In the present paper, products obtained from a blue-green microalga Spirulina platensis filtrate (applied for seed soaking and for foliar spray) and homogenate (used for seed coating) were tested in the cultivation of radish. Their effect on length, wet mass, multielemental composition and the greenness index of the radish leaves was examined. Multi-elemental analyses of the algal products, and radish were also performed using inductively coupled plasma-optical emission spectrometry (ICP-OES). The best soaking time, concentrations of filtrate and doses of homogenate were established. The longest and heaviest plants were observed for homogenate applied at a dose of 300 µL per 1.5 g of seeds and 15% of filtrate applied as foliar spray. The highest chlorophyll content was found in the group treated with 100 µL of homogenate and 5% of filtrate. In the case of soaking time, the longest plants were in the group where seeds were soaked for 6 h, but the heaviest and greenest were after soaking for 48 h. The applied algal products increased the content of elements in seedlings. Obtained results proved that algal extracts have high potential to be applied in modern horticulture and agriculture. The use of Spirulina -based products is consistent with the idea of sustainable agriculture that could help to ensure production of sufficient human food to meet the needs of rising population and protection of the environment.

“…Apart from animal-and plant-derived biostimulants, numerous seaweeds have been reported to improve plant growth due to their biostimulation potential. A homogenate from Baltic seaweeds was shown to have improved the seedling vigour and growth of radish [9]. Additionally, protein hydrolysates derived from legumes and seaweed extracts from Ecklonia maxima resulted in improved development and metabolites abundance in spinach grown under greenhouse conditions [10].…”

Biostimulants are the next-generation choice for sustainable agricultural production and are gradually becoming an alternative to synthetic chemicals. Various botanicals are proposed to exert stimulatory effects, and garlic allelochemicals are among such botanicals; however, a peer-reviewed scientific evaluation is required to understand garlic-derived substances such as biostimulants. Current studies were therefore performed to identify the bioactivity of garlic extract as a biostimulant to improve crop quality, alter its physiological potential, and prime its defense responses against pathogenic fungal infections. 100 µg mL−1 aqueous garlic extracts (AGE) in consort with 1 mM of acetyl salicylic acid (ASA) and distilled water as a control treatment were applied to eggplant and pepper seedlings as foliar application and fertigation methods. The results revealed stimulatory responses in the growth of the vegetables with improved plant height, number of leaves, root growth, fresh and dry weight, etc., due to AGE and ASA applications. Moreover, significant alterations were indicated in plant metabolites such as chlorophyll, carotenoids, and soluble sugars. Additionally, stimulation of the antioxidant enzymes such as superoxide dismutase (SOD) and peroxidase (POD), as well as the root activity of these plants, was observed after treatment. Application of AGE and ASA also exerted priming effects on pepper plants, inducing defense responses prior to Phytopthora capsici inoculation, and the treated plants therefore successfully resisted infection through activated antioxidant systems, and probably carotenoid and other protectory metabolites. Stress-induced H2O2 content was extremely low in the treated plants, indicating successful resistance against pathogenic infection.

“…Biostimulan tanaman merupakan bahan yang mengandung satu atau lebih senyawa dan/atau mikroorganisme yang diformulasikan untuk menstimulasi proses fisiologis tanaman berkaitan dengan efisiensi pengambilan dan pemanfaatan nutrisi oleh tanaman, serta mekanisme pengaturan ketahanan terhadap kondisi stres (biotik dan abiotik), sehingga dapat mengoptimalkan produksi tanaman tersebut dengan jumlah kebutuhan aplikasi yang sedikit (Sharma et al, 2016;Jardin, 2015;Yakhin et al, 2017). Biostimulan dibuat dari sumber bahan baku melimpah dan murah, namun kaya akan kandungan bioaktif sehingga dapat dikembangkan menjadi suatu teknologi organic farming yang berkelanjutan baik untuk bidang pertanian dan hortikultura (Michalak et al, 2017;Hamed et al, 2018). Kultur in vitro dengan aplikasi biostimulan pada kultur hipokotil tanaman terong juga menunjukkan efek yang sama dengan fitohormon sehingga mempercepat proses propagasi massal dengan tingkat keberhasilan tinggi (Satish et al, 2014).…”

