Book excerpt: In response to the Royal Cambodian Government's National Poverty Reduction Strategy (2003–2005), ACIAR funded research to develop sustainable farming systems for crops, with a focus on maize, soybean, sesame, mungbean, peanut and cowpea in upland areas of Kampong Cham and Battambang provinces. The aim was to help reduce poverty and contribute to food security at household and national levels through the development of technologies and opportunities for the production of non-rice upland crops. The research process involved discussion with farmers, validation of local knowledge, documentation of case studies and identifying priorities for field experimentation. This book is part of a series of publications produced by ACIAR in support of the on-going rollout of on-farm demonstrations for upland crops in Cambodia.

Download or read book Technical guidance on fall armyworm written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2022-05-27 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, maize is the third most important cereal after rice and wheat. It occupies 197 million hectares of planted area. Asia contributes to nearly 30 percent of global maize supplies, and area and production of the crop is rapidly increasing in the continent. Minimum support prices, swelling market demand from the animal feed and processing industries, as well as human consumption, have all led to increased maize production in zones where precipitation limits rice cultivation. However, maize production is currently threatened by the arrival in Asia (in 2018) of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) – a native to North America. It invaded India in 2018 and since then it has marched to most of the Asian countries. In 2019, its presence was confirmed in 13 Asian countries including Cambodia, China, India, Indonesia, Japan, the Lao People’s Democratic Republic, Malaysia, Myanmar, Nepal, the Philippines, the Republic of Korea, Sri Lanka, and Viet Nam. In 2020, it was confirmed in Australia, Timor-Leste and Papua New Guinea. In August 2021, it reached the Solomon Islands, posing a serious threat to other Pacific islands. FAW is a fast-dispersing, migratory, transboundary insect pest. While high FAW incidences have been reported on several crops in Asia, the most important economic damage caused is to maize (followed by sorghum). The FAW invasion threatens the food security of millions of family farms in Asia, with smallholder farmers being especially vulnerable. The negative economic impact of FAW is not only evident in yield loss: the pest also leads to a significant increase in insecticide applications, with associated health, environmental and cost issues. At the same time, resilience to FAW on the continent is currently weakened by the limited access to necessary tools, technologies and sustainable integrated pest management (IPM) practices for FAW. Thus, there is an urgent need to implement an effective approach to FAW management in Asia.

Download or read book Compendium of Bioenergy Plants written by Stephen L. Goldman and published by CRC Press. This book was released on 2014-02-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates maize as a bioenergy fuel source from two perspectives. It explores whether the input energy needed to generate fuel significantly exceeded by the energy harvested. In examining this issue, the chapters provide assessments of the social, economic, and political impact on fuel pricing, food costs, and the environmental challenge with corn biomass the engine of change. It then examines whether corn be genetically improved so that its biomass is significantly increased, its cellulose-lignin complex made more amenable to harvesting and to processing, and grown in regions not normally associated with its cultivation of food.

Download or read book Maize Agroecosystem written by K. R. Krishna and published by CRC Press. This book was released on 2012-07-19 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is among the most widely spread and widely used crops of the world, used for cereals for over 4 billion humans, as food for farm animals, and as a source material for biofuel production. Yet there are relatively few books on the cropping system of this important crop. This book, Maize Agroecosystem, is a concise treatise dealing with agronomy, soil fertility, and productivity of maize. The information is global in nature and considers recent developments in all maize cropping belts. The "global maize agroecosystem" is a conglomerate of several "maize cropping belts" that flourish on different continents. The impact of nutrient management on the productivity of maize agroecosystems is the main focus of this book. The book includes the history of maize growing, the kinds of soil needed, nutrient dynamics, the use of soil organic matter, the physiology and genetics of maize, and integrated nutrient management. It presents comprehensive knowledge regarding the physicochemical dynamics of the three major nutrients: nitrogen, phosphorus, and potassium. Also covered is how fertilizers impinge on soils of maize farms and their impact on soil and groundwater quality. The impact of crop genotype on soil nutrient dynamics and productivity is also highlighted. The information provided here will be highly useful to students at colleges and universities in the fields of agricultural sciences and environmental science and ecology, and the book also functions as valuable resource for researchers and professors in crop science. Several figures and tables are included that describe and summarize the impact of various agronomic/fertilizer management procedures on crop productivity.

Download or read book Cambodian Agriculture written by Timothy S. Thomas and published by Intl Food Policy Res Inst. This book was released on 2013-08-22 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cambodia has been identified as one of the most vulnerable countries to climate change, given the predicted changes in temperature and precipitation, the share of labor in agriculture, and the country’s low adaptive capacity due to widespread poverty. In this study, we use climate data from four general circulation models (GCMs) to evaluate the impact of climate change on agriculture in Cambodia by 2050. We used the Decision Support System for Agrotechnology Transfer crop modeling software to evaluate crop yields, first for the 1950–2000 period (actual climate) and then for the climates given by the four GCMs for 2050. We evaluated crop yields for eight different crops at 2,162 points in Cambodia, using a grid of 10-kilometer squares, for 2000 and 2050. For each crop, we searched for the best cultivar (variety) in each square, rather than assuming the same cultivar to be used in all locations. We also searched for the best planting month in each square. We explored potential gains from changing fertilizer levels and from using irrigation to compensate for rainfall changes. This analysis indicates that when practiced together, using improved cultivars better suited for the changing climate conditions and adjusting planting dates can lessen the impact of climate change on yields, including for both wet- and dry-season rice. In addition, the analysis shows that losses in yield due to climate change can be compensated for—for many crops—by increasing the availability of nitrogen in the soil. To provide context to the modeling analysis, a survey of 45 communes was conducted using focus group discussions to solicit information on agricultural practices. Questions were asked about fertilizer, irrigation, seeds, tillage, and pest management, as well as about natural disasters and how farmers respond. Key results indicate that in response to extreme weather, only 7 to 16 percent of farmers report changing crop variety and only 20 percent of farmers report changing planting dates. Since the modeling results indicate that adaptation to climate change by changing crop variety and planting dates will be critical in order to avoid yield losses over the next 40 years, it is recommended that farmers expand their capacity to adapt in this way. In addition, every commune reported using some type of chemical fertilizer; however, in a typical commune, only 50 percent of the farmers were using any chemical fertilizer. This indicates that there is room to increase the use of chemical fertilizers. Finally, focus group participants were asked to name the top three natural disasters of concern. Drought was the most cited, reported in 44 of the 45 communes (98 percent), while flooding was cited in 67 percent of the communes surveyed. Despite this, in fully 58 percent of the communes, farmers reported taking no action in response to floods. In response to drought, farmers reported switching to other crops in 16 percent of the communes, and changed planting dates in 19 percent, while only 7 percent of the communes reported no adaptation in farming practices. These findings indicate the need for intervention to help farmers deal with floods in particular, and to determine whether strategies for adapting to drought are the best suited to mitigate crop loss.
