Economics, Field pea, Imazethapyr, Pendimethalin, Weed management

A field experiment was conducted at Agronomy Research Farm, Division of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Wadura during Rabi seasons of 2021-22 and 2022-23 to study the effect of sequential application of herbicides on weeds and yield of field-pea under temperate conditions. The experiment consisted of 14-treatments which were tested in a complete randomized design replicated thrice. Weeds caused 63.8 and 61.0 per cent reduction in seed yield of field pea during 2021-22 and 2022-23, respectively. Among the herbicides tested, pre-emergence application of pendimethalin 1.00 kg/ha followed by post-emergence application of imazethapyr 0.125 kg/ha recorded significantly lowest weed biomass, weed index and highest weed control index, field-pea growth and yield attributes, seed and stover yield, and better economics over the rest treatments. Hand weeding recorded higher growth and yield of field pea but it was not cost-effective.
