“…The variety of plant heights between varieties is caused by genetic factors and environmental factors. This is inline with the opinion of [12] which state that plant height is a genetic factor that characterizes the plant itself and is influenced by local environmental conditions.Plants that grow well are able to absorb nutrients in large quantities, so that in a growing environment with sufficient nutrient availability, it has an effect on increasing plant photosynthetic activity. Plant N uptake was positively correlated with root length, surface area, volume, and biomass so that plant growth and yield components increased [14].…”

“…Plant height and number of tillers are among the selection criteria for rice plants, but high growth does not guarantee a high level of productivity. [12], stated that plant height is influenced by plant genetic traits, growing environmental conditions, and their interactions in the environment where it grows. The difference in genetic makeup is one of the factors that cause differences in plant growth.…”

“…The weight of 1000 gains of Winongo was also significantly different from IR 64. Yields were determined by yield components, while yield components were determined by plant genetics and environmental factors (climate, nutrients/soil, and water) [12]. Plant growth components affect plant yield components.…”

High yield varieties with pests and disease resistance and environmental stress is one of the important technological components for increasing farmer productivity and income.. This research was conducted in irrigated rice fields in Kebakramat District, Karanganyar Regency at planting season (PS) II (March-July) and PS III (July-November). The purpose of this study was to determine the growth performance and productivity of high-yield varieties of rice. The completely randomized design was used with 3 treatments 5 times repeated. Code, Winongo were used and IR 64 as a comparison. Phonska 300 kg/ha and Urea 250 kg/ha were used in this study. Data of plant height, number of tillers, panicle length, and production were collected. Data plant growth and grain yield were analyzed using variance analysis. The results showed that high-yield varieties affected increasing production. The highest rice productivity obtained from the Code reached 8.44 t / ha DMG at PS 3 or 18.2% higher than the existing IR 64, while Winongo reached 8.05 t/ha DMG or 12.7% higher from IR 64. Code has the highest production, however, Winongo at PS 3 can also be used as a choice as a substitute for IR 64 besides Code in Karanganyar Regency.

“…The water requirement of upland rice across the whole life cycle is only 20% of that of paddy rice (Zhang et al, 2020). On the other hand, upland rice shows higher tolerance to biotic and abiotic stresses than paddy rice (Narenoot et al, 2017; Phapumma et al, 2020). Although upland rice has many advantages, upland rice exhibits abnormal endosperm development and causes a sharp decrease in yield, and poor rice quality has become a problem for traditional upland rice (Fageria et al, 1982; Cavite et al, 2020).…”

Varieties of local upland rices which have adapted to agro-ecological conditions are mostly cultivated by small-scale farmers [3]. They are also planted through the sweeden system on poor soils [4], however, low biotic and high abiotic stresses greatly contribute to the decrease in productivity [5].…”

Seaweed extract is known to contain nutrients and growth-regulating substances that affect soil biota, and a source of protection against pests and diseases. Earthworm, which is an example of a soil biota and playing the role of ecosystem engineer, has the ability to produce suitable land biostructures, for the inhabitation of arbuscular mycorrhizal fungi (AMF), which has an impact on upland rice growth. Therefore, this study aims to determine, (i) the effect of seaweed extract on the population of earthworms and spores of arbuscular mycorrhizal fungi, and (ii) the impact of the engineered soil on the growth of local upland rice varieties. Furthermore, the extract of seaweed, such as Kappapychus alvarezii, was divided into five concentration levels, namely 0%, 20%, 40%, 60%, and 80%. Each treatment was drenched into the soil from the cogongrass vegetated area, mixed with 20 Pheretima sp., and maintained for 49 days in the greenhouse. The result showed that the total difference in the earthworms’ concentration treatments was not significant. It also showed that the total AMF spores in the engineered soil products of 20% concentration was the highest. Based on treatment with the earthworm engineered soil products, the highest and lowest vegetative growth and yield components of upland rice were observed at the concentrations of 80% and 0%, respectively. In conclusion, the application of seaweed extract to the soil did not significantly reduce the earthworm population. The extract concentration of 20% also increased the total AMF spore in the engineered soil. Moreover, highly treated engineered soil products increased the growth and yield components of upland Kambowa rice on cogongrass soils.
