The present study aimed to evaluate the use of the babassu decomposed stem under different proportions in substrate composition for the vegetative propagation of Euphorbia splendens. The experiment was conducted in a greenhouse and we used a completely randomized design with six treatments and four repetitions. Six types of substrates were formulated using a mixture of babassu decomposed stem (BDS) and soil (SL) in the proportions of 100% SL, 20:80 % BDS:SL, 40:60 %, BDS:SL, 60:40 % BDS:SL, 80:20 % BDS:SL and 100 % BDS. The seedlings were evaluated at 45 days after cutting by measuring the diameter of the longest shoot, number of leaves, number of shoots, root length, root volume, largest shoot length, fresh weight of the aerial part, root fresh weight, dry weight of the aerial part, and root dry weight. The treatments that presented normality and homoscedasticity were submitted to simple linear regression analysis. The proportion of the substrate of 20: 80% BDS: SL has a greater length of the largest shoot about the substrate 80:20% BDS: SL. The diameter of the largest sprout, the number of leaves, and the root length decreased due to the increase in the proportion of babassu decomposed stem in the substrates. The production of seedlings using cuttings of Euphorbia splendens is facilitated by the fact that it is a species with easy rooting, therefore, it is not necessary to use substrates with proportions of babassu decomposed stem and soil for its vegetative propagation.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.
