Abstract:
A field experiment about the effect of dry spells on the growth parameters and chlorophyll content of wheat was conducted during Rabi 2020 at the Instructional cum Research Farm, Shaheed Gundadhoor College of Agriculture and Research Station, Jagdalpur, Chhattisgarh to study the effect of dry spells on growth parameters and chlorophyll content of wheat. The experiment was laid on Randomized Complete Block Design (RBD), replicated 4 times with 5 treatments i.e., T₁ (25 days dry spell at 45 days after sowing), T₂ (20 days dry spell after flower initiation), T₃ (20 days dry spell after 50% flowering), T₄ (Irrigation at 30% moisture in soil) and T₅ (Control). Dry spells significantly reduced the plant height, number of tillers per plant, number of leaves as well as the dry matter. Similarly, the content of chlorophyll A and B were significantly reduced during and after imposition of dry spells. Maximum reduction of all the growth parameters as well as chlorophyll content were recorded in treatment T₅ (Control). Hence it was concluded that treatment T₄ with irrigation at 30% moisture in soil performed better than all other treatments.
