Soybean Adaptation to Water Stress on Vegetative and Generative Phases
Get PDFSoybean is rich in protein and is one of the main sources of vegetable protein which essential in enhancing public nutrition. Climate change is the main trigger of the occurance of extreme weather events makes plants become more vulnerable to drought. Drought stress significantly affect the decline in soybean production, especially when it occurs during the reproductive phase. This research aimed to identify the response of soybean to water stress as a reference for determining the adaptive and tolerant varieties. The research was arranged in split-split plot design, with main plot was varieties (Dering and Argomulyo), the development phase (vegetative and  generative phases) as the subplot, and water stress in the form of irrigation intervals (2, 5, and 10 days) as the sub-sub plots. The results showed that water stress during the vegetative phase has not statistically significant effect on soybean production. Soybean crop adapted  to water stress by reducing the number of leaves, the leaf area, stomatal openings, as well as doing motion response by folding leaves. This crop adaptation mechanisms affecting the formation of dry matter quantity, seeds yield, water use efficiency, and radiation use efficienc

AGRONOMIC CHARACTERS OF WHEAT (TRITICUM AESTIVUM L.) GROWN USING TWO CROPPING SYSTEMS IN MEDIUM LAND OF PALOPO CITY
No full textWheat (Triticum aestivum L.) is a staple food for most of world population and has a good prospect considering the great potential of land to be planted with this plant species which contains carbohydrate of 70% and protein of 3%. The development of this commodity was started from agricultural extensification and production increase through the implementation of cropping system. This study was aimed to provide information on suitable cropping system for wheat cultivation and to examine the effect of cropping system on the increase in wheat production in medium land of Palopo City. This study was conducted in farmer land in Kambo Village, Mungkajang Subdistrict of Palopo City, South Sulawesi at elevation of ± 600 m asl from June until September 2017. This research uses two factor factorial in randomized block design. The first factor consisted of two cropping systems, namely line up system (S1) and Hazton system (S2). While, the second factor included two varieties, namely Guri 4 variety (V1) and Guri 6 variety (V2). Study result for vegetative phase showed that the best plant height was obtained using line up cropping system in Guri 4 variety (S1V1) with average of 73.91 cm. Implementation of Hazton cropping system in Guri 4 variety (S2V1) resulted in the best flag leaf area with average of 40.23 cm2. Hazton cropping system implementation in Guri 6 variety (V2S2) indicated the best green color with average value of 11.00 unit. Furthermore, application of line up cropping system (S1) produced the best total tiller number with average of 18.22 tillers. Therefore, it is concluded that the use of Hazton cropping system was able to increase the wheat production and Guri 4 Variety is expected to adapt to grow in the medium land of Palopo Cit
The Role of Customary Leaders on the Decision Making Process in the Ethics of Land Clearing and Harvesting Process in Rice Farmers in Puday Village, Wonggeduku Barat Sub-District, Konawe District
Get PDFCustomary leaders have dominant roles and influences, these facts are shown in the land clearing process (monahundau) and the harvesting process (meolu) of paddy rice crop. These processes begin with the opening ceremony or in the form of a small ritual carried out by customary leader numbering one person called Puusaraormandaranosara. The purpose of this study is to find out how the role of customary leaders in decision-making in the ethics of land clearing and harvesting processes in paddy rice farmers. Analysis of the data used in the form of qualitative descriptive analysis, where the data obtained is then described qualitatively using the Miles and Huberman model which consists of three stages, namely (1) Data Reduction, (2) Data Presentation, (3) Conclusion Drawing / Verification. The results of this study indicated that land clearing (monahundau) and the harvesting process (meolu) were influenced by hereditary customs in Puday Village, Wonggeduku Barat Sub-District, Konawe District. Monahundau is a land clearing process which is the first step to open a new planting season every year. Meoluis a harvesting process that is carried out in the same steps as the process of land clearing (observation, reciting intentions and praying silently for the best wishes desired in the harvesting process), and the final step is done by investigating at the rice fields who first turned yellow (ripe), then the rice fields that will be harvested first, the rice begins to be harvested when there is already a statement then the other farmers' land that has yellowed (ripe) may be harvested by themselves (meoludowo). Customary leaders are people chosen by the people of Puday village (puusaraormandaranosara) and have an influnce on decision making in the process of land clearing (monahundau) andharvesting (meolu
GENETIC CHARACTERIZATION OF GALOBA DURIAN (AMONUM SPP.) IN AMBON ISLAND BASED ON RANDOM AMPLIFIED POLYMORPHIC DNA (RAPD)
Get PDFGaloba durian is one of the endemic floras from Maluku. Galoba durian is a species belonging to the Amomum genera Zingiberaceae family. It is also used as a medicinal plant for waist and kidney diseases. Based on the color of the fruit, galoba durian is divided into two nmely red galoba durian and green galoba durian. Distribution of this plant in Ambon can found in a few places such as highland and coastal area. Different locations influence phenotypic of plants, but may not show different genetic characteristic. Genetic diversity can detected by molecular markers. Genetic characterization from galoba durian using RAPD markers has not been done before. This study aimed to analyze genetic diversity from galoba durian using molecular markers RAPD. Samples of plants are used red galoba durian from Hatu and green galoba durian from Hatalae. The result of the first study, characterization of the morphology of the galoba durian, showed that both galoba have almost similar characteristics. Further DNA was tested by qualitative and quantitative. Result shows good qualitative and quantitative of DNA genomic. The second study was amplification by PCR-RAPD. DNA amplifications were performed using 3 primers out of 9 screened random primers. The primers selection was based on hight polymorphism. DNA amplification has 36 bands which were 100% polymorphic. The size of each bands from visualization of agarose was determined by linear regression. Number of band amplified was range from 120 to 1612 bp. Polymorphic band of RAPD showed the highest genetic diversity. It can be concluded that the two plants of galoba durian are different specie
