Water is the main limiting factor for agricultural expansion in arid and semi-arid regions as well as Egypt. So two field experiments were carried out during 2015 and 2016 summer season at the experimental farm of Sakha Agricultural Research Station, Egypt to enhance water productivity of rice using irrigation intervals, transplanting methods and weed control treatments. Strip split-plot design with three replicates was used in infested weedy soils. Irrigation intervals were in the horizontal plots, it was irrigate every three days as a farmer practices (I₁), every six days (I₂) and every nine days (I₃). Transplanting methods were located in vertical plots contained; transplanting in flat soil as a traditional method (M₁) and transplanting in bottom of raised-bed (M₂). While weed control treatments were assigned in sub-plots, it was penoxsulam (Granite) 24% SC (W₁), penoxsulam + orthosulfamuron 50% WG (Kelion) (W₂), thiobencarb50% EC (Citron) fb penoxsulam (W₃), weedy check (W₄) and hand weeding twice (W₅). Results showed that treatment of I₁ was the best in weed management, rice dry weight, number of panicles/m², number of filled grain/panicle, 1000-grain weight and grain yield. Irrigation treatments of I₂ and I₃ saved about 20.7 % and 29.9 %  of irrigation water compared to I₁, while the highest productivity of irrigation water (PIW) were recorded by treatment of I₂ compared to I₁ and I₃. The lowest fresh and dry weights of total weeds and the highest values of rice dry weight, number of panicles/m², number of filled grains/panicle, 1000-grain weight were recorded by M₁ as compared to M₂, in addition rice grain yield of M₁ was increased by 7.1 % compared to M₂ as mean of the two growing seasons. Transplanting method of M₂ saved about 21.2 % of irrigation water and increased PIW by 18.4 % compared to M₁. The best weed management beside the highest values of number of panicles/m², number of filled grain/panicle, 1000-grain and grain yield of rice were obtained by W₃ compared to rest weed control treatments and it take the descending order W₃ > W₅ = W₂ > W₁ > W₄ in the two seasons of study. The interaction of I_{2 X} M_{1 X} W₃ wassuperior treatment for rice grain yield. But, under shortage of water, increasing irrigation water productivity of rice could be achieved by the superior interaction of I_{2 X} M_{2 X} W₃ because it resulted in the highest irrigation water productivity of rice to be 0.98 kg m^-3.
