"Genetic erosion in traditional rice agro-ecosystems in Southern Philippines: drivers and consequences." Plant Genetic Resources: Characterization and Utilization 18, no. 1 (January 10, 2020): 1–10. http://dx.doi.org/10.1017/s1479262119000406.

AbstractThis paper examines genetic erosion in rice landraces thriving in traditional smallholder agricultural systems in the Sarangani uplands, Philippines. In these marginal areas, the crop is closely interwoven with tribal culture and is vital in ensuring food security among upland households. Field visits unveiled high varietal diversity for upland rice and a rich tapestry of indigenous knowledge associated with its cultivation and use. Study results, however, revealed the tapering of the crop's genetic base due to farmers' changing priorities, pest infestation, weakening seed supply systems, shift to cash crops, natural calamities, environmental degradation, government programmes and peace and order problems. Consequently, these pressures undermined traditional agricultural systems in Sarangani upland communities causing food and water scarcity, hunger and suffering on a catastrophic scale. Interdisciplinary strategies aimed at simultaneously averting further varietal losses and environmental degradation while improving human well-being are therefore warranted. Furthermore, making traditional rice farming a lucrative endeavour will induce the younger generation to remain in the uplands and choose farming as a profession. This way, biocultural restoration of agriculture will be attained and the continued presence of the tribal groups in the Sarangani uplands will be ensured for a very long time.

The rainfed upland ecosystem, although often overlooked, plays a crucial role in sustaining India's impoverished population with its limited resources. This ecosystem spans across most states in the country, covering approximately 7 million hectares, with Eastern India having the highest coverage (>90%). In the typical upland ecosystem, rice is cultivated using direct seeding, employing minimal inputs such as fertilizers, insecticides, fungicides and herbicides. Upland rice farming is widely recognized for its crucial role in sustaining subsistence agriculture, catering to the nutritional needs of rainfed farming communities during the period of scarcity, particularly towards the end of September. Among all rice ecosystems, the upland environment stands out as the most diverse. Upland rice is cultivated through various methods, including permanent cultivation, block rotations, slash-and-burn (Jhum cultivation) and is established through broadcasting, seeding behind plough, or drilling seeds in small holes. It is grown both as a single crop and in combination with other cereals, oilseeds, or pulses. In specific regions like eastern Uttar Pradesh and West Bengal, short-duration upland rice is grown under transplanted conditions. The harvest from upland rice not only serves as a crucial food source for impoverished farmers but also fulfills the feed requirements for cattle during times of scarcity. The majority of upland rice cultivation is concentrated in the Eastern Plateau and Hills Region, emphasizing subsistence farming. Addressing such challenges is crucial for maximizing the potential of upland rice cultivation and its role in sustaining rainfed agriculture in India.

Abstract The research aims is to determine the suitability of nitrogen fixing bacteria, namely Actinomycetes, Azospirillum and Azotobacter with upland rice seeds to the speed of radicle formation and growth of upland rice plants. Upland rice plant growth measurement parameters include; speed of formation of radicle length, upland rice plant height, number of upland rice tillers, dry weight of the top of upland rice plants and roots of upland rice plants, wet weight of upland rice plants and roots of upland rice plants, and total N of upland rice plants and upland roots Testing the application of N2 fixing bacteria on upland rice plants on a laboratory scale was carried out to determine the suitability of microbes with upland rice plant seeds in vitro. The pot test was carried out to determine the suitability of the N2 fixing bacteria with the vegetative growth of upland rice plants in vivo. Data were analyzed using ANOVA with Duncan’s advanced test. The results showed that upland rice plants inoculated with Actinomycetes, Azospirillum and Azotobacter showed significantly different growth from upland rice plants without nitrogen fixing bacteria treatment, namely the radicle formation speed and radicle length, plant height, number of tillers, wet weight, dry weight, and total N (%) plants. It can be concluded that the inoculation of nitrogen-fixing bacteria on upland rice plants has a significant effect on plant vegetative growth parameters and plant nitrogen content.

Full textAbstract:
Shanlan upland rice (Oryza sativa L.) is a unique upland rice variety cultivated by the Li nationality for a long time, which has good drought resistance and high utilization value in drought resistance breeding. To explore the origin of Shanlan upland rice and its genetic relationship with upland rice from other geographical sources, 214 upland rice cultivars from Southeast Asia and five provinces (regions) in southern China were used to study genetic diversity by using SSR markers. Twelve SSR primers were screened and 164 alleles (Na) were detected, with the minimum number of alleles being 8 and the maximum number of alleles being 23, with an average of 13.667. The analysis of genetic diversity and analysis of molecular variance (AMOVA) showed that the differences among the materials mainly came from the individuals of upland rice. The results of gene flow and genetic differentiation revealed the relationship between the upland rice populations, and Hainan Shanlan upland rice presumably originated from upland rice in Guangdong province, and some of them were genetically differentiated from Hunan upland rice. It can be indirectly proved that the Li nationality in Hainan is a descendant of the ancient Baiyue ethnic group, which provides circumstantial evidence for the migration history of the Li nationality in Hainan, and also provides basic data for the advanced protection of Shanlan upland rice, and the innovative utilization of germplasm resources.

