H.  aWater use and growth of groundnut at Samaru, Northern Nigeria.  c1975  aWater requirement and pattern of crop growth of a medium to long season groundnut crop were assessed at Samaru (11Graus 11' N, northern Guinea savanna). Nigeria. Although the crop was sown two weeks later than the average earliest date of sowing, the pattern of availability of water at Samaru appears to be favourable enough to accomodate such a delay in sowing without experiencing real difficulties with lifting and harvest. Seasonal energy conversion was 0.6 per cent of the total incoming radiation, while the season crop water requirement was 43.8cm corresponding to a crop water use efficiency of 518g of water per gramme of dry matter.  aNigeria  awater  aÁgua  aAmendoim  aCrescimento  aGroundnut  aGrowth  aUse  aUso1 aKOWAL, J.
