Chauhan, B. S.; Opena, J., 2014, "Effect of tillage systems and herbicides on weed emergence, weed growth, and grain yield in dry-seeded rice systems", https://doi.org/10.7910/DVN/23750, Harvard Dataverse, V2
Farmers in many Asian countries are moving from puddled-transplanted rice to dry-seeded rice systems. Dry-seeded rice can be sown after land preparation or under zero-till conditions. Weeds, however, are the major constraint to the production of dry-seeded rice. A study was conducted during the wet season of 2011 and dry season of 2012 at the farm... |

Flor, Rica Joy; Singleton, Grant, 2014, "Analysis of communication pathways and impacts of the Boo! Boo! Rat! campaign", https://doi.org/10.7910/DVN/23832, Harvard Dataverse, V1
To help rice farmers overcome problems of chronic rodent infestation, the Boo! Boo! Rat! campaign was implemented in Zaragosa, Nueva Ecija, Philippines. The campaign promoted ecologically based rodent management (EBRM) as a community-level management approach. Our study was conducted one year after the campaign to evaluate its success in promoting... |

Chauhan, Bhagirath Singh, 2014, "Weedy rice (Oryza sativa) II. Response of Weedy Rice to Seed Burial and Flooding Depth", https://doi.org/10.7910/DVN/23777, Harvard Dataverse, V1
Weedy rice is a serious problem of cultivated rice in most of the rice-growing areas in Asia, causing increased production costs and yield losses in rice. A study was conducted to determine the response of weedy rice accessions from India (IWR), Malaysia (MWR), Thailand (TWR), and Vietnam(VWR) to seed burial and flooding depths. The greatest emerge... |

Chauhan, Bhagirath Singh; Abugho, Seth Bernard, 2014, "Threelobe Morningglory (Ipomoea triloba) Germination and Response to Herbicides", https://doi.org/10.7910/DVN/23748, Harvard Dataverse, V1
Experiments were conducted in the laboratory and screenhouse to determine the effects of scarification; alternating day/night temperatures; light, salt, and water stress; seed burial depth; and rice residue on seed germination and seedling emergence of threelobe morningglory, and to evaluate the response of this weed to commonly available POST herb... |

Chauhan, Bhagirath; Mahajan, Gulshan; Sardana, Virender; Timsina, Jagadish; Jat, Mangi, 2014, "Productivity and Sustainability of the RiceeWheat Cropping System in the Indo-Gangetic Plains of the Indian subcontinent: Problems, Opportunities, and Strategies", https://doi.org/10.7910/DVN/23749, Harvard Dataverse, V1
Rice and wheat are the staple foods for almost the entire Asian population and therefore they occupy a premium position among all food commodities. The era of the Green Revolution started during the early 1970s with wheat and rice and since then the ricee-heat cropping system of the Indo-Gangetic Plains has played a significant role in the food sec... |

Chandna, Parvesh; Ladha, J.K.; Singh, U.P.; Punia, Milap; Gupta, Raj; Sidhu, B.S., 2014, "Using remote sensing technologies to enhance resource conservation and agricultural productivity in underutilized lands of South Asia", https://doi.org/10.7910/DVN/23665, Harvard Dataverse, V1
Satisfying the food demands of an ever-increasing population, preserving the natural resource base, and improving livelihoods are major challenges for South Asia. A large area of land in the Middle and Lower Gangetic Plains of South Asia remains either uncultivated or underused following the rice harvest in the kharif (wet) season. The area include... |

Chauhan, Bhagirath Singh; Abugho, Seth Bernard, 2014, "Effects of water regime, nitrogen fertilization, and rice plant density on growth and reproduction of lowland weed Echinochloa crus-galli", https://doi.org/10.7910/DVN/24108, Harvard Dataverse, V2
Direct-seeded rice systems are increasing in Asia as farmers respond to the high labor cost and shortage of water. Echinochloa crus-galli is one of the most problematic and competitive weeds in direct-seeded rice systems. Because of concerns about excessive herbicide use, there is an interest in developing cultural weed management strategies. Howev... |
Burac, Mary Ann; Boling, Anita; Tuong, To Phuc; Harnpichivitaya, D.; Rajatasereekul, S., 2013, "Relationships of leaf color chart and SPAD values to leaf N content of Jasmin rice in Northeast Thailand", https://doi.org/10.7910/DVN/XK5NOP, Harvard Dataverse, V2
Strong correlations among the leaf color chart (LCC), chlorophyll meter (SPAD) readings, and leaf N concentrations in modern rice varieties provide simple and economical methods for indirectly determining leaf N content. The LLC and SPAD have not been used widely with traditional varieties. This study aimed to determine whether the LCC and SPAD cou... |

Vermeulen, Hanneke; Bouman, B. A. M.; de Ridder, N., 2013, "Evaluation of the Aerobic Rice technology: three years of experiments in the Philippines", https://doi.org/10.7910/DVN/X66QRZ, Harvard Dataverse, V3
In 2005 an overview was made of the field experiments that were conducted by the Water Science Group. This was done by an MSc student Matthijs Bouwknegt to get some preliminary ideas about the performance of aerobic rice under experimental conditions. Not all experiments were completed by then. The year 2005 has marked the end of a series of experi... |