Continuous seasonal drought in past 3 years greatly affects rice production of Yunnan, China. Because upland rice has stronger performance than paddy rice for mountain farming, to develop mechanized production of upland rice is more beneficial to ensure food security of mountainous area. In this study, we investigate and survey traditional upland rice cultivation of peasant household in mountainous rural area of Lancang county, and use Cobb-Douglas production function to analyze the relationship between mechanized and non-mechanized upland rice cultivation. The results show that mechanized upland rice cultivation not only can increase the yield, but also is superior to non-mechanized system in techno-economics. Rational utilizing farm machinery is feasible to upland rice cultivation and will promote the development of the rice production of Yunnan Province.

Full textAbstract:
Evaluation of rice for resistance to rice blast disease caused by Pyricularia grisea usually is conducted in upland (nonflooded) disease nurseries, although all commercial U.S. rice is produced under flood irrigation. Upland rice is more susceptible to leaf blast than is flooded rice, and the magnitude of this differential susceptibility can vary among cultivars. This 2-year study was undertaken to determine (i) the relationship between rates of disease development (slow-blasting) in upland and flooded rice and (ii) the value to a rice breeding program of establishing a flooded blast nursery, a facility far more difficult to manage than an upland nursery. Among 200 rice lines compared for leaf blast susceptibility under upland and flooded cultures, only 7 were rated as slightly more resistant under upland culture and 136 rated more resistant under flooded culture. Disease ratings under upland and flooded cultures were highly correlated (R = 0.819). Among 14 preselected cultivars over 2 years, disease development curves under upland and flooded cultures were highly correlated (R = 0.990). The cultivars with intermediate susceptibility under upland culture appeared to benefit most from flooded culture. Upland culture provided more opportunities to assess slow-blasting than did flooded culture, since many lines that produced susceptible-type lesions in upland culture failed to do so under flooded culture. It was concluded that adequate information on comparative leaf blast resistance among rice lines was attainable from upland blast nurseries and that routine evaluation of rice breeding lines for blast resistance in flooded nurseries was not necessary.

Full textAbstract:
The intermittent and widespread occurrence of drought in rainfed upland rice fields across sub-Sahara Africa has led to tremendous decrease in food security in the region. Although high yielding, drought tolerant varieties have been developed over years to mitigate this trend, limited adoption had been recorded for most of these materials. This study investigated farmers’ perceptions on drought stress and their preferred traits in new upland rice varieties across two major upland rice growing states in Nigeria. Participatory Rural Appraisal was conducted among 119 rice farmers using comparative approach, probing and semi structured interviews. Result based on farmers knowledge of changes in rainfall pattern and preferred traits such as plant architecture and grain shapes in a new upland rice variety differed significantly across the two state. The results identified drought stress as one of the main constraints to upland rice production across communities. The ideal upland rice variety desired by most respondents in both states should be of medium plant height (115-130cm) characterized by white, long and bold grains. This study has demonstrated the importance of understanding farmer’s desired traits in a new upland rice variety and the need to incorporate identified traits in creation of resilient new upland rice varieties adaptable to rain-fed upland rice growing regions of Nigeria.

Upland rice has high potential development that causes the potential of dry land in Indonesia is quite large. However, the productivity of upland rice and its contribution to national paddy production is still low. Upland rice mostly is cultivated based on rainfall so productivity of upland rice depends on fluctuation of rainfall at the area. Theoretically, Indonesia has three different rainfall types, namely; equatorial, monsoonal, and local. This study aimed to identify the effect of rainfall on upland rice production. This study used secondary data consisted of upland rice yield, precipitation, and harvested area in 1990–2017. Data were analyzed by quadratic nonlinear regression and then It was analyzed by Mann-Whitney different test. Selected location were North Sumatera Province, West Kalimantan, Central Sulawesi, East Java, South Sulawesi, South Kalimantan, and Maluku. Results show that three rainfall area types statistically differences. Precipitation at Equatorial area influences upland rice yield by 3.15 tons. Furthermore, precipitation at monsoon and local area have effects on reducing production by -0.17 ton and -10.66 ton respectively.

