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.

    Intergrated nitrogen management in maize (Zeamays L.) in a vertisol of malaprabha command area
    (UAS, Dharwad, 2007) N.Mamatha; H.T.Channal
    yield and certain quality parameters of cotton in vertisol, under irrigated condition during kharif 2006-07, at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experiment consisted nine treatments with three replications and was laid out in randomized block design. The results indicated that different levels of sulphur, iron, zinc and their combination significantly increased the seed cotton yield, ginning percentage and seed index. Among the sulphur levels (as factomphos), application of 50 kg S per ha, recorded the highest seed cotton yield (19.50 q/ha), ginning percentage (43.00%) and seed index (9.10) and were par with the 25 kg S per ha and was significantly superior over control. Among the iron levels (as FeSO4), application of 50 kg Fe per ha recorded the highest seed cotton yield (18.50 q/ha), ginning percentage (39.10%) and seed index (9.00) and was significantly higher over control. Among the levels of zinc (as ZnSO4) application of 50 kg Zn per ha, recorded the highest seed cotton yield (20.50 q/ha), ginning percentage (39.50%) and seed index (9.10) and on par with application of 25 kg per ha and was significantly superior over control. Combined application of sulphur, iron and zinc each at 50 kg per ha (T9) recorded the highest seed cotton yield (98.50 q/ha), ginning percentage (43.00%) and seed index (9.81) which were on par with treatment (T8) receiving sulphur, iron zinc each at 25 kg per ha and was significantly higher over rest of the treatments. The treatment T9 recorded the highest nutrient uptake (N, P, K, S, Fe and Zn) and on par with the treatment T8 and was significantly superior over rest of the treatments. Further, combined application of sulphur, iron and zinc each at 25 kg per ha recorded the highest B:C ratio of 2.51 and net returns of Rs.33,396 proved to be economically more feasible.

    Response of maize (zea mays l.) to ferti-irrigation of spentwash
    (UAS, Dharwad, 2007) Tara Devi Bhukya; S.G.Patil
    A field experiment was conducted at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif, 2006 to study the response of maize to ferti-irrigation of spentwash. The design adopted was Randomized Block Design with seven treatments replicated thrice. In the investigation spentwash was included as a replacement for chemical fertilizer. It was used on the basis of nitrogen requirement and applied as recommended. Spentwash application improved all the growth parameters including plant stand, leaf number, leaf area, chlorophyll content etc. Spentwash had a significant effect on most of the yield parameters. Both growth and yield parameters complemented each other in realizing higher fodder and grain yield. Application of spentwash at the recommended N level remained comparable with chemical fertilizer providing on opportunity of substituting. The economics of crop cultivation was significantly in favour of spentwash rather than chemical fertilizer as it resulted in direct saving of fertilizer cost. Spentwash application at the recommended level (N requirement) did not affect the soil properties. Both pH and EC remain unaffected although a marginal increase in conductivity and organic carbon, available N, P were observed but increase in K was perceptible with no impending immediate ionic interaction when applications are not repeated beyond three seasons. Spentwash application had a favourable effect on pH, conductivity, available nutrients and did not favour their accumulation. Spentwash helped in better nutrition as it also supplemented micronutrients. It did not suppress biological activity and no significant changes was observed in them due to spentwash use.

    Export performance and competitiveness of ginger from India
    (UAS, Dharwad, 2006) W.J.Thanuja; H.S.S.Khan
    India is rightly called as “spice bowl of the world” for its production of variety and superior quality of spices. In the area of export ginger occupies fifth position in terms of quality and sixth position in export earnings among the spices. The main competitors to India are China, Indonesia and Thailand. The main importers are Pakistan, Saudi Arbia, USA and Netherlands. A study conducted to analyze export performance and competitiveness of ginger from India with the objectives like trends in domestic and International prices of ginger, direction of trade of ginger export and impact of withdrawal of freight subsidies on export. Karnataka, Kerala, and Tamil Nadu markets were selected to study the market integration and export of ginger from Cochin port. The required data collected for the period of 20 years. The objectives are analyzed with trend, nominal protection coefficient, and markov chain and growth rate analysis. The international prices of Cochin ginger were found to be decreased in I and III phase and increasing in II Phase. An average NPC value over 20 years for the domestic market price was 0.70 indicated moderate competitiveness in the international market. Pakistan and Saudi Arabia were found to be highly loyal markets for Indian ginger indicated by the retention of their previous shares of exports from India. The growth rate between pre and post-WTO period in terms of area and production were positive. The export growth between pre and post WTO period in terms of quantity and values were found to be declining and negative. The correlation analysis revealed that the selected markets in three states were well integrated and the pair of Bangalore-Trivendrum market was highly integrated.
