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.

    INTEGRATED NUTRIENT AND WATER MANAGEMENT IN FIG (Ficus carica L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-01-05) SRINIVAS, N; jaganath, s
    The experiment entitled 'Integrated nutrient and water management in fig (Ficus carica L.) cv. Poona' was conducted at Precision Farming Development Centre, Department of Horticulture, GKVK, Bengaluru during 2005 and 2006 to know the influence of irrigation levels and integrated nutrient management (INM) on growth, yield and quality parameters. The data revealed that, 100 per cent Epan replenishment of water significantly influenced the growth parameters viz., plant height, plant spread, canopy volume, shoot length, trunk girth, number of secondary branches, leaf area, chlorophyll content and N, P and K in leaves. Further, the fruit length ( 4.87cm), fruit breadth (4.66 cm), fruit weight (31.94 g), number of fruit per plant (116.33) and fruit yield (3.61 kg/plant) was significantly higher with 100 per cent Epan replenishment of water. While, the quality parameters viz., TSS (15.67° Brix) and total sugars (17.14 %) were significantly higher with 75 per cent Epan replenishment of water. Application of 100 per cent RDF + 150 g each of Azospirillum sp., T. harzianum and PSB per plant significantly influenced the fruit length ( 4.92 cm), fruit breadth ( 4.66 cm), number of fruit per plant (134.87) and fruit yield ( 4.30 kg/plant), compared to 50 per cent RDF + 150 g each sp., and PSB. Interaction effect of irrigation and INM Azospirillum revealed T. that, harzianum 100 per cent Epan replenishment of water coupled with 100 per cent RDF + 150 g each of irillum sp. + T. harzianum + PSB recorded similar trend for growth and yield parameters.Azosp Microbial inoculants for rooting of fig cuttings under green house, revealed better shoot and root growth in 'Dinakar' compared to 'Poona'. Further, the microbial consortium of Azospirillum sp., PSB, T. harzianum and G. fasciculatum inoculation recorded early sprouting and maximum shoot length, number of leaves per cutting, number of primary roots per cutting, root length, rooting percentage and survival percentage compared to individual inoculation.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-11-26) SRINIVASA REDDY, S.Y.; Krishna Manohar, R.
    A field experiment was conducted during Kharif and rabi seasons of 2007-08 and 2008-09 to study the weed management in tomato-radish cropping system under irrigation with fifteen treatments replicated thrice in RCBD. Pre-emergence herbicides namely alachlor at 0.75, 1.0 and 1.25 kg a.i. ha-1, pendimethalin at 0.75, 0.97 and 1.20 kg a.i. ha-1, oxyfluorfen at 0.094, 0.10 and 0.106 kg a.i ha-1, metribuzin at 0.25, 0.35 and 0.45 kg a.i. ha-1 were used. Hand weeding was taken up at 20 and 40 DAT, paddy straw was used as mulch and an unweeded control. Same treatments were imposed for radish crop except hand weeding which was taken up at 10 and 20 DAS. Among the herbicides, metribuzin at 0.45 kg a.i. ha-1 and pendimethalin at 1.20 kg a.i. ha-1 reduced the weed density and dry weight significantly in tomato and radish, respectively. Metribuzin at 0.45 kg a.i. ha-1 recorded highest plant height, number of leaves, number of branches, number of fruits, fresh and dry weight of fruits, fruit yield (71.5 t ha-1) and B: C ratio (4.23). In radish, pendimethalin at 1.20 kg a.i. ha-1 recorded highest plant height, number of leaves, leaf dry weight, root yield (25.23 t ha-1), B: C ratio (3.50), fresh weight of leaf and root. The maximum net returns was obtained with the application of metribuzin in tomato and pendimethalin in radish. Hand weeding at 20 and 40 DAT in tomato and 10 and 20 DAS in radish recorded higher net returns in respect of mechanical operations. Germination per cent in french bean taken up after the application of herbicides to tomato and radish crops indicated that there was no inhibition of germination of French bean in any of the herbicide applied plot. The results indicated that metribuzin and pendimathalin used in tomato and radish respectively, helped in obtaining effective weed control and economical yield with no residual effect on succeeding French bean crop.