Coastal land located in the lowlands near the coast has a marginal Entisol soil type. Entisols have the following characteristics: loose soil aggregate, sensitive to erosion, and low levels of nutrients, organic matter, water holding capacity, and soil fertility. The nature of this Entisol is less able to produce maximum upland rice production. The technology used to overcome this problem is by applying macro and micro fertilizers to the soil, which is planted with upland rice seeds, inoculated with biological fertilizers so that it is hoped that upland rice production can be maximized. The purpose of this study was to obtain high upland rice production in coastal areas. The research was carried out from June to December 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City. The research location is located at coordinates S 03?45'23'' E 102?15'41''. The experimental design used was Completely Randomized Block Design (CRBD) with 2 factors, namely types of fertilizers and varieties of upland rice. The first factor consists of P0 = No fertilizer; P1 = compound micro fertilizer; P2 = Fertilizer recommended for upland rice from the Institute for Agricultural Research and Technology). The second factor consists of V1 = red upland rice; V2 = white upland rice) The results showed that there was an interaction between the type of fertilizer and upland rice varieties on soil pH (KCl 1:2.5 w/v). the interaction of microfertilizers with white upland rice varieties resulted in the highest soil pH (5.06). The best type of fertilizer is micro-compound fertilizer which produces soil pH (KCl 1:2.5 w/v), P nutrient uptake, the highest root colonization and the highest number of production tillers and the highest grain weight per plant and upland rice yield per plot. The best upland rice variety was the white variety which produced the highest uptake of P nutrients, the number of productive tillers, the weight of grain per plant and the highest yield per plot.

Abstract Weeds can reduce rice yields by 20-89%, mainly due to competition for nutrients, water, sunlight, and growing space. Weeds that grow in rice fields come from propagules previously in the soil. Seedlings are formed from the previous season, so the cultivation system greatly affects them. This study aims to determine the diversity and population of weed propagules in upland rice and lowland rice. This research was conducted by survey method in Semanu District, Gunungkidul Regency, Special Region of Yogyakarta, by taking soil samples from three plots of upland rice and lowland rice paddy. Soil sampling was conducted four times before tillage, 3, 6, and 9 weeks after planting. The results showed that the diversity of weed propagules in upland rice was higher than in lowland rice fields with more weed propagule species. Annual terrestrial weed propagules dominate in upland rice, while in lowland rice fields, it is dominated by annual aquatic weed propagules. The diversity index of weed propagules in upland rice and rice paddy is included in the medium criteria. The number of species and individual propagule weeds in upland rice is more than in the upland rice fields. The results of this study can be used as a basis for proper weed management so that it does not disturb and harm rice plants.

The upland rice-based cropping pattern is a form of double cropping or crop rotation in which upland rice as a basic commodity (base crop) which can be preceded or alternated with other food crops as a secondary crop. This study was conducted on dry land agro-ecosystems in the Tanimbar Islands Regency (West Southeast Maluku), from March to December 2017. This study was an adaptive research with a field experiment approach in farmer's land. The objective of this research was to obtain the most profitable cropping patterns, efficiency in land use and economically also has the highest net profit so it is appropriate to be recommended as a technology innovation for upland rice-based cropping patterns in dry land. The results showed that upland rice which was cultivated in multiple ways through intercropping or overlapped cropping, namely Introduced Cropping Pattern 1 (Upland Rice + Maize-Peanuts) and Introduced Cropping Pattern 2 (Upland Rice + Corn/Cassava-Green Beans-Peanuts) can increase land productivity (index planting of 222% and 288%, respectively) and farmers' income increased by 244-588% compared to upland rice grown in monoculture. Multiple cropping patterns can be recommended as a technology package for upland rice-based cropping patterns on dry land because of its efficiency in the use of production costs and land use. Furthermore, it gave the highest farm income of IDR63,933,100,-/ha/year with a net profit of IDR45,716,380,-/ha/year or IDR15,238,793,-/ha/ cropping season.

