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.

    CONJUNCTIVE USE OF SEWAGE AND BOREWELL WATER ON PERFORMANCE OF WHEAT {Tritieum aestivnm L.) AT VARIED FERTILITY LEVELS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) SALAKINKOP, SHIDDAPPA R.; Hunshal, C. S.
    An investigation was conducted to study the conjunctive use of sewage and borewell water on performance of wheat at varied fertility levels on farmers fields near Agriculture Research Station, Dharwad during two consecutive rabi seasons of 1996-97 and 1997-1998. Field experiment was laid out in split-split plot design with sewage and borewell irrigated land as main plots, sources of irrigation (sewage irrigation, alternative irrigation and borewell irrigation) as sub plots and four fertilizer levels (0,50%, 75% and 100% RDF) in sub-sub plots in three replications. The sewage .irrigated land recorded significantly higher (about 23%) grain (43.7 q ha-i) and straw (54.6 q ha O yield than borewell irrigated land. It also recorded higher growth rate interms of CGR, RGR, NAR and dry matter and yield attributes. Sources of irrigation differed significantly producing higher grain yield in sewage irrigation (41.9 q ha-1) and alternate irrigation (39.5 q ha-1) compared to borewell irrigation (35.5 q ha-1). Straw yield also followed the same trend recording 57.7, 50.6 and 46.8 q ha-1 in sewage, alternate and borewell water irrigation, respectively.The grain yield was influenced mainly by yield components viz., ears m"2, ear weight, seeds ear' and test weight which were higher under sewage and alternate irrigations. Among the fertilizer levels, 100% RDF (45.1 q ha-1) and 75% RDl* (43.0 q ha-1) were on par with each other. This emphasised the importance of sewage irrigation in saving 25 per cent cost on fertilizer. Application of 75% RDF and 100% RDF to sewage irrigated land under sewage irrigalion resulted in higher hut similar grain and straw yield over other interactions. Same trend was noticed in both the lands wherever sewage and alternate irrigation.s were provided indicat ing saving of 25 per cent RDF with use of sewage water. (Juality of crops interms of protein, gluten improved due to sewage water application and there was no accumulation of heavy metals (Cr, Ni, Pb and Cd) in i)lant part.s above the threshold limit. Soil under sewage irrigated land contained significantly higher N,P,K, S and inicronutrients (Cu, Fe, Mn and Zn). Also soil maximum water holding capacity, BD and pH were improved. Content of toxic heavy metals in both lands did not increased significantly. Microbial population and their activity interms of dehydrogenase, phosphatase increased due to sewage application.

    INFLUENCE OF SOIL SOLARIZATION AND PLANT RESIDUE INCORPORATION ON WEED DYNAMICS AND PERFORMANCE OF CROPS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) CHITTAPUR, BASAVARAJ M.; HOSMANI, M.M.
    The increasing weed menace and decreasing soil health being the major deterrents in sustainable agricultural production, field experiments were conducted at Main Research Station, UAS, Dharwad during 1993-94 to 1995-96 to investigate the effects of i. kind and nature of polyethylene and placement heights on soil temperature, ii. kind and thickness of polyethylene and duration of solarization and iii. solarization and plant residue (viz., Glyricidia loppings, wheat straw or redgram stalks at 5t/ha) incorporation on weed growth and performance of crops, and iv. pre-incorporation residue (viz., wheat straw or cotton stalk at 5t/ha) inoculation (cattle dung or Phcmerochaete chrysosporium) on crop performance using randomised block design. Forage bajra, grain maize, soybean and wheat were the test crops. Polyethylene tarping of moist soil during summer months was effective in raising soil temperature. Thinner transparent polyethylene (TP 0.05 mm) was more effective than thicker (0.10 or 0.125 mm) transparent or black polyethylene particularly when placed close to the soil surface. Residue incorporation, at times reduced the magnitude of rise in temperature. These temperature changes influenced weed seed bank and dominant weeds such as Ageratum conyzoides, Trianthema portulacastntm and Commelina benghalensis were considerably controlled with TP 0.05 mm for 60 days. Solarization for shorter period was either not effective or stimulatory in some weeds. Among monocots, Denebra retrqflexa, Digitaria sangiiimlis, Panicum isachne and Cypenis rotundiis though decreased with intensive solarization (TP 0.05 mm for 50, or - for 60 days) found to be more resistant to high temperature effects. Plant residues though increased weed intensity in the first flush, resulted in substantial reduction in weed growth in subsequent flushes.Consequent to control of weeds and other growth influences summer soiarization with TP 0.05 mm for a period equal to or more than 50 days increased succeeding crop yields and such effects lasted over two consecutive seasons. Plant residues @ 5t/ha incorporated at the beginning of soiarization mineralized rapidly and improved yield of following crops. Green and pre - treated dry residues (natural biologically active dung slurry and decomposer Phanerochaete chrysosporium) improved the yields of immediate crops while untreated dry residues were particularly effective on the second crop grown in succession during the year.

    RESPONSE OF RABZ SORGHUM (Sorghum bicolor (L.) Moench) TO TILLAGE, MOISTURE CONSERVATION PRACTICES, ORGANICS AND NITROGEN IN VERTISOLS OF SEMI-ARID TROPICS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) PATIL, SHEKHARGOUDA L.; SHEETAVANTAR, M. N.
    Investigations to study the Response of rabi sorghum (Sorghum bicolor (L.) Moench) to tillage, moisture conservation practices, organics and nitrogen levels in vertisols of semi-arid tropics" were conducted during 1994-95 and 1995-96 at Regional Research Station, Bijapur. In the first experiment among the different tillage practices, deep tillage increased the soil moisture content, infiltration rate and decreased the bulk density compared to medium and shallow tillage. Deep tillage recorded higher grain yield (1877 kg ha-1) by 22 and 45 per cent over medium and shallow tillage respectively. Increase in depth of tillage increased the growth and yield component values and increased availability and uptake of major nutrients. Among different organic sources, subabul recorded higher grain yield (1636 kg ha by 8 per cent over vermicompost. Subabul application improved the soil physico-chemical propenies and nutrient uptake over rest of the organics. Application of 50 kg N ha-1 increased the grain yield (1708 kg ha-1) by 6 and 23 per cent over 25 and 'O' kg N ha-1 respectively. Increase in N dose upto 50 kg ha*' increased the availability and uptake of nitrogen, phosphorus and potassium. In the second experiment, formation of ridges and furrows and compartmental bunding increased the soil moisture content and recorded 1603 and 1567 kg ha-1 of grain yield which was higher by 26 and 23 per cent respectively over flat bed (1276 kg ha-1). Improved crop growth and higher nutrient uptake was observed with in situ moisture conservation practices over flat bed. Subabul application increased grain yield by 12 per cent (1570 kg ha-1) over vermicompost (1405 kg ha -1). Increase in nitrogen application upto 50 kg ha-1 improved the root growth, increased the nutrient availability and their uptake. Application of 25 and 50 kg N ha-1 increased the grain yield by 20 (1522 kg ha-1) and 31 per cent (1655 kg ha-1) respectively over control (1268 kg ha-1).
