Table 1. Correlation coefficients between pairs of climate variables during cool and warm cropping seasons.

		Cool cropping season					Warm cropping season
	Climate variable	ΔT	ΔDTR	ΔR		Climate variable	ΔT	ΔDTR	ΔR
Cool cropping season	ΔDTR	0.282**	–	–	Warm cropping season	ΔDTR	−0.220*	–	–
	ΔR	−0.403**	−0.308**	–		ΔR	−0.179	−0.274*	–
	ΔS	0.426**	0.496**	−0.561**		ΔS	−0.038	0.105	−0.186

Note:

ΔT, ΔDTR, ΔR, and ΔS represent the first difference values of average temperature, diurnal temperature range, rainfall, and sunshine duration, respectively. ** and * Represent p-value < 0.01 and 0.05 < p-value < 0.1, respectively.
