- Development of medium and long duration hybrids suitable for rainfed and irrigated ecologies of Kharif and Rabi season
- Development of early and medium duration single cross hybrids for the rainfed ecosystem in southern Karnataka.
- Disease screening of early, medium and long duration hybrids and specialty corn hybrids against Turcicum leaf blight, Common rust and Charcoal stalk rot diseases.
- Survey and surveillance, Epidemiology and management of Turcicum leaf blight, Common rust and Charcoal stalk rot diseases.
- Agronomic investigations of Kharif and Rabi Maize for rainfed and irrigated ecologies.
Farm area: 22 Acres
- In 1955, a three way hybrid S-23 (I-5 × L-5) was developed and released by this centre which recorded 30 per cent higher yield than Arabhavi local with two per cent higher protein.
- During 1957, the center was upgraded to AICRP (Maize) centre. Further, the centre contributed for the release of Deccan, Ganga-1, Ganga-101 hybrids and Ranjit composite by the project in 1961.
- From 1968 to 1987, the centre collaborated in release of maize hybrids like Deccan-101(1975), Deccan-103 (1982) and Deccan-105 which were recommended for Karnataka.
- An early maize composite G-25 (Renuka) which matures in 85 to 90 days and was found suitable for growing with 170 CO-2 cotton, which became popular in mixed cropping system of this region was released in 1984.
- During 1989, another full season composite G-57 (Prabha) was developed which was on par with the yield of Deccan-103 with tolerance to borer infestation, Turcicum leaf blight, downy mildew, Erwinia stalk rot and late wilt.
- The double top cross hybrid DMH-1 with 15% per cent higher yield compared to Deccan-103 and Prabha was developed and released during 1996.
- The first ever single cross hybrid DMH-2 (CI-4 × KDMI-10) was developed and released for Karnataka during 2002.
- During 2009, a modified single cross hybrid EH- 434042 (Arjun) with multiple disease tolerance was developed and released for Northern parts of Karnataka.
- In the year 2012, a single cross hybrid GH-0727 (Shrushti) has been released for Karnataka state.
- Intercropping of maize in cotton or newly planted sugarcane with early maturing maize genotypes is a remunerative cropping systems for the small and marginal farmers.
- Intercropping of two rows of soybean in between 90 cm rows of maize is found profitable and farmer could get additional profit over sole maize.
- The planting geometry of 60×20 cm recorded higher grain yield than either 75×20 cm or 60×30 cm. Maize responded up to 150% of RDF without the application of FYM.
- Application of 150:65:65 kg N:P2O5:K2O per ha with nitrogen in 5 splits @ 10% at basal, 30% each at 4 and 8 leaf stage, 20% at tassel emergence / flowering stage and remaining 10% N at early grain filling stage recorded higher grain yield than recommended practice of N application in 3 splits (33% each at basal, 30 and 45 DAS).
- Sequential application of pendemethalin (1000 mlha-1) as pre-emergence followed by Atrazine (750 g a.i. /ha) + 2,4-D Amine 0.4 kg a.i./ha at 25 DAS as Post emergent recorded significantly lower weed counts and higher grain yield.
- For management of TLB spraying of Mancozeb @ of 2.5 grams/lit. of water after initiation of the disease should be done at knee-high stage. Second and third spray to be done at intervals of 10 days, if necessary.
- Spraying of propiconozole 25% EC (Tilt) @ 1 ml/lit. of water at 30 and 45 days after sowing proved most effective in controlling rust.
- Application of Pseudomonas fluorescens @ 0.5% as seed treatment with bioagent-fortified FYM (1:50) and spray @ 0.5% found effective in suppressing the PFSR.
- Foliar application of Tebuconazole 250EC @ 0.1% showed combined resistance to TLB and Common Rust diseases and resulted in 38.16% increase in yield over untreated control.
- Single cross hybrid GPMH-1101 has been identified for release for Zone 3 (Northern dry zone) of Karnataka state. Notification awaited.
- Two genetic stocks, DHKN 509 and DHKN 563 with high kernel rows have been submitted for registration with PPV-FRA
- Single cross hybrid GH-0727 (Shrusti) has been registered with PPV-FRA.
- Foliar Application of combi product fungicides namely, Trifloxystrobin 25% + Tebuconazole 50% (Nativo) @ 0.1%, Azoxystrobin 18.23% + Difenoconazole 11.4% (Amistar Top) @ 0.1% found significantly superior with respect to TLB and common rust diseases control and resulted in 35 to 41% increase in grain yield over unprotected check.
- Pseudomonas fluorescens @ 0.5% as seed treatment, biogent-fortified FYM (1:50) and spray @ 0.5% found effective in suppressing the PFSR which recorded 47.66% disease control efficacy and resulted in 21.32% increase in grain yield over untreated check.
- IDM module comprised of seed treatment with Trichoderma harzianum @ 10g/kg seed + Thiram 75WP @ 2g/kg seed, foliar application of Nimbicidine @ 5ml/litre @ 35 DAS, followed by Azoxystrobin 18.2% + Difenoconazole 11.4% (Amistar Top) @ 1ml/litre of water at 35-40 days after sowing found ideal IDM strategy for TLB management which resulted in 27.12% increase in grain yield over unprotected check.
- Two CIMMYT lines viz., VL 176109 and VL 176270 registered resistant reaction to TLB.
- Application of Atrazine @ 1.5 kg/ha pre-emegence followed by Tembotrione (Laudis) 120 g a.i./ha PoE at 25 DAS recorded significantly lesser weeds population and higher maize grain yield.
- Ecological intensification treatment resulted significantly higher grain yield and net returns compared to farmers’ practice.
