Seven genotypes (G), namely G1, G2, G3, G4, G5, G6 and G7 which were selected for yield, seed weight, number of productive panicles,panicle weight, shoot and root length, and the original population were planted in a field at different planting data (D), namely April 29; May 6, May 13 and May 20. Growth responses for leaf area, dry weight of leaf, stem and root were measured at 2, 3, 5, and 6 weeks after transplanting. Early planting inhibited growth of all genotypes in early stage but not differed in the late stage. Significant growth response of genotypes was caused mainly by the difference of planting date. Significant yield and yield components response was caused by the difference of genotypes. No significant G x D interaction for growth, yield and yield components, except for leaves area was observed. Genotypes selected for yield, number of productive panicles and panicle weight were relatively stable in different planting date and might be consider to be adapted for early spring planting. Photoperiod sensitivity was evidenced and pearl millet might be consider as facultative short-day plant
