University of Agricultural Sciences, Dharwad

The University of Agricultural Sciences, Dharwad was established on October 1, 1986. The University has 5 Colleges, 27 Research Stations, 6 Agriculture Extension Education Centers, 6 Krishi Vigyan Kendras and ATIC. The University has its jurisdiction over 7 districts namely Bagalkot, Belgaum, Bijapur, Dharwad, Gadag, Haveri, and Uttar Kannada in northern Karnataka. Greater diversity exists in soil types, climate, topography cropping and farming situations. The jurisdiction includes dry-farming to heavy rainfall and irrigated area. Important crops of the region include sorghum, cotton, rice, pulses, chilli, sugarcane, groundnut, sunflower, wheat, safflower etc. The region is also known for many horticultural crops. Considerable progress has been registered in the field of education, research and extension from this University.

    Studies on effect of moisture conservation measures and nutrient management on growth of pongamia pinnata in varada watershed area
    (UASD) Kotresh S.; Mallikarjunappa Gowda
    Soil and moisture conservation measures are one of the most important factors for the improvement of degraded lands. The rainy season is usually short but occasional rainfall can take the storm of heavy surface runoff. Moisture conservation measure is to achieve the maximum cultivated soil for the survival and growth of trees. There is need to diverse suitable techniques of moisture conservation measures and nutrient management. A field experiment was carried out at Karjagi of Haveri taluk during 2012-2013 On “Moisture conservation measures and nutrient management on growth of Pongamia pinnata with Ring basin, Crescent bunds, control and organic manures as Vermicompost (2.5 t/ha), FYM (5 t/ha) and Glyricidia (1.25 t/ha) and also inorganic fertilizers 100:50:100 N: P2O5:K2O kg/ha and 150:75:150 N: P2O5: K2O kg/ha. Significantly maximum plant height was observed in Ring basin + Vermicompost @ 2.5 t/ha + 150:75:150 N, P2O5, K2O kg/ha was recorded significantly higher plant height (3.62 m) at 12 months after treatment. Collar diameter (4.04 cm) and crown diameter (2.54 m) recorded significantly higher in ring basin at 12 months after treatment. Significantly maximum number of branches was observed in Ring basin + Vermicompost @ 2.5 t/ha + 150:75:150 N: P2O5:K2O (34.13). In ring basin + Vermicompost @ 2.5 t/ha + 150:75:150 N, N: P2O5:K2O had recorded significantly higher on organic carbon (0.82), pH (5.89), available nitrogen (318.45 kg/ha) and phosphorous (28.45 kg/ha) potassium (185.60 kg/ha) over the other treatment.
