Abstract

Demand for rice as a source of food continues to rise, while the capacity to produce a rice paddy more limited. One effort is to develop upland rice tolerance to drought and high production potential. The study was conducted at the Experimental Faculty of Agriculture Unhalu. Character judgments production were observed between (1) the number of tillers at harvest, (2) the number of productive tillers, (3) panicle length (cm), (4) the number of filled grain/panicle  and  seed  weight  of  100  grains.  The  results  showed  that  there  are  two varieties that are very resistant to drought conditions, namely Bali and Wangkariri Sala. While five local upland rice varieties are very sensitive to drought are varieties Paebiu Sitoro, Wagamba, Paebiu Angata, Apolo, Wakawondu. Keywords: drought resistance, drought stress, upland rice.

Abstract

Rice is an important food crop in the world, exceeding potatoes, corn, wheat and other cereals. The experiment was conducted to study differences in the  growth characters of some progenies from the crosses of upland rice and to know the cross combinations which produced the best growth characters. The research treatment was seven progenies from crosses of upland rice.   Seven progenies of the rice grown in the field experiment were evaluated based on morphological characters, especially rice stems and leaves. Based on the stem color and the color of the sheath, there were two groups consisted of F2 plants population of progeny A (33/Wagamba (1)), E (Wagamba/33), and F (33/Wagamba (3)) with the color purple midrib purple stem and base. In the second group contained of the F2 plant population of progeny B ( 33/Wagamba (2)), C (Cegelius/Wangkoito (1)), D (Cegelius/Wangkoito (2)), and G (33/Wagamba (4)) with the base of the stem and sheath color were green. The progeny A (33/Wagamba (1)) and progeny E (Wagamba/33) were the best progeny because it had several advantages such as growth form upright, erect leafs, plant height, number of tillers, and dark green leaves. Keywords: growth character, crosses, upland rice, progeny, selection.

Abstract

The  research was  conducted to  test  the  potency  of  several local  maize genotypes (landraces) of Southeast Sulawesi and to find the genotypes that were tolerant to less water conditions. The research was performed in  a  plastic house at  the  experimental farm of Agriculture Faculty, University of Halu Oleo.  The research was arranged in a Randomized Complete Design (RCD) with 2 treatment factors. The first factor was water availability level (A), consisted of 3 (three) levels (A0, A1 dan A2), and the second factor was maize genotype, consisted of 9 local maize and 1 national variety (Arjuna).  Research results showed that the less water conditions (A1 and A2) had negative effects on maize vegetative variables (plant height, plant diameter, leaf number and length of leaf tip).  On the other hand, the genotype treatment had significant effect on plant height, plant diameter, and length of leaf tip. Genotipe G7 dan G6 had the highest plant height, while G1 had the biggest plant diameter. Keywords: less water condition, local maize genotype, vegetative stage

Abstract

Efforts to increase rice production to achieve sustainable production faced a serious challenge. Rice demand is increasing due to population growth, changing consumption patterns of non-rice to rice, and the improvement of the local economy. On the other hand the national rice production is more limited. One alternative way to secure national rice production is through development of sub-optimal land, in the form of dry land, for upland rice cultivation. Potency of dry land for upland rice is big enough though constrained by such factors of soil fertility, rainfall and the presence of blast attacks. Test for drought stress was conducted using the Standard Evaluation System (SES) for Rice developed by the International Rice Researh Institute (IRRI). The results of the study on 24 local upland rice cultivars, based on the degrees of curl leaf and shoot dry index, it was known that there were two varieties that are very resistant to drought stress, i.e. cultivar Sala Bali and cultivar Wangkariri, and as many as six cultivars i.e. Paebiu Kolopua, Paebiu Tamalaki, Wangko'ito, and Wa Mengkale that were resistant to drought. Keyword: drought resistant, germplasm, upland rice

Abstract

The study aimed to determine the optimal composition of planting material to enhance the growth of porang seedlings. The study was conducted in the laboratory of the Agronomy Department, Agriculture Faculty of Halu Oleo University, Kendari, and continued in field nursery at Wua-Wua District, Kendari City, Southeast Sulawesi. This research was carried out in two stages: (1) testing at the germination stage in the laboratory and (2) testing at the seedling stage in a field experiment. Kendari City, Southeast Sulawesi, from October to December 2021. Testing at the germination stage in the laboratory used a completely randomized design consisting of six treatments of planting media compositions, namely M0 (soil), M1 (soil + rice husk charcoal; 1;1), M2 (soil + rice husk charcoal + organic fertilizer; 1:2:1), M3 (soil + rice husk charcoal + organic fertilizer; 1:1:2), M4 (soil + rice husk charcoal + organic fertilizer; 1:2:2), M5 (soil + rice husk charcoal + organic fertilizer; 1:2:3). While the test at the nursery stage used a randomized block design, with the same treatments as the treatments at the germination stage. The findings indicated that the composition of planting media significantly affected the growth of porang seedlings. The optimal planting media composition for enhancing the growth of porang seedlings consisted of soil, rice husk charcoal, and organic fertilizer in a ratio of 1:2:3. The increase in plant growth, as indicated by stem diameter, was 133% relative to the control group.

Abstract

Indonesia has great potential for traditional medicinal plants which have been used for generations to maintain health. However, the utilization of home yards as productive land for Family Medicinal Plants (TOGA) is not yet optimal in many areas, including Konda Satu Village, South Konawe Regency. In fact, TOGA can be a source of herbal ingredients that function as a preventive and promotive effort to boost the body's immune system. Therefore, the activity of Socialization and Utilization of Village Land for TOGA Planting was carried out in Konda Satu Village. This activity aimed to increase community knowledge about the benefits and cultivation methods of TOGA, while simultaneously optimizing village land that was not yet productive. The implementation was carried out through counseling and direct practice of planting TOGA, such as turmeric, lemongrass, bitter leaf (sambiloto), and galangal on village land. This activity received a positive response and successfully fostered community awareness and self-reliance in utilizing local natural resources for herbal-based health

Abstract

[EVALUATION OF SUPERIOR RICE GENOTYPES (Oryza sativa L.) BASED ON VEGETATIVE CHARACTERISTICS TO ENHANCE FOOD SECURITY]. This study aimed to identify superior genotypes of upland rice (Oryza sativa L.) adaptable to dryland conditions to support national food security. The experiment was conducted in Kambu Subdistrict, Southeast Sulawesi, using a Randomized Complete Block Design (RCBD) with four replications. Eight genotypes were evaluated for five vegetative parameters—plant height, number of leaves, number of tillers, leaf area, and days to flowering measured at 21-77 days after planting (DAP). Significant genetic variation was observed among genotypes. Genotypes GS11-2, GS44-1, and GS16-1 exhibited superior early growth,with plant heights of 58-60 cm at 35 DAP, significantly outperforming the local control (41.6 cm). Correlation analysis revealed a strong positive relationship between plant height and leaf area (r=0.94 at 49-77 DAP) and a significant negative correlation between plant height and number of tillers (r=-0.86). Coefficients of variation ranged from 8.5-19.5%, indicating reliable data, except for leaf area at 21 DAP (30.1%). These findings underscore the value of early selection based on vegetative traits, particularly plant height and leaf area, as reliable indicators of yield potential. Genotypes with rapid and stable vegetative growth hold promise for development as dryland-adapted varieties. This research provides a robust scientific foundation for upland rice breeding programs to address land conversion and climate change challenges, thereby enhancing national food resilience.
