“…Although they are needed in small amounts, these elements are absolute and can cause plants to become less fertile if they are not met for plants (Omaranda et al, 2016). In line with Stevanus et al (2015) stated that the deficiency of micro nutrients (Zn, Mo, Fe, Mn, Co, and B) can affect the vegetative growth of plants. Such as Zn deficiency will result in stem segments and the division of meristem cells becomes imperfect.…”

Efforts to increase the production of kale with a hydroponic cultivation system, the addition of nutrients is absolutely necessary for both macro and micronutrients. In addition to using AB mix nutrients, the use of other alternative fertilizers in hydroponic cultivation needs to be a big concern so that it can suppress the use of inorganic fertilizers. The purpose of this study was to determine the effect of giving various types of nutrient compositions AB mix and cow urine on the growth and yield of water spinach plants with the Nutrient Film Technique (NFT) hydroponic system . The design used in this study was a single factor randomized block design (RAK) with 4 levels of treatment of various types of hydroponic nutrients consisting of N 1 (100% AB mix ), N 2 (75% AB mix + 25% Cow Urine), N 3 (50% AB mix + 50% Cow Urine), and N 4 (25% AB mix + 75% Cow Urine). The results of this study showed that the provision of various nutritional compositions significantly affected the growth and productivity of kale except for the variable number of books. Plant water spinach given nutritional composition N 4 (25% AB mix + 75% of cow urine) showed a markedly lower in all the observed variables, while the growth and productivity of water spinach best shown in the nutritional composition of 100% AB mix but not significantly different the nutritional composition treatment was 75% AB mix + 25% cow urine and 50% AB mix + 50% cow urine. The results of this study also show that the use of cow urine has not been able to replace the use of AB mix nutrition.

“…Defisiensi unsur mikro pada tanaman terbagi menjadi dua fase, yaitu fase defisiensi unsur mikro yang gejalanya dapat terlihat dari visualisasi tanaman karet dan defisiensi unsur mikro yang tidak dapat dilihat melalui visualisasi atau yang disebut dengan "hidden hunger" (Gambar 2). Hidden hunger ini hanya dapat diketahui melalui analisis daun di laboratorium (Stevanus et al, 2015). Besi Tersedia (Fe) DTPA-AAS mg/Kg 15,7 Keterangan : hara mikro jika konsentrasinya kecukupan berada pada kisaran dalam jaringan tanaman sebesar ≤0,01% (100 ppm) (Harmsen, 1977).…”

Fertility and continuity of results are needed in pepper cultivation, so the right compatibility of nutrients is needed. Micronutrient observations are often not carried out regularly and tend to lag behind macronutrients, even though they are equally essential. Symptoms will be visible visually on the leaves and it is important to know that identifying nutrient symptoms is important. The leaf samples were represented by 20 old leaves and 20 young leaves which were observed visually by comparing them based on the nutrient symptom table, then the micronutrients of the young leaf tissue were analyzed. Based on the visuals of the leaves, symptoms of micronutrients were found dominantly found in young leaves. The diagnosis results based on visual symptoms were that pepper plants with the criteria for healthy growth still found symptoms of Fe deficiency in the form of yellowing in young leaves and also in old leaves, symptoms of Zn toxicity in the form of chlorosis between the leaves. young and Kahat B which shows that there are several young leaves which are also darker in color than normal young leaves. Based on analysis of the micro nutrient content found in young leaf tissue, the content of Cu, available Fe, Mn, Zn, B, Mo is below 100 ppm (100 mg/Kg), this figure shows that it is still in the low category.

“…Unsur N, P dan K yang terkandung dalam pupuk kandang dapat meningkatkan pertumbuhan vegetatif sehingga meningkatkan bobot segar dan bobot kering kering tanaman (Fitriyanti 2014). Kandungan unsur Fe pada pupuk hijau dan pupuk kandang bermanfaat dalam mengaktifkan beberapa enzim dan merupakan komponen penyusun protein yang memengaruhi pertumbuhan tanaman (Stevanus et al 2015). Pemakaian pupuk organik dapat meningkatkan produksi total fenol, flavonoid, asam askorbat, saponin dan glutha-thione pada tanaman Labisia pumila dibandingkan dengan penggunaan pupuk kimia.…”

Echinaceae is introduced medicinal plant as immunomodulator. The high demand of echinaceae as raw material for immunomodulatory herbal medicine by the industries, requires the increase in quantity and quality of cultivated echinaceae. Thus, the use of fertilizer is necessary. However, to ensure the safety of raw materials for herbal medicine industry, the use of organic fertilizer becomes one of the important components. Organic fertilizer used can be in the form of solid fertilizer such as dung manure, compost and green manure. Various plants can be utilized as a source of green manure such as Tithonia diversifolia, because of its high N content. The aim of this research was to evaluate the effect of the dosage of dung manure and green manure from T. diversifolia on echinaceae biomass and echinacoside contents. The research was arranged in Factorial Randomized Block Design with two treatments, three dosages of dung manure (P) 0; 2.5; 5 ton.ha-1, and three dosages of green manure from T. diversifolia (T) 0; 10 and 20 ton.ha-1. The treatment combinations were repeated three times. The results showed that there was no interaction between T. diversifolia green manure and dung manure usage. The use of T. diversifolia fertilizer alone was not evidently increased the fresh weight of biomass at 20 ton.ha-1. The use of T. diversifolia and dung manure showed no significant effect on echinacoside content.
