Extract

In the Sudan, rice has been grown since 1905, but on only a very limited acreage, and information about methods of production are lacking.

With the introduction of a large number of rice varieties into the country (Moir, 1965, 1966, 1967, 1968), an irrigation and drainage experiment was initiated by Hack (1968) at Kenana Research Station (KRS). Using the variety H.D.41, he found no advantage from very short watering intervals (1–3 days) in the early stage of growth, i.e. up to the boot stage, whereas better results were obtained from watering every 6 days in the early stage, to obtain a large number of flowers, and every other day in the late stage, to obtain relatively low sterility and large grains.
