water and also groundwater used for soybean demonstration plots have resulted in significant
increase in yield as compared to rainfed condition or without irrigation at the Warkhed-
Kajaleshwar watershed. It was observed that the average yield of soybean with one protective
irrigation was increased in the range of 16.00 % to 33.00 % over without irrigation. During
rabi season for chickpea the stored rainwater was used for protective irrigation. It was observed
that the average yield of chickpea with one protective irrigation was increased in the range of
16.92 % to 29.52 % over without irrigation. Similarly, the average yield with two protective
irrigations was increased in the range of 30.18 % to 52.00 % over without irrigation.
Conclusion
It can be inferred that due to storage of water for longer time in the drainage line (Nallas,
CNBs), the well recharge took place resulting into increase of ground water table. Thus,
sufficient water will be available for providing protective irrigations to different crops. The
farmers were able to raise different crops thereby having more income generation compared to
earlier situation. Crop diversification and sustainability in agriculture occurred. Based on these
results it can be recommended to undertake the deepening and widening of existing drainage
line network along with construction or repairing of the permanent structures and reuse of
harvested water through micro-irrigation in the entire Vidarbha region of Maharashtra for
sustainable crop production and water resources development.

Leafy vegetables like lettuce demands more water and nutrients for better production, which
sometimes leads to unbalanced and indiscriminate application of inputs. A field experiment
was designed to find out the performance of lettuce under irrigation scheduling based on
IW/CPE ratio combined with application of nitrogen through different sources.
