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.

    Investigations on Planting Methods and Nutrition on Growth, Yield and Quality of Vetiver (Vetiveria zizanioides (L.) Nash)
    (University of Agricultural Science, Dharwad, 2017-06) Raviprasad Sajjan M.; Venugopal, C.K.
    A field investigation was conducted to evaluate the effect of planting methods and nutrition on growth, yield and quality of vetiver (Vetiveria zizanioides (L.) Nash Syn. Chrysopogan zizanioides) during July 2015- July 2016 at the Medicinal and Aromatic Plants Unit, Saidapur Farm, University of Agricultural Sciences, Dharwad, Karnataka. The experiment was laid out in split-plot design with three main plots (planting methods viz., P1– Ridge and furrow method, P2– Bed method and P3– Bag method) and six sub-plots (fertilizer levels viz., F1- 25:25:25 NPK, F2- 50:25:25 NPK, F3- 75:25:25 NPK, F4- 25:50:25 NPK, F5- 50:50:25 NPK and F6- 75:50:25 NPK kg/ha) comprising of eighteen treatment combinations replicated twice. Planting methods and nutrition levels had significantly influenced all the growth and yield parameters. Among the planting methods, bag method (P3) recorded significantly higher yield parameters viz., root length (50.12 cm), number of roots per plant (316.97), fresh root weight (219.15 g/plant), dry root weight (95.06 g/plant), root yield per ha (4,085.78 kg/ha) and essential oil yield (85.34 kg/ha) compared to other planting methods. Among fertilizer levels, 75:50:25 kg NPK per ha (F6) recorded significantly higher root length (45.98 cm), number of roots per plant (260.97), fresh root weight (177.28 g/plant), dry root weight (86.32 g/plant), root yield per ha (3,453.19 kg/ha) and essential oil yield (73.32 kg/ha) than all other lower levels of fertilizers at 12 months harvest. Among interactions, the combination of P3F6 (Bag method with fertilizer levels of 75:50:25 kg NPK/ha) recorded significantly higher root length (55.91 cm), number of roots per plant (350.4), fresh root weight (238.30 g/plant), dry root weight (103.29 g/plant), dry root yield (4.33 t/ha) and essential oil yield (94.25 kg/ha) compared to all other interactions. The same treatment combination also registered maximum gross returns (Rs.5,63,357/ha), net returns (Rs. 4,15,295/ha) and B:C ratio (1:3.80).

    Heterosis and Combining Ability Studies in Onion (Allium cepa L.)
    (University of Agricultural Science, Dharwad, 2016-09) Basavana Gowda G.A.; Patil, R.V.
    An investigation was conducted in the Department of Horticulture, College of Agriculture, Dharwad to study the heterosis and combining ability studies in onion (Allium cepa L.) with the objectives of identifying good general combiners and to assess the magnitude of heterosis for seventeen characters and to know the performance of hybrids. In the present investigation 54 entries have been evaluated (13 parents : 40 hybrids : 1 commercial check). Performance of hybrids like GKD-75 x Line-13 (11.83 t/ha), Kumata local x Line-13 (10.57 t/ha), ASKO-1201 x Cross-5 (9.60 t/ha) and Kumata local x cross-5 (8.88 t/ha) for the marketable yield was better than commercial check – Bhima Shakti (6.55 t/ha). These expressed considerable magnitude of heterosis over commercial check for yield. The top yielding entries [GKD-75 x Line-13 (4.013), ASKO-1201 x Cross-5 (2.431) and Kumata local x Line-13 (2.258)] involved positive (significant) x positive (significant) general combiner. Variance due to GCA and SCA was significant for the yield trait, indicating the involvement of both additive and non additive gene action. However, the estimates of SCA were higher than GCA variances indicating predominance of non-additive gene action in controlling the inheritance of this trait during kharif season. Marketable yield is the ultimate and most important trait. The performance of hybrids for marketable yield point to entries like ASKO-1299 x GKD-77 (26.80 t/ha), ASKO-1201 x Line-13 (26.25 t/ha), Bhima Shakti x Line-13 (26.25 t/ha), ASKO-1201 x GKD-77 (26.20 t/ha) and Bhima Shakti x cross-5 (24.65 t/ha) are statistically at par with commercial check [Bhima Shakti (24.6 t/ha)]. Expressed considerable magnitude of heterosis over commercial check for yield. For marketable yield, significant positive SCA effect for this trait was exhibited by cross ASKO-1299 x GKD-77 (5.602) which involved positive (non significant) x positive (significant) general combiner. This was followed by Bhima Shakti x Line-13 (5.207) which involved negative (significant) x positive (significant) general combiner. Variance due to SCA was significant indicating the involvement of non additive gene action during rabi season.

    Effect of Integrated Nutrient Management in Cherry Tomato (Solanum lycopersicum var. cerasiforme) Under Shade House Condition
    (University of Agricultural Science, Dharwad, 2016-07) Atapatakar, Babu; Patil, S.S.
    A experiment was conducted in the shade house located at the Hi-tech Horticulture unit, Saidapur farm, Main Agriculture Research Station (MARS), UAS, Dharwad during rabi 2015 to evaluate the effect of integrated nutrient management in cherry tomato under shade house condition. The experiment was laid out in randomized block design with 12 treatments in three replications. The variety used in this experiment was HAT-121 and duration of this crop was five month. The experimental results revealed that, treatment T11 (Azospirillum + PSB + 75 % RDF + FYM + Vermicompost) recorded higher plant height (249.48 cm), branches per plant (63.67) and leaves per plant (445.73) at harvest. This treatment also recorded higher fruit yield (47.81 t ha-1), number of flower clusters per plant (15.00), number of flowers per cluster (15.67), number of fruits per cluster (14.50), per cent fruit set (92.57), average fruit weight (8.50 g), fruit yield per plant (1.85 kg) and fruit yield per m2 (6.83 kg), TSS (8.1 0brix), ascorbic acid (24.0 mg per 100 g) and shelf life (22.1 days). The nutrient uptake of N (251.87 kg ha-1), P (43.63 kg ha-1), K (261.47 ha-1), the gross returns (` 9,56,158.93 ha-1), net returns (` 6,34,195.68 ha-1) and cost benefit ratio (1:3.0) was significantly higher in the same treatment as compared to other treatments. All these growth, yield, quality, nutrient uptake and economic parameters were lowest with application of Azospirillum + PSB + FYM and vermicompost equivalent to 100 % RDN (T12). The results of present investigation indicated that growing of cherry tomato with application of Azospirillum + PSB + 75 % RDF + FYM + Vermicompost was found profitable.
