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.

    BIOCHEMICAL STUDIES ON RICE {Oryza sativa L.) CULTIVARS FOR NUTRITIONAL EVALUATION
    (University of Agricultural Sciences GKVK, Banglore, 2013-03-05) R. DRUVASHREE; R. CHANDRU
    Rice cultivation is improving in India with the release of number of varieties and hybrids. An investigation was undertaken to evaluate the physico chemical properties, biochemical composition and nutritional qualities of selected eight rice varieties viz., BPT-5204, IR-64, Jyothi, KRH-2, MAS-946, Thanu, Karimundga and KRH-4. Rice cultivars differed significantly in respect of milling characteristics which is reflected by the significant differences of the rice cultivars with respect physical characteristics like length, breadth, test weight, chalkiness etc. Rice varieties Thanu and Jyothi had significantly lesser cooking time (20 minutes) compared to all other varieties/hybrids which took 25 minutes for cooking. The rice cultivars differed significantly with respect to swelling ratio by weight and it ranged from 3.73 to 4.41, hybrids such as KRH-2 and KRH-4 had higher swelling ratio by weight. Physical characteristics of grains, physicochemical and functional properties of flour was estimated. The investigation revealed variations in most of the parameters studied. Variation in size of the grain, weight and density was evident. Oil absorption capacity was highest in KRH-2 (2.1%) and hydration capacity was highest in Sharada (0.9%). The crude fat content varied from 0.27-1.67 per cent. BPT-5204 was found to have high protein about 8.27%. Studies on in vitro protein digestibility revealed highest digestion in BPT-5204 (92.91%) and least digestion in KRH-2 (71.1%). Starch content varied between 42.61 to 55.98% and amylose content varied between 29.23 to 38.1%. Starch digestibility was highest in Karimundga (47.44%) and least in Sharada (31.39%).

    (University of Agricultural Sciences GKVK, Bangalore, 2013-09-15) HADAGALI, VISHWANATHA.; MANJUNATHA, B. N.
    The present study was carried out during 2012-13 in Bellary and Koppal districts of Karnataka. A total of 120 respondents were selected by random sampling from 10 villages and data was collected by personal interview method. The results of the study revealed that, a larger number of rural youth studied up to PUC (31.66 %), had medium sized land holding (45.84 %), medium annual income (45.50 %), and nuclear family (65.83 %). Most of the farm youth had medium cosmopoliteness (67.50 %), extension contact (45.00 %), extension participation (46.66 %) and risk orientation (37.50 %). A good number (42.50 %) of rural youth had high level of mass media utilization and innovativeness (40.00 %).Nearly one-third (36.67 %) of rural youth had high level of aspirations in agriculture, followed by sericulture (40.00 %), horticulture (43.75 %) and medium level of aspirations in dairy (47.05 %). A good number (40.00%) of rural youth had high participation in agriculture followed by dairy (45.45%) and medium participation in horticulture (40.00 %) and sericulture (40.00%). Scarcity of labour (74.16%), inadequate and untimely supply of fertilizers and plant protection chemicals (69.16%), lack of required finance and untimely availability of credits/subsidies (67.50%) were the important problems. Supply of power to irrigation pumps at least for 12 hours (72.50 %), timely supply of fertilizers and plant protection chemicals (66.66%) and timely supply of seeds/ planting material/breeds/species (64.16%) were the suggestions expressed by the rural youth to overcome these problems in agriculture and allied activities.

    DEVELOPMENT OF READY-TO-EAT HOT EXTRUDED PRODUCTS FROM FOXTAIL MILLET
    (University of Agricultural Sciences GKVK, Bangalore, 2013-07-12) AMRUTH KUMAR, M. A.; Palanimuthu, V.
    Small millets though contain more fibre and many bioactive compounds, their utilization as food is confined to traditional consumers mainly due to non-availability of consumer friendly products. Hence, a study was conducted to develop ready-to-eat hot extruded kurkure products using different small millets with foxtail millet as base and a laboratory twin screw extruder was employed. As a prelude, nutritional composition (moisture, protein, fat, fibre, ash and carbohydrates) including micronutrients (iron, copper, sodium, zinc, magnesium, manganese) of five millets (foxtail, little, barnyard, proso and kodo) and Bengal gram were analyzed. Among 20 foxtail millet based kurkure ^ n ^ U!no/Ā°I!not/ ? ted^ fĀ° Ur formulations namely, Foxtail:Bengalgram:Proso ( /0.IO/0.IO/0), Foxtail:Bengalgram: Little (80%: 10%: 1 0 %)- Foxtail: Ben galgram: Barny ar d (60%: 10%:30%); and Foxtail:Bengalgram:Kodo (80%: 10%: 10%) were found to be veiy good and the first formulation was adjudged to be best based on sensory evaluation. 7 Trials were conducted to optimize process and extruder operating parameters. Based on physical parameters of extrudates (expansion ratio, water solubility index, water absorption index, bulk & true densities, tri-stimulus colour and texture), millet grit size (1201-592 jim) formulation moisture content (14-18%), extruder barrel temperature (110 C) and screw speed (350 rpm) were found to be optimum. Among two packages tested for storage of millet kurkure, with and without nitrogen flushing, Polyethylene Coated Aluminium film package flushed with nitrogen was found to be better compared to LDPE film and kurkure could be stored for over two months at ambient conditions without any quality deterioration. The Cost:Benefit Ratio for manufacturing foxtail millet based kurkure was 1:1.72 and therefore, can be recommended for commercial exploitation.

