On loam soils at an altitude of 850 m in Meghalaya [India] 'Sonalika' wheat (T. aestivum Linn. emend. Thell.) gave the highest yield (36 q/ha) when it received 4 irrigations, 1 each at crown-root initiation, jointing, flowering and milk stages. Two irrigations either at crown-root initiation + flowering and milk stages. two irrigations either at crown-root initiation + flowering or jointing + milk stage also gave a substantial yield (30 q/ha). Water use increased with frequency of irrigation, but its efficiency was less.
