@article{Yaowarat Wongsrisakulkaew_2017, title={EFFECT OF BIO-EXTRACTS ON GROWTH AND QUALITY OF LETTUCES}, volume={13}, url={https://geomatejournal.com/geomate/article/view/1385}, abstractNote={<p>The aim of this work was to determine the effects of bio-extracts on growth and quality of <br>lettuces. The experimental design was RCBD (Randomized Complete Block Design) with 3 treatments and 4 <br>replications include chemical fertilizer (16-16-16), bio-extract of fish meal and bio-extract of soybean meal. This <br>experiment was conducted at The Division of Crop Production, Faculty of Agricultural Technology, <br>Rajamangala University of Technology Thanyaburi. The result of this study showed that the vegetative yield of <br>butter head and red oak lettuces treated with bio-extract of fish meal and soybean meal was similar to chemical <br>fertilizer. There was no statistically difference on the vegetative yield of red coral and green oak lettuces. Both of <br>bio-extract of fish meal and soybean meal could increase the color of leaves in red oak and green oak lettuces <br>than chemical fertilizer. Bio-extract of fish meal could increase the color of leaves in red coral and butter head <br>lettuces than bio-extract of soybean meal and chemical fertilizer respectively.</p>}, number={40}, journal={GEOMATE Journal}, author={Yaowarat Wongsrisakulkaew}, year={2017}, month={Oct.}, pages={155–159} }
