Abstract:
The investigation entitled “effect of different levels of saline water irrigation and mulching on growth of gaillardia under clay soil” was conducted during December 2021-22 at Floriculture Research Farm, ASPEE College of Horticulture, Navsari Agricultural University, Navsari. The experiment was laid out in Split Plot Design consisting sixteen treatment combinations, with four levels of saline water irrigation i.e., Best available water (S₀), 4 dS/m saline water irrigation (S₁), 6 dS/m saline water irrigation (S₂) and 8 dS/m saline water irrigation (S₃) and four levels of mulching i.e., no mulch (M₀), paddy straw mulch (M₁), sugarcane trash mulch (M₂) and silver plastic black mulch (M₃). The experiment was replicated four times. The plant height (10.69 and 47.69 cm at 30 DAT and 60 DAT, respectively), fresh weight of plant (1.464 kg) and dry weight of plant (267.67 g) were found maximum in gaillardia plants irrigated with best available water (S₀) was found statistically at par with 4 dS/m level of saline water irrigation for all vegetative parameters. Plants mulched with silver black plastic resulted maximum plant height (11.63 cm and 48.57 cm at 30 DAT and 60 DAT, respectively), fresh weight of plant (1.521 kg) and dry weight of plant (282.49 g). Gaillardia grown with best available water along with silver black plastic mulch (S₀M₃) resulted maximum plant height (12.74 cm and 53.56 cm at 30 DAT and 60 DAT, respectively), fresh weight of plant (1.579 kg) and dry weight of plant (297.32 g).
