Table 1 Effect of bamboo species, season of the year and their interactions on growth parameters of bamboo species (ANOVA).

Parameters	New emergent shoots			Culm Height
	F	P	Partial Eta Squared	F	P	Partial Eta Squared
Bamboo species (BS)	11.89	0.00	0.10	5.54	0.00	0.05
Season of the year (SY)	19.23	0.00	0.16	24.72	0.00	0.20
BS X SY	3.31	0.00	0.09	0.79	0.07	0.02

Table 2 Mean values of new emergent shoots and culm height (m) for each bamboo species across different seasons.

Species	Growth parameters	Season				P value
		Summer	Autumn	Winter	Spring
Bambusa bambos	New emerge shoots	4.27^a	2.21^a	2.45^a	1.82^b	0.04
	Culm height (cm)	216.55^a	152.17^a	40.73^b	163.82^a	<0.001
Bambusa vulgaris	New emerge shoots	3.67^a	2.54^a	2.18^a	0.64^b	0.02
	Culm height (cm)	272.67^a	118.23^b	33.82^b	120.18^b	<0.001
Oxytenanthera abyssinica	New emerge shoots	11.18^a	4.16^b	4.25^b	1.17^b	<0.001
	Culm height (cm)	288.82^a	208.63^b	81.50^b	234.00^b	<0.001
Phyllostachys edulis	New emerge shoots	5.40^a	2.96^a	1.67^b	0.29^b	0.01
	Culm height (cm)	202.40^a	148.83^a	74.83^a	158.43^a	0.08

Different letters in the same row indicate significant differences among growth parameters in the season at p ≤ 0.05

Table 3 Means Comparisons between treatments at 0.05 significant levels

Treatments	Av. NES	Av. CH (m)	Av. CD (cm)	Av. IL (cm)	Duration
B. bambos	2.44b	2.26a	1.99a	21.55a	4-years
B. vulgaris	2.33b	2.35a	2.31a	21.00a	4-years
O. abyssinica	4.67a	2.05a	1.37ab	18.82ab	4-years
P. edulis	2.67b	1.42b	0.31b	15.17b	4-years
P Value	<0.001	0.001	0.014	0.001

Different letters indicate significant differences between bamboo species growth parameter at p ≤ 0.05

NB: Means with the same letter are not significantly different. Av. NES = Average of New Emerging Shoots; Av. CH (m)=Average of Culm height in meter; Av. CD (cm)= Average of Culm Diameter in centimeter; Average internode length
