Description The study of phenology of wheat (Triticum aestivum L. emend. Fiori & Paol.) crop in relation to various euergy summation iudices, viz accumulated growing degree-days, accumulated helio-thermal units, cumulative solar radiationand cumulative pan evaporation, for 8 crop seasons of 1986-87 to 1993-94 was conducted at Ludhiana. A comparison ofvarious agro-climatic indices revealed that accumulated growing degree-days can be used as the best index to predictvarious phenophases under Punjab conditions, as it gave the lowest coefficient of variation under early-, normal- as wellas late-sown conditions, From sowing to complete emergence and also during intennediate phenophases representingreproductive phase, the delay in sowing reduced the cumulative energy attained, but no such trend was observed during the vegetative phase.
