Proven benefits of delayed permanent water in rice
Four years of investigation into delaying the application of permanent water on drill sown rice has proven the technique to be a viable water management option. Research conducted on both red-brown earth and self-mulching clay soils has shown that rice copes well with the moisture stress and that delayed permanent water leads to considerable water savings with only a small decline in grain yield.
