Abstract
AbstractFour preplanting tillage methods including turn plowing, chiseling, double disking — all followed by a light cultivation — and no tillage were tried on pearl millet (Pennisetum typhoides, S. and H.) under dry land conditions. Turn plowing resulted in the highest infiltration rate and lowest bulk density values. In consequence, it showed maximum profile soil moisture throughout the growing period of the crop. Variation in soil moisture was more marked in the 60‐ to 90‐cm depth than the upper layers. Grain yield from turn plow plots was about 29% higher than that from the no tillage. Root growth was comparatively poor, but weed yield was more than double on the nontilled plots than on those that were turn plowed. Most of the plant and soil observations showed little difference between turn plowing and chiseling, while double disking was close to no tillage.
