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.

    INFLUENCE OF LONG TERM FERTILIZER APPLICATION ON THE AVAILABILITY OF MICRONUTRIENTS UNDER FINGER MILLETMAIZE CROPPING SEQUENCE.
    (University of Agricultural Sciences GKVK, Banglore, 2007-10-05) ATHEEFA, MUNAWERY; N. VASUKI
    reference to the micronutrient availability and extent of removal through crop uptake under different fertilizer management practices. The results revealed that the application of 100% NPK with FYM and 100% NP and N alone recorded significantly higher available zinc, copper and manganese respectively. While, application of 100% NPK (S-free) recorded higher available iron. The study on periodical changes in available micronutrients due to long-term fertilization indicated that available Zn, Cu and Mn decreased. While, Fe increased significantly over the years. The above micronutrients decreased with depth in all the treatments. Significant negative correlations were observed between available micronutrients and pH, organic carbon, exchangeable Ca and Mg but positively with exchangeable acidity. Positive correlation of available phosphorus was recorded only with available Zn.

    STATUS AND REVALIDATION OF POTASSIUM REQUIREMENT FOR FINGER MILLET-MAIZE CROPPING SEQUENCE IN EASTERN DRY ZONE OF KARNATAKA
    (University of Agricultural Sciences GKVK, Bangalore, 2013-12-12) ATHEEFA, MUNAWERY; RAMAKRISHNA PARAMA, V. R.
    Potassium is an essential nutrient for growth and development of crops, which is being depleted in Indian soils due to very low applications. The present study conducted during 2010-11 on Alfisol addresses the above issue. Field and pot experiments were carried out to determine the effect of graded levels of potassium on growth and yield of crops and soil properties under nutrient gradient strips and to revalidate the optimum dose of K required for maize in soils of eastern dry zone of Karnataka where K status was low to medium. Field experiments indicated higher grain yield (3287.67 and 7762.00 kgha-1 respectively) in-case of fingermillet and maize was recorded in T6 (200%K+Rec.NP+FYM) of very high K fertility gradient strip (K4). High major, secondary and micronutrients in soils with increase in potassium fertility gradients (K0 to K4). Calcium and magnesium decreased from Control (T1) to treatment T7 (200%K+Rec.NP). A comparison of K added and taken-up which is referred to as K balance indicated a negative value in-case of (T1, T2, T4 and T6) in very low K gradient (K0) whereas (T1, T2, T3 and T5) recorded negative value in low K gradient (K1) strip respectively, this was in-case of fingermillet whereas in maize T1 of K0 gradient recorded negative K balance, all other treatments in other K fertility gradients recorded positive balance. Water soluble, exchangeable, non-exchangeable and total potassium in soil after fingermillet–maize sequence increased with increase in levels of potassium application. Results of pot experiment indicated critical limit of 105 kg K ha-1 for soil available K and 1.72% plant K for maize crop. The soil available K can be revalidated as <105 kg ha-1 very low, 106 to 215 kg ha-1 low, 216 to 380 kg ha-1 medium and >380 kg ha-1 as high in available K respectively.
