1304- System of Wheat Intensification in Kailali Nepal (SWI)

  1. 1. SYSTEM OF WHEAT INTENSIFICATION (SWI): A NEW TECHNOLOGY FOR WHEATINTENSIFICATION PRACTICED IN KAILALI, NEPAL Ram B Khadka Programme Coordinator European Union Food Facility Project, FAYA- Nepal, Dhangadhi, Kailali
  2. 2. What is SWI ?New concept and practice of wheat cultivation manipulating the soil environment favorably for better root and shoot growth using principles of SRI Wide spacing of plants for better light and air utilization Increases use of compost and organic matter Quality seed to be selected and treated using appropriate biotic and biotic agents Better soil aeration by use of mechanical weeder
  3. 3. What have done at Kailali?• Four farmers controlled field trials were designed and established at Ramsikharjhala, Lalbojhi, and Fulbari• Each trial had two treatments: 300m2 for farmers practices and 300 m2 for SWI• Variety used: Gautam and Bhirkuti• Broadcasting of seed with recommended dose of fertilizer i farmers’ practice• Germinated seeds planted in-line at a distance of 20 cm pla to- plant and 20 cm line-to-line by dibbling methods• Gap-filling was done by transplanting individual wheat seedlings at 10 DAS• Fertilizer dose 100:50:50 Kg NPK/ha and 10 MT FYM per ha• At 20, 40 and 60 DAS, irrigation were done and each 5 days after irrigation weedings were done by SWI weeder machin•
  4. 4. Obser-vations• Tiller number• Plant height• Spike number per hill• Number of grains per spike• Total grain weight• Number of spike per m2Data were taken separately for conventional practices, for SWI direct sowing, and for SWI seedling transplanting by randomly selecting 10 plants from each type

  6. 6. What was lacking in SWI practices at Kailali?• Seeds were selected and treated by hot water only; but better results can be expected with treatment using a mixture of jaggery, vermi- compost, cow urine, and biotic agents like Aspergillium in usual practice of SWI• Dibbling of seed was done manually so there were differences in seed depth (3-4 cm is most appropriate) hampering germination percentage; use of a SWI drill machine can help uniform seed depth
  7. 7. Discussion• Wheat plants in SWI (leaf width, leaf colour, root length, and root distribution ) were seen to be quite different; in SWI, leaves were more green and wide, roots are deep and well distributed• The transplanted seedlings did not have as good performance in tillering as did direct sowing• SWI wheat remains greener than conventional, even when ready to harvest ; seen as more tolerant of hot stress; later senescence appeared in SWI
  8. 8. Different between SWI and conventional practices observed at KailaliSN Parameters SWI Conventional1 Seed requirement 25-30 kg/ha 100-120 Kg/ha2 Seed treatment Should be done by with Not necessary biotic and biotic agents3 Methods of sowing Dibbling in line Broadcasting4 Spacing 20 x20 cm No proper spacing5 Weeding 2-3 weedings by using Not done cono-weeder6 Length of panicle (cm) 18 127 No of grains per panicle 60-75 40-508 No. of panicles per hill 53-40 2-59 TGW (gm) 70-75 45-5010 Stem, roots & leaves Thick stem, long root and Thin stem, short and surface root
