This book was released on 2020 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop diversification can reduce weed-crop competition and contribute to ecological weed management, but the mechanisms by which crop diversity reduces weed-crop competition and the persistence of those effects are poorly understood. The legacy effects of crop diversity on weed-crop competition were tested after a multi-year field experiment that compared conspecific and heterospecific crop diversity in intercropped annual and perennial systems. In a greenhouse experiment, soil from the field experiment was collected and manipulated to elucidate the effects of soil microbes in determining weed-crop competition. After the final harvest in the field experiment a uniformity trial was conducted to evaluate the effects of crop diversity on weed community structure and compare weed-crop competition. In both cases, crop diversity had minimal effects on weed-crop competition. However, the annual and perennial cropping systems that contextualized the diversity treatments consistently influenced microbial plant-soil feedbacks, crop nutrient uptake, weed communities, and weed-crop competition.

Download or read book Evaluating Plant Functional Diversity in an Organic Intercropping System written by Jose Franco and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Overyielding, a phenomenon whereby plant production in mixture exceeds that of production in monoculture, has been attributed to complementary use of resources by different plant functional types. Few studies have examined the role of plant functional diversity and the concept of overyielding in food production systems. Different combinations of peanut (Arachis hypogaea L.), watermelon (Citrullus lanatus Thunb.), okra (Abelmoschus esculentus Moench.), cowpea (Vigna unguiculata L.), and pepper (Capsicum annuum L.) planted alone or in various intercropping combinations were investigated over two growing seasons in an organic system in the peak of summer heat in Texas. Results from land equivalent ratio (LER) indicate that the within-row intercropping combination of peanut, watermelon, and okra (Wpwo) and the four species combination with the addition of cowpea (Wpwoc) consistently overyielded both growing seasons, despite a reversal in dominance patterns exhibited by watermelon and okra between years. There was no effect of intercropping system on changes in total nitrogen (N) or soil organic carbon (SOC). However, soil microbial biomass carbon (SMB-C) was lower in Wpwo as compared to okra grown in monoculture. Although there was no difference in root length density (RLD) between cropping system, there was a significant positive linear relationship between RLD and SMB-C. Low leaf area index (LAI) values in cowpea and peanut monocultures resulted in higher daily soil temperatures and an increase in weed biomass. There was a strong inverse relationship between LAI and soil temperature, particularly with daily maximum soil temperature. No differences in physiological parameters were detected. In 2012, when watermelon was a subordinate crop, specific leaf area (SLA) and leaf N content were highest in the multispecies systems, particularly Wpwoc. Carbon to nitrogen ratio (C:N) was also lowest in Wpwo and Wpwoc as compared to watermelon grown in monoculture indicating watermelon underwent morphological changes at the leaf level due to competition for light and allocated less C to leaves when competition was reduced. Overall findings suggest that three and four species intercropping combinations, whereby each crop is selected to perform a specific function within the system, may provide small-scale sustainably-minded producers a model system that can be utilized in the peak of summer in southern climates and allow them to reduce inputs while increasing overall yields.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change has intensified in recent decades, which has affected crop production as well as facilitated the emergence of new diseases and insect pests, causing serious threats to agriculture. Farmers have mostly taken a crop-based approach to insect pest management (IPM); the authors of this new volume, however, take the unique approach that IPM based on specific cropping systems is more efficient, resulting in reduced cultivation costs, increased yield and profitability, and decreased residue from crop produce and products. This volume presents the results of research done by crop protection scientists on integrated pest management in diverse cropping systems based on rice, wheat, maize, pulses, food legumes, oilseeds, groundnut, potato, and other horticulture crops. With chapters written by well-known and experienced scientists in their fields, this volume provides in-depth knowledge on integrated pest management in conjunction with an array of specific cropping systems, taking into consideration all the elements, including the crops, crop sequences, spatial and temporal aspects of managing an agricultural system, and other aspects. This volume will be valuable for entomologists, plant pathologists, and agronomists, as well as for farmers—both small and industrial sized, agricultural extension centers, faculty and students, and many others involved with crop cultivation.

