Enhancing upland rice production is one solution to achieve rice sufficiency in the country. Improved genotypes contribute to this goal at a relatively low cost to farmers, but available resources need to be assessed first. This study determined the availability of upland rice landraces and traditional varieties (URLTVs) in selected areas of Bukidnon, estimated the seed diversity of available genotypes, and documented their use. Twenty-four Barangays from 10 municipalities and 2 cities were surveyed from November 2010 to May 2011. Interviews (n=45), seed sourcing, and evaluation of 13 seed traits were done. One hundred forty URLTVs were collected, of which 82 (59%) were from San Fernando, Bukidnon whose peoples were mostly of the Matigsalug tribe. Shannon-Weaver Diversity estimates for 100 seed weight, grain length and width, grain thickness, caryopsis length and width, and lemma: apiculus color showed high diversity (H’=0.76 to 0.88). URLTVs were grown for household consumption, church offering and for special occasions, and to reduce chemical inputs. For the Matigsalugs, their URLTVS serve to strengthen their cultural beliefs and are trademarks for their tribal group. Collection from other areas of Bukidnon needs to be done to ascertain other available germplasm and possible threats to these plant genetic resources.

Study Design: Descriptive case series. Place and Duration of Study: District HeadquarterHospital (DHQ) Temargarah & Lady Reading Hospital Peshawar and, Ghurki Trust TeachingHospital, Lahore from Dec 2014 to Nov 2015. Material and Methods: Patients of either genderor all ages received in outpatient department or accident and emergency of DHQ Temargarah,Lady Reading Hospital Peshawar and Ghurki Trust Teaching Hospital, Lahore with history oftrauma followed by treatment by local bonesetters were included in our study. After properhistory, examinations and investigations, appropriate treatment were given and complicationswere noted. Results: We received a total of 267 patients who were treated by Traditional bonesetters.186 were males and 81 were females. Age ranges from 1.5 years to 87 years. In majorityAdvice or pressure from family/friends taking the lead. 77(28.84%) of patients suffer because offamily or friends. 66(24.72%) of patients affected because of socio cultural beliefs, 46(17.23%)because of low cost, 35(13.11%) because of ignorance, 24(8.98%) because of fear of operation,19(7.12%) because of fear of amputation took their treatment from bone setters. The mostfrequent complication we received was malunion were found in 67(25.10%) and non-union in55(20.60%), Conclusion: Pressure from friends and family was the main reason for consultingTraditional Bone Setters for treatment in our set up and complications caused by their treatmentwere frequent and ranged from immediate compartment syndrome and gangrene of the limb tolate onset mal union, non-union and avascular non-union.

The land is an important factor for people whose lives depend on the agricultural sector. The need for land for various uses has resulted in decreasing agricultural land which could have implications for decreasing food production. Alternative options which are expected to increase the potential for food production are the utilization of marginal land. Farmers with marginal land need to manage their production to meet household needs. So it is important to examine the marketable surplus, the level of commercialization, and the carrying capacity of marginal land. The research area was taken by purposive sampling method in Gunungkidul Yogyakarta. The samples taken were upland rice farmer households with the simple random sampling method. The marketable surplus analysis uses a marketable surplus formula, then the percentage is used to determine the level of farm commercialization. The carrying capacity analysis is carried out using the carrying capacity formula. The results showed that farmer households manage rice production by allocating an average of 59.1% for marketed and 40.9% for household consumption. The allocation of marketable surplus is greater than for household consumption, this shows that gogo rice farming households are towards commercially. The marginal land carrying capacity of 0.641 indicates that the land cannot be developed in an expansive and exploratory manner. The implication is in increasing upland rice production on marginal land, namely by an intensification of farming.

Traditional Rice

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.

AbstractRice is the most important agricultural commodity of the Lao People's Democratic Republic (Lao PDR), produced largely using traditional methods with limited inputs of fertilizers and other chemicals. The country has a wide diversity in rice production systems and rice varieties, with over 3000 different varieties recorded. The rich diversity and the production environment and methods are favorable for organic rice production. Investigations were carried out to describe soil fertility conditions, management practices, opportunities and problems associated with organic production methods for rice. Soils used for rice production are mostly of low fertility, with low organic matter and N-availability. In spite of this, virtually no fertilizer inputs are used for upland rice production. Inorganic fertilizer inputs for lowland rice production have increased rapidly over the past decade, but are still below 20 kg ha−1. The most important nutrient sources are rice straw and manure from buffalo and cattle. Chromolaena odorata plays an important role in nutrient cycling in upland rice systems and is sometimes added to lowland fields. In a range of fertility management studies, yield increase ranged from 2 to 89% for manure, straw or rice husk applied at modest rates (3 t ha−1), 32–156% for modest rates of inorganic fertilizer (60 kg N ha−1) and 36–167% for combined application of manure or crop residues with inorganic fertilizer. The response to locally produced commercial organic fertilizer was poor. The most promising inputs and strategies available to optimize yields in organic rice production systems are (1) optimizing use of locally available nutrients, mostly from manure, crop residues and weed biomass, (2) N addition through green manure and legumes growing in rotation and (3) additions of P through guano or rock-phosphate. The Lao PDR is fortunate to have substantial bat guano deposits in limestone caves. Extensive experience is available on straw and husk management for lowland systems and green manure species for upland production systems.
