Abstract
The objective of this study was to determine the effect of biochars and inorganic fertilizer application rates on soil nutrients and growth characteristics of lettuce. The experimental design was Randomized Block Design (RBD) in a 2x4 factorial scheme, with 2 types of biochar ( rice husk biochar and wood biochar), 4 rates of inorganic fertilizer (0, 100, 200 and 300 kg ha-1) phonska. Both of these factors were combained and each treatment repeated three times. Data collected were analysed statistically by using analysis of variance at 5% level and significant treatments effect were separated with honestly significant difference at P 0.05. Plant height, number of leaves, leaf area, total shoot fresh were test as well as soil nutrient status. The use of biochar types did not influence plant growth and soil nutrients status including soil pH, total-N, available-P and exchangeable-K. However, inorganic fertilizer application directly increased all the soil characteristics were evaluated, and also increased the total fresh weight by increasing the plant height, number of leaves and leaf area of lettuce as commercial characteristics for consumers. Application of 200 kg ha-1 inorganic fertilizer should be sufficient to improve growth characteristics of lettuce.
