Plant dry matter accumulation, Productivity, Profitability

A field experiment was conducted at Birsa Agricultural University, Ranchi during rainy season of 2014 to study the efficacy of weed control methods as a suitable integrated weed management for better production of turmeric. Dry matter accumulation by total plant parts was maximum under atrazine 0.75 kg/ha pre-emergence (PE) followed by (fb) straw mulch at 10 DAP fb hand weeding at 75 DAP at all the stages. Application of atrazine 0.75 kg/ha PE fb straw mulch at 10 DAP fb hand weeding at 75 DAP recorded higher rhizome yield consequently higher gross return (` 725917/ha). However, maximum net return (` 621216/ha) and B:C ratio (5.93) was recorded with application of atrazine 0.75 kg/ha PE fb straw mulch at 10 DAP fb hand weeding at 75 DAP.
