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.

The results of the experiment indicated that significantly higher plant height (33.3 cm), number of branches (8.33), number of pods per plant (37.17), crude protein (37.83 %), oil content (21.52 %) and seed yield (26.85 q ha-1) were recorded in treatment which received RDF+ FYM+ ZnSO4 + foliar application of 1.0 % sulphur + 0.2 % boron (T11) whereas lowest plant height (26.5 cm), number of branches (6.17), number of pods per plant (15.67), crude protein (35.13 %), oil content (19.42 %) and seed yield (10.56 q ha-1) was recorded in T1(control). At harvest, after foliar spray the higher sulphur content in leaves (0.14 %) and the seeds (0.72 %) and higher boron content in leaves (11.92 mg kg-1) and the seeds (41.05 mg kg-1) of soybean was recorded in the treatment T11. Sulphur (22.61 kg ha-1) and boron (138.48 g ha-1) uptake was significantly higher in treatment. Significantly higher available sulphur (14.5 kg ha-1) and boron (0.46 mg kg-1) in soil at harvest of soybean was recorded in T3 treatment (RDF + Soil application of sulphur and boron).ThesisItem Embargo CHARACTERIZATION, CLASSIFICATION AND SUITABILITY EVALUATION OF MAJOR FINGER MILLET (Eleusine coracana L.) - GROWING SOILS OF KARNATAKA(University of Agricultural Sciences, Bangalore, 2022-12-29) NIVETHA, M; ANIL KUMAR, K SA study was undertaken to characterize, classify and evaluate suitability of major finger millet-growing soils of Karnataka. Fifteen typifying pedons were studied based on soil map of Karnataka from Eastern, Southern and Central dry zones and Southern transition zone. Major soils are deep or moderately deep, gravelly, well drained clayey or loamy. Desilication, leaching of bases, clay illuviation and sesquioxide accumulation are the major pedogenic processes observed. Finger milletgrowing soils are classified under Alfisols, Ultisols and Inceptisols based on argillic/kandic horizons, acidification and cambic horizons. In general soils are very strongly acid to neutral except Nagamangala and Hunsur, which are slightly and moderately alkaline respectively. Soil organic carbon stocks (kg m-3) were very high at Hosadurga and Hunsur with 22.98 and 20.09 respectively, moderate in Nelamangala, Magadi and Kunigal, (9.34, 9.37 and 10.73) medium in Kanakapura, Bangalore North, Kadur and Chiknayakanahalli (8.82, 7.07, 7.9, 7.69 and 6.27), low at Gubbi, Nagamangala and Channarayapatna (4.17, 4.22 and 3.02) and very low at Arasikere, Bangarapet and Siddlaghatta (2.38, 2.73 and 2.94). Kunigal, Kadur, Kanakapura, Hosadurga and Channarayapatna showed high suitability, Magadi, Nelamangala, Arasikere, Gubbi, Bangarapet, Nagamangala, Siddlaghatta, Bangalore North, Hunsur and Chiknayakanahalli showed moderate suitability for finger millet cultivation. Deficiencies of nitrogen (72.97 %), potassium (33.78 %), zinc (72.29 %) and boron (82.43%) in surface soils were observed and soil test based nutrients application is recommended to optimize yield and to improve soil health.ThesisItem Open Access CARBON AND NITROGEN DYNAMICS AS INFLUENCED BY DIFFERENT ORGANICS UNDER FINGER MILLET AND GROUNDNUT CROPPING SYSTEM(University of Agricultural Sciences GKVK, Bangalore, 2021-12-26) LAXMI NAGARAVALLI; LAXMI NAGARAVALLI; LAXMI NAGARAVALLI; LAXMI NAGARAVALLI; SARALAKUMARI, J.; SARALAKUMARI, J.; SARALAKUMARI, J.; SARALAKUMARI, J.The field experiment entitled carbon and nitrogen dynamics as influenced by different organics under finger millet and groundnut cropping system conducted at University of Agricultural Sciences, GKVK, Bengaluru during 2021-22 with eight treatments replicated thrice using randomized block design revealed that treatment with 75 kg FYM + 40 kg plot-1 urban compost significantly improved the carbon fractions viz., organic carbon (11.81 g kg-1 and 12.56 g kg-1), microbial biomass carbon (377.26 μg g-1 and 405 μg g-1), total carbon (15.2 g kg-1 and 15.40 g kg-1), labile carbon (35.41 % and 42.98 %), nonlabile carbon (60.07 % and 68.07 %) and nitrogen fractions viz., total nitrogen (857.10 mg kg-1 and 895.32 mg kg-1), ammonical nitrogen (99.1 mg kg-1 and 105.00 mg kg-1), nitrate nitrogen (49.50 mg kg-1 and 82.50 mg kg-1), microbial biomass nitrogen (42.50 μg g-1 and 46.50 μg g-1) in finger millet and groundnut, respectively. Growth and yield parameters of finger millet viz., plant height (129.47 cm), number of tillers hill-1 (8.39), grain yield (3892 kg ha-1) and straw yield (7247 kg ha-1) and in groundnut, plant height (34.4 cm), number of branches plant-1 (11.19), number of pods plant-1 (28.50), kernel yield (4352 kg ha-1) and haulm yield (11.19 kg ha-1) recorded were significantly higher in 75 kg FYM + 40 kg UC treated plot. Application of UC + FYM improves the soil physico-chemical, biological properties, growth and yield of the crops by improving carbon and nitrogen fractions which acts as bio-stimulant and promotes growth of crops.ThesisItem Open Access EFFECT OF NANO NITROGEN, COPPER AND ZINC LIQUID FERTILIZERS ON GROWTH, YIELD AND QUALITY OF POTATO (Solanum tuberosum L.)