Influence of moisture regime on the yield performance of hyv rice in bangladesh

Abstract

Abstract: Conducting an experiment with six moisture regimes, saturation to 0.10 bar tension was found to be superior. Similar yields were also found in the continuous standing water, continuous saturation and 15 days standing water followed by soil drying upto 0.20 bar tension. Yield was sharply reduced when the soil moisture was always maintained from saturation to 0.20 bar. Plant height, ear length and 1000-grain weight were favoured by the continuous standing water but saturation to 0.10 bar tension favoured the tillering habit. Saturation to 0.20 bar tension adversely affected almost all yield attributes.
