Influence Of Maleic Hydrazide And Triiodobenzoic acid On Morpho-Physiological Tŕaits , Yield And Yield Contributing Parameters Of Mustard

: An experiment was conducted at farm of botany section, college of agriculture, Nagpur during rabi 2015-16 to study the effect of one foliar spray of MH and TIBA at different concentrations (25 ppm, 50 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm MH and 25 ppm, 50 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm TIBA with the control) on the morpho-physiological and yield and yield contributing parameters of mustard cv. ACN-Shatabdi. Data revealed that foliar application of 50 ppm TIBA followed by 100 ppm MH significantly enhanced morpho-physiological parameters viz., number of branches plant -1 , leaf area plant -1 , total dry weight of plant and NAR and RGR over control. Similarly yield and yield contributing parameters viz., number of siliqua plant -1 , number of seeds 20 -1 siliqua, 1000 seed weight and seed yield ha -1 also significantly increased over control. Significant reduction in plant height was noted in treatments receiving MH and TIBA when compared with control. The heighest B:C ratio was observed by the foliar application of 100 ppm MH (2.18) followed by 50 ppm TIBA (2.16) and 125 ppm MH (2.09) and can be considered as the most effective and beneficial treatments in mustard.
