Afield study was conducted for four years (2003-2007) to investigate the effect of
tillage and integrated nutrient management practices on soil moisture
conservation and sorghum yield under different rainfall situations in a rainfed SAT
in India. Tillage treatments include conventional tillage, CT (1 ploughing + 2
harrowing + 2 hoeing + 1 hand weeding), reduced tillage, RT (2 harrowing + 1
hoeing + 1 hand weeding) and low tillage, LT (1 Harrowing + 1 hoeing + herbicide
application). Nutrient management treatments were 50% recommended rate of
nitrogen (RRN), 100% RRN and 150% RRN. Fifty percent Nwas applied through
farmyard manure and 50% N through urea. The differences of rainfall during a
year as well as cropping season had a marked effect on sorghum yield. Under
varying rainfall situations, CT conserved greater rainfall and improved soil
physical properties performed relatively better over RT or LT. We found that
sorghum response to INM varied differently under different rainfall situations in
all the 4 years of study. In drought year, 50% reduced N application served better
whereas in nearly drought year RRNsuits. In a good rainfall year, even 50% higher
RRNapplication produced greater sorghum yield significantly over lower rates.
