چکیده
To reveal the effect of biochar addition on rice growth and yield under water-saving irrigation, a 2-year field experiment was carried out to clarify variations tiller number, plant height, components, irrigation water use efficiency with different application amounts (0, 20, 40 t/ha) management (flooding irrigation). The results showed that (20 15.53% 24.43% higher than non-biochar paddy fields irrigation. promoted tillers improved filled grain productive panicle seed setting rate, thus affecting yield. Rice raised increase in amount. Under condition deficit had certain negative indexes, resulting slight decrease However, input significantly decreased compare flooding comprehensive application, high (40 highest, an average 91.05% compared Therefore, can substantially save input, stably yield, ultimately improve efficiency.

RICE CULTURE Effects of Water-Saving Rice Cultivation Methods on Yield, Water Use, and Water-Use Efficiency
Water available for irrigation is declining in many rice-growing regions around the world. Global populations continue to rise increasing crop production demand. Rice production systems must face the dilemma of maintaining or increasing yields with less water available to irrigate. Alternate wetting and drying (AWD) has shown to be an effective tool for water conservation in irrigated rice syst...
متن کاملResponse of different rice cultivars (Oryza sativa L.) to water-saving irrigation in greenhouse conditions
Due to increasing water and growing demand for food a more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving condition...
متن کاملEffects of Irrigation with Saline Water on Crop Growth and Yield in Greenhouse Cultivation
Since the salinity of irrigation water is a critical constraint to the production of certain vegetable crops, salinity has been considered as one of the most important factors of irrigation water. The objective of this study was to investigate the response of lettuce and Chinese cabbage to various salinity levels of irrigation water in greenhouse cultivation. A pot experiment was conducted with...
