“…The positive regression was highly significant, between the area of the flag leaf and the number of filled grain/panicle with the weight of the filled grain/panicle. A similar report was reported in a previous study [23,24]. It is indicating that these two characters were the determinants of the weight of the grain/clump.…”

The information on rice genetic material is needed to create new high-yielding varieties adaptive to dryland. Local rice genetic resources have been tested to be tolerant under conditions affected by global climate change (increased temperature, pest/disease attacks, droughts). This study aims to identify and characterize the agronomic character of local rice in Musi Rawas (MURA) and North MURA Regencies, South Sumatra. The results of identification and characterization, as well as correlation and regression analysis, revealed that three local varieties have agronomic characteristics that determine high-yield local rice productivity. This information can be utilized by breeders to create new superior varieties of rice in dryland. The agronomic characteristics of three local rice varieties that determine productivity are the area of the flag leaf and the number of filled grain/panicles. Local varieties with superior agronomic characteristics are Siam, Bolouh, and Gel. These three varieties have the potential to be used as parents in the creation of new high-yielding varieties that are specific, namely having broad flag leaves and a high number of filled grains/panicles. The acquisition of new high-yielding varieties specific to dryland through a breeding program will increase the choice of varieties for stakeholders and support increased rice production in dryland.

“…The rice productivity in rainfed land varies seasonally. In the dry season with limited irrigation rice productivity is only 3.20 t/ha [8] and in the rainy season ranges between 3.2 to 4.50 t ha -1 [8,9,10].…”

Rice is a staple food for the Indonesian people and is a national strategic commodity for national food security. Rainfed area is a potential land to support national rice production, by improving soil management through balanced fertilization based on the soil characteristics. This study aims to determine the soil fertility and alternative management implemented in 2019 and 2020 in Sukaraja and Pondok Kelapa sub districts, Bengkulu Province. Soil fertility status for CEC, base saturation, C-organic, total P and total K taken based on the classification of the value of the combination of these chemical properties. The results showed that the soil fertility status of the rainfed rice fields in Sukaraja and Pondok Kelapa sub districts was low. The limiting factors for soil fertility for Sukaraja sub district are alkaline saturation, total K-total and P-total for Pondok Kelapa sub district. The limiting factors are all elements related to nutrient status assessment, namely CEC, base saturation, total P, total K and C-organic. Alternative soil management is carried out in an integrated manner by providing balanced organic and inorganic fertilizers. The provision of soil amendments such as straw compost, manure, biochar and agricultural lime/dolomite, especially for acid reacting soils, aims at increasing soil fertility before fertilization is applied.
