IMPACT OF DIFFERENT LIQUID MANURE ON GROWTH AND YIELD OF WATER SPINACH

The experiment was conducted at Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of September to October 2023. The single factor experiment was laid out in randomized complete block design (RCBD) with three replications to study the growth and yield of water spinach. The experiment was consisted of five treatments namely; T₁: Control (only same amount of water spray); T₂: Vermi Tea (VT), T₃: SAU-MLM, T₄: SAU-NLM and T₅: SAU-PLM. Treatments were applied to plants four times every 10 days interval from 7 days after seed germination. A significant variation was found among the parameters. The average tallest plant (42.1 cm), maximum SPAD Value (40.9), maximum leaf area (42.1 sq cm), Root length (12.1 cm) maximum root number (35.0), highest yield per plant (57.0 g) and highest yield per ha (11.1 ton) was found in (T₅) application while shortest plant (24.3 cm), minimum SPAD Value (32.8), minimum leaf area (12.8 sq cm), lowest yield per plant (12.0 g) and the lowest yield per ha (4.4 tons) was found in (T₁). Therefore, it can be concluded that SAU-PLM is easy and effective liquid manure that has the potential to increase the entire growth and yield of water spinach.
