abstract
The experiment was undertaken at Rajmohini Devi College of Agriculture & Research Station, Ambikapur (C.G.). Significantly higher number of capitulum setting plant-1 was obtained in treatment with control (36.19 capitulum plant-1). However, the lowest capitulum plant-1 was found with total closed (29.08 capitulum plant-1. The maximum weight of capitulum-1 was observed in treatment with control (0.244 g capitulum-1) but the minimum capitulum-1 weight was found in treatment with total closed (0.094g capitulum-1). The highest seed yield plant -1 was recorded in treatment with control (2.33 g plant-1) and the lowest seed yield plant-1 was obtained in treatment with total closed (0.76 g plant-1). But significantly highest healthy seed was noticed in treatment with control (95.60 per cent). However, the lowest healthy seeds were found in treatment with total closed (3.17 per cent).
