A field experiment was conducted during 2002-03 to 2004-2005 in red soils to explore the possibilities
of rain water harvesting through a farm pond for providing supplemental irrigation to soybean, toria
and Indian mustard for increasing growth, yield and water use efficiency. Harvested rainwater was
available for supplemental irrigation in farm pond from middle of August to end of October during all
the years. Growth and yield attributes of soybean (plant height, number of primary and secondary
branches/plant, pods/plant, pod length, number of seed/pod, seed weight/plant and 1000-seed weight),
toria and Indian mustard (plant height, number of primary and secondary branches/plant, number of
siliqua/plant, siliqua length, number of seed/ siliquae, seed weight/plant and 1000-seed weight)
increased with supplemental irrigation which in turn increased the yield of the crops during all the
years. Yield of soybean and toria increased by 31 and 138% with supplemental irrigation given at pod
filling and 30 days after sowing, respectively over no irrigation. Yield of Indian mustard increased by
91% with one pre-sowing irrigation, and by 343% with pre-sowing + irrigation at branching stage, over
rainfed crop. Water use efficiency of all the crops increased with supplemental irrigation. The water
use efficiency of soybean and toria increased by 15 and 37% with supplemental irrigation at pod filling
and at 30 days after sowing, respectively, over no irrigation. The water use efficiency of Indian mustard
also increased by 25 and 45% with pre-sowing and pre-sowing + irrigation at branching stage,
respectively, over no irrigation. The results suggested that the productivity of large rainfed areas in the
country could considerably be increased even in red soils through rainwater harvesting and providing
supplemental irrigation at critical stages of crop growth from a farm pond to some of the selective
crops such as soybean during kharif season further available water can also be utilized for providing
pre-sowing/supplemental irrigation to post monsoon/rabi season crops such as toria or Indian mustard
for increasing the growth, yield and water use efficiency in semi-arid conditions.
