Abstract:
On calcareous clayey medium black soil in Junagadh (Gujarat, India), a field investigation was conducted throughout the seasons of kharif and rabi, 2021–22 and 2022–23 to investigate the effects of various pre and post–emergence herbicides on pigeon pea and their combination with hand weeding. Pre-emergence application of pendimethalin 1000 g/ha fb IC & HW at 30 and 60 DAS was found to be equally effective as weed free in controlling weeds and improving growth, yield attributes, yield and quality parameter viz., plant height, branches/plant, number of pods/plant, seed and stalk yields and protein content in seed, subsequently oxyfluorfen 180 g/ha as pre-emergence(PE) fb IC & Hand weeding at 30 and 60 DAS and IC & Hand weeding at 20 & 45 DAS fb glyphosate 900 g/ha or glufosinate ammonium 400 g/ha as post-emergence(PoE) at 75 DAS. Whereas, highest net economic return (Rs. 136215/ha) and B:C (3.38) was noted in with application of pendimethalin 1000 g/ha as pre-emergence fb IC and HW at 30 and 60 DAS.
