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 EFFECT OF FYM AND BIODIGESTER LIQUID MANURE ON GROWTH AND YIELD OF IRRIGATED SUNFLOWER (Helianthus annuus L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-12-02) PRADEEPA, PATEEL, G; Shankaralingappa, B. CA field experiment was conducted at the Agricultural Research Station, Kathalagere (Davanagere District, Karnataka) during rabi, 2010 to study the effect of FYM and biodigester liquid manure (BDLM) on growth and yield of irrigated sunflower and soil nutrient status after harvest of the crop. The experiment consisted of 14 treatments involving combination of different levels of FYM (5.0, 7.5 and 10.0 t ha-1) and BDLM equivalent to 40, 60, 80 and 100 kg N ha-1 along with recommended FYM + recommended dose of fertilizers (RDF) and RDF alone. The experiment was laid out in randomized completely block design with three replications. The application of FYM at 10 t + BDLM equivalent to 100 kg N ha-1 recorded significantly higher achene yield of sunflower (2333 kg ha-1), oil content (39.37 %), oil yield (918.57 kg ha-1), uptake of N, P, K by sunflower (118.52, 23.84 and 111.84 kg ha-1, respectively), net returns (` 42829 ha-1) and B:C ratio (3.40) than application of RDF alone (1108 kg ha-1 achene yield, 31.44 % oil content, 348.4 kg ha-1 oil yield, uptake of 56.77 kg N, 6.78 kg P and 45.49 kg K ha-1, ` 18701 ha-1 net returns with B:C ratio of 2.85), but was on par with application of FYM at 7.5 t + BDLM equivalent to 100 kg N ha-1 and FYM at 7.5 t ha-1 + RDF. Availability of N, P and K in the soil after harvest of sunflower was lower with the application of RDF alone. Significantly higher soil bacterial, fungal and actinomycetes population were observed with application of FYM at 10 t + BDLM equivalent to 100 kg N ha-1 than with application of RDF alone.ThesisItem Open Access USE OF JEEVAMRUTHA AND FARM YARD MANURE ON GROWTH AND YIELD OF FIELDBEAN (Lablab purpureus var. lignosus)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-08-04) SIDDAPPA; Murali, KA field experiment was conducted at organic farming block of UAS, GKVK, Bengaluru, during kharif 2014 to study the effect of jeevamrutha and farm yard manure (FYM) application on growth and yield of fieldbean. The experiment was laid out in a RCBD with three replications of two factors at different levels. The treatment combination include three FYM levels (100%, 150% and 200% N equivalents through FYM) and four jeevamrutha levels (0, 500, 1000 l ha-1 and 1500 l ha-1). Application of FYM at 200 % N equivalent recorded significantly higher grain yield (1136 kg ha-1) an increase of 16.7 % compared to FYM at 100 % N equivalent (946 kg ha-1). Similarly application of jeevamrutha at 1500 l ha-1 recorded significantly higher grain yield (1246 kg ha-1) an increase of 35.1 % compared to without jeevamrutha application (808 kg ha- 1). These treatments also showed similar trend with respect to growth and yield parameters and also nutrient concentration in plants (nitrogen, phosphorus and potassium). There was significant improvement in soil nutrient status (available N, P2O5 and K2O) and soil microbial load (bacteria, fungi, actinomycetes, phosphate solubilizer and N-fixer) as FYM and jeevamrutha levels increases after harvest of the crop. Higher B:C ratio (1.99) was realized with FYM at 200 % N equivalent + jeevamrutha at 1500 L ha-1 followed by 150 % N equivalent through FYM + jeevamrutha at 1500 l ha-1 (1.91).ThesisItem Open Access GROWTH, PRODUCTIVITY AND DISEASE INCIDENCE OF POTATO (Solanum tuberosum L.)

