Abstract

A field experiment was conducted on sandy-loam soil at New Delhi during 1999-2000 to 2001-2002, to study the effect of bed planting system in increasing water-use effciency of wheat(Triticum aestivum L. emiend.Fiori & Paol.) In comparison to conventional system, significantly lower bulk density, lower penetration resistance of upper 0-20 cm soil and high infiltration rate on bed created better soil phsical environment, which resulted in 30, 20 and 5% respectively,under bed planted system compared to conventional sytem. Crop water stress index measured at different crop growth stages also showed that crop experienced same level of stress in bed and conventional system, although lesser water was applied in the bed system. Manual weeding for weed control was found more effective in bed planting treatment than in conventional, as evident from the significantly lower weed population/m² in the former. Average of 3-year data showed that total water use by the crop was reduced nearly by5 cm, whereas yield and water-use effciency increasedd by 0.22 tonne/ ha and 0.03 tonne/ha, respectively, under treatment with 3 rows of wheat per bed compared to conventional planting.
