  • Among   nutrient   management   methods, Leaf Color Chart (LCC) based N application resulted in highest yield across all the locations closely followed     by   150% recommended fertilizer dose.
  • The    evaluation    of    crop    establishment methods   along   with   different   nutrient combinations over ten locations clearly indicated superiority of System of Rice Intensification (SRI)  (4.7  t/ha)  over  direct seeded with SRI principles (4.26 t/ha).
  • Site Specific Nutrient Management (SSNM) results based on Nutrient Expert revealed that, it was effective in increasing the yield in all the locations. Over all mean yield was 5.49 t/ha under same treatment followed by SSNM based on LCC (5.32 t/ha).
  • Mechanized System of Rice Intensification (SMSRI) showed better performance with overall  mean  grain  yield  in  all  locations (5.49 t/ha) followed by manual hand transplanting in lines and crop management for puddled transplanted rice (SRI) (5.26 t/ ha).
  • The economical and efficient dose of new combination herbicide i.e., Penoxsulam + Butachlor @717.5 g a.i./ha was effective for control of weeds in transplanted rice.
  • The high yielding varieties, Mandyavijaya and       Dhanrasi    exhibited    better    weed suppressing      ability.   Hybrids   and   long duration high yielding varieties were found to have better weed suppressing ability over short duration varieties.
  • RDF  +  split  application  of  N  resulted  in highest kharif rice yield (5.0 t/ha) followed by Azotobactor + PSB + brown manuring with Dhaincha + residue mulch @ 2 t/ha +75% RDF. Location specific recommended practices  of  NPK  +  ZnSO4  (100:50:50:20) at Mandya location recorded highest yield (7.91 t/ha) than rest of the treatments.
