Abstract

Produksi kedelai di Indonesia hingga saat ini belum mampu mencukupi kebutuhan masyarakat Indonesia. Rerata kebutuhan kedelai secara nasional mencapai 3,4-3,6 juta ton pertahun, sedangkan produksinya hanya 20%-30% dari kebutuhan tersebut. Berdasarkan hal tersebut perlu adanya upaya untuk meningkatkan produksi tanaman kedelai yaitu dengan cara pemberian POC keong mas. Penelitian ini bertujuan untuk mengkaji pengaruh pemberian kombinasi pupuk anorganik dan POC keong mas terhadap pertumbuhan dan hasil tanaman kedelai. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Non faktorial yang terdiri atas 7 perlakuan yaitu tanpa POC (100% pupuk anorganik), konsentrasi POC 250 ml/l +50% anorganik, 300 ml/l+50% anorganik, 350 ml/l +50% anorganik, 400 ml/l +50% anorganik, 450 ml/l+50% anorganik dan 500 ml /l+50% anorganik. Sebanyak 4 kali ulangan. Hasil penelitian menunjukkan bahwa konsentrasi POC 500 ml/l+50% anorganik menunjukkan hasil tertinggi pada tinggi tanaman, jumah cabang produktif, berat biomassa tanaman kedelai, jumlah polong persampel, berat segar polong persampel, berat kering polong persampel dan berat kering biji persampel.

Abstract

The use of AB mix as a nutrient in soilless rice cultivation actually prolongs the vegetative phase which results in late flowering and suboptimal grain filling. This study aims to examine the effect of ABC Mix (AB Mix + silica) and gibberellin nutrients on flowering age, growth, and yield of red rice in a soilless cultivation system. This experiment was designed using a split plot design, where ABC mix nutrients were the main plot while gibberellins were the subplots and replicated three times. The concentration of ABC Mix nutrients consisted of 4 levels, namely 750-800 ppm, 1000-1050 ppm, 1250-1300 ppm, and 1500-1550 ppm, while the concentration of gibberellins consisted of 2 levels, namely 0 ppm (control) and 200 ppm. The results showed that there was a significant interaction between the ABC Mix 750-800 ppm and GA3 200 ppm treatments on plant height (192.0 cm). The single treatment of GA3 200 ppm showed a significant effect on plant height (192.0 cm), while the ABC Mix treatment of 750-800 ppm showed a significant effect on the total number of tillers (60.03 stems), the number of productive tillers (23.03 stems), panicle length (55.42 cm), and plant height (192.0 cm). However, the addition of silica to the AB Mix (ABC Mix) and the applied GA3 was not able to accelerate the flowering phase, where the flowering time was still above 80 days after planting. This was suspected to be due to the inappropriate timing of GA3 application, while the activation of the flower meristem gene takes about 5 days after GA3 application. The inaccuracy in the timing of GA3 application actually resulted in the growth of gigas plants (twice as much as normal plants) and a low number of productive tillers (±38% of the total number of tillers).

Abstract

Limited P availability in the soil is caused by the low solubility and absorption of P components, particularly in soils with low organic matter content. The purpose of this study is to investigate how phosphate fertilizer and cow dung fertilizer affect the yields of edamame crops. Between July and October of 2024, this study was carried out in Kaliurang Village, Jember, which is 146 meters above sea level and has an average temperature of 24 to 32 degrees Celsius (8o09'29.2"S 113o44'21.0"E). A Factorial RAK with two factors and three replications was used to design this experiment. There were three levels of phosphate fertilizer treatments: 1.7 g/plant, 2 g/plant, and 2.3 g/plant. Three levels of cow dung fertilizer treatment are available: 2 kg/plot, 4 kg/plot, and 6 kg/plot. Variables of observation, namely 2 kg/plot, 4 kg/plot, and 6 kg/plot. Observation variables included plant height, number of fertile nodes, number of pods per sample, pod weight per sample, and dry biomass weight. The results showed that the treatment interaction of 2,3 g phosphate fertilizer/plant and 6 kg cow dung fertilizer/plot had a significantly different effect in the dry biomass weight variable per sample (18,13 g). This is suspected to increase the availability of P in the root media, as the absorption of P by organic fertilizers also increases. Treatment of 2,3 g/plant of phosphate fertilizer had a significantly different effect on pod weight per sample (50,70 g). This is suspected to increase the availability of P in the root media, as the absorption of P by organic fertilizers also increases.

Abstract

Seedlings produced through tissue culture with an imbalanced ratio of growth regulators often exhibit poor quality and uneven growth. The success of shoot multiplication in granola potato can be improved by optimizing the ratio of growth regulators, particularly auxins and cytokinins. This study aimed to determine the optimal concentrations of Indole-3-acetic acid (IAA) and kinetin for shoot multiplication of granola potato. The experiment was conducted from June to October 2024 at the Tissue Culture Laboratory of Jember State Polytechnic. A Completely Randomized Factorial Design (RALF) was used, consisting of two factors and three replications. The first factor was IAA concentration, comprising 0.4 mg L⁻¹, 0.7 mg L⁻¹, and 1.0 mg L⁻¹. The second factor was kinetin concentration, consisting of 0.5 mg L⁻¹, 1.0 mg L⁻¹, and 1.5 mg L⁻¹. The results showed a significant interaction between 0.4 mg L⁻¹ IAA and 0.5 mg L⁻¹ kinetin in accelerating callus emergence, with the earliest appearance observed at 6.33 days. This indicates that a balanced ratio of auxin and cytokinin can promote faster callus development. The combination of 0.7 mg L⁻¹ IAA and 1.0 mg L⁻¹ kinetin resulted in the earliest shoot emergence at 5.67 days. This is likely because IAA promotes cell elongation, while kinetin stimulates cell division. Treatment with 1.0 mg L⁻¹ IAA showed a highly significant effect on the number of segments (24.89) and the number of roots (29.22). Meanwhile, treatment with 0.7 mg L⁻¹ IAA significantly increased root length (5.91 cm). These results suggest that IAA plays a vital role in promoting cell elongation and enhancing cell wall plasticity, enabling cells to expand and elongate more effectively.

Abstract

Rice (Oryza sativa L.) play an important role as a major food source to meet the needs of densely populated communities. The use of superior varieties and planting at the right distance can significantly increase production, thereby supporting optimal growth and maximum yields. This study was conducted from July to October 2023. This research was arranged in a factorial randomized block design (RBD), involving two factors: the first factor included dense planting distances, namely 40 cm × 25 cm × 25 cm, 30 cm × 25 cm × 25 cm, and 20 cm × 25 cm × 25 cm; while the second factor was rice varieties, namely Ciherang and Situbagendit. The analysis of the results showed that the interaction between planting distance and variety did not have a significant effect on the various parameters measured. However, the 30 cm × 25 cm × 25 cm planting distance produced superior performance in most growth and production indicators, such as plant height reaching 92.31 cm, number of tillers 22.64, number of panicles 16.72, and grain weight per plot 413.50 g. The Situbagendit variety also stood out with optimal results compared to Ciherang, as seen in plant height of 94.95 cm, dry weight of 67.88 g, and weight of 1,000 grains of 278.46 g. The absence of significant interaction indicates that the effect of planting distance is more due to competition between individual plants, while variety differences are more dependent on genetic characteristics. Therefore, the combination of a 30 cm × 25 cm × 25 cm planting distance with the Situbagendit variety is recommended as the optimal choice for increasing rice plant productivity.
