Abstract

 A field investigation was planned during rabi season of 2011-12 and 2012-13 at Research Farm of
Department of Agronomy CCS Haryana Agricultural University, Hisar to study the efficacy of different
herbicides integrating with hand weeding in chickpea. Various treatments included were trifluralin 750 g/ha
PPI (pre plant incorporation), trifluralin 750 g/ha PPI + 1 HW (hand weeding) 45 DAS (days after sowing),
trifluralin 1000 g/ha PPI, trifluralin 1250 g/ha PPI, pendimethalin 750 g/ha PPI, pendimethalin 750 g/ha
PPI + 1 HW 45 DAS, pendimethalin 1000 g/ha PPI, pendimethalin 1250 g/ha PPI, pendimethalin 750 g/ha
PRE (pre emergence), pendimethalin 750 g/ha PRE + 1 HW 45 DAS, pendimethalin 1000 g/ha PRE,
pendimethalin 1250 g/ha PRE, 1HW 30 DAS, 2 HW 30 and 60 DAS, weedy and weed free check. The seed
yield and various yield attributes of irrigated chickpea were increased when trifluralin (PPI) or
pendimethalin (PPI & PRE), each at 750 g/ha integrated with 1 HW at 45 DAS, and these were comparable
to the treatment of 2 HW (30 and 60 DAS) and also to the weed free conditions. In chickpea, the PPI
application of pendimethalin was superior over PRE application, however there was no significant
differences in yield. Weeds allowed to grow through the crop season reduced the seed yield of chickpea to the
extent of 31.29 and 25.49 % during 2011-12 and 2012-13, respectively.
