Abstract:

A field experiment was conducted during kharif of 2014-15 at Main Agricultural Research Station, Dharwad to study the effect of early post-emergence herbicide Imazethapyr on weed dynamics and yield of greengram. Results revealed that weed free check (T10) recorded significantly lower total weed population, total weed dry weight of weeds, higher weed control efficiency (WCE), higher grain yield (833 kg ha-1), haulm yield (2685 kg ha-1), number of pods plant-1 (15.49), grain weight plant-1 (4.32 g) and gross return (Rs 40,707 ha-1), However, treatments T8 (Standard check 2 IC + 2 HW at 20 and 40 DAS) and T6 (Imazethapyr 10% SL @ 75 g a.i. ha-1 + adjuvant @ 2.0 ml litre-1 of water) found to be at par with T10. Among the herbicide treatments, T6 recorded significantly higher grain yield (783 kg ha-1), haulm yield (2528 kg ha-1), number of pods plant-1 (15.06), grain weight plant-1 (4.08 g), gross return (Rs 38,269 ha-1), net return (Rs 19,090 ha-1) and B: C ratio (2.00). It also recorded lower total number of grassy weeds, broad leaved weeds, sedge, total weed dry weight and higher WCE at 40 (86.49 %), 60 DAS (82.93 %) and at harvest (82.30 %).