The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and twelve treatment combinations . The investigation revealed that, 125 % recommended N and K + 0.5 % ZnSO4 * + 0.2 % Borax* @ 45 DAP recorded significantly higher plant height (68 cm), number of shoots (4.2 plant-1), number of leaves (88 plant-1), total dry matter production (65 g plant-1) and late blight incidence and severity recorded (9 %) 75 DAP and tuber weight (279.5 g plant-1), number of tubers (4.9 plant-1), tuber yield (23.3 t ha-1), protein content (13.9 %) and nutrient uptake (104.7, 36.4 and 103.7 kg N, P2O5 and K2O ha-1) at harvest. However, it was on par with 75 % recommended N and K + 0.5 % ZnSO4 * + 0.2 % Borax* @ 45 DAP. Higher net returns ( .156049 ha-1) and B:C ratio (3.4) was recorded in 75 % recommended N and K + 0.5 % ZnSO4 * + 0.2 % Borax* @ 45 DAP.ThesisItem Open Access INFLUENCE OF ORGANIC SOURCES OF NUTRIENTS ON GROWTH, PRODUCTIVITY AND QUALITY OF BABY CORN(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) KEERTHIRANI, D. S.; SharanappaA field experiment was conducted at University of Agricultural Sciences, GKVK, Bengaluru during kharif, 2014 to study the effect of organic sources of nutrients on growth, yield and quality of baby corn. The experiment was laid out in a RCBD with nine treatments replicated thrice. Application of poultry manure and enriched biodigested liquid manure (EBDLM) each at 75 kg N eq. ha-1 + panchagavya (3 %) at 15 and 45 days after sowing (DAS) + vermiwash at 30 DAS recorded significantly higher baby corn and green fodder yield (13.75 and 42.43 t ha-1, respectively), which was on par with application of FYM at 10 t ha-1 + 150:75:40 kg NPK ha-1 (14.76 and 43.88 t ha-1, respectively). This was mainly attributed to higher growth and yield parameters. The quality parameters viz., protein content, total soluble solids, fibre content and moisture content and the sensory attributes viz., appearance, aroma, taste, colour and over all acceptability of baby corn were also superior with the application of poultry manure or vermicompost and EBDLM each at 75 kg N eq. ha-1 + panchagavya (3 %) at 15 and 45 DAS + vermiwash at 30 DAS as compared to control. Similar trend was also observed with the available NPK status in soil. The highest B:C ratio (4.54) was obtained with FYM 10 t ha-1 + 150:75:40 kg NPK ha-1 followed by poultry manure and EBDLM each at 75 kg N eq. ha-1 + panchagavya (3 %) at 15 and 45 DAS + vermiwash at 30 DAS (4.34).ThesisItem Open Access INTEGRATED NUTRIENT MANAGEMENT IN MULBERRY (Morus alba L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) MALLAPPA; Shankaranarayana, VA field experiment was conducted in farmer’s field near College of Sericulture, Chintamani, during late Kharif - 2014 to study the effect of integrated nutrient management practice on growth and yield of mulberry.

These treatments also showed similar trend in growth and quality parameters. Whereas, significantly lower leaf yield was recorded in FYM at 20 t ha-1 + recommended dose of NPK (9.03 t ha-1). Whereas, higher net returns ( 30158 . ha-1) and B:C ratio (1.80) was recorded with FYM at 20 t ha-1 + 50% inorganic N + pongamia cake (25% N equivalent) +75% P & 100% K inorganic + Azospirillum + PSB + Pseudomonas florescence.ThesisItem Open Access EFFECT OF NUTRIENT MANAGEMENT WITH DIFFERENT SOURCES AND LEVELS OF WATER SOLUBLE AND NORMAL FERTILIZERS ON GROWTH AND YIELD OF GROUNDNUT (Arachis hypogaea L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) SRIJITA, PAUL; MUDALAGIRIYAPPAA field experiment was carried out during kharif 2014 at Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bengaluru to study the effect of different sources, levels of fertilizer and methods of fertilizer application on growth and yield of groundnut in red sandy loam soil. The experiment consisted of ten treatments viz., 50, 62.5, 75 and 100 % of RDF through normal fertilizers, water soluble fertilizers (WSF) and combination of both with soil application, fertigation as well as foliar application methods which were replicated thrice in RCBD. The investigation revealed that drip fertigation of water soluble fertilizers at 50 % RDF along with foliar spray of water soluble fertilizers at 12.5 % RDF recorded significantly higher pod yield (2910 kg ha-1), growth parameters (plant height, leaf area, total dry matter production) and yield attributes (pods plant -1, pod weight plant - 1, 100 kernel weight, kernel and haulm yield). Uptake of major nutrients (N, P and K) in groundnut was also significantly higher in this treatment. However it was on par with drip fertigation of normal fertilizers at 50 % RDF + water soluble fertilizers at 50 % RDF. It was also observed that due to drip irrigation, the amount of water saved was 33.7 % over surface irrigation. Drip fertigation of water soluble fertilizers at 50 % RDF along