Exploring the potential of social capital as a social strength of society in developing farming becomes the central point of sustainable agricultural development. The Arfak tribe, a farming community, living in the Papua region, has only been introduced to the introduction of upland rice in their farming activities for approximately three years. The study to find the social capital strength of the Arfak Tribe in upland rice farming, the application of upland rice farming, and the relationship between social capital and the application of upland rice farming is the aim of this research. The research was conducted in Guentuy Village, a center for upland rice production from indigenous Papuan farmers. The number of respondents was 84 Arfak Tribe farmers who cultivate field rice. The survey method uses in-depth interviews and field observations of 84 farmers from the Arfak Tribe. Data were analyzed using descriptive statistical analysis and inferential statistics. The results showed that the social capital owned by the Arfak Tribe in upland rice farming included trust in family members, transmigration farmers, and village officials to cooperate, share experiences, work without pay, and provide village funds for upland rice farming. Social interaction between family members, transmigration farmers, and village officials in discussing field rice problems, borrowing equipment from each other, and collaborating is the social capital of the Arfak Tribe’s built-in social networks. The social capital of the Arfak Tribe is in the form of obedience to find sources of consumption, not forbidding farmers to consume rice. Therefore, it gives the Arfak Tribe an opportunity to learn upland rice farming. The study results concluded that the Arfak Tribe had not fully implemented the farming component. The test results show that the social network between members of farmer groups and village officials influences the Arfak Tribe’s belief in implementing field rice farming. Furthermore, the social norms of the Arfak Tribe, which do not prohibit farmers from consuming rice, provide opportunities for Arfak Tribe farmers to learn the seed preparation stage as the initial stage of implementing upland rice farming.

"Moisture Stress in Upland Rice (Oryza sativa L.) and Measures to Overcome It under Changing Climate: A Review." International Journal of Environment and Climate Change 13, no. 10 (August 16, 2023): 337–47. http://dx.doi.org/10.9734/ijecc/2023/v13i102646.
Full textAbstract:
Low yields in upland rice (Oryza sativa L.) are frequently linked to poor crop management practices along with a lack of high yielding varieties, abiotic and biotic stressors. Drought (lack of water), overwatering (waterlogging/flooding), extreme temperatures (cold, frost, and heat), etc, all negatively impact crop and other plant growth, development, yield, and seed quality. Drought or moisture stress is the most important factor affecting upland rice under changing climate. Global climate change also exacerbates the vulnerability of upland rice production. Upland rice plants undergo physiological and biochemical alterations as well as morphological changes as a result of moisture stress. Different moisture stress affects the yield of upland rice ranging from 18-97% yield loss. As a result, crop management with broad, integrative and multi-disciplinary methodologies is required to increase productivity and profitability. Different mitigation strategies to overcome moisture stress and increase upland rice yields have been addressed in this review.

Heavy metal pollution is an important issue that must receive serious attention from various authorities, including the community. Cadmium (Cd) contamination will harm environmental and human health. Upland rice plants are the main food-producing plants susceptible to Cd contamination. This study aimed to determine the effect of vermicompost on cadmium content and the vegetative phase of upland rice plants in Inceptisol. This study used a Completely Randomized Design (CRD) with one factor, namely several dose levels of vermicompost, namely 0, 5, 10, 15, 20, and 25 t ha-1. The results of this study indicated that the use of vermicompost significantly affected the number of leaves and tillers of upland rice. A Vermicompost dose of 15 t ha-1 is considered optimum in increasing the number of leaves and tillers of upland rice. The use of vermicompost increased the vegetative growth of upland rice, so it increased the productivity of upland rice plants.

Lowland and upland rice are the two most important rice ecotypes and are grown under different ecosystems of contrasting soil water conditions. The study aimed to characterize root morphological, anatomical, and architectural traits and shoot physiological traits related to agronomic traits in Myanmar lowland and upland rice under drought conditions. Drought experiments were conducted in the field and in the greenhouse. The reduction in root traits under drought was observed in both lowland and upland rice except for the stele and xylem area. Stele area and xylem area were increased under drought in lowland rice while stele area in upland rice was decreased and was not changed in the xylem area. A positive relationship between agronomic traits and root traits of lowland rice was observed including the total number of nodal roots, root number per tiller, and a negative relationship in lateral root density more than anatomical traits. While upland rice illustrated the relationship between root anatomical traits and agronomic traits. In addition, a negative contribution to biomass by photosynthesis rate, stomatal conductance, and transpiration rate was observed in lowland and upland rice. These findings can help improve drought tolerance in rice by selecting the optimal root trait for each rice ecosystem.

Local upland rice (Oryza sativa L.) is a type of cereal crop that has the potential for dry land areas. Farmers in Kupang plant upland rice/local rice that has been consumed and used for generations and is considered by the surrounding community as part of their ancestral heritage. The materials used in this research were local upland rice varieties as a result of exploration. The varieties of six local upland rice of Kupang studied in this research had different rice characters in terms of its weight, volume, density and yield.'Aen Molo' has the highest weight per grain and per 1000 grains, namely 0.024 g and 24.95 g, also the highest volume of 1000 grains of rice is 30 ml, while 'Aen Lekes' has the lowest weight per grain and per 1000 grains, namely 0.020 g and 19.66 g and also the lowest volume of 1000 grains, namely 23 ml. The Iodine test results showed that the local rice of Kupang was classified in the regular or non-glutinous rice group. Meanwhile, Alkali test results show that the six samples of local upland rice have a high gelatinization temperature which indicates that local upland rice in Kupang Regency has high amylose content.

