Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).

<p>Plankton is aquatic organism that can be utilized as natural food. Hard-lipped barb is one of herbivorous fish that most of its life using plankton as its food source. Growing phytoplankton in pond can be conducted by providing nutrient source, such as fertilizing.  In this study, we examined the growth of hard-lipped barb larvae related to the existence of natural food in different fertilized ponds.  Four types of fertilizer were applied i.e. 100% organic fertilizer (PO), mixing of 85% organic and 15% inorganic fertilizer (PCa), mixing of 60% organic and 40% inorganic fertilizer, and 100% inorganic fertilizer (PA). Hard-lipped barb larvae were put into ponds after fertilizing process. Plankton was observed in ponds and larval intestines (Index of Preponderance and Ivlev Index). The growth of hard-lipped barb larvae was also observed. The result showed that larvae tend to utilize phytoplankton from the class of Bacillariophyceae and zooplankton in the early of its life. Utilizing plankton with those compositions as natural food in the early period generates a good growth performance.  The best performance of growth was shown by larvae in PA treatment which utilized most on zooplankton in the early period.</p> <p>Key words: fertilizer, natural food,<em> </em>hard-lipped barb<em>, </em>plankton</p> <p> </p> <p>ABSTRAK</p> <p>Plankton merupakan organisme akuatik yang dapat digunakan sebagai sumber pakan alami. Ikan nilem merupakan salah satu jenis ikan herbivora yang hampir sepanjang hidupnya memanfaatkan plankton sebagai sumber makanannya. Cara untuk menumbuhkan fitoplankton di kolam adalah dengan menyediakan sumber nutrien, di antaranya melalui pemupukan. Oleh karena itu, penelitian ini dilakukan untuk mempelajari tingkat pertumbuhan larva ikan nilem berkaitan dengan keberadaan pakan alami yang ditumbuhkan pada media dengan jenis pupuk berbeda. Dalam penelitian ini diterapkan empat jenis pupuk berbeda, yaitu 100% pupuk organik (PO), campuran 85% pupuk organik dan 15% pupuk anorganik (PCa), campuran 60% pupuk organik dan 40% pupuk anorganik, dan 100% pupuk anorganik (PA).  Larva ikan nilem ditebar di kolam setelah proses pemupukan. Pengamatan dilakukan terhadap keberadaan plankton di kolam dan di usus (Indeks <em>Preponderance</em> dan Ivlev).  Di samping itu juga dilakukan pengamatan pertumbuhan larva.  Berdasarkan hasil penelitian diketahui bahwa fitoplankton dari kelas Bacillariophyceae dan zooplankton banyak dimanfaatkan oleh larva di awal hidupnya.  Pemanfaatan plankton dengan komposisi tersebut sebagai pakan alami di awal masa pemeliharaan menghasilkan pertumbuhan yang baik.  Larva dengan pertumbuhan yang paling baik ditunjukkan oleh perlakuan PA yang memanfaatkan zooplankton lebih besar di awal masa pemeliharaan.</p> <p>Kata kunci: ikan nilem, pakan alami, plankton, pupuk</p>

The study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig manure, PiM) applied at 15 t ha-1 equivalent rate on the soil and growth performance of okra grown in a degraded ultisol. The treatments (CoM; CoM; PiM and Control unamended) were laid out in a completely randomized design and replicated three times. Animal manure application had significant effects on soil properties. Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil. It is recommended that farmers use ample (15 t ha-1) ) quantity of animal manures to increase their crop yields, which invariably will enhance their income. Keywords: Soil fertility, organic fertilizers okra growth, okra yield response, farmers okra yeild.

Implications of dietary phenolic compounds for human health and disease prevention have been indicated by a body of literature. A greenhouse pot study was performed to investigate the impacts of fertilizer source and preventive insecticide application on phenolic compound levels in pac choi [Brassica rapa (L.) cv. Mei Qing]. A two-way randomized complete-block design with five replications was used in this experiment. Fertilizer source consisted of two levels: conventional fertilizer (pre-plant application of Osmocote slow-release fertilizer), and organic fertilizer (pre-plant application of vermicompost and fertigation with compost tea and fish emulsion). Insecticide application consisted of three levels: organic (pyrethrin) vs. conventional (permethrin), and a plain water control. At harvest, total phenolics and individual phenolic compounds in pac choi leaves (blades) were analyzed by Folin assay and HPLC, respectively. Head weight of pac choi was significantly higher under conventional fertilizer treatment, while it was not affected by insecticides. Total phenolic content of pac choi was significantly increased by organic fertilizer treatment. HPLC results indicated that organic fertilizer treatment resulted in significantly higher levels of individual phenolic compounds, including chlorogenic acid and ferulic acid. In contrast, preventive insecticide application showed little effect on the phenolics in pac choi. Correlation analysis excluded the influence of plant size (head weight) on phenolic content in pac choi. Differential N-forms, rates of nutrient release, and/or variable nutrient content in organic and conventional fertilizer treatments may contribute to elevated phenolic content in organically fertilized pac choi.

[CHLOROPHYL CONCENTRATION AND YIELD OF PAKCOY (Brassica rapa L.) AFTER TWO YEARS OF BIOCHAR AND ORGANIC FERTILIZER APPLICATION IN ENTISOLS]. While nitrogen is necessary throughout the growth of vegetable plants, N deficiency disrupts chlorophyll formation, and hence, affecting the photosynthesis process. This study aimed to study the impact of the use of biochar and organic fertilizers on chlorophyll content and yield of Pak coy mustard in the third planting season in Entisols. This research was conducted in Bawang Hamlet, Tunggulwulung Village, Malang City. The first and second planting seasons, were May-November 2017 and August 2018-January 2019, respectively. Research on the third planting season was carried out in July-August 2019 without nitrogen fertilization. The research was arranged in a randomized block design, consisting of controls (Kl), chicken manure (A), compost (K), rice husk biochar (S), rice husk biochar + chicken manure (SA), rice husk biochar + compost (SK). The results showed that after two years of application, biochar and organic fertilizers had a positive impact on the increase in yield of Pakcoy even though fertilizer was not provided. The application of biochar and compost provided the best residual effect on the total chlorophyll of Pakcoy mustard.
