Forming Ridges and Furrows/beds

i. Form ridges and furrows (using 3 ridges) 6 m long and 45 cm apart. If pulses are intercropped, form ridges and furrows 6 m long and 30 cm apart. ii. If ridge planting is not followed, form beds of the size 10 m2 or 30 m2 depending upon water availability. iii. Form irrigation channels. iv. To conserve soil moisture under rainfed condition, sow the seeds in flat and form furrows between crop rows during intercultivation on third week after sowing.
