Abstract

Mung bean plant is one of the most popular sources of plant-based protein as a daily food ingredient. In Indonesia, mung beans are one of the most important legume commodities after soybeans and peanuts. The objective of this research is to determine the effect of inorganic fertilizer dosage and weeding time, as well as the interaction between inorganic fertilizer and weeding time, on the growth and yield of mung bean plants. This research was conducted in Libungo Village, Suwawa Selatan Subdistrict, Bone Bolango Regency, and observations of destructive variables were carried out at the Agrotechnology Department Laboratory, Faculty of Agriculture, Universitas Negeri Gorontalo. The factorial RBD design was used, consisting of two factors. The first factor was the application of inorganic fertilizer, with two levels (150 kg/ha and 300 kg/ha), and the second factor was weeding time, with three levels (no weeding, weeding at 7 and 14 days after sowing, and weeding at 7, 14, and 21 days after sowing). The results showed that the application of inorganic fertilizer, weeding time, and the interaction between inorganic fertilizer and weeding time did not have a significant effect on all parameters, including leaf area, leaf area index, plant growth rate, flowering percentage, pod number, weight of 100 seeds, and yield per plot.  Keywords: Mung Bean, Inorganic NPK Fertilizer, Weeding Time

Abstract

This study aimed to determine the role of water hyacinth (Eichhornia crassipes Mart.) organic matter on water retention at pF 2.54 and pF 4.2, available water content, and bulk density (BD). The research method used was a factorial randomized block design. The first factor was the sorghum variety, which consisted of 2 levels, namely, V1 (variety) and V2 (Kawali). The second factor was the dose of water hyacinth organic matter, which consisted of 5 levels, namely P0 (without the application of water hyacinth organic matter), P1 (10 tons.ha-1), P2 (20 tons.ha-1), P3 (30 tons.ha-1), and P4 (40 tons.ha-1). Water retention was measured at pF 2.54 and pF 4.2 using a pressure plate apparatus and pressure membrane apparatus, respectively, and BD was measured using the ring method. The results showed that the treatment of organic matter application and varieties had a significant effect on water retention at pF 2.54, available water content, and BD with the best treatment of 40 tons of organic matter application and Kawali variety, but not affecting water retention at pF 4.2. There was no interaction between water hyacinth organic matter and sorghum varieties to improve water retention and BD. The highest water retention at pF 2.54 was 32.24% (P4), and the highest available water content was 11.67% (P4) but not significantly different from P3 (11.55%); the lowest BD was 1.11 g.cm-3 (P4) but not significantly different from P3 (1.13 g.cm-3). A very strong positive linear and negative linear correlation exists between available water content and BD with plant height, panicle length, and sorghum yield.

Abstract

Tanaman sawi (Brassica juncea L.) merupakan sayuran daun bernilai ekonomi tinggi yang banyak dibudidayakan, namun produktivitasnya masih dipengaruhi oleh kondisi kesuburan media tanam. Penggunaan bahan organik seperti pupuk kandang sapi dan arang sekam berpotensi memperbaiki sifat fisik dan kimia media serta meningkatkan ketersediaan unsur hara. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi media tanam pupuk kandang sapi dan arang sekam terhadap pertumbuhan dan hasil tanaman sawi. Penelitian dilaksanakan di screenhouse BRMP Provinsi Gorontalo pada bulan Oktober–November 2025 menggunakan Rancangan Acak Kelompok dengan lima perlakuan, yaitu P0 (100% tanah), P1 (65% tanah + 25% pupuk kandang sapi + 10% arang sekam), P2 (50% tanah + 30% pupuk kandang sapi + 20% arang sekam), P3 (40% tanah + 30% pupuk kandang sapi + 30% arang sekam), dan P4 (20% tanah + 40% pupuk kandang sapi + 40% arang sekam), masing-masing diulang tiga kali. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, luas daun, berat segar tanaman, dan berat akar. Hasil penelitian menunjukkan bahwa kombinasi media tanam berpengaruh nyata terhadap pertumbuhan dan hasil tanaman sawi. Perlakuan P2 memberikan hasil terbaik dengan tinggi tanaman 31,17 cm, luas daun 122,19 cm², serta berat segar tanaman tertinggi dibandingkan perlakuan lainnya. Kombinasi pupuk kandang sapi dan arang sekam pada komposisi seimbang mampu memperbaiki kondisi media tanam dan mendukung pertumbuhan serta hasil tanaman sawi secara optimal. Mustard greens (Brassica juncea L.) are a high-economic-value leafy vegetable widely cultivated in Indonesia; however, their productivity is strongly influenced by growing media fertility. The application of organic materials such as cattle manure and rice husk charcoal has the potential to improve the physical and chemical properties of the growing media and enhance nutrient availability. This study aimed to determine the effect of combinations of cattle manure and rice husk charcoal on the growth and yield of mustard plants. The research was conducted in the screenhouse of BRMP Gorontalo Province from October to November 2025 using a Randomized Block Design with five treatments: P0 (100% soil), P1 (65% soil + 25% cattle manure + 10% rice husk charcoal), P2 (50% soil + 30% cattle manure + 20% rice husk charcoal), P3 (40% soil + 30% cattle manure + 30% rice husk charcoal), and P4 (20% soil + 40% cattle manure + 40% rice husk charcoal), each replicated three times. Observed parameters included plant height, number of leaves, leaf area, fresh weight, and root weight. The results showed that the combination of growing media significantly affected the growth and yield of mustard plants. Treatment P2 produced the best results with a plant height of 31.17 cm, leaf area of 122.19 cm², and the highest fresh weight compared to other treatments. A balanced combination of cattle manure and rice husk charcoal improved media conditions and supported optimal growth and yield of mustard plants