Brown rice (Oryza sativa) is a highly nutritious staple food that contains anthocyanins in addition to carbohydrates, fat, protein, fiber, and minerals. Anthocyanins serve as antioxidants, playing a crucial role in plant and human health. Efforts to improve rice production, particularly upland rice production, are always coupled with efforts to increase production of brown rice. The majority of brown rice is produced from upland rice. There has been no effort to manufacture brown rice before today. Therefore, efforts to expand upland rice production with native cultivars are inextricably linked to efforts to boost upland rice output of red rice. Upland rice is brown rice consumed without going through a grinding process or the process of removing the bran and bran from the endosperm of the rice. Rice is only ground into broken rice so that the husk is still attached to the endosperm and has high nutritional value. Strong body immunity and excellent health levels are needed. One of them is by consuming healthy food that is available locally and has become a daily food menu, it only needs to increase production and processing efforts so that it is always healthy. Upland brown rice can be planted as an intercrop to maximize land use for plantation crops, so it has the potential to be developed in Southeast Sulawesi because there is still a lot of unused land or land that has not been used optimally. Therefore, in the context of providing healthy food and functional food based on upland red rice, which farming families can reach, and close to the location of the farmers' livelihoods, it is necessary to increase brown rice production through the introduction of brown rice cultivation technology as a garden plant and also as a family medicinal plant.

Upland rice is mostly grown in extremely diverse marginal upland ecosystems with highly degraded, infertile and acidic soils. The responses of selected upland rice varieties (Dinorado, Speaker, Ma. Gakit, and Cabuyok) to vermicast, Bio-N, and its combination were evaluated under Jasaan soil series in Claveria, Misamis Oriental from September 2013 to January 2014. The study was laid out following a 3 x 4 factorial in split-plot design with three replications. The Bio-N, vermicast and its combination served as the main plot while the upland rice varieties as the subplot. No synthetic chemical fertilizers and pesticides were used. Served application of vermicast, Bio-N and its combination did not influence the relative chlorophyll content of the leaves and dry matter accumulation of upland rice varieties before heading. It also did not influence the number of spikelets per panicle, weight per panicle, 1000 seeds weight and grain yield of the selected upland rice varieties. However, the significant effect of vermicast and Bio-N applied in combination revealed only at approximately three weeks after heading. Among the upland rice varieties, the grain yield of Speaker variety tended to be higher compared with other varieties. Results suggest that the farmer could either use vermicast, Bio-N, or in combination depending on the availability of the materials, and opt to use Speaker upland rice variety for its yield advantage.

Data analysis was performed using RAP-FARM through Multidimensional Scaling (MDS) method, leverage and prospective analysis. Based on the results, the sustainability index of upland rice farming for ecological (60.21) and socio-cultural dimension (56.98) were categorized as quite sustainable. Meanwhile, for economic (41.53), legal and institutional (27.80), technological and infrastructural dimensions (36.61) were classified as less sustainable. In multidimensional term, index value and sustainability status of upland rice farming were considered as less sustainable (44.63). On the leverage analysis, 15 sensitive attributes of 5 sustainability dimensions were acquired. On the prospective analysis, 6 key variables had a strong effect on the upland rice farming sustainability, namely last five-year government subsidies, inorganic fertilizer usage level, organic fertilizer usage level, straw utilization as organic fertilizer, rice price stability among farmers, and frequency of counseling and training activities. To improve the status of upland rice farming sustainability, efforts should be performed through intervening sensitive attributes and establishing a sustainability strategy.

Abstract Innovation to produce upland rice superior varieties is by developing local upland rice varieties with high yield and lodging resistance. Upland rice varieties also must have high adaptability in suboptimal land. This research aims to identify and determine the upland rice line F8 that is tolerant to lodging with high yielding potential.The research was carried out from September 2021 to January 2022 in Balunijuk Village Rice Fields, Bangka Regency. This research was conducted using an experimental method. The design used was a Randomized Block Design (RBD). The treatments consisted of 5 F8 lines and 5 comparison varieties. Data analysis used ANOVA followed by Duncan Multiple Range Test (DMRT). The results showed that generally upland rice genotypes were not able to adapt to inundation conditions, low pH, and Fe stress. Genotypes that were able to adapt were PBM UBB 1 (red rice), Danau Gaung and 21B-57-21-21-23 line (white rice), with the lodging index of 0% for these three genotypes, and a Fe toxicity scale with a value of sensitive. The genotype with the lowest yield was Inpago 8 and 23F-04-10-18-18 line. Genotypes with leaf length, number of grain per panicle, number and weight of pithy seeds per plant height increased seed yield/plot.

