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.

A study to assess and evaluate carbon sequestration potential of soils of southern Karnataka with respect to climate, landform, soil type and different land use systems. Ten soil pedons were studied based on soil map of Southern Karnataka, 2 each at Brahmavara, Balehonnur, Hassan, Tiptur and Hiriyur representing the different agro-climatic zones and land use. Soils of the study area were moderately shallow in Hiriyur and the rest deep to very deep. Soil reaction varied from strongly acidic in Balehonnur and Brahmavara, slightly acidic in Hassan and Tiptur, moderately alkaline in Hiriyur. Higher potential organic carbon sequestration in kg per square meter of top 150 cm was recorded in Balehonnur at 11.97 (Hilly zone), followed by Brahmavara at 10.16 (Coastal zone), Hassan at 8.72 (Southern and Northern Transition Zone), Tiptur at 6.81 (Eastern and Southern dry zone) and Hiriyur at 1.81 (Central Dry Zone) and dynamic organic carbon at top 30 cm recorded 6.44, 5.37, 3.69, 2.11 and 1.24 respectively. The order of potential and dynamic carbon sequestration potential is per-humid, humid, subhumid, moist semi-arid and dry-semi-arid climate. Evergreen forests recorded highest carbon sequestration potential followed by coffee, semi-evergreen forests, arecanut, cashew, coconut, eucalyptus, scrub forest and field crops.ThesisItem Open Access EFFECT OF ZINC AND BORON ON SOIL PROPERTIES, GROWTH, YIELD AND QUALITY OF LITTLE MILLET (Panicum sumatrens L.) UNDER EASTERN DRY ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-09) KIRANKUMAR; CHIKKARAMAPPA, T.A field experiment was conducted at ARS, Baljigapade, Chikkaballapur district of Karnataka in soil which was deficient in DTPA extractable zinc and hot water soluble boron, to study the effect of zinc and boron on growth and yield of little millet. The experiment was laid out in Randomised Complete Block Design comprising of fourteen treatments replicated thrice. The results revealed that significantly higher grain and straw yield (12.60 and 21.14 q ha-1 respectively), nutrient content and uptake of N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu and B, crude protein (9.26 %) and crude fibre (6.57 %) by little millet was recorded in treatment which received 20 kg N ha-1, 20 kg P2O5 ha-1, 0 kg K2O ha-1, ZnSO4 @ 7.5 kg ha-1 and Borax @ 5 kg ha-1 combined with application of farm yard manure at 6.5 t ha-1 as compared to RDF (20:20:0 N: P2O5: K2O kg ha-1). The results of the present study evidently concluded that the application of 20: 20: 0 kg N: P2O5: K2O ha-1, ZnSO4 @ 7.5 kg ha-1 and Borax @ 5 kg ha-1 along with FYM at 6.5 t ha-1 under rainfed condition is beneficial for getting higher yield of little millet as well as higher benefit cost ratio (2.53) as compared to the RDF (20: 20: 0 kg N: P2O5: K2O ha-1) in zinc and boron deficient soils of Chikkaballapur district of Karnataka.ThesisItem Open Access STUDIES ON DIFFERENT SOURCES AND DOSES OF FERTILIZER NUTRIENTS ON TOMATO, SOIL PROPERTIES AND NUTRIENT UPTAKE IN EASTERN DRY ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-09) DAMINI, K.; BASAVARAJA, P. K.A field experiment entitled “Studies on different sources and doses of fertilizer nutrients on tomato, soil properties and nutrient uptake in eastern dry zone of Karnataka” was conducted in the STCR field during rabi/summer 2018. The experiment was laid out in a randomised complete block design with eight treatments and three replications. The results revealed that STCR approach for a targeted yield of 80 t ha-1 irrespective of different forms of complex fertilizer recorded higher growth, yield, nutrient uptake (plant and fruit) and nutrient use efficiency in tomato crop. Torrent coated complex (10:26:26) fertilizer treatments irrespective of different approaches of fertilizer nutrient application helped in achieving numerically higher growth, yield and yield parameters in tomato crop compared to respective normal complex (10:26:26) fertilizer treatments. The results clearly indicated that STCR treatment with torrent coated complex (10:26:26) fertilizer recorded higher fruit yield (89.81 t ha-1) and dry matter yield (43.91 q ha-1). Nitrogen, phosphorus and potassium uptake in shoot (100.58, 15.36 and 92.68 kg ha-1 respectively) and fruit (27.18, 4.30 and 29.26 kg ha-1 respectively) was also maximum in STCR treatment with torrent coated complex (10:26:26) fertilizer. The same treatment also recorded higher Apparent Recovery Efficiency (ARE) of nitrogen (0.20 kg kg-1), phosphorus (0.32 kg kg-1), potassium (0.47 kg kg-1), higher Agronomic Nutrient Use Efficiency (ANUE) of phosphorus (1705.03 kg kg-1), potassium (342.12 kg kg-1) and higher Response Yard Stick (RYS) (94.29 kg kg-1).ThesisItem Open Access EFFECT OF HUMIC ACID ON SOIL PROPERTIES, GROWTH AND YIELD OF FINGER MILLET IN SOILS OF LONG TERM FERTILIZER EXPERIMENT(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-09-27) MANOHAR, S. G.; Gowda, R. C.A greenhouse experiment was conducted during 2017 in Department of Soil Science and Agricultural Chemistry, GKVK, Bengaluru to study the effect of humic acid on soil properties, growth and yield of finger millet in soils of long term fertilizer experiment. Humic acid used in the study was characterized and found that C: N of the humic acid was 14.46:1 and total acidity was 5.46 meq g-1. The experiment was laid out in completely randomized factorial design with 22 treatment combination. The results revealed that significantly higher yield was obtained with the treatment receiving 100 % NPK + FYM + lime along with humic acid i.e. 21.35 g pot-1 grain and 31.25 g pot-1 straw yield, respectively. Significantly higher nutrient uptake was recorded in 100 % NPK + FYM + lime along with humic acid. Among the available nutrients in soil, significantly higher available phosphorus and micronutrients were recorded with application of application of humic acid. With respect to fertilizer nutrient treatments, treatment receiving 100 % NPK+ FYM+ lime recorded significantly higher available nutrient status in soil. However, it was statistically on par with 100 % NPK + FYM application. Results of the incubation studies indicated that, significantly higher available phosphorus was recorded in humic acid applied treatment at 60 and 90 days after incubation. The humic acid might have helped in solubilizing P from insoluble to soluble form resulting in its increase. However, difference in available nitrogen and potassium content of soil was not significant at different intervals of incubation.ThesisItem Open Access EFFECT OF PHOSPHORUS ENRICHED BIOCOMPOST ON SOIL PROPERTIES, GROWTH AND YIELD OF FINGER MILLET (Eleusine coracana G.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-05) LAVANYA, G.A field experiment entitled “Effect of phosphorus enriched biocompost on soil properties, growth and yield of Finger millet (Eleusine coracana G.)” was conducted during kharif 2018 at Shri Chamundeswari Sugars Ltd., Bharathi Nagar, Maddur (Tq), Mandya (D).

