Upland Rice and Allelopathy
Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...
متن کاملRice Allelopathy and Momilactone
Rice has been extensively studied with respect to its allelopathy as part of a strategy for sustainable weed management options. All available information indicates that rice plants possibly release unknown allelochemicals into the neighbouring environments. A large number of compounds, such as phenolic acids, fatty acids, indoles and terpenes, were identified in rice root exudates and decompos...
متن کاملRice—A Step Toward Use of Allelopathy
house and field experiments. Research to accomplish the above goals cannot be carried out in one laboratory, Rice (Oryza sativa L.) allelopathy has been on the research agenda and needs active collaboration among a wide range of for a decade. Now it is important to step back and look at its progress to enable priority setting for future research. This paper aims to do scientists, including biol...
متن کاملIntegration of Allelopathy to Control Weeds in Rice
Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sou...
متن کاملInterpreting Upland Rice Yield and Pratylenchus zeae Relationships: Correspondence Analyses.
Correspondence analyses were used to explore the relationships between yield and populations of Pratylenchus zeae in an upland rice field and in a greenhouse experiment. Initial soil (Pi) and final root (Pf) population densities of P. zeae, and yield (Y) of rice cv. UPL Ri5 were determined at 490 spots in the field. Very low Y was linked to very high Pf. Low Y was linked to medium or high Pi an...
