Pertanian menjadi sektor penting bagi masyarakat Indonesia sebagai tumpuan pemenuhan kebutuhan pangan. Kebutuhan pangan akan selalu meningkat dengan seiring pertambahan jumlah penduduk. Berdasarkan data Badan Pusat Statistik dan Direktorat Jendral Hortikultura tahun 2018 sampai 2019, produktivitas nasional tanaman hortikultura pada beberapa jenis sayuran rata-rata negatif dan mengalami penurunan. Inovasi melalui metode smart hidroponik Internet of Thing (IoT) dan tenaga surya dapat diterapkan dalam usaha meningkatkan produktivitas tanaman dan profitabilitas produksi. Penelitian ini bertujuan meningkatkan produktivitas hasil budidaya pertanian berbasis IoT dibandingkan dengan budidaya pertanian tradisional yang dilakukan saat ini. Beberapa jenis tanaman yang tanam dalam penelitian ini adalah kangkung (Ipomea aquatica), caisim (Brassica chinensis var. parachinensis), selada keriting (Lactuca sativa), dan pakcoy (Brassica rapa subsp. chinensis). Dua perlakuan yang diberikan Budidaya   sayuran   pada   media   tanah   yang   terproteksi   oleh greenhouse dan budidaya sayuran pada media hidroponik berbasis tenaga surya yang terproteksi oleh greenhouse berteknologi 4.0. Percobaan dilakukan dengan menggunakan rancangan acak lengkap (RAL) dengan 3 ulangan. Tinggi tanaman, diameter batang, jumlah daun, panjang daun, dan bobot tanaman dengan budidaya pertanian berbasis tenaga surya yang terproteksi oleh greenhouse berteknologi 4.0 menghasilkan pertumbuhan yang lebih besar dibandingkan dengan tanaman yang ditanam di tanah.

Metabótitos secundários produzidos em algumas plantas podem provocar alterações no desenvolvimento de outras plantas ou até mesmo de outros organismos. Neste trabalho, objetivou-se identificar possíveis efeitos alelopáticos de extratos aquosos de folhas de Cyperus rotundus na germinação e no crescimento de plântulas de Brassica campestris, Brassica oleracea var. botrytis, Brassica oleracea var. capitata, Brassica oleracea var. italica, Brassica rapa, Lactuca sativa cv. Grand rapids, Lycopersicum esculentum e Raphanus sativus. Foram utilizadas sete concentrações do extrato aquoso (0, 10, 30, 50, 70, 90 e 100%). Os tratamentos foram arranjados em delineamento inteiramente casualizado, com cinco repetições de dez sementes das espécies cultivadas, constituindo a unidade amostral. Os extratos aquosos de C. rotundus evidenciaram potencialidades alelopáticas na germinação das sementes e no crescimento das duas partes vegetais (raiz e parte aérea), de todas as espécies testadas, exceto na germinação de sementes de tomate e de alface, sendo que a redução aumentou com o aumento das concentrações dos extratos aquosos utilizados. A estrutura vegetal mais afetada em presença dos extratos aquosos foi o sistema radicular das plântulas.

O objetivo do trabalho foi avaliar o efeito de diferentes espectros de luz sobre o potencial fisiológico de espécies olerícolas. O experimento foi conduzido em delineamento inteiramente casualizado, no esquema fatorial três por cinco, com quatro repetições. As três espécies testadas foram alface (Lactuca sativa L.), rúcula (Eruca sativa Mill.) e couve chinesa (Brassica rapa var. pekinensis). Os cinco espectros de luz utilizados foram: vermelho, azul, amarelo, branco e ausência de luz. O teste de germinação foi conduzido em germinador tipo BOD, com temperatura constante de 25°C. Para a alface o espectro azul revela efeito negativo sobre as variáveis primeira contagem, percentual de germinação e comprimento de radícula. Para espécies de rúcula e couve chinesa, o espectro de luz vermelha e amarela apresentaram os melhores resultados para as variáveis estudadas.

Lactuca Sativa L

Aquaponic is considered one of alternative culture system to improve production and quality of leafy vegetables by combining soil less culture and fish farming. Utilization of fish manure contained in waste water provides nutrient sources for growing plants. Three kinds of leafy vegetables including water spinach (Ipomoea aquatica F.), green coral lettuce (Lactuca sativa L.), and bok choi (Brassica rapa L.) were grown using both aquaponic and hydroponic system at the Green House in Serut village, Panti District, Jember Regency, from April to June 2019. Productions of each leafy vegetable were evaluated on both culture systems. Water spinach represented 29.12% higher production in aquaponic than hydroponic system, shown by significant value in plant height, number of leaves, root volume, and leaf fresh weight. Otherwise, bok choi production displayed 17.03% increased in hydroponic than aquaponic system. However, leaf production of lettuce was not significant between hydroponic and aquaponic system. Lettuce production in aquaponic only 1.90% lowest than hydroponic system indicated that lettuce was appropriate to cultivate in both farming systems.

The Impact

Abstract Background Seed sanitization via chemical processes removes/reduces microbes from the external surfaces of the seed and thereby could have an impact on the plants’ health or productivity. To determine the impact of seed sanitization on the plants’ microbiome and pathogen persistence, sanitized and unsanitized seeds from two leafy green crops, red Romaine lettuce (Lactuca sativa cv. ‘Outredgeous’) and mizuna mustard (Brassica rapa var. japonica) were exposed to Escherichia coli and grown in controlled environment growth chambers simulating environmental conditions aboard the International Space Station. Plants were harvested at four intervals from 7 days post-germination to maturity. The bacterial communities of leaf and root were investigated using the 16S rRNA sequencing while quantitative polymerase chain reaction (qPCR) and heterotrophic plate counts were used to reveal the persistence of E. coli. Result E. coli was detectable for longer periods of time in plants from sanitized versus unsanitized seeds and was identified in root tissue more frequently than in leaf tissue. 16S rRNA sequencing showed dynamic changes in the abundance of members of the phylum Proteobacteria, Firmicutes, and Bacteroidetes in leaf and root samples of both leafy crops. We observed minimal changes in the microbial diversity of lettuce or mizuna leaf tissue with time or between sanitized and unsanitized seeds. Beta-diversity showed that time had more of an influence on all samples versus the E. coli treatment. Conclusion Our results indicated that the seed surface sanitization, a current requirement for sending seeds to space, could influence the microbiome. Insight into the changes in the crop microbiomes could lead to healthier plants and safer food supplementation.
