Bengalgram (Cicer arietinum L.) cultivar ICCC–37 was grown as a sole crop with a spacing of 30 × 10 cm and with the recommended rate of fertilizer application during winter season of 1998–99 at Soil Conservation Research Farm, Bellary, Karnataka State, India in the Vertisols. A plot size of 12 m2 was found to be optimum in bengalgram crop sown during the postrainy (rabi) season for field experimentation under dryland situations. Among other factors, variability due to any given plot size was found to depend on the crop geometry. Rectangular plots are more efficient in minimizing the error variability compared to square plots.
