A field experiment was conducted during the winter (rabo seasons of 1996 97 to 1998 99 at Bilaspur, Chhattisgarh, to study the yield, water use and nutrient uptake of wheat (Trticum aestivum L. emend. Fiori Paol.) as affected by varieties, irrigation and nitrogen level under late sown conditions. Among the varieties, DL 788 2 and DL 803 3 were superior to GW 190 and GW 173 . Irrigation applied at 1.2 IW : CPE ratio gave significantb higher grain yield than 0.6 and 0.9 ratios. Application of 120 kg Nlha gave higher yield and yield attributes than 80 kg Nlha. Total nutrient uptake was positively influenced by irrigation and N levels. Total water use was lowest (29.60 cm), while water use efficiency was highest with 0.6 IW : CPE.The WUE decreased with the increase in fre quency of irrigation. The moisture depletion from upper soil layers (0 60 cm) was higher than lower layers (60 90 cm). However, total profile moisture contribution was highest with limited water supply (0.6 IW : CPE) and de creased with the increase in number of irrigation. Canopy temperature was comparatively low than ambient tem perature under higher moisture (1.2 or 0.911.2 IW : CPE) than lower moisture regime (0.6 IW : CPE).References
