EFFECTS OF WATER STRESS ON MORPHO-PHYSIOLOGICAL CHARACTERS AND YIELD OF RICE GENOTYPES (Pages : 6 - 11)

A pot experiment was carried out at the Bangladesh Institute of Nuclear Agriculture, Mymensingh during aman season from August to November, 2005 to assess the effect of moisture on growth and yield of ten rice genotypes. The ten genotypes included in this study were TNDB-100, BRRIdhan 28, BINAdhan 4, MR-150/11, Ukunmadhu, RM-100/24, RM-100/18. The soil moisture levels were 100% (control), 70% and 40% field capacity (FC). The experiment was laid out in a randomized complete block design with three replications. All the yield and yield contributing characters were the highest at 100% FC and lowest at 40% FC. The highest number of leaves, leaf area, leaf dry weight, stem dry weight, root weight, total dry matter, panicle weight, number of panicle and grain yield were found in RM-100/18. The highest number of leaf, leaf dry weight, root dry weight, stem dry weight, panicle weight, total dry matter, number of panicle and grain yield were found in the treatment combination of RM-100/18 with 100% FC. The highest plant height was recorded in the treatment combination of MR-150/11 with 100% FC.Download
