Profitability and Health Risk Estimation of Rice Cultivation under Wastewater Irrigation from Natural Drainage
The paper reports the results of an empirical study on the profitability of rice cultivation in the rural areas of Allahabad by wastewater irrigation from natural drainage. The results show that plots using wastewater containing organic nutrients earn higher profits than those using groundwater. However, we also find the profitability of plots using wastewater negatively affected by the presenc...
متن کاملKnowledge level of rice farmers regarding rice cultivation practices in Mahanawiyah district, AL- Qadisiya Province, Iraq
Productivity of most common Iraqi rice cultivar was low compared to an average production among major rice-producing countries, this may be due to inadequacy of knowledge and skills of rice farmers about rice cultivation practices. The study was conducted in Mahanawiyah district of AL-Qadisiya Province in Iraq, to assess knowledge level of rice farmers about some rice cultivation practices .The...
متن کاملMunicipal Wastewater Irrigation for Rice Cultivation
In scene of worrisome water shortage, municipal wastewater has been gradually accepted as an alternative water resource containing important nutrients for irrigation. Rice cul‐ tivation, which is one of the main crops feeding global population and requires plenty of water for its effective growth, has been often irrigated by municipal wastewater in many countries. While irrigation of municipal ...
متن کاملGenetic Loci Governing Grain Yield and Root Development under Variable Rice Cultivation Conditions
Drought is the major abiotic stress to rice grain yield under unpredictable changing climatic scenarios. The widely grown, high yielding but drought susceptible rice varieties need to be improved by unraveling the genomic regions controlling traits enhancing drought tolerance. The present study was conducted with the aim to identify quantitative trait loci (QTLs) for grain yield and root develo...
