Abstract

A field experiment was conducled on a sandy soil to study the effect of tillage methods and irrigated crops on
physical properties of soil after wet-season puddled rice (Oryza sativa L.) during 1990 and 1991. The upland crops
grown in sequence with rice were blackgram (Phaseolus mungo L.), groundnut (Arachis hypogaea L.), castor (Ricinus
communius L.) and sunflower (Helianthus annuus L.), Land preparation with tractor-drawn mouldboard plough once
followed by rotovator tWice, and ploughing once with tractor-drawn mouldboard plough + disc harrowing recorded
lower bulk density (1.31,1.33 g/cc), higher porosity, infitration rate and hydraulic conductivity (7.3 cm/hr). Groundnut
recorded lower bulk density, higher hydraulic conductivity and infiltration rale compared with other crops.
