Effect of Different Weed Management Practices on Quality Parameters in Soybean - Pigeonpea Intercropping System

Abstract

Pigeon pea (Cajanus cajan L.) is a vital legume recognized for its widespread cultivation and its essential contribution to the global economy. The experiment aims to study the effect of different weed management practices on quality parameters in a soybean–pigeonpea intercropping system. The study was conducted at the Agricultural Research Station, Anand Agricultural University, Derol, District Panchmahal, Gujarat during the kharif seasons of 2017–18 and 2018–19. Ten weed management treatments were evaluated in a randomized block design with four replications. The results of pooled analysis revealed that effective weed control was achieved through interculturing + hand weeding at 20 and 40 DAS, followed by post-emergence application of imazamox 35% + imazethapyr 35% (pre-mix) at 70 g ha⁻¹ PoE followed byinterculturing + hand weeding at 30 DAS. This treatment recorded higher protein and oil content and yield in soybean and higher protein content and yield in pigeonpea. The lowest protein, oil content and yield was observed under the weedy check treatment.
