Effect of weed management on growth and yield performance of wheat under Eucalyptus tereticornis based agroforestry system

Abstract

A field experiment was conducted during winter season to find out the growth and yield performance of wheat (Triticum aestivum L.) crop with weed control treatments under eucalyptus based agroforestry system. An experiment was conducted at the farmer field village- Majitha, District- Jabalpur during the rabi season of 2016-17 and 2017-18. The field was infested with 5 major weed species Phalaris minor, Rumex dentatus (L.), Meliotus indica (L.), Chenopodium album (L.) and Launaea nudicaulis (L.). Minimum weed density per m2, weed dry weight (4.17 and 1.57 q ha-1) and NPK uptake (1.77, 0.23 and 2.73 kg ha-1) was found under hand weeding 30 DAS over weedy check. The maximum weed control efficiency, grain yield, straw yield and harvest index was recorded under hand weeding 30 DAS (91.12%, 18.97 q ha-1, 43.13 q ha-1 and 30.61%). Maximum nutrient uptake was also recorded in these treatments. Post emergence herbicides and /or hand weeding can further enhance the weed suppressive effect of the crop under Eucalyptus tereticornis based agroforestry system.
