Abstract
A pot experiment was conducted to investigate the effect of coconut peat on growth and yield response of Ipomoea aquatica for Pirojpur soil series during the period of 24 th May to 25 th June, 2017. The experiment was laid to fit a completely randomized design (CRD) with five treatments [control (T 0 ), 1000 kg coconut peat ha -1 (T 1 ), 1500 kg coconut peat ha -1 (T 2 ), 2000 kg coconut peat ha -1 (T 3 ) and 2500 kg coconut peat ha -1 (T 4 )] each having three replications for this experiment. After plant harvesting, the laboratory investigation was carried out in the Soil, Water and Environment Discipline, Khulna University, Khulna, Bangladesh. Yield contributing characters like number of leaves, fresh weight and dry weight were significantly (P < 0.05) influenced by different treatments. By contrast root length and shoot length were insignificantly varied compared to control (T 0 ) treatment but from the eye observation and analytical data confirm increasing trend for the application of coconut peat. Among the five treatments applied T 4 treatment (2500 kg coconut peat ha -1 ) has shown highest response to plant growth due to nutrient availability of the soil. The sequence of response was in the order T 4 > T 3 > T 2 > T 1 > T 0 and significantly (P < 0.05) difference in plant growth from the control (T 0 ).
