Bioeffìcacy of different herbicides in fenugreek

摘要

Fenugreek (Trigonella foenum-graecum L.) locally known as 'Methi' in Hindi, is an important multi use leguminous spice crop of arid and semi-arid regions of India. India is the largest producer of fenugreek in the world where Rajasthan, Gujarat, Uttarakhand, Uttar Pradesh, Madhya Pradesh, Haryana and Punjab are the major fenugreek producing states. Rajasthan produces the lion's share of India's production, accounting for over 80% of the total fenugreek output (Anonymous 2012). In Haryana, the crop issown in an area of 4978 ha with seed production of 13,973 tonnes (Anonymous 2009). Growth of fenugreek is very slow in the initial stage and it does not form a canopy that can suppress weed growth upto several weeks after sowing. Pendimethalin has beenrecommended to control weeds but it efficacy is for short period and is inconsistent. Weeds which come up after first irrigation also cause huge losses. Keeping it in view, present experiment was planned to study effectiveness of imazethapyr and its ready mix combination as pre-plant incorporation (PPI), pre-emergence (PE) or post-emergence applications (PoE).
