“…The success of soilless cultivation lies in the use of planting media that can provide ideal root conditions to support plant growth and development [13]. Biological, physical, and chemical conditions of the media will affect the growth and development of plant roots which then affect plant production [14].…”

The agricultural sector faces two serious threats: declining production due to agricultural land conversion and water shortages due to global warming. Therefore, an agricultural system that accommodates the use of vacant land and water saving, in this case, urban farming with the use of soil-less media can be applied. In recent studies, both innovations have shown positive results in various commodities but have not been explored much specifically for rice crops. This study observed the effect of soilless media application (mixed water and rice husks media) on the growth of rice. This experiment was conducted in Sumber Jeruk, Jember (altitude 281 m asl, temperature 21-31°C, RH 65-75%), January-June 2022. The experiment used a completely randomized design with two factors and three replications. The first factor was the ratio of water to rice husk (1:0; 4:1; and 8:1). The second factor was rice varieties (Inpari 46, IR 64, and Mapan 05). The combination of Mapan 05 and media ratio 4:1 showed the highest result on shoot fresh weight (351.95 g) and root fresh weight (346.35 g). Meanwhile, the highest number of root length (45.20 cm) was found in the combination of Mapan 05 and media ratio 8:1. Moreover, Mapan 05 (93.94 cm) and Inpari 46 (93.88 cm) showed no significant difference in plant height. It can be concluded that soil-less media 8;1 promotes the highest result on rice plant growth observed.

“…Changes in the rhizosphere microbial community structure over time have been well documented and could be attributed to both changes in the environmental conditions and the influence of the plant development stage [33][34][35]37]. For root-influenced bulk soil, the importance of plant exudates was found to be low compared to changes in soil properties [93]. The change in bulk soil microbial community composition between the sampling dates found in this study is thus likely mainly due to changes in environmental conditions like soil water content and temperature and is less affected by plant development.…”

Phosphorous (P) starter fertilization can increase maize (Zea mays L.) yield. Widespread application in soils with sufficient P availability leads to environmental risks. Subsequently, alternative strategies to support the maize plant’s early development are needed to lower P surpluses. Here, we conducted field experiments comparing standard starter fertilizer diammonium phosphate (DAP) (20.1 kg P ha−1) to microgranular fertilizer (MG) (2.4 kg P ha−1) and combined in-furrow inoculation with Bacillus atrophaeus and mycorrhizal fungi (Rhizoglomus irregulare, Funneliformis mosseae, and Funneliformis caledonium), alone and in combination. The soil microbial community inside and between the maize rows was monitored by quantitative PCR (qPCR)-based quantification of eight fungal and bacterial groups. The yield did not vary between fertilization with DAP or MG and no fertilizer control. The combined microorganism inoculum (MO), however, enhanced the yield by 4.2%. The soil microbial community composition was not affected by the MO application. However, on one field site and inside the rows, it leads to a significant increase in overall microbial gene copy numbers by 9.3% and a significant decrease in the relative abundance of the bacterial phylum of Bacillota (Firmicutes) by 18%. The in-furrow MO application is thus a promising option for starter fertilizer replacement.
