Chauhan, Bhagirath Singh; Abugho, Seth Bernard, 2014, "Phenotypic Plasticity of Spiny Amaranth (Amaranthus spinosus) and Longfruited Primrose-Willow (Ludwigia octovalvis) in Response to Rice Interference", https://doi.org/10.7910/DVN/23671, Harvard Dataverse, V1
The growth of spiny amaranth and longfruited primrose-willow was studied by growing them alone and in competition with 4 and 12 rice (cv. RC222) plants. Interference with 12 rice plants reduced the height of spiny amaranth beyond 6 wk after planting. The height of longfruited primrose-willow was significantly reduced by the crop interference starti... |

Dar, S. R.; Thomas, T.; Dagar, J. C.; Lal, Khajanchi; Mehboob, Samreen; Bakshi, Megna Rashid; Mir, A. H.; Mir, Hidayatullah; Kumar, A.; Malik, R. K., 2014, "Effect of fertilizer nitrogen and varied C:N ratio of mushroom compost on rice yield and nitrogen forms of soil", https://doi.org/10.7910/DVN/23781, Harvard Dataverse, V1
Field experiment was conducted to evaluate effect of spent mushroom composts of varied C:N ratio with and without fertilizer nitrogen on yield, nitrogen uptake and nitrogen forms in rice grown on the Inceptisol of Allahabad. Nitrogen mineralization from oyster spent mushroom compost (OYSMC) was slower than from white button spent mushroom compost (... |

Chauhan, Bhagirath Singh; Singh, Ravi Gopal; Mahajan, Gulshan, 2014, "Ecology and management of weeds under conservation agriculture: A review", https://doi.org/10.7910/DVN/23752, Harvard Dataverse, V1
Tillage has been known to cause soil erosion and cost time and resources and this affects productivity and inflates the cost of production. Therefore, over the past few years in many countries, there has been a growing trend toward conservation agriculture (CA) to enhance sustainability without compromising land productivity. Three important pillar... |

Hoanh, Chu Thai; Phong, Ngo Dang; Trung, Nguyen Hieu; Dung, Le Canh; Hien, Nguyen Xuan; Ngoc, Nguyen Van; Tuong, To Phuc, 2014, "Modelling to support land and water management: experiences from the Mekong River Delta, Vietnam", https://doi.org/10.7910/DVN/23779, Harvard Dataverse, V1
By comparing the successful story of a hydrodynamic model (based on its contribution to policy changes, management options and livelihood improvement) with other modeling cases in the Mekong River Delta, five success factors are identified. These are (1) simulated phenomena relevant to and understandable by policy makers; (2) response to the needs... |

Clerget, B; Rattunde, H.F.W.; Weltzien, E., 2014, "Why tropical sorghum sown in winter months has delayed flowering and modified morphogenesis in spite of prevailing short days", https://doi.org/10.7910/DVN/23780, Harvard Dataverse, V1
Sowing certain late photoperiod-sensitive tropical sorghum varieties under short-day conditions in November-January in the northern hemisphere can result in a pronounced delay in flowering and prostrate, high-tillering forms similar to the rosettes in winter small-grain cereals. The cause of this phenomenon in sorghum has long been questioned and i... |

Siopongco, Joel; Wassmann, Reiner; Sander, B.O., 2014, "Alternate wetting and drying in Philippine rice production: feasibility study for a Clean Development Mechanism", https://doi.org/10.7910/DVN/23828, Harvard Dataverse, V1
Water-saving technologies such as alternate wetting and drying (AWD) provide a way to change practices to improve the livelihoods of many rice farmers and AWD is regarded as one of the more important rice cultivation methods that can dramatically save freshwater irrigation in this century. AWD not only conserves water but also mitigates greenhouse... |

Nyo Me Htwe; Grant R. Singleton; Lyn A. Hinds; Catherine R. Propper; Vincent Sluydts, 2014, "Breeding ecology of rice field rats, Rattus argentiventer and R. tanezumi in lowland irrigated rice systems in the Philippines", https://doi.org/10.7910/DVN/23833, Harvard Dataverse, V1
Rodents are one of the major pests in lowland irrigated rice crops in the Philippines. Rattus tanezumi occurs throughout the Philippines, whereas Rattus argentiventer does not occur on the main island of Luzon. Little is known about the breeding ecology of R. argentiventer and R. tanezumi where they coexist in the Philippines. We hypothesised that... |

Gaydon, D.S.; Probert, M.E.; Buresh, R.J.; Meinke, H.; Suriadi, A.; Dobermann, A.; Bouman, B.; Timsina, J., 2014, "Rice in cropping systems - Modelling transitions between flooded and non-flooded soil environments", https://doi.org/10.7910/DVN/23782, Harvard Dataverse, V1
Water shortages in many rice-growing regions, combined with growing global imperatives to increase food production, are driving research into increased water use efficiency and modified agricultural practices in rice-based cropping systems. Well-tested cropping systems models that capture interactions between soil water and nutrient dynamics, crop... |

Chauhan, Bhagirath; Abugho, Seth, 2014, "Interaction of Rice Residue and PRE Herbicides on Emergence and Biomass of Four Weed Species", https://doi.org/10.7910/DVN/23667, Harvard Dataverse, V1
Studies were conducted in a screenhouse to determine the interaction of rice residue as mulch (0, 3, and 6 t/ha) and herbicides (nontreated, oxadiazon at 0.5 and 1.0 kg ai/ha, and pendimethalin at 1.0 and 2.0 kg ai/ha) on seedling emergence and biomass of barnyardgrass, crowfootgrass, junglerice, and rice flatsedge. Regardless of the residue amount... |

Gowda, Veeresh; Henry, Amelia; Vadez, Vincent; Shashidhar, H. E.; Serraj, Rachid, 2014, "Water uptake dynamics under progressive drought stress in diverse accessions of the OryzaSNP panel of rice (Oryza sativa)", https://doi.org/10.7910/DVN/23794, Harvard Dataverse, V1
In addition to characterising root architecture, evaluating root water uptake ability is important for understanding drought response. A series of three lysimeter studies were conducted using the OryzaSNP panel, which consists of 20 diverse rice (Oryza sativa L.) genotypes. Large genotypic differences in drought response were observed in this genot... |
