• Spraying with Ca, S and Fe @ 25, 25 and 10kg /ha, respectively increased the yield and improved the quality of chilli.
• For the management of chilli pests, the following integrated pest management technology has been developed and recommended.
  • Planting chilli with marigold in 18:1 ratio
  • Application of 50% recommended dose of NPK
  • Application of Vermicompost @ 25q/ha + neem cake @ 2.5q/ha at the time of planting.
