Description Field experiments were conducted during 2009-2010 and 2010-2011 to study the growth
performance of white clover (Trifolium repens L.) under different temperature regimes over the crop
growth period. The agroclimatic indices for temperature viz., growing degree days (GDD), heliothermal
units (HTU) and photothermal units (PTU) were computed for different phenological stages of the crop.
Changes in weather parameters concomitant to different sowing time caused significant variation in the
performance of the crop. The results indicated that the early sown crop had longer crop span (205 days)
than the late sown (142 days). From emergence to seed maturity, white clover accumulated GDD of
2314±72 °C days, HTU of 17791±409 °C days hour and PTU of 29412±742 °C days hour, respectively.
Positive correlations were found between fresh leaf weight, fresh stem weight and fresh root weight for
GDD, HTU and PTU.