    (University of Agricultural Sciences GKVK, Bangalore, 2015-03-12) SEETHARAMU, G. K.; KUMAR, D. P.
    An experiment was conducted to evaluate the growth, yield, flower quality of gerbera under polyhouse condition during 2007 to 2009 at Department of Horticulture, GKVK, Bangalore. The main objective of the study was to identify suitable spray interval and ideal micronutrient and dosage to obtain better growth, superior quality flowers and maximum yield. Of the two spray interval, significantly higher plant height, more number of leaves per plant, maximum plant spread and higher sucker production was recorded with application of micronutrients at 15 days interval than weekly interval. Among varied levels of micronutrients, treatment T11 (MnSO4 @ 0.25% + ZnSO4 @ 0.25% + Borax @ 0.10% + FeSO4 @ 0.25% + CuSO4 @ 0.05%) recorded taller plant, maximum plant spread and higher sucker production during entire crop period. Foliar application of FeSO4 @ 0.25% induced early bud emergence (48.43 days). Among quality characters, significantly highest stalk length (55.07 cm), stalk diameter and higher flower head diameter was obtained in MnSO4 @ 0.25% + ZnSO4 @ 0.25% + Borax @ 0.10% + FeSO4 @ 0.25% + CuSO4 @ 0.05% at fortnightly spray interval (S2T11). Significantly highest cumulative cut flower yield per plant per square meter and per ha was recorded at 15 days spray interval (81.01 nos., 599.94 nos. and 47.95 lakh respectively) over seven days. Treatment T11 produced highest cumulative yield per plant per meter square and per ha (94.11nos., 696.42 nos. and 55.70, lakh respectively). Significantly highest percentage of first grade flowers (78%) was recorded in treatment T11 at fortnightly spray interval. Higher accumulation of micronutrient content in leaf was found in weekly spray interval. Vase life of cut flowers obtained in treatment T11 and T5 was maximum (14 days) and S2T11 treatment combination registered maximum net returns (Rs. 34,55,588 ) and highest cost benefit ratio of 1.39.

    THEME GARDENS: AN ASSESSMENT OF THEIR CONCEPTUALIZATION IN BENGALURU
    (University of Agricultural Sciences GKVK, Bangalore, 2015-01-10) CHARAN, A.; SATHYANARAYANA, B. N.
    Natural settings make us feel one with nature and at peace with the universe which in turn could lead to transcendental experience. A garden has always been an interesting and masterly synthesis of geometric or fantastic realities and plant elements skillfully combined one with the other, thus representing a privileged place for experimentation of the artistic sense and planning wits in all civilizations. Themed Gardens are not a new concept. In the ancient India, though not known for any style of its own the gardens created were of theme or subject based for example, Udyana, Promododyana, Nandanavana and Vrikshavatica where each served a purpose. The aim of theme gardens and their interpretation is to bridge the gap between people and plants. Bengaluru, despite being one of the fastest growing cities in India, has still managed to hold on to its status as the ‘Garden City of India’. Yet, in recent times, many green spaces are being encroached on for developmental activities, amongst vociferous protests by local citizens, while at the same time a number of smaller neighborhood parks have been created in many locations. Therefore, the focus of the study was to analyze Bengalureans’ notions, ideas and beliefs qualitatively. Ex-post facto research design was used. Participants were randomly chosen to answer a questionnaire, among the park visitors irrespective of their age, social status and occupational back ground. Survey was conducted among visitors of urban theme gardens/park in the metropolitan city of Bengaluru, Karnataka. Hence, this study provides baseline surveys of species composition of plants and trees in the public parks of Bengaluru city and an understanding about the public’s perceptions with respect to theme gardens, particularly their perception specifics so that ‘theme gardens’ can be conceptualized to best suit the needs and interests of Bengalureans.

