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.

    STUDIES ON SEED SOURCE AND NURSERY MANAGEMENT REGIME IN INDIAN SANDALWOOD (Santalum album L.)
    (2025-12-30) SHWETHA, V. R.; M. MAHADEVAMURTHY
    A study was conducted to identify the potential seed sources from different regions of Karnataka and to develop nursery management regime for sandalwood. Seeds were collected from seven different locations of Karnataka (S1-Bevinahally; S2-Doranalu; S3-Gottipura; S4-Gungaraghatti; S5-Muddenahally; S6-Narasapura; S7-Tavarekere) and to compare S8-Marayoor seeds were procured from Kerala Forest Research Institute. Seed source S8 (68.66%) displayed the highest germination. Among the Karnataka seed sources S3-Gottipura (51.67%) recorded the highest germination and growth parameters. To improve the germination of Gottipura seed source, three distinct priming methods were employed, viz., biopriming with Pseudomonas fluorescens and Trichoderma viride, nutripriming with varying concentrations of KNO3 and MnSO4, and hydropriming with double distilled water. Nutriprimimg with MnSO4, at 0.4M concentration for 3 days, yielded optimal germination (84.00%), and hydroprimimg yielded lowest germination of all priming methods. Next step in nursery management regime is selecting suitable container and optimizing potting media for quality stocking production. Different types and sizes of container and potting media were evaluated. Out of 20 combinations studied 30 cm x 20 cm poly bag, in combination with a potting media soil, rice husk, and farmyard manure in 2:1:1 ratio, consistently recorded superior seedling growth. The assessed growth attributes, were significantly enhanced with this specific combination. Later growth attributes of the species was evaluated with six different host species (Crotalaria juncia, Mimosa pudica, Casuarina equisetifolia, Cajanus cajan, Crotalaria retusa and Alternanthera sessilis). Host species Crotalaria retusa recorded the highest growth attributes. Economic viability of the the treatments was also assessed. These series of experiments collectively offer a holistic framework for Indian sandalwood nursery management regime

    PLANT DIVERSITY IN AGRO-ECOSYSTEM ALONG RURAL URBAN INTERFACE OF BENGALURU AND THE CONSEQUENTIAL CHANGES IN THE ENVIRONMENT
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-12-20) DHANUSH, C.; DEVAKUMAR, A. S.
    Urbanization is a contemporary global trend resulting from population growth and migration, which concentrates the demand for food, energy and land at place of aggregation exerting pressure on the natural resources, leading to major changes in ecosystem and its services. Present study was aim to assessing the consequential changes in the plant diversity in agroecosystem along the rural urban transition (RUT) of Bengaluru. A total of 208 plant species were recorded in the agroecosystems along the RUT zones of Bengaluru out of 208 species 62 were cultivated crop species. Highest numbers of vegetable, fruit and flower crop species were found in the urban and transition zones, while in the rural zone number of staple food crop species cultivated were more. Similar trends were noticed in case of area cultivated across RUT zones. The chemical fertilizers and pesticides required for cultivation of vegetables, fruits and flower crops is found to be more compared to staple food crops. The source of water contamination is leaching and runoff of fertilizers and pesticides from agriculture fields, since higher quantities of these chemicals used in the cultivation in urban and transition zones is bound to add more contaminants to water bodies. From water quality it is found that in urban and transition zones water bodies are more contaminated compared to rural zone. Similar trend of soil quality deterioration was also noticed in RUT zones. Present study indicates the influence of urbanization on the biodiversity of agroecosystems of Bengaluru.

    ASSESSMENT OF DIVERSITY MEASURES OF BIOLOGICAL HETEROGENEITY USING INSECTS ATTRACTED TO LIGHT
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-07-24) JOSHUA MATATA, KIMONDIU; GANESHAIAH, K. N.
    A study was undertaken to assess (a) temporal patterns of insect activity and diversity, (b) evaluate the measures of biological diversity and, (c) identify possible indicator groups of total insect diversity in an agroecosystem at GKVK Campus, University of Agricultural Sciences, Bengaluru. The study used light traps to collect insects from 8th May, 2015 to 6th December, 2016 at 21 day intervals. A total of 209,098 individuals belonging to 764 morpho-species or Operational Taxonomic Units (OTUs), representing 101 families from 12 orders were collected. The Simpson’s index of diversity was 0.9732, the Shannon- Wiener index was 4.4443 and Avalanche index was 1.1693. Five orders, viz., Coleoptera, Hemiptera, Lepidoptera, Diptera and Hymenoptera dominated the collections. The relative proportions of these five orders at GKVK agroecosystem were different from those of the global and Indian insect communities; Coleoptera was over represented at GKVK while Lepidoptera, Diptera and Hymenoptera were under represented. Order Coleoptera was found to be a good indicator of the total insect diversity and this perhaps is because it was the most predominant component of the collections. The study recommends that light traps may be used for addressing broad ecological questions and to estimate the total insect diversity. While Simpson and Shannon-Weiner indices were strongly correlated with the species richness, Avalanche Index (AI) was not; probably because the biological heterogeneity that AI captures was not strongly reflected in species richness.Insect diversity and abundance was higher during summer and post monsoon and less during winter and rainy seasons. Rainfall and relative humidity over three days negatively affected the insect diversity and activity. Temperature cumulated over three week period negatively impacted the species richness though the abundance was not affected. Width of body increased with length at higher rate in Coleoptera and Hemiptera than Hymenoptera and Diptera suggesting that the former tend to become broader than the later. Coleoptera also had higher rate of increase in body weight with length probably due to the elytra. We have argued that insects adopt varying degrees of the two competing strategies for their protection: Thickening of forewing and adoption of flight agility. While Coleoptera and Hemiptera adopt the former, the Lepidoptera, Diptera and Hymenoptera adopt the later strategy.
