Abstract:
A field experiment was undertaken at the All India Coordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra. The experimental field was infested with various weeds to control weed infestation some integrated practices were followed. Based on two year experimentation, it was found that, during kharif of 2015, 2016 and pooled treatment weed free check reported significantly highest weed control efficiency than rest of all the treatments as there was total eradication of weeds which resulted in achieving 100% weed control efficiency. Post emergence application of herbicides in integration with the hand weeding gave better control of weeds during crop growth period which lowered the total weed population and ultimately resulted in achieving higher weed control efficiency. This could be explained based on the fact that, maximum uptake and better assimilation of herbicides was pronounced as soon as weeds emerged. Less weed intensity and its dry weight in integrated weed control treatments compared to weedy check may also one of the reasons of higher WCE with these treatments. Pooled data of two years indicated that significantly maximum pod yield was recorded due to increase values of yield attributing characters due to favorable environment in the root zone resulting absorption of more water and nutrient as less crop weed competition during critical stage.
