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.

ThesisItem Open Access STUDIES ON SEASONAL INCIDENCE AND LOSS ESTIMATION IN GUAVA DUE TO TEA MOSQUITO BUG, Helopeltis antonii Signoret (Hemiptera : Miridae)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, DHARWAD, 2000) Kumar; Sunil Krishna Naik, L"Investigations undertaken during 199 9-2000 at department of Agricultural Entomology, College of Agriculture, Dharwad. The survey carried out at MRS, Dharwad on two guava cultivars for seasonal fluctuations of Helopeltis antonii indicated that the pest incidence was at its peak during October both on young leaves (18.47%) and fruits (20.53%). No incidence was observed on flower buds during the study period on Cv. L-49. The peak infestation level on Cv. Navalur local was observed during September on young leaves (18.54%) and during December (8.62%) on flower buds. However, on fruits, it was observed during November (61.33%) and it vanished from February onwards. However on cashew (during off season) the peak incidence of the pest during December on young leaves was 11.98 per cent and on panicles (10.51%). On Cv. L-49, the pest incidence was at its peak during September (24.3%) at Navalur location on young leaves and on flower buds no incidence was observed excepting in December (0.79%). However, on fruits the highest incidence of 13.66 per cent was observed during September. On Cv. Navalur local the maximum incidence on young leaves was observed during September (17.94%) and no incidence was noticed on flower buds. During August 21.77 per cent incidence was observed on fruits. The desaping action by bug on fruits resulted in to necrotic lesion within a couple of hours and later on it resulted in scab formation. The dimension of such spots varied from 1.00 to 2.7 mm in diameter. The fruit infestation (8.98%) by the bug resulted in reduction in the monitory loss of Rs.4,691.28 per ha. Ascorbic acid, pectin, TSS content and weight of infested fruits reduced with the increase in infestation level. Whereas pH was highest at increased infestation level. The order of acceptance by the consumers was decreased as the level of infestation increased."ThesisItem Open Access EFFECT OF ORGANIC AND INORGANIC FERTILIZERS ON BANANA cv. RAJAPURI (Musa AAB)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, DHARWAD, 2003) Kumar; Bhavidoddi Rahul; Kanamadi, V C"An experiment was carried out on banana plant crop, cv. Rajapuri {Musa AAB) to study the effect of organic an3niorganic fertilizers on banana growth, maturity, yield and quality parameters in the All India Coordinated Research Project on Tropical Fruits located at Kittur Rani Channamma College of Horticulture, Arabhavi during November 2001 to December 2002. The treatment 100 per cent inorganic fertilizer alone recorded maximum plant height during initial period of growth upto 150 days after planting (DAP), whereas at later period of growth, treatment comprising 25 per cent N as FYM + green manure (sunhemp) + 75 per cent N as inorganic fertiliser recorded maximum plant height. Similar trend was noticed for other vegetative growth parameters such as pseudostem girth, number of functional leaves, leaf area and number of sucker production. Early shooting and harvesting was recorded in the treatment 25 per cent N as FYM + green manure (sunhemp) + 75 per cent N as inorganic. The highest bunch weight of 8.65 kg per plant (26.81 t/ha) was noticed in the above treatment. Similar trend was also observed for number of hands per bunch, number of fingers per hand, total number of fingers per bunch, finger length, finger girth, finger weight, pulp weight, peel weight, pulp to peel ratio, shelf life, TSS, TSS : acid ratio, reducing sugar, total sugar, N, P, K in leaf, yield per plot, yield per hectare, highest net returns and cost : benefit ratio. While lower values were recorded for acidity, non-reducing sugar, days taken for ripening, nematode population in soil and roots at bunching stage."ThesisItem Open Access SURVEY OF INDIGENOUS TECHNOLOGIES AND EVALUATION OF BOTANICALS AGAINST MAJOR STORAGE PESTS(SURVEY OF INDIGENOUS TECHNOLOGIES AND EVALUATION OF BOTANICALS AGAINST MAJOR STORAGE PESTS, 2004) Kumar; Sunil Naganagoud, A"The survey of indigenous storage technologies available in Hyderabad Kamataka (Gulbarga and Bidar districts) and the effect of few promising botanicals against two major stored grain pests on sorghum and chickpea under laboratory conditions were carried out at Agiicuiluiai College Raichur, Karnataka during 2002-03. Among the storage practices followed in the Hyderabad Kamataka region for cereals and pulses, sim drying was the predominant practice in Gulbarga and Bidar districts. The predominnnt storage structures used for storing cereals was gunny bags followed by hagevii and gunny bags for pulses. The sweet flag and malathion were found equally effective in minimum multiplication of !)olii Sitoplulus oiyznc and Callosohrucluis chincnsis on sorghum (2.50 and 1.00 adults/100 g of seed sample) and chickpea (1.50 and 1.00 adults/100 g of seed sample) respectively in the laboratory. Studies on seed mixing and storing along with various botanicals revealed that malathion and sweet Hag were found significantly superior up to 60 days. Botanical powders when dusted over cloth bags , the population build up was not noticed in malathion and sweet Hag treated bags in the beginning , later (after 60 days) incidence was noticed. The minimum seed d;iniage was in malathion, followed by sweet flag rhizome powder on sorghum and custard apple seed powder and sweet flag rhizome powder on chickpea. The germination was unaffected in these treatments in both seed ini.xing and dusting."
