Abstract
Two field experiments were conducted in 2000/2001 and 2001'2002 growing seasons at Sakha Agric. Res. Station to study the effect of three varieties of wheat (i.e. Sakha 69. Sakha 8 and Sids 1). water stress (irrigation at 50% and 75% depletion of the available soil moisture (OAM). land levelling practices (Il'lser & ;raditi.:.nai) and two methods of pld!ltio19 (driil and broadcasting) under :101'1 salt clayey affected soils on wheat production and some water relations. Split-split-splil plots design with four replicates was used. Varieties occupied the main plots, while irrigation treatments were placed the sub plots, land levelling practices arranged in sub-sub plots and the seedbed planting methods were the sub-sub-sub plots. ResuJls revealed that:
Sakha 69 variety with irrigation at 50% DAM, precision levelling (laser) and drill planting method were' the best combination which obtained significantly exceeded planl height (3.6%), panicle length (14.49%). 100 grain weight (9.91). grain and straw yields (12.36% and 7.09%), respectively.
Irrigation at 50% depletion of the available soil moisture (DAM). traditional land levelling and broadcasting method of planting under Sakha 69 variety received the highest amount of irrigation water requirements (2391.40 and 2241.73 mJ/fed.) and consumed more water (1783.11 and 1664.30 m3/fed.) more than the other treatments in the first and second seasons. respectively.
The highest values of field water use efficiency (1.38 and 1.54 kg/m3) and crop water use efficiency (1.66 and 1.85 kglm~ were recorded when the crop subjected to 75% DAM. laser levelling. drill method of planting under Sakha 69 variety in the first and second seasons, respectively.
Irrigation at 75% DAM, laser land levelling and drill method of planting recorded the highest values of water application efficiency (84.31%) under Sids 1 variety compared with other treatments.
