Abstract
The present study was undertaken to explore the allelopathic capability of Anthocephalus cadamba leaf litters on four common pulses viz. Pisum sativum, Phaseolus mungo, Cicer arietinum and Lens esculenta uncovered critical hindrance of seed germination and seedling development. The leaf powder obtained after shade drying (1, 2, 5 and 10 g) was doused independently in 100 ml distilled water for a day and a half (36hrs). Application of this leaf extracts reduced seed germination rate and suppressed early seedling growth. With increase in extract concentration from 1 to 10%, a slow abatement in seed germination and seedling length happened. The inhibitory impacts were relative to the groupings of leaf separates and the higher fixation (5-10%) had more inhibitory impacts. Among the test crops, Cicer arietinum and Pisum sativum seeds were least touchy to the utilization of different groupings of leaf extracts while Lens esculenta and Phaseolus mungo seeds were more helpless to the allelopathic impacts of Anthocephalus cadamba. The results suggest that leaf extracts of Anthocephalus cadamba had strong allelopathic activity although the activity differed depending on concentration. The current investigation could be significant in arranging the field under various harvests considering the common agro-biological system for better return. It is also suggested that these pulses should not be planted close to Anthocephalus cadamba due to unfriendly impacts on their development and advancement. These results suggested that the A. cadamba had allelopathic potential which decreases germination and plant development.
