Abstract

The soaring level of public consumption and the decrease in the area of ​​cultivated land forced farmers to innovate. One of the efforts to increase healthy food production is to utilize functional rice with soilless cultivation methods. This study aimed to examine the best water and husk ratio in soilless cultivation of two functional rice varieties. This study used a completely randomized factorial design (RALF) with 2 factors and 3 replications. The first factor was water and husk soilless media with a ratio of 6:1, 8:1, 10:1, 12:1, and 14:1, while the second factor was the Watu dodol A3 and Merah A2 varieties. The results showed that the 8:1 soilless water and husk media gave the highest performance on the number of panicle grains (231,5 grains) and the number of rice panicle grains (205,67 grains). In addition, there were significant differences in plant height, productive tillers, and panicle length between Watu dodol A3 and Merah A2.

Abstract

Soil microorganism activity is inhibited during the dry season, especially in dry land. Mulching is one of the efforts to maintain soil moisture and microorganism activity. This study aims to examine the growth response plant edamame against the use of mulch straw and application PGPR (Plant Growth Promoting Rhizobacteria). Conducted from July to September 2024 in Kaliurang Village, Jember with an altitude of 146 meters above sea level. This experiment was designed using factorial RAK consisting of two factors and three replications. Factor First that is concentration PGPR Which consists of from 0 ml/l (control), 12.5 ml/l and 25 ml/l, while the second factor is the thickness of straw mulch consisting of 2.5 cm, 4.5 cm, And 6.5 cm. Results study This show existence interaction from PGPR And mulch straw on treatment mulch 6.5 cm + 12.5 ml/l with tall 17.30 cm 24 HST. In the treatment (4.5 cm + PGPR 12.5 ml/l) it influenced the height plant age 32 HST (23.00 cm), amount pod per sample 20.13 pod and biomass dry18.53 g, whereas amount branch per sample on treatment (0 ml/l + 6.5 cm) 1.93 branches. However, the weight of pods per sample and the weight of pods per plot did not happen interaction. Heavy pod per sample on concentration 25 ml/l (55.02 g), at a mulch thickness of 4.5 cm (54.31 g). Pod weight per plot 1255.89 g (25 ml/l) and 1253.22 (4.5 cm). Use mulch straw allegedly capable guard humidity soil so that the microorganisms in PGPR are able to grow well and activity microorganisms in a way can directly influence growth and edamame crop yields.

Abstract

Climate change impacts on maize cause a decrease in yields, changes in phenology, heat stress, water scarcity, and vulnerability to pests and diseases. Enhancing agricultural resilience to climate change highly recommended using intercropping between maize and edamame. This research aims to determine the suitability of climatic factors for maize and edamame in different patterns (monoculture of maize; intercropping of maize and edamame; intercropping with basil; and intercropping with lemongrass). This research was conducted from June to September 2024 in the Kebonsari field, Jember. The results show that climate factors affect maize and edamame soybean plants, particularly soil temperature and humidity, which have an influence of more than 50%.

Abstract

National soybean productivity tends to decline each year due to land degradation caused by excessive use of synthetic fertilizers. This dependence can be reduced by applying humic acid and vermicompost. This research aims to examine the effect of humic acid and vermicompost on soybean growth and yield. The research was conducted from August to November 2024 at the Jember State Polytechnic research site, using a factorial Randomized Block Design (RAK) with two factors and three replications. The first factor is the dosage of humic acid (10, 20, 25, and 30 kg/ha), and the second factor is the dosage of vermicompost (15 and 20 tons/ha). Data were analyzed using ANOVA, followed by the DMRT test at a 5% or 1% level. The research results showed that the combination of 25 kg/ha humic acid and 20 tons/ha vermicompost significantly affected the number of root nodules (7.17 pieces). Separately, the application of 20 kg/ha humic acid significantly affected the fresh pod weight per sample (2.02 g) and the fresh pod weight per plot (124.89 g). Vermicompost at 20 tons/ha also had a significant effect on plant height (26.69 cm). These findings indicate that humic acid and vermicompost have the potential to improve soil fertility and nutrient availability for soybean plants.

Abstract

Grain filling is not ideal when AB Mix is used as a rice fertilizer in a soilless culture method because it causes a lengthy vegetative phase and a brief generative phase. The purpose of this study is to investigate the use of ABC Mix (AB Mix + Silica) to two functional rice varieties: Black Madrass and A2 Variety. A factorial Completely Randomized Design (CRD) including two factors and three replications, was used on the experimental design. The ABC Mix nutritional content (750-800 ppm, 1000-1050 ppm, 1250-1300 ppm, and 1500-1550 ppm) is the first factor, while the type of functional rice (black rice variety Black Madras and red rice variety A2) is the second. The results showed that the use of ABC mix 1000-1050 ppm on A2 red rice had a significant effect on the number of productive tillers (29.67 stems). The application of 1500-1550 ppm ABC mix showed a significant effect on the weight of 1000 grains (27.55 g), while the A2 red rice variety showed better performance based on plant height (86.64 cm). The silica content in ABC mix nutrients plays a role in strengthening plant tissue and increasing the efficiency of nutrient absorption so that it is directly able to increase the growth and yield of rice in the soilless culture system.
