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.

    EFFECT OF HUMIC ACID BASED LIQUID NUTRIENT FORMULATION ON SOIL BIOLOGICAL PROPERTIES, GROWTH AND YIELD OF PADDY (Oryza sativa L.), MAIZE (Zea mays L.) AND TOMATO (Lycopersicon esculentum Mill.) UNDER FIELD CONDITION
    (University of Agricultural Sciences, Bangalore, 2022-12-06) LAVANYA, S M; MUTHURAJU, R
    The present study was carried out to understand the effect of different humic acid basedliquid nutrient formulations and humic acid coated fertilizers on soil biological properties,growth and yield of paddy, maize and tomato under field condition. Application of the humicacid based liquid nutrient formulations i.e., Product 1 @ 2.0 l/acre stimulated significantlyhigher population of free-living nitrogen fixers in paddy (9.64×104 CFU/g), maize (9.69×104CFU/g) and tomato (9.99×104 CFU/g) rhizosphere. Further, highest dehydrogenase enzymeactivity in paddy (124.52 μg TPF/g/h), maize (126.07 μg TPF/g/h), tomato (151.25 μg TPF/g/h)and microbial biomass carbon and nitrogen in paddy (402.43 and 46.95 μg/g of soil), maize(455.26 and 53.11 μg/g of soil) and tomato (446.41 and 52.08 μg/g of soil) rhizosphere wasobserved in treatment that received the Product 1 @ 2.0 l/ac. Application of humic acid coatedfertilizer recorded increased plant height (128.19 cm), number of tillers (24.81/plant), numberof panicles per plant (19.38), grain yield (31.76 q/ha) in paddy, highest seed weight at harvest(124.94 g), grain yield (64.91 q/ha) in maize and highest plant growth parameters, highestnumber of fruits per plant(19.52), fruit weight per plant (8.70 kg) and fruit yield (66.13 q/ha) in tomato. It is evident from the data obtained in the field experiment involving paddy, maize andtomato that application of humic acid based liquid nutrient formulation product 1 @ 2.0 l/acreenhanced the biological properties of rhizosphere soils, growth and yield of these cropscompared to the soil which received inorganic fertilizers.
