“…The results of identification reveal that Bahari local sorghum has two panicle shapes: symmetrical (found in G2, G4, and G6 sorghum) and pyramidal (found in G1, G3, and G5 sorghum). This result agrees with the research result by Mukkun et al (2018) who characterize 53 local sorghum species in Nusa Tenggara Timur and find two panicle shapes: symmetrical and pyramidal.…”

Local sorghum (Sorghum bicolor) is a cereal crop that the people of Bahari Village, Buton Selatan Regency still cultivate as an interlude crop of corn. Local sorghum (Sorghum bicolor) functions as genetic material and a gene donor to improve the crop's characters in a plant breeding program. Therefore, it is necessary to take conservation steps to maintain the availability of sorghum germplasm collections. This study aims to characterize local sorghum (Sorghum bicolor) from Bahari Village, Buton Selatan Regency based on morphological characters (qualitative vegetative and generative parameters) and agronomic characters. This study was an explorative study that directly identified the genotypes of local Sorghum bicolor cultivated in the field. This study reveals six genotypes of local Sorghum bicolor; they are Labanda, Lapandewa, Lagadi, Wapinauri, Mbae, and Madea. The differences in sorghum genotypes can be more clearly identified in the generative phases, namely the symmetrical and pyramidal panicle shapes; the panicle density can be grouped into loose, slightly compact, and compact; husk colors vary from black, orange, grey, yellow, white, to red; the husk traits are categorized into short, slightly long, and very long; and the seeds are categorized round and round flat and white and brown. Meanwhile, the agronomic characters indicate that sorghum genotypes have long panicles; the weight of 100 seeds vary in categories from very low, low, to moderate; and one sorghum genotype (genotype Lagadi) has the fastest flowering and harvest ages than the other genotypes.

“…Examination of qualitative characters for the assessment of morphological variability referred to Descriptors for Sorghum [19], including the determination of numerical scores for the analysis of taxonomic relationships. The use of qualitative characters in this study referred to previous studies on the analysis of morphological variations of sorghum landraces [11,15,16]. The numerical taxonomic methods used to reveal the grouping of sorghum accessions were cluster analysis and principal component analysis.…”

“…Based on preliminary field observations, sorghum in Java Island exhibit morphological variability, with three commons variants were recognized namely sorghum accessions with white, red, and brown grains. Publications on sorghum diversity in Indonesia were generally come from the eastern part of the country, particularly from East Nusa Tenggara [15,16]. A research on sorghum in Java was still very limited with the aim to observe the suitability of dry land in Gunungkidul [17].…”

Sorghum bicolor (L.) Moench is a member of Poaceae family with three agronomic types corresponds to their specific uses namely grain sorghum, sweet sorghum, and forage sorghum. Although sorghum in Indonesia is considered as under-utilized crop, but it has the potential as an alternative resource for staple food in diversification program to support food security. The potential of sorghum as alternative staple food is due to its high nutritional value, and the ability to grow well in marginal lands with maintaining good productivity. The objectives of this study were to assess the extent of morphological variability and to resolve taxonomic relationship of sorghum accessions from Java Island based on morphological characters. Twenty nine sorghum samples were collected from three provinces in Java, namely Central Java, Special Province of Yogyakarta, and East Java. Morphological data observed refers to Descriptors for Sorghum, generating 19 qualitative characters used in cluster analysis and principal component analysis. Cluster analysis resulted in the grouping of 29 accessions into three groups corresponding to the racial classification of sorghum. Results of principal component analysis showed that the main distinguishing characters between groups were inflorescence compactness and shape, glume coverage, presence or absence of awn, presence or absence of grain sub-coat, grain shape, and grain color. Analysis of correlation showed that there were very strong relationship between glume coverage and the presence of awn, and between the presence of grain sub-coat and grain color. Results of this study revealed that sorghum accessions cultivated on Java Island consisted of four races namely Bicolor, Guinea, Caudatum, and Kafir.

“…Pengembangan usahatani sorgum tentu saja dipengaruhi oleh berbagai faktor dalam mencapai produksi yang diharapkan. Menurut Mukkun et al (2018) ketersediaan benih yang tidak menentu merupakan salah satu faktor permasalahan utama yang dihadapi petani pada usahatani sorgum, ditambah lagi petani sendiri belum mampu untuk menghasilkan benih yang cukup dan unggul dari usahataninya. Petani juga merasakan kurangnya pendampingan dan tingkat adopsi teknologi petani dalam pembudidayaan juga masih sangat rendah, hal ini menyebabkan kurangnya pemahaman petani dalam mengaplikasikan teknik budidaya sorgum yang tepat, masih banyak petani yang membudidayakan sorgum tanpa olah tanah dan tidak melakukan pemeliharaan tanaman yang intensif (Winarti et al, 2020).…”

It is hoped that the development of a new production center for sorghum commodities, especially in East Sumba Regency, can increase sorghum production and supply sorghum needs nationally in order to face the world food crisis. To achieve this, it is important to be able to formulate the right strategy for developing sorghum in East Sumba Regency which has dry land conditions. The aim of this research is to analyze the internal and external environment of sorghum farming in East Sumba Regency and to determine priority strategies for developing sorghum farming in East Sumba Regency. This research is a qualitative research with analytical descriptive analysis conducted in July - December 2023 in East Sumba Regency. Respondents in this research were key informants who were determined using a purposive sampling technique. Data collection was carried out by means of field observations, Focus Group Discussions (FGD) and in-depth interviews according to research problems with key informants. The analytical methods used in this research are SWOT analysis and QSPM. The results of the SWOT matrix analysis show that there are 6 alternative strategy formulations that can be applied to the development of sorghum farming in East Sumba. Meanwhile, the results of the QSPM analysis show that the first priority alternative strategy that can be applied by farmers in developing sorghum farming on dry land in East Sumba is optimizing land use to increase production.