(University of Agricultural Sciences, Bangalore, 2021-12-27) MANIKANTA, B.; CHANNAKESHAVA, S.A field experiment was conducted in farmer’s field at Madenur village of Hassan district during Rabi 2020, to study the “Effect of nano nitrogen, copper and zinc liquid fertilizers on growth, yield and quality of potato (Solanum tuberosum L.)”. The experiment was laid out in randomized complete block design comprising ten treatments replicated thrice. The treatment consists of three nano fertilizers i.e. nitrogen, copper and zinc liquid fertilizers sprayed either alone or in combinations at 0.4% concentration with and without Recommended Dose of Fertilizers (RDF). The results revealed that significantly higher growth and yield parameters i.e. plant height (52.87 cm), number of branches plant-1 (10.55), number of leaves plant-1 (107.32), tuber yield (28.93 t ha-1) and total dry matter production of potato (5.01 t ha-1) was recorded in treatment which received RDF (50% Zn, 50% N & 100% PK) + 1st spray of Nano N at 25-30 DAP + 2nd spray of nano Zn after 10-15 days of 1st spray + 3rd spray of nano Cu after 10-15 days of 2nd spray (T10) and was on par with treatment RDF (50% N 100% PK ) + 2 sprays of Nano Nitrogen (T7) and RDF (50% Zn 100% NPK ) + 2 sprays of Nano Zinc (T8) compared to control (T1) plot (0% N and Zn, 100% P & K fertilizers). Similar effect was recorded for benefit cost ratio with higher gross returns (Rs. 2,02,520 ha-1), net returns (Rs. 1,46,371 ha-1) and B:C ratio (2.61) in T10 compared to other treatments.ThesisItem Embargo ASSESSMENT OF QUALITY OF MECHANIZED DRUM COMPOST AND ITS EFFECT ON SOIL PROPERTIES, GROWTH AND YIELD OF FRENCH BEAN (Phaseolus vulgaris)(University of Agricultural Sciences, Bangalore, 2022-12-19) DEEPA; PRAKASHA, H CCompost was prepared in the department of Soil Science and Agricultural Chemistry, University of Agricultural Sciences GKVK Bangalore. Three types of composting viz., Mechanized drum compost, vermicompost and FYM were prepared by using 1:3 ratio of wet and dry waste to assess the duration of compost period and quality of the compost. Among the three methods, the compost prepared from the mechanized drum compost was found superior in terms of physical, chemical and biochemical properties. The Mechanized drum composter took 35 days to composting, vermicompost 75 days and FYM 120 days. A pot culture study was conducted in green house to assess the quality of three methods of compost on soil properties, uptake, growth and yield of the French bean using eleven treatments in CRD design with three replications each. The yield and nutrient uptake of French bean was significantly highest with the application of 100 % NPK+ Mechanized drum compost. At harvest of French bean there was increase in major nutrients, secondary and micronutrients in soil with the application of 100 % NPK + Mechanized drum compost. Hence the use of Mechanized drum compost along with NPK fertilizers increases the concentration of nutrients in the soil and also increases the growthand yield of the crop.ThesisItem Open Access ASSESSMENT OF LAKE BIOMASS USING REMOTE SENSING AND GIS AND ITS EFFECT AS COMPOST ON SOIL PROPERTIES, GROWTH AND YIELD OF FRENCH BEAN (Phaseolus vulgaris) IN BENGALURU URBAN(University of Agricultural Sciences, Bangalore, 2022-12-08) Shalini; A. SathishA study was carried out in Department of Soil Science and Agricultural Chemistry, University of Agricultural Sciences, Bangalore to assess and quantify lake biomass (LB), to prepare lake biomass compost (LBC) and to assess the effect of enriched LBC on growth and yield of French bean. Extent of LB was assessed using supervised classification of Landsat-9 satellite image. The study revealed the highest biomass of water hyacinth and alligator weed was found in Bellandur (11897.70 t ha-1) and Varthur (7398.89 t ha-1) lakes among the nine lakes. Water hyacinth (2.65, 0.65 and 2.73 % NPK, respectively) and alligator weed (2.63, 0.43 and 2.57 % NPK, respectively) was used as raw material for compost. LBC after three months was enriched with microbial consortium, neem cake and single super phosphate for 15 days which was evaluated with different levels of enriched LBC using French bean as a test crop. Significantly highest yield (0.99 kg plant-1) of French bean was observed with application of Microbial consortium + Neem cake + SSP enriched (MNSE) LBC + 100 % NPK followed by MNSE-LBC + 75 % NPK. The available nitrogen, phosphorus and potassium was medium and heavy metal concentration in soil was decreased after harvest of French bean. The results indicated that the application of enriched LBC serves as best source of nutrients to urban farmers and helps to address the issue of effective utilization of lake biomass which otherwise is a major concern.ThesisItem Open Access SOIL AND FOLIAR APPLICATION OF ZINC FOR DIFFERENT APPROACHES OF NUTRIENTS ON SOIL PROPERTIES, NUTRIENT UPTAKE, GROWTH AND YIELD OF MAIZE (Zea mays L.)(University of Agricultural Sciences, Bangalore, 2020-11-20) SINCHANA, S; Subbarayappa, C.
