Studies on the pre-emergence herbicides in sunflower (Helianthus annuus L.) under graded doses of nitrogen

, : Studies on the pre-emergence herbicides in sunflower (Helianthus annuus L.) under graded doses of nitrogen. Madras Agricultural Journal 61(8): 490-496

In trials with sunflower, pre-emergence application of 1 kg prometryne, 2 1 nitrofen or 1 kg terbutryne a.i./ha gave effective control of weeds and resulted in seed yields of 1.88-1.93 t/ha, compared with 1.89 t/ha on plots given 2 hand-weedings and 1.2 t/ha on those given no hand-weedings or herbicides; application of 1.5-2 kg alachlor a.i./ha was less effective. All herbicides increased seed oil contents.
