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.

    Response of Tomato (Solanum lycopersicum L.) to Homa Organic Farming Practices
    (UAS, Dharwad, 2011) Brunda R.; P.W. Basarkar
    A field experiment laid out in completely randomised block design with 11 treatments exposed to Homa atmosphere replicated thrice was conducted during kharif 2010 to study response of tomato (solanum lycopersicum L.) to homa organic farming practices. The conventional control (CC) and control without Homa (CWH) were maintained almost 1 km away. The soil type was sandy loamy. All the seedlings were grown on raised beds, transplanted after one month and were given fresh cow dung and cow urine as basal treatment except absolute control, CC and CWC. Nonhoma ash was collected after burning the agricultural waste. Agnihotra homa (AH) was performed at sun rise and sun set and Om Tryambakam homa (OTH) was performed for 3-4 h daily during experimental period which yielded smoke and ash. A special bio-digester called Gloria Biosol was prepared which contained AH ash. The Non-homa ash, AH ash, OTH ash and Gloria Biosol were used for soil and foliar application. Soil and foliar application of Gloria Biosol was significantly superior over organic control in plant height, number leaves, number of branches, root length, yield attributes, microbial population in the soil, increase in the activities of soil dehydrogenase (5-52%) and soil phosphatase (2-34%), soil N and K and micronutrients, Cu and Mn and quality parameters like lycopene (40.69%), phenol (7.28%), ascorbic acid (49.05%), TSS (10.2%) and total sugar (9.68%) showed significant increase. Soil and foliar application of AH ash increased soil phosphorus and micronutrients, Zn and Fe. Shelf life of tomato fruits increased by 7-12 days due to different homa treatments as compared to organic and conventional control. Incidence of Leaf spot and insect attack was reduced significantly (37.2% - 40.17%, respectively) due to soil and foliar application of Gloria Biosol which was superior over homa ashes and control.