ρ-Cymene was one of the major components of volatiles released by croftonweed. The allelopthy of ρ-cymene on the growth of upland rice seedlings was performed. Hydrogen peroxide generation, malondialdehyde (MDA) content, proline content, total ascorbate (ascorbate/dehydroascorbate), reduced/oxidized glutathione, and the levels of induction of antioxidant enzyme were studied in the seedlings of upland rice. ρ-Cymene inhibited the growth of upland rice seedlings. Exposure of upland rice seedlings to ρ-cymene increased levels of H2O2, MDA, and proline, indicating lipid peroxidation and induction of oxidative stress. Activities of the antioxidant enzymes superoxide dismutase, catalase, peroxidase, guaiacol peroxidase, ascorbate peroxidase, and glutathione reductase were significantly elevated during the treatment period (7–15 d) compared with enzymes in the upland rice seedlings unexposed to ρ-cymene, thereby indicating the enhanced generation of reactive oxygen species (ROS) upon ρ-cymene exposure. These results suggest that activation of the antioxidant system by ρ-cymene led to the formation of ROS that resulted in cellular damage and decreased growth of upland rice seedlings.

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing and widely cultivated species in Indonesia. In addition, sengon is a type that is easy to adapt to the environmental conditions in which it grows. Upland rice (Oryza sativa L.) is a type of rice that is tolerant to drought. Sengon and upland rice in agroforestry can be an alternative in more effective land use. This study aims to measure local sengon growth, determine the productivity of upland rice in Inpago LIPI Go2 variety and light intensity in the sengon 1.5 m x 1.5 m and 1.5 m x 3 m line planting in agroforestry systems. Data analysis was performed by testing variance at the level of 0.05% and if the treatment had a significant effect, it was tested further using the Tukey Test. The results of this study indicate that sengon in the 6 months after planting is not affected by pathway treatment, but line planting treatment has a significant effect on upland rice productivity results. Beside age factor of sengon, it can be several other factors such as pest and disease attacks on sengon or upland rice.

Full textAbstract:
Purple rice is a functional food with health benefits and industrial potentials. In northern Thailand, purple rice landraces are grown either as wetland or upland rice, in the lowlands and highlands, in small amounts along with the staple rice. This study examined diversity of 37 accessions of purple rice collected from farmers with InDel cytoplasm markers for subspecies differentiation, 16 SSRs markers for within and between accessions variation, and selected grain quality features, namely, anthocyanin, iron, zinc, and gamma oryzanol content, when grown together as wetland rice. Most of the purple rice, originally grown as upland rice in both the lowlands and highlands, were identified as tropical japonica, except the wetland accessions from the lowlands that almost all belonged to the indica group. A high degree of genetic differentiation was found between the upland and wetland ecotypes, but none between those from the lowlands and highlands. A highland origin of the purple upland rice populations in the lowlands, possibly with adaptation to the upland rice cultivation of the tropical japonica, is suggested by the close genetic affinity between the highland and lowland populations of the upland ecotype. Grown in a much smaller area than the staple unpigmented rice, purple rice landraces are also less diverse genetically. Identification of purple rice landrace populations with exceptional anthocyanin and gamma oryzanol contents demonstrates that purple rice landraces can be a source of agronomically useful traits, while being an important cultural heritage, and contributing to the genetic diversity of the local rice germplasm.

Upland rice whose cultivated on dry land, which has limited needs for growth and production. The low upland rice production is due to the lack of high yielding varieties that can adapt, especially to marginal lands such as Ultisol. There are quite many local upland rice lines, but their potential has not been tested much. This study aimed to obtain the growth and yield of local upland rice cultivars of West Sumatra on the best Ultisol soil. The study used a completely randomized design (CRD) with four replications. The treatments were four upland rice cultivars, which consisted of; Silayang (K1), Siarang (K2), Sirah (K3) and Sigudang (K4). This data observation was analyzed for variance, and if it had a significant effect, it was continued using DMRT at the 5% level. Observations were made on plant height, the maximum number of tillers, percentage of productive tillers, length of flag leaf, age of flowering, age of the first harvest, panicle length, number of grain per panicle, the weight of 1000 pithy grain seeds, and weight of pithy grain per clump. Based on the results of the study, it was concluded that upland rice cultivar Sirah had the best growth and yield on Ultisol soil. Based on the conclusion, it is recommended to use Sirah upland rice on Ultisol soil.

