9 Major achievements during Discipline: Plant Breeding Sl. No Target Achievement 1 2 MLT Grain sorghum Summer 2015 MLT forage sorghum Summer 2015 Three TNS cultures viz., TNS 638, TNS647 and TNS648 were tested. Among these TNS647 and TNS648 recorded grain yield of 2392 and 2250 kg/ha with increased yield of 7.19 and 0.8 increase ove local check Co 30. Besides they also recorded dry fodder yield of 10 and 11 t/ha. TNS 212 and TNFS1051 recorded highest green fodder yield of and kg/ ha respectively by recording and percent increase over check K11.

10 Major achievements during Discipline: Plant Breeding Sl. No Target Achievement 1 RRYT-Grain summer MLT-Grain Kharif 2015 Under RRYT fourteen entries were tested. The cross derivatives CO 26x IS recorded grain yield of 4150 kg/ha which was per cent higher than the local check Co 30. Another cross derivative APK 1 x M recorded grain yield of 4705 kg/ha with incresed yield of percent than the local check Co 30. It also high fodder yield 15 t/ha (30 % higher than the check. Eight cultures including check were tested. The culture TNS 648 recorded highest grain yield of 1982 kg/ha and fodder yield of kg/ha with increase of 31.2 per cent and 9.6 per cent respectively.

11 Major achievements during Discipline: Plant Breeding Sl. No 1 2 Target MLT-FS&SS Kharif 2015 RRYT Kharif 2015 Achievement Five entries including checks were tested. None of them excelled the check in green fodder yield potential Nine promising selections along with four checks were evaluated. Among this four derivatives viz., TNS 627 x TNS and TNS 630 x TNS ,TNS 629 x TNS , TNS 630 x CO ,TNS 630 x TNS recorded increased grain yield than all the checks. The highest yield was noted in TNS 629 x TNS (2618 kg/ha) followed by TNS 630 x TNS (2266 kg/ha). The results will be confirmed in UVT trial.

The 75 kg of seeds were distributed to 25 farmers in Coimbatore and remaining 15 kg (CSV27) were sent to KVK, Virinjipuram and distributed to the farmers. Another six obtained were also distributed to the farmers.

16 Major achievements during Discipline: Agronomy Sl. No Target Achievement Trial 4K. Prioritization of inputs in kharif grain sorghum Based on yield and economics of kharif sorghum, order of priority for achieving higher yield and economic returns was found to be weed control, fertilizer, plant protection, seed treatment, use of hybrid and thinning. Trial 5K. Intercropping of sweet sorghum fodder with forage Highest sweet sorghum green fodder equivalent yield, net returns and BC ratio with higherh LER were recorded d legumes under under intercropping of sweet sorghum different nutrient + cluster bean in 2:2 ratio which was management significantly higher than other intercropping systems.

17 Sl. No Target Achievement Trial 7K. Mechanization in grain sorghum (Exploratory study) Adoption of a spacing of 60 x 10 cm for grain sorghum helps to mechanize the operations of sowing, weeding and harvesting and save labour and time without reduction in yield and economic returns. University it ti trial on Effect Nitrogen application at higher h dose and of levels and sources of organic manure with higher nutrient nitrogen on yield and availability resulted in increased HCN HCN content of multicut content. Vermicompost with 125% N fodder sorghum (Co (FS) resulted in higher HCN content than 31) other manures and N doses.
