Description The current climate change scenario calls for efficient management of soil available water which requires adequate knowledge of soil hydraulic properties. This study was, therefore, carried out to evaluate the effect of tillage and mulching on soil hydraulic properties in a rice- wheat system. The study was a splitsplit plot experiment in randomized complete block design with three replications. The main plot was tillage under wheat cropping (conventional tillage (CTW) and zero tillage (ZTW)), the sub-plot involved tillage under rice cropping (CTR, ZTR and puddling (PTR)) while the sub-sub plot included rice straw mulching (0 and 6 t ha-1). Soil volumetric water content (θv) was determined using time domain reflectometer. Tensiometers were installed to guide in field irrigation.Water evaporated from the soil and soil moisture enrichment (SME) were estimated using data obtained from the installed minilysimeters. It was observed that ZTW plots had higher θv than CTW plots similar to higher θv in mulched than unmulched plots. Tensiometric regulation of irrigation led to about 60% water saving without reduction in grain yield. Poor wheat tillering possibly increased soil water evaporation in ZTW than CTW plots while more water availability under CTR could be linked with more evaporation recorded in CTR than ZTR plots. Covering the soil surface with mulch led to about 154% reduction in soil evaporation compared with unmulched plots. Soil moisture enrichment by ZT was about 35% to 312% higher compared with CT while mulching raised SME by 205% compared with the unmulched soil. Insignificantly lower grain yield was obtained in ZTW plots than CTW while significantly (P<0.05) lower grain yield was recorded in CTR plots than ZTR. Therefore, appropriate tillage system coupled with soil surface management and monitoring of soil hydraulic properties during wheat growth are important to improve irrigation water efficiency and land productivity.
