Methods of water harvesting

a) Water harvesting in small tank: The 4m x 3mx 2m sized tanks are getting popularity for water harvesting now a days. The collected water can be used for irrigation purpose.

b) Inter row water harvesting: It provides ridge and furrow system. It is done in case of winter and spring crops. Crops are grown in the furrows in winter and spring and ridges in rainy season.

c) Broad raised bed and furrow: On the bed mixed cropping lime maize + arhar or sorghum + arhar can be grown. In the furrows rain water is collected which is utilized by the crops. If there is excess water from furrows could be led to the tanks.

d) Inter plot water harvesting: Rain water falling in the micro-catchments is harvested in to the cultivated strips. Micro catchment is sloping towards cultivated strips. Example: 40 cm rain becomes 70 cm rain to cropped area (addition of 30 cm). If the flat is there, then earthwork is needed and if undulated land and then try to adjust the slope lime this. This can be done in light soil because of high infiltration.
