Soil erosion, low nitrogen availability and soil moisture stress during winter
season are among the major limitations to high crop production and sustainable
land management in a rainfed Semi-Arid Tropics (SAT) in India. We conducted
three years field study (2000-01 to 2002-03) on a Vertisol to study the impact of
land configuration and nitrogen management on winter sorghum productivity
under different rainfall situations. Greater quantity soil moisture availability in the
profile with rainwater conservation techniques (RCT), compartmental
bunding (CB) and ridges and furrows (RF) from sowing to harvest produced 17 to
22% higher sorghum grain yields over flat bed (FB) sowing. Sorghum grain yields
and water use efficiency (WUE) were higher during mild moisture stress year
compared to normal rainfall year with rainwater conservation techniques. In the
sub plot, application of 20 kg N ha-1 produced 19% higher grain yield during a
drought year. Further increase in N application to 40 kg ha produced 22% higher
yield during normal rainfall year. Mean sorghum yield during study period was
19% higher with 40 kg ha compared to 0 kg N ha-1 . The CB and RF with
application of 40 kg N ha-1 produced greater winter sorghum yields in Vertisols of
1south India under rainfed situations
