Weed control efficiency (%) as influenced by baby corn + field pea intercropping and weed management

Abstract

A field experiment was conducted during rabi season 2010-2011 and 2011-2012 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India). To study the Effect of Planting pattern and Weed management in Baby corn (Zea mays L.) intercropped with Field pea (Pisum sativum L.). Weed control efficiency did not differ significantly due to various planting pattern. However, paired row planting system and normal planting pattern remained at par to each other and recorded higher weed control efficiency (%) than sole planting. Further perusal of the data revealed that weed management practices recorded significant variation in weed control efficiency. At 30 DAS, hand weeding at 25 DAS recorded higher weed control efficiency and remained at par to pre-emergence application of pendimethalin @ 1.0 kg ha-1. However, at 60 and 90 DAS post-emergence application of imazethapyr @ 50 g ha-1 was significantly superior and was most effective in increasing the weed control efficiency.
