3. TECHNOLOGIES EVOLVED
  1. a) CASHEW:
  1. Control of Tea mosquito Bug: Spraying of monocrotophos at 0.5% at flushing, carbarge at 0.1% at flowering and cabaryl at 0.1 % at fruiting stage was recommended for the control of tea mosquito bug in maidan parts of Karnataka.
  1. The CSRB incidence is moderate and causes mortality of trees. The curative treatments include mechanical removal of grubs and swabbing with carbaryl 50g + copper oxychloride 50g in one liter.
  1. Fertilizers for cashew: An annual nutrient dose of 500g of nitrogen, 250g of phosphorous and 250 g of Potassium per tree has been recommended for cashew in the maidan parts of Karnataka.
  1. Grafting season for cashew: For obtaining maximum success in cashew propagation, softwood grafting during the months of July- October has been recommend for maidan parts.
  5.Varieties recommended: For maidan parts of Karnataka, Ullal-1, Ullal-3, Ullal-4, NRCC-2, Vengurla-3, Vengurla-4 and Dhana varieties have been recommended besides Chintamani-1 and Chintamani-2 released from this centre.
  1. b) GROUNDNUT:
  Technologies included in the package of practices:
  
  Use of Bio-fertilizers: Use of Rhizobium along with phosphorous solubilising micro-organism (Aspergillus awamori) in combination with farmers practice of application of 50 kg DAP/ha has been found to be effective as the recommended dose of fertilizers (25:50:25 kg NPK/ha) without reduction in yield. This practice of integrating bio-fertilizers with farmers practice has been recommended for application in the farmers field.
  
  Use of micro-nutrients: Application of micro nutrient Viz. FeSo4, and Borax at 10.5 and 1.0 kg/ha, respectively enhanced the pod and kernel yield (1760, 1313 kg/ha respectively), netreturns (Rs.16, 120/ha) and BC ratio of 2.96. This practice is found to increase the seed quality parameters Viz, shelling % SMK and oil %.
  
  Use of Gypsum: Band placement of gypsum at 500 kg/ha followed by earthing up at about 30-35 days after sowing (after start of flowering) has been recommended to the farmers to enhance kernel development and achieve higher yield and shelling out-turn. This technology is being adopted by the majority of the farmers (75-80%).
  
  Integrated weed management in groundnut: Integrated weed management involving application of pre-emergent weedicide Pendimethalin at 1.0 kg a.i/ha followed by one hand weeding at 30 DAS and two interculture operations at 30 and 45 DAS has been found to be efficient in weed control and also cost effective.
  
  Intercropping in groundnut: Inter-cropping of chilli with groundnut at 2:8 ratio has been found to be remunerative with a cost benefit ratio of 1:2.9 than the existing pigeon pea and groundnut combination. This practice has been recommended for adoption in the farmers fields.
  
  Organic farming in groundnut: Application of 15 t/ha along with 100% RDF recorded higher yield and monitory returns compared to 150% RDF.
  
  Plant Growth Promoting Rhizobacteria (PGPR) use in groundnut: Seed treatment with combined application of PGPR 1+2+4 gave maximum pod yield ( 1667 kg/ha) and net returns( Rs.26,617/ha) (based on three years mean data).
  
  Use of Bio fertilizer Consortium in Groundnut: Three years of mean data on bio fertilizer consortium ie., Enriched Compost + Rhizobia + T.harzianum as seed innoculation before sowing along with 50% NP+100% K recorded significantly higher pod yield (37% increase over control), kernel yield (1011 kg/ha) , shelling percent (73.9%) & higher No. of nodules (86.0) compared to control( 61.4).
  1. c) AGRO-FORESTRY
  Alley cropping of field crops with perennial leguminous species:
  
  In water shed areas, growing of perennial legume species such as Glyricidia and Subabul for green leaf bio-mass across the slope at a row distance of 8m and intra row distance of 1.5m provides for profitable and sustainable cultivation. If field crops such as ragi and groundnut are grown between the hedge rows, after two years of planting, the perennial plants have to be pruned and maintained one meter height 3-4 loppings of green leaf can be obtained per year which can be used as green fodder or composted for recycling to the field crops. This alley cropping system will help in improving the soil fertility and productivity on sustainable basis under dry farming situation over years.
  
  TRANSFER OF TECHNOLOGY
  
  CASHEW
  
  Establishment of model clonal orchards: A total of 40 model clonal orchards of cashew (0.4 ha each) were established in the farmers fields from 1994-2002 for demonstrating the improved production technologies to the farmers of maidan parts of Karnataka.
  
  GROUNDNUT
  
  Seventy -five frontline demonstrations conducted on the farmers fields (0.4 ha each) for the over years indicated that overall increase of 37.5% by following improved technologies (Variety K-134, ICGV-91114 & KCG-2 ) at a cost benefit ratio of 2.80 over farmers practice. Inter cropping of groundnut with pigeon pea was reported to be highly remunerative and productive.
  
  Nursery Activities: Elite grafts of Mango, Cashew, Tamarind & Jamoon grafts were produced and supplied to the needy farmers.
  
  ORGANIC FARMING RESEARCH:
  
  Research on organic farming activities was initiated from 2006-07 under the funding agency of National Centre on Organic Farming, Government of India.
  
  * Application of FYM 10 t/ha as basal dose+ Bio-digester liquid applied in two split doses as
  
  top dress to Ragi, Groundnut and Redgram was found to be higher yield (20%) than RDF.
  
  * For the last 4 years trials were conducted on Ragi, Red gram, Groundnut and Mango and it was found that from 2^nd year onwards the yield of almost all organic crops were on far with the crops grown under in organic method. The cost benefit ratio was higher under organic production.
  
  * Use of Bio-digester liquid to Ragi, Red gram, Groundnut and Mango crops in 2 split doses at 30 and 40 days after sowing. The yield of organic crops recorded higher (20%) then inorganic crops. Further, the cost involved for top dressing is to be reduced.
  
  * On farm demonstrations were conducted on production of different crops (Ragi, Red gram and Mango)
  
  Preparation of NSK, Jeevamrutha, Panchagavya and Bio-digester liquid was demonstrated to farmers.
  
  * Several training programmes have been arranged on farm and off farm on organic farming practices for production of different crops.
  
  INCOME GENERATING ACTIVITIES:
  - Production of Mango, Cashew, Tamarind and Jamoon grafts.
  - Production of different kinds of Ragi and Redgram seeds.
  - Dairy maintenance and sheep rearing.
  TRAINING PROGRAMMES:
  
  The scientists of the station are involved in the following training programmes:
  - As master trainers/resource scientists in the bi-monthly technical workshops to train the extension personnel of KSDA under NAEP (T&V) programme.
  - Organizing Krishi melas/field days during the cropping season for transfer of new technology to the farmers and extension agencies.
  - Participating as resource persons in various training programmes like NPDP, OPP, ICDP, water shed, intensive maize and sugarcane production technologies organized by KSDA, GOK.
  - Regular field advisory visits were made to the farmers field to get feedback and to solve field problems.
  - Popularization of new technologies through TV/Radio/Newspaper/literature.
