India is an agrarian country, where rainfed agriculture accounts for two-thirds of the total
cropped area (66 %) and contributes 40 per cent to the national food basket. The mean annual
rainfall in rainfed region ranging from 400 mm to 1000 mm, which is uncertain, erratic and
unevenly distributed. Among 400 M ha-m of rainfall received, 150 M ha-m flows as surface
runoff, subsurface runoff and will not available to any type of production in India. To mitigate
the runoff caused by uneven, erratic and heavy rains, in-situ and ex-situ water harvesting
techniques can be used efficiently. During the rainy season when water is not required for
irrigation, the excess water can be stored in a ancillary reservoir or farm ponds and used
effectively during crucial periods of crop growth (Ramachandrappa et al., 2017). The in-situ
water harvesting can be attained through selection of proper cropping systems. In this regard,
the predominant crops and cropping systems of Eastern dry zone of Karnataka were selected
to standardize the efficient cropping system to reduce the runoff, soil loss and nutrients loss.
Along with cropping systems the harvested water in farm pond is used as protective irrigation
during dry spells to the know effect on yield and yield parameters of different cropping systems.
