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 STCR TARGETED YIELD APPROACH ON RAGI CROP YIELD, SOIL PROPERTIES, NUTRIENT UPTAKE AND NUTRIENT USE EFFICIENCY
    (University of Agricultural Sciences GKVK, Banglore, 2007-09-17) ASHWINI, Y.; P.K. BASAVARAJA
    A field experiment was conducted on Alfisols during 2006-2007 of Zonal Agricultural Research Station, GKVK, UAS, Bangalore to evaluate the different methods of nutrient application in comparison with the STCR approach on ragi crop (GPU-28), yield, soil properties, nutrient uptake and nutrient use efficiency. The result revealed that application of N,P,K nutrients for a soil test crop response (STCR) targeted yield of 50 q ha"' through 50 % inorganic + 50 % organics recorded a highest gr^in yield of (3638.9 kg ha"') and straw yield of (5740.6 kg ha"'). Similarly application of N,P,K nutrients through 50 % inorganic + 50 % organics for a targeted yield of 60 q ha"' recorded highest N, K, S, Ca, Mg content in the soil. However, available P status was highest where STCR target of 50 q ha"' was fixed by application of 50 % inorganic+ 50% organics sources of nutrients. Higher values of N, P, Ca, S uptake by ragi grains and straw was noticed with 50 % inorganic + 50 % organic sources of nutrient application for a targeted yield of 50qha"' except Mg K, uptake by ragi grains and straw which has recorded higher values due to application of N, P, K nutrient through 50% inorganic 50% organic sources of nutrients for a targeted yield of 60 q ha"'. , However, the NUE was highest where nutrients were applied as per POP followed by nutrienti applied for a targeted yield of 50 q ha "' through conjunctive use of Organic and inorganic sources of nutrients. This higher NUE by ragi crop as per package clearly indicates that nutrients were applied in a well balanced manner but still STCR approach was better for achieving the higher yields

    PERSISTENCE AND DEGRADATION OF CHLORPYRIFOS IN SELECTED COFFEE GROWING REGIONS OF KARNATAKA
    (University of Agricultural Sciences GKVK, Banglore, 2008-09-19) REMYA, A.; Dr. N.P PRAKASH
    Chlorpyrifos, (O, 0-diethyl O- (3, 5, 6-trichloro-2-pyridyl) phosphorothioate) is the world's leading insecticide being consumed in large volume and is effective against a wide range of plant feeding, household and soil insects. Kamataka is a major commercial coffee growing state in India with Chikmagalur and Madikeri being the major producing areas. Incidence of white stem borer is a serious threat to Arabica coffee productivity for which Chlorpyrifos 20 EC was recommended by Coffee Board in 2004. A study was undertaken to know the persistence and degradation of chlorpyrifos at two different moisture conditions (field capacity and submergence), lime treatments (4 and 8 tha"') and fortification levels of 10 and 25 pg g"' in both Chikmagalur and Madikeri soils. Higher persistence of chlorpyrifos was noticed at higher fortification level. The degradation of chlorpyrifos was faster in Chikmagalur soil compared to Madikeri soil at both moisture regimes irrespective of the fortification levels. Degradation of chlorpyrifos decreased with increased moisture content from field capacity to submergence. The order of chlorpyrifos degradation observed in lime treated soil was 8 t ha"' > 4 t ha"'> 0 t ha"'. Half-life of chlorpyrifos ranged from 11.1 to 22.8, 9.6 to 20.2 and 7.4 to 11.8 days at the lime treatment rates of 0, 4 and 8 t ha"' days in Chikmagalur and 14.7 to 27.5, 10.9 to 23.6 and 8.2 to 14.7 days in Madikeri soils respectively at field capacity. A laboratory study on the effect of chlorpyrifos on dehydrogenase and phosphatase enzyme in soil indicated a slight inhibitory effect on both the enzymes. Residue analysis of chlorpyrifos in selected coffee orchard soils, water and soils of nearby rice fields showed the persistent nature of chlorpyrifos even in field condition.

    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.

    DYNAMICS OF PHOSPHORUS IN ACID SOILS OF NORTH KARNATAKA
    (University of Agricultural Sciences GKVK, Banglore, 2007-09-01) SHEELA, B. S.; B. BASAVARAJ
    A survey and an incubation study were carried out for a cluster of villages of Sirsi taluk to study the dynamics of phosphorus in soils. The soils of the survey area are acidic in nature, low in salt content, medium to high in organic matter content, high in crystalline Fe and A1 and amorphous Fe and Al. Reductant soluble P is the dominant P fraction among the P fractions. Saloid P is the least P fraction among the P fractions. The content of available P ranged from low to medium. Incubation study revealed that saloid P values were found to increase during initial period of incubation but later decreased in all the treatments and higher values were recorded in P as DAP. Calcium P values were found to increase significantly in all the treatments and highest were recorded in P as phosphatic fertilizer + lime. Reductant soluble P values were found to decrease in all the treatments. Occluded P values were found to increase during initial period of incubation but later these values were found to decrease in all the treatments.
