Pengaruh aplikasi pelapisan benih terhadap viabilitas benih terdeteriorasi serta pertumbuhan tanaman kedelai

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and soil pollution can be avoided. The study aimed to determine the effect of biofertilizers with different compositions of microorganisms on the growth of maize plants. The research was carried out in a greenhouse. Maize plants were fertilized by two kinds of biofertilizers with different compositions of microorganisms. The first biofertilizer contained Azotobacter sp, Azospirillum sp, Rhizobium sp, Trichoderma sp, and Lactobacillus sp, and the second biofertilizer contained Strenotrophomonas sp. and Paenibacillus polymyxa. As controls, maize plants were fertilized by sterilized those biofertilizers. The results showed that the second biofertilizer increased the dry weight of the maize plant. Meanwhile, the first biofertilizer did not increase it. Several things must be considered in the application of biofertilizers, such as the composition of microorganisms, type of plant, level of fertilization, and the method of applying fertilizer to the plant.

Kualitas benih akan mempengaruhi dinamika pertumbuhan tanaman. Tujuan penelitian ini adalah untuk mengkaji respons benih terdeteriorasi terhadap aplikasi berbagai pelapis benih, baik berupa insektisida maupun pelapis hayati berupa suspensi mikroorganisma yang dicerminkan dengan peningkatan laju tumbuh tanaman. Penelitian merupakan percobaan petak terbagi dua faktor, yaitu tingkat deteriorasi (D) yang terdiri dari benih berkualitas baik (DB = 84 %) dan benih terdeteriorasi (DB = 75 %) . Pelapis benih yang digunakan terdiri dari Thiametoxam, Rhizobium sp , Azotobakter sp , campuran Azotobakter sp + Rhizobium sp, dan Trichoderma sp. Hasil Percobaan menunjukkan bahwa tidak ada pengaruh interaksi antara tingkat deteriorasi benih dengan jenis pelapis benih terhadap semua parameter yang diamati. Kualitas benih memberi respons pertumbuhan yang berbeda terhadap jenis pelapis benih yang diberikan. Aplikasi pelapis benih berupa insektisida maupun inokulan mikroorganisme tidak mampu meningkatkan vigor benih yang sudah terdeteriorasi, tetapi berpengaruh terhadap jumlah nodula efektif, perkembangan klorofil, Laju Tumbuh Relatif, Laju Asimilasi Bersih , dan Nisbah Pupus Akar. Secara umum pemberian Rhizobium sp dan Azotobacter sp dapat meningkatkan jumlah nodula efektif, tetapi tidak secara nyata mempengaruhi pertumbuhan tanaman.

This study aims to examine the effect of PGPR in increasing the growth and yield of red chilies, and to find the type of PGPR that gives the best growth and yield in red chilies. The research was conducted at the Teaching and Research Farm, Faculty of Agriculture, Jambi University, 35 above sea level. The study used a randomized block design with one factor, namely various types of PGPR: without PGPR; PGPR1 (containing Trichoderma sp., Bacillus sp., Pseudomonas sp., 11 essential macro and microelements, as well as natural amino acids); PGPR 2 (containing Pseudomonas fluorescent, Trichoderma sp., Aspergillus niger, Azobacter sp., Azospirilium sp., And Rhizobium sp.); PGPR 3 (containing Trichoderma sp., Pseudomonas sp., And Rhizobium sp.); and PGPR 4 (containing Azosbacteria sp, Aspergillus niger, and Trichoderma harzianum). Each treatment was repeated five times. The results showed that the application of PGPR was able to increase plant growth and yield of red chilies in the form of plant height (2.12% - 9.69%), the total number of branches (5.25% -54.96%), number of fruits (13,55% -51.40%) and fruit weight (54.19% -116.35%). The quality of crop yields has also improved with the application of PGPR. PGPR which contains Pseudomonas fluorescent, Trichoderma sp, Aspergillus niger, Azobacter sp, Azospirilium sp, and Rhizobium sp. is PGPR that provides the best growth and yield of red chilies

Percobaan “Pengaruh Pupuk Organik Cair (POC) dan Trichoderma sp Terhadap Pertumbuhan dan Hasil Melon (Cucumis melo) telah dilaksanakan di Kelurahan Air Pacah, Kecamatan Koto Tangah di Kota Padang. Tujuan penelitian ini adalah untuk mengetahui pengaruh pupuk organik cair dan Trichoderma sp terhadap pertumbuhan dan hasil Melon (Cucumis melo). Percobaan ini menggunakan rancangan acak lengkap 2 faktor (Trichoerma sp dan POC). Trichoderma sp terdiri dari 2 tingkat yaitu 0 g L-1 dan 200 g L-1 per tanaman, sedangkan POC pemberian terdiri dari 4 tingkat yaitu 0 ml L-1, 25 ml L-1, 50 ml L-1 dan 75 ml L-1 dengan 3 ulangan dan setiap satuan percobaan 2 polibeg sehingga diperoleh 48 polibag. Dari hasil percobaan disimpulkan bahwa pemberian 200 gram inokulan Trichoderma sp dan 75 ml L-1 POC yang diberikan setiap 2 minggu mampu meningkatkan pertumbuhan dan hasil tertinggi berat buah segar mencapai 1,33 kg/buah Experiment "The Effect of Liquid Organic Fertilizer (LOF) and Trichoderma sp Against Growth and Melon Yield (Cucumis melo L) has been conducted in Air Pacah Koto Tangah Subdistrict in Padang City. The purpose of this research is to know the effect of liquid organic fertilizer and Trichoderma sp on growth and yield of Melon (Cucumis melo L). This study used a complete randomized design of 2 factors (Trichoderma sp and POC). Trichoderma sp consists of 2 levels of 0 g L-1 and 200 g L-1 per plant, whereas POC administration consists of 4 levels ie 0 ml L-1, 25 ml L-1, 50 ml L-1 and 75 ml L-1 with 3 replications and each unit of experiment 2 polybag so obtained 48 polybags. The experimental resulted that giving 200 grams of Trichoderma sp inoculum and 75 ml L-1 POC was given every 2 weeks can increase the growth and yield of melon. The highest yield of fresh fruit 1.33 kg/fruit.
