Abstract

Rice is Indonesians' main source of nourishment. Farmers get the seeds for growing their paddy crops from both non - local rice genotypes and local genotypes. The two main consideration factors influencing the decision to use the seed varieties are high production of the varieties and customer preferences. Local rice genotypes in Kuantan Singingi Regency have potential to fulfill the requirements. This study aimed to ascertain the response the regional rice genotypes in Kuantan Singingi Regency to planting system technology. The experiment was designed in Split Plot Design in a Completely Randomized Design (CRD), the main plot consisted of multiple cultivation systems (Factor S) as follows: Tile system, Jajar legowo system (2:1), and Rice Intensification systems. The following genotypes were then employed in subplots using a completely randomized design (CRD): Kuning Umur Panjang (G07), Samo Putiah (G09), Limbayang (G10), Singgam Putih (G14), Pulut Kari (G16) and Kuning (G18). The findings showed that.local rice genotypes responded differently to the planting system technology.  Limbayang genotype had  dry milled grain weight per clump of 105.57 grams, while the Singgam Putih genotype had  plant height of 141.00 cm. The rice intensification system (SRI) gave the best growth and production to Limbayang and Singgam Putih. The findings of the study can be taken into consideration for future research, such as plant breeding efforts to enhance the traits of local rice genotypes.  Keywords: rice intensification system, local rice genotype, planting system technology

Abstract

In a natural ecosystem, the plant establishes a mutual relationship with beneficial endophytes contributing huge impact on its host plant. Therefore, exploring beneficial endophytic fungi identified in a wide range of host plant species and their interaction is an interesting area of study. The present work aimed to characterize the fungal endophytic communities associated with local rice varieties. Healthy local rice variety commonly grown in Kuantan Singingi (Padi Kuning, Padi Gondok, Padi Sironda Putih, and Padi Sironda Merah) were selected and sampled. The samples were taken from different plant parts (root, stem and leaf). Descriptive statistics were used to present  the results of this study. Results obtained from the present study showed that a total of 8 isolates were found in Padi Kuning, 9 isolates in Padi Rondok, 11 isolates in Padi Sironda Putih,  and 11 isolates in Padi Sironda Merah. From different tissue parts of the plant, a total of 14, 12, and 13 isolates was found in stem, leaf, and root, respectively. Comparisons of the stem, leaf and root samples demonstrate a similarity in the endophyte assemblages among the local rice varieties and plant parts.
