Sowing, harvesting time and delta of hill crops

Short answer

Paddy: sown Jun-Jul, harvested Oct-Nov, delta 120-140 cm. Maize: Mar-Apr/Jun, harvested Aug-Sep, delta 50-60 cm. Wheat: Nov-Dec, harvested Apr-May, delta 35-45 cm. Potato: Jan-Feb, harvested May-Jun, delta 45-50 cm. Millet: Jun-Jul, harvested Oct-Nov, delta 30-40 cm.

Write down sowing time, harvesting time and average delta of five principal crops of hills of Nepal.

The values below are typical for the mid-hills of Nepal (approximate; they vary with altitude, variety and soil, and textbook tables may differ slightly).

Notes

  • Paddy needs standing water and has the highest delta.
  • Wheat, a winter crop, is grown mostly with rainfall and a few irrigations.
  • Delta is the total depth of water a crop needs over its base period, including rainfall contribution if not subtracted.
  • Base periods are about 120-150 days for paddy, 100-120 days for maize and 120-140 days for wheat.