“…Jika dilihat pada data hasil pengamatan terhadap parameter vegetatif, generatif, dan produksi, maka perlakuan biostimulan PPBBI pada konsentrasi lebih tinggi yakni 20 ppm tidak selalu menunjukkan pengaruh yang sangat signifikan dibandingkan dengan perlakuan pada konsentrasi yang lebih rendah, yakni 10 ppm. Hasil tersebut berkorelasi pada hasil penelitian sebelumnya bahwa aplikasi biostimulan diperlukan pada konsentrasi rendah dan dalam jumlah sedikit, seperti kandungan poliamin yang dilaporkan dapat membantu regulasi pertumbuhan dan perkembangan organ tanaman hanya pada konsentrasi micromolar, sehingga ekstrak rumput laut pada konsentrasi 1,5% menunjukkan pengaruh yang signifikan untuk menginduksi pertumbuhan dan meningkatkan hasil mutu panen tanaman, sedangkan konsentrasi yang lebih tinggi dari 1,5% dapat menunjukkan efek inhibisi pada tanaman (Michalak et al, 2017;Vijayanand et al, 2014;Jardin, 2015), khususnya pada konsentrasi tinggi biostimulan berbasis ekstrak rumput laut dapat menghambat pertumbuhan akar tanaman (Anisimov et al, 2013).…”

The Indonesian government program of achieving self-sufficiency of soybean by 2020 requires technological innovations for the farmers. The use of plant biostimulant is an innovative strategy and proven previouslyto increase the productivity of several otherfood crops. The aim of this study was to analyze the effect of PPBBI biostimulant on the growth, productivity and quality of a Wilis variety of soybean under greenhouse conditions. PPBBI biostimulant at10 ppm and 20 ppm, was applied using foliar spray method with 20 mL volume to each plant. The applications were carried out 1 time, 2 times and 3 times. Six biostimulant treatments showed significant positive effects on the vegetative growth rate, generative organ development, and yield. The biostimulant accelerated vegetative growth to enter the generative phase earlier than that of in the control plants. The period of generative organs maturity required for treated plants was 7-14 d shorter than that of in the control plants so that the harvest period was 21 d shorter. Weight per 100 seeds of the P2-3 (application 3 times at 20 ppm); P2-2 (application 2 times at 20 ppm); P2-1 (application 1 time at 20 ppm) and P1-3 (application 3 times at 10 ppm) treatments were 20.16 g; 17.65 g; 18.89 g and 16.89 g respectively with no significant difference, while the control plants was only 11.60 g. Based on the results of all parameters e.g. average number of seeds, average weight per seed, and potential for yield improvement, the treatment of P1-3 (application 3 times at 10 ppm) was the best treatment with potential yield increase by 59.06% and oil content by 11.37%.[Key words: generative, organic biostimulant, productivity, vegetative] AbstrakProgram pemerintah Indonesia dalam pencapaian swasembada kedelai pada tahun 2020 membutuhkan dukungan inovasi teknologi yang aplikatif untuk para petani. Biostimulan tanaman merupakan salah satu teknologi yang strategis dan terbukti dapat meningkatkan produktivitas beberapa tanaman pangan. Tujuan penelitian ini adalah untuk melakukan analisis pengaruh aplikasi biostimulan PPBBI terhadap partum-buhan, produktivitas dan kualitas hasil panen kedelai varietas Wilis pada kondisi rumah kaca. Biostimulan PPBBI dengan variasi konsentrasi 10 ppm dan 20 ppm, diaplikasikan pada tanaman kedelai dengan metode penyemprotan lewat daundengan volume 20 mL per tanaman.Penyemprotan dilakukan sebanyak 1 kali; 2 kali dan 3 kali aplikasi. Enam perlakuan biostimulanyang diujikan menunjukkan pengaruh positif yang signifikan pada kecepatan pertumbuhan vegetatif, stimulasi perkembangan organ generatif dan peningkatan hasil panen. Biostimulan PPBBI mempercepat laju pertumbuhan vegetatif untuk memasuki fase generatif lebih awal dibandingkan tanaman kontrol. Masa perkembangan dan pemasakan organ generatif polong pada tanaman perlakuan menjadi lebih pendek 7-14 hari dibandingkan tanaman kontrol sehingga secara keseluruhan masa panen tanaman perlakuan lebih singkat 21 hari. Bobot per 100 biji tanaman kedelai perlakuan P2-3; P2-2; P2-1 dan P1-3 berturut-turut mencapai 20,16 g; 17,65 g; 18,89 g; dan 16,89 g dengan tidak adanya perbedaan signifikan, sedangkan tanaman kontrol hanya 11,60 g. Berdasarkan hasil analisis seluruh peubah yaitu rerata jumlah biji, rerata bobot per biji, dan potensi produksi, maka perlakuan P1-3 (aplikasi tiga kali dengan dosis 10 ppm) merupakan perlakuan terbaik dengan potensi kenaikan produksi mencapai 59,06% dan kadar lemak 13,7%.
