Abstract
Pigeonpea (Cajanus cajan) is one of the most important pulse crops of India after chickpea also known as Arhar, Red gram, Tur, No eye pea, and Congopea. Rainy season, slow initial growth and sowing at wider spacing of pigeonpea encourage rapid growth and severe infestation of weeds. Greengram (Vigna radiata) is another important pulse crop. Pigeonpea being long duration, wide spaced, slow growing at early stage offers a great scope for intercropping short duration, fast growing and non-competitive intercrops with dissimilar growth habit. The field experiment was conducted at Research farm, Department of Agronomy, CCS HAU, Hisar during kharif season of 2021 & 2022. The experiment was conducted in a split plot design having 3 replications; each having two main plot treatments of cropping systems and 14 sub plot treatments of weed management. Four pre-emergence and two post emergence herbicides were evaluated. Combination of hoeing following the pre-emergence herbicides and two hoeings were also included. Sequential combination of pre and post emergence herbicides were also tested. Weedy check and weed free were maintained throughout the experiment. Results of experiment revealed that application of pendimethalin + imazethapyr (RM) @ 1000 g/ha was most effective pre-emergence herbicide among the tested herbicides and yielded highest crop equivalent yield and weed control efficiency (wce). Hoeing at 45 DAS following the pre-emergence herbicides further increased the crop equivalent yield and wce. Post emergence application of herbicides also provided satisfactory results. Highest crop equivalent yield and wce was recorded under two hoeings closely followed by pendimethalin + imazethapyr (RM) @ 1000 g/ha fb hoeing at 45 DAS.
