Description
A field experiment to assess the effect Palm Bunch Ash (PBA), at various levels (0, 2, 4t/ha) on the pH of soil and growth of Cucumis sativus at the Teaching and Research Farm, Rivers State University, Port Harcourt, was conducted. Soil samples (0 – 15cm) before and after application, from the experimental plots were collected, and analyzed with standard methods for pH and nutrients. Also, Palm Bunch Ash (PBA) sub-sampled, and analyzed with standard methods for pH used for the experiment. A total of 9 treatments were used with A0 (Control), A2 and A4, where A represents PBA, and the subscripts 0, 2 and 4 represent the treatment levels. The experiment was a 1x3 factorial in Randomized Complete Block Design (RCBD) with 3 replicates. 18 seeds of cucumber (2 per hole) from NSPRI, Rumueme, Port Harcourt were planted on each treatment plot of 2 x 2m at a plant spacing of 45 × 45cm. Thereafter, it was thinned to one (1) per hole after emergence. This implies that, there were a total number of 10,000 plants per hectare. Growth parameters include shoot height (cm), 3, 6 and 9WAP, and Number of leaves, 3, 6 and 9WAP. Data generated from field were subjected to one-way ANOVA test using the Minitab package and the means were separated using Tukey’s Honest Significant Difference at 95% probability. The results revealed that pH increased (p<0.05) as the amendment level increased in the treated soil with the highest 6.00 of 4t/ha. Also, there was significant effect (p<0.05) on growth, as the PBA level increased in the treated soil with the highest values 13.97cm recorded in 2t/ha, and 48.13cm and 77.90cm recorded in 4t/ha for 3, 6, and 9WAP. Similarly, for number of leaves, the highest values were recorded in 4t/ha, also for 3, 6, and 9WAP. Hence, PBA is recommended as good amendments for acid soil neutralizer and nutrient buffer and supplier to the soil and ultimately to plants.
