USING OF SOLID PALM OIL WASTE FERTILIZER TO IMPROVE GROWTH AND YIELD OF EGGPLANT (SOLANUM MELONGENA L.)

Abstract

This study aims to determine the effect of applying palm solid waste fertilizer on the growth and yield of eggplant (Solanum melongena L.). The study used a randomized block design consisting of 1 (one) factor, namely the palm oil solid waste fertilizer factor which consisted of 6 treatment levels, namely p0: control (without solid fertilizer); p1 (1.4 kg/m2); p2 (2.4 kg/m2); p3 (3.4 kg/m2); p4 (4.4 kg/m2); and p5 (5.4 kg/m2) which was repeated 4 times. The results showed that the treatment of palm solid waste fertilizer had a significant effect on all parameters except flowering age. The highest yield at plant height at 84 days after planting (DAP) was obtained in the p4 treatment (4.4 kg/m2) with an average value of 62.56 cm and the lowest in the p0 treatment (control) with an average value of 18.31 cm. The highest number of leaves aged 84 DAP was obtained in the p4 treatment with an average value of 87.50 strands and the lowest in the p0 treatment (control) with an average value of 16.00 strands. The flowering age of the control plants was slower, ie 54 DAP compared to the plants given palm solid waste fertilizer in the p4 treatment which reached 42 DAP. The highest number of fruit and eggplant weight were obtained in the p4 treatment, namely 7.31 fruit and 25.67 t.ha-1, whereas the lowest was in the p0 treatment, namely 0.25 fruit and 0.88 t.ha-1.
