cent nitrogenous and 87.3 per cent potassic fertilizers compared to general recommendation of fertilizers for targeted yield of 6 t ha-1.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 EFFECT OF PLANTING GEOMETRY, METHODS OF ESTABLISHMENT AND NUTRIENT SOURCES ON GROWTH AND YIELD OF FINGER MILLET (Eleusine coracana L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-24) NARAYAN, HEBBAL; RAMACHANDRAPPA, B.

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.).