Upland rice grows on 19 million ha, about 15% of the world's rice plantation [2]. The production of upland rice is crucial to agricultural economy of many countries [15]. The yield of upland rice is very low with an average of about 1 t/ha. Drought is a major constraint to the productivity of upland rice. In this paper, we present the results on mapping QTLs for root traits related to drought resistance (maximum root length, root thickness, root weight to shoot and deep root weight to shoot ratios) in upland rice using a recombinant inbreed (RI) population derived from a cross between Vietnamese upland rice accessions. The first molecular linked of Vietnamese upland rice were constructed. The map consists of 239 markers (36 SSR and 203 AFLP markers) mapped to all 12 rice chromosomes. This map covered 3973.1 cM of rice genome with an average distance of 16.62 cM between the markers. Twenty three putative QTLs were detected. Among them, four QTLs for MRL, four QTLs for R/SR, four QTLs for DR/SR, two QTL for RN, two QTLs for RT, two for PH, and five QTLs for TN were recorded. There are several SSR markers such as RM250, RM270, RM263, RM242, RM221 linked to QTL regions. They could be very useful for drought resistant selection in rice. Some common QTLs for maximum root length and deep root weight to shoot ratio were observed in different genetic background (RDB09 × R2021 and IR64 × Azorean populations) and ecological locations (IRRI and Vietnam). These QTLs could be very useful for precise locating drought resistant gene(s) and marker-assisted selection.

The development of rice irrigated farming is constrained by the conversion of land agricultural to non-agricultural. Therefore, policy to develop upland rice production in dryland and rainfed lowland is increasingly being implemented. Efforts to expand the application of technological innovations as a lever of upland rice production have intensified by introducing new superior varieties of upland rice. This research aims to analyze farmers' attitudes and satisfaction levels with introducing upland rice to attributes based. The location of this research is in Tegalgiri Village, Nogosari District, Boyolali Regency. Primary data were obtained through a survey method of 35 farmers who planted the Rindang 1, Rindang 2, Inpago 10, and Inpago 12 varieties. Farmer attitudes were analyzed using the Fishbein Multi-attribute Model, while farmer satisfaction level was analyzed using the customer satisfaction index (CSI). The results are the attributes "production" and "resistance to pests and diseases" were agronomic performance which was the most essential and primary consideration for farmers in choosing varieties. Farmers have a positive attitude towards the four new superior varieties. The meaning is that farmers want to adopt and plant the new superior varieties of upland rice. Farmers' satisfaction levels are in the "satisfied" to "very satisfied" category of the four new superior varieties. Hopefully, the new superior upland rice varieties that were introduced can be a choice of varieties by farmers.

Rice is an important commodity in Indonesia because rice is the main source of carbohydrates for the Indonesian. Rice production in Indonesia relies on lowland rice, but the productivity of lowland rice is decreasing. One of the efforts to increase rice national production is utilizing upland rice plants. The problem with upland rice is its low productivity. Nitrogen-fixing biological fertilizers can be used to increase the productivity of upland rice plants. The effect of different doses of nitrogen fertilizer and nitrogen fixing bacteria with different carrier materials on the growth and yield of upland rice in Inceptisols Jatinangor was studied. Randomized block design with two factors: the recommended dose of urea fertilizer (100% and 50%) and the nitrogen-fixing bacteria factor with different carriers (compost, rice bran, and Azolla powder) were applied as an experimental design. The experimental results showed that the interaction of nitrogen fertilizer dose and nitrogen-fixing bacteria with different carriers had no significant effect on plant height, number of panicles, root shoot ratio, and weight of 1000 grains of upland rice plants.

Abstract Increasing rice production is not only relied on from irrigated and rainfed rice fields, but also on dry land (upland rice). Development of upland rice on sub-optimal lands is one of the efforts to overcome the problem of vulnerability to rice availability, but until now its management is still not optimal. Minahasa District is one of the upland rice producing districts in North Sulawesi. This paper aims to identify matters related to sub-optimal land use for the sustainability of upland rice farming by farmers that can be developed in support of efforts to increase upland rice production in North Sulawesi, in addition to improving the existing technology used by farmers. This study was conducted in the Tombariri Subdistrict, Minahasa District, using a survey method. Data collection was carried out through field observations, surveys, documentation, in-depth interviews with key informants, and literature studies. The data obtained were then analyzed descriptively. Based on field identification and the results of the study, it was found that the existing local farmers’ technology was still very simple, especially in the aspects of seed supply, planting and maintenance. Farmers are increasingly pursuing development towards organic farming. There are still many sub-optimal land uses that can be optimized for upland rice cultivation accompanied by improvements to the existing limiting factors on each land.

