Technologies

Plant Breeding and Genetics

·         A greengram VRM (Gg) 1, pure line selection   was released as a variety in 2000 and it recorded the highest yield of 1020.4 kg/ha.

·         Sorghum germplasm lines viz., CSV 15, SPV88, TNS 297, SSVT-SR-350-12-ISV 0413, 192-15-3, 2029-42 and 2026-1-1-1 were selected as high alcohol yielding sweet sorghum lines.

·        Of the 105 sorghum cultures evaluated, Poigai local (Thalaivirichan type) was found to be most promising.

·        In greengram breeder seed, 3887 kg in K.851 and 256 kg in VRM(Gg)1, besides 401 kg of TFL in VRM (Gg)1 was produced and supplied to State Department of Agriculture and farmers.

·        VMS 98001 a sweet sorghum   culture was selected for dual purpose i.e., for alcohol and grain production.

 

Soil Science and Agricultural Chemistry

·         Maize varieties Co1 and African tall, Co13 ragi and BN2 grass were identified as suitable crops for tannery polluted areas.

·         Application of composted coconut coirpith @ 10 tonnes /ha in the tannery polluted area was found to be the best soil amendment.

·        Application of tannery effluent to soil resulted in reduction of hydraulic conductivity from 7.48 to 3.35 cm/hour, soil porosity from 41.2. to 31.6% and increased the bulk density from 1.4. to 1.5 g/cc.

·        The ground water samples of Pernampet and Ambur belts were found to be contaminated with tannery effluents.

·        Electrical conductivity of contaminated ground water samples indicated the toxic EC range of 9 to 10.

·        Phytotoxic elements like Sodium and Chloride exceeded the critical limits and recorded 2935 mg/1 and 223 mg/1 respectively.

 

Crop Physiology

·         In rainfed pulses, seed pelleting with ZnSO4 (Black gram) or MnSO4 (greengram) at 100 ppm increased the yield by 18.6% and 15.3% respectively.

·        DAP (2%) foliar spray at two stages (peak flowering, pod development) boosted the yields of irrigated greengram (14.7%) and black gram (17.6%).

·         Tannery sludge upto 80 t/ha had no phytotoxic effect on paddy, tomato, brinjal, cucumber, groundnut, cowpea, bhendi and lucerne in pot culture experiment.

 

Agricultural Microbiology

·         Water hyacinth was found to absorb the toxic element chromium present in tannery effluent.

·         The bacteria Pseudomonas sp. reduced the toxicity of the tannery effluent.

 

Horticulture

·        Spraying of 2,4-D (25ppm) on the Poovan bunch within 15 days after the opening of the last hand produced better grade bunches

·         Urea blended with neem cake had increased the productivity and suppressed the nematode level in “Rasthali” banana.

·         Poovan banana (AAB) was tolerant to drought condition whereas Robusta (AAA) was susceptible.

·         The first and second ratoon crops of Poovan banana require the same fertilizer dose of 110:35:330 g NPK / Plant as that of main crop

·         The dwarf Cavendish banana grown at a spacing of 1.5.m x 1.5m  (4444 plants /ha)   accommodates 1,358 more plants per hectare instead of prevailing spacing 1.8 m x 1.8m (3,086 plants /ha)

·         Application of Pendimethalin as pre-emergence herbicide at one kg/ha followed by Imazethapyr as post – emergence heribicide (10 DAP) at one kg/ha controlled weeds in tomato.

·         In banana, application of glyphosate at one kg/ha each at 30 DAP and 30 days after first earthing up on 3rd month recorded higher bunch weight.

·         Azospirillum @ 18 g / plant applied in three splits (basal, 3rd and 5th months after planting) resulted in higher yield with the cost benefit ratio of 1:3.17 in banana.

·         VMB 7 was identified as a promising “Mullukathiri” local brinjal.

 

Agricultural Entomology

·        Spraying of neem seed kernel extract (NSKE) 5% at 10 days interval from flower initiation controlled the fruit borer in brinjal

·        Spraying of NSKE 5% thrice at 10 days interval from flower initiation was effective against the gram pod borer, Helicoverpa armigera on redgram.

·        Sorghum cultures viz., EC 0024, MS 1142 and TNSH 9407 were resistant to sorghum shootfly.

·        Spraying of NSKE 5% on 10th and 20th day after sowing was effective in controlling sorghum shootfly.

·         Spraying of NSKE 5% on 75 and 90 days after sowing controlled the sesame pod bug, Elasmolomus sordidus.

·         Spraying of Acephate @ 600 g/ha or Triazophos @ 500 ml/ha on 75 and 90 days after sowing was effective against sesame pod bug.

 

Plant Pathology

·        Incorporation of Trichoderma viride and T. harzianum and application of neem cake in nursery reduce the damping off disease of tomato

·         Spraying of Mancozeb 0.2% thrice at triweekly interval controlled leaf spot diseases of tomato.

·        Spraying of Carbendazim 0.2% at triweekly interval reduced the black spot disease of rose.

·         Capsule application of Carbendazim @ 80 mg/corm controlled the panama disease of banana.

·         Making field visits and suggesting suitable remedial measures.

·         Rendering farm advisory services.

·         Conducting off /on campus meeting.

·         Imparting trainings on the latest technologies.

·         Distribution of extension literatures.

·         Dissemination of technologies through AIR and TV.
