Abstract

Biofertilizers are recommended to improve crops yield but researches regarding biofertilizer inoculation on foxtail millet in Indonesia is still Tlimited. The objective of the experiment was to analyze the growth and yield responses of five local-millet accessions to Bacillus biofertilizer with reduced NPK fertilizer dose; and the germination rate of millet seeds. The pot experiment was arranged in randomized block design with 10 treatments and 10 replications. The treatments were combination of five millet accessions with one dose of NPK fertilizer, and half dose of NPK fertilizer with biofertilizer. Generally, half dose of NPK with Bacillus inoculation did not change the height of six-weeks old plant, and panicle weight and length of millet compared to one dose of NPK. However, this combined fertilizer increased plant height and panicle length of Mani-Mani 79. Reduced dose NPK with Bacillus inoculation increased panicles number of J3 but reduced that of Polman 3; moreover, this combined fertilizer increased the grain weight of J3 and J4, but decreased the yield of Polman 3. The Enrekang and Polman 3 accession had better germination rate; 92% and 89.33%, respectively. This research considered that Bacillus biofertilizer reduced NPK fertilizer dose by 50% and is suggested for growing millet.ABSTRAKPupuk hayati banyak disarankan untuk meningkatkan produksi tanaman tetapi riset mengenai inokulasi pupuk hayati pada jewawut aksesi lokal Indonesia belum banyak dilakukan. Percobaan ini bertujuan untuk menganalisis respons pertumbuhan dan hasil lima aksesi jewawut lokal terhadap inokulasi pupuk hayati Bacillus dan pengurangan dosis pupuk NPK; serta daya berkecambah biji jewawut setelah panen. Percobaan pot disusun dalam rancangan acak kelompok dengan 10 perlakuan dan 10 ulangan. Perlakuan percobaan adalah kombinasi lima aksesi jewawut dengan satu dosis pupuk NPK, dan setengah dosis pupuk NPK disertai pupuk hayati. Umumnya, tinggi tanaman umur enam minggu, serta bobot dan panjang malai jewawut dengan setengah dosis NPK disertai inokulasi Bacillus sama dengan tanaman yang diberi satu dosis NPK. Namun, tinggi tanaman dan panjang malai Mani-Mani 79 meningkat setelah aplikasi setengah dosis NPK dengan inokulasi Bacillus. Jumlah malai aksesi J3 meningkat sedangkan Polman 3 menurun dengan aplikasi setengah dosis NPK disertai inokulasi Bacillus. Kombinasi pupuk ini meningkatkan bobot biji J3 dan J4 tetapi  menurunkan hasil Polman 3. Aksesi Enrekang dan Polman 3 memiliki daya berkecambah yang lebih baik; masing-masing sebesar 92% dan 89,33%. Penelitian ini menunjukkan bahwa pupuk hayati Bacillus dapat mengurangi dosis pupuk NPK sampai 50% dan dapat disarakan untuk tanaman jewawut.

Abstract

Tatsoi is a popular vegetable in the community but has not been widely cultivated in South Sumatra. Compost tea is a type of liquid organic fertilizer that is easy to make and can increase plant growth and production. This study aimed to determine the best combination of source and type of compost to increase the tatsoi growth and yield. The research was conducted on May-August 2023 at the Experimental Garden of Faculty of Agriculture, Sriwijaya University. The research consisted of 2 factors designed in a Randomized Complete Factorial Design. The first factor was the source of compost, namely cow manure, chicken manure, goat manure, vermicompost, and oil palm empty fruit bunch compost. The second factor was the type of compost: solid compost, aerated compost tea 1:5 (b/v), aerated compost tea 1:10 (b/v), non-aerated compost tea 1:5 (b/v), and non-aerated compost tea 1:10 (b/v). Based on the research, the application of various types and sources of compost interacted significantly on the growth and yield of tatsoi, except on the number of leaves and root crown ratio variables. The combination of aerated chicken manure compost tea treatment with a ratio of 1:5 (b:v) was the best treatment in the cultivation of tatsoi in soil of lebak swamp.ABSTRAKSawi pagoda merupakan salah satu sayuran yang populer di masyarakat namun belum banyak dibudidayakan di Sumatera Selatan. Teh kompos adalah jenis pupuk organik cair yang mudah dibuat serta mampu meningkatkan pertumbuhan dan hasil tanaman. Penelitian ini bertujuan untuk mengetahui kombinasi terbaik sumber dan jenis kompos untuk meningkatkan pertumbuhan dan produksi sawi pagoda. Penelitian dilaksanakan pada bulan Mei-Agustus 2023 di Kebun Percobaan FP Universitas Sriwijaya. Penelitian terdiri dari dua faktor dalan Rancangan Acak Lengkap Faktorial (RALF). Faktor pertama adalah sumber kompos yaitu pupuk kandang sapi, pupuk kandang ayam, pupuk kandang kambing, vermikompos, dan kompos tandan kosong kelapa sawit. Faktor kedua adalah jenis kompos yaitu: kompos padat, teh kompos aerasi perbandingan 1:5 (b/v), teh kompos aerasi perbandingan 1:10 (b/v), teh kompos tanpa aerasi perbandingan 1:5 (b/v), dan teh kompos tanpa aerasi perbandingan 1:10 (b/v). Berdasarkan hasil penelitian, aplikasi berbagai jenis dan sumber kompos berinteraksi secara nyata terhadap pertumbuhan dan hasil sawi pagoda, kecuali pada peubah jumlah daun dan nisbah tajuk akar. Kombinasi perlakuan teh kompos kotoran ayam yang diaerasi dengan perbandingan 1:5 (b:v) merupakan perlakuan terbaik dalam budidaya tanaman sawi pagoda pada tanah asal rawa lebak.