Significantly higher grain and straw uptake of major nutrients like N (44.28 kg ha-1 and 47.25 kg ha-1 respectively), P (15.38 kg ha-1 and 19.16 kg ha-1 respectively) and K (19.51 kg ha-1 and 52.36 kg ha-1 respectively) was recorded with the application of 100 % NPK + RP-PSB enriched biocompost @ 10 t ha-1. The economics of crop production also indicated the benefit of enrichment of biocompost and hence it may be followed to enhance crop productivity in farmer's field.ThesisItem Open Access ASSESSMENT OF SOIL QUALITY INDICATORS OF CHANNEGOWDARAPALYA MICROWATERSHED OF KUNIGAL TALUK, TUMKUR DISTRICT USING REMOTE SENSING AND GIS(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-02) HARSHA, M.; SATHISH, A.Soil quality assessment of Channegowdarapalya microwatershed, Kunigal taluk, Tumkur district was carried out using cadastral map and Cartosat-1 satellite imagery at 1:7920 scale. Soil site characteristics showed non-gravelly, slightly eroded, gently sloping land in majority of the area with near neutral soil pH and normal EC. The surface soil fertility maps indicated low OC, available nitrogen and available K2O, whereas available P2O5, secondary and micronutrients were adequate except zinc which was deficient. Eight out of fifteen soil profiles were selected as the master profiles. Soils were shallow to very deep, coarse textured, from strong brown to dark red coloured with subangular blocky structure. Nineteen soil phases including eight soil series were identified. There was increase in clay, bulk density, soil pH, available K2O, exchangeable calcium and magnesium with depth, whereas OC, available nitrogen, available P2O5 and available sulphur, micronutrients and dehydrogenase activity have decreased. The land suitability for selected cereals and horticultural crops indicated that, out of total area, 17.9 to 26.7 per cent of area was highly suitable for crops like mango, jamun, sapota, guava, cashew and 4.5 to 13.3 per cent area was not suitable for plantations. Marginally suitable to moderately suitable with major limitation of depth, texture and gravel in few parcels. Soil quality index recorded higher value in lower part of midland and lower in upland. Soil reaction (38%), calcium (34%), zinc (11%), OC (9%), and nitrogen (8%) contents are the major contributors for soil quality.ThesisItem Open Access POTASSIUM DYNAMICS IN SOILS UNDER CUSTARD APPLE BASED AGRI–HORTIULTURE SYSTEM(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-01) ANAND KUMAR, , L.; Krishna Murthy, R.Field experiment on “Potassium dynamics in soils under custard apple based agri– hortiulture system” was conducted in 9 years old established custard apple plantation at AICRPDA, GKVK, UAS, Bengaluru during kharif 2018. Soils of experimental site was sandy clay loam texture, slightly acidic in nature with medium fertility. Experiment consists of 15 treatments and replicated thrice under randomized complete block design. The potassium fracions of soils were higher in intercropping over sole cropping system. Before sowing and at harvest, higher water soluble K (6.66 and 6.14 mg kg–1), exchangeable K (72.77 and 65.55 mg kg–1) was recorded in custard apple + cowpea whereas, higher non–exchangeable K (309.60 and 300.54 mg kg–1) was recorded in custard apple + finger millet, respectively at surface soils. Lower water soluble K (3.12 and 2.98 mg kg–1), exchangeable K (47.27 and 41.13 mg kg–1) and non–echangeable K (209.20 and 200.54 mg kg–1) were recorded in foxtail millet, fodder maize and custard apple alone during before sowing and at harvest respectively. Water soluble, exchanageble and non–exchangeable K were decreased with increase in depth whereas, lattice and total K increases. The results Quantity/Intensity relationship of K showed that ARe K values ranged from 16 to 32×10–3 (mol litre−1)1/2 whereas, PBCK ranged from 10.4 to 14.1 (cmol kg–1)/(mol L–1)1/2. These values falling under low range (<20) of PBCK, it indicated that soils need judicious and frequent fertilization of K fertilizer for better crop production.ThesisItem Open Access STUDIES ON SOIL AND FOLIAR APPLICATION OF BORON ON SOIL PROPERTIES, GROWTH, YIELD AND QUALITY OF CAULIFLOWER (Brassica oleracea var. botrytis L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-01) KEERTHI, P.
