Experiments conducted for several cropping seasons on the montmorillonitic Maahas clay soil at the IRRI farm demonstrate that continual flooding is not essential for high grain yield but flooded rice can tolerate at least 15cmif the improved varieties are grown. Tall varieties like H-4 has less adaptability under wide range of water management conditions than semidwarfs like IR8. With adequate water supply, 5 to 7 cm of water is desirable on most soils for best weed and insect control with granular chemicals, forhigh nutrient availability, and for minimum losses of nutrients from fertilizer and soil. If rainfall does not provide supplemental water, irrigation intervalslonger than 8 days reduce grain yield under a rotational irrigation system. Varieties like IR5 that have a long growth duration were least sensitive to moisture stress imposed by long irrigation intervals. This is because IR5 will generally recover from high moisture stress for a short period or low moisture stress for a long period. An experiment with IR20 indicates that the furrow irrigation of nonpuddled soil does not provide more efficient water use in rice compared with rice grown on puddled lowland soil.

Botswana currently depends on imports for 80-90% of its vegetable consumption. The Botswana Government is, however, trying to encourage local production for increased self- sufficiency. Botswana is a semi-arid country and both population and water sources are widely scattered. Often the yield of a water source limits the area that can be irrigated at a particular place. Consequently, vegetable farms are small, usually less than five hectares in size. The scattered population leads to problems with marketing. It is uneconomic for farmers to transport small quantities of produce over long distances to find a market. The Department of Agricultural Research is therefore pursuing the "market garden" approach, with individuals or groups of farmers groups of farmers growing a range of produce to try and satisfy their local market. Production is carefully planned to provide as continuous a supply as possible of the major vegetable crops. Irrigated plots have been established (or are planned) in different climatic areas of the country. These are run as "commercial" market gardens and data on costs of production, yields and returns recorded. Information on crop growth and profitability in different areas and at different times of year is obtained. Sample data are presented and problems experienced with these units are discussed.
