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.

    EVALUATION OF LIGNITE AND POULTRY MANURE BASED HUMIN ON SOIL PROPERTIES AND CROP PRODUCTIVITY
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-12-27) CHANDRAKANT; KADALLI, G. G.
    A green house study was carried out to evaluate the lignite (LH) and poultry manure (PMH) based humin on soil properties and crop productivity in three different soils (acid, neutral and alkali soil) with baby corn as test crop during 2018. A field experiment was also conducted in acid soil consisting of ten treatments replicated thrice in a RCBD with maize as main crop and cowpea as residue crop at KVK, Hadonahalli, Bengaluru Rural district during 2018-19. The per cent recovery of humin was higher from poultry manure (86.70%) than lignite manure (64.52%).The PMH recorded higher nutrient content than the lignite humin. In green house study, the performance of both humins was better in acid soil compared to neutral and alkali soils. At 60 days after sowing, significantly higher fresh and dry biomass of baby corn (53.94 and 42.90 g plant- 1, respectively) were recorded with T2 (FYM @10 t ha-1) which was followed at par with T7 (PMH @2.5 t ha-1 +FYM @7.5 t ha-1), T3 (LH @2.5 t ha-1 +FYM @7.5 t ha-1) and T8 (PMH @5 t ha-1 +FYM @5 t ha-1). In all treatments 100% RDF was commonly applied except control plot. In field experiment, significantly higher maize kernel (8070 kg ha-1), stover (9948 kg ha-1) and nutrient uptake was recorded with T2 and it was followed at par with T7, T3 and T8. Similar effect was recorded in cowpea residue crop. There was significant increase in available nutrient status in post harvest soils. Hence, it can be concluded that humin manures of poultry manure and lignite can be effectively utilized as alternative source of organic manure to the tune of 5 and 2.5 t ha-1, respectively without any detrimental effect on crop productivity and also on soil health especially for acid and neutral soils.

    Mapping quantitative traits loci, and prediction and validation of genomic estimated breeding values for seed yield and its component traits in dolichos bean (Lablab purpureus L. Sweet)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-04-02) CHANDRAKANT; Ramesh, S.
    DNA marker-assisted identification and introgression of the key quantitative trait loci (QTL) into elite genetic background effectively complement phenotype-based selection and help enhance pace and efficiency of breeding crops, dolichos bean being no exception to this. The linkage map was constructed using genotypic data of 58 polymorphic SSR markers (after excluding 2 markers exhibiting significant segregation distortion and 31 markers which did not fit to the threshold recombination frequency of 0.3, on 109 F10 recombinant inbred lines (RIL) derived from HA 4 × CPI 60125 (HACPI 6). At LOD 2.0, 58 markers among 91 polymorphic markers were mapped on to 11 linkage groups (LG). The total length of the map spanned 2008.55 cM with an average density of 34.63 cM. Five QTLs, one controlling days to 50 % flowering, two each controlling dry seed yield plant-1 and test weight were detected based on each of the three years’ (Kharif-2014, Kharif-2015 and Kharif-2016) as well as three-years average quantitative traits data. One common QTL flanked by KTD 250 and LABT 2 with a distance of 37.69 cM controlling test weight was detected at 154 cM on LG 6 across Kharif-2014, Kharif-2015 and three-year’ average data. Another common QTL flanked by LABT 25 and LABRRT 43 with a distance of 41.12 cM controlling days to 50% flowering was detected at 41 cM on LG 9 across Kharif-2016 and three-year’ average data. The linkage of LABRRT 36 with QTL controlling days to 50 % flowering; KTD 63 with raceme length; LABRRT 36 with pods plant-1 and LABRRT 35 with dry seed yield plant-1 in HACPI 6-derived RIL population was confirmed in HACPI 3-derived RIL population. It is proposed to saturate the linkage map (of HACPI 6), confirm and validate the identified QTL for use in marker-assisted dolichos bean breeding.
