“…Rakian et al evaluated the effects of using talc, bentonit, kaolin, and ground burnt rice husk as carriers on the shelf life of two DRB, Bacillus lentus A05 and P. aeruginosa A08. They demonstrated that talc, bentonit, kaolin, and ground burned-rice husk were effective carriers for both bacteria, supporting populations of B. lentus A05 and P. aeruginosa A08 for up to 20 weeks and maintaining the stability of the two DRB’s biocontrol efficacy against A. conyzoides [ 172 ]. The inclusion of semolina flour in the formulation increased the effectiveness of P. fluorescens G2-11 in inhibiting the germination of seeds and the root growth of S. viridis [ 88 ].…”

Weeds cause significant yield losses in crop production and influence the health of animals and humans, with some exotic weeds even leading to ecological crises. Weed control mainly relies on the application of chemical herbicides, but their adverse influences on the environment and food safety are a significant concern. Much effort has been put into using microbes as bioherbicides for weed control. As plant-associated bacteria (PAB), they are widely present in the rhizophere, inside crops or weeds, or as pathogens of weeds. Many species of PAB inhibit the seed germination and growth of weeds through the production of phytotoxic metabolites, auxins, hydrogen cyanide, etc. The performance of PAB herbicides is influenced by environmental factors, formulation type, surfactants, additives, application methods, and cropping measures, etc. These factors might explain the inconsistencies between field performance and in vitro screening results, but this remains to be clarified. Successful bioherbicides must be specific to the target weeds or the coinciding weeds. Detailed studies, regarding factors such as the formulation, application techniques, and combination with cultivation measures, should be carried out to maximize the performance of PAB-based bioherbicides.

“…Gulma mampu tumbuh dan berkembang pada semua jenis tanah dan pada lahan optimal maupun marginal. Hasil menurun akibat gulma karena tanaman berkompetisi dalam memanfaatan sumber daya di lingkungan tumbuh yang sama (Rakian et al 2018). Penurunan hasil padi secara nasional akibat gangguan gulma berkisar dari 6 sampai 87% (Utami & Purdyaningrum 2012), bergantung pada sistem pengendalian yang diterapkan.…”

Rice yield and proper weed control need to be increased through an environmentally friendly agricultural system approach in rainfed land during the dry season by reducing the dosage of synthetic fertilizers. This study aims to determine the effect of different fertilizer applications on rice yield and weed abundance in rainfed land during the dry season. The study used a split-plot design, with the main plot of rice variety, i.e., Situ Bagendit and IR-64, and subplots of fertilizer, namely synthetic fertilizers (N, P, K), organic fertilizers + P60 + ½ dose of synthetic fertilizers, organic fertilizers + PGPR + ½ dose of synthetic fertilizer and organic fertilizer + P60 + PGPR + ½ dose of synthetic fertilizer with three replications. The variables observed were rice yield components, namely panicle length, total empty grain and content per panicle, grain weights per hill, effective plot and hectare, 1000 grain weight, harvest index, and weeds summed dominance ratio (SDR). The synthetic fertilizers and three various organic fertilizers, biological fertilizers, and synthetic fertilizers gave different results on the SDR of weeds. The weeds of Sphenoclea zeynalica and Cyperus difformis showed consistent dominance with higher SDR than other weeds, i.e.,> 15 and > 10, respectively. The application of organic and biological fertilizers with half the recommended dosage of the synthetic fertilizers is equivalent to applying the recommended dosage of synthetic fertilizers on rice yield during the dry season on the rainfed dryland with low rainfall intensity and a low yield of 1.3–1.7 t/ha. Keywords: biological fertilizer, inorganic fertilizer, organic fertilizers, rice, weeds

“…Handayani et al (2019), juga telah membuktikan bahwa kombinasi matriconditioning dengan rizobakteri dapat meningkatkan pertumbuhan tanaman Sorgum. Selain itu juga keberadaan matriconditioning berperan sebagai media pembawa bakteri (Rakian et al, 2018) sehingga mampu mengefektifkan kinerja bakteri (agens hayati) untuk meningkatkan pertumbuhan dan hasil tanaman.…”

Penggunaan true seed untuk produksi umbi bibit ataupun umbi konsumsi belum banyak dilakukan oleh petani bawang merah di Indonesia. Penyebabnya antara lain ketersediaan true seed masih terbatas dan belum ditemukannya teknologi pembibitan dan pembudidayaan bawang merah dari true seed yang efisien. Penelitian ini bertujuan untuk menganalisis efektivitas perlakuan biomatriconditioning pada true seed pratanam yang diintegrasikan dengan aplikasi pestisida nabati terhadap pertumbuhan dan hasil bawang merah. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial dengan faktor pertama yaitu agens hayati terdiri dari 4 taraf yakni tanpa perlakuan invigorasi (B0), arang sekam + Bacillus CKD061 (B1), arang sekam + Pseudomonas SWRII B02 (B2), arang sekam + Pseudomonas W2R06 (B3) dan faktor kedua yaitu aplikasi pestisida nabati terdiri atas 3 taraf yakni tanpa aplikasi pestisida nabati (P0), 4 kali aplikasi pestisida nabati (P1) dan 2 kali aplikasi pestisida nabati (P2). Variabel yang diamati adalah tinggi tanaman, jumlah daun, diameter batang, jumlah anakan, luas daun, laju asimilasi bersih, diameter umbi, berat segar umbi dan kesehatan tanaman. Data pengamatan dianalisis ragam dan data analisis yang menunjukkan pengaruh nyata atau sangat, dilanjutkan dengan uji jarak berganda duncan pada taraf nyata α = 0,05. Hasil penelitian menunjukkan bahwa secara mandiri perlakuan biomatriconditioning benih berpengaruh terhadap semua peubah yang diamati, sementara perlakuan aplikasi pestisida nabati hanya berpengaruh terhadap peubah jumlah daun, diameter batang, luas daun dan laju asimilasi bersih. Interaksi perlakuan biomatriconditioning benih dan aplikasi pestisida nabati berpengaruh terhadap tinggi tanaman, luas daun dan laju asimilasi bersih. Perlakuan terbaik diperoleh pada biomatriconditioning benih menggunakan isolat Bacillus CKD061 yang diintegrasikan dengan aplikasi pestisida nabati 2 kali (10 HST dan 30 HST).Kata kunci: Aplikasi pestisida nabati, Biomatriconditioning, true seed Kata kunci: Aplikasi pestisida nabati, Biomatriconditioning, true seed
