Effect of mulching and pre-emergence herbicide on yield and economic of wheat (Triticum aestivum L.)

Abstract

The experiment was carried out at crop research farm Dev Bhoomi Uttarakhand University Dehradun, Uttarakhand India. The university crop research farm is located near Dehradun in the state of Uttarakhand. The location's coordinates are approximately 77.9326° E longitude and 30.3841° N latitude. At 410 metres above mean sea level, the location of the site is marked. This study aims to investigate the effects of pre-emergence and mulching on the wheat variety PBW-550's yield and economics. The study explores the impact of weed management and mulching on wheat production growth characteristics and financial outcomes. Results show significant impacts on plant height, leaf area, and dry weight, with straw mulching resulting in higher grain and stover yields. The findings showed that the treatment (T7) combination of straw mulch (Paddy Straw) + (Two hand weeding) was shown to considerably increase grain production (4.41 t/ha), gross returns (Rs. 2,61,491.45 /ha), net returns (Rs. 1,58,190 /ha), and benefit cost ratio (2.42).