with foliar spray of water soluble fertilizers at 12.5 % RDF saved 37.5 % fertilizers with higher net returns ha-1 (` 65,134 ha-1) and B: C of 2.20 compared to soil application of normal fertilizers at 100 % RDFThesisItem Open Access STUDIES ON MICRO SPRINKLER FERTIGATION IN GROUNDNUT (Arachis hypogaea L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) SAMEERKUMAR, D; JAYADEVA, H.MA field experiment was conducted during Kharif 2014 at ZARS, University of Agricultural Sciences, Bengaluru to study the effect of micro sprinkler fertigation on growth, yield, water use efficiency (WUE), nutrient use efficiency (NUE) and economics of groundnut in red sandy loam soil. The experiment was laid out in RCBD with nine treatments and replicated thrice. Micro sprinkler fertigation of WSF at 100 % RDF increased the pod yield significantly (2882 kg ha-1) over all other treatments. However, it was on par with micro sprinkler fertigation of WSF at 75 % RDF. Among the micro sprinkler fertigation treatments significant yield reduction was noticed with micro sprinkler fertigation of normal fertilizers (NF) at 50 % recommended dose. Micro sprinkler fertigation of WSF at 100 % RDF recorded significantly higher number of pods plant-1 (34.2) and WUE (64.9 kg ha-cm-1) compared to surface irrigation. Micro sprinkler fertigation of WSF at 75 % RDF recorded significantly higher agronomic nutrient use efficiency (70.3, 22.3 and 44.6 kg kg-1 of N, P and K, respectively). Micro sprinkler irrigation saved 29.8 % water over surface irrigation. Micro sprinkler fertigation of NF at 100 % RDF recorded higher B:C ratio (2.82) followed by micro sprinkler fertigation of NF at 75 % RDF (2.64). July,ThesisItem Open Access INTEGRATION OF PRE AND POST-EMERGENCE HERBICIDES AND CULTURAL PRACTICES FOR WEED MANAGEMENT IN SUNFLOWER (Helianthus annuus L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) ROHINI, N. METI; Geetha, K. NA field experiment was conducted during Kharif 2014 at AICRP on sunflower, ZARS, UAS, Bengaluru. The experiment consisted of nine treatments laid out in randomized block design. In this experiment one pre-emergence, four post-emergence herbicides and farmers practice i. e., two IC at 20 and 40 DAS + one HW at 30 DAS, which was compared with three hand weedings at 15, 30 and 45 DAS and unweeded check. Among the different weed management practices, application of pendimethalin at 1.0 kg a. i. ha-1 as PE + quizalofop-ethyl 10 EC at 37.5 g a. i. ha-1 at 17 DAS as directed POE on weeds recorded significantly higher seed and oil yield (1797 and 675 kg ha-1, respectively) which was found to be on par with weed free (1824 and 697.4 kg ha-1, respectively) and farmers practice (1888 and 726.4 kg ha-1, respectively). These treatments registered lower weed density and dry weight at harvest (11.13, 7.56 and 9.57 no. m-2 and 10.00, 7.39 and 5.51 g m-2, respectively). The yield components: seed yield capitulum-1 (30.33, 30.93 and 34.33 g), capitulum diameter (17.40, 18.00 and 18.60 cm) and hundred seeds weight (4.42, 4.56 and 4.78 g) were significantly higher with the same treatments. Though highest net returns (` 35,092 ha-1) was recorded in farmers practice, highest MR:MC (10.75) and B:C ratio (2.73) were recorded in pendimethalin at 1.0 kg a. i. ha-1 as PE + quizalofop-ethyl 10 EC at 37.5 g a. i. ha-1 at 17 DAS as directed POE on weeds.ThesisItem Open Access BORON NUTRITION IN SUNFLOWER(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) PRATHIMA, A. S; Shivaramu, H .SA field experiment was conducted to study the response of sunflower hybrid, KBSH-53to boron on a soil with low boron (0.3 ppm) during kharif-2014 at All India Coordinated Research Project on Sunflower, Gandhi Krishi Vignana Kendra, Bengaluru. The experiment laid out in a Randomised Complete Block Design with 11 treatments replicated thrice. Treatments consisting of application of recommended dose of fertilizer (RDF-90:90:60 kg NPK ha-1 and 7.5 t FYM) alone, RDF along with application of borax through seed treatment, soil application, spraying and dusting to capitulum at ray floret opening stage. The results revealed that application of RDF + borax @ 0.4 % spray to capitulum at ray floret opening stage recorded significantly higher seed and oil yield (2176 kg ha-1 and 858.5 kg ha-1, respectively). It was attributed to higher SPAD (chlorophyll content)reading of 44.38 at 50 % flowering, higher leaf area (4269 cm2 plant- 1)at 60 DAS and higher yield attributing characters like capitulum diameter (15.97 cm), test weight (5.22 g 100 seeds-1), total seeds (1233 numberscapitulum-1), filled seeds (1195 number capitulum-1), seed yield (48.87 g plant-1), lower chaffiness (3.07 %) and higher N (112.09), P (25.62 kg ha-1) and K (93.86 kg ha-1) uptake. Higher net returns (` 44527 ha-1) and benefit cost ratio (3.37) was obtained in this treatment.