Sandy coastal area in Indonesia is potential for upland rice cultivation, but it has constraints low of nutrient availability such as nitrogen. To solve the low fertility of the sandy land can be done by planting soybean between upland rice under intercropping system due to the soybean is able to provide nitrogen in soil through fixation of N2 in the air by root nodules. Intercropping is an alternative cropping system to increase land productivity, but there is competition between crops under an intercropping system. Reducing of the competition on the system is needed by crops proportion adjustment. The objective of the study is to examine growth and yield component of upland rice at different crops proportion under an intercropping system with soybean in the sandy coastal area. The research was conducted in Samas sandy coastal area, Bantul, Yogyakarta. This research used randomized complete block design (RCBD) with one factor and three blocks. The treatment of this research was five level crops proportion between upland rice and soybean under intercropping system, namely: 100:0; 80:20; 60:40; 40:60; and 20:80, respectively. The results showed that crop growth rate and yield per clump of upland rice increased on crops proportion adjustment under intercropping system with soybean. The crops proportion of 60:40 and 40:60 gave higher crop growth rates that were 1.45 g.dm-2.wk-1 and 1.44 1.45 g.dm-2.wk-1 than upland rice under monoculture (100:0) that was 1.09 g.dm-2.wk-1. The higher crop growth rates in crops proportion of 60:40 and 40:60 were able to give better yield per clump than other that were 17.17 g and 16.46 g, respectively. The yield of upland rice was not different under crops proportion of 100:0, 80:20, and 60:40 and decreased of upland rice proportion until ≤ 40% affected the low yield of upland rice.

Abstract kadon, daud d. 2019.Productivity and ecological sustainability of upland rice farming in the province of maguindano.Doctoral dissertation. Graduate school, university of southern mindanao, kabacan, cotabato. 184 pp. Major adviser: palasig u. Ampang, ph.d. The research study was conducted to determine the productivity and ecological sustainability of upland rice farming system in the province of maguindanao. One hundred three (103) farmers from 26 barangays of the province constituted the respondents. Descriptive statistics, correlation and multiple regression statistical tools were utilized. The test of hypotheses was set at 5% level of significance. The results revealed that upland farmers were generally males, married and were at least in their early 40s and finished intermediate education a family size ranging from 4 to 6 members had an income within the bracket of php 62,000 to 111,999 engaged in farming for a period of 17 to 24 years and were tilling 1 to 2 hectares of land but were non-members of agriculture-related organizations/association and had no trainings attended. Credit accessibility was never accessed rolling land was devoted to upland rice production. Tenurial status and membership in organization were found best significant predictors of the productivity of upland rice farming while age, civil status and number of trainings attended were found best significant predictors of ecological sustainability of upland rice farming. The socio-economic environment such as the source of information was found as the best significant predictors of the productivity of upland rice farming in the province of maguindanao. On bio-physical environment, soil type and cultural measure were found to have a significant influence on the productivity of upland rice farming in the province of maguindanao while level of destruction of insects, pests, diseases, rodents, birds and wild animals, seed selection, cropping pattern, cultural measure, mechanical measure and management of rice stubbles after harvest were found to significantly influence on the ecological sustainability of upland rice farming in the province of maguindanao.

Full textAbstract:
Aerobic rice has the potential to replace transplanted flooded rice, as rice cultivation is seriously threatened by environmental and social factors. Although the recently released upland rice cultivars have higher drought tolerance, low yield potential of these cultivars makes them less feasible for high-yielding rice planting regions under aerobic cultivation. In this study, typical lowland rice cultivars (Huanghuazhan and Yangliangyou6) were evaluated for grain yield and resource use efficiencies under aerobic cultivation as compared with upland rice cultivars (Lvhan1 and Hanyou3). Averaged across different years, lowland rice cultivars recorded 26.9%, 14.6%, and 26.6% higher grain yield, water productivity, and nitrogen use efficiency for grain production (NUEg), respectively, as compared with upland cultivars. The higher grain yield of lowland rice cultivars under aerobic cultivation was mainly attributed to the higher aboveground biomass and the spikelet number per panicle, along with a higher harvest index and panicle number per unit area with respect to upland rice cultivars. During the entire growing season in aerobic cultivation, rainfall accounted for 60% to 85% of the total water use, which indicates that lowland rice cultivars could make better use of the rainfall because of a longer growth duration and a higher growth potential. In summary, this study suggests that with appropriate irrigation, lowland rice cultivars could grow well and furnish higher yield than the current upland rice cultivars under aerobic cultivation.