Available in PDF, EPUB and Kindle. Book excerpt: Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality

This book was released on 2023-08-28 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The edited volume focuses on modern agro-technologies for achieving climate smart agriculture in China and meeting the UN sustainable development goals (especially SDGs 2, 13, and 15). It describes the technologies being adopted in China for meeting food security challenges, with the main focus being on soils. China is a large and diverse country, and what happens there has a global impact. In the past decades, China has achieved remarkable increases in food production, feeding nearly 20% of the world population with less than 10% of the arable land. This great achievement was mainly based on the intensive use of chemical inputs like fertilizers and pesticides, which in turn caused environmental pollution and food safety issues. China has fully realized this important issue and has adopted a “Zero Growth” policy to restrict the further increase in chemical fertilizers after 2020. Chinese scientists have developed regional optimum crop management practices and guidelines to increase crop yield and nutrient use efficiencies compared with current farming practices. Chinese agricultural soil is also currently in critical condition with severe environmental pollution. These agricultural practices need improvement to maintain sustainable food production with minimum environmental footprint. At present, the traditional mode of agricultural production in China is difficult to sustain. This book offers case studies and sustainable solutions for transforming agricultural sciences in China. The book is a useful reading material for stakeholders such as governments, policymakers, research institutions, and farmers.

Download or read book Functional Diversity in Summer Annual Grass and Legume Forage Intercrops written by Kristine Ann Bybee-Finley and published by . This book was released on 2016 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reintroducing crop diversity and reducing external inputs are important initial steps to a more sustainable agriculture. The role of functional diversity was explored in an annual forage intercropping system. Four warm-season, drought-tolerant annual forage crops were evaluated for use in the Northeast United States. The species had two different functional traits, stature and nitrogen acquisition traits: 1) cowpea (Vigna unguiculata L., legume, short); 2) sunn hemp (Crotolaria juncea L., legume, tall); 3) pearl millet (Pennisetum glaucum L., grass, short); and 4) sorghum sudangrass (Sorghum bicolor L. Moench x S. sudanense P., grass, tall) and were seeded in monocultures and in three and four species intercrops. Crop and weed biomass were sampled twice by clipping vegetation in 0.5 m2 area at approximately 45 and 90 days after planting (DAP). When averaged across site-years, crop biomass and crop growth rate of legume monocultures were lower than other treatments at both sampling times. Biomass for the monocultures at the second sampling date ranged from 2,500 kg ha-1 (cowpea) to 9,300 kg ha-1 (pearl millet). No biomass differences were found between the intercrops and grass monocultures, which ranged from 7,800 to 9,600 kg ha-1. Although the intercrop treatments did not produce more biomass than the two grass monoculture treatments, all intercrops had land equivalent ratios (LER) greater than 1. Grasses and intercrop treatments were similarly weed suppressive. The pearl millet-sorghum sudangrass-sunn hemp intercrop consistently produced the most biomass, but not significantly more than the pearl millet monoculture, which had a much lower seed cost. Therefore other potential benefits of summer annual forage intercrops (e.g. improved forage quality and increased soil health) must be considered to justify the increased seed costs. v.

Book excerpt: This book offers comprehensive insights into the management of agroforestry for livelihood security and sustainable development in the tropics, addressing ecological interactions, productivity, and the monetization of carbon credits, while also outlining a future roadmap and policy challenges. Agroforestry is a brilliant land use farming practice that covers 1.6 billion hectares (78 percent in the tropics and 22 percent in the temperate regions) to enhance plant diversification, productivity, and livelihood across generations, maintaining eco-restoration. It ensures socioeconomic upliftment and a standard livelihood for people along with many ecosystem services for sustainable development under resilient climates, which are today’s key topics popularized among policy makers, stakeholders, scientists, ecologists, and climate supporters in the tropical world. However, more than 75 percent of the world’s poor directly depend on natural resources for their livelihoods. Adopting climate resilient agroforestry not only maximizes productivity and farmers’ socioeconomic status but also mitigates climate change issues through carbon sequestrations for better carbon management in the tropics. This book addresses agroforestry management for livelihood security and sustainable development in the tropics. Readers will earn about ecological interactions and productivity in tropical agroforestry ensuring greater ecosystem services and livelihood resilience under changing climates, as well as building livelihood resilience through monetization of carbon credits in agroforestry in the tropics. Livelihood and sustainability-based policy in agroforestry, its challenges, and a future roadmap are also covered. This volume provides new insights related to updated research, development and extension activities for combating climate change through carbon sequestration to enhance intensify greater productivity, and livelihood and ecosystem services for ensuring the goals of sustainable development.