Abstract

The phenomenon of climate change has an impact on agricultural sector, including the cultivation of shallots. To meet the needs of the community, an approach is taken through the application of biofertilizers and the use of shallot varieties that are resistant to off-season cultivation. The research aimed to determine the optimal concentration of biofertilizer and the resilient shallot varieties for the off-season cultivation. This research was conducted in February–May 2023 in Ngringo Village, Jaten District, Karanganyar, Central Java, with an altitude of 189 masl. This study used a Split Plot Design method. Shallot Variety was the main plot, namely: Bima Brebes, Maja Cipanas, and Bali Karet. Biofertilizer concentration was the subplots, i.e : 0, 3, 6, 9, 12 ml l-1 per plot, resulting in 15 treatment combinations with three replications. Observation parameters included leaf area index, net assimilation rate, plant growth rate, bulb diameter, and bulb fresh weight. The results indicated that biofertilizers did not affect the growth of shallots. Regarding yield quality, a concentration of 12 ml l-1 per plot could increase bulb diameter and bulb fresh weight. The Bali Karet variety generated better bulb diameter and bulb fresh weight, and it is capable of adapting when planted off-season.ABSTRAKFenomena perubahan iklim berpengaruh pada sektor pertanian, termasuk budidaya bawang merah.

Abstract

Dendrobium is a genus of orchid that has the most attraction among the public rather than other types, especially for orchid species such as Dendrobium nindii type. The obstacle in cultivating orchids species is the slow vegetative growth when compared to orchids resulting from crosses (hybrid orchids). This research aimed to determine the vegetative growth of D. nindii seedlings using Rhizoctonia sp. The research was conducted at the Greenhouse, Faculty of Agriculture, Tunas Pembangunan University from January to July 2023. The research used quantitative descriptive method consisting of one treatment with six replications and each replications contained ten plants. The factor was application of Rhizoctonia mycorrhiza and without application of Rhizoctonia mycorrhiza. The results showed that (1) the morphological characteristics of Rhizoctonia mycorrhiza were white colonies, with right-angled branches and two nuclei, (2) the application of mycorrhizal Rhizoctonia had a very significant effect on the vegetative growth of D. nindii as shown in the parameters of plant height, leaf length, number of leaves, root length, number of roots and fresh weight of seedlings, and (3) there was an association of Rhizoctonia mycorrhiza with the formation of the peloton structure.ABSTRAKDendrobium merupakan salah satu genus anggrek yang memiliki daya tarik paling banyak di masyarakat diantara jenis anggrek lainnya terutama untuk anggrek spesies seperti Dendrobium nindii. Kendala dalam budidaya anggrek spesies adalah pertumbuhan vegetatif yang lambat bila dibandingkan dengan anggrek hasil persilangan (anggrek hibrida). Penelitian ini bertujuan untuk mengetahui pertumbuhan vegetatif bibit D. nindii dengan menggunakan Rhizoctonia sp. Penelitian dilakukan di Rumahkasa Fakultas Pertanian Unversitas Tunas Pembangunan dari Januari sampai Juli 2023.
