Abstract
A field experiment entitled “Integrated Weed Management in Lentil (Lens
culinaris Medic L.) under different planting techniques” was conducted at pulse
research area, CCS Haryana Agricultural University, Hisar during rabi season of
2005-06. The experiment was laid out in split plot design allocating planting
techniques (Zero tillage, Raised bed and Flat bed) and irrigation (No irrigation and
One irrigation at flowering) to main plot and the weed management (weedy check,
Hand weeding at 30 DAS and pendimethalin @1.0 kg a.i. ha-1) to sub plot with three
replications.
It became evident from the findings of the present investigation that raised bed
proved superior over flat bed planting and zero till planting. However, flat bed gave
better yield than zero till planting. Irrigating the lentil crop at the time of flowering
will give more yield over no irrigation. Under weed management practices
pre-emergence application of pendimethalin @1.0 kg a.i. ha-1 proved superior over
one hand weeding at 30DAS and weedy check. The best combinations were raised bed with one irrigation at the time of
flowering and raised bed with pendimethalin @1.0 kg a.i. ha-1 application over other
treatment combinations. When irrigation was applied to the pendimethalin treated
plot it gave better results than the other treatment combinations.
