Performance of Tomato Applied with Bokashi Using Various Substrates

Abstract

This study was conducted to evaluate the effect of Bokashi using various substrates on the performance of tomatoes. Three treatments were tested, namely: rice bran (A), coco dust (B), and sawdust (C). The experimental treatments were replicated five times and were arranged in Randomized Complete Block Design (RCBD). Plots measuring 4 x 4 m were made and seedlings were transplanted at 50 x 50 cm distance. Recommended practices for tomato production were followed. Bokashi was applied at a rate of five tons per hectare. Growth data were collected and recorded every week and yield data at harvest. Samples of soil and the different treatments were prepared and submitted to the Regional Soils Laboratory for analysis of soil pH, % organic matter, available phosphorus and exchangeable potassium. The initial fertility condition of the experimental area was generally described as basic or alkaline with low organic matter, available P and exchangeable K. Results showed that the growth components of tomato were not affected by the application of bokashi with different substrates. The length of fruit was significantly affected by the kind of substrates, while all other yield parameters have comparable results. Coco dust and sawdust are potential substitutes for rice bran as substrates for bokashi.
