Effect of Worm Fertilizer and Em4 on the Growth and Production of Red Spinach (Amaranthus Tricolor L.)

This study aims to determine the influence of kascing fertilizer and EM4 (Effective Microorganism 4) on the growth and production of red spinach (Amaranthus tricolor L.). This research was conducted at the Agricultural Extension Center of Sukodono Village, Sukodono Subdistrict, Sidoarjo Regency and observations continued in the agrotechnology laboratory of Muhammadiyah University sidoarjo. From February 2021 to March 2021. This study used a Randomized Group Design (RAK) with 11 treatments, namely control, chemical fertilizer, kascing 100 grams/tile + EM4 10ml/tile, kascing 100 gram/tile + EM4 15ml/tile, 100 gram/tile kascing + EM4 20ml/tile, 200 gram/tile + EM4 10ml/tile, 200 gram/tile kascing + EM4 15ml/tile, kascing 200 grams/tile + EM4 20ml/tile, 300 gram/tile kascing + EM4 10ml/tile, 300 gram/tile kascing + EM4 15ml/tile, 300 gram/tile kascing + EM4 20ml/tile, and repeated 3 times to get 33 units of experiment satian. The observed variables are: plant height (cm), stem diameter (mm), leaf area (cm2), number of leaves (strands), plant weight (grams), plant index (grams). The data was analyzed using ANOVA followed by BNJ test at 5% test level. The results showed that the combination of kascing fertilizer and EM4 had a real effect on the height of the plant, the diameter of the stem, the area of the leaves, and the number of leaves, and had no noticeable effect on the weight of the crop and the harvest index, the best results were shown in the treatment of kascing 300 grams /tile + EM4 20ml / tile, while the less maximum results were shown in the treatment of control on all observation parameters.