    BIOLOGY AND MANAGEMENT OF PAPAYA MEALY BUG, Paracoccus marginatus WILLIAMS AND GRANARA DE WILLINK (HEMIPTERA: PSUEDOCOCCIDAE) INFESTING MULBERRY
    (University of Agricultural Sciences GKVK, Bangalore, 2013-08-05) PRADEEP KUMAR, K.; Ramakrishna, Naika.
    Karnataka were surveyed for the incidence of Paracoccus marginatus Willliams and Granara de Willink and its natural enemies. Maximum infestation was observed in Bengaluru urban (4.00) followed by Mysore (3.50), Mandya {3.25) and Chamarajanagara (3.00) districts. Fourty six plant species belonging to 25 botanical families were recorded as hosts of the mealy bug. Further, three parasitoids and four predators were recorded on mealy bug in mulberry eco-system. Eight species of ants belonging to three subfamilies were found attending to P. marginatus. The study also revealed variation in the life cycle parameters of P. marginatus on three varieties of mulberry. The female mealy bug exhibited three nymphal instars, without any pupal stage, while the male had three nymphal instars and a pupal stage. On an average the fecundity was highest on V1 (699.20) followed by S3& (661.00) and Ms (643.30). The incidence of P. marginatus on mulberry was first observed during 2nd week of November,2012, later the incidence gradually increased to 20.25 mealy bug/ 10 cm shoot length in March,2013 and then on wards its population declined further. Pest population was significantly positively correlated with maximum temperature (r= 0.517**) and sunshine hours (r=0.660**), and negatively correlated with rainfall (r= -0.268), morning (r= -0.156) and afternoon (r= -0.611**) relative humidity. Among the biorational forrrrnlations sprayed on mealy bug, NSKE@ 2.5ml, 5ml, 10ml significantly decreased the survival of mealy bug population (15.32, 12.77, 7.00 No./plant) and highest reduction in pest population (67.60, 76.09, 82.49 %) at low, medium and high dosage, respectively, at 72 hours after treatment.

    (University of Agricultural Sciences GKVK, Bangalore, 2013-11-20) VIVEK, B. C.; Lohithaswa, H. C.
    An investigation was carried out at ZARS, V.C. Farm, Mandya; ARS, Bavikere and Farmer's field, Yatnahalli village, Ranibennur Tq. to analyze the morphological and molecular (SSR) diversity, combining ability of inbreds and stability of hybrids for 16 morphological characters during kharif 2012. Pooled analysis of variance revealed significant differences among 100 inbreds and 225 hybrids for all the 16 characters. One hundred inbreds were grouped into 10 clusters and cluster I (48) accommodated maximum number of inbreds. The character days to brown husk contributed highest for total divergence and the inbred MAI- 706 recorded highest mean values for more number of characters. At the molecular level, inbreds were grouped into seven clusters and cluster III was the largest with 35 entries. A total of 213 SSR alleles were detected and the marker umc2078 sampled highest number of alleles and maximum PIC was observed for umcl542. There was no agreement between morphological and molecular diversity. Predominance of additive genetic variance was noticed for characters grain yield, test weight, grain rows per cob, cob length and cob girth. The inbreds LM-13,V-1712-1, V-1154 and CIMMYT-5 were good general combiners and the crosses MAI-117 x LM 13, Z-62-67 x MAI 105 and Z-62-55 x LM 13 were good specific combiners.The crossesCIMMYT-5 x LM 13, LTP-1 x SKV 50 and CIMMYT-5 x SKV 50 manifested significant standard heterosis for highest number of characters.The test hybrids V-2232 x MAI 105, V-1649 x MAI 105, CIMMYT-5 x LM 13, V-1712-1 x MAI 105, Z-63-30 x LM 13, V-632-112 x LM 13, V-1168 x LM 13, V-291-2 x LM 13, V-632-67 x LM 13, CML-172 x MAI 105, V-1154 x LM 13, V-241-2 x LM 13, CIMMYT-47 x LM 13, Z-51-1 x LM 13, HKI-193-1 x LM 13, V-2232 x LM 13 and V-1649 x LM 13 were stable with high grain yield and could be further evaluated for confirmation of their superiority.

    (University of Agricultural Sciences GKVK, Bangalore, 2013-07-21) MANJUNATHA, A. L.; Ramegowda, P. V.
    The study was conducted on Performance of Food Processing Special Economic Zone for the year of 2012-13 in Hassan district of Karnataka. The objectives of the study are to examine the Project planning and implementation of Food Processing Special Economic Zone, to assess the level of farmer's participation and benefits realized through Special Economic Zone and to document the constraints in implementation of Hassan Food processing Special economic Zone (HFPSEZ). The data was collected from 5 companies and 60 farmers. Descriptive statistics, percentage and Garret ranking tools were used to analyse the data. The findings of the study indicated that only few companies started business and there was delay in implementation of the HFPSEZ. The farmers involved in the production of cereals, pulses, fruits, vegetables and plantation crops are not participating in the HFPSEZ. Eighty three per cent of farmers interested to participate in the HFPSEZ in future and 71.42 per cent the farmers expressed the interest in contract farming with the companies. The problems encountered by HFPSEZ are non availability of raw material throughout the year which was the major problem, non availability of skilled labour, electricity and water in the project area were the other constraints. These problems could be addressed by the government and promoters. The promoters have to invite new compames and encourage farmers participation.
