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.

SATHISHA field experiment entitled “Effect of enriched urban compost and wastes on soil properties and productivity of maize (Zea mays L.)” was carried out in farmers field during 2022 near Bengaluru. Prior to initiation of the field experiment, urban compost and wastes i.e., FYM, urban solid waste compost, sewage sludge and humanure compost were enriched with five different microbial strains viz., Azotobacter chroococcum, Bacillus megatherium, Fraturia aurantia, Psedomonas fluorescens and Trichoderma viridae. Field experiment consisting of nine treatment combinations comprising varied levels of recommended NPK with enriched urban compost and wastes, was laid out in RCBD with three replications. The results revealed that application of 75 % NPK+ microbial enriched urban compost at 7.5 t ha-1 (T7) had significantly higher kernel yield (8512 kg ha-1), stover yield (12115 kg ha-1) and significantly higher uptake of N (112.07 and 136.09 kg ha-1) P (28.66 and 29.08 kg ha-1) and K (95.61 and 156.28 kg ha-1) were recorded in both kernel and stover, repectively. Treatment with 75 % NPK + microbial enriched urban compost at 7.5 t ha-1 (T7) recorded significantly higher soil available nutrients i.e., N (231.98 kg ha-1), P (60.68 kg ha-1) and K (238. kg ha-1) after harvest of the crop. Enriched urban solid waste compost, humanure compost, sewage sludge serves as alternative to FYM and they can also reduce the use of chemical fertilizers.ThesisItem Open Access ASSESSMENT OF SOIL QUALITY AND A MATHEMATICAL MODEL FOR PREDICTING NUTRIENT LEVEL IN FINGER MILLET UNDER LONG TERM INTEGRATED NUTRIENT MANAGEMENT(University of Agricultural Sciences, Bangalore, 2023-01-31) H. SURESH; Vasanthi, B. G.A field experiment was conducted in a 43 year old long term experimental field during kharif 2021, at AICRPDA, UAS, GKVK, Bangalore, under finger millet monocropping system using RCBD. Treatment comprised of Control, FYM 10 t ha-1, FYM 10 t ha-1 + 50 % RDF, FYM 10 t ha-1 + 100 % RDF, 100 % RDF, MR 5 t ha-1 , MR 5 t ha-1 + 50 % RDF, MR 5 t ha-1 + 100 % RDF. Soil quality indices were determined using principal component analysis linear scoring functions. The key indicators which contributed to soil quality index (SQI) were MBC from PC-1 and pH from PC-2. The largest SQI (0.967) was observed in T4 (FYM 10 t ha-1 + 100 % RDF) and smallest SQI (0.547) was in control. Application of 10 t ha-1 + 100 % RDF recorded higher grain and straw (24.5 and 32.9 q ha-1, respectively) yield and higher major, secondary and micronutrient status of soil. Similar results was observed with nutrient content and uptake. Mathematical model for predicting nutrient status using reliability indices Kg and Ks values showed high suitability for nitrogen and potassium but did not show the same for phosphorus. Soil nutrient efficiency of 0.058, 0.011 and 0.032 for N, P and K, respectively implied that soil could supply 5.8, 1.1 and 3.2 per cent of crop requirement of Nitrogen, Phosphorus and potassium, respectively. Overall, among the different nutrient management, combined application of organic source along with inorganic fertilizers enhanced soil nutrient efficiency.ThesisItem Embargo INFLUENCE OF SOIL AND FOLIAR APPLICATION OF SULPHUR AND BORON ON SOIL PROPERTIES, NUTRIENT UPTAKE AND YIELD OF SOYBEAN (Glycine max L.)(University of Agricultural Sciences, Bangalore, 2022-12-15) ERANAGOUDA, HALIKATTI; MAMATHA, BA field experiment entitled “Influence of soil and foliar application of sulphur and boron on soil properties, nutrient uptake and yield of soybean (Glycine max L.)” was carried out at Krishi Vignana Kendra, Hadonahalli in Rabi 2021. The experiment was laid out in a RCBD with eleven treatments which were replicated thrice. 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 EFFECT OF LONG TERM FERTILIZATION AND MANURING ON SOIL QUALITY AND NUTRITIONAL QUALITY OF MAIZE (Zea mays L.)(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 2023-01-05) BOMMIREDDY, MAMATHA; Kadalli, G. G.A study on “Effect of long term fertilization and manuring on soil quality and nutritionalquality of maize (Zea mays L.)” under finger millet-maize cropping system was carried out in LTFE plots which has been in progress since 1986 at UAS, GKVK, Bengaluru. Eleventreatments were laid in randomized block design with three replications. Soil samples (0-15 cmdepth) collected after the harvest of 35th crop cycle of finger millet (kharif 2021) were analyzed for 22 soil quality parameters and soil quality index (SQI) was assessed. The hybrid maize wasgrown in LTFE plots during Rabi 2021-2022 and qualities of grain and fodder were assessed.Higher SQI (0.95) was recorded in 100 per cent NPK+ FYM+ lime and lower (0.65) was in control treatment. Application of 100 per cent NPK+ FYM+ lime recorded significantly highergrain quality viz., geometric mean diameter (7.63 mm), bulk density (791 kg m-3), 1000 grain mass (444.10 g), colour (L*72.91, a*4.68, b*27.48), crude protein (10.35%), ash (1.73%),moisture (8.19%) and crude fibre (1.85%). The same treatment also recorded better fodder quality viz., moisture (9.04%), ash (9.29%), crude fat (2.89%), crude fibre (33.10%), non fibre carbohydrates (37.18%), dry matter digestability (60.20%), acid detergent fibre (36.84%) and neutral detergent fibre (58.23%). Inorganic fertilization alone, 100% N, 100% NP and control treatments recorded poor SQI and intern produced poor quality grain and fodder. The conjoint use of organic manures along with chemical fertilizers in balanced form is essential to maintain good soil quality and for quality maize production.ThesisItem Embargo Studies on soil and foliar application of zinc on soil properties, growth, Yield and quality of cabbage (Brassica oleracea var. capitata L.)(University of Agricultural Sciences, Bangalore, 2023-01-09) Lakshmi, V.; Subbarayappa, C.

Significantly higher zinc content (2.21 mg kg-1) was recorded in T5 (10 kg of Zn ha-1 through ZnSO4 as soil application along with RDF and FYM) in soil after harvest of cabbage.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.