    (University of Agricultural Sciences GKVK, Bangalore, 2015-02-10) BHOOMIKA, H. R.; VASUNDHARA, M.
    A study on noni (Morinda citrifolia L.) was undertaken at Gandhi Krishi Vigyana Kendra, University of Agricultural Sciences, Bengaluru, during 2013-14. The study comprised of seven treatment combinations viz., T1- Control (no fertilizer application), T2- 50:100:100 kg ha-1 NPK, T3- 50: 225:50 kg ha-1 NPK, T4- 50:100:100 kg ha-1 NPK - 50% of recommended P through bone meal, T5- 50: 225:50 kg ha-1 NPK - 50% of recommended P through bone meal, T6- 50:100:100 kg ha-1 NPK - 100% of recommended P through bone meal and T7- 50: 225:50 kg ha-1 NPK - 100% of recommended P through bone meal. The treatments T5 and T7 have recorded significantly higher growth parameters like plant height (3.61m and 3.67m respectively) and canopy spread (7.50m2 and 6.54 m2 respectively) compared to control. Application of higher dose of P has resulted in early flowering and fruit maturity. Peak flowering was during July and August. Treatment T5 recorded significantly maximum fruit weight (29.97 g/fruit), fruit volume (26.23 cm3) and fruit to seed ratio (8.25). Significantly higher yields than control were also recorded in T5 (35.83 kg tree-1 and 39.81 t ha-1) followed by T7 (34.43 kg tree-1, 38.26 t ha-1). Highest available soil N and P were recorded in T3 (238.3kg/ha: 37.51kg/ha) and K in T2 and T6 (192.4kg/ha each). The treatment T3 recorded maximum B:C ratio (3.85). Qualitative screening of fruit juice showed the presence of alkaloids, saponins, proteins, ascorbic acid, gums and mucilages, phenolic compounds, tannins and oils in the fruit juice. The treatment T5 and T7 have proven best in terms of quality by recording significantly higher moisture, juice, TSS, alkaloid, flavonoid, saponin and protein contents. The treatments T5 and T7 have proven best in terms of yield and quality and can be rated as superior treatment combinations for noni cultivation.

    RAPD AND AFLP MARKERS BASED DNA FINGERPRINTING AND DIVERSITY STUDIES IN TAMARIND (Tamarindus indica L.)
    (University of Agricultural Sciences GKVK, Bangalore, 2010-09-22) ALI QAID AHMED, YAHYA.; Narayanaswamy, P.
    A study was conducted at Plant Molecular Biology Laboratory, Division of Horticulture, Kirk house Trust (KHT) Department of Biotechnology and Department of Plant Breeding, U.A.S., G.K.V.K Bangalore. During 2008 – 2010. Significant genotypic differences were observed for the traits under study thereby indicating presence of large genetic variability in the material. Among 36 tamarind genotypes 26 were orthotropic and 10 were plageotropic. Three types of pod shapes observed viz. straight, curved and semi curved. Three colored pulp were observed brown, light brown and dark brown. The leaf colour ranged from dark green to light green. All the PCV values were higher than GCV values for each character. The higher Heritability was observed in pulp weight (90.3%), pod weight (87.2%) seed weight (85.1%) pod length (83.8%) and shell weight (69.6%) respectively. The low heritability was observed in number of seeds (61%), pod thickness (56.6%), vein weight (50.6%) and pod width (44.7%). Based on the results of this investigation the genotype PG1 has higher pulp weight and low seed weight per pod in comparison to all other genotypes. NO33 was found to be a superior for pod weight, pulp weight and pod length, but it has high seed weight. Hence this genotype can be used for cultivation and crossed with PG1 to decrease the seed weight. The genotypes ‘P13’ had high pulp weight, pod weight and low seed weight, thus can be released for large scale cultivation. The varieties were divided into ‘A’ (16) and ‘B’ (20) clusters at 19.5 linkage distance. The RAPD analysis revealed a moderate level of genetic diversity between 36 tamarind genotypes. AFLP markers are more efficient in identifying genetic diversity among tamarind genotypes.The present study indicated that the genetic diversity between tamarind genotypes was minimum (4.5%) between NCBS2 and NCBS3 while it was maximum (38%) between NCBS3 and P3. The study brought out clearly that all the 36 genotypes were clearly clustered into two main groups with a moderate to high level of genetic diversity. The percentage of polymorphic markers was lower for AFLP than RAPD markers (83.3% and 91.3% respectively). However, AFLP primers amplified on average six times more products than RAPD markers. The average numbers of polymorphic products per primer were 8.8 and 65.3 for RAPD and AFLP primers, respectively, i.e., AFLP primers were five times more efficient than RAPD primers in their ability to detect polymorphism in tamarind genotype. AFLP markers were also more effective in the detection of polymorphism among the closely related genotypes. Based on genetic diversity analysis using RAPD and AFLP, parental combinations like NCBS3 X P3, NCBS3 X NB1, NB1 X PKM1, P10 X NO33 and BTI X NO33 can be used successfully for future breeding programme. Also based on the RAPD and AFLP analysis, genetically closely associated genotypes groups such as ‘H3’ and ‘H4’, ‘S16’ and ‘S18’, ‘NO17’ and ‘H1’, ‘NCBS2’ and ‘NCBS3’, ‘BT3’ and ‘BT4’, ‘PKM1’ and ‘PKM2’, P3 and P10, PG2 and MG1, MG2 and MG3, and NCBS2 and NCBS3, can be avoided in future breeding programmes
